Firefighters ask: "Does Your Hot Water Bottle Need Replacing?" Here’s How to Check

Hot water bottles are a longstanding, low-cost way to stay warm, but they typically have a lifespan of about two years. Do you know how to check when yours will expire?

Here's a quick and easy way to find out: Look for the 'Flower Wheel' or 'Daisy Wheel' on the funnel or neck of your hot water bottle. This will show you the manufacturing date.

How to Read It:

The number in the centre of the wheel indicates the year it was made (e.g., ‘20’ means 2020).

The 12 petals around the wheel represent the months of the year.

The dots in each petal represent the weeks of that month. For example, 3 dots in the fifth petal means it was made in the third week of May.

If your hot water bottle is more than two years old from the manufacturing date, it is at risk of leaking or bursting. For your safety, it's time to replace it!
