Statistics about District Heating

Households Supplied by District Heating, (2014-2017 and 2010-2017) 

In 1979 Denmark passed its first heating supply law, namely The Heat Supply Act from 1979 (revised extensively in 1990, 2000 and 2005). The act has been leading to an increase in the usage of distric heating, which is now the dominant source of heat in Danish households. Furhermore, the act is containing regulations regarding the implementation and content of heat planning in the country, which is managed at municipal level.

The development shows district heating dominates as a heating solution for households in Denmark. Today, 64.4 percent of Danish households are connected to the district heating system, corresponding to a total number of 1.713.449 households. The following tables summarizes the development of district heating in the periodes of 2014-2017 and 2010-2017. In order for the green transition to be a success, the heating sector plays an important role, in achiving Denmark’s ambition of being independent of fossil fuels by 2050.


Table 1 shows the actual number of households connected to district heating from 2014-2017. Table 1 also show the total percentage of households supplied with district heating.

Table 2 shows the development of Danish households connected to district heating from 2010-2017. The following table shows a increase in total household connected to district heating from 2010-2017.

Residential Heating in Denmark, (1981-2016)

District heating is the most important heating source in the residential heating. District heating provides 64.4 percent of all Danish households in the total heat supply. The figure below shows the development of residential heating type from 1981 to 2016. The figure shows that the demand for fossil fuels has continuously decreased over the period. One of the key elements in the Energy Agreement from 2012, was to reduce individual heating using oil and gas in buildings, and to promote renewable alternatives. Furthermore, to reduce oil and gas in buildings was one of the intiatives in the Energy Agreement from 2012, a total ban on installing oil-fired and gas-fired boilers in new buildings from 2013 onwards.

District Heating Production by Fuel, (1990-2016) percentage distribution

The district heating sector is large and heat is the third-largest energy source in total consumption. The following figure shows the production of district heating has shifted from being largely based on fossil fuels to a clear dominance of renewable energy from 1990-2016. This shift is an important goal for the Danish, ambitious energy policy and environmental targets.
