Brits are being warned of the telltale signs that indicate their hot water bottle is out of date and could be dangerous.
During winter, many people dust off their hot water bottles and use them as an inexpensive way to keep warm throughout the
However, sleep and mattress experts at have warned that signs such as difficulty retaining heat, softened material, and discolouration could mean that the bottle is no longer safe to use.
The experts are urging people to check the expirary date of their hot water bottles, which should ideally be replaced every two to three years.
After this period of time, their material has deteriorated and continuing to use them could lead to burns and leakages.

Rebecca Swain, mattress expert at said: “Many of us will have dug out our hot water bottles by now to help fight the cold weather.
“While they can be a great way to stay warm it’s important to remember that they need to be replaced every couple of years to use them safely.
“Over time these bottles deteriorate from constantly being filled with warm water. It compromises their structure and as the material gets thinner, it increases the risk of splitting or bursting and causing burns.
“Water bottles should have the year they were manufactured on them so you know when they need replacing but if yours doesn’t then there are some other telltale signs that it could be too old to use.”

Signs your hot water bottle is out of date
Check the date
All water bottles should have a wheel on the neck with a number in the middle to show you what year it was made. For example, if the circle says 22, the hot water bottle was made in 2022.
The outer part of the wheel has 12 segments representing each of the months and these will be filled with dots to indicate which month the bottle was made in.
For example, if six of the segments are filled with dots, it was manufactured in June, the sixth month.
Softened material
Hot water bottles shouldn’t feel soft and flimsy. If yours is it could be a sign that the quality of your bottle has deteriorated and has lost its durability.
Difficulty retaining heat
If you’re finding that your bottle feels as though it doesn’t stay warm for long enough compared to before then this could be another indication that the material has softened.
Discoloured
A discoloured bottle could mean you have had it for too long. It is recommended that hot water bottles are replaced every two to three years and it could be time to get another.
Expansion when filled
A good quality bottle shouldn’t expand or stretch when filled with water. If your bottle is expanding after you have poured water into it it is likely the material inside has deteriorated quite a bit.
