District Heating

Reykjavík district heating

District heating in Reykjavik started on a small scale in 1930. In 1933, about 3% of Reykjavik's population were connected to Reykjavik District Heating. At that time, coal was mainly used for heating, and dark clouds of smoke were commonly seen over Reykjavik. Moreover, pipelines were laid to nearby municipalities, which are now supplied with geothermal water by the district heating in Reykjavik. The use of geothermal water in Reykjavik for space heating instead of fossil fuels reduces air pollution. Today, almost all houses in the area are connected to the district heating system.


Reykjavik City

Geothermal energy is a renewable source of energy which can improve the quality of life of people in a sustainable way. One of the best examples of this is the city of Reykjavík which used to be covered with plumes of smoke due to the burning of fossil fuels. Today, the inhabitants of Reykjavík enjoy an environmentally friendly and competitive heating system utilising energy provided by Earth itself. 

The district heating in Reykjavik serves 57% of the population of Iceland with geothermal water, and was the world’s largest municipal geothermal heating service. The installed power is now over 830 MW with energy provided by four low temperature geothermal fields in Reykir, Reykjahlið, Laugarnes and Elliðaár and by cogeneration at the Nesjavellir and Hellisheiði high temperature geothermal area, located about 30 km east of the city.

Verkis has designed the major part of the geothermal district heating system owned and operated by Reykjavík Energy, including most of the pumping stations, storage tanks, the 27 km long Nesjavellir pipeline and other major transmission pipelines such as the Reykir pipelines, and the distribution network in Reykjavík, Kópavogur and Garðabær. In recent years, the oldest part of the network in Reykjavík (over 40 years old) has been refurbished.
