Rocket stove dimensions7/23/2023 To secure the bricks of the heat riser I totally covered them up with a thin layer of clay mixture as you can see in the picture. ![]() The height of the heat riser is a fundamental parameter as it must create draft and it will determine the total height of the stove. I placed the bricks over the burning chamber rotated by the shortest side because this area is subjected to breakages and I left the necessary space to host the water boiler. As showed in the picture I placed the bricks using a pattern in order to achieve the same section of the burning chamber inlet by cutting only one brick that you can recognize by the different color. The heat riser is the most important part of a rocket mass heater, this is the engine, it creates the draft necessary to suck the air from the feeding chamber inlet and push the gases through the exhaust duct until the chimney. Remember that to guarantee a good operation need keep about the same section for all the ducts of the stove. The feeding chamber is almost concluded, it's 35" long with an 8" x 7" inlet. Instead of the expanded clay you can also use another inexpensive material as wood ash for example or insulating firebricks but in that case you will need to change the position of the bricks. I filled the empty spaces between the bricks with the expanded clay to ensure the maximum insulation of the burning chamber from the floor and from the rest of the stove. I didn't use any clay or cement inside the burning chamber because it would surely come off after the first use but I used the clay mixture to secure the bricks from the outside. ![]() I choose thick bricks because they can store a large amount of heat necessary when you want to use your stove as a oven. I used 9" x 4 1/2" x 2 1/2" common bricks to build the base and firebricks with the same dimensions for the areas subjected to high temperatures in order to avoid breakages. The disposal of the bricks is studied to reduce the contact between the burning chamber and the other bricks allowing the maximum space for insulation. The dimensions in the picture are approximated to the nearest inch for convenience. The picture shows how to place the bricks to build the base for an insulated burning chamber this is where you put the fuel and where it will burn. thin metallic wire mesh about 65" x 40".about 70 refractory bricks 9" x 4 1/2" x 2 1/2".thermal battery: the bench stores the heat and releases it slowly also when the stove is off.possibility to use long wood logs (about up to 24").cooking inside the burning chamber (pizza, bread, barbecue, etc.).cooking on the top of the barrel (boil water, prepare soups, chestnuts).Take this plan as a hint and adapt it to your needs or to the material you already have, remember that the sizes are approximated to the nearest inch, naturally you can change the shape of the bench or cover the bricks with cob if you prefer. In this article I will explain you in 6 steps how to build this simple rocket mass heater made of bricks and rock blocks.

Without base: ~22 poundsĬare: Treat rocket stove like a cast iron pan. The Optional Removable Grill Attachment (click here) - 8” or 12”, 3/16” thick grill grate. To stow away, loosen threaded bolts, remove Rocket Stove, collapse end plates and side plates, and secure together with a stainless steel wingnut and bolt. There are two threaded nuts adjacent to one another that have thumb bolt to tighten the rocket stove to the base. Once the base is assembled, place rocket stove in slotted space. This easily assembles together to create a solid base for your rocket stove. The base is 12” wide and 12” deep and sits the rocket stove 6” off the ground. Throw a cast iron pot on the grill and cook anything! ![]() Let’s talk about this AWESOME rocket stove! This is the perfect accessory to an off grid meal.
