Restaurant 1000 heralds McDonald’s Australia’s sustainable future

McDonald’s Australia has heralded a new era of sustainability by opening its 1000th restaurant as the company’s sustainability flagship for Australia.

As part of the project, WaterGroup has deployed its smart water metering solution into the flagship restaurant, forming one of 25 core sustainability initiatives the restaurant is using to reduce its environmental impact with the aim to test, evaluate and implement industry-leading sustainability innovations into the future.

“At WaterGroup, saving water for our customers is our top priority. We are so proud to assist McDonald’s with our state-of-the-art technology to achieve real savings,” WaterGroup Managing Director Guenter Hauber-Davidson said.

“Leaking pipes, leaky toilets, fixtures, valves or sprinklers are some of the typical causes of abnormally high water use. With our solution in place, the Melton South restaurant can quickly identify when these occur to save water and money.”

McDonald’s Australia National Director of Development Diana Grosmann said, “As a sustainability innovation hub, Restaurant 1000 will play a crucial role in enabling us to continue to design and build commercially practical sustainability solutions into every new Macca’s restaurant in the years to come.”

McDonald’s Australia Director of Supply Chain and Sustainability Kylie Freeland added, “Through collaboration with the franchisee of the restaurant, as well as partners like WaterGroup, we hope that Restaurant 1000 will allow us to learn quickly and expand successful innovation trials that enable us to continue to implement practices, equipment and products to improve our environmental impact.”

WaterGroup’s smart water metering solution comprises a smart NB-IoT-enabled logger that connects to a site’s existing water meter. The data from that meter is then sent to the cloud and is accessible via a client-facing portal. At Melton South they also have WaterGroup’s AWARE service, where the WaterGroup team monitor and alert the restaurant of unusual water usage turning insights into action.

During the 2019 financial year, WaterGroup has delivered measurable outcomes for its clients with water savings of almost 300 million litres and cost savings of more than $1 million.

“We wish the McDonald’s South Melton team great success with their new restaurant and look forward to saving them water and money,” Hauber-Davidson said.

Other sustainability initiatives

Restaurant 1000 customers will be served a series of new packaging items including paper straws, wooden cutlery and paper sundae cups, as McDonald’s Australia continues to phase out all plastic straws and plastic cutlery from its restaurants nationwide. The collective impact of these transitions will remove 860 tonnes of plastic from the McDonald’s system.

The restaurant will also incorporate energy-efficient air-conditioning systems, hydrocarbon equipment and a building monitoring system to help collectively reduce carbon emissions and energy used.

“Over the coming three years we plan to invest more than $500 million to open over 80 new restaurants across Australia, incorporating a range of core sustainability elements from Restaurant 1000, including PlayPlaces made with recycled content and energy-efficient equipment, as well as the use of 100% renewable energy at some restaurants.

“Through partnership with the franchisee of the restaurant, Ben Westover, we hope Restaurant 1000 will allow us to learn quickly and expand successful innovation trials, so we can continue to implement practices, equipment and products to improve our environmental impact,” Grosmann said.

In early 2021, Restaurant 1000 will commence trialling a front-of-house waste recycling system, as the business moves towards achieving its goal of diverting front-of-house waste from landfill. The trial will see front-of-house waste from Restaurant 1000 recycled into carry out bags and wraps packaging.

Full list of sustainability initiatives implemented at Restaurant 1000

Building infrastructure and furnishings incorporating recycled content and natural aggregates.

With the help of Energy Australia, Restaurant 1000 will be powered entirely by renewable energy.

On-site solar panels installed on a custom roof structure over the drive-thru. The entire solar system at the restaurant is expected to generate 42,000 kWh per year.

Families will be able to introduce their children to recycling via a specially designed Happy Meal toy collection bin. Through our reverse logistics system, pre-loved Happy Meal toys will be returned to our distributor before being provided to a third party for recycling.

The PlayPlace equipment utilises old play equipment repurposed into new decks, climbers, slide tubes and window panels — 60% of the entire structure is sourced from old Macca’s play equipment, with the remaining 40% of material being 100% recyclable at end of life.

Carbon-neutral McDelivery via Uber Eats and DoorDash, where carbon credits will be used to offset the emissions from deliveries made from Restaurant 1000 for 12 months.

McDonald’s distributor will act as a consolidation for waste streams such as cardboard, cups, coffee grinds and soft plastics and return these to a central location, creating opportunities for circular economies.

All lighting and signage at Restaurant 1000 utilises LEDs, which use around 80% less energy than neon systems, meaning there’s less strain on the environment and electricity grid. LEDs also don’t include any toxic gases and are cleanly recycled.

The green wall at the entry to Restaurant 1000’s dining room, full of living plants that increase biodiversity, provides insulation and clean the air.

Wheel stops and kerbing throughout the drive-thru and car park are made from recycled cups and plastics. The wheel stops are made only from cups and plastics from McDonald’s restaurants and not only complete the loop for a circular economy, but are more hard-wearing than concrete alternatives.

Two electric vehicle charging stations provided by Evie Networks, and supplied by 100% renewable energy.

A bulk oil supply system that pumps bulk oil directly from the tanker into a plumbed tank in the restaurant, reducing the cardboard and plastic packaging, which would have previously been delivered each week.

Similar to the bulk oil supply system, the restaurant utilises a bulk milk system that will remove the need for approximately 1650 kg of plastic bottles from the restaurant.

Strategically placed sensors will monitor the amount of sunlight shining into the restaurant. If it’s a bright day, the sensors will automatically dim the lights in the dining room to conserve energy.

Hydrocarbon refrigerant equipment will vastly reduce the carbon footprint of the restaurant due to its low Global Warming Potential and Zero Ozone Depleting Potential.

A high-efficiency air-conditioning system that doesn’t generate as much heat and therefore doesn’t force the system to work as hard to cool. This means the air conditioning system is up to 32% more efficient than the minimum BCA-compliant system.

Paper straws, wooden cutlery, paper sundae cups and a new type of wrap that can be composted will all be trialled at the restaurant.

All irrigation on-site will utilise two 5000 L water tanks that collect and harvest rainwater.

Using specialist technology provided by WaterGroup, water usage will be monitored by a cloud-based system that will help to identify any anomalies so any leaks are addressed early.

The restaurant will also use a heat recovery hot water system that absorbs heat from the air-conditioning system to heat water. This system is more efficient than conventional water heaters and reduces greenhouse gas emissions.

All timber cladding is Programme for the Endorsement of Forest Certification endorsed.

A building-monitoring system will assist McDonald’s to optimise energy use while the restaurant serves customers. Any anomalies in the air conditioning, lighting and refrigeration system will trigger an alert so the restaurant can rectify immediately.

Save up to £100 in energy bills with this simple garden swap

Longer, warmer days mean more time spent in the garden. but,  if you’re not careful that time in the garden could be causing a bump in your energy bills.  Here are a few simple swaps  you can  do to save on energy bills in the garden.

Related: Brilliant budget garden ideas that will boost your outdoor space without breaking the bank!

Summer is usually a time when household running costs are at their lowest. The heating is off or on low, and the electricity only needs to be turned on for a few hours in the evening.

However, if you still get slapped with a large energy bill in June the cause could be in your garden. Data experts at Loop, the home energy-saving assistant, have revealed that homeowners could be missing out on huge savings in their garden.

‘Creating an energy-efficient home isn’t just about what’s on the inside,’ explains Steve Buckley, Head of Data Science at Loop. ‘As the weather gets warmer, now could be the perfect time to transform your garden into an energy-saving haven.’

Here are five easy ways to save energy (and money) in your garden.

Save on energy bills in the garden

1. Switch to solar lighting

Garden lights might look pretty, but when left on all night they can rack up a hefty bill.

‘With warmer weather and longer days ahead, it’s important you take the time to change any garden light that runs on timers,’ advises Steve. ‘Make sure you switch off those you don’t need to keep on before you go to bed too.

‘Two outdoor 60W lights left on overnight could add up to £63 to your yearly bill,’ he adds.

To make even bigger saving consider opting for solar powered garden lights. Not only are they cheaper to run, but they are also less disruptive to wildlife as they emit a dimmer glow.

2. Don’t get carried away with the pressure washer

Pressure washers are perfect for getting neglected patios and garden furniture gleaming again. However, resist the urge to reach for it too often.

‘Pressure washers are generally rated between 1.5 and 3kW meaning every hour’s use could cost up to 55p,’ explains Steve. they can also get thought a lot of water, with the most powerful models using more than 500 litres an hour – another additional cost worth considering if you’re on a water meter. ‘

If you have anything around the garden that can be cleaned with bucket and sponge, consider making the swap and save yourself a few pounds.

3. Add a windbreaker to the garden

Image credit: Lizzie Orme

‘If your home is exposed to strong winds, then you could be losing warmth and face higher bills s a result,’ says Steve. ‘But the right landscaping or windbreaks can lower the wind chill near your home and reduce heating costs considerably.’

This doesn’t mean putting up one of those tarpaulin numbers used at the beach. Instead consider investing in a hedge, fence or row of trees that will shelter your home from strong winds.

4. Heat your greenhouse efficiently

Using a heater in your greenhouse could be adding more than £30 to your annual energy bill, Loop reveals.

‘Using a heater with a thermostat is a must, but if yours doesn’t have one make sure you remember to turn it off when the weather warms up or use a timer instead,’ suggests Steve.

You can also help cut down on energy costs by improving the insulation in your greenhouse, this can be as simple as adding a layer of bubble wrap.

5. Install a water butt

If you have a water metre, keeping the plants watered in summer can quickly add up. Fitting a water butt to catch and store rainwater is a great way to cut down on the water you are using. Simply swap the hose for a watering can.

Solar water heater 100 ltr price in Bangalore

Solar water heater 100 ltr price in Bangalore

Solar water heater 100 ltr price in Bangalore, You should know about solar power first before going for any solar thermal system. Solar thermal system is based on the principle of converting sunlight into hot water (or steam) for use in heating homes and buildings. Solar water heating systems, commonly called solar hot water systems, convert the sun's rays into energy using a black-body absorber located inside a glass collector. When the temperature drops below, however, the efficiency decreases rapidly. Most solar thermal collectors have a maximum working temperature . To install a Solar water heater 100 ltr price in Bangalore, contact Jupiter Solar , www.jupitersolars.in .

What Is A Solar Water Heater?

What Is A Solar Water Heater?,a solar water heater is a device that converts solar energy into useful heat. These devices utilize the power of the sun to create a warm liquid that can then be applied to our homes and businesses. In effect, a solar water heater is similar to a conventional electric water heater; however, instead of electricity, sunlight does the work. Our bodies need water to survive and if we do not drink enough water, we become dehydrated. If we live in a desert area where there may not be much access to fresh drinking water, having access to heated water would be helpful.  Thus, a solar water heater could be a cost effective and environmentally friendly alternative.Buy solar water heater , contact Jupiter Solar , www.jupitersolars.in .

How Does Solar Power Work?

Solar powered water heaters make use of the sun's heat and convert it directly into usable hot water. There are several different types of solar water heaters depending on the desired output. The two basic designs are a direct (concentrating type) and indirect (reflecting type). Direct solar water heaters focus the sun's rays onto copper tubes , while indirect solar water heaters reflect the sunlight back towards the tubes. Both of these types of units produce hot water at high efficiencies, although the concentrating type has higher operating costs.

Cost And Efficiency Of Solar Water Heaters

To calculate how much you might save with a solar water heater, you'll need to determine the size and capacity of your current system along with an estimate of the total annual usage. Next, you'll need to figure out how much electricity you currently spend on your utility bill. Then simply divide those figures together. Your savings are determined by dividing the difference between your estimated monthly expenses and what you'd pay by the amount of energy your solar water heater produces. Let's assume you're saving $40 per month on your utility bills - that equals $480 annually. To calculate the approximate number of gallons of hot water produced by your existing system, multiply the volume of your tank by the average flow rate. Once again, let's say you have 5 gallons of storage capacity and your current flow rate is 10 gallons per day. That means you're producing 500 gallons of hot water each year. Divide that by 12 months to find your monthly consumption. Now subtract both the $240 annual savings and the $500 annual production from the $960 total cost of your present system. What's left over is how much money you stand to save by switching to a solar water heater.

Size And Capacity

You'll want to consider the size and capacity of the solar water heater you plan to install before making a decision. Many manufacturers offer models ranging from 100 litre to 200 solar water heaters. The larger the system, the greater the potential savings. Smaller systems can be installed outside while larger ones may requires a free standing structure . A good rule of thumb is to buy the largest solar heater unit possible. Keep in mind that the size of your home or business building will affect the size and weight of your solar water heater. Obviously, larger homes and buildings require bigger and heavier units.

Installation

Most solar water heaters are preassembled and ready to go once you've purchased them. However, they do require some installation work. After placing the solar heater unit in its final location, you'll need to add the hardware. Finally, fill the reservoir with water. Depending on where you live, the process may take a few hours before you start receiving hot water.

Maintenance

Solar water heaters don't require very high maintenance once they've been installed. You won't need to worry about replacing the elements until the solar water heating units are working or cleaning the panels since their performance will remain unchanged. However, you may want to clean the surface of the black-body absorbers every so often. Fortunately, they are easy to remove and replace. Also, remember to keep your unit clear of debris such as snow and leaves.

Water Heater

Water heating systems are used to warm water for bathing, cooking, washing purposes, etc. A solar water heater uses solar power to heat the water directly without using any fuel. In some cases, they use a storage tank where hot water is stored until required. These tanks are filled once a day and then heated by the sun. Heating water by boiling is considered efficient since many percentage of the energy goes . Solar water heaters, however, convert this thermal energy into electricity . Energy efficiency is thus increased. Other types of water heaters are gas-based, electric ones.

Storage Tank

The storage tank is the place where hot water is kept. When the temperature drops below a certain level, the pump sends water back to the boiler. Another type of storage tank is the closed loop system where water circulates continuously between the boiler and the tank.

Boiler

A boiler is a device that takes water at room temperature and heats it to high temperatures. Once the water reaches these high temperatures, it is sent to a tank where the excess heat is removed and converted to useful energy. Depending on the size of the boiler, it may need to have a fan inside to remove extra heat. The fan can either run constantly or only while the water is being pumped.

Pumping System

Pumping systems move water from one point to another. There are many different pumps, but some of the most common ones include centrifugal, screw, and piston pumps.

Electric Motor

Electric motors are the devices that turn the mechanical energy of steam or electrical energy into kinetic energy. An electric motor uses electric current to create rotating force. The rotor spins within the stator, converting it to rotary motion. The electric motor converts electrical energy into rotational energy which is then transferred to the shaft turning the impeller blades.

Impeller Blades

Impellers are the blades that are attached to the shaft. To improve efficiency, the blades spin faster by increasing RPM (revolutions per minute). The higher RPM increases the pressure of the water pushing it outward forcing it to flow around the outside of the impeller blades. This helps the water leave the impeller blades in a continuous stream and exit the unit.

Air Pump

Air pumps help move air across surfaces, keeping them clean and preventing mold and bacteria buildup. Air pumps are often used in air conditioning units to move cool air over coils and condensers.

                    How living on a boat has changed my life  

The number of people who consider to change their life and go to live  on a boat in London is increasing more and more.

According to an analysis by Savills ,emerged in 2016, the prices of the houses in London has risen in value by 105£ a day since 2012. This leads  the majority of the people to choose to live on a boat as a more affordable option.

Consequently, the number of people living on a boat has increased, according to the statistic of Canal River Trust on 2016, by almost 60% since 2012.

But, is anyone able to live waterway?

                                           The story of Jonas

                  “I choose to live my life as better fit for me”, Jonas.

Jonas is a 33 years old man from Brazil and he has been living on a boat for more than two years. ” It is this way of life that makes me stay in London”.

Before moving to London, three years ago, Jonas was working in Brazil as a engineer and as he said, his life was well organised, since ” I felt my life was passing and I neededto do something“. ” I was living in San Paulo that is a way bigger and crowded city than London. I have always had a motorcycle to move fast and go hand in hand with my busy lifestyle. I really enjoy the calm and quiete now.”

Why did you decide to live on a boat?

“When I first came to London I was living in a sharing house, one day a friend of mine told me he needed to get rid of his boat for work reasons and he could not take care of it anymore. He offered me to stay in the boat, he spent days showing me how it works and explaining me everything. For me it was just amazing and all I could do was accept.”

How did you adapt your life on the boat?

“I did not really have problems finding myself here. I never felt like I wanted to go back or this is not working. Of course living on a boat is not really practical, it demands a lot of attention, there are always things that you need to fix or improve but I got used to it now. And somehow it is similar to living in a house, you have everything, but just  smaller.”

What about the maintenance and costs?

“Regarding the costs if you have the continuous cruiser license, ( it means you need to move every two weeks) you will have to pay it annually and the cost depends on the size of the boat, for mine it is around 800 £ a year. I also pay the insurance, 170£ a year. This includes all the services you will need.

For the maintenance there are few supplies you need. First the gas (diesel) that you can charge directly from a supply boat passing along the canal. Then concerning the toilet, as I have a chemical toilet I need to throw the tank when it is full in a facility point. My boat does not have any heaters and I usually use stoves and wood for the cold winter. It is important you take care of all of that and think about your daily schedule: heating the boat, moving it every two weeks, empty the toilet. And I learned how to reduce my needs and to save what I can.”

“It is important to always keep in mind your daily schedule”

Have you made any changes to bring more comfort?

“I have made a few changes since I have been here.

First I installed the solar panels so now I usually use only that for electricity. Even during a cloudy winter, it is enough for the fridge, lights, charging phone and computer. Before, I needed to move many times as the battery charges when you move the boat and turn the engines on. Still moving from one neighbourhood to another was not enough to charge it. Now 95% of the energy is provided by the solar panels.

Water, is something else that I needed to change often. I always had to keep in mind how much water I was using as it came from a container. Before I had 100 litres container and I was changing it every 5 days. Then I decided to upgrade to a 1000 litres, meaning that I can change it every two weeks when I need to move.

Also, the boat before had a small transformer that was just plugging 12 volts, which you can actually just use to charge your laptop. I bought a bigger transformer and I changed the plug for 220 volts.”

What are the mooring rules?

“So, as I have a continuous mooring licence, I need to move the boat every two weeks. I have to go to the next borough, following my kilometre area (which is determined by which direction you are coming from). You need to keep going. And also really important is to move really slowly to not create waves and disturb the other boats.”

‘Canal River Trust’ is the organisation which takes care of all the canals and river in UK.

It is its job to examine how far the boats have moved during their cruising licence, and to see if it has satisfied the requirements it needs to follow.

How strong is the sense of community between boat owners ?

“It is really strong. When I first moved I did not know anything, I started to moor and all the people asked me if I needed help. They are really connected and help each other a lot. There is also a group on Facebook called “London Boaters”, there are around 4000 members and anytime you need something or you have an issue you can ask for advice.

“I have an example of the sense of community between us. Once I moored to Victoria Park and at that time I was working, some kids got into the boat and the alarm took around 20 seconds before it went off. When it, immediately the owner of the boat next to mine  went to check and he tried to catch whoever was in there and called the police. He also wrote to the Facebook group, asking if anyone knew the owner of the boat and exactly 15 minutes after I received a call from him. I was impressed, from that moment I started to feel part of a community.”

“I have been forced to slow down my life and appreciate the small things”

How do you do when you are asked for an address?

“This is a big problem and there is no solution. Since I am living on the boat I use the address of a friend of mine.”

What do you enjoy most living waterway?

“I enjoy the quietness of living on a boat. Having breakfast outside on a sunny day and feeling so connected with nature and the environment.I have been forced to slow down my life and appreciate the small things and I like this. Space was a big problem at the beginning. I do not have much space so I just started to give away things that I did not really need. If one day I will be living in a flat I am sure I will follow this routine. I can not tell to people if is worth or not living waterways because it depends on the person, but this way of life is what makes me stay in London.”

How does solar water heating work?

A solar water heating system uses solar thermal panels on your roof to heat water to use around your home. Fitting this type of water heating system isn’t cheap so, before you invest, you need to find out whether solar thermal panels are right for your home and your needs. Our expert advice will tell you how the system works, what you need to consider, and help make sure you get a good price from a reputable installer. Choose from the links below to jump straight to the section you want: How does solar water heating work? Types of solar thermal panels Solar water heating prices Can I save money with solar water heating? Are solar thermal panels right for my home? Pros and cons of solar water heating How to choose a solar water heating system How to find a good solar panel company What you need to know about solar thermal panel installation How to get the most from your solar thermal panels Do I need planning permission for solar thermal panels? If you’re looking to generate electricity, head to our guide on solar PV panels instead.

How does solar water heating work? Solar thermal panels use heat from the sun to warm fluid passing through them, as the diagram below shows. This is then used to heat your water, which is stored in a hot water cylinder. An immersion heater/unvented hot water cylinder might be needed as a back-up heater or to get the water to the temperature you want. Solar Thermal Panels Types of solar thermal panels There are two main types of solar water heating panels – flat plate and evacuated tubes (referring to the way the water interacts with the panel). Evacuated tubes look like a bank of glass tubes fitted to your roof. Related Articles : https://www.solarafter.com

Flat plate systems can either be fitted onto the roof or integrated into it. Evacuated tube systems are more efficient than flat-plate versions, so are often smaller but still generate the same amount of hot water. There are also drainback systems, which drain water from inside the solar panel when the pump is switched off. This prevents water from freezing or boiling inside the solar panel. Solar water heating prices Solar thermal panels typically cost between £4,000 and £5,000 to install, including VAT (at 5%). For comparison, a conventional gas boiler costs between £1,500 and £4,764 to install, although the cost will vary depending on how much work is required, parts needed, availability, where you live and who you employ to do the job. Find out more about how much a new boiler costs.

Once installed, additional costs are minimal. Most systems use a small amount of electricity to run the pump but, in most cases, the pumping costs cancel out only about 8% of savings, and newer technology can typically reduce this to 3% or even zero. You’ll need to bear in mind the cost of maintenance, although it's generally very low for solar water heating systems. For example, a replacement pump costs around £90 to replace, while new anti-freeze costs around £100. Most systems come with a five or 10-year warranty.

Can I save money with solar water heating? Savings with a solar water heating system are moderate. How much you can save depends on the type of water heating system you are replacing. Bear in mind that the system should be able to provide most of your hot water in summer, but much less in winter. As a general guide, you could save around £55 to £95 per year on your water bills with solar thermal panels. You’ll save most if you are currently using LPG (liquid petroleum gas) to heat your water – around £95 per year. If you are replacing gas central heating, savings are likely to be closer to £55 per year. How Do I Know If My Roof Is Suitable For Solar Panels https://www.solarafter.com/how-do-i-know-if-my-roof-is-suitable-for-solar-panels

Bill savings with solar water heating Besides reducing your fuel costs, you may be able to get payments from the government for the heat you generate. This is called the Renewable Heat Incentive (RHI) scheme and pays consumers for generating heat by using renewable energy, including using solar water heating. For a two-person household, you could earn an estimated £205 per year through the scheme. But to qualify for the RHI, your home will need to meet minimum energy-efficiency standards. Find out how much you could earn with the RHI. So we recommend that you first make sure your home is as energy efficient as possible, then think about which types of renewable energy technology, including solar panels, might suit you. And remember: the more energy efficient your house is, the less heat you'll lose and, therefore, the less heat you'll need to generate in the first place. This means that you should need a smaller heating system, which will be cheaper to buy and to run.

Are solar thermal panels right for my home? For maximum efficiency, you need to put your solar thermal panels on a south-facing roof at a 30-degree angle to the horizontal (up to 65 degrees will still work in the UK) and keep the panels away from shadows (trees, buildings, chimneys, etc). Solar panels can be heavy, so your roof must be strong enough to take their weight – especially if the panel is to be installed on top of existing tiles. Not all boilers are compatible with solar water heating – for example, if you have a combi boiler and you don’t have a hot water tank. So check what extra equipment you’ll need – and how much it will cost – if you are considering solar water heating. Some panels require regular checks of the unit and connections, or a wipe of the panel glass with mild detergent. Your installer should leave written details of any maintenance checks you should carry out from time to time. Bear in mind how difficult this can be when panels are up on your roof. Do Solar Work In Places That Gets Snow https://www.solarafter.com/do-solar-work-in-winter-or-in-places-that-gets-snow

Pros and cons of solar water heating Pros Solar water heating can provide you with about a third of your hot water needs You could save between £55 and £95 per year on your fuel bills Systems need little maintenance and the costs of it are very low Most solar water-heating systems come with a five to 10-year warranty Lowers your carbon footprint Cons You'll still need a boiler or immersion heater to make the water hotter, or provide hot water when solar energy isn't available Not all boilers are compatible with solar water heating Solar thermal panels cost more to install than conventional electric and gas-heating systems How to choose a solar water heating system When choosing a solar water-heating system, you'll need to consider four major factors: your average hot water use the area of south-facing roof available your existing water heating system your budget.

You'll need roughly one square metre of panel area per person in the household. Each metre of panel area will need between 30 and 60 litres of water-tank volume. If you use a less-efficient panel (such as flat-plate solar thermal panels), you'll need to cover a larger area than if you use a more efficient one, such as evacuated tubes. You'll also need to select system components – such as a hot water cylinder, controls and pipe work – and choose the location for your solar panels, considering shade, pipe runs, roof pitch and future access. Finding a good solar panel company — things to look out for You'll need to hire a professional to install your solar water-heating system. There are plenty of solar panel installers out there, so we recommend that you always collect a range of quotes to compare. Watch out for dodgy sales tactics, salespeople putting you under pressure to buy on the spot, and exaggerated financial savings.

We recommend you do your own research before inviting a company into your home. You should only use installers and products that are certified by the Microgeneration Certification Scheme (MCS), then compare the estimates of costs and savings you're given by salespeople against other sources of advice. You can search for a certified installer on the Microgeneration Certification Scheme website. Your solar water heating system must be installed by an MCS-certified installer to be eligible for payments under the Renewable Heat Incentive (RHI). You must also own the system. Which? Trusted Traders will help you find a trustworthy local solar panel installer. What you need to know about solar thermal panel installation A solar water-heating system involves pipe work, a thermostat and a hot water cylinder. Some also have a drainback system to drain water from inside the solar panel when the pump is switched off. You can add solar thermal panels to most existing hot-water systems. However, you'll usually need to add an additional cylinder for pre-heated water or change your existing cylinder for one with a twin coil. It's difficult to use a solar water-heating system with a combi boiler. This is because combi boilers heat water directly from the mains water supply and don't have a tank; solar water-heating systems supply warm, low-pressure water. Some new combi boilers do accept pre-heated water, so check with the manufacturer. To find out which boilers are the most reliable, take a look at our boiler reviews. can i buy solar panels and install myself https://www.solarafter.com/can-i-buy-solar-panels-and-install-myself

How to get the most from your solar thermal panels Before you install solar water heating, try to reduce the amount of hot water you use, to see if you can reduce costs without it. Or make the most from your solar hot-water system by following these tips: Use as much hot water as possible from the solar-heated supply, rather than heating up in an appliance using electricity. For example, fit a mixer shower (rather than electric) and check whether any ‘hot-fill’ appliances (which could include your washing machine) can take water from your solar system. Consider changing your behaviour to use more hot water in the evenings – in showers, baths and washing-up. This is when water will be hottest, as it's had most time to heat up. Ensure your back-up system is set up to switch on at the right time. Before you installed solar water heating, it was probably set to give you a full tank of hot water in the morning. But if you don’t change it, your panels will have nothing to heat during the day. Insulate your pipes and water tank to make your system more efficient. Follow your installer’s advice on how to set the hot water controls to get the most from your system. You should also make sure that you carry out any maintenance checks from time to time to make sure the system is working efficiently.

Your installer should leave written details of these. The most important thing to check for is leaks. If your system leaks antifreeze, you will probably be able to smell it – contact your installer. During the lifespan of your panels, the anti-freeze may need replacing or topping up. This costs around £100. Your installer may specify that your system needs checking by an accredited professional every few years. They will also check the pump. These last for around 10 years and cost around £90 to replace. Do I need planning permission for solar thermal panels? You don't need planning permission for most domestic solar water-heating systems in the UK, as long as they aren’t too big. But exceptions apply for listed buildings, buildings in conservation areas and World Heritage Sites. If this applies to you, contact your council to see whether you need to apply for planning permission for your solar panels.

How to choose a water heater

Things you should consider when buying a Geyser | Water Heater

Types of water heaters available in the market

Safety Components of water Heater

Key aspects to consider when choosing a water heater

1) Types of water heaters available in the market:

Solar Water Heater: Solar water heater works on the principle of converting sun rays into heat for water heating purposes using FPC (Flat plate collectors) or ETC (Evacuated tube collectors). The key methodology used is black body absorption. Solar water heaters are an eco-friendly and green approach to water heating. Water is heated using natural sun rays and can be used by the entire family. Many state governments also give a rebate on electricity charges on households that have installed solar products in their houses. The payback for the investment in a solar water heater works out to around 2 to 3 years. The various capacities available are 100, 150, 200, 250, 300 and 500 LPD (Litres Per Day).

Electrical water heater: The most common type of water heater is the one that uses electricity as its energy input. The voltage used for a water heater is 220v to 240v but few are 110/120v. The wattage rating becomes critical for comparing various variants.

Gas Water heater: The gas water heater is also known as an instant water heater. This takes gas as an input and can instantaneously increase and decrease the temperature.

Way of Installation:

Vertical Water Heaters: For Vertical Water Heater vertical space is needed. While the price of vertical water heater may be cheaper than the horizontal option, the aesthetics look is not as good as compared to the horizontal water heater. The vertical water heater nonetheless has good efficiency and is easy to install.

Horizontal Water Heaters: Horizontal water heaters are space-efficient and can fit above the false ceiling. They come with options of right and left water inlets and one needs to be careful when purchasing horizontal water heaters. Horizontal water heaters are a popular option.

Best brands available:

Havells Water Heater

Jaquar Water Heater

AO Smith Water Heater

V-Guard Water Heater

2) Safety Components Of Water Heater:

Human skin can take water temperature up to 30 to 40 degrees. Safety aspects of the water heater become a very important consideration. The key safety elements to consider are as follows:

Thermostat:

The thermostat regulates temperature by cutting power supply beyond a set temperature. It works as a temperature sensor. When the sensor is heated, the liquid medium expands and break the circuit.

Thermal cut-out:

In case of the thermostat malfunctions, the thermal cut-out comes into play and cuts off the complete power supply when the temperature goes beyond 88 degrees. The water heater employs a high-temperature limit protection switch which can be reset by manual operation. The switch rapidly cuts off the phase line and neutral line simultaneously to guarantee safety.

MFSV: Multi- Function Safety Valve

This comes into play when there is a leakage of the water heater. It occurs due to build up of pressure inside the water tank. There are 4 functions performed:

a) Pressure Release Valve: When the pressure is more the 8bar pressure, release valve will help to release the pressure using the spring system.

b) Non-Return Valve: This avoids the hot water to seep into the cold water line.

c) Anti -Vacuum Valve: When there is no water in the overhead tank and water heater, there will be a vacuum generation inside the tank and it will cause harm to the tank. Anti-vacuum valve will help to release the vacuum.

d) Drain Valve: This is useful at the time of maintenance to remove the water from the water tank.

Earth leakage circuit breaker (ELCB)

This helps in protecting against short circuits. It stops the electricity supply in case any unwanted event happens, like a short circuit or high voltage and protects the geyser. The electricity supply can be started manually by using a reset switch. It works in two modes:- 1) Voltage earth leakage circuit breaker & 2) Current earth leakage circuit breaker.

3) Key aspects to consider when choosing a water heater:

The following are the key aspects, one should look for when purchasing a water heater for one’s home.

Water Heater Capacity

The capacity of the water heater starts from 1 liter and can go upwards of 100 liters. The application and water heater type are elaborated in the table below:

Capacity

Electrical, Solar Water heater

200 ltr, 300 ltr, 400 ltr, 500 ltr

Centralized geyser for more than one bathroom available in Jaquar

Electrical and solar water heater

Poly Urethane Form (PUF)

CFC free thicker PUF insulation offers complete protection against radiant heat loss, reduces energy consumption and provides higher energy efficiency. Check if the water heater has good PUF insulation before buying.

Tank material:

Regular water heater tanks have a thickness of 1.5 mm. Better quality tanks will have 2 mm thickness which is made up of mild steel. 1.5 mm thickness tanks will be priced lower compared to 2 mm thickness.

Anode rod: The magnesium anode rod is also known as a sacrificial anode. It protects and saves the tank from electrochemical reactions during water heating.

More active than the base metal and easily reacts with different water salts/chemicals.

It helps in protecting the MS tank from corrosion and increases the life of the tank.

Rod replacement is done based on the hardness of the water. When the water is extremely hard, the anode rod has to be replaced within one to three years.

Tank corrosion protection coating

Since the water tank will be in contact with hot water for a long period of time, the tank interiors and the heating element can get corroded. Many modern water heaters provide for a glass coating to provide protection against scaling and corrosion. A smooth glass surface ensures a uniform layer to the inner side of the tank and over joints. It provides protection against leakages and premature tank failure.

Water pressure handling in high rise buildings

The water pressure can become very high in multi-storeyed buildings. The water heaters in such buildings need to be capable of handling this high water pressure. Only some water heaters are suitable for such high rise buildings.

ISI mark

The Bureau of Energy Efficiency is an agency of the Government of India, which gives a rating on a 5-star scale for all electrical products, based on the electrical efficiency of the water heater.

One of the water heaters which has a 5-star rating is “ELENA PRIME” from Jaquar.

There are various brands of water heater which have a 4-star rating in the Indian market such as Havells, Jaquar & AO Smith, etc.

Warranty for water heater

The warranty for the water heater is as follows:

Number of years

Material warranty

1 yr min – 7 yr max

Steel container (Tank)

1 yr min – 4 yr max

Heating element

1 yr min – 2 yr max

FAQs related to Solar Water Heater System in India

Here is the list of some of the frequently asked questions related to Solar Water Heater.

 1.       What is a solar water heater?

Available with different names in the market viz. Solar Water Heater, Solar water heating systems, Domestic solar water heaters, Solar Gyser, etc., it is the most effective way to generate hot water with the minimum impact on the environment. By collecting solar energy, solar water heater gives hot water as output. Utilization of freely available sunshine makes it cost-effective, pollutionless, eco-friendly and sustainable.

 2.       What are the major components of the solar water heater?

Basically, Solar Water Heater System consists of three major components: Heat Collector, Storage tank and connecting Pipes. Earlier models couldn’t work at freezing temperature, very hot climate or cloudy day but nowadays, technology up-gradation has made it possible to work effectively even at unfavorable climatic conditions.

 3.       What are the types of solar heat collectors used in a solar water heater?

As the name suggests, heat collectors are the component that collects heat from the sunshine. These are a vital component in any solar heating system. Basically, there is three types of solar collectors that are predominantly used for residential purposes.

 Flate Plate Collector

Evacuated tube Collector

Integral Collector-Storage System

 4.       What are Flat Plate, Solar heat collectors?

These are the most fundamental type of solar collector that has been used since the beginning. The basic principle of this collectors is: the sun heats a dark flat surface which collects the maximum possible heat and then transfers it to the water. The main components of Flat plat collector are as follow:

Black surface  - It absorbs the heat from incident solar radiation.

Glazing cover – It is a transparent layer that transmits radiation to the absorber, and also protects the heat loss by radiation or convection.

Circulating Tubes: These tubes contain the heating fluid to transfer heat from the collector for meeting the end purpose.

Support Structure

Insulation cover

Advantage:

Flat Plate collectors are simple and cheap.

Easy to manufacture, install and operate.

Less maintenance

Permanently fixed.

5.       What is the integral collector-storage system?

In this collector and storage are encased in a single unit. It contains single or multiple black painted tanks or collectors. Coldwater flows through the preheated collector tubes or tanks and gets heated. This is more utilizable in mid-freeze climatic regions. Mostly used for household applications.

 6.       What are evacuated tube collectors?

It contains parallel rows of transparent glass tubes. Each tube has an outer glass tube to receive maximum solar radiation and an inner metal tube which acts as a heat absorber attached to the fin. The fin is duly coated to restrict the heat loss and transfer maximum possible heat to the running fluid or water. These types of collectors are most frequently used across the globe. Also, it is the most used solar water heater in India both for residential and commercial purposes.

 7.       What are the things to remember while deciding the type of solar water heater to use?

Going solar is now a trend in India. If you are looking for purchasing a solar water heater, don’t follow the crowd. Instead you should focus on your own homework. Before selecting a solar water heater for your home or commercial purpose, you should consider the following things:

1.       Determine the correct cost and energy efficiency of the solar water heating system.

2.       Work on evaluating the solar heating potential of your site.

3.       Find out the correct system size

4.       Consider the rebates, discounts or available subsidy.

 8.       How to determine the efficiency of the solar water heating system?

For determining  the efficiency of the solar water heater, there are two indices used worldwide, also relevant in India:

·         Solar Energy Factor

·         Solar Fraction

 ·         Solar Energy Factor: Solar Energy Factor is a mathematic formula to determine the efficiency of the system. It is the result of the division of energy obtained from the solar water heater system by the energy obtained by the electrical, gas or other conventional water heater. The higher the number, the more will be the efficiency of the system. Normally, it ranges from 1 to 11.  If it is 1, it means your solar water heater is performing equivalent to your previously used conventional one while 11 means your solar water heater is 11 times more efficient than the conventional one.

·         Solar Fraction: If you are using a conventional water heater as a backup, solar fraction gives up the value of the solar water heater in your overall obtained heat from the combined system. It ranges from 0 to 1. Normally, it is around 0.5 to 0.8. e.g. 0.5 SF means 50% of your heating demand is fulfilled by the sun.

 While selecting a solar water heater, one must choose a higher efficient one. If you are choosing a combined assembly, put the SF above than 50%.

 Also, the sole consideration of efficiency is not advisable. You must consider the overall cost of the system as well.

 Calculation of annual operational cost:

 Before making the final decision on the type of solar water heating system, you must consider the annual operational cost of the available options and compare them to have a detailed overview. It will help you in the evaluation of annual savings and also determine the payback period. While considering the efficiency, always opt for a lower operational period to minimize the payback period.

 For calculating the annual operational cost, follow these steps:

Step 1: Find out your requirements and size of the system.

Step 2: The Solar Energy Factor of the System

Step 3: Cost of the conventional system (Gas or electric)

Step 4: Perform the respective calculations for cost-saving.

 1.       If the conventional system is Gas based: Determine the unit fuel cost and put them in the formula:

 365 × 0.4105 ÷ SEF × Fuel Cost (therm) = estimated annual operating cost saving

 Unit fuel cost in therm. ( 1 therm = 1,00,000 BTU), (BTU = British Thermal Unit)

 2.       If the conventional system is electric geyser: Use this formula:

365 × 12.03 kWh/day ÷ SEF × Electricity Cost (kWh)= estimated annual operating cost saving

This formula is based on taking 250 liter/day as the water requirement.

 Cost comparison and payback period:

After calculating the overall operational cost of the available options, compare the cost with the conventional water heater or geyser and determine the overall payback period. You can use the following table for easier comparison.

   Model

Installation  Cost

SEF

Annual  Operational Cost

Model A

   Model B  (more efficient)

   Additional  Cost of Model B

  =Price of B-  Price of A

Additional  Annual Cost Saving (Model B)

  =Operational  Cost B- Operational cost A

Payback  Period (Model B)

  =Additional  Cost of B/Cost B’s Saving per year

 Also, consider the maintenance cost for a more detailed approach. Contact us for more detailed analyses.

9.       How to improve the efficiency of the solar water heater?

There are various energy saving and efficiency improvement tips to enhance the performance of your installed and duly maintained solar water heater system. Browse for the latest energy-saving strategies and devices which are more cost-effective to install with the heater.

Always monitor the working efficiency of the system. Make a record of it and analyze it in your free time. If it is not working satisfactorily, call your contractor and ask for any maintenance or repair, if required.

Solar technology is not new but evolving. Every day, new innovations are entering in the market. Stay updated for any new add-ons for improving the energy efficiency of your system.

 10.   What are the sizes of the solar water heater available in the market?

Presently, there are many brands and solar contractor in the Indian market that provides various size of the solar water heater. The size of the solar water heater depends on the hot water requirement and other factors that we have discussed previously. The size of the solar water heater available in market starts from 100 litre per day.

  11.   How to find out the correct size of the solar water heating system?

The system size solely depends on the type of solar water heater system you have opted and the total requirement of the hot water. Here are the three types of solar water heating system. Follow the steps for sizing the system:

·         Calculate the overall hot water demand.

·         Select the type of system.

·         Find out the cumulative sum of area requirements of all the components.

 Let’s have a look at the sizing of the solar water system on the basis of their type:

Sizing the tankless or direct system: Tankless system or direct system means that the hot water is directly transferred to the end-user without hauling at storage tank. For sizing such system, follow the steps:

·         Find out the flow rate of the hot water application.

For finding this, determine the flow rate at individual outlet points. For example, required flow rate at the taps, showers or another utility point. Find out their algebraic sum.

·         Find out the temperature rise

The temperature rise is the difference of the inlet cold water temperature and required hot water

On the basis of these two factors, the solar water heater provider will suggest a suitable size for you.

 Sizing solar water heater system: In this, the overall collector area and storage capacity is calculated to determine the overall size of the system. After calculating the water requirement, follow these steps:

·         Collector Area: For the first two family members, normally a collector area of 20 to 25 square feet is suggested. For every additional member, collector area of approximately 8 to 10 square feet is added to the previous one. It again depends on location and its solar resources.

·         Storage Volume: A storage volume of 150litre is recommended for a small family. It increases with an increase in number of members of family. A medium storage tank of 250 liters is enough for 5 to 7 members.

 Sizing storage or heat pump type solar water heater: If you are thinking of an active solar water heater, calculate the area requirement of heat pumps and other plumbing components.

 The type of system, water requirement, storage requirement, and peak demand collectively gives the size of the system you needed.

 12. How much does it cost to install a solar water heater?

The cost of the system depends on various factors. Some of the factors are as follow:

·         Type of the system

·         Size of the system]

·         System Brand name

·         Associated warranty and guarantee

·         Free Maintenance period

·         The effective life span of the system

·         The efficiency of the system

·         Assured performance of the system

·         Add-Ons with system

·         Monitoring units or other additional equipment with the system.

 The approximate cost of the system has been enlisted in the following table. It may vary as per the trend and market demand.

 Overall Capacity of the system  (liters per day)

  13.   Which solar water heater is best?

All are good, depends what you require and need.

 ·         Evacuated tube collector systems are fragile in nature as they contain glass. Thus require smooth handling and care. These systems work satisfactorily in the colder regions even at sub-zero temperatures. If there is much salt content in the water, it gets deposited inside the tube. Therefore, tubes are required to cleansed properly after specific time period.

 ·         Flate Plate Collector system has a longer effective life as they are metallic, but they are expensive than the evacuated tube collector system. If there is much salt content in water, heat exchanger mechanism is required to avoid salt deposition which further adds to the cost of the system.

 ·         Passive solar water heater systems are preferable for small domestic or residential purposes while for larger commercial practices, an active system i.e. systems with additional pump is required.

 14.   How effective are solar water heaters?

The effectiveness and efficiency of solar water can be calculated from SEF (Solar Energy Factor) where SEF is Solar Energy Factor is a mathematic formula to determine the efficiency of the system. It is the result of the division of energy obtained from the solar water heater system by the energy obtained by the electrical, gas or other conventional water heater. The higher the number more will be the efficiency of the system. Normally, it ranges from 1 to 11.  If it is 1, it means your solar water heater is performing equivalent to your previously used conventional one while 11 means your solar water heater is 11 times more efficient than the conventional one.

On the basis of types of solar water heating system and its operation, you can calculate is effectiveness.

 15.   Do solar hot water systems save money?

Of course, the solar hot water system saves money.

If you compare the operational cost of a conventional heater and solar water heater, it is much lesser for solar water heater. Though the one-time investment cost of solar water heater is higher than the conventional heater, you are saving a lot in the longer run. If you break down the cost with respect to the overall operational period, solar water heater is a worthy investment.

 26.   What are the advantages and disadvantages of solar water heater?

Each type of solar water heater has its own advantages and disadvantages. Here are some:

 Advantages of Direct Circulation System

 ·         Simple and Reliable: The direct circulation system is simple and more reliable. The concept is simple, less maintenance, no additional fluid, and lesser energy loss make it more reliable.

 ·         Affordable: It requires lesser plumbing components, moving parts, and labor which makes it less expensive than the indirect one.

 Disadvantage of direct circulation system

 ·         Not efficient in very cold weather: In conditions of severe cold, when the temperature goes in negative, plain water gets freeze and can even burst the plumbing components. Thus, this type of system is not applicable at all locations, at all temperatures.

 ·         Not efficient for multiple heating needs: If you are looking for heating your two pools of water from the same system, it is not efficient. Multiple purposes mean multiple heaters.

 Advantage of the indirect circulation system

 ·         More efficient in a cold climate: As in this type of system either circulating fluid is used as a solar collector or it is mixed with water which further lowers the freezing point makes this system more efficient for such weather conditions.

 ·         Suitable for multiple purposes: Hear can be exchanged to multiple arrays of water make this system suitable for multiple purposes.

 Disadvantages of the indirect circulation system

 ·         Less Efficient: Because of the involvement of the heat exchange phenomenon, a great amount of heat is lost, make this system less efficient than another type.

 ·         Expensive: More plumbing components, additional fluid, and the setup take along additional cost which makes the entire system expensive.

  Advantages of the integral collector storage system

 ·         Simple mechanism, easy installation, and operation: Being a passive system, this type of solar heater doesn’t require additional pumps or electronic control. Lesser components make the overall cost cheaper. Moreover, less maintenance is required.

·         Cheaper alternative: It is the cheapest among the other types of solar water heater and most preferable for any DIY projects where homeowners can install their own built solar water heater with minimum cost.

Disadvantages of the integral collector storage system

 ·         Low performance and efficiency: performance and efficiency are very low. You can’t simply rely on such kinds of heaters. Additional backup is required.

·         More weight: Due to the presence of heavy collector tube, the weight of this type of heater is cumulative sum of water, collector tube, storage tank and some add Ons. So, mostly they are mounted on ground. For roof mounting, additional supporting structure is required.

·         Not workable at the freezing point: This type of heaters doesn’t work satisfactorily at freezing point or on a cloudy day. However, recent design innovations have made it possible in new versions of ICS system.

·         More Heat loss: The collector also acts as a water storage unit in this type of system. For avoiding more heat loss, double or triple glazing layers have been provided on the tubes which further add ons to the weight of the system. Still, there is considerable energy loss in this system.

 Advantage of Thermosyphon system

 ·         Highly reliable: these types of systems are most widely used because of their reliability, good performance, and efficiency.

·         Cost-effective: Being a passive system, it requires lesser component than the active one. Thus, it is more cost-effective than active systems.

·         Less Maintenance: It involves lesser maintenance and operational cost. Thus, a faster cost breakdown can be achieved.

 Disadvantages of Thermosyphon system

 ·      Freezing point operation: Thermosyphon system doesn’t work properly at the freezing point which makes is unapplicable for cold prone regions. For such locations, additional fluid is required to use either to mix with water or as a collector fluid.

·      Multipurpose uses: For multipurpose use, separate heaters are required which makes it a costlier alternative for multipurpose applications.

 27.   What are the maintenance guidelines of a solar water heater?

 ·      Passive systems require lesser maintenance while the active system needs more. If you are opting for the second category, duly discuss the maintenance and operational guidelines with the service provider and ask for the maintenance manual.

·      Plumbing and other components require the same maintenance as the conventional system.

·      Glazing of the collectors is required to be cleansed in dry climate where rainwater is no option for natural cleansing.

·      Regular maintenance is required every 3-5 years by certified service providers. If your system has electric components, typically in 10 years, you will need to replace the parts.

Also, check the following:

·         For ETC, glass tubes can break. Therefore, you may have to provide occasional replacement

·         Remove the scaling or deposits regularly. If there is much hardness in the water, acid can be used to clean the collector.

·         If your outer system is painted, you may have to re-paint it every 2-3 years to prevent the system from corrosion.

·         Occasional leakages or other issues need to be repaired periodically by local plumber or service providers.

 28.   How to hire a solar water heater contractor or service provider?

Q- What is the approximate cost of Solar Water Heater?

A- Cost of Solar Water Heater depends on size and type of system installed. Smallest size of a system is 100 liter per day, which means that it can deliver 100 litres of hot water in a day at 60 c. A 150 lpd capacity system is sufficient for a family of 3-4 members and it may cost rs. 15,000 to rs.22,000 in plains depending on the type of system. In hilly & N-E region, the cost may be 15% to 20% more.

The system cost only includes hot water tank and does not include the cost of cold water tank, and its stand which is required if overhead tank is not installed in a house/ building. Cost of hot water insulated pipe line may be extra if number of bathrooms is more than one. additional cost towards all these components may increase by 10 to 20%. The cost, however, does not increase linearly with increase in capacity; rather it comes down proportionately as we go for higher capacity system.

Q- Is there any subsidy available from government?

A- No, the subsidy scheme has been discontinued w.e.f 12.08.2014 onwards.

Q- What happens on cloudy/rainy day? Do i still get hot water?

A- On cloudy days also, if it is for a day or two, you still get warm water as water gets heated due to diffused radiation available in the atmosphere. The system, however, is either connected to an electric geyser in the house or an electrical back-up is provided in the storage tank of the system which is switched on when water is not sufficiently hot. so, you get hot water all the time even on rainy days.

Q- How do i assure that a good quality system is installed at my house?

A- Ministry has laid down some minimum technical requirements for installation of solar water heating systems in the field. These have been made mandatory for manufacturers and suppliers and are available on mnre website: www.mnre.gov.in. These requirements are have been prepared in such a way that even a lay man can also check them and ensure that those are being adhered to by the manufacturers/suppliers. In case any manufacturer is found not sticking to these requirements, he may be blacklisted if informed to the ministry.

Q- Are there any maintenance requirements?

A- Domestic solar water heating system do not need significant maintenance requirements. occasional leakages in the plumbing could be easily repaired by common plumbers. In case quality of water is hard, scale deposition in the collectors may result over the years. this may require de-scaling with acids for which it is best to contact the suppliers. broken glass may also have to be replaced by the suppliers. If outside exposed surfaces are painted, the paint may have to be redone every 2-3 years to prevent corrosion of the surfaces.
