HHV: Higher heating value: the heat of vaporization of the water is released and becomes part of the heating value. Lower heating value, LHV :heating value in which the water remains a vapor and does not yield its heat of vaporization. Thus the energy difference between the two values is due to the heat of vaporization of water, HHV = LHV + hfg
