I recently received a request for assistance on an interesting project in Alaska. The owner was installing a floor-heating system that would be supplied from a propane-fired mod/con boiler as well as a cordwood gasification boiler.

The mod/con boiler would be installed in the house it would heat. The cordwood gasification boiler and its associated thermal storage tank would be installed in a well-insulated barn located about 100 feet from the house.
