Hi Kent, do you mean a hydronic coil (heat exchanger) in their furnace or air handler to transfer heat into their forced air system? And this is heated by a boiler or water heater?
Hi Toby,
You are correct, it will be a hot water coil in the air exchanger as back up to the ASHP. So far we are having a hard time finding local contractors that are familiar with either set up.
This Gentlemen may be able to help:
