District heating

Dernière mise à jour le 8 September 2017

“District heating, district heating system also distributes heat in a city through pipelines via underground highways. This heat can be in the form of hot water, or water vapor. Users opt for district heating connection-as is the case for gas-and, through a heat exchanger, can benefit from this heat.”

“The first networks were created in the thirties. But it is especially after the 1974 oil crisis and the encouragement of the State that its systems are mainly developed.”

“380 large urban networks, not to mention the networks public and private sites, heat 2.5 million inhabitants in their daily lives, at work or at leisure, and this in over 250 cities.
This represents more than 10,000 kilometers of pipes fed by more than 20 GW, or 6% of the energy consumed by heating in France (1).”

“Heat is generated in large power plants where multiple sources of fuels such as heavy fuel oil, coal, gas, wood, geothermal and garbage can be used. In some cases, a share of energy generated is converted into electricity by a turbine generator. Meanwhile, there are also pipes distributing water very cold (6 degrees) capable of replacing conventional air conditioners.”

“The main advantages of district heating are :

  • control of energy costs,
  • development of multi-energy,
  • possibility to the operations center to the cold”
