Hot water bottle safety advice

Stay safe using hot water bottles this winter with tips on correct filling, avoiding burns, and checking for damage to keep you warm without risk.

Hot Water Bottle

Hot water bottles are a cozy companion during chilly nights, but it’s crucial to use them correctly to ensure safety.

Risks to consider: Hot water bottles, if misused or old, can crack, leak, or even explode, potentially resulting in severe burns or injuries.

Determining your hot water bottle’s age

  • Always be aware of the age of your hot water bottle. Their typical lifespan is about two years. Beyond this, the risk of damage increases.
  • Unsure about its age? Check the daisy wheel imprinted on its neck or body.
    • The central number indicates the year (e.g., ’22’ for 2022).
    • The 12 segments around this number represent months. The filled segments mark its manufacturing month. For instance, if eight segments have dots, it means the bottle was crafted in August.
An image of a dial on a hot water bottle showcases a center with the number '20' and six segments filled with dots. This implies it was made in June 2020 during its third week.

Safety tips for hot water bottle usage

  • Use hot water, but avoid boiling temperatures.
  • Fill up to three-quarters only to minimize bursting risks.
  • Remove all air above the water level before sealing to prevent injuries due to escaping hot air.
  • Ensure the stopper is tightly secured.
  • Wrap the bottle in a cloth or towel to avoid direct skin contact.
  • Refrain from taking the bottle to bed.
  • Don’t combine the use of a hot water bottle with an electric blanket.
  • Avoid using the bottle as a cushion or sitting on it.
  • Store the bottle without any weight on top.
  • Replace your bottle every two years.
  • Regularly inspect for wear and tear.
  • Babies should never be given hot water bottles, wheat bags, or electric blankets.

Incase of scalds: If someone suffers from a scald due to a hot water bottle:

  • Seek guidance on the NHS website.
  • If the scald covers an area larger than the injured person’s hand or is on sensitive parts like the face, neck, hands, or feet, seek immediate medical attention at A&E.
  • In cases of doubt, consult NHS 111 online.
