What are the installation procedures for dry floor heating? What are the precautions?

Dry floor heating and traditional wet floor heating represent two distinct methods of underfloor heating, each with its own set of installation procedures and considerations. Dry floor heating, for instance, involves placing the heating pipes into slots within an insulated board without any subsequent backfilling. Here’s a more detailed breakdown of the process: 1. **Plan the Pipe Layout**: Start by mapping out the direction of the pipes to ensure optimal heat distribution. 2. **Install the Floor Heating Module**: Lay down the modular components of the dry floor heating system directly onto the leveled cement floor. 3. **Trim the Edges**: Adjust and trim the modules where necessary to fit snugly against walls and other obstacles. 4. **Route the Pipes**: Thread the pipes through the designated channels and secure them using specialized clips. 5. **Pressure Testing**: Conduct a thorough water-filling and pressure test to check for leaks before proceeding. A few key points to keep in mind during installation include ensuring that the floor-free modules rest directly on the flat cement base. Each module has about 1.5 cm of aluminum edges on either side, which connect seamlessly with adjacent modules. These edges are lightly glued together to promote even heat distribution across the area. When laying the pipes, it's common practice to use a back-line approach, especially when dealing with curved sections. This ensures there's enough room for expansion without obstructing the flow of heat. After completing the pressure test, proceed with installing the finishing layer—either floor tiles or pressure strips—using standard protocols. If you're working with a tile-based floor heating module, the process begins similarly: the module is placed directly on the cement floor, featuring a reflective film integrated into its surface. Once the basic structure is in place, the heating pipes are routed over the module following the planned design, secured with specific clips. Next, a wire mesh is laid over the area, with wires tied both horizontally and vertically to further stabilize the setup. Following a rinse and fill with water, the final step involves installing the tiles or ceramics, adhering to conventional methods. This method offers several advantages, including faster installation times compared to wet systems and reduced thermal mass, allowing quicker response times to temperature changes. However, careful attention must be paid to leveling the base properly to avoid uneven heat distribution. Proper sealing and securing of all components are also critical to prevent any future issues related to moisture ingress or structural integrity.
