This is for my river place. It has a heat pump, which I rarely use in the winter (that's what the stove is for). I got an internet t-stat that lets me program from afar. In the winter, I keep the house at 42' when I'm not there. If I'm coming in, especially at night or with the wife/kids, 42' on arrival doesn't cut it, so I turn on the heat remotely to at least get it to 55' or so (it takes a LONG time for the stove to heat the place from 42' if it's cold outside!). The heat pump of course sucks in the cold weather, but will eventually warm the house (also takes a LONG time, but I can turn it on 12 hours or whatever before I'm arriving). The problem is/was that with that much of a differential between actual/set temp, and with the suckiness of the heat pump in the cold, the system wants to turn on the electric emergency strip heat until it gets up to temp. This it does far quicker than just using the pump, which basically will run constantly. I disabled the strip element, so now it only will use the heat pump. The question is: Am I better off running the strip heaters for a shorter period of time (at much higher energy consumption), or the heat pump using less energy/hour, but taking a much longer time?
