My question is this: Would a GHP of the size
needed to heat/cool the house produce enough extra hot water to keep a 2
car
garage floor heated in the winter via piping runs in the cement, or would
I
have to upsize the GHP unit to handle both chores?
Thanks for any input!



Of course you have to upsize if the original pump is designed just for the
house. Look at insulating the floor or you will have to upgrade quite a
bit.
