By carefully controlling the burn process, it captures wood at its charcoal phase before it turns to ash.

The unique inclusion of a water tank in the design means the Social Tawi and the Forest Tawi  are the only charcoal making stoves which can operate continuously. Like all our stoves, when run correctly the flame is virtually smoke free. It also burns dry brash, hedge trimmings and other waste wood. The hotplate and chimney front can be removed in seconds to convert the Social Tawi into a fire-trough.
