FAQs

1. How to choose a solar water heater in India?

Since solar water heaters don’t come for cheap, you must keep certain factors in mind when buying them. You need to buy one depending on how much sunlight you get in your area. If you are from a chilly hill station that doesn’t see the sunrays half the year, there is no point buying a solar heater. 

That said, when buying one, it is extremely important that you check for a few things. Check the capacity, material, and the overall build quality of the unit. If it feels flimsy, there is no point buying it at all. The best thing that you need to keep in mind is to ensure that you do keep an eye out on the types too.

There are two variants – the flat plate collector and the evacuated tube collector. Even though the latter costs more, it is a far better option than the first one. But, if you have budget constraints, opt for the first variant.

2. What should you check before buying a solar water heater?

It doesn’t matter if you are buying the solar heater for your home or your office, there are a few things that you need to check from your part before making the purchase. One of the most common factors is the source of sunlight. You need to ensure that you have a direct source of sunlight pouring in that spot throughout the year.

You also need to ensure that the place you want to install the solar heater in should be sturdy enough to hold the stands and the panels without any hassle at all. This is a necessity. The last thing you want is to cause negative impacts on your building’s construction.

3. How much capacity is enough?

When buying a solar water heater, it is likely for you to be confused about the capacity of the heater. Don’t worry though. It depends on the number of people who would access hot water. If you have only 2 people in your home, the 100 liters capacity would likely suffice.

But, in case you have more, it is better that you enhance the capacity too. This is all dependent on how much water you will access and how much water you will need to stay hot for the other people to use at home.

4. Does solar water heater require maintenance?

Of course, they do. Some of the solar water heaters don’t require very frequent maintenance but you need to keep an eye out on them every year or every other year. If the material and construction of the unit are good, likely, you wouldn’t have to worry about anything at all. But, in case you have settled for a cheaper variant, we would suggest that you assess your investments because these require a lot of maintenance now and then.

5. Is it safe to buy a solar water heater online?

Yes, it is completely safe for you to buy the solar water heater online. They do come in the best packaging, so there is no need for you to worry about the quality of the unit. But, buying it online means that you’d have to hire someone from outside for the installation, which can be a hassle sometimes.
