   Hi everyone! I started building a 21 cm batchrcket, but due to the specific position of the chimney and my intention to heat 3 rooms with the bell the following problem emerged. About 35 cm from the riser lies a wooden support pillar, which needs to be protected from the fire in the best possible way. My plan at the moment is included in the attachment. Any opinions and advice on the matter would be much appreciated. Thanks in advance! In this case I suppose I will have to exclude the space in front of the fireplace and the support pillar from the ISA. thanks |

Can you shift the main bell to the left so the chimney is on the rear right corner to maximize clearance? 15cm is the recommended distance in US building code for masonry heaters with 2 layers and seems like a good minimum. Insulating the inside will help. I have had good success with shiny sheet metal heat shielding on wood near stoves. Always use some type of standoff to give 2.5cm clearance between shield and wood. Having the air movement behind the shielding is in my opinion better than insulating against the wood.

Thanks for the advice! I have thought about moving the main it to the left, but this way the fire chamber will be placed next to the right wall of the bell, thus severely compromising the warm air flow towards the bench and the part of the bell next to the right room

I don't really finish to understand your question, but if you isolate from inside the bell, you have to exclude that area from the ISA calculations. I guess like joseph said superwool on the inside and plenty of air moving from the outside will do the trick. |

You understand the question exactly,
Thank you.

It looks great. How are the temps by the pole? I guess it's not the time of year to give it a full burn
