Item Description

SR961s/SR962s Solar Water Heater Working Station

Intelligent and Efficient Solar Water Heater Control

The SR961s/SR962s solar water heater working station utilizes an efficient design and intelligent controller for high performance control of your solar water heater system. The station comes complete with a pressure gauge, charging/draining ports which utilize a check valve to ensure one way flow during charging/operation, a connection for an expansion tank, efficient and reliable wilo pump (made in Germany), insulation cover and a sleek metal enclosure.

Enjoy years of operation with efficient control of the circulation pump. This unit consumes less than 4 watts during operation. (The national average cost to operate this unit is no more than 30 cents a month!) Digital speed control of the pump allows for the most efficient use of your pump's electrical power. When high pumping speeds are needed, it can circulate quickly to obtain heat. When heating is average, the pump levels out to a nice slow speed for efficient and even operation.

The SR962s model has a two pipe system. The 2nd pipe is for the return from the solar collector, which has an additional sensor for detecting the temperature of the fluid returning from the collector.
