I am looking to sell my working RMH to a local Wisconsinite ! Richland Center area email if interested msgbfg89@yahoo.com thanks

I am no expert ,but I have three thoughts on this looking at your pictures.First you might try taking 2 sections of pipe off near the 180 degree turn.This could improve your draw by shortening the overall length .Also as a general rule the chimney should be 2 feet above anything within 10 feet.If its still possible to shorten your burn tunnel that could help too.

Ok,well to wrap this up,last night I made tabs and bent them over to the barrel (picture 3) and then I crudely insulated the feed tube/burn tunnel area with face brick.I also covered the holes in the base layer of brick that the system sits on.The draw improved slightly but the temperature increase was really good (400 +) with an oven therm.surrounded by brick.This is also with less than seasoned Hickory and Maple.So thanks everyone for the help! I believe that with better insulation around the core area and dryer wood,it will be even better yet.As far as my dimensions and barrel placement are concerned,I think the system will run well as is.This is a work in progress you could say ,and its looking like WE have the bugs mostly worked out now.Thanks again!!!

Byron,I have 5" at the riser to barrel and then 3" as it goes around to the other 2 sides.The 4 th side is tight to riser.

Mikael,The entire J tube sits on face brick on edge so that the holes show and allow for heat transfer away from the concrete floor.I was afraid it would spall the concrete if moisture was high.

At this point I'm not worried about the Rockwool as I can change that if needed.I have ran this for many hours continuous without any loss in draft due to equalization.

The pictures are from today and don't show any signs except fly ash.Do you think that the CSA of the riser is slowing down the flow of the system?

Byron,i can probably get in and make tabs and get them bent and clear.The riser is wrapped in fire rated insulation with the fire brick being on edge.Then wrapped in galv.sheet metal.The bench area is at this point only covered in busted up concrete block in sizes from sand to golf ball.Everything is deep freeze here and waiting on warmer weather to complete the mass in a less insulating fashion.

The burn tunnel area is covered with brick but that is the only insulation there.
