    Central Furnaces in Duluth

    A safe, efficient outdoor wood furnace can provide 100% of your heating needs. Central Boiler manufactures and distributes the Classic and E-Classic outdoor wood furnaces. These outdoor wood-fired hydronic heaters can heat multiple buildings, hot tubs, pools, greenhouses, domestic water and more. While burning a wood stove indoors can mean ash and smoke in your home, there is an alternative—a Central Boiler outdoor wood furnace. It eliminates the problems associated with indoor burning and allows you to get even more benefits from wood heat. Central Boiler outdoor wood furnaces can improve the indoor environment in your home or business by removing smoke and ash as a result of indoor burning, while eliminating the time-consuming chore of tending a traditional wood stove.
