Well Sean, your right I am trying to tweak it as far as it can go, further than any one has, I think. (and maybe too far but nothing ventured is nothing gained) Yes I know my old church is a pain to heat too. It goes back to budget on everything of which i have none. That's why I need every bit of heat I can get into the battery and room. Your insights are appreciated negative or not. This is all new to me and I had to fly blind, we are very low income, I have a sizer condition and haven't been able to work in three years outside of the home. So I had no money to buy any plans or videos or supplies. I have had to do this with the free information on my own researching what I could find and from teaching myself. So there are a tremendous amount of gaps in my knowledge. I'm trying to make up for with experimentation. Now Just for a need for clarification. The forced air system I built is threw the bench only, I have a slow draw of air from inside the room, the intake vents are pulling heat into the air in the air duct from the outside of the barrel, to circulate the air threw the heat battery ( in theory) heating up the clean air as it moves threw, then out into the room. That part of my design will only work once I can get the bench to heat up. I have not put any fans inline with my exhaust so it has no effect on draw. I can if I can get another one. All the draw I was getting was from my heat riser and that part was working. My area of expertise is in electronics so my home power system I have made so electricity to me is free. The thing is, the amount of waist in an electrical heating system and the wear on the system using heaters on it are tremendous so this was my alternative. (you can blow inverters like crazy and the overpowering required to protect them makes the ones that will work unaffordable for me.) I could put a fan inline with the exhaust, I suppose, on the side by the chimney pushing out but I want to see if I can get it to work with out one. In fact I thought it was. We will see. I finally got rid of this fever after two months now its below zero outside and by extrapolation in my home. I just don't get it, the planets warming up and in my little neck of the woods its colder this year than in a long time. I figure the goddess is testing my resolve..lol.. anyway thank you again, Sean all information I get is more than I have so it's good.

Well i will understand the damage better once I can get home and take the barrel part off and get at the heat riser to see how bad the damage was. I think it was just the burn chamber that burned up but I got sick right after and haven't been able to start on the rework investigation. I will take pictures and share my folly as well as what I do to fix it. Thank you all again for all the dialog and help. I'm basically on my own here so it's nice to talk with others that are doing this.

he is right..lol.. I was thinking of using the cob to encapsulate the burn chamber on the outside, I used the two pipe method originally with vermiculite as the insulator the inner one burned up. I need the circular construction to get the fire to burn with my design properly but I need to make it stronger. I was thinking about a double or triple walled inner pipe to replace the one I burned up. Any thoughts.

i still think you nailed my problem, The way i made it, I need to insulate the barrel. but time and experimentation will tell. I will let you know as soon as I can work on it again. Thank you for your time and the advise it is much appreciated.

No that was me its not in the book. by increasing the heat riser ratio, I increased the rate at which the hot air moves by increasing the distance at which the hot air moves up. Hot air rises at a constant rate, my hypothesis was to maximize the draw by giving the air more room to travel up and increasing it's speed. The further straight up (obviously its not absolute there is a point where its no longer effective but i think I maximized it.) the faster it exits. there by increasing the draw from the system. Allowing it to use all the fuel in the wood. that part worked. Almost too well. I got white ash out and the draw was strong enough to feel the suction and burn the fire hot enough to melt the 30g steal inner lining on my burn chamber. This was my first experiment and so I know I was going to make mistakes, I could not afford the book or most of this I have been working as best as I could with no budget and very little information I could not figure out for myself. Most of this is clay from my yard. So I had to do things unconventionally because of my budget. Unfortunately I live in IL where everything is expensive and no one has any thing for free. They even want me to pay for garbage. it seems. Any way if I completely screwed it all up it wouldn't be the first time but I will make it work I have to.

These are the last pictures I took before i had to break. I still have to level the bench and build up the cob on the barrel. I was going to leave the very top open as a cooking surface but i could build a cob stove over it to keep more heat in.

Yes, I was actually going to cover the barrel and the air draw completely with cob, I got stuck in the middle of finishing. But that helps, I think you got it. from looking at it. I didn't realize you could loose so much heat in the barrel. I have the air part of the system separate from exhaust part of the system however, the fans and electric are on the air duct work only. My heat riser ratio is longer than the plans stated to increase the draw, it was working before the meltdown and freeze and flue. I got white ash out so it was burning well for three days. Thanks I'm feeling better finally, I think. Anyway, communication is not my strong suit (I have a degree of autism) so maybe what I am doing is unclear. but the idea was a standard rocket mass heater with a stronger draw created by a higher heat riser and a separate system pulling heat from the cob into the room with blowers. I own an old church so its a large living area I'm trying to heat. Once I can fix my burn chamber (which I melted) I will be able to look at it again. If I need to completely change out my piping, well that's a mess I would rather avoid if I can.

I don't understand the question/comment. My power source for the blower part of the system is my home power source which is from my solar/wind and batteries on the blower part of the system. Now I did use a flex pipe for both the blower part of the system and the exhaust part of the system, the stoves I saw, some of them, used it and it was much cheaper so I went with that and considering my limited budget it fit better than trying to use the strait pipe. Are you saying it wont heat the bench?
My temperatures at the end are none existent so I figure it is going into the bench. Of course I'm still sick so i haven't been able to work on it in over a week. Please clarify. Thank you.

btw, I had to look up the HRV so its not exactly what I've got going one but its close in principle I think.
