At Hot Water Bottle Shop, we do not only care about stylish and effective warming products but also about the safety of our customers. As a result, we have produced a short video (which appears on Youtube.com) to demonstrate best practice when it comes to filling a hot water bottle safely. The video guides you in nine easy-to-follow steps:

  1. Check that there are no obvious signs of damage. Cracks and tears can be very dangerous when pouring hot water in.
  2. Once you are happy that the hot water bottle is safe to use, unscrew the stopper and pour out any water left in inside.
  3. Run the hot water tap and wait for the tempature to heat up. You can use any tap in the house, even a bath tap. But remember, never attempt to use boiling water!
  4. Once hot water is coming out, temporarily turn off the tap and place the hot water bottle underneath it.
  5. Turn the tap back on and fill the hot water bottle until it is filled to about 75% capacity. When comfortable, turn the tap off again and carefully remove the bottle from underneath.
  6. Slowly squeeze the remaining air out of the hot water bottle so that the water level rises to just below the top.
  7. Now screw back on the stopper making sure it's tight.
  8. Finally use a towel or dish cloth to dry the hot water bottle and the stopper.
  9. Your hot water bottle is now ready to use! To be extra safe wrap the hot water bottle in a towel during use.

In addition to what is mentioned above and in the video we have the following additional words of wisdom focusing on safety and hot water bottle longevity:

  • Purchase the right hot water bottle for your needs. These days hot water bottles come in all shapes and sizes, and are made from a variety of different materials. For general warmth, a large, traditional bottle might be called for. If relief of sore muscles is the primary objective, a flexible bean or gel-filled bag might be a better option.
  • Take the time to inspect your hot water bottle before use. Make sure that the hot water bottle compliant with the relevant British Safety Standards (i.e. BS 1970:2006 or BS 1970:2012). To be certain you should be able to find a daisy like symbol on its surface. Look for cracks, fading, or small holes that could indicate a compromised product. Many hot water bottles may show both a production date and/or an expiry date. Replace older or worn bottles to avoid accidents.
  • Avoid direct contact between a hot hot water bottle and skin. The correct use is to wrap a cloth around it or place it in a hot water bottle holder. The extra material prevents scalding and also acts as further insulation to keep the bag warmer for longer. They should also not be leaned against or placed anywhere that results in direct pressure being placed on the bag.
  • To warm a bed or sleeping bag, place the hot water bottle (or two) under the covers for at least 15 minutes before crawling in to sleep. It’s not safe to keep the hot water bottle in bed while sleeping because of the risk of rolling over onto it and causing it to explode from excess pressure. Never sit or lie on a hot water bottle!
  • Children and babies should never be left alone with a hot water bottle, and bottles should not be placed directly on a child’s skin. For use warming a child’s bed, remove the hot water bottle before the child enters the bed to avoid unintentional burns or accidents. Always check the temperature of a hot water bottle to be used with children. Their skin is more sensitive than the skin of an adult and a lower temperature can be more appropriate.
  • After each use, it’s important to empty the hot water bottle and hang upside down to dry. Only once the inside is completely dry should it be folded and stored in a dark, dry location. Exposure to excess sunlight can result in cracks, while storing a wet hot water bottle can result in the growth of mould inside the bottle.
  • Hot water bottles have been used and enjoyed for centuries. Taking the time to use one correctly can result in a better experience and a longer shelf life for your hot water bottle.
