Hot-water bottles are very popular in many households. They help with many different types of pain, such as stomachache, back pain, or menstrual pain. However, using a hot-water bottle is not as easy as many people think. If you make, for example, mistakes when filling the bottle, scalds or burns may occur. In addition, the filling quantity and the temperature of the water are crucial for the correct use of the heat source. A hot-water bottle should also be stored properly.
Filling a hot-water bottle correctly sounds child's play at first - but in the following article, we explain what you should pay attention to in order to minimize any risk of injury.

In a step-by-step guide, we explain how you can fill a hot-water bottle safely and correctly. 1.Choosing the right hot-water bottleHot-water bottles are available in many different designs, but their basic principle is quite similar. They usually consist of a thickly lined, flat water bottle, often made of rubber, with some kind of padding or cover on the outside. Some bottles have a thicker cover made of another material, such as PVC or heat-resistant plastic. This allows you to find the hot-water bottle that works best for you. The quality of the hot-water bottle must be good so that it does not burst or become porous.
2.Emptying old waterUnscrew the stopper and pour the old water out of the bottle. If you leave the old water in the bottle, your hot-water bottle may become cold again more quickly. For hygiene reasons, it is also important to change the water regularly and wash out the bottle.
3.Heating the waterIf you want to fill your hot-water bottle with hot tap water, it is often not hot enough. Instead, you can boil water in a kettle. However, you should then let the water cool for a few minutes, as it is still too hot for the hot-water bottle. If the water is too hot, it can burn your skin even though it is inside the hot-water bottle. A suitable water temperature is around 60 degrees Celsius; for children, it is 40 degrees Celsius.
4.Filling the hot-water bottleWhen filling the hot-water bottle with water, be careful not to spill any water. This could cause scalds. Make sure you hold the bottle by the neck. If you hold it by the body, it may lose stability and the water may flow out from the top. You should also fill the hot-water bottle only two-thirds full, as otherwise the bottle could burst or hot water could run over your hands while you are filling it.
5.Removing air from the hot-water bottleAfter filling the hot-water bottle, you can carefully press the remaining air out of the bottle. Press until you see the water rise to the top. Then screw the stopper back onto the hot-water bottle and carefully check whether it is watertight.
Tips for filling a hot-water bottle correctly
Check the hot-water bottle for damage
Before using the hot-water bottle, you should check it for possible damage to prevent the bottle from leaking and protect yourself from scalds. Look for cracks or porous areas.
Avoid boiling water
You should absolutely avoid using boiling water. Even if the hot-water bottle is watertight, prolonged contact with the skin can cause redness or burns. The heat also creates water vapor, which could cause the bottle to burst in the worst case.
Store the hot-water bottle empty
The hot-water bottle should be emptied before it is stored. If water remains in the bottle, the material may be subjected to excessive stress. The stopper should also not be screwed on completely, as otherwise the bottle cannot dry from the inside and additional moisture will form.
Tip: A hot-water bottle is a wonderful aid when you want to do something good for yourself after a tiring day. It generally retains its temperature for several hours, but with a few spoonfuls of salt in the hot water it stays warm even longer.
