Benefits of technology

The objective of this patent is to create a heating device that is more cost-effective and service-friendly.

Problems solved by technology

Due to defects or wear, leakages can occur at the fuel valve or at another location of the fuel supply such that fuel leaks.
Therefrom high expenditures and high costs result from such a preventive exchange involved with a maintenance service.
In case leakage occurs upstream or downstream from the fuel valve (e.g. defective sealings), this leakage would not be remedied by means of a preventive exchange of the fuel valve.

Embodiment Construction

[0038]In FIG. 1 a block diagram of an embodiment of a heating device 10 is illustrated. The heating device 10 comprises an outer housing 11 surrounding an installation space 12. The outer housing 11 separates the installation space 12 from an outer environment 13 at the installation location of the outer housing 11 according to the example at least not in a complete gas-tight manner. A gas exchange between the outer environment 13 and the installation space 12 is thus possible.

[0039]A burner unit 14 is arranged in the installation space 12. The burner unit 14 has burner housing 15 in which a combustion chamber 16 is located. A mixture of a fuel B and an oxidizing agent, according to the example air L, is combusted in the combustion chamber 16 by means of a burner 17, whereby a hot exhaust stream is created. The hot exhaust stream flows along at least one and according to the example two heat exchanger units 18, 19 connected in series according to the example. The first heat exchange...

Abstract

A heating device as well as a method for the operation thereof. The heating device has an outer housing that surrounds an installation space. The components of heating device are arranged inside or on the outer housing, particularly a burner unit, a fan, a fuel valve and as an option a circulation pump. At least one of these units comprises at least one electrical and / or electronic component. On one or more of the anyway present electrical and / or electronic components at least one gas sensor is arranged on the outer housing and / or inside the installation space, particularly on a support or a circuit board of the respective electrical and / or electronic component. The at least one gas sensor is configured to create a sensor signal that describes the presence and / or concentration of at least one gas component in the atmosphere. Based thereon leakages, faults, undesired backflow, etc. can be determined. Thereupon a respective measure can be initiated, e.g. the output of a warning message and / or suction of the atmosphere by means of fan.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. § 119 to the following German Patent Application No. 10 2021 105 962.3, filed on Mar. 11, 2021, the entire contents of which are incorporated herein by reference thereto.TECHNICAL FIELD[0002]The invention refers to a heating device, e.g. for heating of a heat transfer medium, particularly water. The heating device can be configured to heat a building or a part of a building and / or to provide warm water by means of the heat transfer medium. The warm water can be provided for a kitchen, a bathroom, etc. in a building or part of a building.BACKGROUND[0003]A heating device that comprises a burner unit and a fan is known from DE 10 2006 004 506 A1. The fan is arranged downstream behind the burner unit. In an exhaust channel a mass flow sensor can be inserted, e.g. to detect the hydrogen mass flow or the carbon dioxide mass flow. On the basis of the sensor signal the control for the composition o...
