Quite so. As has been discussed, several decades ago we accepted (really 'had to accept') that we had to wait fora kettle/whatever to 'boil' before we could 'do the washing up', or whatever.I just do not see it. .... Yet, as said, a lot of people in in a very small section of the world population do appear to think so. Whether that view is dependant upon their actual “average” usage pattern or just blind faith or a mixture of such then I have no idea.
However, people in the great majority of the 'developed' world have moved on from that. Th expectation now (and for a long time hitherto) is that amounts of hot water adequate for our 'needs' should always be available for immediate use - something which is achieved either with 'stored hot water' or with an adequately powerful means of true 'real-time instantaneous water heating' (a combi or an electric water heater of at least 10 kW or so).
As we have both said, there has to be some reason why "a very small section of the world population" seem not to have 'moved on' from those ancient 'expectations'. I doubt that their 'usage patterns' will differ appreciably from anyone else's so I suppose it must come down to some 'different way of thinking' ('cultural differences' or whatever) - but, like you, I don't really have much of an ideaas to 'what'!
Kind Regards, John
