Floor heating "difficulty" diffuse

"The floor heating has caused a large amount of formaldehyde to be released from the floor, problems have arisen in maintenance, and the floor has brought about respiratory diseases and blood diseases..." Recently, with the advent of the heating season, all kinds of hazards related to "floor heating" have been greatly affected.

Some people think that these arguments are “warm up” and are intentionally hurt because the floor heating grabs the market share of heating.

Others believe that after entering the fine-tuned housing project, due to the low cost of the developers, the use of sub-standard small plants to lay floor heating has triggered conditions such as floor heating bursts, water leaks, and inability to maintain, which has negatively affected the originally stable heating market. The effect; Some people believe that the heating industry is a mixed bag, and there are irregularities in the quality of floor heating, installation, auxiliary materials, and operation, resulting in certain safety hazards in floor heating.

What happened in the end?

The winter is approaching, and heating in the home is a common and often new issue in every winter. In recent days, the “legends” about several major hazards in floor heating have spread widely. “To warm the floor, a large amount of formaldehyde is released, problems arise in maintenance, and the floor warmth brings respiratory diseases and blood diseases...” Floor heating will completely dissipate cooling equipment (floor heating pipes). Placed under the floor, this is its advantage, but it seems to have become a huge hidden danger. Many problems caused by heating methods have become hot topics.

Is it ** or rumors? Will the market chaos be able to conclude that the ground heating is useless? Where does the statement of "three-point product and seven-point installation" come from? The heating time is getting closer, and the reporter has conducted a series of visits to find out. Reread "to warm."

It can be found that in fact, behind the "N hazards", there are many hidden dangers hidden in China.

In the floor heating industry, miscellaneous non-standard construction abounds in the face of all the above-mentioned “arguments” about floor heating. A well-known floor vendor has told reporters that there are some misunderstandings here. The reason is that the unstandardized floor heating merchants make the floor warm and “humiliated”. .

The person in charge of the brand revealed to reporters that at the moment, small companies with various names of “floor heating companies” are blindly rushing into the field of warm construction. Driven by interests, the construction process often intentionally or unintentionally lowers construction standards and cuts down on materials. It is because of this that it brings many hidden dangers to the floor heating project. Their non-standard behavior has become the hotbed of criticism.

In fact, floor heating has a very rigid regulatory process. According to floor heating technicians, floor heating pipes should first be installed in the room and then covered with a concrete layer. Finally, the upper layer of concrete should be paved with floor tiles, or stone and wood floors.

It is because of this that the floor heating pipe is hidden under the floor and under the concrete. Once the problem arises, it is not easy to repair. Because it is impossible to confirm the location of the problem, if there is a leakage point or blocking point, it may require a large area to open the ground until the problem is found. After that, backfilling the concrete and replacing the floor, etc., are complicated and consume human and material resources.

As a system project, the floor heating industry is known as “three-point product, seven-point installation”. Consumers must look for reliable, competent and regular companies. They must not be coveted and plan to save time. They can easily find small vendors or mobile vendors in the community. Once a problem arises, the seller is likely to slip away from the loss. Consumers themselves.

The choice of floor heating method requires the consumers to comprehensively consider the selection of floor heating materials and flooring materials. The floor heating expert reminds that the installation process needs to be very standardized, and at the same time, it is necessary to understand the heating water temperature and other operational procedures in the area where he is heating. If one of the contents is not handled properly, it may cause trouble for future use.

The lack of compliance with the selection of materials to warm the hidden danger Although there are "seven-point installation," but there is no doubt that the selection of heating is still the key to its future use. Floor heating and floors cannot be ignored. Consumers must pay attention to the fact that if the main heating materials and auxiliary materials such as floor heating pipes, joints, and temperature control valves fail to meet the standards, serious problems may be caused.

The technicians further explained that the floor heating pipe is the most important thing, and its oxygen blocking ability (blocking oxygen penetration into the pipe can greatly extend the service life of metal valves, switches, boilers, manifolds and other metal parts in the entire pipe system), Compressive strength, flexibility, aging resistance, etc. will directly determine the safety and service life of the entire floor heating system.

At the same time, the floor quality above floor heating is also crucial. The floor heating is heated from under the floor, making people feel warm feet, which is one of the selling points of the floor heating. However, if the floor is not properly selected, it may indeed pose a health risk.

Floor experts remind consumers that due to the fact that wood is susceptible to baking deformation and the problem of solid wood floors laying keels, floor heating can only generally use composite wood floors, and composite wood floors are used in large quantities to contain organic solvents ( Such as formaldehyde and stupid, etc.) glue.

The amount of formaldehyde released by the glue at room temperature conforms to the calibration level. However, when the local heating is heated, the temperature of the floor is increased. Especially in cold regions, the heat load is large, the required floor temperature is high, and the amount of formaldehyde released will exceed the standard. , Harmful to human health, which is also one of the reasons why many European countries such as Germany stipulate that the floor surface temperature does not exceed 30°C.

Therefore, some experts suggest that floor heating is best used with concrete floors or floor tiles. In contrast, other heating equipment (such as air conditioners, heating, etc.) are not directly close to baking the floor because they are heated air, so it will not cause obvious increase of formaldehyde emission from wood floors, and there is no excessive restriction on floor materials. Blindly raising the water temperature makes floor heating unbearable. There is no problem with the design and construction, but there is no problem with the selection of materials, but there is still a problem with floor heating. Why? Because the water supply temperature of floor heating is too high and the coil ruptures.

In fact, floor heating, also known as floor low-temperature radiant heating system, emphasizes low temperature, and the ground surface temperature should not exceed 30 degrees. This is not only comfortable but also prolongs the life of floor heating and floor heating. However, in actual use, there are often people. It is not only uncomfortable but also brings many problems.

A person from a real estate development party disclosed to reporters that some developers and floor heaters deliberately reduce the amount of coils in order to reduce the initial installation cost, resulting in a decrease in the room temperature at the same temperature of the incoming and returning water in the later operation. , lower than the legal room temperature. This has brought difficulties to the post-property company's warm-up operation and maintenance. In the coldest time, the ground warming and over-temperature operation have seriously affected its life span.

In addition, the high heat load in the high-cold area, heating can not meet the heating is also one of the reasons for warm and over-temperature operation. Therefore, heating experts suggest that floor heating is not suitable for use in particularly cold areas. If floor heating is used, heating should generally be supplemented by adding radiators, and the warm water heating temperature must not be increased.

"High temperature" floor heating may bring a series of problems: such as shortening the floor heating and the life of the floor itself; long-term residence will cause the residents to have swollen feet, varicose veins and other health risks; the indoor formaldehyde content exceeds the standard ... so the heating system to warm The water temperature (no more than 60°C) and the floor surface temperature are very tight.

Floor heating, as one of the new heating methods emerging in recent years, has its advantages, comfort, beauty, etc., as well as its limitations. The cause of hidden dangers and problems in the ground may not be its own, it may be caused by some improper operation behind it. Consumers should not listen to unfounded words. When choosing to warm products, we must first understand these issues and make a screening. If you choose, you must be prepared to prevent and prepare.
