2. Water heater according to claim 1, thereby with double jacket. In addition to the hot water, the system indicates that the heating water tank (11) is a stand-by 1 and the device 2 for space heating is an egg-standing container and that the hot water tank (10) has a separate heating water tank 3, a boiler 4, an in Upper section of the heating water tank is arranged. 15 heat pump 5 and a heat recovery device

3. Water heater according to claim 2, characterized GE- 6, which, connected via a pipeline network, indicates that a further heating device (12) is provided. To pump the heating liquid, several pumps are provided, which are provided in the outside of the heating water tank (11) 7. The control of the heating liquid flow is arranged part of the domestic hot water tank (10) is arranged. there are a number of three-way valves 8 provided by

4. Water heater according to claim 3, characterized by a control device for the heating, not shown, that the further heating device (12) controls a heating system, so that the element of the water heater. 1 heating fluids supplied from the various heat sources

5. A water heater according to claim 1, whereby the liquid has essentially the same temperature. A we-indicates that the paired inlet and essential prerequisite for this is that the three-way valves 8 outlet ports in the heating water reservoir (11) arranged 25 close properly in both flow directions. Since these are that the inlet and outlet ports (21, 22, 23, 24, 25, three-way valves 8 with shorter switching cycles in this regard 27, 28, 29) are very susceptible to faults at different levels in the heating water supply, increased maintenance is required to lead to (11) earlier, in order to calculate in the heating water storage (11), if economic operation ensures that the heat source will generate dependent temperatures. that should.

6. Water heater according to claim 5, characterized thereby. It was also proposed to provide two heating zones on the tub that at least a part of the inlet and outlet water heaters should be provided, in which the double jacket on the nozzle is provided with a bell (26). Domestic hot water tank divided. This solution aims

7. A water heater according to claim 6, characterized in that a small amount of hot water indicates in a relatively short time that at least part of the bells (26) are available, while the remaining amount of water projects into another inlet or outlet connection, 35 over a longer period, e.g. during the night it is heated end at a distance from the bottom of the bell (26). To control the flow of heating fluid are arranged to form a gap for the overflow. three-way valves are also required here.

8. A water heater according to claim 7, thereby the aim of the invention is to characterize a water heater that the end of the inside of the bell (26), in which the service water is continuously cut off obliquely by means of its own nozzle. 40 ner heating liquid is heated.

9. Water heater according to claim 8, characterized This object is achieved according to the invention with the features in through an inlet and outlet nozzle (21, 22) for a characterizing part of claim 1. Space heating device (15), an inlet and outlet connection. In one exemplary embodiment of the invention, the connections (27, 28) for a boiler (16) and an inlet and outlet connection assigned in pairs in this way are connected and outlet connections (25, 29). for a heat pump (17), where 45 arranges that the inlet and outlet ports differ from the outlet ports (29) for the heat pump (17) to a level in the heating water tank.

on the inlet connector (21) for the space heating device (15) The advantage that can be achieved thereby is that the bell (26) protrudes into the provided connector (25) and the heating water tank reaches different temperatures.
