Heat Pumps for Hydronic (forced-hot water) Radiator Heating Systems

Q:  For homes with existing hydronic (hot water) radiators, what do you recommend?  Is it possible to use air-source heat pumps to heat the water on those systems?  What about increasing the radiator sizes to operate with Lower water temperatures?

A: Yes you can do this. Daikin, Jaga and SpacePak all make air-sourced heat pumps designed especially for FHW systems. I think it will be a lot cheaper to use the existing radiators and leave the old furnace in place in case the heat pumps can’t keep the place warm in the middle of winter.
