How an Outdoor Boiler Works

Outdoor wood burning boilers are installed outside your home, business place, barn or outbuilding from 15 to 500 feet away. Whether you have a forced-air, radiant baseboard or radiant floor heating system, they are designed to work with your pre-existing heating system. If the space you desire to heat does not have a current heating system you will be able to decide how the heat is circulated through your space. Wood boilers are designed with a central firebox and water jacket that circulates heat by using heated water pumped to your building through insulated pipes.

For those with in-floor, radiant heating, the hot water heated by a wood boiler will be sent through the in-floor tubes. This provides steady, consistent and controllable heat for your home or shop. For those with forced-air heating, a water-to-air heat exchanger will heat your home with the energy from the hot water. Whatever your heating system, you will be able to control the heat circulated through your home by a normal thermostat.
