Energy efficiency of domestic hot water distribution system
The aim of paper is to analyze the thermal losses of domestic hot water (DHW) distribution system. There were used calculation methods by valid EN standard for energy performance of building. The analysis of energy performance was done for multi-dwelling house with 5 floors with total number of flats 32 (two-room and three-room flats on the 2nd to 5th floors). There are total 86 residents in the house and the average consumption of DHW is at 40 litres per person and day.
