Types of solar water heaters

Generally, solar water heaters are categorized into two types based on their installation methods. They are active systems and passive systems.

  • An active system circulates water within the tank with the help of pumps. Whereas, a passive system uses the seesaw technology meaning the warm water rises and the cool water sinks to the bottom to circulate hot water throughout the tank.
  • Active system solar water heaters are good in withstanding the pressure of overheating, as they have to overheat protection. On the other hand, passive solar water heaters are affordably priced but they don’t have overheating protection.

What to look for when purchasing a solar water heater for your home?

As you all know, a solar water heater is used to heat up the water by utilizing solar energy directly into its panels. They reduce electricity consumption and they are environment friendly as well.

In order to buy the best one, you need to know what to look for in a solar water heater before taking your wallet out.

Here’s a list of 7 items you need to consider before going for the purchase.

  • You need to determine whether you are going to use a solar water heater for either domestic or commercial purposes.
  • Generally, most solar water heaters function to their fullest potential when there is optimum sunlight. So if you want to enjoy hot water at all times, purchase a duel-power solar water heater.
  • Look at the solar absorption system. Usually, there are two different solar collection systems available namely, flat plate collectors and evacuated tube collectors. Do your due diligence before buying either of these.
  • Consider the location. If you are living on flat land, consider buying a passive heating system that will work really well for you. And if you are living in a hilly area, then an active heating system will be the best for your situation.
  • Consider your family size and tank capacity. This is obvious. If you have a large family, then go for more than a 200-litre tank capacity. And if you have a small family, then a 100-litre or a 200-litre tank will be the right one for you.
  • Type of tank. Always go for the tank that is built with stainless steel material and powerful PUF insulation. This will allow it to retain the warmth of the water inside the tank for a long time.
  • Your budget. This is the key aspect. Domestic solar water heaters are more affordable than commercial ones. But before purchasing any of these two types, you should keep the needs of your home in mind.
