Generally speaking, PE-RT, PE-XA, PE-XB, PE-XC and Pb pipes are used for household floor heating pipes. These pipes can be used as floor heating pipes at reasonable temperature and water quality, and their service life can reach 50 years, so everyone can use them with confidence.
The floor heating pipe stipulates that the water temperature of the floor heating should not exceed 60 degrees. If the water temperature is set at 70-80 degrees, the service life of the floor heating pipe will be seriously shortened and the floor may be deformed. Secondly, it is also related to the pH of water quality. A water softener can be installed indoors to supplement softened water and purified water for the heating system.
Secondly, it is related to the water pressure of the floor heating pipeline. If the pressure is too high, it will affect the service life of the floor heating pipeline. However, the household wall-hung boiler system generally has no pressure protection, which will not make the system pressure too high. The main reason is that the pressure must not be too high when the system measures the pressure. When cleaning the floor heating pipeline in the later stage, high pressure washing cannot be used.
Extended data:
Floor heating is short for radiant floor heating, and English is radiant floor heating. It takes the whole floor as the radiator, heats the whole floor evenly through the heat medium in the radiant layer of the floor, and conducts it from bottom to top by using the law that the floor itself accumulates heat and radiates upwards, thus achieving the purpose of heating.
Water heating system refers to a heating method that heats water to a certain temperature, transports it to the water pipe cooling network under the floor, and realizes the heating purpose through floor heating.
The low-temperature geothermal medium forms a gradually decreasing temperature gradient from the sole of the foot to the head indoors, which gives people the comfort of warming their feet and cooling their heads. Radiant floor heating conforms to the fitness theory of "warm feet and cool roof" in traditional Chinese medicine. It is the most comfortable heating method at present and a symbol of modern life quality.
As far as heat medium is concerned, it can be divided into two categories: liquid circulation system and electric floor heating, and as far as pavement structure is concerned, it can be divided into wet floor heating and dry floor heating. Dry floor heating does not need to backfill peas (ultra-thin). From the surface decoration materials, it can be divided into floor floor heating and floor tile floor heating; Functionally divided into ordinary floor heating and far infrared floor heating.
