How to install the main pipe for floor heating
As winter approaches, floor heating systems have become the first choice for heating many homes. The installation of main pipes for floor heating is a key link in the entire system, which directly affects the heating effect and safety. This article will introduce in detail the installation steps, precautions and related data of the main floor heating pipe to help you better understand this process.
1. Basic steps for installing floor heating main pipes

1.design planning: Before installation, the direction and layout of the main pipes need to be designed according to the house area and structure to ensure even heat distribution.
2.Material preparation: Choose high-quality pipe materials. Common ones include PEX pipes, PB pipes and aluminum-plastic composite pipes.
3.Pipe laying: Lay the main pipeline according to the design drawings. Pay attention to keeping the pipeline straight and fixed to avoid bending or twisting.
4.Connections and seals: Use professional connectors and sealants to ensure there are no leaks at pipe connections.
5.stress test: After installation is completed, perform a pressure test to check whether the system is leaking air or water.
2. Precautions for installing floor heating main pipes
1.avoid crossing: The main pipeline should be kept at a certain distance from other pipelines (such as water pipes and wires) to avoid cross interference.
2.Insulation treatment: Install an insulation layer on the outside of the pipe to reduce heat loss.
3.Slope design: The main pipeline should have a certain slope to facilitate drainage and exhaust.
4.Regular maintenance: After installation, check the pipes regularly for aging or damage and repair them in time.
3. Relevant data on the installation of floor heating main pipes
| Project | data |
|---|---|
| Main pipe material | PEX pipe, PB pipe, aluminum-plastic composite pipe |
| Pipe diameter | Usually 20mm-32mm |
| Paving spacing | 200mm-300mm |
| Pressure test value | 1.5 times working pressure, maintain 24 hours |
| Thickness of insulation layer | 20mm-30mm |
4. Frequently Asked Questions about Floor Heating Main Pipe Installation
1.Leaking pipes: Usually caused by loose connections or material quality issues, the damaged parts need to be rechecked and replaced.
2.Uneven heat: It may be that the spacing between pipelines is unreasonable and the pipeline layout needs to be adjusted.
3.Noise problem: The air in the pipe is not exhausted or the water flow speed is too fast. It is necessary to exhaust the air and adjust the water flow speed.
5. Summary
The installation of main floor heating pipes is a highly technical task that requires professional design and construction. Through reasonable planning, high-quality materials and rigorous testing, the efficient operation and long-term use of the floor heating system can be ensured. If you have any questions about the installation process, it is recommended to consult a professional floor heating installation company.
