Doctor Warns: Check Your Hot Water Bottles to Avoid Burns

As cold weather grips the UK, many people are turning to hot water bottles for warmth. While these items are an effective and affordable solution, caution is advised. In 2024, nearly 1,000 people were admitted to burn units in England and Wales due to accidents involving hot water bottles, according to the Royal Society for the Prevention of Accidents (RoSPA).

Understanding the Risks of Hot Water Bottles

Dr. Richard Anderson, head of learning and development at High Speed Training, emphasizes the need for awareness regarding the potential hazards of hot water bottles. “Hot water bottles are a fantastic way to beat the chill, and with energy costs remaining a concern, they are more popular than ever,” he stated. “However, like any household item that utilises high heat, they aren’t without risk.”

One of the key safety tips is to check the age of your hot water bottle. It is recommended to replace them every two years. The rubber material can deteriorate over time, increasing the likelihood of splitting or leaking. To determine the age of your bottle, look for a flower-shaped symbol, referred to as the “daisy wheel,” which is embossed on the neck or body of the bottle.

This symbol contains a number in the centre indicating the year of manufacture, while the twelve surrounding segments represent the months. Dots within the segments indicate the specific month of production. For instance, a bottle marked with a 25 in the middle and dots in the first six segments would have been made in June 2025.

Safe Usage and Maintenance Tips

When filling a hot water bottle, Dr. Anderson advises checking for any noticeable damage or wear. Avoid using boiling water, as this can damage the internal seams. It is best to allow the water to cool slightly before filling. Furthermore, only fill the bottle about two-thirds full, expelling any remaining air before securely tightening the stopper.

To prevent burns, always use some form of cover on a hot water bottle and avoid sitting or lying on it, as this can increase the risk of failure. When not in use, it is essential to drain the bottle and store it with the stopper removed in a cool, dry place, such as a cupboard.

As the winter months continue, following these guidelines can help ensure that hot water bottles remain a safe source of comfort during the colder weather.
