Roof heating - how to make

Sossels and drifts formed on the roof of winter are one of the urgent problems of property owners. Snow covers can lead to premature damage to the roof, and any of numerous icicles can fall straight on the head. For many years, this problem was solved by mechanical confusion of icicles and clearing snow, but now the installation of roof and drainage systems is especially popular.

Installation of electric heating systems of the roof and drainage is the most effective method in the fight against icing and snow, it does not just eliminate them, and does not allow them to appear in principle. In order to choose the right system - you need to clearly imagine the principle of its work. The cheapest method of heating will be laying around the perimeter of the roof of the resistive power cable, which is a single or two-housing cable in isolation - LTO, DEFROST SNOW NEXANS TXLP / 1 and so on. Its main disadvantage is the absence of power adjustment. If this option does not suit you - use self-regulating wires, for example, ELTHERM-15 ELSR or THERMOVAL ELSR 15. Due to a specially polymer matrix located between copper veins, such a cable has the ability to adjust the resistance depending on the ambient temperature and the single surface area. The main drawback is high cost.

After you decide on the cable and purchase it, you can proceed to the direct installation of the system. To begin with, connect the cable in the section whose area will be enough to close the entire perimeter of the roof of your home. Use special clamps to connect the cable to each other. How everything will be connected - put the cable on the roof with a zigzago-like way and securely secure it with a special fastener.

To calculate the number of turns and their valleys, this formula is useful to you:

The next step is the installation of the heating system of the waterproof. The heating cable is placed inside the gutter along its entire length. Use special brackets as fasteners, which can be purchased with a cable. The distance between them may vary from 30 to 50 centimeters.

After the installation of the heating cable is complete, engage in the installation of the distribution network. To do this, at the same distances from each other, place the junction boxes, which will then be connected to the network. If you use a self-regulating cable, install precipitation, moisture and temperature sensors. The precipitate sensor mount on the upper part of the building using M-shaped brackets in a place convenient for maintenance. The temperature sensor must be hidden from sunlight and exhaust ventilation. The final step is to connect only one chain and trial launch.

By producing roof heating installation, never forget about the safety requirements for the work carried out at the height and the associated with electricity. When they comply with and clearly follow the instructions outlined above, you will be able to fulfill and save on the payment of specialized brigades to pay for the work of specialized brigades.
