Third Party Field Tests
The EcoZoom stove has been tested by third party experts to ensure they are safer and more efficient cooking solutions. Experts test the speed of cooking local foods, ease of use, fuel consumption, emissions released, and response of the cooks. EcoZoom repeatedly performs well in third party testing of manufactured cookstoves. The most notable reports to date, completed by USAID and the Millennium Villages Project, are summarized below. The reports were completed before the creation of the EcoZoom brand and thus feature the previous brand name of StoveTec. EcoZoom is the exclusive distributor of Aprovecho designed stoves in developing countries, all future testing in developing countries will feature the EcoZoom brand.
USAID_Berkeley Air_Dadaab, Kenya: The results show that EcoZoom has a fuel savings of 54% while cooking 7% faster than the open fire. The EcoZoom stove was also highly recognized by cooks as being the most fuel-efficient, the safest, the most durable and the easiest to use. The stove was the most preferred in 2 of the 3 camps, coming in second in the other. This table, from page 5 of the report, shows results for several stoves that were tested. The results listed under StoveTec are for the EcoZoom stove.
USAID / Nexant (Haiti):The EcoZoom stove was the most efficient, saving 50% of fuel over the open fire without use of the fuel saving pot skirt, saving cooks $0.15 for one meal and being the most preferred stove.
Millennium Villages Project (Uganda and Tanzania): This study was the result of the partnership between Columbia University and the United Nations Development Programme. The EcoZoom stove saved 39% of fuel (without using the pot skirt) while being the most preferred stove by 96% of households. The EcoZoom stove did equally well in Tanzania averaging 39% fuel savings depending on the meal, while again being ranked as the most preferred stove by nearly two-thirds of the respondents. This graph shows stove user preferences in Tanzania. Again, StoveTec on this graph is EcoZoom.
