How to make an electric floor heating laminate ?

We have already discussed with your underfloor heating installation under tiles, which were used termomat and heating cable.In the case of laminate and parquet board it is recommended to use a more modern and efficient heater - IR film.laying of floor heating film technology is quite simple, and now for the readers' electrician himself "will be given detailed instructions with video tutorials!

Determine the kind of heater

Laying the floor covering

Recently we looked at types of electric underfloor heating, where a little concerned on the use of various heaters for tile and wood flooring.

In the case of the wooden floor use heating mats and cables are not recommended for the following reasons:

  1. Electrical conductors are evenly radiate heat, which adversely affects the wood.
  2. heating electric cable (or mat) consume more electricity, so from the cost savings stacking film warm floor, again, he wins.
  3. to cover the presence of infrared concrete tie is optional, can not be said about the alternatives.
  4. film thickness of less than a millimeter, which will save the height of the ceiling after installation.In the case of an electrical conductor due to ceiling height screed may shrink up to 10 cm.
  5. Because the laminate has a low thermal conductivity, use heating cable is not recommended.This is due to the fact that the conductor first heats the screed, which transfers heat to the floor covering already.As a result of the heat exchange efficiency is lower than the infrared radiation, which immediately warms all the objects in the room.

heating Efficiency

It is for these reasons that the film used blow warm floor under laminate and parquet board.

Prepare all necessary materials

At this stage it is necessary to carry out the calculation of infrared warm floor under the laminate to determine the right amount of all materials.Estimated often quite simple, you need only count the useful area of ​​the room, and taking into account the selected heater power, and calculate its area.

So, in order to facilitate the perception of information, present all the points:

  1. Determine the useful area of ​​the room.Lay the material should be a minimum distance of 15 cm from the wall, and under heavy furniture and appliances to lay the film is prohibited.Based on these requirements, we create a diagram and determine the usable area.
  2. Select the capacity of the system.Generally, for use underfloor heating coating 150 W / m2 of power (in the event that there is no central heating) and 90 W / m2 in the building if there is a heating system.It is also possible to choose intermediate values, based on their own conditions of use.
  3. We count the number of films.To do this, the usable area is multiplied by the power that you have chosen.For example, floor heating capacity of 2250 W (15 * 150) is required for the room of 15 m2 without central heating.We go to the store and buy a roll of the right size.

also need to purchase an additional insulation (best penofol), foil and adhesive tape foamed polyvinyl film (surface protection against mechanical damage of the heater).

When all materials will be counted and bought, you can start the installation process.

carry out installation work

Technology laying film warm floor under the laminate consists of several stages:

  • surface preparation;
  • insulation base;
  • flooring material;
  • finish laminate.

draw your attention to the fact that this technology is used in the case of the floorboard, and the installation is carried out in a similar way!

Prepare surface

At this stage it is necessary to remove the old finish flooring, remove all debris and view the status of the concrete screed.It is necessary that the surface is smooth, with no chips or cracks.Otherwise it is necessary to pour the dirty tie, which will remove all defects.

The prepared surface

Immediately it should be noted that in rooms with high humidity (in the unheated loggia or in the bath) to carry out stacking infrared coating is strictly prohibited.If the humidity is small, in addition you need to take care of high-quality waterproofing overlap!


insulation to the heat goes up (in the room) and not down (on the ground floor or in the basement), you need to take care of high-quality thermal insulation of the base film under floor heating.To do this it is best to use penofol.The material is thin, so the ceiling height does not significantly change after installation.penofol

Since one of the parties penofol adhesive, difficulties in the insulation should arise.The joints between the sheets need to seal with tape foiled.

Bonding joints with tape penofol

Flooring film

Now, when the foundation will be completely ready, you can safely proceed to the laying film warm floor under the laminate by hand.

Stacking sheets butt

According to the scheme you have to spread out the material on the surface.If you need to cut a certain piece, do it in the appropriate places.

note several requirements for laying film warm floor under the laminate:
  • prohibited to lay the sheets overlap, only the butt joint;
  • sheets should be positioned so that the contacts are facing the wall on which the thermostat is set;
  • copper side should be at the bottom (adjacent to the base).

Next, set the thermostat at a suitable place.It is better to do it in Stroebe on the wall, next to the outlets (for easy connection to the network).Setting the thermostat

Thereafter, the film is connected to the thermostat by means of contact wires that are clamped with special clips.Clamp for connection to the network

should also be noted that all the clamping area and separate sections of material it is necessary to insulate the bitumen insulation!

Insulation clamp

From the thermostat is necessary to bring the temperature sensor, which is connected to the underside of the film coating.For this purpose, a special basis Stroebe, not longer than 30 cm. The sensor is placed in a protective corrugated and is established under the sheet heater.Be sure to enclose a sensor layer of insulation, otherwise the measurement accuracy noticeable error may occur, which affect the efficiency of the system.You can connect the film warm floor under the laminate without thermostat, but in this case, the power consumption will increase, and the control of temperature conditions will be completely absent.Connecting the temperature sensor

When all contacts are connected and insulated, you can proceed to a control check.To do this, we turn the thermostat to the network and make sure that the entire surface is evenly heated.It is also advisable to check for compliance with the multimeter cover of the passport with the real resistance (value must not exceed the difference of 10%).

If everything is correct, on top of a warm floor can be laid a protective polyvinyl foam tape and start decorating the surface of the floorboard or laminate."Пирог" системы

Useful tips from the masters

To simplify the process andto make the film a warm laminate flooring more durable, offer to your attention a few helpful tips:

  1. Place the sensor near the cold wall to carry out the regulation and control is the coldest point of the room.
  2. In no case do not mount the heater sheet nails or screws, asThis can cause system failure.Use only foil adhesive tape.
  3. Infrared film is easily damaged by mechanical action (if heavy furniture will put pressure on it).Make sure that under any heavy objects the heater was not.
  4. By choosing laminate film warm floor taken seriously.Not everyone can function normally with a floor heating system.Those models, which are intended for heating, have the appropriate logo: marking logo
  5. Make sure that the floor is not other heaters (eg oil heater) have been installed.Otherwise, overheating may occur film and its failure.One coating
  6. interval should not be longer than 15 meters.
  7. sure to perform grounding of the heater.To do this, on the perimeter and diagonal seal the foil tape, which the other end is connected to a grounding terminal.
  8. laying Do not make a film underfloor heating at temperatures below zero.
  9. Check your home's electrical wiring, so that it can withstand the load of this heating system.If it turns out that the RCD, circuit breaker and conductor diameter wires are not suitable, replace all of the elements for more powerful.

That's the whole technique of laying a warm film floor under a laminate with his own hands!As you can see, the installation is quite labor intensive, but still under the power of even a person who does not have the relevant experience.
