Can be judged from the following aspects:
First, check the business license issued by the Industrial and Commercial Bureau to distinguish between regular companies, leather bag companies and guerrillas.
Second, users who have been renovated are often very aware of the dangers of guerrillas and leather bag companies. Guerrillas are easy to identify. As we all know, the business license issued by the industrial and commercial bureau is the basis of the company's legal operation, and whether the business license has the "annual inspection certificate" of the industrial and commercial bureau is the premise of the company's continuous operation, otherwise it will be an illegal guerrilla. Now that the company registration is simple, how can we distinguish between a regular company and a domestic company? See if the registered address of the company on the business license is consistent with the actual business address. Users should not be confused by the nonsense of the leather bag company.
Second, check the professional qualifications of the Construction Committee and distinguish between professional companies and non-professional companies.
The construction qualification of floor heating specialty is a kind of recognition of the professional ability of construction enterprises by the construction administrative department. As far as Beijing area is concerned, Beijing Municipal Construction Committee examines construction enterprises in terms of registered capital, technical personnel qualification, construction capacity, construction equipment and tools, and construction performance. The state stipulates that enterprises engaged in floor heating construction should have professional qualifications, but this is not the case. There are many enterprises engaged in floor heating construction, which are not qualified or cooperate with qualified subsidiaries and business departments in the form of affiliation, and have no professional technical force. The quality of floor heating can be imagined.
Third, check the product authorization certificate to identify the source of the main material of floor heating.
4. Products are the basis for the safety of the floor heating system. The products produced by professional manufacturers must be tested and certified by relevant state departments. Manufacturers often choose powerful installation companies for authorization after specific inspection and screening work and a series of training procedures, and are responsible for the authenticity of products used by authorized floor heating companies and the safety of product quality. After the product is installed by an unauthorized enterprise, if there are problems in the system in the future, the manufacturer will not be responsible for the possible product quality. Merchants who cross goods often run away because of their limited strength, and users can only bear the losses themselves. Now many companies say that they are authorized agents of a floor heating brand product. On the one hand, these so-called authorized agents cut corners and shoddy goods. On the other hand, they clearly claim that they are agents of product A. When users show their preference for product B, they will again. In fact, no professional manufacturer has more than three authorized enterprises in a region. At the same time, regular manufacturers generally have some exclusive restrictions on authorized enterprises when authorizing products, that is, authorized enterprises are generally not allowed to operate products of multiple brands at the same time. Does the user judge whether the product source is formal? It's simple. Check the authorization certificate of the installation enterprise, call the manufacturer for confirmation and visit the warehouse of the installation enterprise.
Four, determine the strength of the company, field trips, office space, warehouses, venues, one can not be less.
At present, many companies in the floor heating industry are very small. Generally, three or five relatives and friends form a company and move a desk to work. Such companies are often unreliable. As we all know, management should be people-oriented. At present, professional floor heating companies have a clear division of labor in design, product selection, installation, debugging, quality inspection and after-sales service, while more formal floor heating companies generally have more than 20 managers. The most direct way to identify the strength of the floor heating company is to go to the office address of the floor heating company to see the company's scale, office environment and the mental outlook of the staff.
Secondly, visit the warehouse of the floor heating company. Regular floor heating companies are often authorized agents of a certain brand of products, which requires them to build warehouses of several hundred square meters. Millions of stocks are there, and the strength of the company and the number of orders received are clear at a glance. Users will not worry that such companies will disappear overnight like guerrillas and leather bag companies.
Third, look at the construction site. There is a saying in the floor heating industry: whether it is good or not, the construction site has the final say. The skill and management level of a company's construction force can best be reflected in the ongoing construction site. The amount of construction is also a direct reflection of the strength of the floor heating site. Powerful floor heating companies basically start construction on the construction site every day. Regardless of the distance, users insist on watching it, which can often break all kinds of nonsense of many floor heating companies.
Verb (abbreviation of verb) understands the operating history and construction achievements of floor heating company.
At present, many companies in the floor heating industry take advantage of the uncertain market to make a fortune, cut corners, manage irregularly, and even run away or change doors when problems arise. Such companies often wear the cloak of low prices, but in fact they are profitable. As a result, some new companies will open every year, and many companies will be eliminated or disappeared every year. There is a saying in the floor heating industry: the brand floor heating company made it. Imagine that in the face of the price shock of guerrillas and leather bag companies, a considerable amount of construction achievements have been completed in a long time, and its system can still operate normally, which in itself can explain the problem.
A company should enter the field of floor heating for three years. Here users should pay attention to avoid two companies: one is not a dry floor heating company, and the gold rush in the floor heating industry is not long; Another company is heating, air conditioning, hydropower transformation, and even decoration. This kind of company often takes advantage of the owner's fear of trouble, and everything is easy to handle. In the end, it is often the customer who is unlucky.
The performance of construction should pay attention to the performance of home improvement and floor heating made by others themselves, not to any one million square meters project. There is a great difference between engineering floor heating and home decoration floor heating. The performance covers more than 50 residential areas in Nanjing. Generally, there is no question mark about the authenticity of the performance of the floor heating company when users are unfamiliar with or have not heard of the acquisition of the community. Users can ask to contact users in the cell they want to know to get actual feedback.
Intransitive verbs beware of over-commitment, so as not to suffer the consequences.
Many users are too pursuing perfection in decoration, so there are always many companies in the floor heating industry who "have to" make excessive commitments in order to grab orders and cater to these users. While condemning these companies for being misleading and irresponsible, we also advise users to be wary of over-commitment and avoid self-harm.
For example, at present, domestic insurance companies have not installed construction quality liability insurance. Some users insist that the floor heating company promises that if there is a problem with the floor heating, the floor heating company will bear all direct and indirect losses. At this time, there is often an interesting phenomenon in the market. The more guerrillas and small companies dare to ensure quality, including metal connectors and temperature control panels, they dare to promise 50 years of life. Some users ignore the fact that the floor heating company can't control the wall insulation conditions, the water temperature of the heat source and the heating load, ignore the suggestions of the professional company on insulation renovation and heat source renovation, and blindly ask the floor heating company to promise to reach a certain temperature; Some users even ask the floor heating company to promise to choose "absolutely environmentally friendly" materials, which often makes honest companies feel at a loss. Therefore, users are advised not to trust companies with empty, excessive or even false promises, so as to avoid terms that cannot be issued in the current market reality. The technical strength, influence in the industry, accumulation of experience and standardized management of the enterprise are the real guarantee for the safety of floor heating, and the honest company is trustworthy.
With the wide application of floor heating system, many people are no longer completely unfamiliar with floor heating. But most people still have a little knowledge of floor heating. They only know the advantages of floor heating, such as energy saving, comfort, environmental protection and health, but they don't know the preconditions that floor heating must meet to reflect the above advantages. This understanding of floor heating by consumers objectively provides opportunities for some floor heating companies-some floor heating companies set many traps in the process of contracting and delivering floor heating projects, aiming at the characteristics that consumers have little knowledge of floor heating, leaving many hidden dangers for floor heating projects. Combined with some phenomena in the floor heating market, the author reminds consumers to beware of the following traps of unscrupulous floor heating companies:
Jerry-built floor heating system is not like many people think, just put some pipes on the floor. It needs professional and technical personnel to measure on the spot, and on the basis of accurate calculation, design the heating scheme according to local conditions. However, in order to reduce the cost, some floor heating companies always try their best to cut corners after receiving the floor heating project. And people in the industry know that the omission of some materials in the floor heating system will bury many hidden dangers for the operation of the floor heating system. Take the mixed water temperature control center as an example. If there is no mixed water temperature control center in central heating district, the high temperature water of central heating will accelerate the aging process of floor heating pipeline, and may even paralyze the floor heating system after one or two years. Many floor heating construction enterprises will encounter some ultra-low-priced bidding enterprises in the bidding process of floor heating projects. These ultra-low-priced bidding companies sometimes quote very low prices, but the floor heating materials they promise to use are no different from those promised by other bidding companies in terms of brand, quality and model. Are these companies really "losing money and earning money"? In fact, people in the industry know that these ultra-low-standard enterprises often fill the gap caused by their low quotations by cutting corners during the construction process. Everyone in the industry knows that if the coil spacing of a floor heating project is 200 mm, then a 6-meter floor heating pipeline needs to be laid for one square meter. Some owners don't know about this, and they are often not on site during construction, which leaves an opportunity for enterprises that bid at ultra-low prices-secretly increasing the spacing of floor heating pipes during construction. According to the calculation of saving 2 meters of floor heating pipes in a square meter floor heating project, a villa with a heating area of 300 square meters can save 600 meters of floor heating pipes. Therefore, when choosing a floor heating company, the owner must not be confused by the ultra-low price of the low-priced winning company, so as not to jump into the trap of unscrupulous floor heating companies.
As everyone in the random design industry knows, a standardized floor heating project needs to go through procedures such as design, drawing and drawing. But some floor heating companies don't have cartographers at all. In the process of contracting floor heating projects, these floor heating companies often find a cartographer to draw a picture casually to perfunctory owners. Some floor heating companies don't go to the site for field measurement at all, and directly let the owners send the drawings and make drawings directly according to these drawings. Obviously, this is all irresponsible behavior. Because there is a big difference between the floor heating system in home decoration and the floor heating system in tooling: when the owner designs the floor heating system in home decoration, he will change the indoor pattern and furniture placement position at any time, which requires the floor heating company to conduct field measurement in time, and after carefully reviewing the drawings, through the procedures of design, drawing, scheme and so on, lay out the floor heating project suitable for the specific situation of the owner's home. Some owners don't want to go to the floor heating site to save trouble. In fact, doing so often provides an opportunity for unscrupulous floor heating companies.
Savage construction Everyone knows that design is very important for the floor heating system. In fact, construction is as important as design for floor heating system. If a perfect floor heating system design scheme is not handed over to a professional construction team for construction, the rationality of the floor heating project can still not be guaranteed. Practice has proved that many problems in floor heating engineering are caused by irregular construction. For example, once the supply return pipe of the floor heating distribution main pipe is connected reversely, it is difficult to raise the indoor temperature no matter how it is debugged. In the end, it can only be reloaded with water, which wastes both water and time; If the spacing of floor heating coils is uneven, it will lead to uneven indoor heat and cold. However, once the uneven floor heating pipe is buried by the filling layer, it will not be changed; If you don't follow the diagram, there will be endless troubles: in the future, not only can you not find the corresponding room position of each branch, but it is also not conducive to room temperature debugging. Therefore, in order to make the floor heating system reflect energy saving and comfort, it must be constructed by a professional floor heating company.
To sum up, consumers must be cautious when choosing floor heating construction enterprises, and don't pay too much attention to the quotation of floor heating companies. They should choose a strong and responsible floor heating construction enterprise.
