everything is 8" all the way through the roof I took the spark arrester off last night and did see some improvement but not enough to say that was causing the problem. I took pictures of all the pipes in the bench and everything looks good no rags everything is round. The bench is dry it has been a month or so drying I am putting off the final coat till I get this thing running correctly. David

The gap at the top where barrel and heat riser is 3" the heat riser was finished flat on top ? The bench has 4 elbows 1 45 with about 12'+ of 8" piping which makes it look like a big P going to the chimney which goes up through the roof and 2' above that with a wood stove spark arrester cap {it is clean}. the burn channel is 10" long the heat riser is 44" top to the bottom of burn channel the cob around the piping is dry. A mixture of cob,river rocks and 1/2 to 3/4 crushed granite. David

It is winter now in the high deserts of Az my RMH bench is dry, I get a rocket noise when the wood is in just the right way and it does draft, but the temperatures are very low (magnet temperature gauge) it barley gets to 300 deg. 90% of the time it stays at 250F or lower or about 100C this is on the side of barrel at the very top. Could my ash pit be too big and causing a problem with the burn? I have attached 2 pictures (I hope) that show the ash pit section any comment would be very helpful. TIA

Just in case pictures do not turn out.

Ash pit measurements 12+H at the barrel 24" across at barrel tapers down to 8" pipe about 22" long.

How much insulation do I need to put around the feed tube and the burn tunnel. Or do I need to insulate it at all? TIA

My Question is what will work better for sealing the gases in the clean out caps that go on the out side or the ones that go inside like a cork?


Thanks

I used a 40gal WH tank to cover and insulate the heat riser (16"W)with a 55 gal drum 22.25"W with a 3" gap(c) on top that leaves little over 3" gap(g) along the sides is this going to be a problem ? TIA Azdave

My RMH is made of 2.5x4.5x9 fire bricks with a old WH tank around the heat riser inside of 55 gal drum which gives me a 2.5" clearance all the way around the riser. My question is how long do you all think the brick will last before I have to replace the burn tunnel and the heat riser our winters are not that bad not like back east but it does get cold at night in the high desert. Just getting the WH cover off of the heat riser is impossible without destroying the heat riser. TIA Azdave
