The Tin Bath And The Immersion Heater
"Who left the immersion on?"
Hot water you had to plan an hour ahead, and a switch in the airing cupboard that started family arguments.
The immersion heater was expensive to run and every household had one person who policed it. Leaving it on was a genuine domestic crime.
Plenty of homes still had a tin bath in front of the fire well into the seventies, refilled from the kettle and shared in order of seniority.
Cost back then
A few pence an hour to run
Goes for now
Tin baths sell as garden planters for £40+
