My husband was really interested in an electric heat pump for our new house. He was talking to several co-workers at the steel mill and decided that he wanted the heat pump. I didn't know much about the heat pump at all just what he told me. So I thought I'll just leave that decision up to him. Our builder took care of all the details. They installed a Rheem Furnace and Air Conditioning / The Heat Pump. Our house was built in 2006. The Unit has been pretty efficient and maintenance free. We have a Braeburn model 1200 non-programmable 2 heat/1 cool heat pump thermostat. The thermostat is digital to set our temperature for rooms. There are up and down buttons. There is a switch for cool/off/heat/auxiliary. It has a white casing. So you pretty much just run the unit for your most pleasant environment temperature. You may not understand how the heat pump works. During warm weather, the heat pump is just like an air conditioner. It has an inside coil, an outside coil and a compressor. These move heat from the inside to the outside. In the winter it is reversed. The auxiliary heat will come on as needed. We find this whole unit to heat /cool our home effectively and efficiently. We are always looking for better ways to save money with heating/cooling. We added an additional wood stove to the basement for really cold days to keep the auxiliary and heat from running hardly at all which has saved tremendously on heating. I can't say enough about the air conditioning. It is absolutely wonderful! With the high prices of gas these days, we need to look for more affordable ways to heat and cool our homes.
