These free DIY wood stove instructions include various approaches. Use economical wood for heat without the sky high initial investment.
There are a great many applications for DIY wood stoves. They can go right inside your home, out in your barn, or in a special building for your home built wood burning furnace. Whatever the application the layout will remain the same. A combustion chamber where the actual fire is burning, a stove pipe for venting the smoke, and an air intake control system for regulating the amount of air entering the combustion chamber.
DIY Wood Stove for the Barn
A do it yourself wood stove for the barn can be a little more lenient on tolerances than one built the house. Their a great number of kits that work quite well for such applications including those that convert a spent 55 gallon oil drum into a very efficient heater. There is but one problem with this approach; it is not very durable. A drum will last only for a season or two. The only good thing about this is that the kit is reusable; just replace the drum. It is best to replace all stove pipes at this point as well.
DIY Wood Stove for the House
The do it yourself wood stove for the house presents a little more of a challenge. Tolerances need to be at their minimum. Smoke inside of your home is something you can do without. There is also the risk of the fire spreading from the heater to your because of a catastrophic failure. If you are not completely confident with your metal working skills and DIY skills, then DO NOT try it!
The ideal heater would be built from 1/4″ plate steel. it would have a reliable door and have fire bricks on the bottom on the bottom and sides of the combustion chamber. The air intake would be a simple adjustable slot in the back. The air intake needs to feed fresh air to the bottom of the combustion chamber. Remember this fact when designing your DIY wood stove.
DIY Wood Burning Furnace
These unit leave a lot of margin for creativity. They work better when they have their own enclosed building to help keep their heat from escaping into the atmosphere. There are many commercially available heat exchangers you could design your outside wood burning furnace around. There are also simple methods to build your own. One very efficient method is to coil water filled copper tubing around and around itself and place it near the top of the combustion chamber. A high temperature pump circulates the fluid to your house where it can be released by exposing more coils to a moving current of air. The design possibilities are limitless with this approach.
Whichever approach you decide on, just remember you are dealing with fire. Always respect fire; it can hurt you and others in the blink of eye. Good luck with your DIY wood stove!
