We sell, deliver, install and service HeatMaster outdoor wood boilers ourselves, so you deal with the same people from start to finish.

Burning wood in the outdoor boiler heats the water around the fire box. That hot water runs through insulated underground lines to your house, garage or shop, and ties into the heat you already have: forced air, in-floor heat, radiators or baseboards. It can heat your domestic hot water, hot tub or pool too.
