How to lay wooden floor on floor heating
As winter approaches, floor heating systems have become the preferred heating method for many families. However, laying wooden floors over floor heating requires special attention to materials and construction methods to ensure the floor heating effect and the durability of the wooden floor. This article will detail the steps, precautions, and answers to frequently asked questions about laying wooden floors over floor heating.
1. Things to note when laying wooden floors over floor heating

When laying wooden floors over floor heating, you need to pay special attention to the following points:
| Things to note | Detailed description |
|---|---|
| Choose the right floor material | It is recommended to use composite flooring or solid wood composite flooring, and avoid using pure solid wood flooring, because solid wood is easily deformed by heat. |
| Control floor heating temperature | Before laying, the floor heating temperature needs to be adjusted to 18-22°C. After laying, the temperature gradually increases to avoid sudden changes in temperature that may cause floor cracking. |
| Reserve expansion joints | An 8-10mm expansion joint needs to be reserved between the floor and the wall to prevent thermal expansion and contraction from causing the floor to arch. |
| Use special floor mats | Choose floor mats with good thermal conductivity and avoid using ordinary foam floor mats to avoid affecting the floor heating effect. |
2. Steps to lay wooden floor on floor heating
The following are the specific steps for laying wooden floors over underfloor heating:
| steps | Operating Instructions |
|---|---|
| 1. Ground inspection | Make sure the floor is smooth, dry and free of cracks or unevenness. |
| 2. Lay moisture-proof membrane | Lay a moisture-proof membrane on the floor heating pipes to prevent moisture from penetrating into the floor. |
| 3. Lay floor mats | Choose floor mats with good thermal conductivity. When laying, pay attention to the overlap of seams by more than 5cm. |
| 4. Lay wooden floors | Start laying from a corner of the room, pay attention to reserve expansion joints, and use special glue or locks to fix it. |
| 5. Install baseboards | When installing baseboards, be sure to cover expansion joints to ensure a beautiful appearance. |
3. Frequently Asked Questions
When laying wooden floors over underfloor heating, you may encounter the following problems:
| question | solution |
|---|---|
| cracked floor | It may be caused by the rapid temperature change. It is recommended to slowly increase the temperature and maintain indoor humidity. |
| Arched floor | Check that expansion joints are adequate and re-floor if necessary. |
| Poor floor heating effect | Check whether the floor mat conducts heat well and avoid using overly thick floor mats. |
4. Summary
Laying wooden floors over floor heating requires special attention to material selection and construction methods to ensure the floor heating effect and the durability of the floor. Choosing the right floor material, controlling the floor heating temperature, preparing expansion joints and using special floor mats are key steps. Through the above methods, you can avoid floor cracking, arching and other problems, and enjoy a comfortable winter heating experience.
If you still have questions about laying wooden floors over underfloor heating, it is recommended to consult a professional construction team for more detailed guidance.
