Heat of combustion - Wikipedia

The higher heating value takes into account the latent heat of vaporization of water in the combustion products, and is useful in calculating heating values for fuels where condensation of the reaction products is practical (e.g., in a gas-fired boiler used for space heat). In other words, HHV assumes all the water component is in liquid state

The fuel-air mixture burned in the combustion chamber quickly releases its heat to the heat transfer surfaces surrounding it, and the hot flue gas escapes through a draft hood into the flue. The role of the draft hood is to prevent too great of a flue draft or a back draft in the flue system from affecting the combustion process.
