Outdoor Furnace: Benefits and Drawbacks

Outdoor furnaces are becoming a popular heating choice with increased fuel, electric and natural resource costs. Many people want to heat their homes more affordably and are now learning more about outdoor furnaces. Before you decide to purchase one, it’s important to know the pros and cons of having such a system.

What is an Outdoor Furnace?

Outdoor furnaces are radiant heat systems. These systems heat wood or wood pellets that ultimately heat water and coils. The water is then circulated through your home using coils or pipes.


These systems are costly to install. An average outdoor furnace costs approximately 6 to 7 thousand dollars, and this is the largest drawback for many.

Owners of outdoor furnaces will have to go outside to maintain these systems. Unlike familiar heating systems where users turn a knob or push a button to stay warm, outdoor furnaces require users to go outside and put wood or wood pellets into the stove. This can be particularly inconvenient if you have to leave the house in the middle of the night in inclement weather conditions.

There are ways to combat this problem. It's important to consider what you will use as fuel for your outdoor furnace. Owners can use wood, wood pellets or a combination of both. Wood pellets are more expensive than wood but last much longer. Wood pellets are known to be able to heat up to twenty-four hours.

Wood is much more affordable but rarely lasts more than 4 to 6 hours at a time. Depending on which heat source is used, you may have to maintain your system many times in a twenty-four hour period.


Outdoor furnaces are energy efficient. If you are trying to cut your heating costs, they're much less expensive than other heating systems once they have been installed.

Wood is also one of the most economical burning agents. With a little resourcefulness, wood can also be a free source of heat, although users can just as easily buy wood.

An outdoor furnace has a higher eco-friendly aspect to it. Wood stocks are now being replenished at faster rates than ever before, with new trees being planted for every one that is felled in many areas. Natural gas, a diminishing resource, also leaves a larger carbon footprint than burning wood.

Outdoor furnaces are also clean to operate, compared to other internal heating options. Users do not have to bring wood into the home or deal with the dust that stoves create. An outdoor furnace will contain any mess to the outside of your home.

These systems are safer than traditional wood-burning stoves. If the furnace catches fire, it will do so outside of the home and directly away from property.
