How is the installation of a warm water floor? Let's understand this issue in order.
To begin with it is necessary to be engaged in preparation of a surface. It is important to make it smooth, clean and smooth. The difference in the thickness of the pouring layer can have a strong enough effect on the efficiency of the entire system. The device of a warm water floor is a heating system, including heating elements, in which the role of metal pipes with a diameter of 20 millimeters, located on the surface of the floor in a special way. It also includes an installation cabinet, pipelines: supply and discharge, collectors, water heating boiler, water pump.
The device of a warm water floor is made so. After the preparation of the foundation, the waterproofing, which is made in the form of a thin film, should be laid on it. At a width of 100 millimeters on the wall surface, a damper tape is applied, which takes on the role of a compensator designed for thermal expansion of a cement-sand screed. On it it is necessary to lay the plates performing heat-insulation function, and after them the reinforcing mesh, to which the heating pipe will be attached. It is fastened in steps of a meter. The heating pipe is laid in a spiral or parallel. A more successful option is considered a spiral method, since the supply and discharge pipes are in this case placed side by side, thereby compensating for heat losses. Pipes are stacked in steps of 10-30 millimeters, and the distance to the wall should exceed 7 centimeters.
The device of a warm water floor begins with the fact that a collector cabinet is fixed to the wall . It should be placed in the same room where the floors are installed. The cabinet houses the supply and discharge manifolds. Next, you can proceed to install a heating pipeline, the ends of which must be connected to the collectors. In addition, pipes must be connected to the manifolds, as well as valves intended for venting.
The water heating of the floors is mounted as follows. One end of the pipeline is fixed to the supply manifold, after which the first circuit must be laid. It should not have intermediate connections. This is the only way to ensure the reliability of the system. The return pipe is connected to the second end of the pipe. When the heating pipeline is laid, it is possible to fill the surface with a sand-cement mix. Floors are recommended to be poured with mixtures that are sold in specialized stores. When the composition dries, start laying a parquet board, tile or laminate. By means of a special valve, it is possible to adjust the temperature of the warm floors. Usually this regulator is installed in front of the collector.
Naturally, there are other types of warm floors, but this can be considered the most successful option. It should be said that its installation is a rather laborious operation, but the result is worth it.
