There is a video on richsoil.com, where someone burns the paint off a barrel, and then puts a simple pipe inside the burning barrel, and the gases REALLY burn like a rocket! Is this how the gases are supposed to burn inside the rocket stove mass heater as well?
Radu Marius wrote:These are my dimensions: The heat riser is a 6" metal pipe, 35" tall. It has a 10" metal pipe on the outside, and in between it has as an insulator, compacted pulverized refractory bricks with a little bit of clay, just to act as a bonding agent (i had a lot of refractory bricks that weren't good anymore, they would break fairly easily). The thickness of the insulator is roughly 2", equally distributed between the pipes.

Sounds to me like you are on your way to getting your RMH in order.
As a somewhat verbose poster myself, I've found it useful to use the return key to start new paragraphs - neither the tab key nor multiple spaces register when you submit a post.
If you post a dense block of text you will have people reading your info with about as much care and attention as you gave to Ianto.
Speaking of density: be aware of what kind of "fire brick" you are using. Some firebrick is made to add thermal mass to wood stoves. The other, insulation, "fire brick" (more properly kiln brick) is used for insulating kilns or brick ovens. The insulating stuff is very white, very light with large bubbles throughout.
