District heating is an underground infrastructure asset where thermal energy is provided to multiple buildings from a central energy plant or plants. Steam or hot water produced at the plant is transmitted 24/7 through highly insulated underground thermal piping networks.
Is district heating expensive?
In percentages, the annual cost of district heating is approximately 19 % lower than an individual natural gas boiler and approximately 30-31 % cheaper than an individual biomass boiler and an individual air-to-water heat pump.
How does a district heating network work?
Through a district heating network, the heat-producing plant pumps heated supply water to consumers where it is used as room-/floor-heating and to generate domestic hot water. The domestic hot water gets heated in a heat exchanger in which the heated supply water transfers its heat to the water coming out of the taps.
