How Does an Outdoor Wood Burning Furnace Work?

An outdoor wood burning furnace is an efficient and cost-effective way to heat your home. By burning wood instead of fossil fuels, you can save money on your monthly energy bills. If you're considering installing an outdoor wood burning furnace, it's important to understand how these systems work. Here's a quick overview of what you need to know.

The Basics: Combustion & Heat Transfer

Wood burning furnaces utilize the principle of combustion to generate heat. When wood is burned, it releases heat energy that is transferred to a heat exchanger. A fan then blows this heated air into your home through ducts. The heat exchanger acts as a barrier between the hot gases produced by combustion and the air that is circulated into your home.

Stages of Operation: Startup, Burn, & Shutdown

An outdoor wood burning furnace typically operates in three stages: startup, burn, and shutdown. During the startup stage, the fan is activated, and wood is loaded into the combustion chamber. The thermostat controls the fan's operation to maintain the desired temperature in your home.

Once the fire is established, the furnace enters the burn stage. Wood continues to burn, releasing heat into the heat exchanger. The fan circulates this heated air throughout your home.

When the desired temperature is reached, the furnace enters the shutdown stage. The fan continues to operate for a period of time to cool down the system. Once cooled, the furnace will shut down and the fire will go out.

Fuel & Efficiency: Choosing the Right Wood

The type of wood you burn in your outdoor wood burning furnace can impact its efficiency and longevity. Seasoned firewood is the best choice for burning, as it has a lower moisture content and burns hotter. Hardwoods like oak, hickory, and maple are ideal because they burn longer and produce more heat than softer woods like pine.

Maintenance & Safety: Maintaining Your Furnace

Proper maintenance is essential to ensure the safe and efficient operation of your outdoor wood burning furnace. Regular cleaning of the heat exchanger and chimney is necessary to prevent the buildup of creosote and other potentially dangerous materials. Additionally, it's important to inspect the system regularly for any signs of damage or malfunction.

Environmental Impact: Clean Burning for a Greener Home

Outdoor wood burning furnaces can impact the environment, especially if not operated properly. Incomplete combustion can lead to the emission of harmful pollutants, such as particulate matter and carbon monoxide. By ensuring that your furnace is burning efficiently and using seasoned wood, you can minimize its environmental impact and enjoy the benefits of a warm and cozy home.
