Building an outdoor wood burning furnace

The entire process of building an outdoor wood burning furnace. This furnace is now heating a 5,000 sq. ft. house and it's domestic hot water. This is the way to get off of using oil to heat your house. After 3 months of construction and roughly $3,000 in materials and scrap that was laying around, we are now heating the house for free. A Do it yourself (DIY) project.

ah, this is not a 'furnace'..but a boiler...what are you heating air or water..?? Where is the refractory lining to keep the creosote from condensing on the cold metal...??? Learn to do it right....!

@novokarpati

No need for a lining. creosote burns away from inside burn chamber. once a season, shut the unit down and scrape what ever is on the inside. it's actually very effecient.

how do you keep it from rusting out in the water chamber?

[gwana8919]

@chasehav2014 add rust inhibiter to water

[1kenziesmom]

do you have to have a basement to use this set up

[gwana8919]

@1kenziesmom Basement is not needed. all you need is oil, gas or forced hot air system, and you can fit one of these to work. Doesn't work with electric baseboard heat.

Do you lose much heat to the ground? Only reason I ask is that the pipes don't look very deeply buried or wrapped with much insulation! Also is there much heat transfer between the pipes in the big"o" or does it matter much? Thanks.

Speechless!!!

[davidlathamjr]

Great video, music, welding and humor. Very profesional job with all crafts. Thanks !!

[gwana8919]

@robertsulley Actually, one heat exchanger would be enough. we added 2 for more effeciency

[redneckrollercoast1]

don't use a cast iron pump it won't last in an open air system like that!
