The high heating value includes this energy. The lower calorific value doesn't include the energy released in condensing water. This is why a gross calorific value is higher than a net calorific value. HHV = water vapour is condensed = more heat is recovered. LHV = water vapour remains as vapour – less heat is recovered.

While the NCV only reflects the energy content of a fuel, the GCV indicates how much thermal energy can be obtained in total by the heating system. Condensing technology uses the energy of the combustion gases to generate additional heat. The higher the NCV and GCV, the better for energy efficiency. Conventional heating technology, on the other ...
