The article presents a method for determining the maximum hourly hot water consumption with specified probability of occurrence taking into account the number of inhabitants in multi-family residential buildings. It was assumed that the maximum hourly water demand per single resident of the building is a random variable with a normal distribution with the expected value of –qj max and the standard deviation of S–qj max . Then, based on these assumptions, the parameters of the distribution of the maximum hourly hot water demand were determined. For this purpose, the results of water consumption measurements by residents of seven residential buildings located in several housing estates in Szczecin were used. Knowledge of the distribution parameters allows for determining the variability of the unit consumption value depending on the probability. Using this information, the average unit water demand was calculated for probabilities of 90%, 95%, 99%, and 99.9%, along with lower values depending on the number of building inhabitants. The results obtained are presented in a graph.
