  • the invention relates to a method for adapting a control system for a heater. Also specified are a computer program, a machine-readable storage medium, a control device for a heater and a heater, each of which is provided and set up to carry out the method.
  • the method can be used in particular to compensate for the influences of different exhaust systems on the device performance or heating performance of a heater.
  • Heating devices which each have a conveying device for conveying a fuel-air mixture and a burner for burning the fuel-air mixture.
  • the heat generated by the burner can then be transferred to a liquid circuit of a building in order to heat the building or at least part of it.
  • the heating device and the liquid circuit usually form a heating system for heating the building or part of it.
  • the heat energy emitted by the burner per unit of time is usually referred to as heating output, device output or, if applicable, also generally as the output of the heating device.
  • the heating output of corresponding heating devices is usually only controlled via the drive power of the conveying device. For this purpose, a certain (target) drive power of the conveying device is permanently assigned to a certain (target) heating output.
  • the volume flow of the mixture conveyed by the conveying device does not only depend on the drive power of the conveying device. Rather, it has been found that the pressure losses in the supply air systems and/or in the exhaust systems to which the heaters are usually connected can have a significant influence on the volume flow of the mixture and thus the heating output. In this context, it has been shown in particular that differences in pressure losses that can result from different designs of supply air systems and/or exhaust systems and/or from different ambient conditions can have a significant and therefore considerable influence on the heating output.
  • the pressure loss caused by the exhaust system can, for example, depend significantly on the position of the respective heater on the exhaust system.
  • an unwanted reduction in the burner's output can occur due to comparatively high pressure losses in the exhaust system.
  • a water heating system uses a heated liquid storage tank to ensure a continuous supply of water heated to a desired temperature.
  • a controller varies the speed of a combustion air fan depending on the measured ambient pressure.
  • the object of the invention to provide a method by means of which the problems described in connection with the prior art can be at least partially solved.
  • the method should make it possible to at least partially take into account or compensate for the influences of various supply air systems, exhaust systems and/or ambient conditions on the heating output of a heater.
  • steps a) to c) can be carried out at least once in the order given. Furthermore, steps a) to c) are also repeated (multiple times) or steps a) to c) repeatedly (in the form of a loop) begin with step a). At least parts of steps a) to c), in particular steps a) and b), can be carried out at least partially in parallel or simultaneously.
  • the method can be carried out, for example, during a (first) start-up of the heater in the building, in particular after the heater has been installed in the building.
  • an initial value for the drive power can be stored in the heater control system to determine the initial drive power.
  • the method can be carried out, for example, when the heater is started up several times or even every time, in order to be able to adapt the heater control system to changing environmental conditions, for example.
  • the stored initial value for the drive power or a value for the drive power adjusted in a previous execution of the method to achieve the predefined target heating power can be used to determine the initial drive power.
  • the method advantageously enables performance control to be carried out by means of energy measurement.
  • the performance control can in particular contribute to balancing the influences of various air supply systems and/or exhaust systems and/or ambient conditions (such as ambient temperatures and/or ambient pressures) on the device performance or heating output of a heater.
  • the method (therefore) advantageously enables the influences of various air supply systems, exhaust systems and/or ambient conditions on the heating output of a heater to be at least partially taken into account or even at least partially balanced.
  • the heating device is usually a heating device for a building.
  • the fuel can be, for example, a fossil fuel, such as (liquid and/or natural) gas or (natural) oil.
  • the liquid circuit can be, for example, a water circuit.
  • One or more radiators can be connected to the liquid circuit to heat the building or part of it.
  • a heat exchanger can be provided to transfer heat from the burner to the liquid circuit. This heat exchanger can be arranged between the burner and the liquid circuit.
  • the heat exchanger can be assigned to the burner or formed within the heating device and/or in the area of the burner.
  • the control can be implemented, for example, by means of a control device of the heating device.
  • the control such as a (computer) program for controlling the heating device, can be implemented in the control device.
  • the heating device can preferably be a gas heating device.
  • this particularly relates to a heating device which is designed to burn one or more (gaseous) fossil fuels such as liquid gas and/or natural gas, possibly with the supply of ambient air from a building or the surrounding area, in order to generate energy for heating a water circuit for heating the building or part thereof.
  • the heating device can be a so-called gas condensing boiler.
  • the heating device generally has at least one burner and at least one conveying device, such as a fan, which can convey a mixture of fuel (gas) and combustion air (through a mixture channel of the heating device) to the burner.
  • Exhaust gases resulting from combustion can be discharged through an (internal) exhaust pipe of the heater to a (possibly shared or multiple) Exhaust system (of the building).
  • Several heaters can be connected to this (common or multiple-use) exhaust system.
  • Exhaust gases produced by combustion can (thus) be discharged from the burner, for example, via an exhaust system.
  • the exhaust system can comprise an exhaust pipe (internal to the heater) and at least part of an exhaust system (external to the heater) (of the building).
  • the exhaust system can discharge into the environment around the building via at least one chimney.

  • the influences of various exhaust systems and/or exhaust paths on the device performance or heating performance of the heater can be advantageously taken into account and/or balanced out as far as possible.
  • Air that can be used for combustion can, for example, be supplied to a mixing point for mixing fuel and air to form the fuel-air mixture (and thus to the burner) via a supply air system.

  • the heater can be connected to various supply air systems.
  • a supply air path extending from the heater to the environment can be different (depending on the supply air system), in particular different dimensions, for example different lengths.
  • the method described here can be used to take into account the influences of various The effects of supply air systems and/or supply air routes on the device performance or heating output of the heater should be taken into account in an advantageous manner and/or balanced out as far as possible.
  • the supply air can be mixed with fuel in a predeterminable and/or as constant as possible mixing ratio.
  • the mixing ratio can, for example, be fixed or adjustable (manually or by an installer or skilled tradesman). After the mixing ratio has been set, it is usually kept as constant as possible (until it is adjusted again if necessary). A deviation in the delivery volume of the delivery device therefore usually (in particular pneumatically and/or electronically) also has an (immediate) effect on the amount of fuel supplied and thus the heating output.
  • the mixing ratio can be adjusted and/or kept as constant as possible via a so-called fuel-air connection of the heater, in particular by means of a gas valve on the heater.
  • the building can generally be a residential building and/or a commercial building.
