100A [domestic] supply, main switch, EV chargers, hot tubs, electric boilers and diversity

psychicwarrior

As the cash-cow climate change crusade gains more momentum and central electric boilers take up [again], along with hot tubs, electric showers (though they might be fed from boilers), induction hobs …  then  there is battery EV [charging] being foisted for hours at a time and so on.

In this new world order once everyone is converted, will supply and switching diversity be easier to assess (if it ever was not)  ?

    Likewise induction hobs if anything are more efficient than conventional ones, so (over conventional time at least) shouldn't be any more onerous a load than a conventional resistive electric hob, which we've manage to cope with OK.

    If you want hot water from electric then a simple off-peak immersion in a cylinder (pressurised if you wish) works fine with no great increase in maximum demand - as the French typically do on a meagre 30A or 45A single phase supply.

    If you're charging an EV overnight, then it doesn't have to be at 32A - 16A or even 10A will reach full charge by morning just the same. Or even better use the smart meter to co-ordinate large loads like that with the available supply (taking into account both local distribution and national generation).

    Electric boilers for central heating are to my mind a daft idea - I certainly don't know of anyone that's pushing them from an environmental point of view. Likewise outdoor hot tubs are likely to go back out of fashion again once the next increase in price cap comes in.

    A Local Authority in the South East, has made electric boilers a condition of planning permission for at least 3 projects that I have been involved in, so I don't think it will be very long before this becomes standard.
