How to cut the warm floor Tepllyux. Short the cable

Is it possible to shorten a heating cable or a warm floor mat

Structurally, the mats of the warm floor are sold in the format of the finished, for installation, kit.

As a rule, a warming floor cable is a two.core. Both veins are hermetically tight to connect with each other.

Warm floor, has maximum power, due to the fact that the warming cable has a certain length, as well as reliable hermetic compounds.

If you were mistaken and purchased a mat longer than you need, you can not cut the wire.

It is permissible, reducing the wire installation step by cutting part of the synthetic grid.

Before this operation, consult a specialist.

The best option is an exchange for 14 daily, for a smaller area, in a store where they made a purchase, subject to the preservation of a commodity species.

Resistive heating cable

The resistive type electric for a warm floor has one or two cores that are placed in the insulating shell, and coupls are installed from both ends, with which the electrical network is connected to the electric network. If a single.core wire is used for screed, then it is necessary to provide a closed circuit. This means that the cable should be placed on the floor so that both ends enter the mounting box.

If a two.core wire is used, then the presence of the second conductor provides a closed circuit of the current, so only one end is placed in a box, and a plug is mounted on the second.

A two.core cable has a more complex structure:

Two.core heating cable for a warm floor

  • Both veins are placed in insulating material, for example, silicone rubber;
  • Two wires are combined with fiberglass;
  • For grounding, a conductor made of tinned copper is used;
  • Aluminum foil protects from local overheating of the vein;
  • The entire structure is placed in the outer shell made of polyvinyl chloride.

Self.regulating cable

A shielding or self.regulating cable for a warm floor is a matrix, inside which two guides are placed, and between them. a layer of polymer, which releases the necessary thermal energy. A feature of this cable is that it regulates heating due to the resistance of the polymer. With an increase in temperature, the resistance increases, which leads to a decrease in current strength and, as a result, the amount of heat released decreases.

Thanks to this structure, the self.regulating cable is also quite economical, so over time it will justify the means invested in its purchase.

Despite the ability to control overheating, such a cable is also not recommended to be laid under furniture, since this will increase the consumption of electricity, but will not provide the necessary effect. it is pointless to heat the cabinet.

Heating mats

Methods of cut and bending of a heating mat to simplify the installation of a warm floor using a heating cable, special mats were developed. They consist of a grid base on which the heating elements are fixed.

The main advantage of this design is that you can not make a concrete screed, but it is allowed to immediately lay the finish layer on top (most often used tiles).

Matu installation is very convenient, because it is easy to change direction, you can lay it in any order, bypassing the location of the furniture. Most often, a resistive two.core cable is placed in mats.

65.00 UAH.Cutting for shortening the heating cable

Replace the warm floor with another size

Heating cables are designed for a certain area, even at the manufacturer factory. They are not sold on a cut

But in some cases it happens that the coolant has already been acquired, and the area of ​​the room has decreased by adding furniture (or other causes), a problem arises, since it is impossible to set a cable to closed places, which will lead to air locking, and in the future it can lead to the exit Cable is out of order. In ideal occasion, it would be good to make a replacement of the section with a smaller area.

What else can be done with a heating floor (is it possible)

(Information also applies to the heating mat of a warm floor)

You can simply raise furniture by 1.5-3 cm by mounting mini-legs (which are purchased separately, in the closet you can drill 1-3 holes inserting plastic covers, all this is necessary for air circulation. This is the first exit from the situation.

You can also reduce the step of laying the wire, by reducing the distance between the turns within the limits indicated by the manufacturer (usually up to 7 cm). After decreasing the width of the styling, you need to fix the places on paper or photographed in order to know the location of the cable under the screed in the future, this will simplify the determination of the breakdown if this happens. It is still possible to lay part of the remaining wire in a combined room or even on the walls, or lay the rest of the cable around the perimeter of the room near the skirting board, but so that it would not overheat (t.e cover with tile glue or concrete).

The choice of electric and water warm floor (read)

Well, nevertheless, is it possible to trim the heating cable?

The cable can be reduced by 10% of its length, no more (in extreme cases). In order to shorten it with special tools and materials, such as heat.shrinkable couplings, squeezing sleeves, construction hair dryer. Cable coupling places are considered the most unreliable in the system. Therefore, this work is not worth doing on your own. Since if the wires will have to be repaired again, with improper coupling or sealing the wire, and for this it is necessary to remove the finish coating. This robot is best provided to a specially trained specialist.

Remember the heating cables and mats are very reliable, since they are made on the base of the metal. nichrome, but this metal is very unstable to the excesses. Be careful!

Cable warm floor: characteristics and features

At the present time, there are many special systems on the building materials market that provide heat in the premises. All devices have their own technical characteristics, features, they differ in design. A variety of warm floors are available to consumers: liquid, film. Today the cable warm floor has gained great popularity. There is nothing surprising: after all, such a system is distinguished by a large number of advantages.

Keep your feet warm: everything you need to know before buying a warm floor in the form of heating mats

The article was prepared with the participation of Leroy Merlen specialists

Heating mats for a warm floor gradually become the most popular heating method and apartment, and a country house. Sometimes they are combined with heating radiators, sometimes the heat loss of the room allows us to limit themselves to “mats” alone. The heating mat is relatively inexpensive, mounted in two accounts, serves for a long time and, most importantly, evenly warms the floor, so its popularity among consumers over the years is only growing. In what rooms are heating mats, how to mount them correctly, how to save electricity and what to pay attention to when buying, explains Natalia Terekhova, head of the “Electric product” of Leroy Merlen.

The main difference between mats and ordinary electric warm floors is that the cable is already laid on the grid, and thanks to this, the installation time of the warm floor is significantly reduced, the uniformity of laying is ensured and, accordingly, heating the surface.

The heating mat consists of a thin heating section fixed based on plastic, silicone or other mesh. The heating section, in turn, includes a heating cable, power wires and couplings that provide hermetic connection of the cable and power wires.

Heating mats and sections are one.core and two.core. One.core have two installation wires, so during the installation process the second end must be returned to the starting site of the installation. Two.core warm floors have one wire connecting to the nutrition, a sealed end clutch is installed at the other end, so there is no need to return anything, styling is simplified due to this. This is a serious choice: one.core cables are cheaper, but two.core are easier to lay. The difference, in essence, in the method of connection.

The service life and safety of the warm floor directly depend on the quality of the cable in the heating section and the quality of the coupling joints. Modern cables are made of specially developed materials, so they are really durable. the warm floors of some manufacturers serve 25 years.

For additional protection against electric shock, the cable has a screen of alumo.olavsan tape.

The power of the heating mat is determined by the pitch of the cable laying. the distance between fragments of the heating section fixed on the grid. In most heating mats, the laying step is such that the power is enough for both the main and comfortable heating of the room.

How to understand whether a heating mat is suitable for your house or not? It all depends on the shape of the room. If this is a simple square or rectangular room, then mats for you.

It is in such cases that a matter of minutes will go on the installation of mats. The mat rolled out, fixed on the surface in several places with a solution or glue, and you can fill.

In complex rooms, rooms with bay windows, etc.D. it is better to use not mats, but only a heating section.

In addition, experts recommend setting a heating mat where it is impossible to raise the floor level. The fact is that, unlike heating sections for which a screed is 3-5 centimeters thick, mats are installed in a thin layer of tile glue.

How to choose mats: area and power

Armed with these theoretical knowledge, you can proceed to the practical part: how to buy a warm floor and never regret it? What to pay attention to first?

When choosing a warm floor in the form of a heating mat, first of all, you need to pay attention to the heating area, since you cannot shorten the heating cable. Mat with one power supply is more convenient for connecting than with two.

The power of the mat is an equally important parameter than the heating area, and here it is appropriate to say about another advantage of the mats over the usual electric warm floor: the power does not need to be calculated, since it is laid down with a step of laying and cable linear power. The only thing: we must take into account where we are going to install mats, since different power is recommended for different rooms.

warm, floor, tepllyux, short, cable

So, the power of the mat per 1 m2:

  • 120 W/m2. for comfortable heating;
  • 140-150 W/m2-for cold rooms and premises on the first floors;
  • at least 150 W/m2. for the main heating.

How to repair a damaged electric floor heating system

These conditions in power per square meter are characteristic, as a rule, for all manufacturers of a warm floor.

Thermostats: simple or programmable?

Thermoregulators are used to manage the heating systems “Warm floor”. These are devices that control the surface temperature. That is, at the signal of the sensor installed in the heated surface, the thermostat turns on or turns off the heating mat.

Simpler.regulators simply maintain the set temperature. Programmable allow you to include heating only at that time (days and hours) when it is really necessary when the tenants of the house. It is programmable thermal controllers, controlling comfort in the house, that allow us to significantly save electricity.

According to experts, the use of programmable thermostat gives up to 70% of electricity savings. Well, in addition, you can save on electricity with a simple decrease in the maintenance of the main floor temperature.

In all models of a warm floor, thermal controllers are installed in the wall, such as a socket or switch. Therefore, you will have to make a choice not only between the usual and programmable thermostats, but also to pay attention to the design and color so that the thermostat harmoniously fit into the interior.

Is it possible to cut a warm floor in mats

When installing an electric warm floor, there are situations when the extra segment of the cable remains. The most common reason is errors in calculations. For example, when determining the desired meter of the cable, the area of ​​the room was confused with the linear length. How to be in such a situation and where to put the rest, we will tell in this article.

Exchange for the cable of the desired length

If the error of the length of the heating element was understood before the start of installation work, the warm floor can be exchanged in the store. If the situation has become clear after the start of installation, such a cable will not be taken back. But the way out can also be found. For example, if the error turned out due to incorrect calculations of the foreman, he can buy a new cable. The heater that did not fit is to pick up for objects where it will suit more.

Change the step of laying

You can get out of the situation by changing the distance between the turns of the cable. You can reduce the styling step only within the limits specified by the manufacturer. Changes should be made in the documentation on the warm floor, and the location of the cable is photographed or drawn by manually.

Put under furniture

Usually when drawing up the location of the heating element of the warm floor, the placement under the furniture excludes. Firstly, it is pointless. Secondly, the pressure on the heating cable creates a load, causes overheating of the heater. Laying a warm floor for furniture is justified only if sofas, cabinets and chests of drawers have legs and will not put pressure on the floor with all weights. In the bathrooms, an extra segment of the cable can be mounted under the bath. Also, the problem will help to solve the heater laying in adjacent rooms or on the walls.

Cut off or not?

In extreme cases, an option is allowed with a segment of a piece of cable, not more than 10 % of the length. It is extremely not recommended to do this on your own. Work should only be performed by a specialist. For trimming you will need special tools, knowledge and experience in this area. If in the process of shortening the heater to make an error, it will simply completely burn out.

Distinctive features

Warm cable floor is mainly heating wires.

In design, such systems are divided into several types:

  • One.core. In such systems, the heating element and the conductor is one core. Such wires are characterized by increased radiation, so you should not use them in rooms where people often come.
  • Two.core. They consist of closing and heating wires. The radiation is minimal, so such systems are suitable even for those rooms in which children live. Installation work is carried out quickly and easy. The disadvantage of such systems is high prices.
  • Self.regulatory. Such designs are the most reliable, but also the most difficult. When the temperature becomes quite high on one or another section of the system, the wires control the resistance, so that heating elements do not overheat.

Cable devices are usually presented in the following types: mats, coils. Mat is a fiberglass grid, and there are wires in it. This grid can be cut, which is very convenient. especially in cases where it is necessary to install a warm floor in hard.to.reach areas. Thermal energy is formed from the incoming current. This is due to the heating elements that are under the flooring or in the screed.

Installation of the thermostat

If you approach the installation of a programmable thermostat with all responsibility, all the work can be done independently, without a specialist’s services. Before the installation, first of all, you need to familiarize yourself with the attached instructions, where the manufacturer indicated all the necessary information. Further determined with the location of the thermostat, based on its power and the power of the warm floor. The installation site should also be protected from thermal sources and direct sunlight. Having determined where the thermostat will be located, they begin to its installation, according to the following scheme:

In the chosen place, a niche is made in size and its box is installed.

Gently, without damage to the elements, a device is installed in the mounting box.

According to the color.intensive purposes, the wires are connected to the nests of the thermostat.

Last of all, the temperature sensor is connected to the product and the lid is closed.

Characteristics of a programmable thermostat

All types of thermal controllers for a warm floor are made to maintain a given temperature in the room. Therefore, their functions include, as the microclimate changes, turn on and off the heat supply for the room. The programmable thermostat differs from its analogues in that it is equipped with a digital processor, which is able to remember several values ​​at once. Thanks to this, he can serve several rooms at the same time, with different set temperature conditions. In addition, programmable thermostats have the following additional functions:

Thermostats are equipped with a contact for grounding. Some models of thermostats, without grounding are not turned on.

  • Fixation of the exact temperature of the floor. This feature allows you to combine heating systems with decorative flooring.
  • Ease of use. Data control and mode setting up are carried out both on the product and through Wi. FI or remote control.
  • Safety. The ability to set the exact minimum temperature, will not allow in the winter to freeze the heating system if the dwelling is left unattended.
  • Saving. The thermostat independently turns on and offs the heating of the floor, which to save on electricity consumption up to 20%.

The location of the device in the room

It is worth noting that programmable thermostats have a long operational period. But not the correct connection to the warm floor, can adversely affect their functional characteristics.

Installation of a thermostat

To save electricity and more rational work of the warm floor, the thermostat should be used. It must be installed before laying heating elements. It is mounted in a convenient place, retreating from the floor at least 30 cm. In the wall, you need to make a niche to install the box and draw a strob to the base of the floor, in which a corrugation or pipe is placed. The corrugation should pass on the base of the floor another 0.5–1 m, the connecting wires are placed in it from heating elements.

A competent place to install a thermostat

The ends of the cable should be brought to the thermostat so that the couplings remain in the screed.

Cabling

There are several options for laying cables:

Options for laying heating cables

The layout scheme of a snail me is popular, especially if resistive elements are used. The step between the turns is selected independently, depending on the required power of 1 m2. The minimum permissible distance is 5 cm, the maximum is 30 cm.

How can you calculate the required amount of wire per 1 m2?

  • Firstly, it should be determined whether it will be the main heating in the room or auxiliary. If the main one, then it is necessary to provide a power of 150 watts and above, and when the warm floor will be only an additional system. 110 watts will be enough.
  • Secondly, the degree of floor insulation is taken into account-if it is an apartment of the first floor, then you need to provide 140-150 watts, even with an additional heating. On the balcony or loggia, more powerful elements should be installed. up to 180 watts.
  • Thirdly, the determination of heated area is approximately 70% of the floor, while the location of the furniture is taken into account (the wire is not laid under it).

Now you can calculate the length of the cable. For example, the coverage area 10m2, it is necessary to organize a power of 140 watts per 1m2. There is a heating cable for a warm floor with a capacity of 16 watts. We calculate the maximum consumption: 14010 = 1400 watts. Determine the length of the cable: 1400/16 = 87.5 m. Now you need to choose such a number of bays or sections that are as close as possible to this value, since it is very problematic to shorten the heating cable for a warm floor.
