Rehau water underfloor heating product description and installation steps
Underfloor heating is gaining popularity among residents of private homes, becoming a full-fledged alternative to the traditional radiator heating. Installation of such a heating system is very complicated. It requires not only certain knowledge and skills, but also the use of quality materials that can last more than a decade.
For this reason, experienced installers, who have already once faced problems due to improperly selected materials or errors during the installation of the system, prefer to purchase products from trusted manufacturers. One such manufacturer is the company REHAU, which began its work in the middle of the last century.

Accessories for Rehau underfloor heating
A well-known German company for the production of polyethylene pipes Rehau is also engaged in the manufacture of additional devices that are designed for heating systems. These products include accessories for underfloor heating. The basis for the line is the so-called mat (plate, which has fixing ribs). The size of such a plate can be different (depending on the size of the room). It consists of elements which are connected to each other and form a continuous plane. The board is made of expanded polystyrene. This elastic material is particularly durable, and not afraid of temperature changes. Some models have thermal insulation, which reflects the heat energy, and directs it into the room, not allowing it to the floor. If such a screen is not available, then a special foil, which is laid under the mat, comes in handy. The entire system is designed for installation under the decorative layer of the floor (filling screed and laying tiles). Temperature spreading to the walls is blocked by profiled wall insulation.
Rehau underfloor heating accessories are compatible with pipes from the same manufacturer. In recent years this system has become increasingly popular among consumers around the world. The peculiarity of underfloor heating is that it does not work through convection. That is, the heat that rises does not push the cold air down to the floor. Thanks to that, it is cooler upstairs than downstairs. With standard heating, the floor space is not heated up, which leads to cold feet in the house. That’s why you have to turn on the heating more. As a result, the top of the room accumulates hot air, which makes it difficult to breathe, and the bottom is still cold. The Rehau underfloor heating system eliminates this problem. All visitors keep their feet warm and breathe easily because the room is filled with fresh air. This system has several advantages over its electric counterpart. Firstly, no need to think through additional protection against electric shock. Secondly, the water underfloor heating has a high heat output. Thirdly, such a floor heats up faster, which significantly reduces the cost of heating. With the help of presented devices for quality installation of the main line even a novice can cope with the task.
Pipe Rehau Rautherm S. floor heating (Germany)
RAUTHERM S pipes are designed for surface heating systems. They are made of well-proven material PE-Xa in Russia and meet the highest requirements of durability and reliability:
resistance to high temperatures and pressure resistance to corrosion and scaling resistance to low temperatures (up to.50 ° C), installation to.10 ° C high chemical resistance (absolute resistance to antifreeze in all concentrations) high resistance to abrasion and mechanical stress memory form. the ability to restore the original shape, lost through mechanical stress, by heating up to 130 ° C with full retention of properties.
Installation with REHAU Varionova clamping mats ensures reliable fixing of the REHAU RAUTHERM S pipes and saves time. The entire surface area is assembled from standard blocks, which are overlapped along the connecting line and snapped together. No waste is left behind. Each successive row continues the previous one. Pipes from the RAUTHERM S program have, in comparison to RAUTITAN pink pipes, a thinner wall, which allowed:
to increase the heat output of the pipeline by 6% with the same outside diameter by reducing the thermal resistance and increasing the inner surface that absorbs heat from the coolant (this value is highly dependent on the share of the thermal resistance of the pipeline material in the total thermal resistance of the screed or plaster layer): to increase the capacity of the pipeline by 20% by increasing the live section, and therefore the heat output by another 20%. reduce specific hydraulic losses by 15% increase elasticity of pipelines and reduce the minimum bend radius to 5 diameters, compared with 8 diameters for RAUTITAN pink, simplifying laying.
In addition to the standard diameters 17 x 2,0; 20 x 2,0; 25 x 2,3; 32 x 2,9, the program RAUTHERM S added small diameter pipes 10 x 1,1; 14 x 1,3
Rehau pipe for underfloor heating: pros and cons
The German company Rehau specializes in the manufacture of various products for the construction industry. Russian representation of this manufacturer appeared in the 90s of the last century. Creation of pipes for underfloor heating is one of the main directions of the company’s activity. These products have both pluses and minuses, but the advantages are much more. for this reason the Rehau pipes have gained popularity among consumers.
Pipe for underfloor heating Rehau Rautherm S

And thanks to the flexible PE-XA material RAUTHERM S can also be installed in sub-zero temperatures. The scope of application of these pipes are panel radiated heating or cooling systems, including underfloor and wall heating systems.
The connection of pipes RAUTHERM S is made by means of couplings and sliding sleeves RAUTHERM S17 and S20, which are also produced by Rehau. The pipes can be attached by means of various fastening elements, such as: harpoon clamps, RAUFIX fastening system, fixation clamps for the reinforcement grid or by means of mats with Varionova fastening technology. Thanks to this range of fastening systems, the method of laying pipes can be made in the form of a coil, coil or double coil. In addition, Rehau accessories greatly simplify the installation of RAUTHERM S pipes, saving you time and effort.
Temperature characteristics also reach the limits of all representatives of this class. the pipe demonstrates excellent stable operation at a water temperature of 90 degrees. These values are due to the qualitatively revised molecular structure of the equipment. cross-linked polyethylene PE-Xa constitutes the inner core of Rautherm S. Thanks to the unique properties of this material the pipe does not require additional protective devices and is very easy to build. When repairing, it is easily spread over the floor and then covered with a layer of the desired floor covering.
Simple and very effective design allows you to expand the scope of application of underfloor heating. The technology can be used in any building solutions and can easily be combined with other ideas. High heat output allows the pipe to be used as the primary heating option in the house. Comfort of living is easily provided by distribution of these pipes throughout the living area, next to the windows you can install Rehau in the walls, which will add heat to a cold room.
The high standards of the manufacturer give a long-term guarantee for each heating system. With Rehau pipes heating efficiency of the whole house will increase and the cost of it will increase slightly. The small size of the pipes makes it possible to insulate even small rooms, you can also spread the floor heating in small areas of the rooms, thereby allocating an area for a child’s play or an area free of carpets. The great practicality of the Rautherm S pipe opens up the prospect of combining floor heating with other construction technologies. floor screed, laying solid tiles. Accompanying pipes manufacturer supplies the necessary accessories sleeves and fixing screws, which are required for the proper fixation of the floor heating.
