I am in the process of doing a major remodel. I live 20 miles north of Charleston, WV so temps are cold at times (today it is 9 deg). I have a 2 story house that is approx 3000 sft with each floor having approx 1500 sft. I want to use a heat pump with 2 wood stove inserts to help heat the house.
I have 2 seperate quotes on the heat pump systems. One guy is saying he would install 2 thermostats with 1 up and 1 down. The other guy says it would be best to put 2 on each level.
Downstairs has 4 bedrooms on one end of the house (where my 4 boys will be sleeping at night) and a large family room on the other end of the house. Ceilings downstairs are about 9 ft high.
Upstairs configuration has about 750 sft with cathedral ceilings on 1/2 of the house where the dining room, living room and kitchen is located. These rooms are seperated by a 8' normal ceiling for about 1/4 of the house and the remaining 1/4 house (my bedroom) has cathedral ceilings again (my bedroom).
The second guy would like to put 1 therm in 4 bedroom hallway, 1 in large family room, 1 in dining/living room, and 1 in my bedroom. The bottom floor has concrete floors where I will have carpet and the walls are cinder block with 2x4 studs w/ insulation. All upstairs is wood exterior walls. I would like to know what you all think is the best thing to do as far as the number of thermostats. Is it better to have more than 1 on each floor or does this create problems with dampers, etc...?
