7. Laying of heating cable: lay the cable according to the design drawing, connect one end of the cable and the temperature sensor, and the PVC embedded pipe passing through the ground to the bottom box of the thermostat, and then fix and tile.

8. Detect the cable again: After the cable laying of the electric floor heating is completed, the cable needs to be tested again, mainly to detect its nominal resistance and insulation resistance, and the detection method is the same as the previous test.

9. Installation of thermostat: thread the floor temperature probe through the tube, and the end of the tube should be closed and set between the two cables as much as possible, and fixed with a trapped cable tie and steel wire mesh.

10. Power-on detection: After the thermostat is installed, if there are conditions, it is necessary to carry out power-on detection to check whether the cable is hot, and to detect whether the heat is uniform everywhere in the cable.

11. Filled concrete: pouring concrete filling layer, the materials used must meet the design requirements, the concrete must be transported by a backing plate when entering the laying area, and it is not allowed to step on it within 48 hours after the filling is completed, and it is strictly forbidden to chisel and reload.

12. Test and acceptance after the installation of electric floor heating: after the expiration of the curing period of the concrete filling layer, when starting and debugging the heating cable heating system, the system should be set to run in the low temperature range of 5 10 for a period of time, and then gradually increase the temperature until the comfortable temperature of heating is reached.

Electric floor heating is generally in 60 150 yuan, this is the average price of floor heating coils, does not include labor costs, including reflective film, backfill and other basic materials, only calculate the effective pavement area, in order to better control the budget, 145 square meters of the actual pavement area in 95 square meters 120 square meters of construction area of 78 square meters to 80 square meters of construction area of 52 square meters of floor heating and so on can calculate their own effective pavement area. Factors affecting electric floor heating 1. The cost of auxiliary materials In addition to the main materials such as heating cables and electric heating films, there are also auxiliary materials such as insulation boards, steel wire mesh, nylon belts, and reflective films. These auxiliary materials are also one of the influencing factors of electric underfloor heating**.

Generally, it is necessary to choose auxiliary materials with good corrosion resistance, because the auxiliary materials of electric floor heating are buried in the ground, and they can be easily damaged if they are not corrosion-resistant. Good electric floor heating auxiliary materials can reduce heat loss, can improve the effect of electric floor heating and save electricity bills. At present, the quality of electric floor heating auxiliary materials on the market is good and bad, of course, there is a big difference.

The heating effect of floor heating is very good, so it is now more and more widely used. But in fact, floor heating should also be divided into types, and now many people choose electric floor heating installation. Because the installation of electric floor heating is simpler and the use effect is also very good, what are the steps and skills of electric floor heating installation?

First of all, we must lay a moisture-proof layer on the ground of the base layer, and then lay the steel wire mesh and heating cable, after the installation is completed, the heating cable can be tested, and if there is no problem, it can be put into use!

In the first step of electric floor heating installation, we must first clean the base floor, try to keep the ground flat, and then start laying the moisture-proof layer. Generally, electric floor heating is installed under the floor, so be sure to lay a moisture-proof layer to avoid damage to the floor heating system caused by moisture.

The second step of electric floor heating installation, after laying the moisture-proof layer, the installation of electric floor heating can be carried out. Lay the steel wire mesh on the moisture-proof layer, and fix the joint with a lashing belt, or fix it with a staple, in order to avoid leaving trouble for future use, it is best to fix it firmly.

In the third step of electric floor heating installation, you can install the heating cable. The heating cable must be installed as a whole in accordance with the requirements of the design drawings, and must be laid on the steel wire mesh according to the spacing on the drawings. When laying, try to keep it flat, and then use a lashing belt or a nail to fix the heating cable on the steel wire mesh.

After the installation of the heating cable is finally installed, check whether it meets the requirements of the drawing, and use a multimeter and a shake meter to detect the nominal resistance and insulation resistance of each cable to ensure that the heating cable is not open or short-circuited. Finally, the power-on test is carried out to check the heating effect of the electric floor heating, and if there is no problem, it can be put into use.

That's all for the installation of electric underfloor heating. If you want to install floor heating by yourself, then you must understand, a certain amount of professional knowledge, and the overall construction steps!

Electric underfloor heating is a method of heating using electricity to provide a comfortable indoor temperature. The following is the installation and construction method of electric underfloor heating.

First of all, before installation, it is necessary to confirm whether the foundation treatment of the installed ground is completed and whether the ground area is consistent with the size of the electric floor heating. Secondly, it is necessary to determine whether the power wiring meets the requirements, and a leakage protection spring marker should be configured between the floor heating electrical device, the power supply and the ground wire.

Next, a thermal conductive layer needs to be laid. The thermal conductive layer allows for better heat transfer to the ground and improves heating efficiency. The thermal conductive layer can be foam or bubble.

When using a foam thermal conductive layer, it is recommended to choose a high-density foam thermal conductive layer with a thickness of 5 mm or more that is hard and pressure-resistant. Attention should be paid to the contact between the thermal conductive layer and the indoor ground level, without loosening and empty seams.

Then, you need to install electric floor heaters. Arrange the warm sheets on the thermal conductivity layer in turn, and store them with the wires. In general, the connection method should be changed accordingly depending on the application.

Next, install a protective film on top of the electric floor heating sheet. The selection of protective film should consider strength, pressure resistance, waterproofness and air permeability to ensure the service life of the ground.

Finally, the flooring installation is carried out. If wooden flooring is installed, it should be left on for a period of time before installation to allow the floor to fully acclimatize to the environment. In addition, the flooring should be installed on top of a protective film, and multi-layer panels and composite flooring can be selected.

In summary, the installation of electric underfloor heating requires certain professional skills and experience, and if you need to install electric underfloor heating at home, be sure to seek the help of a professional.
