Abstract (en)
The water heating appliance of the invention has a vertical container which may be connected to a central heating boiler (12) and has in its interior a sleeve (27) with closed bottom (28) and open top, a tap water coil (7) being provided between the container wall and the sleeve. Thereby colder water from the boiler (12) is entered through the sleeve bottom (28) and the coil (7) is always in contact with the hottest water, so that the tap water temperature is kept better constant.
