Warm floor electric under the tile. Styling technology. Advantages and disadvantages. Cost of materials
The process of warming your home has been interested in people since ancient times. At the same time, with the advent of modern energy sources, completely new options for home improvement and heating began to emerge. Therefore, today a heated electric floor under the tile in the bathroom has become not only very popular, but is considered necessary.
Principle of operation and design
If we talk about electric systems, they can be divided into two types. The first of them uses the principle of active resistance, and the second is based on infrared radiation. Therefore, before acquiring a certain warm electric floor under the tile, it is necessary to examine both options and choose one of them.
Active resistance systems
Such designs are presented as a separate cable or wire, laid in a special substrate of the grid. The heating process is carried out due to the fact that when passing through this conductor an electric current heats it to a certain temperature. It depends on the mains voltage, which in turn is regulated by a special device.
Immediately it is worth noting that such a warm electric floor under the tile is laid quite often. The fact is that it has its own cross-sectional area, depending on the cable, which can be hidden in the solution during installation of the coating. Such systems are best used for installation directly into the screed or when using a thick layer of cement.
However, it should be noted that active resistance cannot be called economical. Such warm floors, electric prices are quite high, and if you take into account the high energy consumption and expensive installation, you can immediately find one of their biggest drawbacks.
These designs are presented in the form of metal plates, which are sealed in a plastic film and have the form of rolled materials.They are well protected from moisture and only a small section of the section fails during a physical breakdown. In this case, such a warm electric floor under the tile fits just perfect, because its thickness is less than a millimeter, and during installation you will not have to carry out additional work.
It is also important to mention that these products are considered the most economical. The energy consumption in them is minimal, which, combined with the relatively low price of the product itself, is quite convenient for people operating a small budget.
It is very important to remember that special models of such systems are created under the tile. They have peculiar cuts for a hitch of a floor with a finishing covering. Conventional films can cause certain installation problems.
Advantages and disadvantages
- Almost all the disadvantages of warm electric floors are that, unlike water systems of this type, they cannot be called economical. Even infrared types of devices with constant use can lead to significant costs. That is why they are resorted to only in those cases when it is impossible to use water heating.
- The biggest advantage of such devices is that they are very easy to install. Even a novice master can install a heated electric floor with his own hands without resorting to heat exchange formulas or contour calculations.
- With mechanical damage during operation there is no danger of flooding, and repairs can be performed independently. However, it will require the dismantling of the tile at that location.
- Typically, underfloor heating electrical reviews have the most positive. This is due to the simplicity of their operation and the ability to control the degree of heating up to a degree. This can not boast of water systems.
Select a specific model
All heated floors have relatively low electric prices. At the same time there is just a huge number of models that differ in their parameters and appearance. Considering this, it is simply not worthwhile to recommend a specific type of such systems, but if the installation will be done personally, then you should pay attention to the finished systems, as they say - out of the box.
They are sold with all the necessary elements and can be assembled in a few minutes.At the same time, manufacturers of such products produce them on the basis of a certain quadrature. This allows you to create a warm electric floor with their own hands, even a beginner.
Professional craftsmen usually advise to use infrared-type film products for such works, since they are rather thin and protected from moisture. At the same time, it is necessary to purchase carbon-based products for tiles, as it does not corrode if damaged, unlike bimetallic heaters. However, it is easier to work with mesh-based mats.
The installation process of such systems can be divided into several stages. However, some of them depend on the initial state of the surface. Also, each specific model may have its own characteristics, which also need to be considered in order to get the best electric floor heating with maximum efficiency.
The floor for installation must be perfectly level. Some instructions for specific models allow small drops of 5 mm per square meter. However, it is best to install the electric floor heating only after leveling.
If the drops on the surface are small and there is no desire to spend time waiting for the cement mortar to dry, then it is worth using leveling mixtures. They are quite easy to use and create an almost perfect surface.
It is important to mention that under heating the screed may expand and as a result, defects will appear. Therefore, before its manufacture on the perimeter of the walls is installed damper tape. It compensates for the expansion factor.
Any installation of electric floor heating involves the installation of insulation. This is not done in order to obstruct the cold air coming from below, but in order to maintain the temperature inside the room. The fact is that you need to warm the surface itself, and not the stove under it.
Given this, for such work it is worth choosing a heater with an additional layer of reflective material. Lay it so that the reflector was on top, that is, beat off infrared radiation, which give out electric underfloor heating. Prices for such products are quite high, but you should not save on this.
Professionals recommend using thin foam with an additional foil coating as a heat insulation material.At the same time, there are such models that were specifically designed for this purpose, and their reverse side has applied glue for easy fixing.
Further installation is that it is necessary to lay the heating elements in the film or mesh on the surface. This is done in accordance with the instructions for the selected model. If infrared elements are used, they can be fixed with a special adhesive tape, and the heating cable on the grid can be clamped with a stapler.
Typical installation of electric floor heating assumes that the entire surface will be covered. However, if it is necessary to create only a specific zone, then the heaters are placed on an area that is 5 cm more on each side.
All heating mats or film are arranged so that they do not overlap each other. In this case, the joints are sealed using a special tape with a reflective surface. It can also be used to fix all the necessary elements.
Next, you need to install a thermocouple or other device designed to measure the temperature, if it is provided for in a particular model.Usually it is mounted in the center of the room or in the most important place of the site. In this case, the conductor retraction is made on the same side with which the power is connected to the heating elements.
All wires entering outside should be placed in a special protection located in the place of installation of the tile. This is necessary so that when the coating expands as a result of heating, it will not damage them. Therefore, special adapters are always included in the kit for such systems.
The control system at this stage can not be installed, but be sure to make a test connection and run a test for performance. At the same time, further installation can be performed only after complete heating of the heating elements occurs.
At the final stage, it is necessary to lay the tile itself. Moreover, if it is mounted on film, then first it is necessary to shoot the grid, which is fixed with scotch tape. For mats with cable, you can not do this.
It does not make sense to describe the technology of tile installation, since it has no particular differences. The main thing is to leave a gap between the wall and the coating of at least 5 mm.This compensates for expansion with increasing temperature.
After all you need to connect the control device that will control the electric underfloor heating. User reviews agree that it should be located near the entrance to the room at the level of switches. The connection of wires and thermocouples perform according to the scheme, which is attached to the selected model.
You can start the device only after the seams on the tile are frozen. Otherwise, damage will be inflicted on the final coating, which will appear only during operation. Given this, it is worth waiting a couple of days, after which, and turn on the heat.
