østerild-fjernvarme_20130218-DSC_4981-Edit of 5.5 million kWh per year Østerild District Heating Plant supplies 250 users in the village of Østerild with hot water. The plant is 100% consumer owned and run by a board elected by the consumers. The daily operations of the plant are taken care of by a manager. Within the supply area of the plant connection to the grid is mandatory.
Østerild District Heating has joined forces with two other minor district heating plants in the nearby villages of Frøstrup and Vesløs. Together they buy solid fuel in the form of wood briquettes from a local furniture manufacturer and tackle rising expenditure on salaries by taking turns keeping the weekend watch at the three plants.

The Wood Briquette Boiler

østerild-fjernvarme_20130218-DSC_4970-Edit The plant in Østerild is primarily fired by wooden briquettes purchased from the furniture manufacturer NJA Furniture in the nearby village of Nors. The briquettes are a waste product from the production of wooden furniture and consist of sawdust pressurized into briquettes. Moisture content in the briquettes is very low, about 8-10%, which adds considerably to the expected lifespan of the boiler compared to boilers using wet fuel like wood chips.
Each year the plant receives around 1600 tons of briquettes. The storage capacity is for between 700 and 1000 cubic meters of briquettes, which is enough for three to four months. The production is fully automated and the boiler is equipped with sensors that register when more fuel is required. In the storage room a crane lifts the briquettes and dumps them in a spiral conveyor that feeds the fuel into the boiler.
The heating plant also disposes of an oil fired boiler for emergencies.

Cleaning the Flue Gas

In 2009 Østerild Heating Plant invested in a new flue gas cleaning system that removes particles from the flue gas before it is let through the chimney and out into the open. The flue gas is filtered through 150 filter bags suspended inside the flue gas cleaner. Ash and particles gather at the floor of the cleaning system from where it is collected and destroyed.

Remote Reading of Meters

østerild-fjernvarme_20130218-DSC_4977-Edit In 2006 the district heating plant in Østerild replaced all existing district heating meters with new remote controlled units as a service to the consumers. Electronic controllers enable remote monitoring and control of the district heating system and allow the plant to conduct remote controlled readings of meters, saving the consumers the trouble of reading the meters themselves. As a bonus the plant now has a better tool for keeping an eye on individual installations and detect excess consumption as a result of for example leakage or defect valves. As an extra service the plant conducts a yearly service check on all installations which also allows for a talk about saving energy and making energy renovations.


Each year district heating plants in Denmark submit their price lists to the Danish Energy Regulatory Authority. According to the price list of December 2012, district heating from Østerild District Heating costs DKK 563  per MWh VAT included. This means an annual cost of DKK 14.531 for heating in a standard flat of 75 m2 consuming 15 MWh per year, and an annual cost of DKK 17.994 for heating in a standard single-family house consuming 18.1 MWh per year.
The above mentioned prices are standard prices and in order to calculate the actual price for heating it is necessary to consider the actual heat consumption of a given family and the fixed costs of for example subscription.
