How to lay floor heating pipes
Floor heating is one of the important ways of heating modern homes. Its laying method directly affects the heating effect and service life. This article will introduce in detail the steps, precautions and common problems of laying floor heating pipes to help you better understand the key points of floor heating laying.
1. Basic steps for laying floor heating pipes
The laying of floor heating pipes needs to be carried out in strict accordance with construction specifications. The following are common laying steps:
| steps | Specific operations |
|---|---|
| 1. Ground cleaning | Make sure the ground is flat and free of debris, and level it if necessary |
| 2. Lay insulation layer | Lay extruded boards or reflective films to reduce heat loss downwards |
| 3. Lay reflective film | Covered on the insulation layer to enhance the upward reflection of heat |
| 4. Install sub-collector | Fixed on the wall or in a special box, connected to the main pipe |
| 5. Lay floor heating pipes | According to the design drawing, the fixed spacing is generally 15-20cm |
| 6. Stress testing | Inject water and pressurize to 0.6MPa, maintain pressure for more than 24 hours |
| 7. Backfilling and leveling | Use pisolite concrete backfill, thickness 3-5cm |
2. Things to note when laying floor heating pipes
1.Pipe spacing control: Different areas have different needs. Generally, the distance between bedrooms and living rooms is 15-20cm, and the bathroom can be enlarged to 10-15cm.
2.Pipe fixing method: It is recommended to use special staples for fixation, with a spacing of 30-50cm, and appropriate density at the corners.
3.Pipeline design: "Back" or "S" shaped pipes should be used to ensure uniform heat distribution.
4.Avoid fixed furniture: Floor heating pipes should not be laid under fixed furniture such as beds and cabinets.
5.Room control: Each room should be equipped with an independent circuit to facilitate temperature adjustment.
3. Comparison of common floor heating laying methods
| Laying method | Advantages | Disadvantages | Applicable scenarios |
|---|---|---|---|
| Serpentine laying | Simple construction and low cost | Uneven temperature distribution | Small room |
| zigzag laying | Uniform temperature distribution | Pipeline usage is large | Large living room |
| double helix laying | High heat dissipation efficiency | Construction is complex | High demand places |
4. Frequently Asked Questions about Floor Heating Laying
1.Q: Can floor heating pipes be spliced?
A: In principle, splicing is not allowed and the entire pipe should be used for laying. In special cases, special connectors must be used and marked.
2.Q: Do expansion joints need to be left when laying floor heating?
A: When the area exceeds 30㎡ or the length exceeds 6m, expansion joints should be set up to prevent thermal expansion and contraction from causing ground cracking.
3.Q: How long does it take for floor heating to be constructed after backfilling?
A: It requires 3-5 days of maintenance in summer and 5-7 days in winter. Subsequent construction can only be carried out after the strength reaches 70%.
4.Q: Will floor heating pipes leak?
A: Pipes produced by regular manufacturers have a 50-year warranty. As long as the construction specifications and pressure tests are passed, there will basically be no leakage problems.
5. Maintenance suggestions after floor heating installation
1. The temperature should be raised slowly when used for the first time, and the temperature should not exceed 5℃ every day.
2. System pressure should be checked every year before the heating season and replenished if necessary.
3. Perform professional cleaning once every 3-5 years to remove sediments in the pipeline.
4. During non-heating seasons, the system should be kept full of water to prevent pipeline oxidation.
Through the above introduction, I believe you have a more comprehensive understanding of the laying of floor heating pipes. Correct laying methods and subsequent maintenance can ensure that the floor heating system operates efficiently and safely for many years. It is recommended to choose a professional construction team for installation to get the best experience.
