How to install wet floor heating in the south?
After the contract is signed, the owner has only two choices: either raise the security door or cut corners! It is more troublesome to improve the security door. Only a few hardcore floor heating owners will spend money to toss their own doors. Most owners are made into non-standard floor heating because they are unprofessional. When installing floor heating, the thickness of cement layer is artificially reduced, and the 5CM pisolite cement backfill layer is made into a 2.5CM cement plastering layer, and the surface cracks seriously reduce the compressive strength; When tiling, only the cement bonding layer with a specified thickness of not less than 3.5CM can be as thin as 2.5CM.
The thickness of wet floor heating tile standard 1 1.5CM was artificially reduced to less than 8CM, which seriously reduced the bonding strength of floor tiles. After 2-3 years, the floor tiles that move frequently will become loose, and there are floor heating pipes below, so the loose floor tiles cannot be re-attached for maintenance, which makes the owners of southern floor heating very headache! Find the floor heating installation master afterwards, and people have already gone to the building.
How to avoid this hidden danger?
When buying floor heating, the owner must choose the appropriate floor heating variety according to his own anti-theft threshold! Don't listen to the rumor that the southern floor heating must store heat. You chose the wrong floor heating! (There is no heat storage regulation in the national standard for floor heating). In addition, the wet cooling in the south requires a large heating load and the price of natural gas is high. It is very important to choose floor heating that can save energy!
At present, thin dry floor heating is widely used in South China. According to the national floor heating standard, the construction atlas is 12K404. The floor heating module is 3CM thick, the floor component is 5CM, and the floor tile component is 7.5CM, which is 7.8CM lower than the south entrance window sill, and does not affect the cement thickness and bonding strength of the tile. So there is no hidden danger of tile loosening in the future! The dry floor heating three-step process is simple in construction and can eradicate the hidden danger of floor noise and shaking. All-aluminum dry floor heating is like a low-temperature radiator laid on the ground, which has the advantages of fast heating and comfortable floor heating. Good ground insulation can make air conditioning cooler in summer, protect floor furniture from moisture and mildew, far-infrared floor heating can warm the body, and multifunctional energy-saving all-aluminum dry floor heating is known as good floor heating in the south, far exceeding the function of single floor heating in winter!
From the point of view of building load-bearing, the dry floor heating module is made of light material, which is very light, about 2 kilograms per square meter, and has no load-bearing requirements for the floor. The cement backfill layer of wet floor heating weighs about 1.20kg per square meter. When installing wet floor heating in high-rise buildings, it is necessary to check the load of the building and strengthen the foundation.
It is very important to save energy in southern floor heating! Dry floor heating adopts all-aluminum plate to conduct heat, which has good heating effect. At the same water temperature, the floor heating surface can be increased by 5 degrees Celsius, and the ground is well insulated. There is no heating downstairs, and the floor heating can be turned off during the day 12 hours without affecting the use. Compared with wet floor heating, the use cost can be saved by more than half, which is very impressive!
The thickness is 5 cm thin, the effect is 5 degrees, and the cost is less than 50%. This is the fundamental reason why all-aluminum dry energy-saving floor heating is popular in the south!
Since 20 19, the national standard for prefabricated buildings clearly stipulates that dry floor heating (No.JGJ/T469-2019) is appropriate. From the policy height of saving social resources and meeting low-carbon energy-saving emission reduction standards, dry energy-saving floor heating technology is encouraged to greatly improve the comfort and energy-saving quality of assembled finely decorated houses.
