The Matlab version of SIMDEUM models both total water demand per tap and hot water demand. The hot water demand is determined by 1) temperature of the water at tap (which is a feature of the end use, e.g. showering with 40 °C, bath 40 °C, dish wahsing at kitchen tap with 55 °C); 2) the temperarure of the cold water coming into the house (can vary over the season from 5 to 25 °C in the Netherlands); 3) temperature of the hot water (at hot water boiler typically 60-85 °C, but also consider heat loss between boiler and tap).
Modelling hot water demand allows for better modelling and design of premise plumbing systems
