Sorry I confused people - I was responding (in my mind) to the person who posted about whether or not you could/should use setback thermostats with electric heat pumps.
I have gas forced air here. That's what they were putting in when we bought (2006). It came with a setback thermostat and we use it. I love it.
Now TV is building exclusively all-electric homes with heat pumps. According to what I heard (and what I was told 30 years ago in Ohio when I had an electric heat pump in an all-electric home for a short time) on the radio yesterday, one should not adjust an electric heat pump thermostat more than 2 degrees at a time as it is inefficient and costs more to do so. i.e., you could use a setback thermostat, but you should only adjust it up or down by no more than 2 degrees at a time.
If you wanted it cooler at night, could adjust it (the thermostat for an electric heat pump) down gradually with maybe 2 hour intervals in between temp changes. I hope this is a clearer explanation of what I was attempting to explain.
