District heating
It may be useful to find out whether a heat network, such as a district heating network, exists or will be built in the vicinity of the building to which it could be connected. District heating networks can draw their energy from the following renewable heat sources and waste heat: lake water, ground water and waste water, but also wood, geothermal and solar thermal energy as well as waste heat from municipal waste incineration plants (MWIP) and industry. A district heating network usually consists of one or more thermal power plants. A network of pipes carries the hot or cold water from the power plant to the heat or cold consumers and then back again. On the consumer side, the heat is distributed through the pipes. Depending on the temperature of the district heating water, it can be used directly for heating and hot water production. If necessary, the temperature can be raised by means of a heat pump.
