Jiko Tosha

Country:
Kenya
Why to choose this solution?
The multi-purpose fuel cooking stove (Jiko Tosha) is an improvement on the currently available rocket stoves that use a single type of fuel, either firewood or charcoal. Jiko Tosha stove accommodates the use of several fuel forms, animal wastes, firewood, charcoal/briquettes, sawdust, biogas, and LPG. Any of these will work in the same stove unit. The Jiko Tosha stove was born out of shortcomings identified in the stoves existing in the market. Its advantages are that it reduces indoor emissions, provides a safe and healthy environment to the consumer, accommodates more than one fuel source according to availability, and ensures that the users have access to economical and affordable cooking technology.
Savings per day or production:
Savings of about 70% of charcoal consumption per day for a normal family.
Cost in money and in own time to construct:
Costs KSh 5000 (About USD 50).
Lifetime:
About 5+ years.
Maintenance needed:
F&M Industries does not have local technicians throughout Kenya. If a part of the stove breaks or gets damaged, it can be shipped to the F & M manufacturing plant in Nairobi for repairs. To move the product from one place to the other, manufacturers use an existing local transport system. Replacements for all the components of the stove are available.
Resources needed in use:
Manufacturers specify that this four-in-one clean-energy stove was designed to use gas, charcoal briquettes, sawdust, or firewood as cooking fuels.
Problems and limits:
Safety concerns when using the product with biomass or charcoal as fuel are primarily related to harmful emissions of carbon dioxide, carbon monoxide, and sulfur dioxide, along with gas leakage during use with gas fuel. Another significant safety concern is domestic accidents such as accidental burning or spill-overs.
