One of the most affordable anti -icing systems is a system based on heating cables. Its proper installation, taking into account the design of the roof, completely eliminates the possibility of the formation of ice. The undoubted advantage of this system is its relatively low cost, work efficiency and small energy consumption. As a rule, at low temperatures (from -18 ° C), the operation of anti -icing systems is not needed, it can even harm, since solar heat is not enough to melt snow, and the roof of its own heat is not enough to form an ice crust.
In order to ensure rapid melting and removal of melt water from the roof, great electricity is required, but all efforts will be in vain, if you do not think through the drains. The power of the heating cables of the system can be adjusted, the only thing must be remembered that the system is ineffective outside the power boundaries: if the power is less than the lower limit, then the system does not work, if higher, then the electric power is consumed ineffectively, and the quality of its operation does not improve. The main thing is to remember that when installing a system of anti -icing, you should adhere to the requirements of the fire — and electrical safety.
