Heating Value. The lower heating value (LHV) or higher heating value (HHV) of a gas is an important consideration when selecting a gas engine or CHP plant.Gas engines efficiency is typically quoted based upon the LHV of the gas. Whenever a hydrocarbon fuel is burned one product of combustion is water.

Learn More### Lower and Higher Heating Values (LHV and HHV)

Lower and Higher Heating Values (LHV and HHV) There are two different types of heating value, which are the lower heating value (LHV Lower heat value) and the higher heating value (HHV Higher heat value).By definition the higher heating value is equal to the lower heating value with the addition of the heat of vaporization of the water content in the fuel.
