I remember pre-central heating at my grandparents' house in Sheffield. Had to sleep on my clothes in the winter, or they'd be stiff as a board and icy cold in the morning! Frost on the inside of the windows, that sort of thing. Electric bedpan was a step up from the bedpan filled with hot coal from the coal fire.
No one will be allowed to have coal fires instead of the electric or gas fired heating now - it will have to be wood instead (which doesn't burn as well in an open fire, better in a woodburner of course)
We had a kitchen stove that heated the hot water for the bath - yes to once a week, because it took all week to collect enough to burn to make enough hot water for that bath! My London grandparents had the same system. Central heating was put into our house in the mid 70s - grandparents (either set) never got it.
London grandparents used to get a delivery of coal for the fires, and coke for the boiler. Separate coal bunkers! We had the same at our house until the central heating went in. Can't even get coal now, as far as I know - not the real stuff, anyway. I live in Australia now, in a massive coal-production area - and WE can't get coal either, it all goes to the power stations or abroad to China and India, to their power stations.
I worry for my family in the UK, especially over the electricity bills - especially my Dad. It's an old, cold house he lives in - no double glazing or anything.
I'm rambling a bit - have crossed thought trains onto the rising power bills thread too.
