Heating network

A conventional heating system consists of three elements :

  • the central boiler room : where the heat that will circulate in the network is produced
  • transmission and distribution pipelines : pipes carrying heat (hot water or steam).
  • substations : heat delivery points. They establish the interface between the heating system and the building.

Energy used :
Heat can be generated from many sources. The energy sources most frequently used by heating networks are as follows :

  • natural gas
  • fuel oil
  • biomass, usually in the form of wood energy (waste wood, pellets)
  • geothermics
  • heat recovered from waste (eg. CADIOM, whose energy is recovered from the Household Waste Incineration Plant at Cheneviers).
