An additional source of heat in a private home can be called an electric warm floor. A well-thought-out selection of the heating mat and the purchased complete system from the manufacturer will facilitate the laying of the floor. It remains only to properly lay the finish floor covering in the form of tiles and you can winter safely!

What type of floor under the tile to choose
The accessibility of the installation and connection of a warm electric floor allows the use of laminate, parquet and tiles for the finish coat. The algorithm of work and the technology of laying the warm floor of electric under the tile is similar to the traditional method.
Recall that the main stages of laying are:
• preparation of the base of the floor
• installation of the thermostat in the rated location
• laying the electrical cable and its connection
• Layout of the underfloor heating system according to the installation scheme
• application of adhesive solution for subsequent laying of tiles.
Naturally, the question arises: "Electric warm floors under the tiles, which ones to connect?".
Helpful Tips
To realize the device of system of a warm floor it is possible with application of a single-core, two-wire and ultrathin cable (mat). The cable is laid at the system device and connected by means of a thermostat. An obligatory condition is the installation of a single-core or two-wire cable in the screed.
Experts advise choosing an electric floor consisting of heating mats. When installing the underfloor heating system with your own hands, no sand and cement screed is required from the heating mats. Polymer-mesh base mat with a thin cable creates increased strength of the warm floor and reliability of insulation.
The upper hard layer of the tile does not have a powerful effect on the floor system. When installing, it is important to correctly calculate the laying area of the mat.
Calculations of parameters and selection of elements of the system when laying the warm floor under the tile
calculation of the area under the warm floor from the mats of electrical
To calculate the area necessary for laying the floor of mats use a simple formula:
S styling = S total - S meb
Let's remind, that the system of a warm floor of an electric do not have under large furniture and the established home appliances.
To determine the length of the heating mat, it is necessary to divide the obtained area by the width of the selected mat. For reference: the width of the heating mat is in most cases 50 cm.
It is recommended to buy a warm floor under the tile, complete with the manufacturer.
The complete set of the model range of the underfloor heating system from the manufacturer contains: a heating cable on the mesh, a set of wires and plastic clips intended for fixing the lead wire, installation and installation instructions. It does not hurt to also get feedback on laying the electric floor warm under the tile.
choose a heating mat and a thermostat
A universal option for choosing heating mats for laying under the tile or porcelain tiles for living spaces can be called an element that meets the following parameters:
• power supply voltage 220-240V
• specific power from 145 to 160 W / m²
• width of the mat from 48 to 50 cm with the length of the supply cable 4 m
• cable diameter from 3.25 mm.
• with a minimum bending radius of the heating cable up to 30 mm
• with an adhesive mesh, which ensures better adhesion of the mat to the heated surface when laying the finish coat.
For example, a heating mat for placing under ceramic and granite tiles ThinMat power 145 W / m² (220V) with a diameter of heating cable 2.85 mm will provide comfortable conditions. The heating mat is designed for the subsequent laying of tiles on tile adhesive.
The thermostat is preferable to choose a programmable one with the available possibility of setting the required temperature regime.
Own laying of the warm floor
installation of heating mats, their connection and insulation testing
After purchasing the "Warm Floor" system kit from the manufacturer, it is necessary to read the enclosed instruction. The mat with the heating cable, placed on the transparent grid in turns, must be spread out on the prepared floor surface. To do this, it is recommended to compose a layout scheme on paper, according to which we will lay the mat.
After this, it is necessary to loosen the mat and cut the mesh, without touching the heating cable, on the linen. Canvases can be laid out on the stripes with a turn of the direction. You can fix the stripes with an ordinary tape.
It is not recommended to use thermal insulation on laying, where the coating can crack.
Notching the fixing tape, the cable is separated from the mesh. If you change the direction of the mat, you must follow the values of the minimum radius of bending and distance, and if necessary, you can change the pitch of the loops. The metal corrugated tube into which the supply cable will be placed should be placed between the hinges.
A smooth bend is possible between the corrugated pipe, the wall and the floor. Install the heating sensor after laying the tube. After laying the mat and installing the corrugated tube, it is necessary to check the resistance of their insulation.
laying the tile on an electric floor
After checking the reliability of insulation of heating mats and before starting work, prepare the adhesive solution in the traditional way, using the manufacturer's recommendations.
The finished glutinous mixture must have a uniform consistency without lumps. The glue is applied using a notched trowel on a small area of the floor.
The thickness of the layer can reach 1-2 cm. Naturally, it should be borne in mind that the floor level after laying the tile will increase by 1.5 cm, including the thickness of the adhesive layer and the thickness of the tile. Tiles from porcelain tiles or tiles laid in place and slightly pressed into the glue solution. For a smooth seam between tiles, remote crosses are recommended. To make the tiles drowned in the adhesive tightly, you can use a rubber mallet to work.
Laying the tile layer starts from the most visible angle of the room. From the edge of the wall to the laid tiles, it is recommended to leave a small gap of 2-3 mm. Grout the joints after the final drying of the solution under the tile (an average of 24 hours). Interlace stitches are cleaned from the remnants of the adhesive composition, then they are applied to the grout using diagonal movements using a rubber spatula.
