Results of a controlled cooking test series conducted in Uganda by Erika Tyler from Columbia University's Department of Mechanical Engineering, and presented at the 2009 Partnership for Clean Indoor Air Forum, showed a 38% fuel savings without using the pot skirt and a 95% preference over the local Uga stove.

Tyler maintained conditions as much as possible while comparing the StoveTec rocket stove, the Ugastove manufactured in Kamapala Uganda, and the three-stove fire. Two sets of tests were completed with all three cooking options in 30 households. Fuel consumption, usability of the stoves and stove preferences were logged.
