[QUOTE="UNG, post: 560418, member: 8931"] Possibly!! This takes me back to my school and college days for some reason the specific heat capacity of water is something that has been stuck in memory A couple of graphs below for a comparison of watts and BTU's The first graph has the heat capacity in Kilo Joules for conversion 1 J/s = 1 watt [ATTACH type="full" width="458px"]17501[/ATTACH] I think you answered your own point here the output of a lot of equipment is down to how efficiently it uses what is put in. LED lamps are a case in point where the lumens / watt can widely vary across lamps of the same wattage [/QUOTE]
