Title: Arrangement of two series-connected or parallel-connected thermal elements
Inventor: ORTLINGHAUS ULRICH DIPL ING
IPC: F23N5/10
Filed: 1981-02-14
Abstract: The present invention relates to an arrangement of two thermal elements which are connected to one another in series or parallel and act jointly on an electromagnet of a thermoelectric ignition fuse. In the case of series connection, dissimilar poles of thermal elements are connected to one another, and in the case of parallel connection, like poles are connected to one another. One thermal element is externally heated by an electrical heating resistor, while the other is allocated to the ignition burner of the thermoelectric ignition fuse. As a result of this arrangement, it is possible to monitor the thermoelectric ignition fuse during pauses in operation of a burner of a heat source, via that thermal element which is allocated to the ignition burner, while a thermal flow simulation can be carried out via externally heated thermal elements during pauses in operation of the heat source, which simulation is interrupted immediately if a heat requirement command is issued to the heat source. The main field of application of the invention is preferably gas-heated water heaters.
