Basic or additional heating system " warm floor" is gaining increasing popularity among owners of urban apartments. This is not surprising - the presence of well-mounted and regulated heating of the floor surface gives the many advantages.

How to install a warm floor

How to install a warm floor

This approach allows you to feel much less dependent on the central utilities, which, it's not a secret, the beginning of the heating season does not always coincide with the onset of cold weather." Warm floors" provide uniform heating without creating horizontal convection currents, which often cause unpleasant drafts. is created is the distribution of the temperature in the vertical direction - the main heat in the area of ​​the legs with a gradual decrease as the height increases. There is the possibility of creating zones with more or less heating, depending on the specific purpose of the premises. How to install the warm floor yourself: is it possible, how similar is the process with is false, in which order the

- is performed answers to these questions and will be discussed in this publication.

The variety of floor heating schemes is large enough, but according to the basic principle of heat transfer can be divided into two large groups:

1. "Water warm floors » - as it is clear from the name itself, it is a system of pipes with circulating coolant, placed in the thickness of the floor. The fluid used for heat transfer is heated in an autonomous heating system, the of the connected to the boiler of that or other type , or from the central heating network. One can even find references to the connection of water circuits to the hot water supply system, naturally, if constant circulation is provided in it.

However, for urban flats of multi-storey development, since the article goes about them, such a floor heating system is not the optimal solution for several reasons:

  • Connection to the central heating circuit will require mandatory coordination with the organizations responsible for housing and communal services. And it's far from the fact that such permission will be received - of the calculated boiler capacity may not be enough for the to provide additional points of consumption, and the temperature drop in the heating pipes can cause justified complaints from neighbors around the house.
  • Providing the correct and for uniform circulation of coolant through the pipes " warm floor" will require the installation of a rather cumbersome and complicated in the adjustment of the distribution manifold with pumping equipment, which in close urban conditions is not always possible.

  • Water " warm floors" always require a thick enough( at least 50 mm) and a massive concrete screed. This can cause unacceptable additional loads on the floor slabs not provided for in the building project. In addition, height ties plus with with loy binding insulation will significantly raise the floor surface, and in a standard city apartment with this especially "do not run up."
  • And, finally, we can not discount the fact that pipes embedded in the floor surface are a potential source of leaks with very unpleasant consequences. Even visually notice the accident will not be easy, especially - quickly its to eliminate. As a result, , there is a possibility of flooding the lower neighbors.

Water heating of the floors will be more appropriate in a country house where a completely autonomous heating system has been created and is being installed, and an emergency with a pipe will not cause anyone, except for the owners of the , any trouble. However, this is a personal decision of each apartment owner, and if it is decided to dwell on this option, you can find out more about such warm floors in the corresponding publication of our portal .

2. For an apartment in a multi-storey building, the best option is to use electric " warm floor" :

  • Such floors are more profitable from the point of view of safety - there is practically no risk of causing any inconvenience or trouble to neighbors.
  • The installation of such a heating does not require any of the coordinating measures - the main thing is that a power line of the appropriate power is laid.
  • It does not require such a thick layer of screed, and with some types of " warm floor" it does not need at all. There is obvious saving of "precious" centimeters of the floor level.
  • No complex control cabinets are required - control and adjustments are made from compact panels that are comparable in size to a conventional switch. The accuracy and speed of the adjustments is much higher than that of the "water" floors. The presence of an electronic thermostat allows achieving significant savings - on the surface there will always be a preset temperature controlled by a thermal sensor, and the control unit will switch on and off the heating as needed.

  • Installation of such systems warm floor - is much simpler, less is laborious and not so expensive.
  • If the installation and connection are carried out according to all the rules, is purchased with high-quality material, then such " warm floor" will truly serve for a very long time - the terms are calculated in decades.

Electric floor heating systems are represented by several varieties:

  • Heating cables, which are laid on a pre-term insulated surface, and then closed with a concrete screed - the base for laying the finish coat.
Heating cables are usually installed under the screed

Heating cables are usually installed under the screed

The cables themselves can also seriously differ:

a) Single-core cables of the usual resistive action - the heat is generated behind the account of the internal electrical resistance of the conductor, as well as the usual heating coils.

Scheme of a single-core cable device

Diagram of a single-core cable device

The heating part of the cable is enclosed in a powerful double-layer insulation, between which layers additional screening copper protection is laid. At both ends, cable is connected with special sealed couplings with "cold" wires, which serve to connect to the terminals of the terminal box and practically do not heat up during operation.

Such heating cables are the most inexpensive, but have one serious inconvenience. When arranging them on the of the floor surface, it is necessary to take into account that both ends must converge at one point - in the place of installation of the thermostat. In words - it's easy, but in fact, can cause serious problems. And still one significant drawback - the cable warms the same throughout its valley, quite uneconomically spending energy.

b ) From Technological point of view it is much more convenient in operation two-core resistive cables .

As the heating element in such cables can be used as both veins, and only one, and the second in this case serves only as a conductor. In any case, the closed circuit is provided by the presence of an end clutch, in which a bridge is provided connecting the two conductors. As a rule, the cables are sold with a clutch, already installed in the factory, which ensures full sealing of the contact.

With a two-wire cable, the installation of the "warm floor" is simplified

The internal structure differs from the single-core of the presence of more of one layer of insulation on each of the conductors, excluding short-circuit. The "cold" mounting end of such a cable is one, and this seriously simplifies the process of laying it on the floor surface. However, the price of such heating cables is higher.

c) If is to be judged from the standpoint of the economy of operation, then the optimal choice is self-regulating two-wire cable .It has a completely different structure and uses a different heating principle.

The principle of the self-regulating cable

The principle of operation of the self-regulating cable

The two conductors are also enclosed in double insulation and copper with the shielded layer. However, between the cores there is an electrical connection in the form of a semiconductor matrix, the passage of the electric current through which causes the heating of the cable. But most importantly - not even that. Specially selected matrix composition reacts sensitively to the temperature, changing the conductivity at each specific site along the entire length of the cable. In cold places, the conductivity and, consequently, the heating - the maximum( in the scheme 0 - the region A ).At the rise of the temperature of the matrix conductivity decreases( area in ) and when the reaches a certain heating temperature( area C ), the semiconductor "locks", practically stopping or minimizing the passage of electric current. Similarly, a constant self-regulation of the entire cable is carried out, ensuring uniformity of heating the entire floor surface with minimization of electricity consumption.

One more advantage of such cables - unlike of single-core or two-core resistive ones, which are usually realized in the form of finished products of a certain length, semiconductor can be cut into the required size - for this purpose special places cut with defined step( usually 250 or 500 mm).To install a simple end insulating sleeve in this case is quite simple - there are no electrical connections in it.

Such cables stand, of course, is not cheap, but the funds spent very soon will be justified by saving on paying bills for energy consumption.

  • Electric resistive heating mats is, in fact, too two-core heating cable, but only fixed with defined with a loop pitch on the fiberglass mesh base.
Mesh mats make installation easier

The mesh mats simplify the installation

Such a design gives several important advantages:

- The process of laying the heating elements on the of the floor surface is simplified - no additional parts are required for it. This, by the way, reflects on the overall height of the created "pie".

- The thickness of the screed can be reduced, and in some cases, for example, when laying tiles - there is a possibility in general do without filling the screed or leveling compound.

  • Electrical systems " warm floors" infrared principle of operation.

The main difference of these systems is in the way of energy transfer. The working elements are made of special materials, which , without heating themselves, create a powerful flow of infrared radiation, which transforms when exposed to opaque surfaces in thermal energy.

Infrared " warm floors" are represented by two varieties:

a) Film heating elements .Between the two strong layers of the transparent plastic film are copper conductor bars. They are connected together by parallel strips containing a carbon paste, which, when current flows, emits an infrared stream.

Ultra-thin film heaters for the "warm floor"

The thickness of such film elements - less than a millimeter, which is very convenient for their placement under floor coverings. No screed is required in principle, which greatly simplifies and speeds up installation of the "warm floor".Such film coatings are realized by the footprint, and it is always possible to select the necessary number in depending on the developed heating circuit.

) Rod infrared heating mats .In this case, parallel conductors have semiconductor carbon rods with a spacing of 100 mm from each other. The total width of this mat is 830 mm.

The parallel connection of the rod heaters ensures the system's operability even if one or more rods for some reason fail.

Such heaters have the property of self-regulation, similar to the one described above. This gives the possibility of free movement of large pieces of furniture in the insulated such system room - overheating and burnout of mats is not will occur , because in the case of a heat transfer violation, the heating elements in this place simply "zaprutsya" without any damage to the rest of the surfacesex.

The difference from film heaters, except, in fact, the design - rod mats always require the presence of screed thickness of 20 mm - without it process with the amoregulation will be broken. Without the screed, you can only lay ceramic tiles, but in this case the adhesive layer should have the same thickness.

How to calculate warm electric floor

Before undertaking the installation of the warm electric floor, and even the still before purchasing the necessary components, you need to carefully calculate its parameters. In this case, from the area of ​​the room in which the will be the floor heating system will be installed, and the from , will become whether similar heating is used for as main one or it is intended only to improve overall comfort level.

For calculation the following basic parameters of the required heating power per square meter of the total area of ​​the room are taken, with the standard height of the ceilings of the city apartment:

Location of the apartment "Warm floor" - the main heating source "Warm floor" - additional heating system
Apartment on the ground floor 180 W / m² 110 ÷ 130 W / m²
The apartment is located above the heated room 150 W / m² 100 ÷ 110 W / m²

However, do not forget that the heatingThe elements are not stacked on the entire surface. The values ​​shown in the table will be correct if the coverage area of ​​the with a warm floor is not less than 80% of the total surface area of ​​the room. Multiplying the area of ​​the room by these parameters, it is easy to calculate the required total heating capacity of the " warm floor".

What are the rules for placing electrical heating elements on a "warm floor":

Basic principles of styling

Basic principles for laying out the

  • laying scheme. It is never planned to lay any heaters, regardless of their type , under stationary furniture items( sofas, cabinets, chests of drawers, stands and t. .).In such areas, there is no normal heat exchange between the floor surface and the air, and this can cause overheating of the heating elements and their failure. And for the furniture itself, the overheating of its parts can not be of use.

Even if cables or mats with an internal self-regulation system are used, the which , in principle, is not afraid of overheating, all is equal to this rule - there is no point in wasting power and wasting money for the elements which in general will not take part in heating the room.

  • The distance from the nearest cable loops or heating mats to the boundary of the installation area( from internal walls or furniture) must be at least 50 ÷ 100 mm. Near the risers or permanently installed radiators, this distance increases to 100 ÷ 150 mm. A similar interval is maintained along the outer wall of the house - the massive external structure has an extremely large heat capacity , and a significant amount of electricity will be "wasted", reducing heating efficiency and increasing operating costs.
  • It is necessary to execute the graphic scheme - it will be required for further calculations of , and it will be a good help in carrying out installation work. It is necessary to immediately determine with the place of of the location of the control unit( thermostat).It is to this point that the "cold ends" of the heating elements should approach. The thermostat unit should be located in an open place so that there is a possibility of permanent visual inspection. Its distance from the floor surface must be at least 500 mm .

This location should also meet the possibilities of laying a separate power line to it from the distribution board with a mandatory ground loop. To use " warm floor" to connect the usual network outlets is strictly prohibited. On the switchboard, separate machines are installed for each connection point( if warm the floor is planned and several rooms).Ideally, a similar system should be equipped with an additional safety device - RCD .

  • If with heating mats or film elements everything in the of a particular is understandable, for a heating cable it will be necessary to determine its required length and step of laying the loops on the floor. The calculation is carried out according to the following procedure:

First you need to calculate how long the ( L) cable will be required to heat the room:

L = S × PS : Pk

- S - is the calculated room heating area, with of all the above rules;

- Ps - required specific power per unit area( indicated in the table above);

- Pk is the specific power of the heating cable, which must be specified in its technical documentation.

Having determined the length of the heating cable, it is possible to calculate basic interturn distance of its laying on the floor surface( laying step):

H = S × 100 : L

The value of all the letter symbols is already indicated above.

The value of the inter-turn distance will be obtained in centimeters. It should be adhered to when laying, but there is the possibility of a slight variation in one direction or another without exceeding the total length of the heating cable. So, if it is planned to create a zone of increased comfort - for example, in the places of traditional rest of family members or children's games, this distance can be somewhat reduced for account of proportional step increase at other less demanded sites.

Calculators calculating the length of the cable and the step of laying it

The calculation becomes simpler if the reader uses the built-in calculator - you just need to enter the available data and click the "Calculate" button:

Calculation of the length of the heating cable
Enter the requested values ​​and specify the planned functionality of the "warm floor".
Set the engine for the calculated heating cable laying area in sq. M.m.

Enter the specific heat output of the selected heating cable model( W / m)

The resulting cable length is approximate. On it you can pick up a branded kit with a cable that has the length closest to the result found. And it only remains to determine the laying pitch:

Enter the cable laying area
Enter the length of the selected heating cable kit
  • When planning the installation, it is necessary to take into account the fact that heating cables under no circumstances should intersect in the thickness of the floor. A similar requirement applies to any heating mats - even small overlaps are unacceptable. In the installation instructions, the minimum distance between adjacent mats must be specified. If there is no such information, then the clearance is taken to be equal to at least 50 mm.
  • When laying out the laying scheme, the location of the thermal sensor is also provided. It is located at a distance of 400 ÷ 500 mm from the boundary of the heating zone, placing the cable loops in the middle.
A sample of a thermal sensor

Thermal Sensor Installation Example If infrared heating mats are used, the sensor should be located at their center, on the black radiating band in the case of film elements, or between two heaters - with rod heaters.

Position the temperature sensor so that it is as close as possible to the thermostat block - it is forbidden to increase the standard wire coming from the sensor.

Installation of various types of electrical " warm floor "

Acquiring all the necessary for the " warm floor" system, in addition to the heaters themselves, it is necessary to provide components and additional materials for the assembly work:

  • a thermal sensor with a standard wire must be included. If not, then you need to purchase it separately.

  • Control and thermoregulation unit( thermostat).Also can be included in the package of delivery or be purchased separately. The variety of models is quite large - from the simplest ones with a mechanical regulator to equipped with liquid crystal screens and electronic adjustment elements. However, in both cases connection scheme and marking of the terminal they have about one.
The thermostat can be electromechanical or electronic

The thermostat can be electromechanical or electronic

  • The system " warm floor" must be laid on the pre- thermally insulated floor - so that the thermal energy does not go to unnecessary heating of the floor slabs. In most cases, it is recommended to lay heat-reflecting under the heating elements over the entire floor area of ​​the with foamed polyethylene foam with an upper foil layer.
  • If the heating cable is to be covered with a screed, then for giving the strength it is necessary to use reinforcing mesh, metal or polycarbonate.
  • To fix the cable in accordance with the layout scheme, it can be tied with clamps to the rebar or, which is much more convenient, to use special mounting rails. The of the above shows their approximate location - at a distance of 500 - 1000 mm from each other.
  • In order to compensate for the thermal expansion of the screed, a damper belt must be installed along the perimeter along all walls.

Installation of " warm floor" with heating cable

  • Work should start with cutting of vertical shroud in the wall from socket to install the thermostat to the floor surface. Dimensions - with the expectation that the corrugated tube Ø 16 mm and the "cold" ends of the cable fit freely there. Usually 20 × 20 mm is enough.
  • After preparing the floor surface( revision, minor repair of weak areas, cleaning from dirt and dust and priming), the thermo-reflective substrate is spread on on it .Strips are laid back and pasted with foil tape.
  • A damper tape is glued around the perimeter of the room. Its height should be 1 mm above the planned finish of the floor with considering the 30 mm of the required concrete screed.
  • The reinforcement grid is laid out on the floor surface, the mounting strips are installed and fixed.
  • The cable layout starts from the thermostat installation site( from of the shroud).The "cold" end should be freely accessible to the place of future switching with the control unit.
Cable laying with mounting rails

Cable laying with mounting rails

  • The cable is laid out in accordance with a preassembled scheme, fixing it to the reinforcing mesh with plastic clips and( or) to the mounting rails, which have for this purpose special flexible lobes. In some places where the loop tries to to go up , its can be fixed with a drop of silicone hotmelt .
Installation of a thermocouple in a corrugated tube

Installation of the temperature sensor in the corrugated tube

  • After the cable is completely laid, an corrugated tube is attached to the with a corrugated tube in which the temperature sensor will be placed. At the end of the tube must be installed plug. The arrangement of the sensor has already been discussed above. The tube with the sensor fits into the shroud .This arrangement of the sensor is necessary so that in the case of the output of the it is not necessary to demount the filled floor - it will be enough to pull the sensor out of the tube and install a new one in its place.
  • The next step is to check the electrical parameters of the cable laid.

- it is necessary to measure the insulation resistance. To do this, use a special device - a megger. Safety of operation will be ensured if the resistance is not less than 20 MΏ.

- conductivity of the cable is checked, ie .isolation of the electrical circuit, and resistance, which should not differ from the passport values ​​with a tolerance of 10% in either direction.

All wires are connected to the terminal block of the thermostat( of course, with the power supply switched off).The location of the contacts can differ slightly on different thermostats, but always it is accompanied by graphic and alphabetic symbols and it will be easy to understand. shows an example of this connection:

General scheme of "warm floor" layers with heating cable

  • In case when the is functioning properly, the power is switched off again and goes to the screed pouring. Install a beacon system with calculation of layer thickness of 30 mm. When concrete works are kept very carefully so as not to disturb the location of the cables.

Follow t carefully check the completeness of filling with a solution of all areas so that no voids remain. For better performance, it is better to use ready-mixed concrete with the addition of plasticizing and micro-reinforcing components.

Filling the screed over the laid cable

Filling the screed over the laid cable

  • The system is only allowed to operate after complete hardening of the filled coating - this depends on the characteristics of the solution used. The commissioning of the system should not be carried out immediately to the estimated capacity - this process should be extended to 2 - for 3 days with a gradual increase in the heating temperature of the cable.

Filled over warm floor screed will be the basis for laying any finish coat.

Mounting features using mesh heating mats

The design features of mesh resistive heating mats make it more convenient to lay them on the floor surface.

Laying the net mat

Laying of the

  • mesh mat The cable is already laid out in a loop-like with set, and the polycarbonate mesh base will become a good reinforcement for the screed.
The net can be trimmed to make turns

The net can be trimmed to perform the

  • rotations. In the process , the layout of the mats according to the scheme when the direction of the direction is changed can be pruned with scissors without violating the integrity of the cable itself.
  • The floor mats can be fixed to the floor surface with a silicone gun, "liquid nails" or on a strong building scotch.
  • In case assumes fill screed, the work on laying the heating elements differs little from the procedure for using a conventional cable, the only difference is that no mounting rails and additional reinforcement are required.
  • However, such mats can be used without screed, if they are to lay ceramic tiles. Here there are special features of the work:

- thermo reflective foil substrate is not used - it will not give a reliable adhesion of tile adhesive with an old coating.

- for the location of the corrugated tube with the temperature sensor, will have to cut an additional asdriver 20 × 20 mm in the floor surface, otherwise the corrugation will protrude above the surface of the mats.

Laying ceramic tiles directly on heating mats

Laying ceramic tiles directly on heating mats

- when laying the tiles directly on mats the adhesive layer is increased by 8 ÷ 10 mm.

  • The rest of the actions - switching the cable part, checking and commissioning are no different from those described above.

Features of mounting of infrared mats

As already mentioned, these mats have the ability to self-regulate, but this will only be possible if the conditions for their proper installation are met. These include the mandatory use of the thermo reflective substrate , and the presence of px st screed or layer of tile adhesive of the established thickness - 20 mm.

  • To install the temperature sensor in the right place in the floor surface, the shroud is made, into which the is plugged the from the end of the corrugated tube.
  • The substrate extends to the prepared and primed concrete floor surface. It should be as close as possible to the surface. Joints must be glued with foil tape.
  • The mats are laid out. On the turns, one of the live buses is cut in the set location, between the two adjacent rods.

Coupling of

  • padded mats The busbar's bus ends are connected with a mounting wire using a coupling crimp terminal with the obligatory double-layer insulated by heat shrink tubing. The mounting wires are also fixed to the surface of the tape.
  • To ensure the adhesion of the future screed or layer of tile adhesive to the floor in the thermally insulating substrate, rectangular "windows" are cut.
  • The heaters are connected to a thermostat and the system is operational.
  • Next, or poured screed thickness of 20 mm, or stacked ceramic tiles on a layer of glue of the same thickness. For screeds it is recommended to use special construction dry mixes designed specifically for warm floor.
  • After the screed is poured, further work on laying the finish coat is carried out not earlier than after 4 weeks.
  • Commissioning is carried out as , stepwise, with a gradual increase in temperature to of the calculated .
