  • the hot water tank according to the invention can be adapted to the current energy situation and the amount of hot water available. Due to the variable volume of the tanks, each having a different temperature level, a volume corresponding to the amount of energy available is made available for each temperature level at any time, as a result of which energy can be saved and used economically.
  • the latest findings in heating technology and its individual components, in particular the different possibilities of energy generation and generation can be linked and combined with one another in the sense of an optimization of the energy sources to be used in particular with the inventive hot water tank.
  • the design is such that the material of the tanks is selected such that the weight of the tank is less than the weight of the stored liquid and the liquid surrounding the tank. This automatically adjusts the volume when hot water is supplied to or removed from one of the tanks the same by utilizing the buoyancy of the respective inner tank in an outer tank.
  • the design is preferably such that a valve for connecting adjacent tanks is provided on the bottom surface of the respective inner tank. If the valve body is seated on the bottom surface of the surrounding tank, the valve can be opened automatically if the valve is designed accordingly, so that the amount of liquid in adjacent tanks can be automatically compensated for by overflow.
  • temperature sensors are preferably provided in the tanks.
  • the design is such that the external tank is connected to a cold water reservoir bounded by the container via an overflow opening.
  • the design according to the invention is developed in such a way that a connection line to a heat exchanger or to an energy source, in particular a solar energy system or a solid or liquid boiler, is connected to the water reservoir, and that the heat exchanger or the energy source is connected via lines whose passage cross-section is via a Control device is controllable depending on the temperature of the heated water, can be connected to different tanks in the container.
  • a connection line to a heat exchanger or to an energy source in particular a solar energy system or a solid or liquid boiler
  • the training is preferably such that a float valve is provided in the cold water volume, which controls a flow valve in a supply line to the cold water tank depending on the liquid level in the cold water tank.
  • the design is preferably such that elements of a heating system, in particular heating coils, are arranged in at least one internal tank, whereby a low-temperature heating system and a radio heating system can be implemented in a simple manner.
  • the design is further preferably made such that a heat pump can be connected to a tank of medium temperature levels.
  • FIG. 1 shows a section through a first embodiment of a hot water tank according to the invention
  • Figure 2 shows the hot water tank shown in Figure 1 with a simple hot water control
  • FIG. 3 shows a modified embodiment of the hot water tank according to the invention with the connection of a heating system.
  • Fig. 1 denotes a fixed container, three insulated, telescopic tanks 3 are attached to the cover 2 of this container forming the hot water tank.
  • the tanks can contract or expand in accordance with the addition or delivery of liquid, as will be explained in more detail with reference to the following figures.
  • the inside tanks are each Via valves 5 arranged in the bottom surface 4, while the volume delimiting the outer, telescopic tank is connected via an overflow opening 6 in its upper edge region to a cold water reservoir 7 delimited by the jacket of the container 1.
  • the three telescopic tanks arranged inside the container 1 are shown in their fully retracted position, in which the tanks 3 each have their smallest possible volume.
  • the bottom valves 5 are opened by resting an outer tank on the inner tank, so that a liquid equalization between two adjacent tanks takes place automatically.
  • an extraction line 8 opens into each of the tanks, which leads to consumers (not shown in more detail).
  • Pumps and / or valves 9 are switched on in these extraction lines 8, control lines from a central control device 10 to these pumps or valves 9 being designated 11.
  • the control unit 10 also controls pumps or valves 13 in supply lines 14 via control lines 12, via which heated water from a heat source 15 is conducted into the individual tanks in accordance with the temperature of this heated water.
  • the temperature distribution in the individual tanks is such that the highest temperature prevails in the inner tank and a lower temperature prevails in the outer tanks.
  • heat sensors 16 are arranged in these, which are also connected to the control unit 10 via lines 17.
  • the device in the present case comprises a heat exchanger 25, to which water is supplied from the cold water reservoir 7 of the container via a line 18, which after heating up as a function of the temperature determined with the temperature sensor 19 via the supply lines 14 is one of the Tanks fed becomes.
  • the temperature sensor 19 is also connected to the control unit 10 via a line 20.
  • a solar energy system, a heat pump or a fuel boiler 21 can be used as the energy source for the heat exchanger 25.
  • the liquid level in the cold water reservoir 7 is kept at a constant value via a float valve 22, which float valve is a flow valve. controls a pump 23 in a supply line 24.

  • a corresponding temperature gradient can be set via the control device by means of a programmable temperature difference between adjacent tanks. In connection with the use of a Heinz system, for example, a temperature difference of 15 ° C between individual tanks has proven to be favorable.
  • the inner tanks When using a solar system 26 to supply the heat exchanger 25, the inner tanks in each case expand by appropriate hot water supply on fair weather days, since water taken from the cold water reservoir 7 via the line 18 is heated and fed into the respective inner tank.
