What is an Outdoor Furnace?
Wood and Coal Furnaces are located outside at a desired distance from the building being heated. The unit consists of a firebox inside an insulated water jacket. The entire unit is covered by a protective metal exterior.
Legend Outdoor Wood Furnaces offers high-quality furnaces designed for both wood and coal. With identical dimensions, each model is tailored specifically for either wood or coal, ensuring optimal performance and efficiency for your heating needs.
The heat from the firebox is transferred into the surrounding water jacket through an internal double-pass flue system. An aquastat controls the combustion in the firebox, keeping the water temperature in a desired range. The heated water is then pumped through insulated pipes from the unit to the building being heated. An outdoor furnace can be used in conjunction with or in place of most existing heating systems.
Why Use an Outdoor Furnace?
Outdoor furnaces can provide heat evenly throughout the home using existing forced air or hot water systems, keeping all rooms at the same temperature, unlike typical indoor heat systems, which heat the immediate space that they occupy and are not able to disperse heat to other areas of the home. With outdoor wood furnaces, any of the mess and fire hazards associated with wood or wood burning stay out of the home. Dirt, sawdust, ash, bugs, and other debris are left outside and not carried into the home.
Using an outdoor wood and coal furnaces also reduces dependence on fossil fuels, which in turn helps conserve energy. Wood is a totally renewable resource, is readily available, and is one of the least expensive heating fuels available.
Evenly Distributed Heat
Outdoor wood and coal furnaces can provide heat evenly throughout the home using existing forced air or hot water systems, keeping all rooms at the same temperature, unlike typical indoor heat systems, which heat the immediate space that they occupy and are not able to disperse heat to other areas of the home.
At Legend Outdoor Wood Furnaces, we specialize in providing top-notch furnaces suitable for both wood and coal. Each furnace shares the same dimensions, with one model designed for wood and the other for coal, ensuring you get the best heating solution tailored to your fuel preference.
Thermostatic Controls For Ease of Use
Outdoor wood and coal furnaces are thermostatically controlled to provide a comfortable and steady indoor temperature. Thermostatic controls, along with the large firebox size, allow for long burn cycles. Most owners only need to fill their furnaces every 12 to 24 hours, depending on the conditions. A large firebox also allows for larger wood pieces and eliminates having to split logs.
Additionally, our furnaces feature convenient front controls, including a 3" diameter thermometer, light and fan control switch, and a light fixture. The rear section offers easy access for plumbing with four sets of heat zones (one solar adaptable), two domestic water outlets, an enclosed electrical connection, and a large door for easy cleaning.

Environmentally Conscious Heating Solutions
Wood is a totally renewable resource that, when burned, results in no net carbon dioxide increase. Carbon dioxide is part of the natural plant-growth cycle and occurs naturally when plants rot. On the other hand, fossil fuels, when burned, release carbon dioxide. This causes a net increase in carbon dioxide, which is believed to be responsible for the “greenhouse effect.”.
Keep Your Home Clean and Safe With Us
With outdoor wood and coal furnaces, any of the mess and fire hazards associated with wood or wood burning stay out of the home. Dirt, sawdust, ash, and other mess need not be carried into and out of the home.

Home Heating That Doesn't Break The Bank
Using wood heat reduces dependence on the fluctuating prices of traditional heating fuels. Wood is one of the least expensive heating fuels available. Many outdoor wood furnace owners have ample supplies of wood available on nearby forestland and harvest their own firewood. Many logging services, wood products manufacturers, and other companies have waste wood available at little or no cost to you.
Versatile Heating For Homes, Businesses, and More
Outdoor wood and coal furnaces also have many additional uses. One of these is the ability to heat domestic water. Owners enjoy having an unlimited supply of hot water, not to mention cost savings on their utility bills.
In addition to heating homes and businesses, outdoor wood furnaces can heat many other applications, including shops, garages, barns, drying kilns, greenhouses, swimming pools, and hot tubs.
