ABSTRACT
The effective consumption time of hot water in multi-apartment buildings depends on the daily activities of residents, their number, habits and overall size of the system. On the basis of the aggregated data from 8 multi-apartments building, with between 36 and 291 draw-off points each, the effective consumption time during the day was determined. The data was then calculated to show the daily consumption per draw-off point. The least squares method was applied to the assumed consumption model to determine the total number of consumption hours per day.
