Annex 6.E Determining seasonal boiler efficiency

2014-9-30 · To convert from net efficiency to gross, multiply the net calorific value for the boiler efficiency by the conversion factor for the appropriate fuel, e.g. a LPG boiler 80% net efficiency x 0.921 = 73.68% gross efficiency.. The boiler efficiencies, measured at load and at 30%, are used as the basis for calculating the seasonal boiler efficiency as described by equation 1 below.
