The REDI group has developed stove designs an' is now promoting the two stoves described below.
1. The Miha (Micuta/Haas) Institutional Stove used in Kenya and other countries.
This patented multifuel stove can be manufactured in sheet metal, in clay or in bricks using standardised metal components. The production costs are relatively low when compared to improved stoves. Fuel efficiency rate in stoves built according to the designs and correctly operated are reported to be around 45%. Specific wood consumption is 60-70 gms wood per kg of food cooked. In comparison with the current inefficient cooking methods of community cooking, the stoves can save 70-90% of wood fuel. Food simmers for 1 to 1 1/2 hours after the flames have gone. Metal stoves have double walls filled with sand or soil as insulation. MIHA patented kerosine burners or local LPG burners can be fitted to the stoves. REDI grants patent rights and technical know how to qualified local enterprises.
2. MIHA (Michuta/Haas) household, multifuel, multipot, sheet metal stove "Marek".
This patented transportable stove can be fired with any available fuel, preferably with wood, agricultural or urban waste. It is a one hole stove on which three different diameter pots can be used. Its production requires 6 kgs of ordinary steel sheet, five kgs cast iron (or 3 kgs sheet metal) for the fire box and 2 man days work on small scale or 1 man day work on larger scale production. The stove works with cooking pots designed for this purpose. Its fuel efficiency rate is about 45%. Its specific wood consumption is about 60-80 gms wood per kg of food cooked. With cast iron fire box, food simmers for about 1 hour after flames are gone and it can therefore be used in enclosed premises. REDI grants patent rights and know how to qualified local enterprises.
