[Stoves] Calculation help

[Crispin Pemberton-Pigott]

Yes that us the correct enthalpy but not all of it is 'lost', by definition. The definition of 'lost' is taken to mean 'unusable heat', not actual losses. 

Any gas below 100 C is not going to boil much water so it is considered lost if below that temperature. 

So be careful when calculating the actual heat in something (referenced to 0 C) and losses. Usually LHV is the usable heat above 100 C for most things and above 150 for commercial heat exchangers in the USA.

Crispin
