The newest Rumford Cob Wall Fireplace is built into a Cob Garden Wall. The Rumford Cabin Fireplace is constructed almost entirely of Cob (an earth mixture of about 1/4 clay / 3/4 sand) and uses manufactured bricks only on the surface of the firebox. Fires are often burned with the sticks placed vertically against the back wall. Invented by Count Rumford during the time of Benjamin Franklin, this stove design features a shallow fire box area, with deeply slanted side which reflect the heat and radiate it out into the room. Rumford Fireplacesare quite efficient compared to a regular fireplace. Rocket Cooker Links Maple Syrup Cooker Midwest Permaculture Cement mortar would be more weather-resistant. The top of the stove is protected, when not in use, with a 3 x 3′ piece of plywood. The top layer needs re-mortaring every year or. Water is added until this mix is like “mousse” – sort of thick & fluffy, spreadable. The bricks are soaked, then the earth mortar is thinly applied. This makes the fire hotter, burning more completely (cleanly). We used an earthen mortar between the bricks ~ a clay/sand subsoil mix put through an 1/8th inch screen or window screen. It is considered a down-draft stove, and it burns cleanly, without smoke, using only sticks ~ once the fire is going.Įasy to construct, this stove has a 6″ stove pipe inside, with insulation (purlite or ashes) between the pipe and the bricks. The air is drawn down the short feed tube, then rise up the chimney to provide heat to cook food. The Outdoor Rocket Cookeris a basic Rocket Stove with a short feed tube where the wood goes, a horizontal burn tunnel, and a vertical chimney. It is uniquely sculpted with animal shapes ~ a turtle, a hawk with wings creating the sides of the seating area, and other beings woven into the design of the heater: whale, mouse, rabbit, frog, salamander, fish.Ĭheck out the for info on current classes and to Join the listsrve.

The heat generated can be piped through thermal mass, such as an earthen bench which can serve as a “thermal battery”, storing the heat while creating warmth and comfort. Rocket Stoves are very efficient wood-burning devices that generally use a J shape design for the combustion unit to achieve high temperatures and clean burn.
