Large-scale Norwegian solar heating with a unique assembly

Large-scale solar heating is an important energy resource for counteracting part of the heavily increasing energy prices and the uncertainties related to the future energy supply. Solar heating is important in Norway as well. Investing in solar energy represents new ways of thinking among the Norwegians. However, energy calculations show that solar collectors could become a profitable investment, also in the Scandinavian countries.

People in Lillestrøm take the climate challenge seriously. Here, approximately 15,000 households are heated by the big-gest Norwegian large-scale plant in Akershus EnergyPark. In 2011, isoplus started its cooperation with L&H Rørbyg and SUNMARK in order to provide a complete system of 13,000 m2 of solar collectors, which were put up in the fields near Lillestrøm.

isoplus is the company behind the delivery of joints, alarm system and 1.5 km of continuously produced, pre-designed pipes, which L&H Rørbyg subsequently re-designed as solar collector pipes.

SUNMARK in Svendborg converted the solar collector pipes into a complete assembly and transported them to their final destination at Akershus Energi in Lillestrøm. Here, the solar collectors were connected to the district heating net-work by means of 190 distributor branches.

The result is a unique assembly, while isoplus also assisted with static calculations, which are an essential prerequisite of guaranteeing the technical lifetime of the solar system.
