Method for operating a heating device
Technical Field
The invention relates to a method for operating a heating system, in which method a burner device belonging to the heating system is operated at its start-up with either a first start-up load or a second start-up load.
Background
A method for operating a heating system of the type mentioned at the outset is known from the document DE 200 10 092 U1. There, a gas burner is described which is started with a starting load, the level of which is adjustable.
Disclosure of Invention
The object of the invention is to improve a method of the type mentioned at the outset. In particular, a method for operating a heating device should be realized which ensures a high Shu Xing degrees for the user of the heating device and at the same time avoids frequent cycles (Takt).
This object is achieved by a method for operating a heating system of the type mentioned at the outset, in which a first measured value in the form of the volume flow of a heating medium located in the heating system and a second measured value in the form of the temperature of the heating medium are measured before the burner arrangement is started, in which the first measured value is entered by a computing unit of the heating system into a previously determined linear equation which accounts for the dependence of the temperature on the volume flow and from which a temperature limit value is calculated before the burner arrangement is started, in which a second measured value is compared by the computing unit of the heating system with the temperature limit value before the burner arrangement is started, in which the burner arrangement is operated with a first start-up load at its start-up if the second measured value is greater than the temperature limit value, and with a second start-up load at its start-up if the second measured value is smaller than the temperature limit value.
In other words, the advantage of the solution according to the invention is therefore that the starting load of the burner arrangement of the heating device is determined by means of the measured value pairs of the temperature and the volume flow and the linear equation. The heating device can thus automatically select an adapted starting load for the current operating mode. Thereby, the heating device may bring the heating medium, e.g. water, to the desired temperature more quickly. This is comfortable for the user of the heating installation, since he does not have to wait for a long time for water of a suitable temperature and also protect the heating installation, since the heating installation therefore does not have to be switched frequently between different load modes.
