In short: to date, the design of the batchrocket combustion unit has proven to be fully scalable. One could wonder what the upper limit would be, assuming there is any.

Thanks I will take another look at the batchrocket site  to see if I can find a mass heater example that would fit. We have about 170m2 to heat on two levels and we rarely get below 0 degree Celsius outside but the temperature in the farther away rooms has to stay above 14 degree Celsius 😁
Reading about people melting the interior of their rocket stoves or having cracking issues in the fire chamber seems to indicate you really have to find a good plan with mass heating option or know what you are doing.

Thank you. So it is about claimed efficency and not about faulty planning as far as clogging up or creating other dangerous effects, in comparison to an open fire or standard stoves.
The problem I see with rocket heaters for my purpose is that they are said to be for smaller stoves in comparison to the Kuznetsov types and I want to heat a larger farm house with only one stove. To replace the cast iron stove that is filled every few hours....

Thank you. Good to hear, if anyone has links to discussions of problems with the Kuznetsov design please share. I guess there is as in everything different "schools"...

Hello, I wanted to build a Kuznetsov stove this year and now read a few negative comments about the dry seam. It seems though that in Russia quite a few of these sometimes huge stoves have been built . You indicate that it will not work properly or you just have not seen test figures?
Thank you.
