With the cold weather continuing across the UK, many people are turning to hot water bottles to stay warm during the day and at night. They’re cheap, easy to use and help cut heating costs — but they do need to be used carefully.
Figures show that in 2024, almost 1,000 people in England and Wales were treated in hospital for burns caused by hot water bottles. Safety experts say most of these injuries can be avoided with a few simple checks.
Check how old your hot water bottle is
Hot water bottles don’t last forever. Experts recommend replacing them every two years because the rubber can weaken over time and may split or leak.
You can check the age by looking for a small flower-shaped mark, known as a “daisy wheel”, on the bottle. The number in the centre shows the year it was made, while the dots around the edge show the month.
If your bottle is older than two years, it’s safer to replace it.
Filling and using your bottle safely
Before filling your hot water bottle, always check it for cracks, thinning rubber or leaks. Do not use boiling water, as this can damage the seams — let the water cool slightly first.
Only fill the bottle about two-thirds full. Gently squeeze out the air before tightening the stopper securely.
Always use a cover to prevent burns to the skin, and never sit or lie on a hot water bottle, as this puts pressure on it and increases the risk of it bursting.
When you’re not using it, empty the bottle and store it in a cool, dry place with the stopper removed.
Taking a few minutes to check and use your hot water bottle properly can help keep you warm — and safe — through the colder months.
