  • the heating water is usually between 30 and 60 °C in the flow, higher temperatures can also occur, for example up to 90 °C - a lower temperature in the return.
  • a method for providing heating water may be relevant here, namely for a heating system using heating water from the primary heating flow.
  • heating circuit can refer to a single heating circuit or connected heating circuits, mixed or unmixed.
  • the “primary heating flow” is understood to mean the flow of the heating water, which leads to a valve that can allow, throttle or stop the heating water in a secondary heating circuit.
  • the primary heating flow can be the line, i.e. a heating flow from a central heater for heating water, which then leads to the various apartments in an apartment building. Each apartment in the apartment building is transferred to a secondary heating flow.
  • the secondary heating flow is the flow for each individual residential unit or at least for a subset of the residential units supplied by the line.
  • the heating water passes through radiators, such as radiators or underfloor heating pipes. The heating water then runs back from the secondary heating circuit and is now to be understood as a secondary circulation of heating water. After passing through a valve, the secondary return of heating water is returned to the line, namely the return of the line, and therefore into the primary return of heating water.

  • electric servomotors have proven to be particularly advantageous and robust.
  • the actuator then in turn sets a valve to an opening degree.
  • the degree of opening must be more than zero to allow flow, it can be up to 100%.
  • valve is set to an opening degree results in a flow of heating water through the heat exchanger system. Therefore, depending on the degree of opening, more or less much heating water with the heat energy it contains is carried into a branch (namely the heat exchanger system). There, the heating water transfers heat energy to the domestic hot water (specifically: into the drinking water, to produce the domestic hot water).

  • the flow through the secondary heating system is completely prevented using a priority circuit, and the heating water from the primary heating flow is made completely available for the heat exchanger system.
  • the flow rate of the heating water is controlled by the heat exchanger system.
  • the device parts can be designed to be thermally separated: the sensor on the drinking water line, i.e. in the sanitary system, is not influenced by the heating system and its valve, and vice versa analogously.
  • the domestic hot water can be heated by exchanging heat energy from the throughput of the heating water.
  • a heat exchanger can be used for this purpose.
  • a line of the sanitary system is routed through the heat exchanger, namely the line to the tap; on the other hand, a line of the heating system, preferably in such a way that the heating water is branched off from the secondary heating circuit and instead of passing through the secondary heating price, it now passes through a branch which leads through the heat exchanger.
  • the secondary heating circuit is throttled or stopped in the forward or return flow by means of the valve, then at the same time when the valve is opened or as a result of a hydraulic effect, the branch can flow through the heat exchanger instead, whereby the heating water in the heat exchanger absorbs the drinking water that flows there preferably in the opposite direction Domestic hot water temperature heated.

  • the home station can, for example, be installed instead of an existing gas boiler with a wall-mounted housing, which supports the energy-efficient renovation of existing buildings.
  • a “housing” of a home station is in particular a flat spatial unit, for example made of sheet metal, with two or three or especially four sheets running around the edge of the housing and preferably with a larger rectangular sheet metal for the back of the housing.
  • the back can - just like the edge parts - have openings; for example, prefabricated holes on the back are useful for hanging the home station on the building wall or for leading out cables such as power lines.
  • a home station can be understood in an (artificially expanded) sense when the transfer fittings and piping and valves are arranged in a spatial accumulation such as a wall niche.
  • a home station is also referred to in the market as a decentralized fresh water station.
  • a heat exchanger and at such a station several connections are arranged, often next to each other on one side of the housing, in particular an inlet for drinking water, an outlet for drinking hot water, a drinking hot water circulation, a connection for the primary heating flow, one Connection for the primary heating return, one connection for the secondary heating flow (i.e. into the apartment) and one connection for the secondary heating return (i.e. out of the apartment), if necessary additional heating circuits, back into the station and continue from there to be routed primarily into the heating return).
  • a heat exchanger especially a countercurrent heat exchanger, can be provided in the station. This means the installer has as few connections as possible and the thermal effects can be taken into account as best as possible within the station.
  • a second heat exchanger can also be installed in the home station as a system separation of the primary/secondary heating network to supply the heating heat in the apartment.
  • Any proportional or non-proportional assignment of the desired degree of opening in the heating system can be provided in the control system depending on the requested flow in the sanitary system and the detected flow in the heating system.

  • the control system can control the actuator so that it moves a valve insert in the valve to a specified valve position.
  • the level of domestic hot water requirements and the associated valve position would be a pair of values.
  • the valve insert preferably closes a return line in the heating system.
  • the primary heating flow i.e. the hot water
  • the primary heating flow is routed to a secondary heating flow. This will often happen in a home station, with the home station having a dedicated connection for the primary heating flow and a dedicated connection for the secondary heating flow.
  • the secondary heating flow leads to the radiators within the room, for example the apartment or office.
  • There the heating circuit releases its heat and returns to the home station as a secondary heating return.
  • the secondary heating return will also usually have a permanent connection to the home station.
  • the secondary heating return is then led into the primary heating return, i.e. back towards the line and thus, for example, back to the basement to the heating system.
  • valve insert or the valve in general, is intended to partially or completely throttle the secondary heating circuit, i.e. the heating system within the room, then there are several possibilities. If this is to happen within the home station, then a valve either in the flow or in the return line is ideal.
  • valve insert can be moved into a valve position in order to control the secondary heating circuit independently of a demand for domestic hot water.
  • the invention considers it to be advantageous if the intervention in the circuit takes place in the return flow.
  • the secondary heating return is connected to the valve body within the apartment stations.
  • the valve insert can throttle or stop the flow, so that the throughput through the secondary heating circuit is throttled or stopped.
  • control system moves the valve core for the secondary flow in the heating system to a valve position on each request, where one of the valve positions should be a closed position, while one of the valve positions should be a fully open position, then the control system is able to control the secondary flow in the heating system to be operated whenever there is a demand for domestic hot water in the heat exchanger system.
  • the invention is based on the knowledge that the radiators have thermal inertia. They are flowed through most of the day, provided the temperatures require it, and heat themselves and, for example, the masonry or the floor around them, as well as the room air and thus all room surfaces via convection. Drinking hot water, on the other hand, is only tapped in short, discrete periods of time. Therefore, the control system can easily throttle or stop the secondary flow in the heating system as long as domestic hot water is being drawn. In other words: domestic hot water tapping is a priority circuit. The available energy, which comes from the primary heating flow, is then used partly or completely to provide domestic hot water. Even if, for example, the tap is drawn for half an hour or an entire hour, this will generally not cause the heating system to cool down unpleasantly.
  • the control system may be configured to move the valve insert for the secondary return in the heating system to a fully closed position.
  • control system moves exactly one valve insert and the valve insert adjusts both, i.e. the return flow in the heating system and the throughput of heating water in the heat exchanger system for heating the drinking water.
  • the kinematics prove to be particularly simple, and the available installation space, which is naturally very limited in a home station, only has to be loaded with one actuator, i.e. only with exactly one actuator.
  • One actuator can move the valve insert, for example move or rotate it, and use this kinematic adjustment to accurately adjust both the throughput in the heating system and the throughput in the heat exchanger system.
  • the actuator can advantageously stand in axial parallelism or coaxially with a valve insert and exert a rotary movement on the valve insert.
  • the very limited installation space available in a home station offers a very easily controllable control option that can be controlled with manageable torques by rotating a valve insert or, more specifically, disks within a valve insert.
  • the actuator is coaxial, a shaft can be guided along the valve body, which runs from the actuator to the disks of the valve insert; With an axially parallel arrangement, the actuator can be connected via a gear to a shaft which leads to the valve insert. It is proposed that the valve insert, when activated by the actuator, controls a directional control valve between a first and a second inlet and a common outlet.
  • the valve body has a first and a second inlet.
  • the first inlet is integrated into the heat exchanger system;
  • the second inlet is integrated into the heating system, i.e. the secondary heating system.

  • the first inlet can come from the heat exchanger system, and the second inlet can come from the secondary heating system, while the common outlet leads to the primary heating system.
  • valve intervenes in a secondary heating return and throttles or interrupts it in order to divert available, incoming heating water from the primary heating flow and thus enable the throughput of heating water into the heat exchanger system for heating drinking water.
  • valve connects a first inlet which is transverse to an axis with an outlet which is transverse to the axis
  • the valve can have a longitudinal extension, or an axis, especially one around which an actuator shaft rotates, or around which valve disks rotate.
