ABSTRACT:
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.
