At Greenbuild: Solar Water Heating
February 1, 2010

SolPak is Rheem’s first all-inclusive active solar water heating system. It comes equipped with all components needed for installation: heat exchanger tank, collector panels, a controller, multispeed pump, thermal expansion tank and other essential items. Sensor wires measure the temperature at various points in the system and activate the pump to circulate the heated fluid from the collectors down to the tank and back until water is heated to the desired temperature.
