WoodMaster exclusives:

Round chamber design provides optimum internal air movement and water circulation for even heat transfer and more efficient burn. This design also offers:

  • Forty percent fewer seams than a square box, for less chance of cracking or leaking and minimal pitting
  • No dead spots, so creosote doesn't build up
  • Digital Electronic Temperature Control  for operating temperature settings, blower, reset, water level indicator and nightlight in an easy-to-read display.


Each WoodMaster wood furnace is installed outdoors, 25 to 400 feet from the home or structure(s) that it will heat. A core fire box is surrounded by a water jacket. The fire warms water to its optimal heating temperature, maintained by automatic controls. The warm water moves through insulated underground piping into the home’s heat exchangers and heating system. Inside, you control the temperature with your thermostat.
