Ahh ok so would the system work better if i reduced the length of the pipe? im going to build a brick one this weekend and search for some oil drums and ducting! hopefully i can source the materials for free and that way i am not loosing out if i do something wrong.

Ahhh well that makes sense then thanks just out of information do you know what sort of temps you get out of a 6" system? and how do you work out the height of the burn tube?

Bret thats fine i think you are looking at the same one as me, Satamex that is not the one i mean, i was looking at one that was like the normal heaters but the exhaust just didn't go through a thermal mass. i made a tiny tiny version to try and see if it works (FYI a tiny version does not work although i can get suction there is not enough room for the burn) here is the link to my post about it (same post as this but with the mini one on)

Hi everyone

Im new to this forum, posted a similar post yesterday but i have made development today on my project.

I went about seeing if i could create a miniature working model of this burner i want to make, anyway i will cut straight to it, it didnt work. However this has not phased me and i am still going to continue onto the larger version, i do however have a couple of questions for anyone out there who has made any type of Rocket mass heater. (i have also added a couple of photos of my model as i think it looks pretty cool.

Will this model, scaled up actually work?
has anybody done this before?
what sorts of temperature do you get out of these rocket mass heaters?
how could i make it better?

ok so this model, the green tube is insulation for the inner tube (in the large version this will be an outer tube filled with insulation for the inner tube, its made out of copper pipe and 2 tin cans.

i could get a good suction going and it would burn outside of the tube and suck all of the flame in so there was a powerful suction there, but i think that is the problem, with it being such small scale it could not handle this amount of air rushing through and it just blew the flame out, also i do not think that there was enough space to burn anything there (maybe if if i double the size of the copper piping i would get it to burn but to be honest i'm not that bothered about a mini version of a rocket stove)

Thanks for looking and any feedback is greatly appreciated

Hi there

I am new to the rocket mass heaters and have done hours of research, however I don't want to spend much money making one, I want to heat a double garage using a "portable" RMH basically contained in an oil drum.

Will a heater with 4inch aluminium tubing get Hot enough to melt the alloy?

How much heat will a system like this produce? With no cob just an exhaust running along a floor for about 3m to the outside of the building?

Is there an equation to work out the heat produced by different size systems.

And has anyone ever made a self contained system like this and if so do you have plans for it please?

I'm sorry about all of the questions but I am planning on building it this weekend or next and just didn't want to waste my money.

Kind regards
Josh
