Calculating NCV/GCV from elementary analysis (FNCVCALCELEM) The default method for NCV/GCV calculation according to FDBR implemented in Ebsilon uses empirical formulae that are based on elementary analysis. For logical reasons it should therefore only be used for solid and liquid fuels where only an elementary analysis can be specified.

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.
