Rocket Stove Mass Heater





Introduction: Rocket Stove Mass Heater

Le combustible est exposé à une chaleur très intense.  La chaleur augmente dans la cheminée interne isolée ce qui complète la combustion.  Lorsque le rocket atteint sa chaleur normal de fonctionnement, il n'y a pas de fumée qui s'échappe de la cheminée.  J'ai profité de l'expertise d'autres constructeurs de rocket stove sur internet pour proposer ce modèle que j'ai personnalisé à quelques points.

    Hello Seniortrader. Very nice looking build there. Would you mind telling me what size tank you used for the build and some other basic dimensions? Any modifications you wish you would have made? I am planning on building one very similar to this soon.


    The tank is made from a 40 gal water heater tank. The intern chimney is a round 3/16 by 4.5 by 38 inches steel tube. It si welded to a 4X4 inches square tube.  I used a piece of 4 inches diameter diesel truck muffler to connect the tank to the exhaust pipe. The feeding part in front is kept in place by the bracket i made... It is very usefull if you want to use more than one kind of feeder but if not i would recommand to weld the feeder directly on the heat chamber.  If i had to do it all over i would use thicker peice of metal to get as much mass as possible.  And another thing... As i'm not a pro welder, i would graind all the welds before taking pictures of it..:) 

    Hoping to see some pics of your project very soon!!!


    Hi, I hope you are still fabricating? What is the distace between the top of the chimney and the underneath of the top? and is it critical? Could you split the fire box with a plate which would keep the fire on the top and fresh air sucked in below? Terrific project, well done ST

    I like what I see! My dad used to make these out of old kerosene barrels. How long did it take you to make? Have you ever heard of a company called Dragon Heaters? They have cores for sale seems much easier to put together than brick.

    to expensive. 50 bucks 4 the barrels plans.

    Hi billyj789,

    It takes me one day to cut the parts and about 3 hrs to weld everything.

    I did not know about dragon heaters til now and i like there desings. The rocket stove is well known around the world for it's low operation cost and the effectiveness of it's burner.

    I saved a lot of money by switching to this.


    Absolutely Great!

    I have a fireplace but of course it's not very efficient. I've though about getting a wood stove insert but this looks better to me. Since it seems the exhaust pipe is low it shouldn't be a problem to run it up the chimney.

    I might give this a try if I can get someone to weld for me.

    I see how this is a rocket stove, but I don't see how this is a mass heater. It looks like you run the exhaust outside directly after the combustion barrel. Aren't you losing a lot of heat by not routing the exhaust through a mass?

    How is the paint lasting? What kind of paint is it. Is it a specific heat resistant metal paint?

    The Rocket Mass heater tends to burn really hot I believe.

    This project is a really nicely built one. I like your attention to detail a lot. Thank you for taking the time to do this, especially the drawings etc..

    I hope you home and workshop area is toasty warm now.

    Your english is fine too. We get it... LOL... It's better than my French I can promise you that...

    Hy David, Thank you!

    This is a high heat bbq and stove paint, It still look fine ..( i forgot to light the stove outside the first time, can you imagine the smoke in my garage) The heat is great, I mostly use the gravity pellet burner and keep it at the minimum burning rate ...
