With the cold weather I was hoping to hear of some experiences people have had with their heat pumps.
What kind of backup heat do you have? Are you using it? Is there some temperature where you just stop using the heat pump, or are you even consciously thinking about it?
Thanks!
Daikin, Mitsubishi say -13F.
You can switch on an aux heat source after that. Resistive, gas, wood. Most air handlers have optional resistive heat.
An air conditioner is a heat pump. Very little difference.
It’s not quite that simple; the output drops as the temperature gets really cold, so auxiliary heat likely kicks in before the heat pump actually shuts off. They’re still great, efficient technology, but when considering auxiliary heating needs and system sizing, the reduced output at low temperatures needs to be considered.
