Heating apparatus

Claim 1

In a method of operating a heating system in which a heating fluid for the heating of at least one room is brought to an advance heating temperature and has a heating capability which can be represented by a value T V before being used to heat said room and a temperature T R representing the heating effect in terms of room temperature and resulting from use of the heating fluid is controlled in dependence upon an external temperature T A in accordance with a heating curve, the improvement which comprises optimizing said heating curve by approximating the heating curve with a heating curve equation including at least one parameter, automatically determining a number of values for said parameter in time-spaced succession with each value being established by a statistical regression method from values at least in part determined by instantaneous values of T A , T V and T R , substituting the parameter thus determined in said equation to thereby increase the precision of the heating curve with which the temperature of the room is controlled, and storing values determined by said instantaneous values, averaging the stored values, and determining the values for said parameter from the averaged stored values, the values which are stored and averaged being values y=T V -T R and u=T R -T A representing temperature differences, at least for initial optimization of said heating curve, the room temperature being controlled from a predetermined starting heating curve and thereafter, the room temperature being controlled by a previously optimized heating curve.
