What is an Outdoor Wood Furnace?


Tired of furnace and heating repair? Consider adding an outdoor wood furnace to your heating system. An outdoor wood furnace is a piece of heating equipment installed outside of your home that can be integrated with your current furnace, boiler or other heating unit to make your home more comfortable. It improves the quality of your home heating and allows it to be more consistent, affordable and environmentally friendly.

Outdoor wood furnaces require less repairs because there are less parts that can malfunction. They are also more efficient, able to heat multiple buildings and easy to service—plus most homeowners can utilizing their own land’s wood to heat their home. That makes it environmentally friendly, since using wood to heat your home is a renewable resource, which reduces your carbon footprint.

How does an Outdoor Wood Furnace Work

Think of an outdoor wood furnace as a wood stove that is located outside, and is housed inside an attractive storage shed. This minimizes the risk of a fire, while still providing quality comfort and warmth. An outdoor wood furnace is designed to work with any existing heating system. By using a traditional thermostat, you are able to maintain an even and steady temperature inside your home. After the wood is burned, smoke passes through the water jacket to convert the heat in the exhaust. A water jacket surrounds the furnace firebox and heat is transferred from the wood fire inside the shed to the water, which flows through insulated pipes to your home.

You can heat your home and your water, too. With a water-to-water heat exchanger, you can turn off your hot water heater and save money. An outdoor wood furnace is extremely adaptable, allowing you to heat multiple buildings at once. Whether it’s your garage, workshop or even your swimming pool or hot tub, you can heat all your interior spaces with an outdoor wood furnace from Central Boiler. You can even choose from a variety of colors to match the exterior of your Duluth home.
