The calculation of a heating pipe network is a crucial step in the planning of an efficient and reliable heating system. A well-thought-out pipe network ensures even heat distribution in the building, minimizes heat loss and ensures a pleasant indoor climate. This article explains the basics of heating pipe network calculation and highlights the most important aspects for successful planning.

Load calculation and heat distribution: Before the pipe network calculation can begin, it is important to determine the heat requirements of the individual rooms or zones in the building. The load calculation is based on factors such as room size, thermal insulation, window areas, usage and desired room temperature. This information serves as the basis for dimensioning the heating pipe network and distributing the heat energy in the building.

Pipe dimensioning: Pipe dimensioning is a critical aspect of heating pipe network calculation. Choosing the right pipe diameter depends on factors such as heating capacity, flow pressure, flow velocity and pipe length. Under-dimensioning the pipe can lead to insufficient heat flow and increased energy consumption, while over-dimensioning the pipe can lead to unnecessary costs and space requirements.

Hydraulic balancing: Hydraulic balancing plays an important role in heating pipe network calculations, especially in larger buildings or systems with multiple heating circuits. Hydraulic balancing ensures that all radiators or heating circuits in the building receive the right amount of water to achieve the desired room temperature. This ensures even heat distribution and optimises energy consumption.

Pressure loss calculation: When calculating heating pipe networks, it is important to take into account the pressure loss in the system. The pressure loss depends on factors such as pipe diameter, pipe length, flow velocity and any branches. By calculating the pressure loss, the pump power required can be determined to ensure efficient and sufficient water circulation in the heating system.

Regulation and control: A well-planned heating pipe network calculation also includes the selection of the appropriate regulation and control technology. Thermostatic valves, actuators, control units and sensors play a crucial role in controlling the heat output in the individual rooms. Precise regulation enables individual adjustment of the room temperature and contributes to the energy efficiency of the heating system.

In summary, the heating pipe network calculation is a complex process that requires careful planning and knowledge of the various factors. A professional calculation and dimensioning of the heating pipe network is crucial for the efficiency, performance and comfort of the heating system. It is therefore advisable to contact experienced specialists or engineers to ensure that the heating pipe network calculation meets the individual requirements of the building and ensures an optimal indoor climate.
