Active solar water heating systems require a circulator pump to transport heated water or heat exchange fluid from the collectors or absorbers to the tank where it is stored until required. Operating on variables such as temperature settings and sensor information, circulator pumps keep water moving as required by the system.
SolarTown carries solar hot water circulator pumps from reliable and efficient manufacturers. Circulator pumps can generally be purchased in several sizes depending on the capacity of your solar thermal system and the size of your storage tank. They can often be purchased together with temperature controllers or as part of a complete solar water heating kit.
