FordGuy,

The amount of heat a wood boiler puts out is HUGE. And the temp is a lot hotter too. The reason for the small temp drop you quote (1-2 F) is because the wood boiler pipes heat up the ground.

You have a much smaller capacity and temperature with the heat pump.

Now you know, do what you think is best. But you need pipes about 4 feet down.

Lastly, the risk of a propane issue is very, very small. Yes, it is a "risk", but one that many on this forum would not worry about. Remember the very small amount of propane that is in a heat pump - tiny.

Caveat emptor!
