New RMH build

Well thanks again guys and gals. New rocket heater works awesome. A balmy 25 degrees here in Otter Lake Mi. and Im nice and toasty without the propane pain

Can you post a few more pictures showing your exhaust system?
Thanks

Its really basic. 2 6 in stove pipes come out of the barrel about 35 inches into a piece of 8 x 16 ducting. Then into a snorkel made of osb out a window

Thank you. Just looking at the picture I couldn't picture the exhaust. Now that I know it has two tubes, I don't need any more picts.
Why two tubes for the exhaust?
I'm curious, I'm still learning about rocket heaters...

Hi Joe,

Pictures are worth a thousand words...I keep saying it, and still get surprised.

Your system (please correct me if I am wrong) was aimed at having a RMH that heats up quick...

I assume your inner flue withing the barrel is that nice geometric cut fire brick?

How quick does this heat that space?

I think, now seeing it, and assuming you want a "low mass" fast heating system, that your choice for using a high heat resistant caulk might well be better...I am just worried it won't last. I have looked into some of the types we use for masonry heaters and soapstone stoves...it may serve you better if I can get my hands on the name of it...that is if its not proprietary...

After this is up for a while, give us a report of results and what you want to change...

Thanks again for sharing the adventure!

Im running a pretty huge J-tube about 9x10 square made out of insulating fire brick comparable to cast refractory so I needed enuf exhaust to handle that. Burns insane compared to my 4.25x4.25 J-tube made of reg fire brick. I threw this together to replace My first little one I built last year. Compared to Tim the Tool man Taylor Im Don Garlitts. In the next 10 days Im going to make some Improvements. Most of the peeps here are into heat storage and blah blah. Im going a different route. I want to produce intense heat for short periods of time partly cuz of my schedule of working in my garage too. Im going to supercharge my rocket by installing a duct fan in the exhaust on a reostat so I can run it as hot as I want. Of course Im just a dumb Polack. So expect my results to go way beyond what Im saying.
