When should I replace my hot water bottle?

When should I replace my hot water bottle?

At least every 2 years from the date of purchase.

Hot water bottles don't have a fixed "expiry date" but they do have limited lifespan because over time, the rubber can degrade, especially with regular use and the repeated exposure to heat, air, and pressure during filling, use and storage.

Whilst The Hot Water Bottle Company recommends that you replace your hot water bottle at least every 2 years from the date of purchase to ensure you are always using a hot water bottle that is safe and fit for purpose, you should replace your hot water bottle more often if you use it regularly or if:

  • There are visible signs of wear, for example, cracks, punctures, or leaks
  • The hot water bottle has lost its flexibility and has become stiff or brittle.
  • The hot water bottle has become discoloured, either it has faded or become darker in areas. 

Finally, ALWAYS follow the instructions for filling, use and care that come with your hot water bottle, such as not overfilling, not using boiling water, expelling air, not using your hot water bottle as a cushion or storing it incorrectly as misuse can shorten the lifespan and result in accidents.
