How to choose the best floor heating in Zhengzhou?

First, the choice of brand of floor heating pipeline?

At present, there are many brands of floor heating pipes in the market, such as Jinde, Wei Xing, Jinniu and Rifengdi. For example, some brands earlier than these brands are Korean and Sino-foreign joint venture brands, such as South Korea's Aikang and South Korea's LG, all of which belong to PE-X pipes. Jinniu and Rifeng floor heating pipes are newly launched brands in recent two years, specializing in the production of PPR cold and hot water pipes, which are not as good as Jinde and Hongyuedi in production technology and professional knowledge.

Second, the choice of auxiliary materials for floor heating?

In addition to its own pipes, there are some auxiliary materials for floor heating, such as insulation board, reflective film and concrete cushion. There are two kinds of insulation boards in the market, one is extruded insulation board and the other is white foam insulation board. The best material for home use is the first one. The standard thickness is 2cm, the square is 40KG, and the thickness of the reflective film is 80G, especially the concrete cushion layer, which directly determines whether the floor heating and heat dissipation are uniform. If cement and sand are mixed evenly according to the standard ratio, it is 1:2:3.

Three, the floor heating pipe spacing design specification

The pipeline spacing for floor heating design shall be ￠20, and the pipeline center spacing shall be 225mm. When the floor material is uniform, adjust the time interval according to the room, and the adjustment range is 220 mm-230 mm. When mixing floor materials, in order to avoid excessive temperature difference caused by inconsistent thermal conductivity of floor materials, the pipe spacing of floor tiles is expanded to 250mm, and that of composite floors is reduced to 200 mm..

Four, the floor heating construction operation standard

1, laying polystyrene insulation board, when laying the board, it is not allowed to leave a gap greater than 3mm, and the board surface should be flat and not warped.

2. Heat-proof films shall be laid in an overlapping way, and no gaps shall be left.

3. Before fixing the coil, check the drawings, draw a unidirectional pipeline, leave enough joint size and fix it along the line. The spacing between each pipe clamp should not be greater than 500mm, and the bending radius of the pipe at the corner should be less than 8 times of the outside diameter of the pipe. It is forbidden to use joints in the middle of pipes. When the distance between the two heating pipes is less than 80mm, a thermal insulation sleeve should be added.

After the isolation belt, expansion joint and coil are fixed, the 10mm (thickness) *60mm (height) foam board shall be firmly pasted along the wall column and door. When the length of the room exceeds 6 meters, an expansion joint with a width of 5 mm must be left.

4. Pressurization test: After the water separator is connected to the pipeline, close the valves of the water separator one by one, and then slowly inject water one by one until the air in the pipeline is exhausted and the foreign matter is washed out. Finally, connect a booster pump to pressurize it to above 0.7Mpa, and keep observing for 30 minutes. If the pressure drops more than 0.05Mpa, carefully check the reason until the fault is eliminated. Finally, close the pressure relief valve before removing the pressure pump to maintain the water pressure in the pipeline, at least during the concrete pouring process. In Zhengzhou Antai Floor Heating Company, the pressure gauge was not removed until the end of the renovation, which was the monitoring equipment during the renovation.

5. Floor heating construction workers are professional construction teams, and the workers selected after many examinations are very mature and professional in technology. Zhengzhou Antai Floor Heating Company is in strict accordance with the national floor heating construction industry standard, with foreman in charge of construction management and dress code.

This is the answer.
