Difference between district heating and communal heating

District heating and communal heating are both methods of supplying heat, but they differ significantly in terms of structure, cost distribution, and management. District heating utilizes waste heat from power plants or industrial processes to provide warmth and hot water to homes, while communal heating uses a central heat source, like a communal gas boiler or a connection to the district heating network, to heat a block of houses or an apartment complex. This article explores these differences and the complexities of cost distribution in communal heating systems.

District heating

District heating is a system where heat is supplied to multiple buildings or even entire neighborhoods from a central heat source, such as a power plant, waste incineration plant, or biomass facility. The hot water is transported to connected buildings through a network of pipes. Unlike communal heating, district heating is managed by a separate heat supplier responsible for the maintenance and operation of the heating system.

Users of district heating pay a fixed fee and/or a variable charge based on their actual heat consumption. This makes billing for heat generally simpler and more transparent than in communal heating. The heat supplier sets the rates and bills the users according to local regulations.

Communal heating with a central boiler room

In communal heating with a central boiler room, a building is heated by a central boiler installation located within the building. This boiler provides all apartments or units with hot water for heating and domestic use. The operator of the building, often a housing corporation, property manager, or homeowners' association (VVE or VME), is responsible for the management and maintenance of the central boiler room.

Heating costs are usually divided among residents based on a distribution key, which can be determined by various criteria, such as the size of the apartment, the number of residents, or measured heat consumption. The incoming energy invoice is divided, taking into account heat losses and common areas.

Complexity of cost distribution in communal heating

A major challenge in communal heating is cost distribution. Different distribution keys can lead to confusion and dissatisfaction among residents. Technical issues such as leaking pipes or poor insulation also make it difficult to accurately measure actual heat consumption, complicating cost distribution and causing heat losses.

To mitigate these problems and prevent disputes, building managers need to be transparent about the distribution keys used and communicate effectively with residents about changes in the cost structure. Technological solutions like individual heat meters and smart meters can help measure heat consumption more accurately and make cost distribution fairer.

Conclusion

While both communal heating with a central boiler room and district heating provide heat to buildings, they differ significantly in their structure, management, and billing. Communal heating can be more complex due to various distribution keys and the involvement of building managers in system management and maintenance. Providing residents with a customer portal where they can easily and accurately view their consumption, costs, and invoices can significantly enhance customer satisfaction.
