Central Boiler Wood Furnaces

Wood Is the Most Efficient Way to Heat

How a Central Boiler Outdoor Wood Furnace Works

A Central Boiler outdoor wood furnace burns wood to heat water. The heated water is circulated through insulated underground pipes called ThermoPEX to the buildings being heated. The heated water can transfer its heat energy by direct circulation or by moving through one or more heat exchangers, or both.

Circulation

The furnace contains water that surrounds the furnace firebox and heat exchanger. This heated water is circulated to buildings through insulated underground pipes which is an efficient way to move heat over distances.

Integration

Central Boiler outdoor wood furnaces are designed to work with your existing heating system. Water-to-air or water-to-water heat exchangers or direct circulation conveys the heat into the structure's forced-air furnace, radiant baseboard, or radiant floor heating system. This allows you to control the heat simply with your thermostat.

Unlimited Hot Water

When you install a heat exchanger on your domestic water heater, you can enjoy unlimited hot water and savings when you turn your water heater off.

Heat Multiple Buildings

Unlike an indoor wood stove, a Central Boiler outdoor wood furnace can heat multiple buildings such as a house, garage, workshop, shed, greenhouse, or barn. It can even be used to heat a swimming pool or hot tub. 

Location

The Central Boiler outdoor wood furnace is located outside, typically 30 to 200 feet (but as far as 500 feet) away.

Installation Is a Breeze

Connect the piping and heat exchangers to your existing heating system and the Classic Edge is ready to go to work.
