- One branching off Contains supply line to the gas nozzle plate of the second burner stage another, non-modulating solenoid valve. By doing this further If the solenoid valve is opened or closed, the gas solenoid valve acts either to both burner stages or only to one burner stage.
- From DE 196 23 239 is a two-stage gas burner for use in houses or Apartments with a first modulating level and a second constant Stage known.
- the second stage is parallel to the first via a solenoid valve Stage switched and can be switched on and off.
- EP 0 818 655 discloses an apparatus for the controlled reduction of one Gas flow, which is a burner nozzle of a gas-operated cooking or Baking device is supplied via a gas supply line.
- the gas supply line is in one Number of partial gas lines branched, which are connected in parallel to each other and via which partial gas flows can be fed to the burner nozzle.
- the device further includes control elements with switching elements for optional input and Switching off the respective partial gas flows and throttle elements for throttling the respective partial gas flows.
- the object of the invention is to provide a heater by means of which a rapid heating-up time can be realized, which is an exact and reliable control of the heating output of the at least two burner stages also in Range of a heating output greater than the normal output and which is also inexpensive to manufacture.
- the heater according to the invention is used in particular for campers, caravans etc. used. It is with a heat exchanger, with at least one Burner device and at least two burner stages and a valve for Provide control of the fuel supply to a pilot burner.
- the fuel the burner device via a fuel supply line from the valve preferably a fixed throttle and by means of an adjustable throttle element in Depending on the heat demand of the room to be heated.
- the valve has a bypass valve with a Actuator on.
- the bypass valve is in a bypass to the Fuel supply line upstream of the at least two burner stages arranged, being larger than normal in the event of heating power being required Power the fuel supply to the burner stages by opening the bypass valve is increased by means of the actuating device.
- the adjustable Throttle element is in the fuel supply line before branching, however outside the bypass and after a branch from the Fuel supply line arranged to the pilot burner.
- turbo heating mode The increase in the fuel supply when the power requirement exceeds the normal power is also referred to as turbo heating mode.
- normal power the power which the heat exchanger of the heater can be transferred by free convection without a fan is switched on.
- This maximum by free convection through the Heat exchanger transferable performance represents a 100% performance which the Sum of those generated by the burner stages and by the pilot burner Total performance includes.
- this greater output greater than 100% power
- a major advantage of the heater according to the invention is, among other things in that the burner device by means of a single bypass valve including the at least two burner stages so controllable or with one corresponding amount of fuel can be acted on, that even when the Heater in turbo heating mode has a higher output than the 100% output the room to be heated can be delivered and also in this Power range an exact regulation of the heating power is possible.
- the regulation the at least two burner stages do not take place by adding or Switching off a single burner stage to achieve a higher output than the 100% performance, as is the case in the prior art, but by Operation and control of all burner levels in the entire performance range including performance in turbo heating mode.
- the burner device is preferably designed with two burners, the two burners form a first and a second burner stage. About the Fuel supply line, the two burners are supplied with fuel. If the need for heating output greater than the normal output compared to the 100% output requires higher fuel supply, the bypass valve is opened so that the first and second burner stages burn so much fuel that one Power greater than the normal power can be achieved, even then one Room temperature-based control of the heating output in turbo heating mode he follows.

- the heat exchanger is therefore preferably dimensioned such that it is in is able to achieve normal power, i.e. the 100% performance transfer. If a heating output greater than the normal output is to be transferred, it is therefore necessary that the blower be in operation.
- the actuator is coupled to the blower, it is thus ensured that the Bypass valve only opens and the two burner stages only then additional Supports fuel when the blower is operating. This makes it possible for Heater even with turbo heating a smaller sized heat exchanger provide and still ensure that this heat exchanger in Turbo heating mode is not overloaded.
- the fan and / or the actuating device are preferably manual actuatable. However, it is also possible that the blower and / or the Actuator automatically based on a heat demand signal can be operated.
