Wherever district heating is available, it is an interesting alternative to traditional heating systems fueled by oil or gas. This is not only the case in residential homes but also applies for all areas where heating and domestic hot water production is needed.
Danfoss delivered our substation type FSD2550 H2 ECL 300 for the reproduction of the legendary Huxing-Ting-Teahouse from the Yu-Garden in Shanghai for this project in Hamburg. The substation transfers a capacity of 300 kW on 2 heating circuits and is a domestic hot water system comprising a 500 liter storage volume.
The energy company Vattenfall delivers the district heating with a flow temperature of 136 °C and 25 bar. Thanks to the customized substation with its optimal dimensioning, weather compensation and high-quality automatic controls a maximum spread of 101 K is achieved. As a result the return temperature is only 35 °C making the network and system operation very economic.
