Thanks for the reply. This is my trade or at least it used to be before getting a goverment job. I do remember there was a cut off point that for the amount of heat transfer and what the compressor was costing to run it was cheaper to just use heat strips. Remember that being in the mid twenties. You are the first person who has had the same mind set as myself. Everyone else is saying around 45 degrees. If I was trying to heat it for comfort I can understand their mind set a little better. Right now I only have a electric furnace but only using it to maintain 45 degrees when I'm not there really isn't to bad. It was when I first bought the place and didn't have wood burning stove it was costing a arm and leg. I will be using a multi stage stat. But I will still need a heat pump shut off. We have already had sub zero weather at night. What I really need is a way to use the heat pump to keep the space warmer and then let it cool down at night so the strips would run as much
The only problem is when we have really cold days I will using the heat strips instead of the heat pump. What I could do is use a outdoor stat which would switch to a different thermostat with a lower setting when temperature drops outside
Any thoughts on this?
