The SCWD compressor unit Internal Heat Recovery System contains a water high temperature
control. It is factory set to 140°F. The Heat Recovery System also contains a refrigerant low
temperature which is factory set at 130°F. Also, a freeze protection control is designed to operate the
circulating pump when water temperature drops to 40°F, in order to provide water circulation
independent of compressor operation.
The GSTE storage water heaters are available in 60, 80 and 119 US gallon capacities, all of which
have a 4.5 kW electric heating element, which provides the following recovery rates for increases in
water temperature.
