Boiler evaporation rate

WebJun 20, 2015 · The evaporation rate depends on the surface area of your brew kettle, the rate of boil (e.g., rolling boil), and to a lesser extent, the altitude. A percentage can be accurate if you always boil the same volume in the same kettle at the same rate, but as soon as you change one of these variables that percentage will be wrong. http://www.cfbcboiler.com/what-are-boiler-efficiency-and-boiler-evaporation-ratio.html
