How is underfloor heating installed on a concrete floor?

Underfloor heating is a popular choice in many homes, as it provides even and pleasant heat throughout the room. When installed on a concrete floor, floor heating is particularly effective, because the concrete stores heat well and releases it evenly. In this article, we go through how to install underfloor heating on a concrete floor step by step.

1. Planning and preparation

Before you start installing underfloor heating, it is important to plan the project carefully. This includes choosing a heating system, purchasing the necessary materials and drawing up an installation plan. It is also recommended to consult a professional to ensure that all requirements and standards are met.

2. Platform preparation

The concrete floor must be clean, dry and level before installing underfloor heating. Remove all debris, dust and any unevenness. If necessary, you can use smoothing compound to smooth the surface of the floor.

3. Installation of thermal insulation

Installing thermal insulation is important so that the heat does not escape downwards. Insulation boards are placed directly on the concrete floor. Make sure that the insulation boards are firmly attached to each other and cover the entire surface of the floor.

4. Installation of underfloor heating cable or pipes

Next, the underfloor heating cables or pipes are installed. This step depends on whether electric underfloor heating or a water circulation system is used.

  • Electric underfloor heating: The cables are attached to the insulation boards according to the manufacturer’s instructions. The cables can be fixed with, for example, fixing straps or clips.
  • Water-circulating underfloor heating: The pipes are installed on top of the insulation boards and fixed in place. Pipes can be fixed with pipe rails or clips, for example. Make sure the pipes are evenly spaced and not too close to each other.

5. Concrete casting

After the underfloor heating cables or pipes have been installed, the next step is concrete pouring. The concrete is carefully poured over the floor heating system and carefully leveled. Make sure that the concrete completely covers the cables or pipes and that the surface is flat.

6. Finishing the floor

After the concrete has dried and hardened, you can finish the floor as you wish. This may include, for example, tiling, parquet or laminate installation. Make sure that the floor material you choose is compatible with underfloor heating.

7. System Testing

Before you start underfloor heating, it is important to test the system. This ensures that everything works correctly and that the heating is evenly distributed. You can perform the testing yourself or with the help of a professional.

Installing underfloor heating on a concrete floor requires careful planning and precise work, but the end result is certainly worth the effort. Underfloor heating provides pleasant and even heat, which increases living comfort and energy efficiency.
