Nexans warm floor: features of the device and installation

The French corporation Nexans has been manufacturing cable products since 1897, the list of products includes floor heating systems. Factories of this company are located in different countries of the world, using high-quality equipment and the latest technology. Every year the product will be improved, making the Nexans underfloor heating systems one of the most popular on the market.

The company cares about the safety and durability of its products. She developed and put into operation the splice-free coupling system. With the help of it, the most frequent causes of damage to the heated floor in the joints of the heating and nutrient cable ends were minimized: because of the temperature difference, the spike could not stand.

The heating system includes several components to ensure its smooth operation and maintain the desired room temperature without any problems. It includes:

• A heating element. It is a heating cable of two types: self-regulating and resistive, with a heating core inside. The latter is divided into single and strong.

• Thermostat This is the device that is responsible for managing the warm floor. There are mechanical and programmable regulators. There are significant differences between them, the ability to program work reduces the cost of electricity, because the system itself recognizes what temperature needs to be set, including if necessary to transfer them to an economical mode. Modern technologies make it possible to control the operation of the system remotely and immediately in several rooms.
• Thermal sensor. Detects and transmits information about the temperature level in the room. It is embedded between the turns inside the floor and in the body of the thermostat.

In the product catalogs are presented various types of cable sets.The company offers its own set of products, which is immediately ready for installation in different types of premises with different types of flooring, laid over the warm floor.

• For the kitchen, hallway, rooms or bathrooms the company offers set of single and twin TXLP cables with a capacity of 17 W / m. It is ideally suited as the main heating of the room, as well as additional, if, for example, there is a water heating system. It is better to use when there is an opportunity to make a concrete screed with a thickness of more than 2.5-3 cm. The connection type is ductless, the grounding conductor is made of copper, there is a protective aluminum tube, the insulation is made of embroidered polyethylene, the outer shell is PVC. It is controlled by the thermostat. The maximum temperature of the outer shell is 65 degrees Celsius.

• Another option is thin floor system MILLIMAT 150 W / m. If it is not possible to raise the floor level to the required height, then this is the best choice. Thermomats are made of a twin-core heating cable on a self-adhesive mesh of reinforced plastic. The cable is laid in a zigzag in steps of 10 cm.The insulation is made of PTFE, the outer shell is made of PVC, the connection is ductless SPLICE. Such mats do not require preparation for installation, they can be glued to the subfloor, including without removing the old flooring. From above put a small layer of tile glue, and everything is ready for installation and a new flooring. The maximum temperature of the outer shell is 100 degrees Celsius.

• Under wooden floors are recommended heating cable sets TXLP, it is single-core with a power of 10 W / m, the high thermal conductivity of wooden floors allows the use of less power of the heated floor.

• Heated floor on the balcony or loggia. It will be convenient to use set of two-core heating cable DEFROST TWIN 28 W / m or single-core TXLP / 1R heating cable with 28 W / m. It is laid with a uniform pitch under the screed of concrete. Applied specifically as a snow melting system. These cables have a ductless connection, an outer sheath of PVC, it protects it from external factors, water and ultraviolet, the same shielded aluminum winding is directed to the same.As the grounding cable is used from eight-tinned tinned copper.

Nexans warm floor will serve for a long time and smoothly, if you follow all the rules of its installation.

The main rule is not to engage in independent activities, but to strictly follow the instructions that are attached to each set of heating cables:

• Before installing a floor heating system, prepare a flat floor covering, preferably a concrete screed, 3-5 cm thick.
• Thermal insulation. To avoid heat loss, lay the foil on one side of the material on the floor, leaving small areas of the screed visible.
• It is necessary to lay the cable in increments of 10 to 25 mm, usually on it are shown the places of bending.

• Be sure to make a ground connection. If power is insufficient, a stabilizer or magnetic starter is needed.
• Thermal sensor should be connected before laying cables. To avoid the ingress of dirt and dust during further work, cover it with polyethylene or remove it before the end of the work.
• Check the flooring before the final casting of the screed.
• It can be switched on after after pouring no earlier than 28 days, in the case of using thermomats, not earlier than in a week.

The unique connection system is not the only plus of Nexans underfloor heating; among the advantages of this type of electrical heating are:

• It is compatible with your favorite types of flooring: concrete, wood, tiled, with floors covered with linoleum or PVC tiles.
• Able to replace the main heating system.
• Relatively low energy costs, especially with the use of a programmable thermal sensor.
• Possibility of installation in any room.
• Such heating retains humidity in the room and is one of the most environmentally friendly.
• Convenience and ease of installation, even with your own hands.

• Product quality. For protection against overheating, mechanical and chemical effects, water and ultraviolet use high-quality raw materials, such as aluminum screen, PVC sheath, grounding from copper.
• Shelf life up to 60 years.

Buyers respond positively to Nexans products, pointing out only the high cost of the product. Self-adhesive mats are most popular due to ease of installation. Long-term use does not affect the work, marriage and failure practically does not occur.Heating is uniform, does not affect the quality of the floor covering, suitable for any premises and even under floor heating by the pool.
