Changes in the Heating Load of Domestic Hot Water and its Impact on the Design of the District Heating Network
Authors: ,
Abstract: The article gives an overview of the changes in the field of domestic hot water (DHW) consumption. In Eastern Europe instantaneous water heaters are widely used for DHW heating. Over the past 20-25 years there has been a significant change in DHW consumption in Eastern Europe and Estonia. The changes have been so great that new dimensioning methodology is needed. This necessity has also been stated by Dutch investigators. The developed methodology allows to reduce the capacity of instantaneous DHW heaters in residential, educational and public buildings by up to two times. The new calculation methodology of DHW heaters can significantly reduce duct size in tree-shaped district heating (DH) networks, the station power and maintenance costs.
