The net calorific value (NCV) is calculated from the GCV using unique calculation formulae, and is dependent on the standard required. NCV is generally reported on an 'as received' basis. NCV determined by constant volume delivers a slightly higher result than NCV performed under constant pressure.

There are two kinds of calorific values: Gross Calorific Value (GCV) and Net Calorific Value (NCV). While NCV accounts for the heat required to evaporate water and hence offers a more useful estimate of the available energy, GCV adds the heat released during the condensation of water vapor created during burning.

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.
