How Central Boiler outdoor furnaces work:
Simply put, Central Boiler outdoor furnaces burn wood or pellets to heat a jacket of water. The water is transferred via well-insulated piping called ThermoPEX from the furnace to your home or building. Once inside the water pipe is connected to your existing heating system. Water transfers its heat by direct circulation or by moving through one or more heat exchangers (or both) to interface with forced-air, radiant baseboards and radiators or radiant floor heating systems. This allows you normal thermostatic temperature control.
