I'm desperate for help in building a small/tiny, preferably all brick RMH to get me through winter.
The past year(s) both Peter van den Berg and Matt Walker have graciously offered help. but Life keeps throwing up hurdles. I'm currently in a cast and one-handed due to an accident, and will most likely remain fairly incapacitated for the foreseeable future. I was going to install a stove by Matt, but simply can't do all the necessary work right now (will still buy the stove, Matt!). I now need a small RMH in the North-facing annex that will function as a buffer against (most of) the cold.
The most important aspect is that it can not rely on a flue to burn and should have near-zero exhaust. This because the flue's outlet will be situated between buildings, ergo loads of wind vortexes, and because my neighbors will counter any attempt at burning wood as soon as they smell a whiff of smoke. I used to rely on a tiny potbellied Taiwanese wood stove, but had to stop using it 5 years ago when my neighbors started complaining after my partner passed away and refurbishing plans came to a grinding halt.
I have about 50-60 fire bricks as well as a stack of bricks outside, and also a bunch of small hexagonal concrete pavers. There's also a yard full of junk that may throw up items I need, like steel lid-less ammo boxes, old glass laundry machine doors, etc. Due to the flue outlet (hole in the wall) the stove can either be built right underneath, or in a corner with a pipe going up and then horizontal for about 1 meter.
It doesn't have to be pretty, as long as it's functional for at least this season, in the hope I can get to building a permanent stove the coming year.
Any help and ideas would be appreciated so, so much, because in my current condition I'm not looking forward at another winter with inside temperatures of 12C or less.
Welcome Saskia to rocket stove central. Lots of great people to help you out here and help to answer your burning questions.
Up front, I need to say that your statement about not relying on a flue to burn and not producing even a whiff of smoke is asking a lot even for a super efficient dragon to overcome.
An outer insulated chimney is really important to help maintain a good reliable draft. However, to help overcome this, a bypass is definitely something you'll want to strongly consider.
A T pipe with a fan could also be used alone or in conjunction with a bypass to ensure reliable draft.
When you first light up your stove and often during reloadings, there is a bit of smoke that comes out the chimney. Even 'clean' exhaust has a mild smoke scent to it. So depending on how much your neighbours complain, it still may be an issue.
I would recommend a stock 6" J tube to get you up and running for a simple and quick as possible build.
Lots of people here have posted their builds in the forums and lots of really good info in The Rocket Mass Heater Builders Guide.
Depending upon your skills, tools, materials and determination, it can be possible to get one built in a short period of time.
Photos and specific questions are always a big help so that we can better see what your working with.
