Almost any public warm water tap in Britain is accompanied by a sign saying Caution! Hot Water!
Some even read Very Hot Water, and provide even more serious warnings related to the water temperature.
The famous hot water taps in Heathrow airport must have scaled the hands of countless travellers. Can anyone tell me the logic behind maintaining a hot water supply at ludicrous temperature levels? I can see the anti-bacterial effect, but if it requires serious health warnings and causes scalding in turn, plus of course an enormous waste of energy, then I am not so sure.
Is there any reason, of is it just an insane cultural habit?
