The device 1 for storing and delivering domestic hot water, to a kitchen sink for example, contains water heated by waste heat from a compressor 15. The compressor is part of another appliance 16 nearby such as a refrigerator, freezer or air conditioning unit. The water is kept hot by recirculation through a heat exchanger 2 that is an integral part of the compressor. The storage device may have a variable volume 11 so that when a quantity of hot water is used it is not diluted by cold water entering the device. Cold water is heated before entering the storage device by passing it through the heat exchanger. When all the stored hot water is used up a smooth switch over to another source of hot water may be achieved. |
