One. Will tatami affect geothermal heating?
Yes.
- Tatami platforms can affect geothermal heating because they have a moisture barrier at the bottom and also have a certain height, which can hinder heat dissipation. However, tatami platforms are not completely unsuitable for geothermal heating. With proper construction techniques, geothermal heating can also be used for tatami platforms.

Two. What is the method for installing underfloor heating with a carpet?
1、When constructing the base cabinet, try to avoid using solid boards that run parallel to the floor. Instead, use boards in strips or individual wooden blocks. This allows the cabinet to be placed directly on the floor without being connected to it, preventing damage to the underfloor heating pipes.
2. The sides of the tatami can be designed with drawers to increase ventilation. The surface of the floor should ideally be covered with a tatami mat, which provides good ventilation and heat retention. Because tatami naturally has excellent breathability, it does not affect the heating performance.
3. The placement of the tatami depends on whether you want to create a subfloor or lay it directly on the floor. If you are creating a subfloor, you will need to drill holes to accommodate underfloor heating. If you are laying the tatami directly on the underfloor heating, you must first thoroughly clean and polish the concrete surface to prevent sand particles from damaging the moisture barrier.
