Philips Fan Stove (Model HD4012) burns pellets made of sawdust, peanut shells and other agricultural waste and biomass. It features an inbuilt fan and a rechargeable battery that forces air into the top and bottom of the combustion chamber, leaving a smoke-free wood-fire within very little fuel used.
For 2018, this stove model is discontinued.
The stove was designed by Paul van der Sluis, a researcher at Philips Research Laboratories in Eindhoven. The example was manufactured by Philips in Lesotho, used for a while in Zambia and then shipped to Lund Sweden for evaluation. Philips Fan Stoves were afterwards mass produced by African Clean Energy in Lesotho since 2011 and by Emerging Cooking Solutions also in Lesotho.
Intellectural Property Type
User Provision Model
Emerging Cooking Solutions produces the stoves and sells them to distributors such as Copperbelt Energy Corporation, First Quantum Minerals, Sandvik, and SKF.
Distributions to Date Status
The exact number of distribution to date is unknown, however, and for 2013 over 15,000 stoves were sold.
Thermal efficiency (%)
PM emissions (g/MJ delivered to pot)
CO emissions (g/MJ delivered to pot)
Time to boil (min/L)
Design specifications include the stainless-steel body with a ceramic-inner combustion chamber. At the bottom of the combustion chamber, there is a knob, an inbuilt fan and a battery that is charged either from the grid (when available) or using a solar charger. It weighs 4.6 kgs and its dimensions (LxWxH) in cms are: 33 x 35 x 33.
The stove has a 1-year warranty and expected lifecycle is 5 years.
Manufacturer Specified Performance Parameters
This stove meets the energy needs of off-grid families within a cost-efficient, sustainable and market-driven solution. Due to its integrated fan and battery, it utilises minimal wood chips (fuel) and the flame can be controlled by the user. Further key features can be seen here.
Vetted Performance Status
The testing results for the stove are summarized in the Clean Cooking Catalog.
Keep all flammable items away from the surrounding area of the stove, and do not enclose the area you are cooking within; proper ventilation is always required. Do not touch the body of the stove while in use.
