We're currently remodeling and expanding our first floor. Our home has radiator heat. Our HVAC guy wants to creat a new two zone system, using the radiators upstairs but pulling them out on the first floor and using a heat pump attached to the new AC unit to heat the first floor. On the one hand, this would be great and we could remove the unseemly radiators.On the other, I'm afraid switching to electric heat will vastly increse my electric bill. Any tips? Suggestions? Insight? Anyone know any links that give the 101 on heat pumps? Many thanks!!
