Fella at work is talking about this all day and I said I'd post for
him. Now I'm wanting to find out also. He wants to build an outside
furnace with some sort of water jacket. He's been looking at some
plans on ebay he says has a 260 gal water jacket and take 14 pallets
at a time.
He's a welder and we have lots of almost free steel sheets. I've
heard of something similar which was covered with sand that is
supposed to hold the heat for several days if your away.
I've got some plans from a Richard Hill off the internet tonight but
haven't had time to look at it yet.

Isn't this the HAHSA design? Somebody? They're supposed to be great if
you need lots of heat and have lots of wood.....

He talking hot water or steam ......
Radiant heat floors or radiators.....or an Aframe coil in the central heat
and A/C.
He lagging or using just a water foot with firebrick or masonary.
He firetube like a steamboat or traction engine (multi tube),Cornish(single
firetube) like a gas water heater,or watertube with a water preheat jacket.
I run monotube or La Monte sort of a double monotube to a pressure vessel
that acts as steam separator.(evaporater and normalizer circuits) with an
added superheat coming off the pressure vessel and making a third pass just
over the firebox on it way to the engine.
Can think of probably a dozen other questions before you answer really
......
Sort of like the guy that asked about knob and tube wiring in a different
thread......need a few details of what he's got to
know what he needs to work on.
Sounds like he's got a good start from what little you can see in the
description.
No matter what he does he needs to insulate every single heat "leak" point
in his wood funace.
Some of the old boys with basement heat found that when they removed the
asbestos off the pipes for thier radiaters supply pipe/ boiler.
Found that bare pipe used 10 times as much fuel to heat the house.
And where putting ceramic or fiberglass insulation on in short order.

Some more websites to look at on how you want to use the wood or others ways
to burn the wood......
Gets tar,cresote,and smoke out of the way on the way to a cleaner burn.
And can be included in your furnace as well.....actually have factory guys
already building them.
Included one address at the bottom...many more out there.
And a guy with a MIG can easily build them all.....

I built a central wood burning furnace back in the mid-70s. It was inside the
house
(didn't like the idea of tromping through the snow to fuel it) but in all other
respects, it is like modern day ones.
I have recently helped two different friends install outdoor furnaces. Two
different
brands and two different designs but both work about the same. Well!
I can't imagine paying for plans. Such a furnace design isn't exactly rocket
science.
