Direct and Indirect efficiency in boilers

Fuel-to-steam or fuel-to-water efficiency is a measure of the overall efficiency of the boiler. It accounts for the effectiveness of the heat exchanger as well as the radiation and convection losses. For space heating boilers and in the BTS-2000 testing procedure, this type of efficiency is called "thermal efficiency." It is an indication of the true boiler efficiency and should be the efficiency method used in
