The Skogarorka Ecological Remote Heating System

03 About Skogarorka

Skogarorka ltd. runs the wood-chip district heating in Hallormsstadur, eastern Iceland. It has been equipped with Control2Net and RHINO PLC-based hardware to communicate via the existing power lines with all building it heats up.

The wood-chip boiler uses timber from the surrounding forests to provide heat and hot water in a self-sufficient and eco-friendly way. Considering the growing forest area in Iceland this form of energy consumption is a real alternative in cold areas, i.e. areas without geothermal energy.


PURE ENERGY
Burning wood chips is a CO2 neutral energy source and therefore an eco-friendly choice. The amount of carbon dioxide emitted during the combustion of the chips is similar to the amount of CO2 emitted if the tree was to let die and rot.

WOODCHIP DISTRICT HEATING
The wood chip district heating is the first of its kind in Iceland. In Scandinavia and other parts of Europe, though, where firewood is available nearby, this kind of house heating has become very common.

HALLORMSSTADUR
The forest in Hallormsstadur is the most famous forest in Iceland and features the country´s highest trees. Therefore it suits that firewood from it is used to heat the community inside it.  Geothermal heat is not available in this area.
