Heating roof and its functions

Now this innovation is only in widespread use. Many people neglect the roofs of the roofs, because they are afraid of excess waste of electricity and cash on the creation of the system itself. However, it is worth thinking about that such an approach can lead to an accelerated failure of roofing pie. This will result in unscheduled repair, and, consequently, the extra financial costs. Let's figure out how the heated roof protects the roof.

So, the use of this system allows you to get rid of systematic land, which causes significant harm to the structure, disrupting its waterproofing. By the way, you should not hope that the problem will solve the timely cleaning. It will not cope with the whole volume of moisture accumulating on the roof and drainage. In addition, when heating the roof, you get rid of falling icicles and snow, thereby raising safety.

There are other ways to deal with icing. For example, the arrangement of a special ventilation system attic or roof treatment with anti-icing emulsions. However, all these methods are imperfect, require constant financial costs and take you a large amount of time, and also reduce the temperature inside the building. Therefore, the best option is the right roof heating.

What is a roof heating system

It is called differently: the synthetia system, heating system or antite. It consists of a device from a large number of sensors, wires, executive and measuring instruments, as well as heating elements. Such a complex prevents the formation of icing on the surface of the roof and does not give to accumulate over the snow.

It is not necessary to heat the entire surface of the roof, so for the installation of heaters, certain places are selected, which are the most susceptible to the accumulation of ice and snow, as well as places that can skip moisture inside the roofing pie. So the system must necessarily cover the edges of the rods and the surface of the Endament, as well as cover the entire length of the drainage.

Important! The roof heating system must necessarily be lower than snow-holders. First, it will not allow not to spend too much electricity to warm the roofs that do not require this. Secondly, the melting of the snow cap on the roof increases the thermal conductivity of the roofing pie, which attracts the accelerated heat loss.

It is also convenient that the cables can be mounted and after the end of construction at any free time, because the system is most often located on the surface of the roofing material.

If the heating system of the roof of your home is performed correctly and competently, then you can forget about falling from the roof of the snow. Even such a device facilitates the load on the rafter system, which contributes to greater durability of roofing pie. Additionally, you will get a good protection of the drain. After all, there are frequent cases when it cracks from the overlaneous accumulated water.

By the way, the anti-icing system eliminates the owners of the house from the regular manual cleaning of the roofing material.

How the roof heating system is arranged

Let's figure out what basic elements are included in the system and how they should be located.

Approximate Scheme of Gasket Heating System on Roof Source Dom-electro.ru.

The whole complex of heating equipment usually consists of three main components.

The heating unit includes a network of single or double heating wires. Also at this point it is worth indicating that a special film can be used as a heating element. It is important that heating elements meet certain requirements. They must be adapted to the sharp drops of temperature, as well as to the voltage jumps. Another system should be resistant to excess moisture. If you are planning to walk on the roof, then resistance to mechanical damage is a mandatory requirements for the heating unit.

The information and distribution unit is intended to control the transmission of electricity from the network to heaters. This part of the system provides information in the form of sensor readings and nourishes all components of the anti-icing complex. Install all sensors and elements of this block are better in places where moisture does not fall. For example, in the attic or under the sink of the roof.

The control unit includes thermostators, weather sensors, as well as instruments that allow you to change the temperature of the roof and supply of electricity manually. A variant with a self-regulating control system is possible. It disappears the need to constantly regulate the operation of the heating complex, and the necessary changes are entered automatically. In this case, the mini-computer makes decisions based on the testimony of weather sensors.

How to choose the heating system

Such systems differ primarily by the type of heating element. Options are possible using cable or film heaters. The second method has a lot in common with the "Warm Paul" system. An important difference is that the film should be inside the roofing pie, because it is not designed for serious loads and is weakly adapted to mechanical damage. But the cable is the opposite, it may be on the surface of the roofing material. But the wire can fit inward. This is usually used in the device of the heating system of flat roofs, and during the construction of high-rise buildings. For heating drainage grooves and pipes used exclusively cable.

The cable is used for the outer heating of the roof Source Domsireni.ru

Characteristics of different types of heating elements:

This is a matrix with insulation of the polymer and two veins of the wires inside. Also here includes a metal strip and an additional layer of insulating material. If the outside becomes warmer, then the number of conductive pathways inside the matrix decreases and due to the temperature of the heater decreases. The advantages of this type of heater a lot. First, the installation of the cable is performed quickly and does not require greater experience. Secondly, the matrix itself is resistant to rehearseers and point heating, thanks to the temperature self-regulation system. Thirdly, it is possible to use such a cable in a complex with absolutely any roofing materials. An important advantage is that the system chooses the optimal temperature and thereby prevents the consumption of excess electricity. It is possible to install such heaters without the use of weather sensors, as well as with the help of self-regulating cable you can dump the drains.

Self-regulating wire is most easily mounted on the roof Source raychemfutokabel.hu.

Resistive wire

Heating is due to the resistance of the conductor. Such a cable may be dwelling and single-core. Isolation is made from a layer of polymer, and a nichrome core is used on better models. When installing such a cable, you need to pay attention to the fact that the beginning, and the end of each wire must necessarily converge at one point. There is one pretty serious minus of such a heating system: in the case of point damage, the entire anti-icing complex fails. Installation is inconvenient, because the resistive cable cannot be cut. This method is suitable for heating the large areas of the roof.

The resistive system is more complicated, it is better to entrust the experienced master Source Teploobogrev.ru.

Warm heater

It is a flexible film, with veins of carbon conductor. Heats such material with the entire surface, since conductive bands are located often and throughout the heater area. Very convenient to transport and store, because such a film is sold with small rolls. This material is attached only under the roofing coating, so it can only be used in the case of the roof reconstruction or in the construction process. Installation of such a heater should be entrusted to specialists. When local damage occurs, the heating system does not fail, but loses efficiency. In the process of repair, there is always the opportunity to replace the damaged portion of the film heater. I would like to note that the film is very safe, it is not self-ignited. Uniform surface heating gives good electricity savings.

When choosing materials, it is worth paying attention to their cost. More expensive to use a film heater. A self-regulating cable is a bit cheaper, and the most fiscal option is a resistive wire. But I would like to note that heating the roof using self-regulating cable is more economical and in the future will give good benefit. Also note that the installation of an anti-icing system on the surface of the roof is possible only in the presence of snow holders. Otherwise, the entire network will be simply torn with abundant snowfall. Various improvements and options make the entire complex more expensive, but the choice remains always for you. Remember that ordering the heating system for the roof should be based on the features of your roof.

The heating system is chosen on the basis of the type and features of the roof Source MS.DecorexPro.com.

Installation of the roof heating system

First you need to figure out what kind of roof zone requires heating. As already mentioned, these are rtends, sills and places of accumulation of a large number of snow and land, as well as drainage. It is worth paying attention to that the benefits of partial heating of needing zones are significantly lower than that of the roof heating on all problem areas. After you have decided on the area that you should heat, you need to calculate the required amount of materials and purchase them.

So, after all materials are selected and purchased, you can start the installation. Below you will find information that the entire system should be installed correctly.

Experienced hands will not allow mistakes when installing the roof cable heating system Source Promalp-moskva.ru.

First of all, it is worth completely cleaning the entire surface of the roof, as well as drainage from garbage or leaves. Next is installed in the required places the fastener tape. The next step is the installation of the junction box. It is worth bringing and consolidating the "cold" end of the cable, pre-extended in the corrugated tube. After performing this procedure, decompose the cable inside the drainage gutters, fixing it with the help of the fastener tape. Now you need to fix the wire inside the drain pipe. For this, the cable is attached to the chain, for example, plastic screeds, and the whole system is taught in the pipe. After that, it is worth securing the upper segment. The lower edge can be fixed using metal ties. Next, it is necessary to decompose the loops over the surface of the roof and consolidate them using the tape for this mustache. If the roofs of the roof are too cool, then it will be better to add plastic ties. Now you can install weather sensors. They should be positioned on the north side of the structure next to the junction box. The next step is to check the entire wire system. The quality of the system can be determined by measuring resistance to the chain and comparing the obtained readings with the data specified in the product passport. It remains only to fix the control panel indoors. After the installation is completed, you need to measure the temperature of the system to compare it with the data entered by you.

Video Description

With the order of installation of heating roof, gutters and drains can be found, looking at the video:

If the verification showed the correct result, it means that the installation of the anti-icing system is made correctly. In this case, you get a good reliable heating of the roof and drainage. Such a system will increase the service life of the roof, as well as eliminate the inconvenience associated with the fall of icicles and snow from the soles.

Conclusion

The competent selection and high-quality installation of the roof of the roof of the roof will avoid the problem of blocking the drain channels and the destruction of the entire drainage system when snowing from the roof. But the design and installation of roof heating is better to entrust professionals, because otherwise you can get a system that consumes too much electricity or does not cope with your duties.

The cable heating system of the roof and drainage is an anti-icing system, which is based on the use of electric heating cables for stating snow and ice on the roof and in the building of the building in the threatened periods - at a time when the daily temperature drops and the formation of the land is probably the most likely.

In turn, it is the land that the roofs are caused by the roofs in the autumn-spring period, as well as the cause of the deformation of the gutters and drainage due to ice and snow accumulated in them.

Since the cable system of the roof of the roof does not allow education and, accordingly, the drops of icicles on the adjacent territory, it is referred to as security systems.

It is quite natural that in 2004 a document of Moskomarchitectures "Recommendations on the use of anti-icing devices on roofing with outer and internal waterproofs for under construction and reconstructed residential and public buildings" which directly recommends installing such systems on all new buildings.

Currently, several thousand buildings are equipped with cable heating systems of the roof in Moscow and St. Petersburg. Created considerable design, installation and operation experience.

A properly designed and competently mounted cable heating system of the roof on high-quality components does not allow accumulation of ice and provides thawed water allotes throughout the path. As a result, the roof itself serves longer, the gutters do not bend, the drains are not deformed and the drops of sucking near the building are not threatened with people and cars.

Heating roof in photos

• Heating with a warm and cold roof

  • In the case of a cold roof (having minimal heat loss), it is enough to carry out the audit of the drainage system and install the heating cables in the gutters and drainage.
  • In the case of warm roof, it is very likely that it will be necessary to install both other sections: endowers, drippers (cornices), attic windows, adjoins and overhangs.
  • If the roof is completely intimidated, the installation of the CSR can be economically not justified and the reconstruction of the roof.

  Composition of the system

  The most successful thing seems to us the following classification:

  1. Subsystem of heating elements

  In addition to heating cables for operation on the roof, elevated requirements are imposed:

  • ravenly power: at least 20 W / m and no more than 60 W / m at 0 ° C;
  • resistance of shells to UV radiation;
  • local overheating resistance;
  • reliable work in wet conditions;
  • presence of shielding braid;
  • certification of compliance with TP TS 004/2011 "On the security of low-voltage equipment";
  • certificate of conformity Tr Ts 012/2011 "On the safety of equipment for work in explosive environments" * (if the building is in an explosive zone, such as a gas station).

  In the composition of the heating systems of the roof and drainage, resistive cables and self-regulating cables are used.

  The advantages of resistive cables include low cost and stability of power characteristics. The disadvantages are the inability to change the lengths of the sections and the probability of overheating. On soft (weaving) roofing, resistive cables cannot be used.

  Resistive Cables for Roofing

Heating roof and drainage has become an integral part of the design of modern buildings. It is necessary to improve comfort and the level of security by opposition to icing the functional elements of buildings. Visual confirmation of the validity of the use of such systems you can observe in the spring when there is a massive gathering of snow and ice from the roofs.

If the roof heating system is not installed, it bears the potential threat to the life of people. They are at risk to get a serious injury thickened with a height of ice weighing. In addition, it becomes necessary to regularly repair the drainage system, which is destroyed both under the excess weight of the nondes, and during the snow from the roof. All this can be avoided due to a fairly simple solution to the solutions.

The equipped heating of the roof and drainage is guaranteed to prevent both an accident and regular damage to the drainage system. It effectively prevents the accumulation of snow masses and the formation of land. Once upon a time he adopted and embodying him in life, you will stop worrying about the security of passers-by and vehicles, as well as the preservation of the integrity and functionality of the elements of the drain.

Anti-location roofing

Our enterprise provides 100% protection of roofs and elements of drainage systems from a tree and snow drifts. The roof of the roofing system consists of:

1. Heating cable sections. This is the main element. The laying of the cable is made with the formation of threads in an amount of from 1 to 4. Installation of heating of the roof and drainage is performed on such elements: gutter, drainage, funds, drippers, etc. Apply one of two types of cable - self-regulating (preferable) and resistive.
2. Cabinet control. No less important part of the system than a roof heating cable. It is intended to place electronic control components that are needed to automatically control performance. The kit includes equipment to protect against closure, overload, current leakage. The control category of control cabinets is usually not lower than IP67.
3. Fasteners and installation elements.
4. Electrical distribution system. This category of equipment includes cables and junction boxes.

Attention! The heating system of the roof and drainage should be used before precipitation. If the moment is missed and a significant amount of snow accumulated on the roof, then the full cleaning of the surface becomes impossible.

Saving

Professional installation is one of the conditions for reducing costs. If the anti-change system of the roof and drainage was established with violations of requirements, technologies, or using low-quality materials, the cost of its content increases significantly. At the same time, after the competent installation, the need for seasonal maintenance almost disappears. Also reduced the risk of equipment failure. Our company not only guarantees high-quality installation, but also the repair of systems established by other performers.

Take care in advance

In the climatic conditions of our country, on the roof is always formed. Heating of the roof and drainage is the only way to impede these natural processes. Do not tighten with the decision before the onset of cold weather. Installation of the system, including for a soft and flat roof, to cooling is correct. In the spring and summer is cheaper.

The roof without icicles is:

• durable aesthetically attractive appearance of the building;
• minimum roof cleaning costs;
• safety for people and property;
• long term of operation of the drain and other structures.

From where icicles appear

If the installation of heating of the roof and drainage is not fulfilled, the formation of icicles can be predicted with 100% probability, regardless of the type of roof, as well as the category of thermal insulation - cold or warm.

Cold roof Does not give heat into an external environment, but the snow melts under the influence of the Sun, and the water runs into the frozen drain.

Result: Water freezes in the catchment system - icicles are growing.

Warm roof Due to the lack of sufficient thermal insulation, it gives heat into an external environment. Snow melts throughout the winter period.

Result: Water constantly runs into the drainage without heating - icicles are growing.

Solution to the problem

The best way out of the situation is a self-regulating cable for heating the roof and elements of the drain system, which is characterized by the highest energy efficiency.

Mounting work

Installation of the system is performed in problem areas using galvanized steel fasteners. The "Heated Montage" company guarantees that the price of heating the roof and drainage will be as acceptable, quality and reliability - high.

Example from our work:

Used main equipment

Heating cable:

The main element of the electric heating of the drain is recommended to use a self-regulating production cable. CST

The effect of self-regulation of the heating cable self-regulating is based on the use of a special semiconductor matrix in it, which changes its conducting properties, depending on the ambient temperature, the matrix resistance increases with increasing temperature, which means that the flowing current decreases, which in turn leads to a decrease in the heat output. When the temperature decreases the reverse process. At the same time, each section of the cable of heating self-regulating changes its properties from a specific temperature on a certain area, regardless of other sections. Consequently, the cable heating self-regulating cannot overcome even when overheating.

What happens at the stage of survey and develop a technical assignment

• development of a roof heating plan
• building a building plan, indicating the intended location of the control panel (SHO) cable heating system, as well as the location of the main distribution shield (rchit)
• definition of structural features
• calculation of the power of the system and the calculation of the estimated operational costs

How do we create roof heating systems

1. Private sector

We carry out installation on a variety of roof forms.

We work with with various power tracks, so the cost of projects will vary greatly.

The management system in residential buildings is usually installed only on the thermostat if the meteorological station is used, this significantly saves electricity costs;

We work with minor volumes.

Installation performs electrician. Works above 1.8 m performs a climber.

We introduce the project in the conditions of limitations on the power allocated under heat heating.

2. Buildings, business centers

As a rule, commercial objects characterize a large limit of power generated under heating.

Detailed matching of the installation of the system (including the preparation of project and executive documentation).

Experience with large volumes.

We work with branched power tracks (power supply).

Non-standard architectural solutions of such structures lead to the need to apply special equipment and equipment during installation (autotower, climbing equipment, tour, etc.).

3. Industrial objects

We have experience with a detailed coordination of the installation of the system (including the preparation of project and executive documentation).

Experience in setting systems for aggressive media and non-standard operating conditions.

The use of special equipment is often required, usually not enough climbers. Sometimes, at installation, special equipment is attracted (autotower, climbing equipment, tour, etc.)

Full cycle of cooperation

• departure to the object, examination, development of technical specifications
• preparation of a commercial offer
• conclusion of the Treaty
• preparation of project documentation, if necessary
• delivery of heating cable, feed cable, automation, attachments and related materials;
• installation of heating cable on the roof, in chutes, drain pipes, drippers and endowes
• connecting the control system, roofing automation (remote control, meteorological station)
• stacking, commissioning system
• signing an act of reception

What problems will solve the cable?

The main task that the roof / roof cable heating decides is to prevent the formation of forehead and ensuring the continuous removal of melt water from the roof / roof at any (even the most unfavorable) natural conditions.

1. Problem: Bad water removal with the so-called "warm roof / roof", education and further accumulation of ice in horizontal grooves and trays, clogging ice vertical drainage pipes. It leads to breakdown even the highest quality drainage system.

Decision: Heating of the drainage system of horizontal gutters and trays, as well as vertical drainage pipes. Increases the service life of the drainage system, it provides a constant removal of water with a "warm roof" or roof / roof on which electrical heating elements are installed.

2. Problem: The formation of a land and large snow masses on the edge of the "cold" eaves and sols. As a rule, this occurs in areas behind snow supporting structures or standing gutters of folded metal roofs. The possibility of a breakdown from the edges of the roof of large snow-ice masses is a threat to the life of people and possible damage.

Decision: Heated roof / roof cornices. Proper laying of the heating cable at problem areas of the eaves helps prevent the accumulation of snow and ice masses and take a timely tolery water without its further freezing.

3. Problem: The accumulation of snow masses in the complex areas of the roof / roof - in endowes, around various roofing structures, near the funnel of inner drains, which leads to damage to the roofing coating.

Decision: Heated roof / roof sections. This part of the heating system minimizes the likelihood of leaks. It also reduces the mechanical load on the roof / roof elements and increases its service life.

It should be remembered that the control elements (thermostators, thermostats or meteorological stations) are needed in the roof / roof heating system, even if a self-regulating cable is used! The late inclusion of the system can lead to aggravation of problems associated with the formation of ice.

Examples of some worked technical solutions for the installation of cable heating of the roof / roof and drainage

Heating of gutters and drains

Double laying of the heating element in the groove on the roof of the hospital. In general, there are 8 such waste grooves, the equipment of which required about 300 M self-regulated cable with a power of 18 V / m.

The heating element is made in the form of a double laying of self-regulating heating cable with an exit to the bituminous roof.

Heating roof / roof and drainage

As a fastener, self-adhesive aluminum tape was used. Temperature and precipitation sensors ensures fully automated economical system functioning.

Heating roof / roof and drainage

The heating for the roof panels was found in May 2013 on the metal sheets of the office building. Through the use of zinc mounts, heating elements are reliably protected from wind gusts and firmly fixed in their places. About 900 m of the heating line was laid out in the form of meander (in the form of loop-shaped bends) at a distance of 100 mm from each other. From the courtyard of the chute and pipes were also equipped with heating systems. Both systems have been equipped with digital temperature and precipitation sensors with double-zone adjustment (2 sensors for drainage).

Electric heating roof / roof and drainage

For the safety reasons, the roof and rapid slope of the total width of about three meters to the flame retardant partition was equipped with a heating system. This special situation arose as a result of expanding the existing building (side extension), the modernization of the old roof design was impossible. For the most economical use of the system, temperature and precipitation sensors were installed.

After the unusually snowy winter 2010/2011. There were problems with this building in Moscow - snow and ice fell from the cornices of the building. To solve the problem, we installed the heating elements on the edge of the eaves. A system of protection against pigeons installed earlier was used as the main fastener element. For the most economical application of the heating cable system with a total length of 60 m, we installed a digital temperature sensor and precipitation.

The heating system of the movable roof / roof and drain (400 m2) with a plastic coating of a 400-volt heating cable (excess pressure from the building constantly led to the roof coating elements). The distance between heating cables is 100 mm, as a result of which the output power is 300 W / m2. This system allows you to safely and reliably pull the snow and ice drifts with a height of up to 2 m (without additional heating). Due to high power, the system is able to prevent snow accumulation and ice on the roof even in the strongest frosts. The fasteners are fixed with a special glue, which provides lightning protection of the heating system.
