<p>Hot-water storage tank, in the cylindrical storage space 1 of which is arranged a coiled tube 6 which carries heating water and the forward run of which opens out in the bottom region of the storage tank and the return run of which extends from the top side of the storage space 1. The coiled tube 6, starting from a double bottom 2 carrying heating water, passes through the storage space 1 over the height of the latter. A thermostat 17 is assigned to the upper region of the storage space and monitors the temperature of the service water to be tapped, and there is also a further thermostat 18 assigned to the lower region of the storage space 1. This thermostat 18 is connected to a timer, so that additional heating of the storage tank occurs only when heating controlled by the upper thermostat 18 has not occurred within a predeterminable timespan. <IMAGE></p> |
