Re: OT- Thermostat for heat pump... What is Supl.
Better yet, if you need the heating AND cooling capablities of a heat pump, go with a geothermal heat pump. Properly sized they will provide all the heat you need for a home. Plus they are more efficient than air-to-air heat pumps. The concern about feeling cold is true. They move air at 85 to 110 degrees where electric or gas furnace is probably around 140 degrees. Fast moving air creates a wind chill, so to prevent that in properly built heat pump homes, ductwork and registers are oversized and air velocity is decreased. The same or greater volume of air moves, just at a lot slower speed. At that point, heat pumps are very comfortable, and inexpensive to run.
