Heat Pump Sump Heat
My American Standard heat pump has a sump heater that runs quite a bit. I turned the unit off at the breaker last spring. There are many cold days & nights when I don’t need the heat pump. I’m wondering if there are any issues leaving it off? Should I turn it on xx hours before I need the heat pump? The service manual says the sump heat is ON When outdoor temp is below 80F and compressor dome temp is less than the outdoor ambient temp. That seems pretty wasteful.
