Don't forget the V-shaped floor takes up a 5th / 20% of the firebox. You can make the firebox smaller if you think it's going to be too much heat for the space. I reduced the width of mine a bit this year as it was over heating my house, have it at 265mm wide now, I just used 2 pieces of vermiculite board to bring the sides in 20mm each.
Are you planning to use all that mass around the firebox un-insulated? If so you could have the same issues Pat had. The fire will start off OK as it's lit from on top and the fire is insulated from all the cool mass by the firewood until it burns down, then towards the end it can bog down and smolder with half burnt logs buried under coals. What thickness are the firebricks? I recommend 45-50mm / 1 3/4"-2" firebox walls on a 150mm / 6" stove. If I was building mine now I'd do the firebox 45mm / 1-3/4", maybe even a little less.

We have only 65 mm thick firebricks on market. If I will use secondary air heaters (double walls), so inner fireplates are 25 mm thick. Back fireplace wall will be insulated, becouse it close to rear wall. I want to use heat frome firebricks to heat up outer red brick shell. In bell stoves lower part of stove not heated at all, if fireplace insulated.  [/URL] |

1 CSA ideally, minimum 0.75.
160 mm system size, 1 CSA = 20109 mm2, 0.75 CSA = 15082 mm2.

Bypass placed 30% of the bell height from the ground. Семён Семёныч... Байпас лучше расположить несколько выше вторичной камеры , чтобы обеспечить прямую тягу . It is better to position the bypass slightly higher than the secondary chamber in order to provide a direct cravings. |

It is better to position the bypass slightly higher than the secondary chamber in order to provide a direct cravings. I am absolutely confident that my worker will forget to close the bypass. I need insurance against forgetfulness. With this bypass ISA will be less by 2 square meters, so everything is fine. It's better than just a straight chimney all the way to the bottom. |

Олег , ты забыл о байпасе , у тебя могут быть большие проблемы , особенно при первой растопке . Пока не поздно исправь это . И да , вторичную камеру я бы сделал повыше на треть . Oleg, you forgot about the bypass, you may have big problems, especially during the first kindling. Before it's too late, fix it. And yes, I would make the secondary camera a third higher. I would not. Afterburner height is enough. My stove - my responsibility. If to isolate stove, ISA is 6,1 square meters. With bypass open it is only 4,2 square meters. Clear ISA of my first stove is 5,5 meters (stove and top of stove are isolated), no bypass. Stove starts OK even with zero outside, even with chimney height shortened to 5 meters. |

My stove - my responsibility. Ok. Your mistakes will be your problems. Show your stove, if you build stove like that and we will discuss it. I've followed your advices before, twice, and both had problems. Thank you for advices, but they do not work. I've got my head on showlders. Шур, отвали. Я два раза следовал твоим советам и оба раза были проблемы. Сам разберусь. |
