3 Active Solar Hot Water Heater Facts 3 Active Solar Hot Water Heater Facts
In places where heated water is not a luxury but a necessity, using an active solar hot water heater is a cost efficient and environment friendly alternative to electric powered water heaters.
Contrary to what most people think, most types of active solar hot eater heating systems do not run through solar power alone, they need electricity to run the circulator pump. However, the good news is that this type of heating system gets most of its power supply from the sun so you can save a lot of money on your electric bills.
How it Operates
An active solar hot water heater operated by pumping heated water directly to the collectors and back into the storage tank. Most types of solar water heaters have mounted on the roof of the house and it should only be pumped into the storage tank when the water inside the collector is hotter that the water inside the water tank. Compared to the passive water heating system, the active solar hot water heater is more tolerant to high water temperatures.
Since this type of system allows for active exchange of water between the collectors and the storage tank, you can put your storage tank away from the collectors without affecting the efficiency of the system.
Heat Control System
To facilitate efficient water exchange, you should use an electronically controlled pump with a reliable thermostat. This way, you can reduce the possibility of overheating or freezing the water inside the tank.
