Description

[0001] The present invention relates to a kit for a building heating system. Furthermore, the present invention relates to a method for installing a building heating system.

[0002] Heating systems for buildings are known from the prior art. These comprise a heat generator for heating a heating medium, supply lines in which the heating medium is transported from the heat generator to a consumer, for example a radiator, a circulation pump for driving the heating medium in the supply lines and return lines in which the heating medium can be transported back to the heat generator.

[0003] Installing such a heating system with the aforementioned components within a building is time-consuming and sometimes prone to errors. In particular, replacing an existing heat generator in an interior space, such as a boiler room, with a heat pump is labor-intensive, thus increasing the labor costs for such a replacement.

[0004] It is therefore an object of the present invention to provide a kit for a building heating system that enables simple, quick, and error-free installation of the heating system. Furthermore, the present invention aims to provide a correspondingly advantageous method for installing a building heating system.

[0005] This problem is solved by the features specified in claims 1 and 7. Advantageous embodiments of the invention are the subject of the dependent claims.

[0006] The inventive building heating system kit comprises at least two modules. The first module has a planar first support structure. Here, as elsewhere, a planar support structure is preferably understood to be a support structure that extends or covers essentially a surface. A first functional unit for operating the heating system is attached to the first support structure. The first functional unit is a heat generator. The heat generator can be of any type, although a heat pump is preferred. Furthermore, the first module has a first supply line connected to a heating medium outlet of the heat generator. This supply line is attached to the first support structure, resulting in a fixed first outlet end.Furthermore, the first module has a first return line connected to a heating medium inlet of the heat generator, which is attached to the first support structure, thus creating a fixed first inlet end of the first return line. In principle, the first module can also include two or more first supply and / or return lines, which are attached to the first support structure accordingly.

[0007] The second module of the kit is designed separately from the first module and also features a flat support structure, namely a second support structure. A second functional unit for operating the heating system is attached to this second support structure. This second functional unit could be, for example, a circulation pump or an electrical distribution box. Furthermore, the second module has a second supply line, which is attached to the second support structure, creating a fixed second inlet end. Additionally, a second return line is provided, which is attached to the second support structure, creating a fixed second outlet end.In principle, the second module can also include two or more second supply and / or return lines, which are attached to the second support structure in a corresponding manner.

[0008] Thanks to the division of the first functional unit (the heat generator) and the second functional unit (for operating the heating system) into two modules, easy transport into an interior space, such as a boiler room, is possible. Furthermore, the first and second support structures allow for a space-saving, simple, and targeted arrangement of the modules within the interior space. The necessary pipes are also largely already correctly positioned on the modules, so that only the corresponding inlet and outlet connections of the modules need to be connected. Given that these inlet and outlet connections are fixed to their respective support structures, this can be done quickly and with minimal error.Due to the known arrangement of the aforementioned outlet and inlet connections on the support structures, prefabricated rigid connecting pipes can be used, which do not need to be shortened or lengthened on site. The flat design of the support structures also allows for good accessibility to the functional units as well as the supply and return lines.

[0009] In a preferred embodiment of the kit according to the invention, the kit further comprises an additional module that is designed separately from the first and second modules. This additional module includes a flat support structure, a further functional unit for operating the heating system attached to the support structure, a further supply line which is attached to the support structure to provide a fixed inlet end, and a further return line which is attached to the support structure to provide a fixed outlet end. The further functional unit could, for example, be an electrical distribution box or a circulation pump.In principle, the additional module can also include two or more additional supply and / or return lines, which are attached to the additional support structure in a corresponding manner.

[0010] In order to securely support the modules of the kit, in particular their functional unit as well as the supply and return lines, within the interior of a building, the first and second support devices, and optionally also the further support device, in an advantageous embodiment of the kit according to the invention, comprise a support frame consisting of several support struts. The support struts can, for example, be made of metal. The support frame can also preferably be formed by a surrounding frame, and it is further preferred if at least one support strut extends within the frame.

[0011] In a further advantageous embodiment of the kit according to the invention, the first support structure and the second support structure, and optionally also the further support structure, have at least one plate attached to the support frame for at least partially covering at least one opening in the support frame. Thanks to the plate, components of the heating system can be effectively separated from one another, for example, a front side where the functional units and the flow and return lines are easily accessible, from a rear side of the respective support structure, along which electrical lines may be routed that should not be so easily accessible to the customer after installation. Moreover, the plate attached to the support frame contributes to the stabilization of the support frame.Notwithstanding the above, in this embodiment it is preferred if the functional unit and / or the supply line and / or the return line is attached to the respective support structure via the support frame in order to ensure secure support of the aforementioned components via the support structure.

[0012] In a particularly preferred embodiment of the kit according to the invention, the functional unit of at least one module, together with its outer housing, is arranged on the associated support structure, preferably attached to the support structure via the outer housing. For the respective functional unit, in particular the heat generator, a commercially available functional unit, including its outer housing, can thus be used. This housing can be easily and quickly attached to the support structure and simultaneously prevents or at least restricts unwanted or unintentional access to the internal components of the functional unit. The flow and return lines of the respective module, on the other hand, are arranged outside the associated outer housing and attached to the associated support structure to allow quick access during assembly or maintenance.

[0013] In a further advantageous embodiment of the kit according to the invention, the functional unit, the supply line, and the return line of the respective module are arranged at a distance from a longitudinally extending end on the support device. The respective module can, for example, be supported in a predefined manner on an interior floor via this end of the support device, while the functional unit, the supply line, and the return line can be arranged at a convenient and easily accessible height.

[0014] In a further advantageous embodiment of the kit according to the invention, the functional unit, the supply line, and the return line of the respective module are arranged on a front side of the associated support structure that points in the direction of depth, in order to ensure easy access to these components. It is preferred that the functional unit, the supply line, and the return line do not protrude beyond a rear side of the associated support structure that faces away from the front side—i.e., that points in the opposite direction of depth.

[0015] In a particularly advantageous embodiment of the kit according to the invention, the heat generator forming the first functional unit is a heat pump, preferably an indoor unit of a split heat pump. The indoor unit particularly preferably includes a condensing unit for the refrigerant of the heat pump. In principle, the indoor unit can also include a compression unit and / or an expansion unit for the refrigerant of the heat pump. The condensing unit, and optionally also the compression unit and / or expansion unit, is preferably arranged within the aforementioned outdoor housing.

[0016] In a further advantageous embodiment of the inventive kit, the second or further functional unit is a circulation pump for the heating medium of the heating system. The circulation pump is preferably connected to the second or further supply line at its inlet, i.e., via the pump inlet, in order to pump the heating medium from the second or further supply line. Due to the generally light weight and small installation space required by a circulation pump, it is also preferred in this embodiment if the circulation pump is indirectly attached to the second or further support structure via the second or further supply line. This eliminates the step of directly attaching the circulation pump to the support structure, and the attachment of the second or further supply line also serves to secure the circulation pump, thus simplifying assembly and installation.

[0017] In a further advantageous embodiment of the kit according to the invention, the circulation pump is configured such that it can be controlled by a control unit of the heat generator. Corresponding control lines can be laid, for example, on the back of the support structures after the modules have been erected. However, wireless control is also possible.

[0018] In a further advantageous embodiment of the kit according to the invention, the second or further functional unit is an electrical distribution unit. The electrical distribution unit is preferably configured such that electrical energy can be distributed to one or more functional units of the heating system and / or the kit. It is particularly preferred if electrical energy can be distributed to the heat generator and / or an additional electric heat generator associated with the heat generator, optionally a heating element. Corresponding power cables can be laid, for example, on the back of the support structures after the modules have been erected. It is particularly preferred if the electrical distribution unit has at least two sockets into which the plugs of the power cables can be easily inserted.In this context, it has proven advantageous if the plate of the second or subsequent support device has at least one opening for the cable with the plug to pass through. This way, the plug is easily accessible and can be easily connected to or disconnected from the socket, while the associated power cable can run on the opposite side of the support device, where it does not cause any obstruction.

[0019] In a further preferred embodiment of the kit according to the invention, the first and second support devices, and optionally also the further support device, have a length that is greater than the width of the respective support device in order to ensure an arrangement of the functional unit at an adequate and easily accessible height, while the support devices can be designed to save space in the width direction.

[0020] In order to ensure both secure support and a space-saving arrangement, the first and second support devices, and optionally also the further support device, in a further preferred embodiment of the kit according to the invention have a depth that is smaller than the length and width of the respective support device, wherein the depth is preferably less than 10 cm, and particularly preferably less than 5 cm.

[0021] In a further preferred embodiment of the kit according to the invention, the first and second support devices, and optionally also the further support device, have essentially the same length, optionally also the same width and / or depth, in order to ensure, on the one hand, simplified manufacturing of the modules and, on the other hand, to make it particularly easy to arrange or / and align the support devices relative to each other during assembly.

[0022] As previously indicated, the fixed inlet and outlet ends on the respective support structure allow for simple, predefined positioning of the modules relative to each other when they are arranged and aligned. Furthermore, rigid connecting lines can be prefabricated to connect the inlet and outlet ends of different modules. In a further preferred embodiment of the kit according to the invention, the kit therefore also includes rigid connecting lines, separate from the modules, for directly or indirectly connecting an outlet end of one module to an inlet end of another module.The multiple connecting lines are preferably designed such that the outlet and inlet lines can be connected to each other in a predetermined relative position of the first module and the second module, and optionally also of the further module, without shortening or lengthening the connecting lines.

[0023] The method according to the invention serves to construct a heating system, preferably a part of a heating system, in a building, using the process steps described below. First, a kit according to one embodiment of the aforementioned inventive type is provided. Then, the first module and the second module, and optionally also the further module, are arranged within an interior space of the building in a relative position to each other, in which the first support structure and the second support structure, and optionally also the further support structure, extend in their longitudinal and transverse directions in a common plane. Subsequently, the first and second support structures, and optionally also the further support structure, are fixed in their relative position to each other.This method not only allows the modules to be easily and separately transported into the building's interior, but also creates a space-saving, single-level support structure for the functional units, supply lines, and return lines, which are particularly easy to access. Furthermore, the complex assembly of the functional units is eliminated, and a large portion of the necessary routing of supply and return lines is already completed through integration into the respective module. This means that only the inlet and outlet connections need to be made, preferably using the prefabricated rigid connecting pipes from the kit described earlier.

[0024] In a preferred embodiment of the method according to the invention, the first and second support devices, and optionally also the further support devices, are fixed in their relative position to each other by attaching the first and second support devices to each other, and optionally also the further support device to the first or second support device.

[0025] In a particularly preferred embodiment of the method according to the invention, the first module and the second module, and optionally also the further module, are arranged such that the first and second support devices, and optionally also the further support device, are adjacent to each other in their relative position and / or are supported against each other. This ensures to a particularly high degree that the fixed outlet and inlet ends of the modules assume the desired predetermined position relative to each other and that the prefabricated rigid connecting lines can be installed safely and easily.

[0026] In an advantageous embodiment of the method according to the invention, the first module and the second module, optionally also the further module, or the mutually attached support devices of the first module and the second module, optionally also the further module, are arranged in a desired position in the interior. In the desired position, the first and second modules, optionally also the further module, are supported on an interior floor by means of the first and second support devices, optionally also the further support device, preferably by means of the aforementioned longitudinally projecting end of the respective support device. Alternatively or additionally, the common plane of the support devices in the desired position corresponds to a vertical plane in order to create an upright overall support structure that is particularly load-bearing and ensures simple assembly as well as good accessibility.Alternatively or additionally, the backs of the support devices are spaced away from a wall of the interior in the intended position to create a space on the side of the support devices facing away from the functional units, in which, for example, power and control lines can be laid.

[0027] In a further advantageous embodiment of the method according to the invention, the first module and the second module, and optionally also the further module, are fixed in the desired position within the interior space. This can be achieved, for example, by means of brackets, rails and / or struts between the interior floor, interior wall and / or interior ceiling on the one hand and one or more support devices of the kit on the other.

[0028] In a further advantageous embodiment of the method according to the invention, providing the kit comprises the process steps of manufacturing the first module and the second module, and optionally also the third module, outside the interior of the building, for example in a production hall, and transporting the first module and the second module, and optionally also the third module, into the interior of the building. As already indicated above, transport into the interior is particularly easy, even in relatively difficult-to-access rooms. Furthermore, the prefabrication of the modules increases manufacturing accuracy.

[0029] The invention is explained in more detail below with reference to an exemplary embodiment and the accompanying drawings. These show: Fig. 1 a front view of an embodiment of the kit according to the invention with separately designed modules and connecting lines, Fig. 2 a flowchart to illustrate an embodiment of the inventive method for constructing a heating system in a building using the kit according to Fig. 1, Fig. 3 a front view of the kit made of Fig. 1 after arranging and fixing the modules in their relative position to each other and fixing them in the target position within an interior space of the building, Fig. 4 a side view of the arrangement Fig. 3 in the direction of arrow A and Fig. 5 the front view from Fig. 3 in conjunction with other components and functional units of the heating system, at least schematically indicated.

[0030] Fig. Figure 1 shows a kit 2 for a heating system 4 of a building, with the other components of the heating system 4 in Fig. 5 are at least indicated. Kit 2 comprises a first module 6, a second module 8, and a further or third module 10, with the first, second, and third modules 6, 8, and 10 being designed separately from one another. The components of modules 6, 8, and 10, described in more detail below, are securely connected to one another. In addition, kit 2 comprises several rigid connecting lines 12, 14, 16, and 18, which are designed separately from each other and from the aforementioned modules 6, 8, and 10. In Fig. In Figure 1 as well as in the following figures, the opposing longitudinal directions 20, 22, the opposing latitude directions 24, 26 and the opposing depth directions 28, 30 of the modules 6, 8, 10 are indicated by corresponding arrows.

[0031] Modules 6, 8, and 10 each have a planar support structure. Specifically, the first module 6 has a first support structure 32, the second module 8 has a second support structure 34, and the third module 10 has a third support structure 36. A planar support structure 32, 34, or 36 is preferably understood to be a support structure that extends substantially in a plane or surface. Thus, the first, second, and third support structures 32, 34, and 36 of the illustrated embodiment extend substantially in the plane or surface of the drawing. These support structures 32, 34, and 36 each have a length l in the longitudinal directions 20 and 22, a width b in the lateral directions 24 and 26, and a depth t in the lateral directions 28 and 30, where the depth t is determined in particular by the Fig. 4 can be taken from the diagram. The length l is greater than the width b of the respective support device 32, 34, 36, while the depth t is smaller than both the length l and the width b of the respective support device 32, 34, 36. To create a support device 32, 34, 36 that is as space-saving as possible, the depth t is preferably less than 10 cm, and particularly preferably less than 5 cm. Furthermore, the following applies: Fig. 1 It is evident that all three support devices 32, 34, 36 advantageously have the same length l and the same width b and the same depth t.

[0032] The support devices 32, 34, 36 are each composed of a support frame 38 and at least one plate 40 attached to the support frame 38, the latter being, as in particular from Fig. As can be seen in Figure 4, the support frame 38 is attached to the side of the support frame 38 that points in the depth direction 30 in order to cover openings in the support frame 38. The support frames 38 of the support devices 32, 34, 36 are composed of several support struts. The support frames 38 have two longitudinal struts 42, 44 extending in the longitudinal direction 20, 22 and spaced apart in the width direction 24, 26, the ends of which point in the longitudinal direction 20 are connected to each other by a cross strut 46 and the ends of which point in the longitudinal direction 22 are connected to each other by a cross strut 48, the cross struts 46, 48 extending in the width directions 24, 26 and together with the longitudinal struts 42, 44 forming a substantially rectangular support frame of the support frame 38. Furthermore, the support frame 38 has at least one additional cross brace 50 located inside the support frame.While the support frame 38 of the second support device 34 has no further internal support struts, the support frame 38 of the first support device 32 has an additional internal cross strut 52, and the support frame 38 of the third support device 36 has additional internal cross struts 54, 56. Furthermore, the support frame 38 of the first support device 32 has an internal longitudinal strut 58, which extends between the cross strut 52 and the cross strut 48 in the longitudinal directions 20, 22.

[0033] Each of the three modules 6, 8, 10 shown has a functional unit for operating the building's heating system 4. A first functional unit 60 is attached to the first support structure 32, a second functional unit 62 to the second support structure 34, and a third functional unit 64 to the third support structure 36. In the illustrated embodiment, the first functional unit 60 is a heat generator 66, the second functional unit 62 is a circulation pump 68, and the third functional unit 64 is an electrical distributor 70. The functional units, in the form of the heat generator 66, the circulation pump 68, and the electrical distributor 70, are arranged on the front face of the respective support structure 32, 34, and 36, respectively, pointing in the depth direction 28.64 preferably does not protrude beyond a rear side of the associated support device 32, 34 or 36 facing away from the front and pointing in the depth direction 30, as shown in . Fig. 4 for the heat generator 66 in conjunction with the first support device 32 is indicated. In particular, any connections, cables or lines for connecting the respective functional unit 60, 62, 64 should protrude from the rear of the respective support device 32, 34 or 36, which faces backwards in the depth direction 30.

[0034] The heat generator 66 is a heat pump, more precisely the indoor unit of a split heat pump. The heat generator 66 has a closed outer casing 72 that surrounds its components, and the heat generator 66 is attached to the first support structure 32, more precisely to the support frame 38, via the outer casing 72. Fig. 1. The corresponding fastening means 74 for attaching the outer housing 72 to the support frame 38 of the first support device 32 are schematically indicated; these may, for example, be screwed-on brackets. In addition, in Fig. Figure 1 schematically indicates the other components of the heat generator 66 arranged within the outer casing 72. In particular, the heat generator 66 has a condensing unit 76 for the refrigerant of the heat pump. Although not strictly necessary, a compression unit 78 and / or an expansion unit 80 for the refrigerant of the heat pump may also be provided within the outer casing 72 of the heat generator 66; however, these could also be located in an outdoor unit of the heating system 4 (not shown). In any case, the heat generator 66, which is designed as the indoor unit of a heat pump, has two connections 81 for integrating the heat generator 66 into a refrigerant circuit.Furthermore, an additional electric heat generator 82, associated with the heat generator 66, is arranged in the outer housing 72. This additional electric heat generator 82 can, for example, be a heating element that can supplement or replace the heat generator 66 as needed. The heat generator 66 also has a control unit 84 inside the outer housing 72 for controlling the heat generator 66. In addition, the heat generator 66 has a heating medium outlet 86, another heating medium outlet 88, and a heating medium inlet 90. Water is preferably used as the heating medium for the heating system 4.

[0035] Outside the outer casing 72 of the heat generator 66, a first supply line 92, a further first supply line 94, and a first return line 96 are arranged on the front face of the first support structure 32, which points in the direction of depth 28. These lines are attached to the support frame 38 of the first support structure 32 via fastening points 98. The fastening at the fastening points 98 can be effected, for example, by means of struts projecting in the direction of depth 28, which are Fig. Figure 4 indicates the following. The first supply line 92 is connected to the heating medium outlet 86 of the heat generator 66, while the second first supply line 94 is connected to the heating medium outlet 88 of the heat generator 66. The first return line 96, on the other hand, is connected to the heating medium inlet 90 of the heat generator 66. Due to the mounting of the first supply lines 92, 94 and the first return line 96, which are preferably rigid lines, the first supply line 92 and the second supply line 94 each have a first outlet end 100, 102 fixed to the first support device 32, while the first return line 96 has a first inlet end 104 fixed to the first support device 32.

[0036] Similar to the first module 6, the second module 8 also has at least one supply line and at least one return line. Specifically, the second module 8 has a second supply line 106, a further second supply line 108, and a second return line 110, which are in turn attached to the support frame 38 of the second support structure 34 via fastening points 98. The second supply line 106 has a second inlet end 112, with the first supply line 106 being connected at its end opposite the second inlet end 112 to the inlet side of the circulation pump 68. The second supply line 108, on the other hand, has a second outlet end 114, with the second supply line 108 being connected at its end opposite the second outlet end 114 to the outlet side of the circulation pump 68. The second return line 110, however, has a second inlet end 116 and a second outlet end 118.Thanks to the attachment of the essentially rigid supply lines 106, 108 and the return line 110 to the second support structure 34, the second inlet end 112 and the second outlet end 114 of the two second supply lines 106, 108 are essentially fixed to the second support structure 34. The same applies to the second inlet end 116 and the second outlet end 118 of the second return line 110, which are also essentially fixed to the second support structure 34. In principle, the circulation pump 68 – like the heat generator 66 of the first module 6 – can be attached to the second support structure 34 via the support frame 38 of the second support structure 34, or optionally via an outer housing of the circulation pump 68.In the illustrated embodiment, however, the circulation pump 68 is neither directly attached to the support frame 38 nor to the plate 40 of the second support device 34; rather, the circulation pump 68 is indirectly attached to the second support device 34 via the second supply line 106 and the second supply line 108, specifically via the aforementioned attachment points 98 on the support frame 38. Furthermore, the circulation pump 68 is configured such that, after the installation of the heating system 4, which will be described in more detail later, it can be controlled by the control unit 84 of the heat generator 66.

[0037] In analogy to the first and second modules 6, 8, the third module 10 also has at least one supply line and one return line, which are attached to the support frame 38 of the third support structure 36 via fastening points 98 on the front side of the third support structure 36, which faces in the direction of depth 28. Thus, the third module 10 has a third supply line 120 with a third inlet end 122 and a third outlet end 124, and a third return line 126 with a third inlet end 128 and a third outlet end 130. The third inlet ends 122, 128 and the third outlet ends 124, 130 are again fixedly arranged on the third support structure 36 due to the fastening of the rigidly designed supply and return lines 120 and 126, respectively.

[0038] The electrical distribution box 70 of the third module 10 is configured such that electrical energy can be distributed to one or more functional units of the heating system 4 or the assembly kit 2. In particular, the electrical distribution box 70 is configured such that electrical energy, preferably in the form of high-voltage current, can be distributed to the heat generator 66 of the first module 6 and to the additional heat generator 82 associated with the heat generator 66. For this purpose, the electrical distribution box 70 has at least two sockets 132, one of which can be used to supply power to the heat generator 66 and the other to supply power to the additional electric heat generator 82.In order to avoid having to route the corresponding lines on the connector along the front of the support devices 32, 34, 36, at least one opening for the insertion of the connector or cable is provided in the plate 40 of the third support device 36.

[0039] From the preceding description of modules 6, 8, 10, it is evident that the functional units 60, 62, 64 and the supply and return lines of the respective module are not only arranged on the front side of the respective support device 32, 34 or 36, which points forward in the depth direction 28, but rather the functional units 60, 62, 64, the supply lines 92, 94; 106, 108; 120 and the return lines 96; 110; 126 of the respective module 6, 8, 10 is attached to the support device 32, 34, 36 at a distance from an end of the associated support device 32, 34, 36 pointing in the longitudinal direction 22, in order to be able to securely support the aforementioned components of the modules 6, 8, 10 via the aforementioned end 136 against an interior floor within the building which will be described in more detail later.In the embodiment shown, said end 136 is essentially formed by the crossbar 48 and / or the longitudinally 22 pointing ends of the longitudinal struts 42, 44 of the support frame 38.

[0040] A further special feature of the first module 6 is that the first supply lines 92, 94 have additional inlet ends 138 and 140 respectively, while the first return line 96 has an additional outlet end 142. This allows for the alternative or supplementary use of another heat generator within the building, for example, a gas boiler, an oil boiler, or a wood pellet boiler. Another special feature of the third module 10 is that a potable water line 144 is arranged on the front of the third support structure 36 and is attached to the third support structure 36 via the support frame 38. The potable water line 144 has an inlet end 146 and an outlet end 148, which are fixedly attached to the third support structure 36.

[0041] The essentially rigid connecting lines 12 to 18 serve to directly or indirectly connect one of the described outlets of one of the modules with one of the described inlets of one of the other modules, wherein the connecting lines 12 to 18 are designed such that the outlets and the inlets can be connected to each other in the predetermined relative position of the first module and the second module, and optionally also the third module, as described in more detail later, without shortening or lengthening the connecting lines 12 to 18.

[0042] Below is an embodiment of the method for constructing the in Fig. 5 heating system 4 of a building shown with reference to Fig. 2 in connection with the Fig. 1, 3 to 5 are described. These are in the Fig. 3 and Fig. 5. For the sake of clarity, not all reference symbols are shown. Fig. 1 is reproduced, but all the associated components are present.

[0043] In process step 150, the preceding with reference to Fig. The components of the kit 2 described in section 1 are manufactured outside the building with the heating system 4, namely in particular the first module 6, the second module 8, the third module 10 and the rigid connecting lines 12 to 18. The manufacture of the aforementioned components of the kit 2 is preferably carried out by the manufacturer in a factory hall.

[0044] Once the components of kit 2 have been manufactured, process step 152 involves transporting the first module 6, the second module 8, the third module 10, and the connecting lines 12 to 18 into an interior space of the building containing the heating system 4, which is to be erected or completed using kit 2. This step already demonstrates an advantage of using kit 2, as the individual modules 6, 8, and 10 can be moved separately into relatively difficult-to-access interior spaces, such as boiler rooms, within a building. Each module 6, 8, and 10 already contains essential and properly connected components of the heating system 4 to be erected. Therefore, kit 2, along with its components, can be transported relatively quickly into the interior of the building containing the heating system 4.

[0045] If the kit 2 is provided within the interior of the building in the manner described above, then in process step 154 ​​the first module 6, the second module 8 and the third module 10 are arranged within the interior in a relative position to each other which is Fig. Figure 3 indicates that in the relative position, the first support device 32, the second support device 34, and the third support device 36 extend in their longitudinal directions 20, 22 and their lateral directions 24, 26 in a common plane. In the illustrated embodiment, the modules 6, 8, and 10 are arranged such that the support devices 32, 34, and 36 adjoin and are supported against each other in the lateral direction 24, 26. In this specific embodiment, the longitudinal strut 44 of the first support device 32 is supported in the lateral direction 24 against the longitudinal strut 42 of the second support device 34, while the longitudinal strut 44 of the second support device 34 is supported in the lateral direction 24 against the longitudinal strut 42 of the third support device 36, in order to arrange the modules 6, 8, and 10 in the desired relative position.Since the support devices 32, 34, 36 are arranged in a common plane, and since the aforementioned support devices 32, 34, 36 also have the same length l, both the cross braces 46 and the cross braces 48 are aligned with each other in the lateral directions 24, 26. Furthermore, the longitudinally projecting ends 136 of the support devices 32, 34, 36 form a support end arranged along a straight line for the modules 6, 8, 10, which are arranged in the desired relative position.

[0046] Subsequently, in process step 156, the support devices 32, 34, 36 are fixed in their relative position to one another, whereby in the illustrated embodiment this is done by fastening the support devices 32, 34, 36 to one another. This is achieved, for example, by means of fasteners 158, 160, which connect, on the one hand, the support frame 38 of the first support device 32 to the support frame 38 of the second support device 34 and, on the other hand, the support frame 38 of the second support device 34 to the support frame 38 of the third support device 36, in order to effect a corresponding fixation.

[0047] Even during the arrangement of modules 6, 8, 10 in their relative positions to one another and / or during the fixing of modules 6, 8, 10 in their relative positions to one another, the position of modules 6, 8, 10 can correspond to their later target position in the interior of the building. Alternatively, however, modules 6, 8, 10 can also first be placed on the interior floor 162 with the rear side of the support devices 32, 34, 36 facing in the depth direction 30, arranged in their relative positions to one another, and then fixed together in order to subsequently transfer the fixed modules 6, 8, 10 to their target position within the interior, which is particularly relevant in the Fig. 3 and Fig. Figure 4 shows that in this intended position, the three modules 6, 8, 10 are supported on the interior floor 162 by the longitudinally projecting ends 136 of the support devices 32, 34, 36, while the aforementioned common plane in which the support devices 32, 34, 36 extend is a vertical plane. In other words, the longitudinal directions 20, 22 of the modules 6, 8, 10 in the intended position correspond to opposite vertical directions. Moreover, the rear faces of the support devices 32, 34, 36, which point in the depth direction 30 of the modules 6, 8, 10, are spaced from a wall 164 of the interior, as shown in Figure 4. Fig. 4 is indicated by the distance a.

[0048] Furthermore, the modules 6, 8, 10 are fixed in their intended position within the interior in process step 166, whereby in the illustrated embodiment this is done by way of the fastening means 160 designed as angles on the interior floor 162 and by way of the fastening means 168 designed like angles on the wall 164.

[0049] In a further process step 170, the functional connection of modules 6, 8, 10 to each other takes place, in particular with the help of the connecting lines 12 to 18 of kit 2, as shown in Fig.As indicated in Figure 5, connecting line 12 is used to connect the first outlet 100 of the first module 6 to the second inlet 112 of the second module 8. Furthermore, connecting line 114 is connected on one side to the first outlet 102 of the first module 6 and on the other side to the third inlet 122 of the third module 10. Additionally, connecting line 16 is connected to the second outlet 118 of the second module 8 to create the indirect connection, described in more detail later, to the first inlet 104 of the first module 6. Connecting line 18, on the other hand, is connected on one side to the first inlet 104 of the first module 6 and on the other side to the third outlet 130 of the third module 10.

[0050] Subsequently, in process step 172, the created arrangement is fully integrated into the building's heating system 4. The second outlet 114 of the second module 8 is connected to the building's supply line to supply the heating medium to radiators 174, while the connection of the second inlet 116 of the second module 8 to the building's return line allows the heating medium to return from the radiators 174.

[0051] Furthermore, the end of the connecting line 16 opposite the second outlet 118 of the second module 8 is connected to a buffer storage tank 176 of the heating system 4, which is also connected to another inlet 178 in the connecting line 18. In addition, the buffer storage tank 176 can be connected to, or is connected to, an inlet / outlet 180 in the connecting line 12.

[0052] The third outlet end 124 of the third module 10 is connected to an inlet side of a heat exchanger 182, which serves to transfer heat to potable water in a potable water storage tank 184, with the third inlet end 128 of the third module 10 being connected to the outlet side of the heat exchanger 182. The inlet end 146, on the other hand, is connected to the interior of the potable water storage tank 184 in order to draw potable water from the potable water storage tank 184 via the potable water line 144 of the third module 10, with the outlet end 148 of the potable water line 144 also being connected to a potable water line of the building in order to draw potable water at potable water draw-off points 186 of the building.

[0053] As already indicated above, an alternative or supplementary additional heat generator 188 can also be connected via the additional inlet ends 138, 140 and the additional outlet end 142 of the first module 6.

[0054] While the additional heat generator 180, the domestic hot water storage tank 184, and the buffer storage tank 174 are preferably arranged in the same interior space, an outdoor unit 190 of the heat pump is located outside the building. The outdoor unit 190 comprises an evaporation device 192 and, optionally, the previously described compression and / or expansion device 78, 80 for the refrigerant. During integration, the connections 81, 81 are connected to the outdoor unit 190 via refrigerant lines.
