Would LHV calculations discount, say, condensing gas furnaces, which recapture most of the latent heat of fusion of water vapour in exhaust?

Otherwise, what's a typical percentage difference between LHV and HHV efficiencies?

Right, condensing furnaces recover the heat of evaporation (not fusion).

The difference for natural gas is about 10%.
