A Solar Water Heater might look like an expensive deal but if you buy the right one for yourself then it might help you in saving a lot of money on electricity. A Solar water heater isn’t always the best option. It has its advantages and its disadvantages. So do consider the following factors before you choose to buy one.
Purpose or Use
If you own a large establishment and want water heaters for your office building (or for a bunch of apartments) then go for Solar Water Heaters. They’ll help you save a large amount of money on power and you’ll recover their cost in no time. But make sure that you buy a highly effective solar water heater otherwise you might start receiving cold water after a little use.
And in case if you live in a tropical region where one rarely uses a water heater then don’t buy a solar water heater. They are quite costly when compared to electric water heaters. You will never be able to recover their cost.
Solar Water Heaters come in a wide range of prices. But they are generally more expensive when compared to electric water heaters. They might help you in saving money on electricity but their initial cost is high. So if you are permanent resident of a place and think that you’ll be using a solar water heater for a long time then go for it.
Solar Water Heaters have two types of heating systems:
- FPC (Flat Plate Collector): This system is made of metal and it is quite expensive. The Solar Water Heaters that have this system are more durable and have a longer life. But if you are using a FPC in a region where the temperature goes below zero then you might have to use expensive anti-freeze solutions to protect it.
- ETC (Evacuated Tube Collector): This system is cheaper but it is made of glass so it might easily get damaged. You might have to pay large amount of money on repair. And in case if your water supply provides you with salty water then you will have to use a heat exchanger to protect the heating capacity of this system.
Size and Capacity
Bigger Solar Water Heaters are more expensive. But at the same time they are also more efficient. If you want solar water heaters for extensive use then buying a bigger one will always be a better option than buying two small ones. You’ll save on both cost and efficiency.
A good Solar Water Heater might survive one or two cloudy days but never more than that. It will start giving cold water after that. If you want to avoid that then you can do two things. Either you can keep a spare Electric Water Heater for emergency purpose or you can buy a solar water heater that also works on electricity.
The heating of your Solar Water Heater directly depends upon the amount of sunlight it receives. It will be more effective if you live in a region that’s closer to the equator. But as you go farther from it, its heating capacity will decrease exponentially.
There are a lot of cheaper Solar Water Heaters that are available in the market. But make sure that you buy a branded one. Branded products are trustworthy and they offer better services. Beware of fake brands.
A warranty is an added assurance that the product you are buying is durable. If you encounter a nice branded Solar Water Heater that also offers a long warranty period, then go for it.
Most of the countries have a certification standard for such products. So make sure that the product you are buying is certified by your regional or national standards.
Ultimately it is the user that determines the final quality of the product. So do read the online user reviews about your product before buying it. Pay more attention to the reviews by certified reviewers.
