first step. Disassemble the old flooring and screed.When the packing film underfloor heating the old tie, if it

is normal, you can not dismount.In the case of installation of the cable system on the tie will have to get rid of.Thoroughly cleanse the surface from dust and dirt.

second step. laid a layer of waterproofing material.Traditionally used polyethylene film, but you can choose and other isolation, if desired.It is important that the material Weatherproof sign on the wall by approximately 100-120 mm.

third step. around the base is fixed to the wall damping tape.Thanks to this will be provided by the system compensating for thermal expansion during heating.Excess sealing and damping tape cut cleanly.

Film and Tape damper

fourth step. Puts insulating layer.Thanks to him, will be excluded loss of heat through the base.Insulation choose, taking into account the features of the room location, type of substrate and the target destination of the heating system.

If you plan to use the system as a supplement to the main heating, heat insulation can be done with the use of polyethylene foam fitted with a reflective layer foiled.In addition, the material will take over the function of the substrate under floor heating.

If the lower floor there is a heated room, it is best to equip thermal insulation using expanded polystyrene sheet.The thickness of the material -. 2-5 cm Suitable insulator and another with the same thickness.

When installing the heating system in an unheated room earlier, for example, on the veranda or balcony, insulating layer should be more thorough.For example, well-suited 10-cm polystyrene foam insulation or mineral wool of the same thickness.

fifth step.On insulation laid reinforcing mesh.Optionally, add in microfiber coupler solution and a plasticizer.This improvement will allow the staff to do without additional reinforcement.

Above the insulation is laid reinforcing mesh and installed beacons for screed

first step. Choose place the thermostat installation.Its installation is recommended to perform a 15-cm space from the floor surface.

second step. charts the heating installation.

Important: the film can not be placed under a large household appliances, furniture and other heavy items.

In preparing the plan, consider the following important details:

  • the first row of the film should be laid indented at least 100 mm and not more than 400 mm from the wall;
  • if floor heating is used as the main heating system, it should take at least 70-75% of the total surface area;
  • if the infrared film is placed as a supplement to existing heating systems, rather, that it takes about 40-50% of the base.

install and connect

first step system. Spread infrared film over the insulation.Stick Charting.If necessary, the film can be cut at the factory lines.

Laying copper elements perform frequent contacts down towards the wall with the thermostat.

second step. Connect the terminals to the edge of the copper strips and connected wire.

third step. us isolate places cuts infrared film and connection clamps and cables.To isolate suitable special bitumen mastic.

Important: the longer the heating cloth, the less should be the contacts.Remember: the band can not be longer than 8 m

Some clips install on the current-carrying surface..The rest is located inside the heating film.

Proper installation of wires

Correct laying wires

fourth step. Connect the sensor to the bottom of the infrared film and carefully isolate it.

fifth step. Set the thermostat.Before that, laying all the planned material and connected all the contacts and the cables must be completed.The thermostat is recommended to be installed permanently.In the absence of such a possibility you can plug it into a power outlet, as an ordinary appliance.

Set the thermostat

Set the thermostat

By experience, the bulk of the cables connecting the thermostat and a heating film, it is best to lay under the baseboard.

Finally, connect the system to the mains and turn it to the test.

Test the system after installation

Explore the behavior of the system after turning on the network.If heat, sparks, and other defects not, everything is fine.You can start the installation of the finish flooring.Before this system is sufficient to cover tightly with plastic wrap, but some experts still recommend to pour a thin layer of screed - it topcoat lies more accurately.

first step. Set the thermostat to a pre-prepared wiring box.Summing box to the power and ground cables.Down from the wall of the box do recess for connection with the heating wire.

second step. Prepare a scheme of laying the cable floor heating.You can do this step first, as you like.On paper, mark the space for laying the heating cable.At the site of the future installation of heavy furniture and appliances cable does not fit.

Calculators calculating the length of the heating cable and its laying step

for proper preparation of the scheme need to know two values ​​- the total length of the cable and its laying step (distance between adjacent wires in the loop).There are special formulas, but we offer the built-in calculator.Enter values ​​and get the result!

Baseline:

- the total area of ​​sites premises to which the cable will be laid;

- particularly space - select from the proposed list;

- specific power cable - it is stated in the data sheet, watts per meter.

length Calculation of the heating cable
Enter the requested value and specify the planned functionality of "warm floor".
Install engine calculate the area of ​​laying the heating cable into the square.m.
Select the functional purpose of "warm floor"
main source of heating.Sex on the ground or above unheated rooms main source of heating.Downstairs is located a heated room additional heating source.Sex on the ground or above unheated spaces Additional heating source.Downstairs is located a heated room
Enter passport value

specific heat capacity of the chosen model of the heating cable (W / m) value found will determine the choice of a set of floor heatingcable, the length of which is suitable to the maximum extent to the calculated parameter.

Now, knowing the length, it is easy to calculate and stacking step:

again enter the cable stowage area
Enter the length of the selected set of the heating cable

third step. transferred from the paper on the basis of the scheme.To label useful scotch bright.If you wish, you can familiarize yourself with ready schemes presented in open sources, and focus on them during operation.

fourth step. Puts floor heating cable along the lines of markup.

Important: the cable can not bend.

To attach the cable to the reinforcing grid, laid on top of the insulation layer, using the same clip or special tape.

heating cable to connect the power cable and a temperature sensor on a flat surface.Necessarily Cover the place of the corrugated pipe connections.

Check cable resistance.Valid values ​​are specified in the instructions to the system, specify this point in a separate order.

Finally will be connected a power cable to the product.Pre disable the supply of electricity.After connecting the system to the thermostat test it in several modes.If all goes well, we proceed to further action.

Ties are best done from a special ready mix.The packaging of this composition will indicate that it is designed specifically for use in combination with underfloor heating.The mixture cook according to the instructions.Sufficient thickness - 40-50 mm.

evenly distribute the mixture over the surface with a spatula.Make sure the cable under the body did not have air pockets.Because of them, heating quality will deteriorate considerably.Let the screed dry completely.

Important: Infrared Heated floor and require different time on "exposure" after installation.Using film floor can be within 2-3 days (if not poured screed).Cable the system it is necessary to stand for 3-4 weeks.

Finish laid in accordance with the installation of the technology selected material.Most often placed on top of a warm floor tiles and laminate.You can also put the parquet, and even linoleum.and you can use other coating if desired.Focus on your preference, the interior space and the available budget.
