It's illogical to compare the efficiencies of gas to heat pump systems because the way they produce heat is completely different. One directly burns fuel to produce heat, the other consumes energy only to move heat around. The source heat for heat pumps is essentially free. Thus calculating heat pump efficiencies will yield numbers well over 100%, something ...

The controlled AC outlet you linked to in the comment above seems like overkill unless you were intending to run all of them from one thermostat. I'd actually recommend putting all of them on individual thermostats so you can keep them in 3 different heating zones. Not only would this be much cheaper (the relays don't even include the thermostat), but it ...

I've been told that a properly sized heat pump should run almost non-stop during the days that the temperatures are the normal low for the season and area. Any lower than the normal seasonal lows would kick the strips on.

This might need to be confirmed by others, but the emergency/auxiliary heat is a subsystem of the heat pump that does not need to be turned on at all. I own a heat pump too with electric heat backup. It kicks on when the temps are below 30 degrees or the temp is raised to much manually, more than 2 degrees higher. Otherwise it does not come on. My bill for ...
