Thanks for the input.

The build-up of soot and scale is an issue.

This design DOES work.
Ive used it many times.

For the scale I'll need to seriously think about that one as it's bore water.

The pipes that carry the flame I used to clean with a metal pipe cleaner thing.

But down the road it may have had issues with the soott and creasote at the flue end.
So I'm thinking that an access panel would be needed.

As for the clean burn issue.
The exhaust gases were very clean.
Whoever built it got the dimensions correct.

It would use about a bucket of small sticks to fill a bath with hot water.

I'm starting to wonder if it's the only one in existence as I can't find any pics or info on the net. Yet.

Thanks

this is sorta what im looking for,
excuse me for the rough pics

Thanks mart.
This design has no build up of pressure as it works similar to low pressure slow combustion stoves. A 1/2 inch pipe goes up in the air as the pressure release.

The keg basically has about 10-15 pipes running through it. The fore passes through the pipes.
Around the pipes is water.
So no pressure build up.

I have a rough idea of the design .
I'm just trying to find some plans to save me doing it twice. Or ten times. Lol
Thanks

Thanks Gerry and Thomas.
The design I'm interested in has the fire going though the pipes.
So it's the pipes that get exposed to the fire.
Basically the fire passes through the water.  Not water pipes in the flame.

hi
im looking for some plans for a hot water heater i had in a rental house once please

it was a beer keg on its side with many pipes going through it( like a steam train)
at the front was a steel  burning section, it was  triangular being wider at the top and the point at the bottom,
all of this was housed in a large cob
