Abstract: This invention relates to a heater. A combustion air blower feeds combustion air to a burner device. The burner device burns a gas-air mixture from the combustion air and a fuel and serves for heating air. A circulating air blower discharges heated air from the heater. A control device acts on at least one component of the heater, wherein a night mode parameter set associated with an operation of the heater in a night mode and a default parameter set are stored in a data storage device. After an activation of the night mode, the control device accesses the night mode parameter set and uses the same for acting on the component. The night mode parameter set effects a reduction of background noise generated by the heater.

Abstract: The invention relates to a method of manufacturing a heating device (1) which has a fan (3) located behind a grid (2) in an interior (10). The fan (3) is mounted in the interior (10), and the grid (2) is mounted as a part of the heating device (1). The speed of the fan (3) is determined in a contactless manner by evaluating a reflection behavior of the fan (3) in that a light signal (50) is emitted through a recess (20) in the grid (2) in the direction of the fan (3), and/or is received through a recess (20) in the grid (2) from the direction of the fan (3). Furthermore, the invention relates to a heating device (1).

Abstract: The invention relates to a valve device (1) having a pressure regulator (3) for a flowing gas and a housing (4). The pressure regulator (3) includes a diaphragm (31), a spring (34), a control actuator (32), and a control seat (33). The control actuator (32) includes a plate-like portion (32) and a rod-like portion (32?) adjacent to one side of the plate-like portion (32), the control seat (31) encompassing the rod-like portion (32?) of the control actuator (32). The diaphragm (31) and the control actuator (32) are mechanically coupled to each other such that an axial movement of the control actuator (32) moves the diaphragm (31). In addition, the spring (34) and the control actuator (32) are mechanically coupled to each other. The control seat (33) limits a movement of the control actuator (32). In one state, the control seat (33) and the control actuator (32) prevent the gas from flowing. The control seat (33) is configured as a ring arranged in a recess (40) of the housing (4).

Abstract: A pressure regulator has a housing with an inlet, an outlet and a valve seat. A regulator sleeve is arranged within the housing and defines a flow channel from an upstream end adapted for cooperating with the valve seat towards a downstream end associated with the outlet. A spring biases the regulator sleeve towards the outlet. The downstream end of the flow channel tapers outwardly.
