Definition
District heating is a system in which heat produced centrally (from waste, biomass, heat pumps or surplus heat) is distributed to buildings via insulated hot-water pipes. In Norway, district heating requires a licence and is regulated by NVENorway's Directorate of Water Resources and Energy - regulates the electricity and water resources sectors.. District heating is metered and settled separately from electricity, but digitalisation and smart meters are creating increased interaction between district heating and electricity systems.
