- A wood stove is a heating appliance capable of burning wood fuel and wood-derived biomass fuel, such as wood pellets.
- Wood stove are usually made using a combination of metal(iron) and bricks
- Most stoves are connected or have some type of ventilation system
- Popular wood stoves include:
- Boilers, Chimenea, Pot-bellied stoves and fire places
- The traditional stove makes use of stones (mapfihwa) to elevate pots
- In the early nineties the ‘tsotso’ stove was introduced and became popular
- Tsotso are dry twigs of trees which are hanging onto live trees or have dropped to the ground surface.
- These are collected and burnt in a specially designed stove to give heat energy used for cooking or boiling water.
- The stove can be made from mud or clay or from scraps of metal to a structure that will act as a kiln or furnace.
- When the twigs are put into these stoves and are lit, the stoves are closed at the mouth and the heat is trapped inside.
- Smoke escapes through an opening to which a pipe acting as a chimney is attached.
- Dried cow dung can be used in place of the twigs in such stoves as is happening in India.
