Heat Pump Pressure Valves
Heat Pump Pressure Valves
(OP)
I have a heat pump with hot gas bypass, water cooled here in Southern Georgia. The manufacturer's literature explains that the compressor has two high/low pressure switches respectively. The one is supposed to be set to 30 PSI, the other at 400PSI. Am I correct in suspecting that 30 PSI to extremely low? These units operate on R-22.

At a certain low temperature the heat pump will generate insufficient heat and supplemental heat will be necessary, however, I don't know if this is the case where you live but where I reside in MA it will be necessary
