Net Calorific Value (NCV) and Gross Calorific Value (GCV) are both measures of the amount of energy released from a fuel when it is burned. The main difference between the two is that NCV takes into account the energy needed to evaporate any water produced during the combustion process, while GCV …
A fuel's GCV counts all its chemical energy but its NCV disregards that fraction (10% in the case of natural gas) that will be absorbed as latent heat. So when you calculate efficiency on the basis of NCV you get a higher value than if you had used GCV, to the extent that you see condensing boilers advertised as having over efficiency.

The calorific value defines the energetic content of the materials; it is the amount of heat a substance produces after complete combustion. You can express it as the gross calorific value (GCV) or high heating value. Also, the calorific value of a substance (generally, solid biofuel or food) is the specific energy of combustion for a unit mass.
