WebbIn fact, these manufacturer values do not take into account the unavoidable losses in the physical system and are therefore more of a theoretical nature. However, when it comes to retrofitting or building a new building, it is crucial that old non-condensing heating systems often do not exceed 70 to 80% of the gross calorific value.

WebbNotes: The lower heating value (also known as net calorific value) of a fuel is defined as the amount of heat released by combusting a specified quantity (initially at 25°C) and returning the temperature of the combustion products to 150°C, which assumes the latent heat of vaporization of water in the reaction products is not recovered.
