Heating downpipes - some luxury as savings

What is the system?

de-icing gutters - a system which ensures the prevention of the formation of ice in the cooler times of the year on the edges of roofs and gutters gutter.Such a system not only protects bystanders from potential injury, but also reduces the cost of maintenance of buildings.De-icing consists of the following elements:

• heating cable;
• power distribution system;
• Automatic control program;
• Elements of fasteners.

heating cable melts all precipitation from solid to liquid state.This process takes place prior to their complete withdrawal from the runoff.energy distribution system, in turn, used to connect cables and control system.It includes power cables, fasteners and junction box.Automatic control system - a case, in which the enclosed protective launcher equipment, regulators with temperature sensors, rainfall and water.

Important!If you faint in the electrical machines may have to replace them.

Heating downpipes of various roofing

As you know, there are two types of roofing: cold and warm.Depending on the type and selected anti-icing system drainpipes.To cool roofs are roofs with attic temperature close to the temperature of the outside air, and the roof with an insulated cover.The problem with the appearance of icicles for her actual thaw.To protect the system from freezing, the heating cable is installed in the pipe and the roof gutter.Design capacity should be around 30-50 watts / meter of pipe length.This capacity is sufficient to insulate runoff.

Warm roof - a roof with poorly insulated that the heat loss is zero temperature in the attic when the roof is covered with a layer of snow.With such insulation melted snow fall in the gutter, and there are frozen.Therefore, for this type of roof is necessary to additionally install a heating cable for heating it to the edge.Also, such an additional cable is installed in areas where heavy rainfall, which give a serious load on the roof.

Note!The type of roof will depend on the method of heating the drain, so it is better in this regard to consult a specialist.

Deicing Systems

Depending on the specific tasks that are put before the system is used and the different heating cables.They exist two types: resistive and self-regulating.Resistive Cable is one-and two-wire and is highly durable and comparative cheapness.With it is heated drain pipes, flat roofs and concrete drainage trays.

In these cables the heating element acts lived.The disadvantages of this method include fixed gutter heating cable length, because of what difficulties may arise in the design and installation.Self-regulating cable characterized in that it changes depending on heat conditions.The heat source there is a matrix that produce heat.Located

this matrix between the two conductors, conducting current.Power consumption of the system varies with the rainfall and air temperature.The advantage of the cable is possible to design a de-icing system of drains, because it can be freely cut to the required length.They do not overheat, and are not afraid of dirt and moisture.

Note! Self-regulating cable can be installed in both warm and cold in the roof.
