So you want to build an OWB you say...

[H-Ranch]

Resurrecting my brief OWB build documentary that was lost with the "old" site.
Started with a couple of propane tanks - a 250 gallon vertical and a 500 gallon. Inner tank is 32" diameter and outer tank is 42" diameter.

 

[H-Ranch]

Cut the opening for the door in the bottom of the smaller tank. Then welded the end plate to the tank.

 

[H-Ranch]

Put the two tanks together. Had to crawl inside to weld the stack to the inner tank.

 

[H-Ranch]

Welded up the door with insulation inside. Decided not to plumb with water to reduce complexity and potential for leaks.

Simple hinge with slotted adjustment and tapered latch.

 

[H-Ranch]

Welded internal baffle to keep heat in longer and minimize sparks coming out of stack. Mounted the assembly on legs. Made tall enough so I don't have to bend over to look inside to put wood on top of fire.

 

[H-Ranch]

Insulated the outside then built a steel shed to go around it.

 

[H-Ranch]

Trenched for PEX about 100' from the house. Pump mounted directly to living room floor joist and I can't hear it with my ear to the floor above it. Heat exchanger in propane furnace with PEX lines through foundation to allow for expansion when hot.

Looks good. That decking should make some pretty solid siding for it as well.

That b-decking isn't cheap but looks really nice.

Looks great, glad you took the time to update and reload.
I have a couple of questions for you, where did you find the tanks and do mice get into the insulation?
thanks,
dave

/me looks around sheepishly...hope no one notices..

I don't get it, where is the hot water coming from? You said, decided to not plumb for water, leaks, etc, then there is a pex line and..huh, what?

zogger, he meant for the door. He didn't bother to run water thru the door. The tank still has water just not the door.

Nice job! Looks like you did it all on the cheap! I'd like to do a similar unit .My current Shaver 250 has been ok but it's too small for my home,I'd like to build one with a 42" inner tank,at least 6 ft long,with a 24x 30 door...tired of not being able to load big rounds thru my 18" door...

Me too, you go first and post pics and stuff....

I've built three forced air wood burning furnaces....I think I can handle it. I just ain't got time.

I think a forced air heater is more along the lines of what I want to do. I got an ideer in my head, just no time to do it.
