Description

Prior ArtHybrid heating devices with a heat pump and a gas heating block are already known, which are provided to provide thermal energy for a central heating system of a household and a hot water system of a household. The heat pump supplies energy up to a specific temperature, in particular depending on a refrigerant used in the heat pump, such as up to a temperature of 55° C. The heating system and the hot water system require a higher temperature and thus an increased amount of energy is connected to the gas heating block.Disclosure of the InventionA heating system is proposed having a heating device, in particular a hybrid heating device, which has at least two heating units, and having an alternative heating unit, which is in particular designed as an electric heating block. In this context, a "hybrid heating device" is to be understood as heating devices having at least two heating units which are based on two different energy conversion principles, such as in particular a principle in which a fuel, in particular a fossil fuel, is burned in order to obtain thermal energy, and a principle in which electrical energy is converted into thermal energy. An "alternative heating unit" is to be understood in this context as a heating unit which differs from at least one and preferably from both of the at least two heating units of the heating device, namely in particular in its energy conversion principle. In this case, various configurations that appear expedient to the person skilled in the art are conceivable, but the alternative unit is particularly advantageously designed as an electric heating block, namely preferably with resistance heating elements, so that in particular the heating system can be operated completely electrically. Furthermore, at least one heating unit of the heating device and / or the alternative heating unit can be designed as a hydrogen heating unit.The alternative heating unit can already be at least partially preinstalled and thus in particular provided as a replacement for at least one of the heating units of the hybrid heating unit. Alternatively, however, at least one of the two heating units of the heating device is preferably provided for replacement with the alternative heating unit, and more particularly preferably by an end customer. In this context, "provided" is to be understood as meaning specially equipped, specially designed and / or specially programmed. Plug connections are preferably provided, by means of which the alternative heating unit can be installed electrically and preferably also in a simple manner with regard to control technology and a so-called plug-and-play solution can thus be achieved. In this case, the heating unit to be exchanged can only be deactivated or else deactivated and removed.A particularly high flexibility can be achieved by a corresponding configuration, specifically with regard to the use of fuel and electric current, and with regard to a required energy requirement and temperatures in the system, and specifically in particular also after installation. It can be reacted particularly advantageously to changes, such as, for example, to a lower energy requirement on account of newly installed thermal insulation, changed availability, for example by installing a PV system, hot water collectors, a price change with respect to current, fuel, etc.The heating device can have various heating units that appear expedient to the person skilled in the art, but a heating unit is particularly advantageously designed as a fuel heating block, in particular as a gas heating block, and / or at least as a heat pump. The heat pump can be provided for replacement. However, the fuel heating block is particularly advantageously provided for replacement, as a result of which it is possible to react particularly flexibly to changes to be expected.In a further embodiment, it is proposed that the heating system has a housing, wherein the at least two heating units of the heating device are each arranged at least partially within the housing, as is advantageously a burner of a heating unit configured as a fuel heating block and an inhaus unit of a heating unit configured as a heat pump. Particularly advantageously, a hydraulic unit of the heating system, which is preferably embodied at least partially integrally with a hydraulic unit of the heating unit embodied as a heat pump, is also arranged within the housing, as is advantageously a pump for circulating water within a household, valves, such as pressure compensation valves, compensation containers and / or degasser units, etc.In principle, it is also conceivable for the person skilled in the art to arrange other subunits of the at least two heating units, which are considered expedient, within the housing. An advantageously compact and cost-effective unit can be achieved, namely in particular if the alternative heating unit is also arranged within the housing, either already after a pre-installation, already during delivery, or at least after a replacement and is provided to be arranged within the housing. An installer can carry out the replacement with minimal effort, in particular free of CO2. During the exchange, an emerging space can be used, which was previously occupied by the heating unit of the heating device to be exchanged, such as preferably the heating unit designed as a fuel heating block, or a region provided specifically for this purpose within the housing can be used, such as preferably a region adjoining the fuel heating block.It is furthermore proposed that the heating system has an open-loop and / or closed-loop control unit which is provided to open-loop and / or closed-loop control the alternative heating unit, as a result of which components and costs can be saved. In this case, the open-loop and / or closed-loop control unit is also particularly advantageously arranged within the housing. An provided electronics unit advantageously remains unchanged.Advantageously, a hydraulic unit of the heating system also remains unchanged when one of the heating units of the heating device is deactivated and when the alternative heating unit is activated.In addition, components and installation outlay can be saved if the alternative unit is provided to process a signal of at least one of the heating units, specifically particularly advantageously a signal for controlling a fan.In a further embodiment of the invention, a heating device, in particular a hybrid heating device, is proposed, which has a housing, a heating unit designed as a heat pump and a heating unit designed as a fuel heating block, in particular as a gas heating block, which are each arranged at least partially within the housing. A particularly compact and flexibly usable heating device can be created by a corresponding configuration, namely in particular if one of the heating units is provided for replacement.The heating system according to the invention and the heating device according to the invention should not be limited to the application and embodiment described above. In particular, the heating system according to the invention and the heating device according to the invention can have a number which differs from a number of individual elements, components and units and method steps mentioned herein in order to fulfil a mode of operation described herein.DRAWINGFurther advantages are evident from the following description of the drawings.
