How to install floor heating
With the coming of winter, floor heating, as an important way of heating modern homes, has attracted more and more attention from users. In the past 10 days, the discussion about floor heating installation has continued to increase, especially the installation steps, material selection and precautions have become hot topics. This article will combine the hot spots across the Internet to introduce you to the laying method of floor heating in detail, and provide structured data for reference.
1. Basic steps for laying floor heating
Floor heating laying is a systematic project and needs to be strictly followed. The following is a common laying process:
| step | Specific content | Things to note |
|---|---|---|
| 1. Ground treatment | Clean the floor to ensure it is smooth and free of debris | The height difference on the ground must be controlled within 3mm |
| 2. Lay insulation layer | Laying extruded board or polystyrene insulation board | Seams need to be sealed with aluminum foil tape |
| 3. Lay reflective film | Covered with aluminum foil reflective film to enhance heat reflection effect | The reflective film must be smooth and wrinkle-free |
| 4. Install water distributor | Fix the manifold and connect the main pipe | The location of the water distributor should be convenient for later maintenance |
| 5. Lay floor heating pipes | Coil the pipes according to the design drawings, with fixed spacing | The turning radius is not less than 5 times the pipe diameter |
| 6. Stress testing | Inject water and pressurize to 0.6MPa, maintain pressure for 24 hours | If the pressure drop does not exceed 0.05MPa, it is qualified. |
| 7. Backfilling and leveling | Pour pea stone concrete, thickness 3-5cm | The curing period is not less than 7 days |
2. Floor heating laying material selection
In recent hot discussions, users are particularly concerned about the environmental protection and durability of floor heating materials. The following is a performance comparison of mainstream floor heating materials:
| Material type | advantage | shortcoming | Applicable scenarios |
|---|---|---|---|
| PEX pipe | Good flexibility and high temperature resistance | higher price | Suitable for complex house types |
| PERT tube | High cost performance and easy to weld | Average creep resistance | Ordinary residential first choice |
| Aluminum plastic composite pipe | Good thermal conductivity and high strength | Large bending radius | Commonly used in commercial places |
| PB tube | Excellent low temperature resistance | Easy to oxidize and age | Severe cold areas in the north |
3. Five floor heating issues that users are most concerned about recently
According to the statistics of search data on the entire network, the floor heating issues that users are most concerned about in the past 10 days are as follows:
| Ranking | question | Search volume share |
|---|---|---|
| 1 | Price per square meter of floor heating installation | 32.5% |
| 2 | Compatibility of underfloor heating with tile/wooden floors | 25.8% |
| 3 | How to deal with floor heating leaks | 18.3% |
| 4 | Floor heating energy consumption calculation | 12.6% |
| 5 | Can floor heating be installed in the renovation of an old house? | 10.8% |
4. Professional advice
Based on the opinions of many HVAC experts, special attention should be paid when laying floor heating:
1.design stage: It is necessary to calculate the heat load and determine the tube spacing according to the room orientation and insulation conditions. Generally, it is 150-200mm for bedrooms and 200-250mm for living rooms.
2.construction stage: It is recommended to choose a pipeline system with "five layers of protection", including oxygen barrier layer, pressure resistance layer, etc. Use pisolite concrete when backfilling and avoid using sharp gravel.
3.Use stage: The first temperature rise should not exceed 5℃ every day. After reaching the set temperature, keep it for 3 days before normal use. The filter should be cleaned every year before the heating season.
5. New trends in the floor heating industry in 2023
According to industry reports, the floor heating market this year presents the following new characteristics:
| trend | Specific performance | Market share |
|---|---|---|
| Intelligent temperature control | Mobile APP remote control | 45% increase |
| Thin floor heating | Only 3cm height | 28% increase |
| Mixed system | Floor heating + radiator combination | 17% increase |
| renewable energy | Air source floor heating | 62% increase |
Through the above presentation and detailed description of structured data, I believe you will have a more comprehensive understanding of floor heating. In actual construction, it is recommended to choose regular manufacturers and qualified construction teams to ensure the safety and service life of the floor heating system. If you have more questions, you can consult a local HVAC professional for personalized advice.
