a new design ? what are you building this time? Since i don't have much money nor time for the concrete bell, to house the batch rocket, this will do. I will try to fit the core in it soon. But have a roof to finish for a customer, before snow comes, you know that white stuff which fall from the sky ;D And 3 veluxes to replace for another one. So i'm working on this in my spare time. |

I am new here. And i am interesting why everybody is making such small feed tubes. Is it allowed to make them bigger? For example if i want that it will look like a simple fireplace. And i want to use such doors firemarket.eu/200-thickbox/zidinio-dureles.jpg  What i will need to change in all system? And i always was interesting why in normal (book) rocket mass heater feed tube is from top? An Peter i saw your video where you was using to drums, how tall heat riser was inside? p.s. Sorry for my english |

An Peter i saw your video where you was using to drums, how tall heat riser was inside? Insulated heat riser inside the lower oil barrel about 50 cm. long. Everything you've asked has been done before and it wouldn't work. Try for yourself, maybe you'll find something that will work, and we're pleased to hear about that. |

Peter what do think of that one with a rhombus "port" The video doesn't show how it worked. The title is telling what it is; a prototype, and beautifully built. But the results are missing, no second video either. Why don't you try to build this, maybe you can show us some ingenious stove and how it's done, instead of asking questions all the time. ;D |

Peter, I have been eagerly following your thread and I've had an idea to build a stove that would be a bell heater mass heater combination. I envision a horizontal burn tube with the riser inside a bell made with a steel tank covered with cob for the mass and have it exit into a tube that would run through something similar to the benches that so many talk about. This bench instead would resemble a kind of hearth with the bell made to look like a fireplace with a stone veneer over the cob. My question is will there be enough draw to pull the gases down into the mass under the feed box, fire tube and riser ( the hearth )?

Sorry what I meant was a horizontal feed and the gasses would exit the bell into the base which will be chimney pipe and thermal mass made to simulate a kind of hearth which the feed burn tube, riser and bell would set on top of. I hope this is clear. By the way you can call me Vern, The Virtual Maineiac is a nick name being from central Maine, USA. Also it's not uncommon to see -40 F here in late Dec. and Jan. so recommendations as to tube and other sizes will be appreciated. It might also help to know I live in an older 12' x 60' house trailer with a convention slow burner wood stove that uses about 6 cord of wood each heating season.
Thank You for sharing such great work It's very impressive.

Peter, we haven't heard about you in à while, whatcha'r upto? Some rockety stovety missbehavin? ;D Hi Max, Nothing new or special. Most of my time (of which I do own a lot, time is money so I am filthy rich) is going into wood hauling and processing. My fuel stock has been severely depleted by this silly rocket stove experiments and my Testo analyzer broke down again, big time. Repairs will be very costly but there's no alternative. More experimentation has to wait until spring I'm afraid. |

Hi Vern,
Welcome to the boards.
Since you are living in a house trailer you can't have much mass. A barrel with a lot of cob on it do need plastered almost weekly, because of cracking. It's better to have the barrel built as a masonry bell when you want even heat distribution throughout the day.
That aside, this horizontal batch box thingy is very powerful when built the right way. That's to say, with lots of room above and around the riser. When you want to make channels it won't be that successful, believe me. It's quite capable of pushing the gases down, even lower than the firebox itself. It doesn't like restrictions, actually the thing is a very good companion to a bell stove system.
Is this enough to think about for a start?

Peter,
Thanks for the response. My reasoning is motivated by my wife, she's not keen on the idea of a barrel in her living room and the masonry components are a bit out of reach financially, so we compromised on a progressive build beginning with the barrel and then decorating it later with cob and a veneer of stone and make it look similar to a fireplace. As far as the cob is concerned I've seen mention of an expansion barrier to prevent the cracking you mentioned , but I wonder how that would effect the heat transfer from the steel barrel to the cob and out into the room. Any thoughts?
Thanks, Vern

Great idea Peter I'll look into it and thanks. Sorry to hear about the testo and I wholly understand your wealth like you I am blessed with plenty of time and not so much money> I have already hauled my wood and am now processing it while hoping to get some sort of rocket heater made as I only have about a third of what I normally use and I don't want to resort to oil if at all possible. Thanks again Peter for sharing I really enjoy learning from your wok

What i will need to change in all system?
