Product Information

Although only some body parts are directly heated, the warmth from the bottle(s) is distributed throughout the body by skin blood flow.

Because I don’t have the time nor the budget to send hot water bottles to everyone, I have written this article. Water intoxication, or overhydration, can occur when you drink an excessive amount of water in a short period of time. They can also be a very good improvement to a hot water tank, for example for residential solar thermal applications. This is achieved by flipping the bag every 5 seconds or so until it’s warm enough for the person using it.In modern households, hot water can be sourced from an electric kettle, a pot on the cooking stove, or the hot water tap. The great advantage of heating the bottle in this way is that the same water can be used over and over again.

the tap water from a modern domestic hot water system is regulated to a temperature not high enough to cause scalding and in my experience not hot enough to cause frozen windscreens to shatter, the plastic fizzy pop bottle is of course free! I haven’t checked it with a thermometer, but an educated guess would be around 110 F, no more than 120 F.In the eighteenth century, wealthy women kept specially bred “hand dogs” – toy poodles – around to keep their lap and hands warm.

In the context of the energy crisis that we are fearing for this winter, I actually think that somewhat like you, can help a great deal of people in this situation. In Japan, where despite cold winters central heating is even today something of a rarity, yutanpo like these are considered more a necessity than the luxury we might think in the west.

For example, it was common for the whole family to sleep together in the same bed – and this included potential visitors. Another way to investigate the energy savings potential of the hot water bottle is to calculate how much energy it takes to prepare one and compare that to the energy use of a central heating system.
