Using a hot water bottle safely: the key rules

Temperature, fill level, cover: how to use any hot water bottle safely.

Hot water bottles are among the most common causes of scalds at home. Follow a few rules and it won't happen.

With rubber hot water bottles

• No boiling water, let it cool down a little first.
• Only fill it about two-thirds full and squeeze out the air.
• Screw the stopper on tightly and briefly check it upside down.
• Never directly on your skin, always with a cover.
• Don't sit or lie on it.

With the Vaermflasche

• The top levels get really hot: use a cover or a layer of fabric.
• Only charge it with the cable provided, then unplug it.
• Close the cap on the port after charging.
• Children only under supervision; if in doubt, check with a doctor.

The Vaermflasche

Never boil water again. Plug in, 3–6 minutes, warm. Up to 70 °C, no battery, 30 nights to try.
