It is known that ground heating is a comfortable heating method. The indoor surface temperature is uniform, and the room temperature is radiated from the bottom to the top; it does not cause turbid air convection, the room is very clean, improves blood circulation, and promotes metabolism. Thereby forming a thermal environment that truly meets the requirements of human body heat dissipation. The floor heating is suitable for central heating and can also be used for household independent heating, and can realize the requirements of each household to control the temperature. However, many users do not know much about the installation of floor heating. Experts will give a detailed introduction to the installation steps of floor heating.

1. Before the construction, cooperate with the supervision and general contractor to carry out the indoor leveling inspection. If the site does not have the construction conditions or the qualified working site can not meet the floor heating project schedule, under this condition, the floor heating should not be carried out.

2. During the construction of the heating project, the sub-catch and the water collector shall be fixed to the wall in the horizontal direction according to the size requirements of the drawings.

3. Simultaneously with the previous item is the laying of extruded board, the specific requirements are as follows:

(1) Install the extruded board along the periphery of the indoor wall; the part of the bathroom and the room that does not heat the coil is not made of corner insulation.

(2) Laying of extruded boards requires smoothing and splicing; toilets and kitchens are reserved for sanitary ware and kitchen table positions according to the drawings and actual conditions on site.

4. Laying the floor heating pipe according to the requirements of the drawings: the bending radius of the floor heating pipe should not be less than 8 times of the pipe diameter; the plastic pipe tie should be set every 600mm in the straight pipe section in the laying; the plastic pipe tie should be set along the strike distance of the curved pipe section not more than 350mm; When the floor heating pipe is used, two plastic ties should be provided at the bending part.

5. Before connecting the floor heating pipe to the sub-catch and the water collector, the connection size should be measured. The casing should be cut with a casing. The pipe cross-section should be perpendicular to the pipe axis. The debris and burrs should be trimmed and cleaned at the fracture, and the water collector and floor heating should be divided. The pipe joint is a clamp type self-locking connection, and the lock head is tightened after the pipe head is inserted.

6. After all the installation is completed, carry out a pressure test: connect the temporary water source to the water inlet, open the inlet valve and drain valve, fill the water and exhaust until there is no air bubble at the water outlet, press the water to pressurize, and slowly pressurize with the manual pressure test pump. The boosting time is not less than 15 minutes, the test pressure is 1.2Mpa, the pressurization is stopped, the pressure is stabilized for 1 hour, and the pressure is not more than 0.05Mpa within 10 minutes. This work is subject to self-inspection before the next process can be carried out. In this case, it is necessary to make a test pressure record in time and sign it by supervision.

7. After passing a pressure test, the concrete is filled while maintaining a pressure of 0.6 Mpa, and the heating system maintains the pressure during the concrete maintenance period of 48 hours thereafter. Avoid the damage of the outer wall of the heating pipe and the destruction of the floor heating pipe during the concrete filling process.

8. After the curing period of the concrete filling layer is over, it is necessary to carry out the pressing in the second delivery stage. The specific steps of the procedure are carried out according to the first stress test procedure, and the procedures for delivery and inspection are handled.
