Do-it-yourself electric heat supply - how to choose, vitrata that is installed

Electric heat is used for the most rational solutions to improve the current scorching communications in the minds, if the central scorching cannot cope with the heating of the living volume.

The installation and connection of these structures are not considered to be particularly foldable - installation can be done without the involvement of third-party specialists.

Brief information and classification of heating systems

Schematic little povnyannya I will attach a resistive and self-regulating cable

Electrical sub-loga - all heating systems, which are composed of a cable heating element, a control unit and a temperature sensor. The system is connected to the streak line through the pull of the power cable through the cut.

The fundamental principle of heating the application for additional electrical supplies will be based on the method of convection exchange, if the currents that circulate for the charge are repeated, they are heated at a supporting base and evenly spread in space. Tobto, the process of heating the application is similar to that of the central scorch, it looks like a radiator and batteries.

According to the method of work, the heating elements are divided into two types:

1. Resistive cable - a one- or two-core cable, which is folded over one or two cores, which runs along the entire length of the heating element. The wire conductor is protected by a ball of insulating material with special metal braids, which play the role of grounding and screen shielding. The internal insulating balls and the core are covered with an oval insulator made of polymeric speech;
2. Self-regulating cable - the same double-wire cable, which is folded from the jet-conducting elements, burnt with a water-conducting matrix, which is self-regulating. The role of insulating speech is played by a heat-resistant elastomer with binding braids from a middling wire.

The main problem that is to blame in the course of operation of electric warm pipes based on resistive cables is the ability to overheat, the lack of unsatisfactory quality of the installation robots, the too low thermal conductivity of the cover, the high temperature and heating

Self-regulating cables allow this short period of time to be blocked in their design of a special napkin-conductor matrix, as they change and regulate tightness, reducing and increasing the strength of the stream, which should be in the system.

The main types of electrical heating structures

According to the form factor, cable ducts are subdivided into a heating cable and heating mats, de heating element fastenings to the armouring slositts.

There are no fundamental differences in robots and exploitation in these varieties. The main responsibility is the scope of zastosuvannya and the need for carrying out rozrachunk work.

The role of the regulatory block is played by a special thermostat, which is mounted near the premises of the room lighting, or in any convenient place. Depending on the type of heater, the regulator is allowed to adjust the heating system, adjust the control in the specified temperature ranges and carry out detailed programming about the hour of switching on, the temperature and the temperature of the heating.

The sensor for fixing the temperature of the heating is located at the insulated core with a special "head", which allows you to read the average temperature readings based on data taken from the space, which is heated, pinked between the resistive elements.

Crimium of the above-described constructions to the electric sub-logs is carried out by the plumbing and the shearing infra-red sub-log. Chip logs are based on the principle of infrared heating.

Dany pіdkhіd schodo "new" and not suitable for everyone, so within the framework of this material, I would like to focus on heating structures, which work on the basis of standard convection exchange.

Razrahunok sweatiness, electricity consumption and average vartist

When vikoristanny heating mat is carried out, the laying is not carried out

Razrahunok natuzhnosti pіdlogi z pіdіgrіvom vykonuєtsya z urakhuvannya a number of fаktorіv – korisna and zagalna ploshchenna primіshchennya, type priіmіschennya, presence of central scorching, type of podlogovy facing, vyavnіst vіkon and type vіkonnih systems.

By providing detailed information, you can more accurately develop the rozrahunok and select the specific tension, improving the specifics of the object and the minds of the exploitation of the heating design.

Zagalom, the development of tension is carried out only on the basis of the type of application and the presence or presence of the central scorching. So for a typical living room, bedroom and child, up to 20 m2 in area, the intensity of the heat supply for additional heating is not guilty of exceeding 120-140 W / m2, for the main buti we will not increase 150-170 W / m2.

For the kitchen, living room, pіdval or pіdsobki enough pressure 100-120 W/m2 for additional heating and 140-160 W/m2 for the main one. In applications with advanced moisture, it is necessary to use high pressure systems with an intensity of at least 120-130 W / m2 for additional heating and 150-170 W / m2 for the main burning.

Vitrata elektroenergії without intermediary to lie down due to the severe tension and the frivolity of the robotic system. For example, maybe a typical room with a laying area of ​​10 m2. The power consumption per square meter does not exceed 130 watts.

As a result, it turns out that it will be more than 1.3 kWh/year, which is 4-4.5 rubles/year for the average tariff. In the middle, the vitrata be like warm underlays, with victoria on an area no more than 60-80 m2, it will be approximately equal or wind the lower one in equal parts with some kind of heating device of similar tightness.

The only difference is that during the operation of warm weather, there is no actual decrease in moisture content, which draws discomfort and possible health problems.

Before that, how to choose the best option, we recommend that you familiarize yourself with the star table, which shows the average quality and intensity of the most popular brands represented in our country. On top of that, we waived the average windows for these projects, taking into account the fact that the area covered is approximately 15 m2.

Creation of a plan for the distribution of heating elements

Overhead scheme that shows the possibility of laying a double-core heating section near the bathroom

Before the preparations for the heating system and the preparation of the supporting system, it is recommended to draw up a plan-scheme. For whom it is possible to victorize a great or a millimeter papier.

In the process of transferring to scale, the laying of a resistive cable or heating mats is covered, that the laying of the underlayment with the support of the important furniture, the objects and accessories will not be removed.

At the places of passage of pipes of the central scorch and risers, there is a safe zone, which makes it difficult to lay additional heating systems. Temperature gap between walls - 5 cm, between scorch pipes - 10 cm.

Overhead scheme that illustrates the possibility of laying a heating mat near the bathroom

If these rules are ignored, there will be a constant overheating of the heating circuit, surrounded by furniture, which in the last bag will bring up to the first overheating, the way out of the fret will be pokodzhennya objects.

Dodatkovo sled to ensure that for a particular application, the transfer of the heating circuit, connections to a specific thermostat is to blame. For use with increased moisture (bath room, laundry room, sanitary facilities), the thermostat should be placed outside the room.

As a result, on the scheme, the main area of ​​​​application, the place of refurbishment of large objects and furniture, the refurbishment of the temperature controller and the laying of the heating cable will be indicated.

Preparation of the basic and necessary tools before work

Usunennya small poshkodzhen can vikonati for additional special putty

The technology works from the installation and installation is punishable by a complex of preparatory visits, which includes the dismantling of the old workmanship and the alignment of the ball, the removal of cracks and cracks on the surface base, the priming of the surface marking.

Dismantling of the old trim is used only for foundations with wooden underlays or cladding. For the obviousness of the work of looking at the tiles, dismantling work is not required. After the adoption of the old lining, a thorough cleaning of the premises is carried out in the saw and the wakefulness.

The main stages of pouring a cement screed for very loose foundations

• Dodatkove dzherelo heat - zdіysnyuє zatyrannya and usunennya possible poshkodzhen on surfacing pіdlogi. For thermal insulation of the base, it is possible to vicorate a standard thermal insulation material based on spun polyethylene;
• The main source of heat is the construction of complex robots from the foundations. After hanging the sums of rubbing on the surface of the ceiling, a polyethylene slab is laid with an allowance for the wall area. The expanding seam is glued and the extruded polystyrene foam is laid with a thickness of 50 mm. An armored mesh is laid on the expanded polystyrene, until a resistive cable is fastened;
• Cold application without scorching - a new complex of repair and waterproofing robots is being built. The damper line is glued, the heat-insulating material of the curtain 100-120 mm is laid and the reinforcing mesh is laid.

In warm applications with a base, which do not have strong differences in height, it is necessary to carry out a simple cleaning of the application of saw and abrasive particles before it, like laying the electric heat to the base. Then, one or two balls of a deeply penetrating primer are applied to the surface of the overlap, and the mark is made according to the scheme, as the bula was folded earlier.

As a tool, it is necessary to prepare an electric drill with a nozzle for opening an opening, a grinder with a disk for concrete, a screwdriver, a flat slotted screw, a hammer and a chisel. Dodatkovoy can prepare a nozzle-mixer for the preparation of a cement screed and a container for mixing.

Instructions for installation, installation and connection

Mechanical and sensory regulatory block for heat supply

For installation of installation robots, it is necessary to supply a standard set of cable connections or a set of heating mats, a temperature controller. For cable heating systems, you need thermal insulation, metallization adhesive tape, mounting lines, fastening or self-mounting lines for mounting lines.

The temperature regulator can control the hot exhaustion of the system. In another way, the control and additional functions of the regulator are selected according to special needs and advantages.

Before buying a set of electrical connections and a regulator, it is recommended that you familiarize yourself with the possibility of laying the power cable of the required span before the installation site. For systems with a high intensity of up to 4 kW at 19A strumi, a copper conductor 2 × 1.5 mm can be used. For tightness, 5.8-6 kW and a struma 27A should be filled with an aluminum rod with a 2.4 mm perforation.

After rechecking the possibility of extending the conductor and connecting it, the preparation of the site for the installation of the thermostat is carried out. For whom, in the selected area, with the arrangement of the crossed scheme, the mark for the opening of that communication channel is fixed.

Stages of marking and extension to the channel for communication and regulatory block

The height of the roztashuvannya is included in the windrow 50-150 div in the surface underlays. The width and depth of the channel for communications is 20 mm.

The drilling of the opening is carried out behind the help of an electric drill with a special nozzle, drank the contour of the channel behind the help of a grinder with a disc on concrete. To remove concrete from the contour of the channel, a hammer and a chisel are used. After the selection of surpluses of concrete, the introduction of a power dart from the central barrier is carried out.

Further installation of a cable sub-log with your own hands is consummated in a kіlka stages:

Laying the heating cable under the screed is the most optimal solution, since the screed ensures even distribution of heat over the surface of the entire base, without dampening the original cold. After 25-28 days, it is possible to prepare the flooring of any kind of facing coating, with the improvement of the coefficient of thermal conductivity and the tension of the electrical underlay.

Before purchasing the necessary materials and installation, we recommend that you familiarize yourself with the installation video with your own hands. In addition to the installation technology described above, we brought another video material, which shows the installation of electrical mats.
