Stove information

Model: Improved
Application: Households
Type of stove: Kitchen
Produces biochar
Fuel: Wood


Materials: Metal
Designer: CEHEEN
Construction method: Made in Fabrication Workshops


Availability: Commercially available
Distributors: A socio-economic impact assessment revealed that since the dissemination of the improved stoves in the two pilot communities, up to 60% of the people have directly and indirectly gained employment.

Following a training programme organized by the centre for some women’s group, six fabrication workshops have now been set up. In one of the workshops in Benin, a fabricator is making 3 to 4 stoves daily providing a monthly income of US$196 (~24000 Naira).

Start date: Sat 01 of Jan., 2000
Project/Program or commercial distribution: Centre for Household Energy and the Environment embarked on a twoyear study into household energy situation in Nigeria with key emphasis on environment, health, gender and poverty. The two communities selected were; Oghara – a typical rural community, and Benin – a peri-urban community. Both are located in the rain forest ecological zone in the southwest Nigeria.

Egaga is a local device used to support cooking pots over traditional open fires in parts of rural and urban Nigeria. Identifying the need to accommodate people’s traditional beliefs, CEHEEN chose a compromise which provided new, visible, significant advantages and also maintained key factors associated with smoke, tastiness and preservation of food. As an improvement on the crude tripod egaga, which is usually supported by stones, and into which can be fed uncontrolled amounts of fuelwood, the team developed a variant semienclosed egaga metal stove

Number of stoves sold or distributed: 3274


Efficiency testing method and who did it: egaga metal stove(Figure 1), which conserves up to 60% of the heat hitherto dissipated, while using limited amounts of fuelwood. Before final adoption, two existing stove models were tested against the improved egaga: the fixed mud stove, and the conventional tripod egaga stove (Figure 2). The tests were based on; durability; portability; thermal efficiency; emission reduction; affordability; and replicability. In the test, the improved egaga scored above the other two models used in every way. While it took the improved egaga a record time of 12 minutes to bring 4 litres of water to boiling point, it took the fixed mud stove and open fire 18 and 19 minutes to perform the same task.

Fuel saving: 40%
Duration of cooking session: 12 minutes to bring 4 litres of water to boiling point,

Notes: The improved egaga stove project is in its second year, and initial funding has been made possible by grants from the U.K based Ashden Trust for Renewable Energy and the Whitley Awards Foundation.
