This article studies some of the statistical properties of domestic hot water (DHW) consumption. The study is based on experimental data obtained for a group of households, over a 1 year period. To describe the consumptions, we consider three representative statistical properties of the drain sequence associated to each household: i) the distribution of the magnitude of the drains, ii) a daily pattern of the start times of consumptions, iii) the time between two successive drains. A remarkable outcome of the study is that the time between two successive drains follows a bimodal Weibull distribution. This opens perspectives for piloting applications.
