An outdoor furnace is an efficient way to heat your home. Firewood is a cost-effective alternative to natural gas or oil, and it’s a renewable resource. Outdoor furnaces are designed to be placed outside the house, which supplements your existing source of heat and lowers your heating costs.

Follow these steps to learn how to install an outdoor furnace:

1. Create a concrete pad that is large enough to hold the furnace and provides enough room for you to stand when loading the furnace. Ensure that the pad is at least 4 inches (10.16 centimeters) deep. You’ll need to create a mold to pour the concrete into.
2. With a backhoe, dig a trench below the frost line from the furnace to the house. The trench will prevent heat loss or freezing of the pipe, since the ground will be between 45 and 55 degrees Fahrenheit (7 and 13 degrees Celsius).
3. Position the furnace on the concrete pad.
4. Measure the distance between the house and the furnace. Take a PEX pipe (i.e. hot water pipe) of that length and place it in the trench. Put a 12/3 110V wire of the same length in a 4×6 PVC pipe and place it in the trench too.
5. Put a heat exchanger in the outlet plenum (ventilator) of the furnace. You should be able to buy one that fits your plenum. The heat exchanger should easily slide into the plenum, and you can fasten it in place with an L-shaped bracket.
6. Connect one end of the PEX pipe to the furnace and the other end to the heat exchanger in the hot water heater. Use another pipe and a pump to attach the remaining end of the PEX pipe to the hot water heater.
7. Install the circuit breaker into the breaker box. Attach the 110V wire to the circuit breaker and the furnace. Install and connect the thermostat.
8. Fill the furnace with water. Start the fire. [source: Outdoor Wood Furnaces]
