Hello mates, I have finished my rocket mass heater. I want to thank this forum and its members for Their help and expertise. You can see the video how it's made​​. Best regards.

Hi Aurelio; Very nice build, I especially like your brick work. superb music also! thank you for sharing.

I've embedded the video below.

Nice work Aurelio !

Interesting use of barrels under the bench! I had not seen that before.

How long of a burn before it all heats up?

How long before it cools back down again?

Did you coat the cob with anything special?

Thanks guys, for your kind words and embed the video.
I have no data for your questions, It only just worked four hours, the bench only slightly heated by the collector area close, it is still wet. The coating is lime stucco, colored with clay.

Hi Aurelio: I have been watching your video again and again this morning.What are the dimensions ? Is this based on an 8" or 6" system ? The bench appears to be apx. 6' long , how wide, how tall ? Please keep us updated on your temps as this drys out. I am building my second rmh this summer in the shop, but your design looks like it could be the third build, in my house !

Conbgratulations Aurelio!

Waiting to read for your comments on how it works when it's fully dried!

Enhorabuena!

Esperamos comentarios de cómo rula el chisme cuando esté seco

Abrazos

Thomas, in fact, it is 8 inches. I did the system with half barrels for materials economy. The problem is that the barril has height of 29 cm and there aren't enough mass on the bow, this means one line too hot in the middle of the seat. The seat is too high for ergonomics (40/45cm). You can see the picture with measures. We must to put one long wood bench and the feet not hanging.

Very nice looking and simple design. How tall is your exterior vertical chimney stack?
It's a bit late, but you might have put a more insulating layer of ? right over the top/middle of the barrel chamber were the seat cob is the thinnest.

Well, everytime i see something like this, i think of one of thoses. Don't know how typical to France they are, or if there's some in the us or elsewhere. But turn one to the side and you have an instant bell seat

Hi Aurelio; Thanks for the measurements. I suspected that you might have a hot spot with the arch of the barrel. If you were able to use 8" pipe thru your bench instead of the 1/2 barrels the bench could be more ergonomically designed. I do like your brick work and basic idea of the half barrel is a very good idea in places where stove pipe is hard or expensive to get. You have me thinking now, that those barrels are really an interesting idea for my shop heater build this summer. (Mini Bells ) Seems like that much room would allow me to push hot air that much farther with the lack of restriction...? Please keep us updated on your build, it will be interesting to see your improvements. Good Luck Tom

John, actually, the seat is too high for to avoid too hot line, there are 15 cm of cob on top of the barrel. The chimney is 3 m high.

very nice!!! love it!

i too like the half barrel idea. the hot spot area is something i didn't think about. is the flow affected in any way that you noticed?

The stove is dry. I've done a little test of three hours working. 11 kilos of firewood, mixed hardwood and softwood were burned. ¿11 kg / 3 h it is correct? It was not enough to heat the whole work. The back remained cold, the seat is heated well in the start smoke route, perhaps too, perhaps with a longer burning becomes uncomfortable, what temperature is right? Moderately heated in half and only slightly into the end of travel of the smoke. After six hours the temperatures remained well off, touch sensation, and 24 hours later still feeling heat felt, especially in the area close to the manifold and body mud stove.
Sorry I can not provide more accurate and comprehensive data. I think even the cold season arrives we shall not use it. In the Mediterranea area the heat just came here I will update the data in the future
