Device for delivering hot water comprising a hot water tank (1) in which a thermostatically controlled heating unit (3) is provided, a syphon (4) for the removal of hot water, the inlet opening of which syphon is situated at a first level (5), a cold water inlet pipe (6) in which a shut-off valve (7) controlled by a control unit (8) is provided, and a level probe (10) at a second level (9) above the highest point of the syphon. After the opening of the shut-off valve in response to a start signal the level probe (10) detects when the rising surface of the water has reached the second level and then delivers a signal to the control unit in order to close the shut-off valve. A second level probe at a third level above the first level but below the second level, provides an 'open' signal to the shut-off valve unless the presettable end setting of a counter, counting the number of generated 'open' signals, has been reached.

Device for delivering hot water

Equipment for supplying a quantity of hot water, for example for preparing hot drinks, provided with a heating unit for bringing the quantity of water to a predetermined temperature, the inlet of which is connected via an intake pipe and via an intake valve to a cold water pipe and the outlet of which is connected to a discharge pipe, means for supplying a further quantity of water which is not brought to the predetermined temperature by the heating unit, which further quantity is dependent on the desired temperature of the total quantity of water to be supplied, temperature-selection means for selecting the desired temperature, which temperature-selection means supply a temperature-selection signal to a control unit, said control unit furthermore receiving a quantity-selection signal from quantity-selection means and supplying control signals to the intake valve and to the heating unit. The control unit functions in such a way that sequentially said quantity of water at said predetermined temperature and said further quantity of water of lower temperature are supplied.
