- a compressor;

- an evaporator with a primary evaporator side and a secondary evaporator side for the extraction of heat from the primary evaporator side and the delivery of that heat to the secondary evaporator side;

- a condenser with a primary condenser side and a secondary condenser side for the extraction of heat from the primary condenser side and the delivery of that heat to the secondary condenser side; and

- a medium circuit,

wherein the secondary evaporator side and the primary condenser side are incorporated in the medium circuit, and wherein the compressor is incorporated in the medium circuit downstream of the evaporator.

Devices of this type are generally known for the transport of heat. An example of an application is the refrigerator, in which heat is transported from the refrigerator via the medium circuit to the air outside the refrigerator.

An object of the invention is to provide an improved heat transport device.

For this purpose, the invention provides, in a first aspect of the invention, for a heat transport device according to the preamble of claim 1 , characterized in that the heat transport device comprises an attachment part to attach the heat transport device to a wall or ceiling, and a subframe, wherein the subframe is resiliently arranged relative to the attachment part, and wherein the compressor is arranged onto the subframe. An advantage of a heat transport device according to the first aspect of the invention is that vibrations from the compressor are thereby damped and can cause no or virtually no interfering noise or damage. Components other than the compressor can possibly be connected directly or indirectly to the attachment part, but may also be positioned on the subframe.

In a different embodiment, the heat transport device comprises a boiler which is disposed on the subframe. The boiler, which preferably has a content of 50L, adds a relatively large mass (certainly when filled with water) to the subframe, causing vibrations in the subframe to be damped already by the presence of the boiler. In an embodiment, the heat transport device comprises a housing, wherein the subframe is resiliently arranged in the housing, and wherein the housing together with the subframe is to be detachably attached to the attachment part. This does not mean that the housing and the subframe are per se permanently connected to one another, but merely that the housing and the subframe are to be simultaneously detachably attached to the attachment part. The arranging of the subframe in the housing relates only to the location of the subframe in relation to the housing. In an embodiment, the housing can also be attached to the attachment part separately from the subframe. The resilient arranging of the subframe in the housing indicates that possible direct contact between the subframe and the housing takes place on the attachment part side of the resilient elements with which the subframe is arranged in relation to the attachment part. In other words, the housing and the subframe are each arranged directly on the attachment part. The advantage of this is that the forces from the subframe do not have to be directed first through the housing in the direction of the attachment part, as a result of which vibrations occur in the housing and may be amplified. The forces are then directly absorbed on the attachment part, resulting in a substantial noise reduction.

The housing can serve to protect components of the heat transport device, but can also be used to suspend or attach other components of the device on or to it. The housing is preferably soundproof. Even more preferably, the housing is made of metal to provide effective soundproofing characteristics.

The facility for detachable positioning of the housing with the subframe provides for an easy- to-install system. Firstly, the attachment part can simply be attached to a wall or ceiling, whereafter the rest of the heat transport device can be detachably arranged.

Connections between components on the subframe and components attached to the housing are preferably flexibly implemented.

The detachable attachment of the housing and the subframe to the attachment part is preferably implemented by means of a hook-type and/or pin connection. The attachment part can thereby be attached to the wall or ceiling and thereafter the heat transport device can be suspended in a simple manner on the attachment part and can also be removed again later for maintenance or repair. The housing is preferably arranged on the hook-type connection and/or mortise and tenon joint so that there is as little contact as possible between the housing and the subframe, as a result of which vibrations in the subframe have little to no impact on the housing. In an embodiment, the subframe is resiliently arranged on the attachment part by means of vibration dampers which are preferably arranged on the attachment part close to the detachable connection of the subframe and the housing. As a result, it can be effectively ensured for the support of the subframe that, due to the presence of the boiler, a relatively large mass can be present in comparison with the rest of the heat transport device.

In an embodiment, at least one vertically positioned vibration damper is provided which is designed to take the weight of the subframe and the components arranged thereon on the attachment part, and at least one horizontally positioned vibration damper is provided which is designed to absorb horizontal forces on the attachment part. The vertically positioned vibration dampers are preferably designed as pressure-spring elements. The vertically positioned vibration damper is preferably positioned under the subframe. The attachment part then preferably comprises a protruding part which is also positioned under the subframe. This creates a vertical stacking of the protruding part of the attachment part, the spring element and the subframe. This provides effective support for the subframe.

According to a second aspect of the invention, the invention provides for a heat transport device according to the preamble of claim 1, characterized in that the secondary condenser side has a water inlet and a water outlet which are connectable to a water circuit.

An advantage of a heat transport device according to the second aspect of the invention is that the device is suitable for the extraction of residual heat from a medium and can deliver this residual heat to a water circuit, as a result of which hot water is produced which can be usefully employed in a home as heating by means of a central heating or floor heating system, or in the form of hot (drinking) water for a shower, bath, kitchen, etc. The water circuit then forms, for example, part of a central heating system and/or a floor heating system and/or a hot water system. tn an embodiment, the heat transport device comprises a displacement apparatus for the transportation of a medium through the primary evaporator side.

The medium may be any medium from which residual heat can be extracted, but is, in particular, air or water. If residual heat is extracted from air, the displacement apparatus is preferably a fan. A fan can be dispensed with if, for example, use is made of convection currents, but this is not preferable. The advantage of a fan is that the heat transport device can also serve as a ventilation device while residual heat can simultaneously be extracted from the ventilation air. As a result, a separate ventilation system does not need to be provided and heat which would otherwise dissipate with the ventilation air from the area is recovered. If residual heat is extracted from water or a different liquid, the displacement apparatus is preferably a pump. However, use can also be made of external pumps which are already present in dishwashers, washing machines, etc., but also of gravity in the case of shower or bath water. In an embodiment, the water is collected in a reservoir, whereafter a pump feeds it along the primary evaporator side.

The water circuit which is connectable to the heat transport device may comprise a central heating installation and/or a hot water device such as a boiler, wherein the boiler may form part of the heat transport device, as will be described in further detail below.

In a different embodiment, the heat transport device comprises a three-way valve with one inlet and two outlets, wherein the three-way valve is controllable in order to distribute a flow through the inlet between the two outlets, and wherein the three-way valve is connected via its inlet to the water outlet of the secondary condenser side and is connectable via its two outlets to two branches of the water circuit.

An advantage of the three-way valve, i.e. the facility for connecting the device to two branches of the water circuit, is that the residual heat can usefully be employed for two different purposes, wherein the distribution of the residual heat, i.e. the heat transport between the two purposes, can be controlled by the three-way valve.

In a different embodiment, the heat transport device comprises a boiler with a boiler reservoir for water for domestic use, such as, for example, the provision of hot water for a shower, bath, and kitchen.

According to a third aspect of the invention, the invention provides for a heat transport device according to the preamble of claim 1 , characterized in that the heat transport device comprises a displacement apparatus for the transportation of a medium through the primary evaporator side, wherein the displacement apparatus is resiliently arranged relative to a frame.

An advantage of a heat transport device according to the third aspect of the invention is that vibrations from the displacement apparatus are not transmitted to the frame of the device and thereby interference in the form of noise and damage as a result of the vibrations is restricted to a minimum. In this context, the frame may also be a housing or subframe.

According to a fourth aspect of the invention, the invention comprises a heat transport device according to the preamble of claim 1 , characterized in that the heat transport device comprises a displacement apparatus for the transportation of a medium through the primary evaporator side, wherein the primary evaporator side is arranged in a connection piece between a first and second opening, and wherein the displacement apparatus is detachable and can be arranged as required between both the primary evaporator side and the first opening and between the primary evaporator side and the second opening.

An advantage of a heat transport device according to the fourth aspect of the invention is that the first or second opening can be selected as required as an inlet opening or outlet opening for the medium, as a result of which the installation can be simplified. A further advantage is that the displacement device can simply be detached for repair, maintenance or inspection.

The displacement device is preferably arranged in a separate detachable housing.

In an embodiment, the displacement device is resiliently arranged in reiation to a frame, wherein the displaced displacement device is preferably resiliently arranged in relation to its housing. In an alternative embodiment, the housing of the displacement apparatus is resiliently arranged in relation to the frame so that the displacement apparatus can be arranged resiliently in relation to the frame. According to a fifth aspect of the invention, the invention provides for a heat transport device according to the preamble of claim 1 , characterized in that the heat transport device comprises a three-way valve with one inlet and two outlets, wherein the three-way valve is controllable in order to distribute a flow through the inlet between the two outlets, and wherein the three-way valve is connected via its inlet to the water outlet of the secondary condenser side and is connectable via its two outlets to two branches of the water circuit, and in that the heat transport device comprises a boiler with a boiler reservoir for water for domestic use, wherein the boiler comprises a heat exchanger with a primary boiler side and a secondary boiler side for the extraction of heat from the primary boiler side and the delivery of that heat to the secondary boiler side, wherein an inlet of the primary boiler side is in liquid communication with an outlet of the three-way valve and an outlet of the primary boiler side is in liquid communication with the water inlet of the secondary condenser side for the formation of a first branch of the water circuit, and wherein the secondary boiler side is in liquid communication with the boiler reservoir. An advantage of the heat transport device according to the fifth aspect of the invention is that water in the boiler is indirectly heated up via the first branch of the water circuit. A possible leak in the condenser cannot therefore contaminate the water in the boiler, but will contaminate the water in the water circuit, wherein the water in the water circuit is preferably not used as drinking water. In an embodiment, a circulation pump is provided to circulate water through the first branch of the water circuit. In a different embodiment, the circulation pump is also designed to circulate water in a second branch of the water circuit. A circulation pump can thereby be dispensed with in relation to a device with separate circulation pumps for each branch of the water circuit.

In an embodiment, the heat exchanger of the boiler is designed as a spiral-shaped pipe in order to increase the heat-exchanging area of the heat exchanger and yet make use of a single element as a pipe.

In a sixth aspect of the invention, the invention provides for a heat transport device according to the preamble of claim 1, characterized in that the heat transport device comprises a boiler with a boiler reservoir for water for domestic use, wherein the boiler comprises a boiler condenser with a primary boiler condenser side and a secondary boiler condenser side for the extraction of heat from the primary boiler condenser side and the delivery of that heat to the secondary boiler condenser side, wherein the primary boiler condenser side is incorporated in the medium circuit, and wherein the secondary boiler condenser side is in liquid communication with the boiler reservoir.

An advantage of the heat transport device according to the sixth aspect of the invention is that heating up of the boiler water takes place separately from the heating up of the water in the water circuit.

In an embodiment, the primary boiler condenser side is incorporated in the medium circuit in parallel with the primary condenser side.

In a different embodiment, the primary boiler condenser side is incorporated in the medium circuit in series with the primary condenser side.

In a seventh aspect of the invention, the invention provides for a heat transport device according to the preamble of claim 1 , characterized in that the primary evaporator side is arranged in a connection piece between an inlet opening and an outlet opening, wherein the heat transport device is designed to deliver heat to an area via the water circuit, said area being connected to the inlet opening, and wherein the device comprises a temperature sensor and a controller, said temperature sensor being arranged in the inlet opening to measure the temperature, and said controller being designed to control the quantity of heat delivered to the area on the basis of an output of the temperature sensor. The connectable water circuit will, certainly in the case where it comprises a central heating installation or floor heating installation, be able to be used to heat an area. In an

embodiment, air will then be transported from the area along the primary evaporator side, possibly by a fan. The water circuit can then be controlled on the basis of the temperature of the air, thereby providing for an automatic temperature control of the area. By providing a temperature sensor in the inlet opening, the heat transport device which is connected to the water circuit can influence the latter on the basis of an output of the temperature sensor. This can be done via a controller which can intervene in different ways. Thus, a possibly present three-way valve, circulation pump or compressor of the heat transport device can be controlled by the controller.

In a different embodiment, the seventh aspect of the invention is combined with the fourth aspect of the invention, and both the first and the second opening can serve as an inlet opening or as an outlet opening. A temperature sensor is then preferably arranged in both the first opening and the second opening to measure the temperature in the first and second opening respectively, wherein the controller is designed to determine, on the basis of an output of the temperature sensors, which opening is used as an inlet opening and which opening is used as an outlet opening, and wherein the controller is designed to control the quantity of heat delivered to the area on the basis of the temperature sensor associated with the opening which is used as an inlet opening. The heat transport device then has the facility to be installed and itself to determine automatically which opening is used as an inlet opening and therefore on the basis of which temperature sensor the temperature in the area must be controlled.

The temperature sensor and controller may be designed as a thermostat.

The invention also relates to a heat transport system comprising:

- a heat transport device according to one of the preceding claims, and

- a second heat transport device arranged in at least one of the two branches of the water circuit to heat the water in the at least one of the two branches of the water circuit with the aid of fossil fuels or electricity.

An advantage of a heat transport system according to the invention is that the second heat transport device can provide assistance if the heat transport device is not able to meet the energy requirement. The second heat transport device is preferably a high-efficiency boiler or a high-efficiency combination boiler.

In an embodiment, the heat transport device and the second heat transport device are incorporated in parallel with one another in a central heating water circuit.

In a different embodiment, the heat transport device and the second heat transport device are incorporated in series with one another in a central heating water circuit.

In a further different embodiment, the heat transport device comprises a boiler which is incorporated in series with a hot water device of the second heat transport device in a hot water supply circuit. It must be noted that, where possible, different aspects of the invention can be combined with one another and can also be used in a heat transport system according to the invention.

In particular, the first and third aspect can be combined in order to restrict the interfering noise from the heat transport device to a minimum. This can possibly be combined with the measure to fill an area around the compressor with soundproofing material. This measure may also possibly be used separately with the preamble to claim 1.

The invention will now be described in a non-limiting manner with reference to a drawing, in which:

Fig. 1 shows a heat transport device according to one embodiment of the invention;

Fig. 2 shows a heat transport device according to a different embodiment of the invention;

Fig. 3 shows a heat transport system according to one embodiment of the invention;

Fig. 4 shows in detail a part of a heat transport device according to one embodiment of the invention in a non-assembled condition; and

Fig. 5 shows in detail the part shown in Fig. 4 in an assembled condition.

Fig. 1 shows a heat transport device according to one embodiment of the invention. The heat transport device comprises a compressor 10, an evaporator 21, a condenser 17 and a medium circuit A.

The condenser 21 has a primary evaporator side and a secondary evaporator side for the extraction of heat from the primary evaporator side and the delivery of that heat to the secondary evaporator side, wherein the secondary evaporator side is incorporated in the medium circuit A.

The condenser 17 has a primary condenser side and a secondary condenser side for the extraction of heat from the primary condenser side and the delivery of that heat to the secondary condenser side, wherein the primary condenser side is incorporated in the medium circuit A. The compressor 10 is incorporated in the medium circuit downstream of the evaporator.

The secondary condenser side has a water inlet 17a and a water outlet 17b which are connectable to a water circuit.

The evaporator 21 is arranged in an area 20 whose walls form a connection piece between a first opening 30a and a second opening 30b. The compressor 10, the condenser 17 and the largest part of the medium circuit A are arranged in an area 1 which is preferably thermally isolated from the area 20.

The primary evaporator side is connected to the area 20. A displacement apparatus in the form of a fan 27 is arranged between the evaporator and the second opening 30b for the displacement/transportation of a medium, in this case air, through the primary evaporator side.

In this embodiment, the fan 27 is attached to a subframe 26 which is resiliently suspended on a detachable housing 22 by means of vibration dampers 25. A flexible area inlet 29 is also provided which ensures an air seal between the housing 22 and the subframe 26. The advantage of the resilient incorporation of the fan is that vibrations are damped and cannot cause any noise overload or damage. The flexible air inlet 29 contributes here also.

By being detachable, the housing and therefore the fan can be arranged as required between the evaporator and the second opening as shown in Fig. 1 , but also between the evaporator and the first opening. The air stream can thus be directed in a simple manner as required from the first opening to the second opening or vice versa, as a result of which the installation and connections to the openings can be simply arranged without having to make complicated bends in connections. In the area 20, a filter 24 is arranged between the evaporator and the first opening to filter the air which flows through the primary evaporator side. The filter 24 is preferably designed as a grease filter.

The assembly of the compressor 10, evaporator 21, condenser 17 and medium circuit A forms a heat pump, wherein heat can be extracted from the air which flows through the primary evaporator side and can be delivered to water that is transported through the secondary condenser side. Given that the operating principle of a heat pump of this type is already known, it will not be examined here in further detail. If heat is extracted in the primary evaporator side, moisture from the air may possibly condense. The heat transport device therefore comprises a condensate collection vessel 23 which can remove the condensate in the direction of a drain or other type of removal means (not shown further in Fig. 1).

The heat transport device comprises a three-way valve 54 with one inlet 54a and two outlets 54b, 54c, wherein the three-way valve is controllable in order to distribute a flow through the inlet 54a between the two outlets, and wherein the three-way valve is connected via its inlet 54a to the water outlet 17b of the secondary condenser side and is connectable via its two outlets to two branches of the water circuit.

The heat transport device comprises a boiler 3 with a boiler reservoir 3a for water for domestic use. The boiler reservoir 3a is connectable to a hot water supply circuit by means of water connections 14. The boiler comprises a heat exchanger 18 with a primary boiler side and a secondary boiler side for the extraction of heat from the primary boiler side and the delivery of that heat to the secondary boiler side, wherein an inlet of the primary boiler side is in liquid communication with the outlet 54c of the three-way valve 54 and an outlet of the primary boiler side is in liquid communication with the water inlet 17a of the secondary condenser side to form a first branch of the water circuit. The secondary boiler side is in liquid communication with the boiler reservoir.

A circulation pump 52 is arranged between the heat exchanger 18 and the water inlet 17a to circulate the water through the first branch of the water circuit. The outlet 54b of the three-way valve is connectable to a second branch of the water circuit by means of the connection 13b, for example to a water supply of a central heating installation or floor heating installation. The water return pipe of the central heating installation is then connectable to the connection 13a. The first and second branch are interconnected for the circulation pump 52, so that the pump can also be used to circulate water in the second branch of the water circuit.

The heat exchanger 18 is preferably designed as a spiral-shaped pipe.

In this example, the three-way valve and the circulation pump are arranged in a separate housing 5, similar to the compressor 10 and condenser 17, which are placed in a separate housing 2. This offers the advantage that the heat transport device can be designed with a modular structure, thereby simplifying the manufacture. The area 12 in the housing 2 is preferably filled with a soundproofing material such as, for example, pulp. Vibrations from the compressor are thereby already damped at the point of origin. The heat transport device further comprises a controller 6 incorporated in the energy supply for energy-consuming components such as, for example, the compressor, fan, and circulation pump. The controller 6 is coπnectable for this purpose to an energy source such as the mains supply via the connector 15.

The heat transport device also comprises four temperature sensors 31, 50, 51 which are connected to the controller. Temperature sensors 31 are arranged in the first and second opening 30a, 30b and can be used to measure the temperature in the area from which air is extracted and thus to determine the energy requirement of the area. On the basis of an output of this sensor 31 , a controller can control the quantity of heat which the water circuit (in this case the second branch of the water circuit) delivers to the area. In this example, the controller will preferably set the three-way valve for this purpose. The sensor and controller may be designed as a thermostat to control the temperature in the area. The temperature sensors 31 are arranged for this purpose in both openings so that both the first and second opening can be used as an inlet opening by the detachable fan. On the basis of an output of both temperature sensors 31 , the controller can determine which opening is used as an inlet opening and can therefore control the heat emission in the area independently of the installation on the basis of an output of the temperature sensor in the opening which is used as an inlet opening.

In this example, the temperature sensor 50 is placed in the boiler reservoir 3a and measures the temperature of the water in the boiler, and the temperature sensor 51 measures the temperature of the water returning from the second branch of the water circuit, for example via the return pipe of a central heating installation. On the basis of the measured

temperatures of the sensors 50 and 51 , the controller can operate the three-way valve 54 and can therefore determine the distribution between the two outputs 54b and 54c. The controller preferably distributes the flow between the outputs in such a way that the branch of the water circuit with the lowest associated temperature receives the greatest part of the flow. This offers the advantage that the temperature rise for the heat pump is as low as possible, which improves efficiency.

The controller 6 can be operated by the operating panel 16. Thus, for example, the size of the area which is connected to the inlet opening can be entered, as a result of which the controller 6 automatically sets the fan to the required value.

The housing 2 with a part of the water pump, the housing 5 with the three-way valve and the circulation pump and boiler 3 are arranged on a subframe 4. The subframe 4 is resiiiently arranged in relation to the housing 11 to which the remaining components of the device are attached.

The heat transport device further comprises an attachment part 8 which serves here to attach the heat transport device to a wall (not shown). The housing 11 and therefore also the subframe 4 are detachably arranged onto the attachment part by means of a hook fastening 9a and a mortise and tenon joint 9b. Vibrations caused by the compressor 10 will then be damped, particularly by the mass of the boiler 3 and by the vibration dampers 7 between the subframe 4 and the attachment part, and interfering noise and damage will be restricted to a minimum.

In this embodiment, the housing 11 is connected to the hook fastening 9a. However, this connection is not essential. The hook fastening 9a can also be used to place only the subframe 4 on the attachment part 8, wherein the housing 11 is attached separately to the attachment part 8. As a result, the housing 11 will make minimal contact with the hook fastening and the subframe in order to minimise vibrations transmitted from the subframe to the housing.

The resilient element 7 in the mortise and tenon joint 9b protrudes beyond the housing 11 so that it can make contact with the attachment part 8. No contact is preferably made here between the housing 11 and the resilient element 7.

Due to the design of the resilient elements 7, the resilient element 7 in the mortise and tenon joint 9b transfers in particular the vertical forces, i.e. the weight, from the subframe to the attachment part 8 and the resilient element 7 in the hook fastening 9a transfers in particular the horizontal forces, thereby preventing the subframe from rotating around the mortise and tenon joint 9b.

Given that a large part of the mass of the heat transport device will be present on the subframe, the latter is designed as an L-frame, wherein the vibration dampers 7 are positioned as close as possible to the hook fastening and the mortise and tenon joint, thereby ensuring an effective transfer of the weight on the subframe onto the attachment part 8.

Fig. 2 shows a heat transport device according to a different embodiment of the invention. Corresponding components are identically numbered and a discussion of their operation and function can be found in the corresponding description of Fig. 1. The differences between the embodiment shown in Fig. 2 and the embodiment shown in Fig. 1 will be explained in detail below. Fig. 2 shows a boiler 3 with a boiler reservoir 3a for water for domestic use. The water in the boiler reservoir 3a is warmed up during operation by the boiler condenser 19, which has a primary boiler condenser side and a secondary boiler condenser side for the extraction of heat from the primary boiler condenser side and the delivery of that heat to the secondary boiler condenser side, wherein the primary boiler condenser side is incorporated in the medium circuit A. The secondary boiler condenser side is in liquid communication with the boiler reservoir. In this example, the primary boiler condenser side is incorporated in the medium circuit in series with the primary condenser side of the condenser. On both outlets 54b, 54c of the three-way valve, water connections 13b and 13c are respectively provided here for connection to two branches of a water circuit, for example for connection to two water supply pipes of separate central heating installations, or one central heating installation and one floor heating installation, or even to a first branch to heat an external boiler comparable with Fig. 1 and a second branch. A connection 13a is provided for connection to a water return pipe which returns water from both branches. In a different embodiment, two separate connections could be provided by means of a T-junction respectively for water return pipes, which converge internally in the heat transport device at the T-junction and are thus connected to the water inlet 17a of the condenser. Fig. 3 shows a heat transport system according to one embodiment of the invention. The heat transport system comprises a heat transport device 80 according to one embodiment of the invention, and, in particular, according to an embodiment comparable with the

embodiment shown in Fig. 1, wherein the heat transport device comprises connections 14 for the connection of a boiler reservoir to a hot water supply circuit and connections 13a, 13b for connection to a second branch of a water circuit.

The system furthermore comprises air pipes 30 (shown) which are connected to an inlet opening and an outlet opening of the heat transport device 80 to supply air from an area (not shown) and to remove this air, mostly to the outside. The pipes 30 make it possible to position the heat transport device at a distance from an area to be ventilated.

The heat transport device 80 further comprises an operating panel 16 which forms part of a controller and can receive its energy via the connector 15. The fan may also possibly be operated separately via an externally arranged switch 83. This switch may be located, for example, in the area to be ventilated.

A pipe 82 which can remove condensate is connected to the heat transport device 80. This condensate may form in the evaporator and can be efficiently removed in this way. The heat transport system also comprises a second heat transport device 81 , in particular a high-efficiency combination boiler. The high-efficiency combination boiler 81 is a combination boiler of a known type and comprises a hot water device with connections 85 and connections 84 for connection to a central heating installation. The boiler of the heat transport device 80 is connected in series with the hot water device of the combination boiler 81. The heat transport device 80 and the combination boiler 81 are connected in parallel with one another to the central heating installation. The condensate removal pipe 82 of the heat transport device is also connected to the condensate removal connection 86 of the combination boiler. This simplifies the pipe-work. The combination boiler is designed to heat water with fossil fuels such as gas and fuel oil and can possibly also heat using electricity from the electricity mains supply. In principle, the energy requirement is met by the heat transport device 80. However, if the heat transport device 80 cannot meet the total energy requirement, for example due to a peak demand, the second heat transport device 81 can also be connected to meet the remaining energy requirement.

Fig. 4 shows in detail how the heat transport device according to the invention can be attached to a wall. For this purpose, the heat transport device comprises a housing 11, a subframe 4, and an attachment part 8. The attachment part 8 is attached to a wall by means of screws or bolts 8a and 8b. As no substantial weight of the device is yet attached, this can be simply implemented. The heat transport device can then be detachably placed on the attachment part by means of a hook fastening 9a and a mortise and tenon joint 9b (see Fig. 5). Vibration dampers 7, to which the L-shaped subframe 4 is attached, are arranged close to the hook fastening 9a and the mortise and tenon joint 9b. The weight on the subframe can thereby be effectively transferred to the attachment part.

The vibration dampers 7 shown here have a spring device positioned at right angles to a spring device of the other vibration damper 7, wherein vibrations can be damped at least in the directions B and C.

Fig. 4 and Fig. 5 show two vibration dampers, but it is easily possible to fit a plurality of vibration dampers. Similarly, it is possible to provide a plurality of hook fastenings and mortise and tenon joints. The chosen permutation depends on the weight and the extent of vibrations expected.

As shown in Figures 4 and 5, the subframe is connected to the attachment part 8 by means of a hook 9a and a mortise and tenon joint 9b. The housing 11 is permanently connected in each case to the hook 9a, but, in the case of the mortise and tenon joint, may not be connected to the tenon, but may sit evenly on the attachment means. The advantage of this configuration is that the contact between the housing and the subframe is minimal, as a result of which vibrations cannot be effectively transferred. Similarly, most of the weight will have to be borne by the subframe and not by the housing, as a result of which a robust connection between the subframe and the attachment means is of greater value than a robust connection between the housing and the attachment means.

In an embodiment, the housing 11 may also be loosely arranged in relation to the hook fastening 9a, wherein the contact between the subframe 4 and the housing 11 is even further minimised. The housing 11 is then attached in parallel with the subframe to the attachment part 8. The housing may possibly be temporarily fixed to the subframe, for example for transportation, as a result of which the housing and the subframe can be positioned as one whole unit on the attachment part. After positioning, the temporary fixed connection can be removed so that the contact between the subframe and the housing is then minimal.

The invention can be summarised by the following clauses.
