Replacement Components

Replacement for all the components of the stove is available.


1 year warranty

Manufacturer Specified Performance Parameters

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.

Vetted Performance Status

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.
