ACCC launches hot water bottle blitz". The Sydney Morning Herald. Fairfax Media. AAP. 21 July 2009. Archived from the original on 24 July 2015. People should ensure that they use hot, but not boiling, water when filling the hot water bottle up. Placing the bottle in a covering or wrapping it in a towel can help maintain its heat and minimize injuries such as burns. Jha, Alok (5 July 2006). "Heat 'relieves internal pain' ". The Guardian. Archived from the original on 25 September 2014. Hot water bottles provide thermal comfort with all the windows open. Illustration by Marie Verdeil.

Some newer products function like the older bottles, but use a polymer gel or wax in a heating pad. The pads can be heated in a microwave oven, and they are marketed as safer than liquid-filled bottles or electrically heated devices. Some newer bottles now use a silicone-based material instead of rubber, which resists very hot water better, and does not deteriorate as much as rubber. Although the stopper size in Ireland and the UK has been largely standard for many decades, some newer bottles use a wider mouth which is easier to fill (and a larger stopper to fit it). Unsurprisingly, there’s little – or actually no – academic research into the energy savings potential of hot water bottles. Instead, in recent years scientists have investigated more sophisticated personal heating devices such as electrically heated desks and seats, radiant heat bulbs, or battery-powered heat pillows. 5 6 7Oil lamps help. I find that in a well insulated space, a single oil lamp provides light and quite a bit of heat. Eskimos know that a single candle will heat up an igloo very nicely. The United Kingdom defined British Standards for hot-water bottles to regulate their manufacture and sale as well as to ensure their compliance with all safety standards. The British Standards BS 1970 and BS 1970:2012 (updated version) define, for instance, the bottles’ filling characteristics, safety instructions, allowed materials and components as well as testing methods such as tensile tests for PVC bottles.

A hot water bottle is a sealable container filled with hot water, often enclosed in a textile cover, which is directly placed against a part of the body for thermal comfort. The hot water bottle is still a common household item in some places – such as the UK and Japan – but it is largely forgotten or disregarded in most of the industrialised world. If people know of it, they usually associate it with pain relief rather than thermal comfort, or they consider its use an outdated practice for the poor and the elderly.Reading your article about water bottles, a possible improvement occured to me. Instead of using water, one could use a phase change material (PCM) instead. These store thermal energy as the lattent heat of fusion of the phase change from liquid to solid. Examples of these are the sodium acetate hydrate used in hand warmers, paraffin (wax) or even water/ice for cooling needs. A lot of these materials have energy densities that are seriously competitive (or even exceed) the energy release by a water bottle that is cooling down. They however have one major advantage: since most of the energy is released during the phase change, these materials will release heat at a constant temperature (melting temperature). Water releases lots of energy at first (at less safe temperatures) but the rate decreases exponentially as the temperature decreases (it’s literally an exponential decay function). This means that PCMs could provide a significant improvement to water bottles, by releasing energy at a more consistent, safer and more useful temperature.
