Popular models of cable electric floors
Such heating elements are designed specifically for installation in a cement-sand screed and are suitable for premises of various purposes. The possibility of a one-way power connection greatly simplifies the arrangement of a warm floor. The standard delivery set (regardless of the manufacturer) includes:
- the cable itself (the total power depends on its length, and as a result, the area of the heated room);
- connecting and end couplings;
- a special mounting tape with fastening tabs for the cable, located at the same distance from each other, and holes for fixing to the subfloor;
- wire for power connection;
- piece of corrugated insulating tube for installation in the screed temperature sensor.
The rating of warm electric floors is headed by the ETC 2-17-400 model from the well-known Swedish manufacturer Electrolux worth 5300-5500 rubles. The length of the heating element is 23.5 m (with a diameter of 4.5 mm), the power is 400 watts. Of the design features, it is worth noting a three-layer insulation that can withstand up to 4000 V for breaking through, and a braided copper screen. The outer protective shell is resistant to the chemical composition of any grade of concrete. Manufacturer's warranty - 20 years.
A set of underfloor heating from the German manufacturer Aura Heating KTA 32-500 with a length of 32 meters, a power of 500 W and a cost of 3600-3800 rubles is confidently located on the middle line of the tournament table.

Advantages and disadvantages of underfloor heating
The undoubted advantages of underfloor heating are:
Uniform distribution of heat from bottom to top over the entire area of the room
Complete autonomy, that is, independence from the central heating system, which is especially important for maintaining a comfortable temperature during the so-called off-season period. Possibility of adjustments depending on the wishes and preferences of the user
Unlike standard radiators, a warm floor is absolutely invisible in the interior and does not affect the overall design of the room.
A few disadvantages include:
- financial costs for the arrangement;
- the possibility of installation only during the repair of the apartment or the change of flooring.
The best film infrared heat-insulated floors
This variety is designed for laying under light floor coverings: parquet board, laminate, parquet, linoleum, carpet. Installation is carried out without arranging the screed in a dry way. Such products are most in demand among the owners of city apartments as additional heating (especially during the heating off period).
The rating of film underfloor heating manufacturers is headed by the South Korean company Caleo. The Gold model with a power density of 170 W/m² is equipped with the patented Gridiron-S mesh, which prevents unwanted sparking between the heating elements and the copper bar. The thickness of the film is 0.4 mm, the cutting step is 20 cm. In addition to the roll of the infrared thermal element itself, the delivery set includes contact clamps, electrical wires and special bituminous insulation. Automatic reduction in electricity consumption by 1.5-2 times (the so-called self-regulation effect) with an increase in floor temperature can significantly save electricity costs. The price is about 1900-2000 rubles per 1 m², the guarantee is 15 years. For poorly heated rooms, you can purchase infrared film with a specific power of 230 W / m². However, it will also cost more.
