Using air sourced heat pump with radiant

Steve Edelman

I'm wondering if anyone has any experienced using air sourced heat pumps with radiant?

A company called AquaSource makes a dx to water box (and I am sure there are others also) that hooks to a standard heat pump. So one gets hot water for heating and cool water (to the air handlers) for cooling. In my climate (Portland, Oregon) the winters are mild enough and electricity cheap enough that the cost per btu is almost half that of burning natural gas.

Has anyone ever used this product or any other similiar setup (ie air sourced heat pump) and if so how did it work out? I know there are plenty of systems out there using ground sourced heat pumps but I can't find much about using air sourced.

Thanks.
