What is district heating in Denmark?

District heating plants in Denmark produce heat and electricity for 1.7 million households, 64% of all Danish homes. Some 40% of the energy mix in the country’s district heating system is, however, fossil fuels, mainly coal and gas. With a national goal to be fossil free by 2050, something has to change.

How do they heat homes in Denmark?

Individual heating is typically from oil boilers, individual heat pumps, or biomass boilers. Previously, most heating in Denmark was from individual supplies such as oil boilers, but due to the expansion of the collective heat supply, individual heat supply is now mainly dominant in rural areas and small towns.

How does a district heating system work?

CHP boilers take the heat from cooling the engine during electricity generation which is then recycled and used to heat buildings. Other district heating systems capture free waste heat from train tunnels, helping to subsidise heating bills for people connected to the network.

What is district heating system?

District heating is a heat distribution system that sends heat to multiple buildings from a central plant that generates heat and sometimes power as well.

What is district heating network?

District heating (also known as heat networks or teleheating) is a system for distributing heat generated in a centralized location through a system of insulated pipes for residential and commercial heating requirements such as space heating and water heating.

What is district energy system?

A district energy system’s central energy plant either generates or extracts heat from a renewable source, such as wood waste, sewer heat, or waste heat captured from other processes. The system distributes the heat/cool energy through an underground piping network to heat exchangers located in each building.
