Because common pipe is in whole inches, what consideration should be given to interior diameter through the tubes?

No no no and no!   https://permies.com/t/52544/metal-burn-tunnel-heat-riser

Bryan,  my design doesn't require much welding, if at all.

You van skip metal containers if you wish. Replacing these with double skin bells. There is tons of solutions.

I would say, go for batch. Forget thé jays.

Mass is approx 2000 kg in bricks alone. Add to that cob/clay/stone filling.

Well, explain then.

One barrel above the riser, i count 1.86m².

By the looks of your drawing, i wee two half barrels, so that's a bit less than 1.86, since the plunger tube doesn't go down to the floor. Only the active part is taken into account, not floors.

The convective heat is good imho, and the conductive heat in the wall is good too. Nowhere near perfect. The worse bit, is all the dust that hot air brings upstairs. It's a workshop below.

First thing which comes to mind, not enough isa or heat extraction surface. Not enough mass for a 200mm.

Well this thing heats up my workshop, and my flat above. I haven't gone under 18C° when it was -17C° outside. Typically around 19C°/22C°. in the flat. Going from 15 to 20C° in the workshop.


113m² of workshop 57m² of flat approximately. And around 635 m3. Euro R7 in the walls, but not on all of them. South and east facing entrance walls are not insulated more than R1, flat gables are R2 or 3 big maximum, and R3 in the roof. All of this is euro R values.

And i usually burn this much oak in three burns a day. One morning, 2 evenings. One more in the evening if it's bellow -10C°.

Bruce, i'll put it bluntly.

Your thing is not a rocket. A fumivore if you want, but not a rocket. And it's getting on the nerves of several people here, that you're pushing your core on every occasion.

What would be good, is that you would report after two or three burning seasons. So we can see what your results are. Another good thing to do, would be to have someone with a testo, test it.

On another side. You don't need to push it so hard, you have nothing to gain. You have not reinvented the wheel. People have done it this way before you. And nobody will hire you to build one.

I wish you all the best.  But try to learn more here and on other websites, and give more convenient solutions than your metal thingamabob.

Well, good luck.
