Abstract: A hot water heater comprises a hot water tank, a supply pipe to be connected to the public water mains and a discharge pipe to be connected to a tap. The hot water tank has a circumferential wall which encloses the interior of the tank and which is provided with a heating element disposed inside the hot water tank and with a temperature control device. The circumferential wall of the tank comprises a part which is bellows-shaped so as to be deformable under pressure, thus enabling the tank to expand and contract. The bellows-shaped part of the tank wall is surrounded by a gas chamber containing a gas under pressure, which is capable of balancing the expansion of the tank. The invention further relates to a method for supplying hot water.

Abstract: A vessel, preferably a pressure vessel, for containing water of a high temperature in an inner space thereof, which vessel comprises at least one passage. A first hose part, around which a first coupling part provided with a clamping surface extends, and a second coupling part formed around said passage, which is provided with a bearing surface, connect to the passage in the vessel. A second hose part extends from said passage into the inner space of the vessel. The first and the second coupling part are interconnected and the first and the second hose part are provided with flanged ends, which are clamped between the bearing surface and the clamping surface in the coupled condition of the two coupling parts, with the first and the second hose part forming a substantially continuous hose.

Abstract: A hand pump for fixing to a working surface comprises a pump housing and an outlet that extends substantially laterally with respect to the pump housing in order to extend above a receptacle. The pump is operable by substantially straight-lined operational movement of the outlet along the pump housing. The outlet and the pump housing are coupled by means of a guide, in particular comprising guiding means in the pump housing, against tilting of the outlet with respect to the pump housing.

Abstract: A water tap is disclosed, which comprises an operating element for operating the tap, a sensor for detection of the touch of at least a portion of the tap by an object and generation of a detection signal and signalling means for generation of a warning signal based on the detection signal. The sensor and the signalling means are configured to generate a warning signal at a touch of at least a portion of the tap. A hot water system comprising the water tap is also disclosed.

Abstract: A device for dispensing water includes a water tank for keeping water at a tank temperature higher than the desired temperature of the water to be dispensed. A tank inlet is connected to a source of water. device includes a mixing device with a first water supply, a second water supply and a water discharge connected to a dispensing point. The first water supply is connected to a hot water pipe originating from a central hot water source arranged at a distance, and the second water supply is connected to a tank outlet. The mixing device includes a control device which is designed to mix water from the first and second water supply in such a manner that the water to be dispensed substantially has a desired temperature.

Abstract: A conduit structure provided with a rotation coupling comprises a first hose part (1) with a first coupling part (4) at an end thereof, and furthermore a second coupling part (5) at an end of a further part (6, 15; 2, 4, 19). The first coupling part can be inserted into the second coupling part and the coupling parts are provided with a separate sealing element (9) as well as with locking means (17, 18), such that the first and the second coupling part are rotatably but non-slidably coupled. The first hose part (1) extends through and some distance beyond the first coupling part (4) and in the coupled condition the sealing element (9) seals the space between the portion of the first hose part that extends beyond the first coupling part and the second coupling part (5).
