Test information
Test details
The ethanol stoves were tested using the 2003 UCB Water Boiling Test (WBT). The first phase of each test consists of a high-power analysis in which 2.5 or 5 liters of water are brought to a boil in the standard 3 or 7 liter pots. In this case, only the 95% fuel burned in the CleanCook stove produced a high enough firepower to boil the 5 liters, so the other test series were conducted using 2.5 L of water. Each high power test was performed twice with the stove body starting cold and then again when hot. In the low power phase of the test, the 5 liters of water was simmered at about 3 degrees C below the full boiling temperature for 45 minutes.
