Competitive Landscape

Manufacturing/Building Method

The SCODE SP-FL Concrete Body is mass produced with SCODE´s input and is manufactured in regard to specifications provided by the Kenyan Bureau of Standards. SCODE’s warehouse in Nakuru fabricates the metal casing for the stoves whilst the ceramic components are sourced from Muranga. Per month the warehouse has a production capacity of 600 cookstoves.

Specifications: Maximum Pot Capacity: 40 L Dimensions (l/w/h): 360/300/240 mm

Product Schematics

Technical Support

Provided by SCODE or local trained builders.

Replacement Components



5 years.

Manufacturer Specified Performance Parameters

Manufacturers specify multiple fuel usage, low consuming fan, savings up to 50% of fuelwood, reduction by 60% of smoke emissions, easy to light, faster cooking than normal stoves and is long lasting as their performance targets.    

Vetted Performance Status



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.

Complementary Technical Systems

Due to the fact that the SCODE SP-FL requires a low power fan to assist with the combustion, an external power source is required. A solar panel or any other source of electricity can be installed to power the fan.
