Leaking roof in the spring associated with de-icing runoff to 90% of cases.
Clogged gutters and drains the ice during a thaw blocking the outflow of water from the roof.
Consequences - leaking roofs, facades of destruction on the upper floors of buildings.
The greatest danger posed to leaking roofs with curved inner corners, towers, attics and other decorative architectural elements.
Cable heating gutters and drainage solves this problem and increases the lifetime of the roof, fixing brackets downpipes and gutters, reducing the mechanical stress caused by ice formation.
Heating cable is suitable for the following engineering areas: gutters
rainwater hopper and the area around them
valley - seam roof sections
catchment and drainage trays
eaves of roofs
Installation of cable heating gutters and drainage
Heating cable system consists of a drain the heating section (a self-regulating heating cable), the thermostat, control panel with automatic protection systems and power distribution.
When installing heating cable system drainage is important that the cable was in the place where the water flows. The complexity of installation is that, in Gutter system extra holes are not allowed, so the cable inside the gutter is fixed in a special way. The cable is laid in the drain pipes, roof gutters and valleys in the form of the plume. In the storm sewer system, heating cables are routed below the soil freezing. Necessary to ensure the outflow of water in all parts of drainage system.
Linear power heating cables in gutters should be 60-70 W / m (minimum of 20-40 W / m). If the channel is wider 150 mm, for normal weather conditions, taking the estimated capacity of 200 W/m2.
In the case of a cold roof is sufficient to lay cables only in the drain system.
In the case of a warm roof falls further cable loops along the edge of the roof width of 0.3 - 0.5 m, with a specific power of 200 - 250 W/m2.
Heating pipes. In private homes and businesses.
How good would not be a thermal insulation pipe to completely eliminate the heat loss is not.
Heating pipes and piping systems with heating cable to prevent such problems.
Principle of operation
Unlike conventional electric cables having low resistance, the heating cables are themselves load but the load is evenly distributed. Voltage applied to the heating cable, falls into it.
In order to recover heat losses along the pipeline or within the heating cable is laid, selected so that the power per unit length greater than or equal to the heat loss per meter of pipe.
With the right calculations and installation heat does not cause overheating of the cable or the heated object.
For heating pipe from freezing are two basic types of heating cables: resistive and self-regulating.
Self-regulating cable is laid on the surface or inside pipes efficiently and effectively prevents them from freezing. To save energy, set the thermostat turns off the cable at a certain temperature.
The thermostat is usually set in a supposedly very cold place pipe.
Self-regulating cable can be used to maintain the temperature to 120 degrees. Centigrade. This method of heating pipes are widely used in various industrial processes and domestic, including heating of sewage pipes and tanks.
