The instructions for new rubber hot water bottles always say that it should not be filled from the domestic hot water supply because this will cause premature deterioration.
Life's too short to be worried about such as this, but purely as a matter of interest can any scientists out there tell me what chemical is present in water heated in a domestic boiler that is not present in water that has been heated in a kettle or saucepan?
my 3 oldest mates are my fish (yes, i know im sad!) i put 14 chemicals into my 17 gallon tank every month to counteract the chemicals in the tap water, and they still pull a face! every night at around 5 o'clock, if i turn the tap on what looks like milk comes out? so i have to run the tap for 10 minutes to make it drinkable, surley a waste of water. i still have my hot water bottle, the one i used to use to try and ease the exruciating pain from pancreatitus i used to get very often as a reminder of reality.
i too like a cold bedroom, and i dont really see the point of hot water bottles when you can use very safe all night only just warm blankets that take the chill off the WHOLE bed not just where your feet are!
I was very alarmed one cold night to see my wife popping a new one in the microwave. Thought she'd gone barmy until I saw it contained some sort of crystals. Her usual hot water version had failed after many years of use, so she'd bought a replacement and this other thing. She still prefers the hw version though. TC.
