Documentation from the Empreinte database: Calorific value of propane = 46 MJ/kg (HCV) PCS/PCI ratio = 1.111 1 kWh = 3.6 MJ
We use HHV (Higher Calorific Value) and not LHV (Lower Calorific Value), because HHV is used as a conversion coefficient in invoices to convert the volume of gas used into kWh: it is assumed that the gas boiler recovers the latent heat of condensation.
