Floor heating installation is divided into six steps, and backfilling is the key!

As the temperature drops and winter comes, it's time for heating equipment to play again. Radiant floor heating, which radiates heat evenly from bottom to top, makes the temperature on the same floor of the room uniform, the temperature difference is small, and the comfortable experience of warm feet and cool roof is accepted by more and more families. So, today I will take you to discuss the steps of floor heating installation.

First, the floor heating installation steps

1, leveling the ground is the premise of installing floor heating. If the ground is uneven, it will not only affect the floor heating and insulation, but even if there are sharp things, it will cut the floor heating pipeline. When leveling the ground, the bumps must be cleared to 10mm first, and the ground sundries should be cleaned up to ensure the ground is flat, and the walls and column feet are at right angles to the ground.

2. Install the distribution manifold. Install the distribution manifold horizontally at the position specified in the figure, with the water separator above and the water collector below, with a distance of 200 mm. The height of the center of the water collector from the ground is not less than 300mm, and it shall be installed firmly.

3, laying insulation layer reflective film on the leveling layer laying insulation layer, plate seam with glue firmly, the insulation layer should be laid flat. Reflective film should be laid on the insulation board, keep flat and wrinkle-free, and cover tightly.

4. Laying coil The floor heating coil should be laid in strict accordance with the design and construction drawings, consistent with the design loop, and the pipeline laying spacing should be consistent with the design. Pipes near areas with high heat consumption, such as external walls, windows and vacant floors, should be encrypted, and pipes should be fixed on composite insulation boards and reflective films with plastic clips.

5. Pipeline hydrostatic test After checking whether the heating pipeline laid by floor heating is damaged and whether the pipe spacing meets the design requirements, water is injected from the water injection exhaust valve for hydrostatic test, and the test pressure is adjusted. After the pressure is stable, it is considered as qualified.

6. Backfilling and leveling the ground The general floor heating project is to smooth it with cement mortar, and the ground elevation difference after concrete leveling shall not be greater than 5 mm When laying concrete, it must be marked at the door, corridor and floor drain. Prevent improper behavior from damaging the floor heating pipeline in the later construction.

Second, the floor heating backfill construction

1, construction conditions Before construction, the floor heating coil should be installed and the concrete filling should be completed within two days after the water pressure test is qualified; The heating cable has passed the resistance test and insulation performance test; The heating pipe is installed and the water pressure test is qualified, and the heating pipe is under pressure; The installation box of thermostat and the cold threading of heating cable have been arranged; Pass the acceptance of concealed works.

2. Precautions for construction In the laying area of heating pipes or heating cables, it is forbidden to make holes, drill holes or shoot nails; During construction, protective measures should be taken for the ground, and it is forbidden to overload, bake at high temperature, and directly place high-temperature objects and high-temperature heating equipment on the ground; Construction workers should wear soft-soled shoes and use flat-headed shovels to prevent the trolley from crushing the floor heating system; When backfilling with floor heating, the pouring area should not be too large each time to avoid temperature cracks in concrete; Before the system starts heating, the curing period of concrete filling layer should not be less than 7 days.

The pursuit of better ground insulation requires us to pay attention not only to the quality of ground insulation materials, but also to the construction specifications of products. A good product must have a good and correct construction scheme to achieve the expected effect. Well, the above is the installation steps of floor heating introduced by Bian Xiao, hoping to bring you help!
