 The stove is finished & awaits clay plastering during the nearest spring. It is fired daily but not with dry wood :-( The house is insulated but not air tight as it has some old entry doors installed. Some more photos of the construction phase can be viewed in this album. Some issued of this built are disputed here

Ooww, that's a biggie! And single skin as well, I am very curious whether or not it will develop cracks during this season.

I counted the ISA and in fact it is a bit too ... small for the 20 cm beast. Any specific place of where would one could suspect the cracks to develop? The skin is from a chamotte brick used in a metal smelting kilns. It has a huge heat capacity. The joints are 2mm maximum. So far the phenomenon of firebox brick moving hasn't occurred. |

Jura you mention this is in the Polish coal basin, have you ever burned coal in any of your batch boxes or a j tube?

Jura you mention this is in the Polish coal basin, have you ever burned coal in any of your batch boxes or a j tube? No. I have not. In fact as a chemist with specialisation in coal and fuels I'm against burning coal by individuals as it is too precious and not renewable substrate. |

Yeah that is understandable and I agree with you. I’m in mongolia where most people burn coal and I’m curious if we can at least help the air for all the homes that burn coal, then as wood becomes more available and if rocket mass heaters or a similar thing becomes familiar people can burn wood and still save money.
Thanks for your reply

Yeah that is understandable and I agree with you. Thanks for understanding. I also know what it means to live in a contaminated area.` As U may suspect the coal here used to be relatively cheap and many ppl got used to it. Now due to energy poverty those ppl burn any trash possible which make the air contamination reach Beijing level :-( IMHO The only way to make sensible use of coal and avoid pollution is to convert the coal into so called syngas by high temp steam gasification and burn thus achieved mixture (still to precious to burn) while directing the flue gases to a purification installation. Which is not feasible with home condition. Are you based in ex-Urga? |

Yeah definitely not feasible for homes.
I don’t think so, I have never heard of ex-Urga. I’m near the Russian border on the Mongolian side near altanbulag and Irkutsk

I’m near the Russian border on the Mongolian side near altanbulag and Irkutsk I'm wondering if for you being so close to the RUS the wood is easily available. As in Mongolia it is rather scarce article. By Ex-Urga I meant the former name of Ulan Bataar  |

Oh haha so we are about 300 km from UB. Yes we are close to Russia but wood is usually sent through here to China or other things. It’s available but not as much as coal.
Back on topic, your stove looks great. How is it running?

hmm....How is the stove operating.. that's a hard question ..really.
It burns the wood in a rocket manner, it gives a lot of heat but as the building stood 2 years cold and is not yet airtight the owner is not able to maintain 20 centigrades tempinside with one fire a day.
I hope it burne and extracts the heat efficiently but to be sure of it I'm trying to arrange a visit of sb. with a Testo.

I understand. By one fire a day do you mean just one load of wood or a single burn that may take two or three loads? Did you lay all the brick yourself? I am searching for tips from any experienced people.

1 load is ~11 kg of soft pine wood.
Burnt in one process.
It takes ~75 min to reach a minimal amount of glowing wood remains at which point the owner closes the air inlets.
Yes, all of the stove has been build by my hands.
And it's a fourth stove my palms erected.
There is link to the photo album.
Maybe it may be of any help for you.
Btw -21 in Altanbulag.. brrrr.. that's pretty cold.. I just hope there is no wind and high humidity.
