To investigate the daily distribution of hot water during different periods of the year, the measured average hourly hot water use for five months 2006 is shown in Figure 5. The curves coincide rather well, showing the same, typical variations. This implies that the individual behaviour is similar all year around. There is a difference between winter time and summer time found in Figure 4. In the winter months, January and February, the morning peaks appear somewhat later, especially in weekdays. According to the residential company, summer time is however accounted for in the measurements.

Figure 5. The figure shows the daily distribution of hot water use for different months. In figure a) an average
weekday is shown and in b) an average weekend day is found.
