Bathroom underfloor heating is usually underneath the waterproofing layer, but the exact location needs to be determined by the actual situation.
Before installing underfloor heating, it is necessary to carry out a waterproof treatment to ensure that the bathroom does not leak. Then, another layer of waterproof layer is set under the floor heating, and the main function of this waterproof layer is to prevent water from penetrating into the insulation layer and backfill layer of the floor heating. For this reason, underfloor heating is usually placed under the waterproofing layer.
However, it is important to note that different homes and renovation situations may have different design and construction methods. In some cases, underfloor heating may be installed on top of the waterproofing layer. Therefore, the specific location needs to be determined according to the actual situation.
What to pay attention to in the installation of floor heating in the bathroom
1. Reasonable design temperature: due to the small area of the toilet and the influence of bathtubs, basins, toilets, etc., the actual heating area is not large. Therefore, the heating design of the bathroom should be designed according to 20--24 to avoid heat loss caused by too high temperature.
2. Strict distinction between dry and wet areas: a rigid anti-ridge can be made at the junction of the dry and wet areas, and the anti-ridge starts from the structural layer to separate the dry and wet areas. In this way, even if there is open water (or water vapor) entering the mortar bonding layer and thermal insulation layer, it cannot reach the dry area, and to a certain extent, the water vapor at the door of the bathroom is avoided from rising and spreading.
3. Double-layer floor drain: double-layer floor drain refers to the original floor drain in the mortar bonding layer, the thermal insulation layer to increase the borehole, to meet the brick surface layer drainage at the same time, if there is open water infiltration into the mortar bonding layer and thermal insulation layer, it can be discharged through the corresponding borehole on the floor drain.
4. Do a good job of the bathroom waterstop wall: to avoid the phenomenon of the bathroom door and floor becoming black.
5. Follow the specifications, reasonable construction, and grasp the details: it is not difficult to do a good job in the waterproof process and install floor heating in the bathroom!
6. Floor laying: When laying the floor, the moisture-proof mat cannot be used underneath, because the moisture-proof mat is heat-insulated, which will affect the heat conduction and increase energy consumption. The insulation board when the floor heating is laid is inherently moisture-resistant and provides the "foot feel" of the floor.
7. Do a good job of waterproof testing and water avoidance measures: This is to avoid the heating of the bathroom from being affected, the temperature should be reasonably designed and a separate thermostat should be set up.
In addition, it is also necessary to pay attention to avoid laying floor heating in the bathroom, because the floor heating in the bathroom is generally spread in the dry area, and it is not recommended to install floor heating in the wet area. At the same time, in order to ensure safety and normal use, it is necessary to choose first-class materials and a professional installation team for construction when installing floor heating.
