Verfahren und Vorrichtung zur Ermittlung des Wärmebedarfs eines Heizungssystems

摘要

The external temperature is measured by a sensor (38) in relation to time by means of a clock (46) and the characteristic quantity of energy expended by the heat source (26) on the heating system (12) is measured by a meter (42). The nominal heat requirement is calculated from the measurements. Measurements are taken at least until the ratio of calculated maximum nominal heat requirement, in relation to a calculated minimum nominal heat requirement is greater than a pre-determined figure which is greater than 1.
