Urban heat networks — how they work and who they serve
Poland operates one of the largest district heating systems in Europe. This site documents how heat is produced, transported, and delivered to residential and commercial buildings across Polish cities.
Key Topics
What district heating involves
Heat networks connect centrally operated generation facilities to thousands of end-users through a network of insulated underground pipes. The sections below cover the main components of this system.
Combined heat and power plants
Most Polish district heating relies on combined heat and power (CHP) stations that simultaneously generate electricity and recover thermal energy, improving overall fuel efficiency.
Underground pipe networks
Insulated pre-insulated pipe systems carry hot water at temperatures typically between 70 °C and 130 °C from generation sources to heat substations across the city.
Building-level heat substations
Each connected building has a heat substation where primary network water transfers its energy to the building's internal heating and hot water systems via heat exchangers.
Tariff and metering framework
In Poland, district heat prices are regulated by the Energy Regulatory Office (URE). Consumption is measured using certified heat meters at the point of delivery.
Network efficiency upgrades
EU directives and Polish energy policy are driving upgrades toward lower operating temperatures and integration of renewable heat sources, including geothermal and solar thermal installations.
Rights and complaint procedures
Residential consumers connected to district heating have defined rights regarding supply quality, billing disputes, and the procedure for disconnection or reconnection.
