A rocket stove mass heater

In the background there is a mass heater.
This mass heater is powered by a rocket stove and is completely encased in 'cob'.
Cob is a cement like material made from one part clay, three parts sand and one part straw, add water and mix.
This type of mass heater is only fired for about two hours. The cob holds heat all day
 

A campstove that will last more than a lifetime. A rocket stove like the one below  will be handed down for generations.

Rocket stoves are more efficient than an old style wood stove.
One Big difference is the rocket stove is so efficient it burns almost all the smoke, creosote and ash.

A rocket stove achieves efficient combustion of the fuel at a high temperature by ensuring a good air draft into the fire, controlled use of fuel, complete combustion of volatiles, and efficient use of the resultant heat.
It has been used for cooking purposes in many energy poor locales (notably Rwandan refugee camps) as well as for space and water heating.
 
A rocket stove's main components are:
    Fuel magazine: Into which the unburned fuel is placed and from which it feeds into the combustion chamber
 
   Combustion chamber: At the end of the fuel magazine, where the fuel burns
 
   Chimney: A vertical chimney above the combustion chamber to provide the updraft needed to maintain combustion
    Heat exchanger: To transfer the heat to where it is needed (cooking pot or other load).
 
The fuel magazine can be horizontal, with additional fuel added manually, or vertical, with fuel gravity fed. As the fuel burns in the combustion chamber, convection draws new air into the combustion chamber from below, ensuring that any smoke from smoldering wood near the fire is also drawn into the fire and up the chimney. .This is the best place to buy a Rocket Stove!
A rocket stove mass heater or rocket mass heater, is a space heating system developed from the rocket stove, a type of efficient wood-burning stove, and the masonry heater. Its fundamental characteristics are an insulated combustion chamber where fuel (generally wood) is burned with high efficiency at extremely high temperatures, and a large thermal mass in contact with the exhaust gases which absorbs most of the generated heat before the gases are released to the atmosphere.
 
In the earliest developed form, wood is gravity fed into a "J-shaped" combustion chamber, from where the hot gases enter a heavily insulated fire-brick or ceramic refractory vertical secondary combustion chamber, the exhaust from which then passes along horizontal metal ducting embedded within a massive cob thermal store. The thermal store is large enough to retain heat for many hours and may form part of the structure of the building. They have proved to be popular with natural buildings and within permaculture designs; they are normally self-built and are not yet recognized by all building codes which regulate the design and construction of heating systems within buildings.
The chimney can be insulated to increase the temperature and improve combustion; according to studies,this can increase efficiency by up to two percent. In a rocket mass heater, the heat is passed to a heat exchanger to ensure the efficient use of the generated heat.
For cooking purposes, the design keeps the cooking vessel in contact with the fire over the largest possible surface area. A pot skirt can be used to create a narrow channel that forces hot air and gas to flow along the bottom and sides of the cooking vessel. Optional baffles guide hot air and flame up the sides of the pot. For space heating purposes, the heat is transferred to a heat store which can, in some cases, be part of the structure of the house itself. The exhaust gases then pass out of the building via the chimney.
The design of the rocket stove allows it to operate on about half as much fuel as a traditional open fire, and it can use smaller-diameter wood. If the stove is insulated and raised from the floor, the danger of children burning themselves is reduced. Some more recently designed rocket stoves are self-feeding, using gravity to add fuel to the fire as required

This is something we need to talk about.
A rocket stove mass heater can heat a home, a greenhouse, water and will easily heat a hot tub at your cabin.

    1. An older design rocket stove cooking breakfast
    2. This is a great little cookstove
    3. Arrows show the direction the exhaust travels
    4. Fire this one up !
