A HeatMasterss outdoor wood furnace can be installed into your home heating and hot water system easily and very effectively. A radiator can be installed in to the existing plenum of your furnace and a water to water heat exchanger can be used to heat your domestic hot water.


To heat the home or structure, the outdoor furnace pumps hot water indoors via insulated underground pipes. Once the water enters the structure, it travels through the traditional heating systems, including radiant baseboard, forced air furnace or radiant floor system and then circulates back to the furnace.


Heatmasterss outdoor furnaces come with easy access rear doors and ball valves on the furnace outlets making plumbing and maintenance quick and easy.  Insulated underground pipe enters the rear of the furnace through the floor and connects to the furnace outlets. The pump is installed on the supply outlet to push water to the building being heated. Electrical wiring and components are set up on the furnace for easy wiring and servicing.


The HeatMasterss system is perfect for garages, shops and other outbuildings. It will supply heat to an overhead forced air heating unit or in-floor heating allowing you to use the existing boiler as a backup.


A HeatMasterSS furnace is typically installed in your yard but may be installed in a shop, garage or outbuilding. Installing your furnace inside a building keeps you and your furnace outside of the elements. If installed in your yard it can be installed up to 300 feet away from the building or the structure you intend to heat. This creates a natural buffer to keep all noise, mess and risk of fire safely away from the areas you spend the most time.
