Hardy outdoor wood furnaces are made to heat the inside of a home, not an outdoor space. A Hardy outdoor wood-fired furnace is placed 10 to 100 feet from the house and pumps heat to the indoors via the structure's existing central duct system or hydronic heating system.
Hardy wood-fired furnaces provide residential heat and household hot water while keeping smoke, ash and soot away from inside rooms. Hardy outdoor furnaces can be used to heat homes, greenhouses, workshops, dairy barns and swimming pools. Hardy furnaces are available in styles that burn cord wood, wood pellets or coal, as of March 2015. All Hardy heaters are made in the U.S.A. and are covered by a 25-year limited warranty.
