The service life of the floor heating system is mainly the service life of the buried pipe, because the above-ground part can be replaced, therefore, the floor heating selection pipe is the key to the service life. The pipes used in the floor heating system are generally plastic aluminum pipes, PE-RT (high temperature resistant polyethylene pipes), PEX (a, b, c) (cross-linked polyethylene pipes), Pb (polybutene pipes) pipes, etc. PE-RT is divided into first-generation PE-RT and second-generation PE-RT; PE-X pipes are divided into peroxide cross-linked polyethylene pipes (PE-Xa) and silane cross-linked polyethylene pipes (PE-Xa) according to the cross-linking method. PE-Xb), electron beam cross-linked polyethylene pipe (PE-Xc) and azo cross-linked polyethylene pipe (PE-Xd).
The use of the first generation PE-RT is below 65 degrees, and the working pressure does not exceed 0.4Mpa; the long-term working temperature of the second generation PE-RT and PE-X can be within the range of -40 degrees to 85 degrees. PB pipes can be used at 95 degrees, except for floor heating, only PB pipes can be used for radiator heating, but PB pipes are expensive and only used for high-end projects. PE-RT and PE-Xb are the earliest, most widely used and most mature floor heating pipes in the floor heating system. They are safe, environmentally friendly and healthy. They are designed and used within the normal product standard range, with an actual life span of more than long-term durability according to standards. They are the most environmentally friendly. floor heating pipes.
It can be considered that the floor heating system is basically equivalent to the life of the building.
