The 3 types are;cast iron or steel stovesmasonry heaters (with ovens)hybrid stoves or heaters such as the rocket mass heaterDepending on your application, each stove type [...]

If you don’t want you’re stove to go cold immediately after the fire is out, you need to store some of the heat from combustion. A wood-burning heater's ability to capture and store excess heat for gradual release later, to a large extent, is governed by the materials used. There are several important physical properties [...]

Users often want to capture excess heat from burning wood and then have it gradually released later, overnight for example, when no one is tending the fire. One of the simplest ways to do this is by heating a significant amount of thermal mass (water, clay or “cob”, brick or stone), from the exhaust after [...]
