Jan 01, 2021 · The heat loss from the boiler shell is normally a fixed energy loss. With modern boiler design this may represent only 1.5% and the gross calorific value at full rating, but will increases to around 6%,if the boiler operates at only 25% output. Repairing or augmenting insulation can reduce heat loss through boiler walls and piping. 13.5.
