How to distinguish the quality of wall-hung boiler? How to choose?

There is a saying that "existence is reasonable". Although we have no right to decide whether to use the wall-hung boiler, we have the right to choose and identify it. How to judge the quality of wall-hung boiler when buying a house? Moreover, what should you pay attention to when you are dissatisfied with the brand of wall-hung boiler provided by the developer and want to replace it, or need to replace it after several years of use? The "owner" believes that whether it is "approval" when buying a house or "choice" when replacing it, there are nothing more than the following three essentials.

Main point 1: See if it is a good brand. Generally speaking, brand-name products are safer to use. Not only the quality of its products is more guaranteed, but also its after-sales service can be better guaranteed. At present, some famous brands in Germany and France are very good. In addition, it depends on whether the wall-hung boiler is insured. If there is an accident, it is best to find the relevant unit to pay.

The second point: see if electricity can meet the heating needs of the house. Excessive power wastes money and energy; The power is too small to meet the heating requirements. Two conditions must be met to meet the demand for electricity: heating and sanitary hot water. In Beijing, the heating rate of wall-hung boiler is calculated as per square meter 1.20 W, and the power of sanitary hot water needs to be above 10 L/min (△t=30℃) to meet the use requirements. Generally speaking, wall-hung boilers with power above 20kW can basically meet the requirements.

The third point: see if the service is guaranteed. The service life of imported original wall-hung boilers is generally more than 15 years. Besides the two-year warranty, there is at least 13 years of charged maintenance. In the long years of 13, if there is no good service guarantee, the consequences will be unimaginable. Therefore, to be on the safe side, when you are sure that the project you want to buy belongs to wall-hung boiler heating, you must make a detailed investigation on the company scale, warehouse accessories, maintenance site, user feedback and so on under the premise of understanding its brand.

Only when used properly can it be safe and efficient.

Any product, as long as it is used properly, can guarantee its life and be used better by me. Of course, the wall-hung boiler is no exception.

When using, first pay attention to the pressure must not be too high. 1.2 ~ 1.5 is the most suitable range. If it exceeds, it will shorten the service life of the seal, and if it is too small, it will not start. The solution is to open the exhaust valve to drain water and open the water inlet switch to add water.

Secondly, taking a bath and washing dishes uses the hot water function of the cooker. Everyone is used to adding some cold water when the water is hot. Actually, this is a misunderstanding. The hot water in the furnace is not directly heated, so adding cold water will change the pressure in the circulating ironing system. This pressure change will be transmitted to the corresponding circuit and chip by the induction equipment, and the furnace will rearrange the operation mode of each equipment according to the preselected temperature, so repeated operation will accelerate the aging of the equipment. How many degrees of water temperature should be set according to the actual situation.

Thirdly, if it is found that the water output of the faucet is getting smaller and smaller, it is necessary to remove the filter screen of the faucet to remove impurities. Of course, even if used properly, there is the possibility of problems. When there is a problem with the owner's own wall-hung boiler, many people think that they should find a developer or a property company to deal with it. This will not only easily lead to disputes with developers or property companies, but also more easily aggravate the contradictions between the two sides. I would like to remind you that if there is a problem with your wall-hung boiler, you really need to find the manufacturer and find the corresponding unit to solve it according to the maintenance card and insurance policy provided by the manufacturer.
