After a news report yesterday, I decided to check my hot water bottle as the average 'lifespan' is around 2 years...I really wasn't aware that the number in the centre of the flower is the year the bottle was manufactured, so a bottle with a 16 was made in 2016.
The twelve petals of the flower represent the months of the year. The number of segments filled with dots shows which month it was made.
The report featured stories of people who had been horribly burnt after the bottle burst...off to buy a couple of new ones today I think.

Retiring and living frugally in money from downsizing after years of stress


My HWB says it dates from April 2010. I’m astonished, as I am sure it’s been replaced in the past five years or so. Maybe it had been hanging around in the small chemist where I bought it for the previous eight years.
