Just bought a new hot water bottle, and it says on it not to use boiling water. Why?
I have been using boiling water in hot water bottles all my life, and I cannot see why boiling water should not be used.
On a serious note, I think it has something to do with the fact that water at boiling point might perish the rubber, thus causing leaks.
On a lighter note, we no longer live in the 1950s, but if you feel you really must use a hot water bottle, then I suggest filling it with cold water and microwaving on medium high for two mins.
get yourself a cherry stone hotty instead. heat in the microwave for 3 minutes, lasts for ages and you don't get that horrid rubbery smell. much easier.
This has always been the case, for years it has said not boiling water - my mother used to say it was because of the rubber perishing (in those long-ago pre-litiginous days....)
Now I find that one of those hay pillows works just as well, as is said, just pop it in the microwave.
oh i love my hot water bottle,
ive got it toasting my feet as we speak,
i always fill mine with boiling water and have it in a soft fleecy cover.. very cosy ;o)
