Testing Stoves with the Water Boiling Test and the Controlled Cooking Test

“Since Proyecto Mirador’s inception in 2004 we have been indebted to Aprovecho Research Center for its expert involvement with regard to stove design and testing. Aprovecho’s laboratory testing provided the technical proof needed to secure Gold Standard carbon certification thus helping Mirador to achieve financial sustainability. Our stove’s efficiency increased significantly as a direct result of Aprovecho’s modifications, which positively impacted our beneficiaries’ lives (and Mirador’s bottom line) by further reducing fuelwood consumption. Aprovecho’s team has been creative, nimble, and professional at every level.”

ARC specializes in testing biomass cooking stoves. We test stoves to understand how they function, to compare stoves, and to improve performance. The Water Boiling Test (WBT) and the nine metrics in the ISO/IWA Tiers provide the project manager with a holistic picture of emissions, fuel use, and safety.

Will the stove be successful in your region of the world? Will families be happy cooking with the stove? How much will they pay for it? Is the firepower, the height, the turn down ratio what cooks require? The Controlled Cooking Test (CCT) is designed to answer these important questions.

The test has local cooks preparing the regional foods using their fuel, their pots, and their methods of fire tending, etc. The CCT is performed with the same emissions hood used for the WBT. In this way, very accurate data on fuel use and emissions is obtained (including black carbon). ARC specializes in using both tests to evolve market viable, locally appropriate stoves that meet the ISO emissions standards protecting health.

Services Offered and Prices

For $3,000 ARC will test your cook stove in our Oregon lab and provide an ISO certificate of Tier performance ratings. The same tests results can be submitted to the Gold Standard as part of the carbon credit requirements.

For $8,000 plus expenses the ARC team will conduct a CCT at the project site.

Please contact Mike Hatfield for complete descriptions of the testing process.
