How to select the best solar water heater for your home?

Choosing a right solar geyser can be a tedious task, considering so many models are available in the market. However, there are certain factors that you must keep in mind while choosing a solar water heater. They are:

Know the type: FPC vs ETC

There are generally two types of solar water heaters: Flat Plate Collector (FPC) and Evacuated Tube Collector (ETC).

FPCs are metallic whereas ETCs use glass tubes. The major difference lies in the efficiency of both these heaters. ETC is way more efficient when it comes to the production of heat and that is why it is the best option if you live in chilly or rainy region. There is also less heat loss in ETC.

When it comes to cost, FPC is cheaper than ETC. Due to its metallic structure, FPC is stronger than ETC and thus, lasts long. I’d personally suggest you to go for ETC solar water heater because it has great performance.

Brand:

Brand plays a great role while buying a product. Always go for a certified brand that is trusted amongst the customers for its quality and after sale services. Also, a good brand also ensures great performance and will easily last you several years.

Some of the top solar water heater brands in India are:

  • Racold
  • Supreme
  • GreenLife
  • V1
  • V-Guard

Your location:

Your geographical location is also important when it comes to selecting the right solar water heater. If you like in a sunny area that receives sufficient solar radiations then you can opt for FPC. It is inexpensive. However, if you live in a region that receives less sunlight, then you should go for ETC. Although it is expensive but it is highly effective.

Liters per day (LPD):

While buying a solar geyser, it is important that you keep your family size and number of bathroom connections in mind. Go for the tank capacity that is sufficient for your family. If you have a small family then 150 – 250 LPD would be fine for you. For a big family, 300 or more LPD is great option.

Installation and after sale service:

Find out if the company provides installation service at the place where you live. For example, some of the brands above offer installation service only in a city like Bangalore, Delhi, Gujarat, or Goa. If not, contact a local technician for installing your solar water heater.

Also, make sure you go through the user manual properly. Before making the purchase, enquire about the after sale service provided by the company along with their policies. This will save you from a lot of inconvenience later.

Customer reviews:

Going through customer reviews can help you to a great extent to get a clearer picture about what product you should go for. It also helps you understand both the pros and cons of a product and thus, make a better choice.

However, for a solar water heater you will find less reviews online because of the non availability of the products and again solar geyser is a new thing and it is not widely used among the households in India. Most people preferred the electric geysers because of the cost and lack of awareness.

Warranty:

While buying a solar geyser, make sure it has a good warranty period. Generally, water solar heaters come with at least 5 years warranty, although it can vary from company to company. If you want to have the best experience, be considerate about the warranty offered by the company. You can even enquire about other policies as well.

Climate and solar water heater efficiency: will it work at my place?

As I have already mentioned before, the climate or the geographical location does affect the output of a solar water heater. If your geographical location is close to the equator, then solar water heaters are just perfect for you. It will only increase the efficiency of the heat production. Even with a small or passive system, you will get incredible amount of heat.

However, for those who live in cold or rainy areas, installing a solar water heat needs certain measure because such regions receive less amount of sunlight. In such situation, a large or active system is best. Go for an ETC solar water heater because it is highly efficient.

Apart from this, it is also important to monitor and prevent any potential freezing risk. So if you live in a cold region, always go for “drainback” tank model. You can also go for a system that comes with automatic temperature monitor feature in order to avoid any potential risk.

Solar water heater maintenance and cost

Once you have installed the solar water heater, it is suggested to get it maintained annually for better and smooth functioning. Scheduled maintenance is a great way to ensure long life of your device.

The maintenance of solar water heater generally includes cleaning, replacing and repairing different parts. The maintenance cost depends on various factors ranging from service provider to the condition of the solar water heater.

But it would hardly cost you much. The maintenance amount is very minimal as compared to the amount that you save on your bills due to solar water heater.
