Floor heating laying process, the specific process of floor heating laying

The installation process of underfloor heating is as follows:1) Before the installation of floor heating, the floor screed should be inspected.

2) The manifold is horizontally fixed on the wall with 4 expansion bolts, and the installation should be firm.

3) Paste the 10mm corner insulation board along the wall with latex, and the paste is required to be flat and tightly lapped.

4) lay the insulation layer on the leveling layer (such as 2cm thick polystyrene insulation board insulation membrane or imported insulation film, etc.), paste the seam firmly with glue, lay aluminum foil paper or paste a composite aluminized polyester film with coordinate grid line on the Beijing floor heating insulation layer, and the insulation layer should be laid flat.

5) Lay a layer of medium 2mm steel wire mesh on aluminum foil, with a spacing of 100 100mm and a specification of 2m 1m, lay it strictly and tightly, tie it with a cable tie between the steel mesh, and fix the uneven or warped parts on the floor with steel nails. Nails are not allowed to be fixed in rooms with waterproof layers, such as bathrooms and kitchens, and measures should be taken to prevent pipes from exposing the concrete surface when the pipes or steel mesh are warped.

6) According to the heat load calculation requirements made by the professional floor heating company, the floor heating pipe (Pert pipe or PB pipe) is clamped with the floor heating pipe card to fix the pipe on the benzene board, and the spacing between the fixed points is not more than 500mm (according to the direction of the pipe length) The two ends and the midpoint of the curved pipe section greater than 90 ° should be fixed. The bending radius of the pipe should not be less than 8 times the outer diameter of the pipe. During the installation process, the pipeline should be prevented from being polluted, and the nozzle should be blocked in time after the floor heating pipe of each circuit is laid.

Electric underfloor heating laying process.

1. Make a groove in the wall and prepare to install a thermostat in the future.

2. Lay the line pipe in the open groove, and the control line of the electric floor heating passes through here.

3. Clean the site and prepare for the laying of electric floor heating.

4. Lay corner insulation boards to block the heat from floor heating to the corners of the wall.

5. Lay extruded plastic board to block the heat of floor heating from dissipating to the ground.

6. Lay reinforced aluminum foil to reflect the heat of floor heating upward.

7. Place a steel wire mesh on the aluminum foil paper to fix the electric heating pipe above and increase the adhesion of the concrete on the surface.

8. Lay the electric heating pipe on the steel wire mesh and tie it firmly with a plastic cable tie.

9. Thread the control line of the electric heating from the pre-laid line pipe, and install the temperature control panel here in the future.

10. Use the ohm shake meter to measure the resistivity of the paved electric floor heating, if the value reaches 1500 trillion ohms, it is qualified.

Water underfloor heating laying process.

1. The floor of the living room, bedroom, and bathroom has been laid with floor heating, and the shape and color are quite good-looking, and they look very neat and tidy, and these pipes are all through to the end, without interruption.

2. When laying the pipe, it is not to lay it as you want, but to lay it with steel wire mesh. Workers also have work badges on their bodies, which are generally only available to regular construction units.

3. When paving the turning place, there are also strict regulations, the distance must be measured, the position must be fixed, and then the coil is fixed, it seems that the construction process of this company is quite strict.

4. Even if it is laid in parallel, the spacing between them should be strict, so that the ground can be heated more evenly, and the white plastic cable tie next to it is used to fix the coil section by section.

5. The coil tube is Ruihao PEX tube, Ruihao is a good brand, and this tube has a memory function, even if it is accidentally flattened, it can be restored to its original state.

6. In this way, the water is divided into two ways to their respective rooms during heating, in order to prevent the coil from moving casually, the workers also use black plastic pipe cards to fix it, so that the two pipes are kept at a certain distance.

7. From this point of view, the laying structure of the entire floor heating is very clear, and the laying of heat insulation boards, reflective films, steel wire mesh, and coils is not sloppy at all.

8. This is the control valve for heating, through which the warm water is transported to various areas in several ways. The black pipes look clean and tidy, which is convenient for the owner to know the heating situation.

9. Although the host has not yet been hung up, the workers have carefully marked the location and the schematic diagram of each interface, and the preparation work is done well, which can naturally save a lot of trouble when installing the machine.

10. Because the owner's gas consumption is quite large, the workers helped them change a large gas meter after seeking the owner's opinion, although it was only a gesture, but it made the owner feel very heartwarming.
