calorific) value of fuel for efficiency calculations in US, UK and many other countries. Germany uses low heat (net calorific) value basis, implying that for an identical boiler, the stated efficiency will be higher. There are two methods of assessing boiler efficiency; 1. Input – output or direct method, and 2. Heat loss or indirect method.
