Abstract: The effects of new heat pump and solar collector capacity in an existing district heating system are investigated by using Helsinki as a case study. Existing heat supply consists of combined heat and power plants, boilers and large-scale heat pumps. Also, the potential benefit of low distribution temperatures is evaluated. Both an outdoor temperature dependent supply temperature between 80 and 110 °C and a constant supply temperature of 65 °C are considered for distribution.
