- the device according to the invention can be surrounded by a heat insulation jacket in order to avoid unnecessary heat losses to the environment.
- the device according to the invention is formed in two halves, the cutting plane between the halves or parts is best placed in the plane of the connecting lines for manufacturing reasons, so that the connecting lines can each be designed as half pipes. In principle, it is irrelevant what type of cross-section the connecting lines have. Usual round cross-sections can be used equally, such as square or oval cross-sections or other cross-sections.
- the device comprises a housing, which preferably surrounds the device in a heat and / or sound-sealing manner at least in regions, in order to dampen working noises from pumps or valves or flow noises.
- the design according to the invention also makes it possible to integrate the control technology into the device, so that structural advantages and installation advantages also result here, since hardly separate parts, temperature sensors etc. are required, but can be integrated into the device according to the invention.
- the device according to the invention makes it possible to implement different types of lines and types of control without causing major problems. installation errors could occur, since all lines, line branches, etc. are already fixed.

- a flow from the heat generation station in particular a central heating system, a return to the heat generation station, a hot water or cold water inlet and a hot water outlet for heated hot water are necessary.
- the radiator flow and the radiator return for supplying at least one radiator of a residential unit with the heating medium could also be accommodated outside the device according to the invention.
- a process water return for cold water could also be accommodated outside the device according to the invention. It is of course preferred if the latter three fluid paths are also integrated into the device according to the invention, since this minimizes the assembly effort, which in the case of such known devices means the major part of the construction costs.
- a particularly advantageous embodiment results if a valve device is arranged between the flow, the radiator flow and the return, which regulates the flow temperature of the heating medium or fluid for the radiator (s) of a residential unit to a predeterminable temperature.
- a bypass line between the radiator flow and the return or radiator return is required for this.

- the device according to the invention can also have eight or nine connections instead of seven.
- the lines within the device according to the invention can be molded in such a way that the heat exchanger is connected in series with the radiator or radiators, i.e. the heating medium from the heat generation station first flows through the heat exchanger before it is supplied to any heating surfaces for space heating purposes.
- This has the advantage that the heat exchanger is always adequately supplied with heating medium, so that domestic water is always available at a higher temperature and when a hot tap is opened there are no waiting times until heated water emerges.
- the heated process water can be very hot in this configuration, it is also advantageous to provide a temperature sensor at the process water outlet of the heat exchanger that switches a valve that is provided in a bypass that can short-circuit the line loop through the heat exchanger, for example overheated Used water to be able to add cold water so that scalding cannot occur, especially if the flow temperature of the heating medium from the central heat generation station, hereinafter referred to as the boiler, is relatively high, at around 70 ° C and above.

- a bypass is also provided here, via which the heating medium from the boiler return can be added to the heating medium from the boiler flow via the valve in order to be able to supply the heating surfaces with an optimized temperature. This is particularly beneficial when using large quantities of hot domestic water are required so that the heating medium which is supplied to the heating surfaces would be too cold to maintain a predetermined room temperature.
- the boiler flow temperature would have to be set relatively high and by adding used heating medium from the boiler return to a lower temperature in front of the heat exchanger, so that an excessive decrease in the temperature of the heating medium behind the heat exchanger and in front of the heating surfaces could be responded to by the fact that the valve used throttles or even completely prevents the addition of used heating medium from the boiler return.
- the heat exchange device is connected in parallel to the heating surface (s) or radiators.
- heating medium can be supplied via a distributor valve, which is arranged between the boiler flow, the heating surfaces and the flow of the heat exchanger, whereby a temperature sensor can be arranged on the process water drain for the heated process water in order to decrease a control value , which is fed to the distributor valve in order to keep the temperature of the hot domestic water that is discharged through the regulated supply of the heating medium.
- the scalding protection described above can also be used instead by adding cold water via a bypass.
- a changeover switch can be provided which, for example, influences the conveying speed of one or more pumps inside or outside the device in order to be able to supply more or less heating medium from the boiler flow.
- control valves are relatively expensive and not infrequently still susceptible, a combination of cheap pumps can be used instead of changeover valves, distributor valves or the like.
- a pump can be arranged, which supplies the heating medium from the boiler flow to the heating surfaces.
- a throttle device in particular a gravity brake, is provided between the pump and the heating surfaces in order to prevent water from flowing in the reverse direction when the said pump is out of operation.
- Such a throttle can consist, for example, of a one-way valve or of a helical line which ensures a pressure drop along a shorter Leiwngs section, so that although heating medium can flow to the heating surfaces when the pump is in operation, the heating medium in the in the opposite direction must overcome a line resistance that is too high for a significant reverse current to flow against the direction of delivery of the pump.
- a pump for the heating medium can be provided in front of or behind the heat exchange device, for example a heat exchanger or a heat pump, it being accepted in each case that a low leakage current of heating medium can occur through the pumps.
- the delivery rate of the pump for the heat exchange device can also be specified by a heat sensor at the outlet for the heated service water.
- a thermally controlled switch in the heat exchanger can additionally provide a switching criterion or control criterion for the pump on the heat exchange device.
- the leakage amount of heating medium that passes through the pump on the heat exchanger is also advantageous, since this permanently occurring leakage amount ensures that the heat exchange device remains warm in warm weather periods, for example in summer, without additional control effort, so that there is no need to wait until warm service water is available Available.
- a heat meter is also provided in the device according to the invention, which counts, for example, the amount of heat that flows into the device according to the invention via the boiler flow or is supplied to the living unit.

- the device according to the invention which is referred to below as a heat storage cabinet, has been generally identified by reference number 10.
- the heat storage cabinet 10 is formed in one piece, two halves 12a and 12b, in which lines 30a, 30b shown by way of example are each provided in half, being created.
- the two halves 12a, 12b are assembled via respective seals 34 in order to provide the required tight conduction paths which are required in order to be able to perform the desired functions of the heat storage cabinet 10 according to the invention.
- receiving spaces 32 are created, which are provided, for example, for sealing valves 28a, 28b, 28c, counting devices, such as heat meters 36 or water meters 26, pumps 14 or the like, so that they flow onto the flow paths 30a, 30b of the heat storage cabinet 10 according to the invention can be accessed in the desired manner.
- the one-piece design of the heat storage cabinet 10 enables the housing geometries of, for example, pumps 14, heat meter 36 or water meter 26 to be integrated directly into the halves 12a and 12b by casting or simple reworking of the mold. It is also possible for the formation of a pump housing to interrupt the pump flow path in the halves 12a and 12b through a recess. A comparatively easy-to-machine insert, for example made of plastic, is pressed into this recess, which together with the halves 12a and 12b now forms a pump housing into which a pump head consisting of a pump impeller and pump motor is merely inserted. In view of the large number of necessary housings with adapted inner geometries for pumps, valves, counters, sensors and the like, this results in considerable space savings and a cost reduction.
- Lines 24 as signal line sections or control line sections are also provided, for example in order to be able to regulate the pump output of the pump 14 via a pump controller 15 or to be able to change the position of the valves 28a to c.

- a cold water discharge 122f is arranged in front of the heat exchanger in the process water circuit in order to discharge cold water, in particular as process water for the residential unit assigned to the heat storage cabinet according to this embodiment.
- a bypass with a control valve device 168 is arranged between the cold water discharge 122f and the discharge for heated process water 122e.
- a temperature sensor 170 on the outlet 122e for heated service water sends a signal to the control valve 168, according to which a certain amount of water is supplied to the warmed service water is added so that excessively heated service water is not passed on via the discharge, which could otherwise lead to scalding.
- the heating medium supplied to the radiators 190 via the radiator flow 122a is returned via the radiator return 122b to this embodiment of a heat storage cabinet according to the invention and can be added to the heating medium at the boiler flow 122d via the valve 158, or can be via the boiler return 122c from the invention trained heat storage cabinet are transported out.
- a preferred embodiment shown in FIG. 5 according to the invention has corresponding connections, as it has the embodiment according to FIG. 4.
- the three-way valve 352 is only controlled as a function of a temperature of the heated service water measured by a temperature sensor 351. If the temperature of the hot water to be heated drops below a predetermined value, the distributor valve or three-way valve 352 is controlled in such a way that additional or more heating medium is supplied to the heat exchanger 316 in order to raise the temperature of the hot water to be heated. The same applies in the event that the domestic water to be heated takes on an excessive temperature.
- the pump device 356 is here only controlled as a function of the changeover switch 360, which is able to carry out a control as a function of, for example, the season's environmental temperature.
- the heating medium used by the heat exchanger 316 or 116 is fed back into the boiler return 322c or 122c via a connecting line 366 or 166.
- the heat exchanger 516 in the embodiment according to FIG. 6 is not arranged parallel to the radiators 190, 390, but is connected in series with the radiators 519 so that it without requiring separate control, the flow of heating medium is permanent, insofar as an electrical switchover valve 552 connected via its electrical circuit 554 either includes the radiators 590 in the circuit or else excludes them from the circuit.
- a pump device 556 allows a leakage amount of heating medium to pass through, so that even in a warm weather period when the radiators 590 are not subjected to flow, the heat exchanger 516 is always supplied with at least a small amount of heating medium via the boiler flow 522d, so that Service water is kept warm in the heat exchanger 516, so that there are no waiting times when hot service water is withdrawn.
- a temperature sensor 564 in the heat exchanger 516 is connected on the one hand to the changeover valve 552 in order to be able to restrict the supply of heating medium to the radiators 590 in the event of a larger hot water requirement, in order to provide the heat exchanger with more power.
- the temperature sensor 564 is also connected to the pump device 556 in order to activate it, for example, in a good weather period, when the radiators 590 do not have to provide heating power, when the temperature in the heat exchanger falls below a predetermined minimum value.
- cold water can be added to the hot water heated by the heat exchanger via a valve 568, depending on the temperature of the heated hot water sensed by a temperature sensor 570, in order to provide scalding protection.
- the valve 558 is controlled as a function of the temperature of the heating medium felt by a temperature sensor 550, with more or less or no used heating medium being added from the boiler return 522c via the bypass 562 to the heating medium at the boiler supply 522d, depending on the temperature sensed.
- the heat exchanger 1416 is again integrated into the heating circuit parallel to the radiators 1490.
- pumps 1456, 1482 are used instead of control valves, which are operated faster, slower or not at all, depending on the sensed temperature of the heated service water or the heating medium to be supplied to the radiators 1490.
- a gravity brake 1480 prevents the flow of the heating circuit from reversing.
- the pump 1482 must allow a leakage current for the heating medium, so that the heat exchanger is always flowed through by heating medium, so that when hot domestic water is requested in good weather periods, when .other heating power is not required, does not occur.
- the pump 1482 can also be operated faster or slower depending on the temperature sensor 1464 in the heat exchanger 1416, so that heating medium can also be supplied in order to heat the heat exchanger again, regardless of the leakage amount of heating medium when the temperature in the heat exchanger drops.
- a control can also be carried out on valve 1458 in order, as in the embodiments explained above, to regulate or reduce the addition of cooled heating medium from boiler return 1422c if an undesired change occurs or that Temperature in the heat exchanger falls below a predetermined minimum value.
- different minimum temperatures can be used as a starting condition for the control of a particular device. For example, when the temperature in the heat exchanger falls below a certain level, the delivery capacity of the pump 1482 can first be increased. If a further temperature mark is undershot, a corresponding regulation can be carried out on the valve 1458 or on the pump 1456. If the temperature in the heat exchanger 1416 falls below a further minimum temperature, additional control on the pump 1456 or the Valve 1458 can be made. Of course, all regulations can be carried out overlapping or intermittent.
- the heat exchanger has also been arranged parallel to the space heaters 1590.
- the process water preparation circuit corresponds in principle to the point shown approximately in FIG. 6.
- the connection of the heat exchanger 1516 to the boiler corresponds in principle to that shown in FIG. 7, but the pump 1582 is controlled exclusively as a function of the temperature of the heat exchanger 1516 felt by the temperature sensing device 1564.
- a gravity brake 1580 which is also provided here, prevents used heating medium from flowing back when the pump 1582 which allows a leakage quantity is out of operation.
- the temperature sensor 1564 can also influence the pump 1556 assigned to the radiators 1590 if e.g. the temperature in the heat exchanger has been lowered too much, and can restrict the supply of the heating medium to the radiators 1590 or temporarily completely stop it until the temperature in the heat exchanger has returned to a predefinable acceptance range.
- the heat exchanger 1516 can also be conducted by heat conduction within the heat storage cabinet according to the invention, i.e. be sufficiently heated by a sufficient thermal conductivity of the material.
- the pump 1556 when the pump 1556 is out of operation, only the pump 1582 works.
- the start-up can then be carried out by the temperature sensor 1564, as has already been indicated above.
- the valve 1558 is then in the position A - B, so that the radiators 1590 are excluded from the circuit.
- a bypass 1562 (1462 in FIG. 7 etc.) can be used to produce a quantity of used heating medium of up to 20% at a temperature of 40 ° C are added to regulate the temperature of the heating medium at the boiler flow 1522d from 70 ° C to 50 ° C at the heater flow 1522a.
- the heat storage cabinet according to the invention can be designed in a wide variety of ways, but it can always be formed in one piece in the smallest space and is therefore easy to assemble and easy and inexpensive to produce.
- the heat storage cabinet according to the invention contains the entire control and regulating technology and electronics internally, possibly except for at least one room temperature sensor (not shown) and possibly an outside temperature sensor.
