Efficient heating systems from leading manufacturers of thermostatic valves

In times of increasing environmental awareness and increasing demands for energy saving, modern heating technologies play a decisive role. Thermostatic valves are essential for hydraulic balancing and optimization of heating systems. By precisely controlling and distributing heat, they not only provide greater comfort, but also reduce energy consumption and thus heating costs.

In this article, we introduce you to popular manufacturers of thermostatic valves whose innovative solutions pave the way for more efficient and environmentally friendly heating systems. To find out more about hydraulic balancing, you can check out our detailed article Watch this, which explains everything about hydraulic balancing.

The role of thermostatic valves and hydraulic balancing

Thermostatic valves play a central role in hydraulic balancing, an important process for optimising heating systems. Hydraulic balancing ensures that all radiators in the system are optimally supplied with heat. This is achieved by precisely controlling the flow rate of the heating water, which is regulated by the thermostatic valves. This ensures an even distribution of heat throughout the building, which prevents over or under supply to individual radiators.

Correctly carried out hydraulic balancing results in greater comfort, lower energy costs and a longer life of the heating system. To find out more about hydraulic balancing, you can check out our detailed article Watch this.

How does hydraulic balancing work?

Hydraulic balancing is an important tool for planning heating systems and is mandatory for new installations or renovations. The hydraulic adjustment process can be divided into several steps:

1. Inventory and planning: First, a detailed inventory of the heating system is carried out. This includes all radiators, pipes and valves in the system. In addition, the heating loads of the individual rooms are determined, i.e. how much heat each room requires to reach the desired temperature. You can find more information about room-by-room heating load calculation in our article Roomwise heating load calculation: The path to an optimal heat pump.
2. Calculation of target values: Based on the data obtained, the target values for the volume flow of the heating water to each radiator are calculated. These values indicate how much water must flow through each radiator to provide the required heat output.
3. Thermostatic valve adjustment: The thermostatic valves on each radiator are adjusted so that the calculated flow rate is achieved. The flow rate is the amount of heating water that flows through the radiator and thus provides the required heat. Modern thermostatic valves often have a preset, which makes it possible to precisely regulate the flow.
4. Verification and fine-tuning: After basic adjustment of the thermostatic valves, the system is tested. It is checked whether all rooms reach the desired temperatures and whether the heat distribution is uniform. If necessary, further fine adjustments are made.
5. Documentation and maintenance: The entire process is documented and a maintenance plan is created to ensure that the system also works efficiently over the long term. Regular checks and maintenance are important to ensure the efficiency and functionality of the heating system.

Benefits of hydraulic balancing

Hydraulic balancing offers numerous advantages that can significantly improve both the efficiency of the heating system and living comfort.

energy saving: One of the biggest benefits of hydraulic balancing is energy savings. The optimal distribution of heat ensures that no room receives more energy than necessary, which reduces the house's overall energy consumption. Studies have shown that energy savings of up to 14% are possible through professionally carried out hydraulic balancing (Archive ouverte UNIGE).

Increased comfort: A uniform heat flow ensures a pleasant room climate in all areas of the house. Without hydraulic balancing, it can happen that some rooms are overheated while others do not receive enough heat. The balance creates an even distribution of heat, which heats all rooms evenly and increases living comfort. The room-by-room heating load calculation plays an important role in determining the exact amount of heat for each room. For more information, read our article about the room-by-room heating load calculation.

Longer life of the heating system: Balanced heating mode reduces wear and tear on the components of the heating system. If the system is no longer constantly overloaded or underloaded, the mechanical stress on the components is reduced, which leads to a longer service life of the entire system. This not only saves energy costs in the long term, but also costs for repairs and early replacement of heating components.
