brilliant build. i've seen these in person even slept on one for a week. when built right they are safer than a conventional woodstove and use a quarter to one tenth of the wood of as the most efficient modern woodstove. they also emit no smoke after a few minutes when burning dry wood,and the biggest positive is they stay warm long after the fire is out, thereby saving tons of wood and time feeding it at night. they also cost far less than a brand new woodstove, although they are quite laborious to build, and you do need to be at home for a good six or seven hours to charge up the thermal mass, but the barrel does put out a lot of heat right away off the top, I've had it reading up to seven or 800°.
Either it gets hot enough to start the bench on fire or can't be enough to heat the house....seems to me. I can't help it. Just seems like one of those "Don't try this at home" things.
The bench is made of rock, clay, cement and plaster. None of these materials burns at the temperatures involved. The bench under the pillows never gets too hot to touch but it is so massive that this is a very significant thermal battery. Also, we have passive solar heat in the second story that heats the upstairs where we sleep so that it says plenty warm.

Thanks for the insight!
That’s so clever!
Thanks. We thought they did a brilliant job with that, too. :)
Burning pressure treated lumber from building materials can make you sick.
Right. I don't believe they are pressure treated.
We don't burn any pressure treated, OSB or plywood in the Rocket Mass Heater.
