Jiko Tosha is a multi-fuel improved cookstove.
Jiko Tosha is a multi-fuel cookstove that can utilize LPG gas/biogas, biomass briquettes/charcoal, dried waste, and firewood as fuel for cooking. The design aims to tackle the issue of stove stacking, for which it integrates traditional components of a rocket stove with single-burner gas stove components. This product was developed and is currently being manufactured by F&M Industries Ltd.
F&M Industries Ltd and local Savings and Credit Co-Operative Societies (SACCOS).

Households and institutions in rural and urban areas.
The Jiko Tosha is manufactured in Kenya by a locally trained workforce. The manufacturing site consists of an assembly line and works on a batch production basis. Most of the parts are manufactured with power hand tools, welding machines, and a semi-manual pressing machine, except for the outer casing and combustion chamber that are manufactured using a sheet metal rolling machine.
This product currently holds a Utility Model patent and has a pending Industrial Design patent, both registered in East Africa by Kenya Industrial Property Institute (KIPI). F&M Industries is aiming to extend its patents to the World Intellectual Property Organization (WIPO) with the assistance of KCIC, where they intend to patent the product in several more countries that present market and copyright risks.

The Jiko Tosha is a multi-fuel cookstove that has a design that integrates traditional components of a rocket stove with single-burner gas stove components. It includes rocket stove components such as an insulated combustion chamber, elevated steel grate, ash collector and cast iron pot support; and single-burner stove components such as an LP burner and LP regulator. The design also includes a stainless steel adaptable fuel bed for briquettes and charcoal.

Manufacturers specify this four-in-one clean energy stove was designed to use gas, charcoal briquettes, sawdust, or firewood as cooking fuels. Specified performance targets for this product include fuel savings and higher cooking efficiency.
Testing carried out by the Kenya Industrial Research and Development Institute (KIRDI) on the stove performance determined that the thermal efficiency of the stove is at an average of 56% while using LPG as fuel, but when using charcoal the efficiency is at 33%. In terms of emissions, it was determined that while using LPG as fuel the CO and PM emissions are very low, but when using charcoal the emissions are average and fairly good respectively.
KIRDI concluded that the performance of this product is better compared to many existing in the market now, but recommends to improve the efficiency and CO emissions while using charcoal in order to achieve a Tier 4.
The safety concerns when using the product with biomass or charcoal as fuel are primarily related with harmful carbon dioxide, carbon monoxide and sulfur dioxide emissions; and when using the product with gas fuel is gas leaking.
Another significant safety concern is domestic accidents such as accidental burning or spill-overs.
Complies with the following cookstoves rating for the International Workshop Agreements as a streamlined process of the International Organization for Standardization (ISO):
- CO Emissions: LPG (Tier 5), Charcoal (Tier 2)
- PM Emissions: LPG (Tier 4), Charcoal (Tier 3)
- Thermal Efficiency: LPG (Tier 5), Charcoal (Tier 3)
F&M Industries Ltd is developing a bigger version of the Jiko Tosha named Biko Tosha Max, the aim of the design is to be better suited for institutional use.
