From the article you will learn what is cable heating of roofs and gutters using anti-icing systems, the main components, installation rules, types and structures of cables, the scheme and principle of laying, how to connect, control and protection equipment, ready-made solutions and much more.

The main tasks of anti-icing systems

Anti-icing systems – a set of devices, the task of which is to prevent the formation of frost on the cornices, as well as ice plugs in drains for draining water.

Timely and correct installation of heating of the roof and gutters allows you to protect building structures from dangerous contact with water, snow blockages or the formation of icicles.

The main difficulty is the correct arrangement of the system, because the quality of heating and the efficiency of the system as a whole depend on it.

What is a roof and gutter heating system

An anti-icing system is also called a cable heating system for gutters and roofs.

Its work is based on laying a group of cables that heat up and help thaw the snow, as well as protect against the formation of ice on the roof and in the building’s drainpipe.

The peculiarity of the system lies in the possibility of its inclusion in the most dangerous periods, when the probability of water freezing on the roof is most likely.

It is known that the main cause of damage to roofs, drains and gutters is ice, which accumulates on the surface and carries its destructive effect.

With proper installation, the cable system eliminates the fall of icicles near the house, which allows it to be attributed to one of the elements of the building’s security system.

In 2004, the Moscow Committee for Architecture published a document that provided recommendations on the arrangement of such systems on the roofs of buildings equipped with internal and external drains. Such recommendations applied to both residential buildings and industrial facilities.

Today heating of a roof and drains is in the greatest demand in Moscow and St. Petersburg. In these cities, anti-icing systems are installed on several thousand buildings, and this number is only growing.

During the period of installation work, companies that specialize in this work have managed to accumulate considerable experience and eliminate serious mistakes that were made before.

With proper design and compliance with the installation rules, the cable heating system eliminates the appearance of ice on the surface and guarantees the timely removal of water through the devices intended for this.

Due to this, the service life of the roof is significantly increased, “punching” and deformation of the gutters are excluded.

In addition, the risk of icicles falling on people passing by buildings is reduced.

Causes of roof icing

Experts identify two reasons for the formation of ice on the roof of structures:

Incorrect installation and low thermal insulation of the roof, which leads to high heat losses. As a result, even at temperatures below zero, snow melts, followed by water runoff into drains and the formation of icicles. The best solution is to insulate the roof by installing a cable heating system. This option is effective, but does not eliminate the main cause of icing. On the other hand, the installation of an anti-icing system allows you to save money and avoid the need for restoration work at sub-zero temperatures outside.
Temperature fluctuations throughout the day. Even with a properly designed project and proper roof insulation, under the action of sunlight, snow melts even at sub-zero temperatures. As a result, the melted water is directed to the frozen drains, where it turns into ice. As the weather gets colder, things only get worse.

How frost affects the roof and roofing material?

If the angle of inclination of the roof is less than 45 degrees, in winter a “cap” of snow mass forms on it.

In some cases, the weight of snow can reach 100 kg per square meter. The load increases even more if the roof has a slope of 30 degrees.

In such cases, deformation of the rafters under the weight of snow is possible. To avoid this problem, it is important to periodically clear the roof of snow and remove icicles. In solving this issue, heating of the roof and gutters helps.

If you save on an anti-icing system, the consequences can be as follows:

Roof deformation. During the period of snow melting, the ice crust that forms on the surface is heated from below, moves and damages the roofing material. Subsequently, corrosion processes begin with these scratches.
Drainage damage. Weather conditions are unpredictable. In nature, there are situations when, after a short thaw, frost comes again. As a result, the water accumulated in the drains freezes, which leads to deformation or rupture of these systems.
Icicle collapse, snow mass gathering. If you do not provide for the heating of the roof and gutters, it is impossible to predict the time of fall of the accumulated mass of snow or icicles. As a result, there is a high risk of injury to passing people, including damage that is not comparable to life.

What are the types of roofs?

Taking into account the thermal regime, all roofs can be divided into several types:

Cold roof. The peculiarity of such a roof is the small heat loss that occurs through the ceilings in the upper part. Sometimes in such roofs there is a space that is well ventilated. Snow melting is observed only under the action of sunlight at a temperature of 5 degrees below zero. For this type of roof, a low-power anti-icing system is sufficient.
“Warm” roof. This design is characterized by poor insulation, which leads to the melting of snow on the surface even at low temperatures. As a result, the melted water flows down to the drains, where it freezes and clogs the holes. In addition, icicles appear, which at any moment can break down and injure passers-by. The lower melting temperature is 10 degrees below zero. “Warm” roofs are provided on various types of buildings – residential and administrative. Mostly they are mounted in old houses. To avoid problems, it is recommended to install a higher capacity anti-icing system (when compared with a cold type roof).
Hot roof. As in the previous case, there is poor insulation here, as well as the presence of an attic for technical purposes. In such rooms under the roof, as a rule, heating or other systems are installed. The disadvantage of such a roof is that snow melting occurs even in severe frosts (below -10 degrees Celsius).

The heating system of the roof and gutters will get rid of the problem, but its installation is associated with many difficulties, and its operation is associated with high costs of electrical energy.

For this reason, the work is best done in several stages. First, the amount of “extraneous” heat is reduced by insulating the upper floors, and then an anti-icing system is installed.

If there are heating systems under the roof, they must be additionally insulated.

The main components of the anti-icing system

The device for heating the roof and drain consists of the following elements:

One or more heating cable branches. The laying pattern is determined taking into account the type of roof structure required, the level of complexity of the surface, and the presence or absence of a structure for draining water.

Electrical (power) cable for powering the heating element from a 220 or 380 Volt network.
Protective equipment. This refers to a device that will turn off one circuit or the entire system when leaks exceed 30 mA, as well as in case of exceeding the rated current more than the permissible load current.
Control equipment. Modern anti-icing systems start automatically and operate at temperatures from +5 to -15 degrees Celsius. If desired, you can use the semi-automatic mode. The advantage of the control equipment is that it quickly responds to signals from temperature and humidity sensors. If necessary, the operating temperature range can be adjusted according to weather conditions.

General installation rules

Before installing the icing system, it is important to draw up a project in advance, and then proceed with the installation work.

Documentation should take into account the following points:

PUE requirements;
Recommendations of the manufacturer of the system and its elements;
Decree on the implementation of fire prevention measures;
Other documents.

The best results when installing an anti-icing system can be obtained by observing the following rules:

Work on a fine day when precipitation is not expected;
The arrangement of the icing system must be carried out only at positive temperatures;
The area intended for laying the heating element must be clean and dry.

Remember that most of the sealants and adhesives that are used during the installation process work at positive temperatures.

The same conditions apply to various models of power and heating cables.

During the installation process, consider a number of recommendations:

For the greatest efficiency of the anti-icing system, work in the warm season.
Installation of roof heating and gutters is best done on roofs where an organized drainage system is provided.
The task of such a system is to prevent the freezing of melt water and to ensure the discharge of accumulated moisture into the drainage system.
Before starting work, the roof surface must be cleaned and dried.

The ideal option is when the anti-icing system is designed at the design stage of the building.

In this case, it is worth considering in advance the path of laying the power cable from the roof structure node to the energy distribution point.

If a heating system for the roof and gutters has not been provided, during the construction process it is required to install horizontal and vertical embedded parts.

When arranging the anti-icing circuit, the cable power supply should be closed using rigid boxes or corrugated channels.

Types and structures of heating cables

When arranging the circuits, two types of heating products are used, the total power of which is equal to or greater than 20 W per square meter.

Laying, as a rule, is carried out in an open way, so the cables must have a reliable sheath that protects against UV rays and atmospheric moisture.

During operation, the heating elements should not touch materials containing bitumen – euro-roofing material, shingles and other coatings. If the laying is carried out on a bituminous roof, the cable sheath must be made using a photopolymer.

A big plus is the presence of an armored braid that will protect the product from mechanical damage.

On sale you can find power cables that are made in the form of a spring and exclude rupture during expansion or physical impact.

Resistive cable – types and structure

When installing the anti-icing system, two types of resistive cables can be used – one and two-core.

In general, the product is a metal conductive core that generates heat, a shielded braid, insulation, and an outer PVC sheath.

Let’s take a closer look at the types:

Resistive cables allow you to save on heating the roof and gutters at the stage of purchasing the material. As for installation, it is more expensive, because a longer length is required. The number of fasteners is also increasing.

The disadvantage of resistive cables is that they have a fixed length of sections, while the main elements of the roof, trays and gutters are made in various lengths.

The problem can be solved in only one way – by selecting products with different resistance. In addition, the operating conditions of different sections of the cable may vary, which is why roof heating is not always effective.

Self-regulating cable – types, structure and typical layouts

Unlike a resistive product, a self-regulating cable adjusts the resistance at each section or along the entire length. If desired, it can be cut into pieces of suitable length.

Structurally, a self-regulating cable is an electric-type tape heater, inside of which there are parallel conductors.

The latter are separated by a semiconductor-type heat-generating polymer matrix.

In turn, the conductive material of the central part plays the role of a heating element, which allows you to cut the cable in any necessary place.

As a result, the appearance of cold areas is eliminated and heat production is regulated taking into account the characteristics of the environment.

In fact, each section of a self-regulating product quickly adapts to external conditions.

This type of cable can be of two types – with or without a copper braid. Otherwise, the structural elements are identical:

Copper conductors;
Self-adjusting matrix;
Polyolefin shell;
Outer shell polyolefin type.

As noted above, resistive cable costs less, but electricity costs are higher.

At the same time, the use of a self-regulating “competitor” allows you to reduce costs, which is explained by competent adjustment to weather conditions.

Due to the design features, such a cable can heat up differently in different parts of the roof – in the shade or on the illuminated side.

The ability to cut anywhere eliminates a large number of surpluses.

Definition of heating zones

When determining the working areas and places for laying the cable for heating gutters and roofs, the efficiency of the flow of melted water is taken into account.

To achieve the greatest efficiency, the cable is laid in downpipes, gutters and other places where there is a high risk of ice formation.

The total length of the anti-icing system is determined by summing up the main elements of the roof that need to be heated.

With a steep slope, when there is a risk of a mass of snow and ice coming off, it is required to mount a snow retention system.

In such situations, it is worth laying the cable in the area between the protective device and the edge of the roof. The height of the snake is selected taking into account the width of the eaves.

If there is no risk of collapse, only drains and gutters can be heated. Depending on the diameter of the latter, the power and quantity of the self-regulating cable is selected.

Scheme and features of laying heating cables

The choice of a scheme for laying heating elements for roofs and gutters is made taking into account the angle of inclination of the roof slopes, as well as its configuration.

The greater the slope and the simpler the shape, the fewer meters of the product will be required to equip the surface.

Principles of laying and fixing the heating cable

Anti-icing systems, as a rule, are concentrated in places of the greatest accumulation of winter precipitation and ice formation.

These should include:

Sloping roof eaves. If the angle of inclination of the roof is less than 30 degrees, the heating system is laid at the bottom and has the shape of a snake. For greater efficiency, the entire cornice is covered in width and another 30 cm is captured above the conditional line of the building wall. If the angle of inclination of the roof does not reach 12 degrees, the installation of heating is carried out in areas adjacent to the drain funnels.
Valleys (grooves). These roof elements are equipped with a heating cable for 30% of the length. The product is laid in the form of a long loop, and the distance between the sides may vary depending on the type. For resistive cables with two cores, the distance is 40 cm, and with one – 10-12 cm.
Drainage poles. To heat this section, the heating cable is attached directly to the pipe and has the form of a loop fixed on the walls of the drain. When water is discharged into a special sewer, the plant is produced to a freezing depth. If it is not possible to heat the sewer, it is advisable to close it altogether for the period of cold weather.
Funnels of the external drain of the wall. The installation of an anti-icing system is only necessary here if it is located separately, outside the gutter.
Funnels for collecting water on flat roofs. During installation, the cable near the funnels must cover an area of 50 cm on each side. Inside the funnel, the product is wound up in the form of a loop to the level where the warm room in the building begins.
Parapets. To achieve the desired effect, it is enough to lay one branch of the cable along the product.
Water cannons on flat roofs. Here, the heating cable of the anti-icing system is laid at the bottom of the structures, also in adjacent areas of 1 sq. meter.
Roof connections. Here the principle is the same as in the case of parapets.
Droppers. Their heating is necessary depending on the design features. Arrangement of one or two branches is possible.
Gutters. The anti-icing system cable is laid in parallel rows. Similarly, the arrangement of the drainage trays of the internal drain used in the process of arranging the roof is carried out.

In a pitched roof, you can do without heating the cornices. If the angle of inclination is more than 45 degrees, the snow mass will be removed without additional help. In this case, the heating cable should only be laid in the elements of the drainage system.

If ice builds up near the roof windows, the heating filament is laid near them towards the drain.

If the building does not provide for a drainage system, the heating line goes through the drip and along the extreme part of the ramp.

Here, it is necessary to mount a device for retaining snow above the cable installation site and equipping a dropper on the eaves.

The fastening of the anti-icing system elements deserves special attention. Here you should adhere to the following rules:

The cable must be securely fastened so that it is directed along the flow of melt water. It is important that it fits snugly to the roof and does not sag in the air.
If a resistive cable is used during installation, it is forbidden to cross or touch its sections.
Fastening must be carried out in such a way as to exclude damage to the roof and the heating line itself.
The cable is fixed on the roof surface using the methods specified in the instructions for the product. It is important that the fastening does not violate the integrity of the coating.

Flat roof icing system

On a flat roof, the heating cable is laid along the perimeter of the water drain line.

In addition, the heating circuit must be led into an internal drain funnel about 40 cm or more (for an internal drain). If the trays are external, a dripping loop is made.

In places where the roof touches the parapet, laying is carried out near a receiving tray with a power of 60-80 W per “square” with access to the tray and laying in a pipe for water drainage.

Connecting the power cable

The anti-icing system is connected using a power cable to a single-phase or three-phase network.

When connected to a network with a voltage of 380V, phase imbalance is possible in the range of 10-15%. To avoid the problem, it is desirable to use anti-icing systems with a total power of up to 6 kW.

If this parameter is higher, the connection is made evenly to the three phases of a 3-phase circuit.

When choosing a cable section, it is worth focusing on the power consumption and the total length of the heating section. In turn, the power depends on the resistance of the branches and the length of the heating line.

During the installation process, it is important to take into account the regulations of the PUE. The power and heating cable must be combined in a junction box, instead of which a heat shrink sleeve can be used. The latter guarantees tightness at the joints.

The device of the heating system of the internal drain

The internal drain deserves special attention, the heating of which is carried out according to a separate scheme.

The structure includes a funnel roof, waterproofing, thermal insulation and mounting tape.

The elements of the system also include a temperature sensor, a heating section, a junction box, a power cable, a casing, a clamp and a rivet.

If the roof has a flat design and the drain funnels are built-in type, the heating cable is laid on the path of collecting water, as well as in areas near the funnels.

After that, it is discharged into the funnel and into the pipe until it enters the heated room.

If the product does not go through a warm area, the heating cable is lowered to the foundation of the structure or to the level of the blind area. In the presence of a drainage system, laying is carried out to the freezing depth.

Control and protection of the anti-icing system

The purpose of the control system is to create conditions for automatic or semi-automatic operation of heating the roof and gutters, and the protection system is to quickly eliminate emergency situations (short circuits, leaks or overloads) in the circuit.

Let’s consider these points in more detail.

Control equipment

The task of the control equipment is to activate the heating cables, as well as to turn off the power when the operating temperatures are exceeded.

Today, two types of equipment are used:

The first option is more affordable, but in regions with high humidity, a large error and ice may appear on the roof surface.

In this regard, the weather station is more sensitive and responds more accurately to changes in humidity. In addition, the greater accuracy of the weather station allows you to save money on electricity.

If the region is dominated by low humidity and the arrangement requires a low-power anti-icing system, a thermostat will suffice.

Interestingly, self-regulating cables are able to work without automatic control, thanks to the ability to independently regulate their power, taking into account the temperature outside and the presence of precipitation.

But it is still better to use special thermostats.

Here you can use the following devices:

Of the weather stations, IS-11 showed itself well, which is characterized by increased efficiency and does not require cleaning during operation.

Protection equipment

The control and protection panel for the roof and drain heating system includes the following elements:

Introductory circuit breaker;
Thermostat circuit breaker (weather station);
Magnetic switch;
UZO (30 mA);
Circuit breaker heating;
Alarm.

In more complex systems, a number of additional devices can be mounted, such as a time delay relay, a current transformer, controllers, a soft starter, and other systems.

The protection equipment must guarantee:

Protection of the supply circuit (single-phase or three-phase) against short circuit in the heating line, power cable or in any of the equipment elements;
Overload current protection;
Shutdown of the system or one of its sections when a leakage current exceeds 30 mA.

In the first two cases, the circuit breaker takes over the protection function, and in the last case, the RCD. You can combine two devices in one – difavtomat.

Material Calculation Example

To represent the level of costs for the installation of an anti-icing system, we will give an approximate calculation of materials.

Imagine that the hanging chute has a width of 12 cm and a semicircular shape. Its length is 20 meters, and along the edges of the gutter there is a pair of downspouts, having a height of 14 meters and a diameter of 10 cm.

In the process of calculations, it is taken into account that laying is carried out in three lines:

For each of the pipes, the length of the cable is selected. Here H cable is calculated as h * 3 (14 * 3) = 42 m. Suitable Thermocable SVK – 20 by 44 meters and a power of 0,9 kW.
For a gutter with three heating threads L cable = l * 3 = 20 * 3 = 60 m. Here we select the same cable as above with a power of 1,25 kW and a length of 62 m.

As a result, the installation of the system requires:

Thermocable SVK – 20 with a length of 44 m and a power of 0,9 kW (2 units);
Thermocable SVK – 20 with a length of 62 m and a power of 1,25 kW (1 units);
Thermoreg ETR 1447 type thermoregulator.

The total power of the anti-icing system (with a supply voltage of 220 V) is 2,9 kW.

The next step is the choice of protective automation. Here you will need a single-phase RCD for 30 mA of leakage and 25A of rated current, as well as a single-phase machine for 16 A.

Fastening is carried out in pipes and gutter using special clamps. The calculation is carried out taking into account 3-4 fasteners per meter of gutter or pipe.

The total length of the mentioned elements is multiplied by 4 and the total number of fasteners is obtained.

For our case, this is 14 m + 14 m + 20 m = 48 m. The final number is multiplied by 4 and we get 192 mounts.

You will also need a cable to fix the cable in the water drains. Here the formula is as follows – (Hcable + 1 m) * 2 = (14 + 1) * 2 = 30 m.

As a result, from additional equipment you will need:

Cable in a plastic sheath – 30 m;
Cable clamp – 2 units;
The number of clamps – (14 m + 14 m) * 4 = 112 units.

Features of cable fastening depending on the type of roof are listed below.

How much electricity is consumed?

One of the key factors when choosing an anti-icing system is the amount of electricity consumed. Please note that the power reserve of the equipment may not be enough to lay the equipment.

Below is the calculation, which is taken from the recommendations of the Moscow Committee for Architecture. It remains to make an adjustment to your tariff.

Operating costs are determined taking into account the cost of electrical energy consumed during the operation of all elements of the system.

The formula has the following form – C year = Pн*h*s.

Its terms:

Year – the price that the system costs during the year, p .;
Pn – rated power of the system, kW;
S is the price of 1 kW/hour of electrical energy, r.;
h is the number of hours the system operates during the year.

In order to calculate the approximate cost of maintaining the heating of the roof and gutters, it is important to determine the number of hours of its operation.

For this, it is taken into account that the system is active somewhere from November 15 to April 15, that is, 151 days or 3624 hours.

On average, 20% of this time the system is turned off automatically due to lack of precipitation or out of the operating temperature range.

It turns out that the total number of hours of work is lower. We multiply 3624 by a factor of 0,8 and get 2900 hours.

Below is an example of the annual cost of maintenance, subject to the connection of resistive cables with a total length of 100 meters and a power of 3000 watts.

Cgod = 3 kW*2900 h*1,05 r./kW*h=9,135 thousand. r.

In the case of using self-regulating cables, the consumption of electrical energy will be lower by an average of 12-15%.

Rules for the operation of the anti-icing system

To ensure trouble-free and long-term operation of the roof and gutter heating system, it is important to strictly follow the installation instructions and entrust the work to experienced workers. The latter must undergo the necessary training.

If you do the work yourself in the absence of the necessary knowledge, there is a high risk of not having the expected result.

The main rules of operation should include:

Installation of the anti-icing system should be carried out while still warm, before the onset of cold weather;
The roof and gutters must be cleaned of debris, and the system should be inspected twice a month. If a breakdown is detected, it can be fixed on its own or involve specialists;
Cleaning must be done with extreme care to avoid damage to the insulation. Please note that if the integrity of the cable is violated as a result of mechanical stress, the warranty is lost;
The settings are already made on site, taking into account climatic factors. When independently determining the boundaries of turning on / off the system, you should focus on the manufacturer’s recommendations.
