Customer can buy the Kuniokoa through a BURN credit, which requires an initial 50% deposit payment and the remaining must be paid interest-free in the following 2 months.
Rocket cookstoves with ceramic insulation such as the EcoZoom Dura, Envirofit G-3300, Envirofit M-5000 and EzyStove. Almost 90 competitive cookstoves can be found in the Clean Cooking Catalog.
Goal 7: Ensure access to affordable reliable sustainable and modern energy for all.
The Kuniokoa Stove is manufactured by a locally trained workforce at BURN Stoves´s Kenyan solar-powered factory. The manufacturing site consists of an assembly line and production batches of each part. For wire and sheet metal, pneumatic bending and clamping jigs along with welding and drilling jigs are used. Additionally, a hydraulic press is used for forming, press brakes for bending, spot welders for assembly and laser etching machine to make customized name-plates. A stamping-tooling developed by a company called Hiparter in China is used for the more complex metal-sheet parts to obtain BURN Stoves specifications.
Retail shops, middlemen, supermarkets, contracted distributors, partnerships with other product distributors. The main retail spots for shopping for Kuniokoa are supermarkets in Kenya like the Tuskys branches. Users can also obtain the product through the not-for-profit social enterprise LivelyHoods. BURN Stoves has additional chama networks, where the members sell the stoves in their communities for commission through credit options like the chama credit or BURN credit.
Exact number unknown. However, BURN Stoves has sold more than 400, 000 cookstoves since 2013 between their two main models: Jikokoa and Kuniokoa.

Manufacturers specify a high power efficiency of 37%, high efficiency cook top, light weight construction, 31% less fuel used, reduction of emissions by 72% and 55% of savings on firewood as their performance targets.
The Department of Chemistry Laboratories from the University of Nairobi conducted the approved simulation of the cooking process, the Water Boiling Tests (WBT). The tests showed above average values for the measures of:
- How efficiently a stove uses fuel to heat water in a cooking pot.
- Quantity of emissions produced while cooking.
The Partnership on Women’s Entrepreneurship in Renewables (wPOWER), under their “Where are the women in the energy sector” series, developed a case study on a project undertaken by BURN Stoves which explores the gender distribution in their production. wPOWER stated the key findings on BURN Stoves’s good manufacturing and distribution performance as:
- Policy: Providing a conducive working environment promotes women’s participation in the manufacturing industry.
- Education: Gender disparity in technical and skilled jobs needs to be addressed in order to advance the employment of women in different areas of manufacturing.
- Coaching and mentorship is vital in encouraging initiative and confidence in women employees.
The safety concerns associated with the usage of wood-burning cookstoves are primarily related with carbon dioxide, carbon monoxide and sulfur dioxide emissions.
Another significant safety concern is domestic accidents such as accidental burning or spill-overs.
