Any body here ever use or build a ROCKET MASS HEATER or ROCKET STOVE? From what I am reading they seem to be a real fire wood saver. Fire it and heat the mass up and it lets off heat for several hours. If there are any users out there with feedback on these type heaters, that would be a great help. I was thinking that the mass heater would be good in a greenhouse for winter growing. Do not have a greenhouse yet but I am kicking around the idea of one in the future.

I take my woodstove and stack bricks all the way around it to add mass,, it really helps to hold and slowly release the heat

Stan O, that sounds like a really simple improvement for those who already have traditional wood stoves. It definitely sounds like something worth considering.

Rocket Stoves are indeed really worthwhile. Gets every ounce of energy
out of the combustion process and leaves much less in terms of pollutants, but watch out for CO (carbon monoxide)and make sure that the system is tight and well ventilated. All of that being said, I'm also interested in rocket stoves combined with TEG (Thermoelectric
Generators) Is anyone interested in this topic as well? Just curious?
We are just starting to mess with the TEG and TEC modules (Thermoelectric Coolers). Coupling the Rocket Stove and a TEG assembly
seems to be a good project...
