Electric floor heating: energy consumption. How to save on electricity consumption?

With the onset of cold weather, every owner of an apartment or house tries to find the most profitable way to effectively heat a home. которым может быть очень экономным. In the last few years, the electric warm floor has become popular , the energy consumption of which can be very economical. For this, several expert advice should be considered when installing and operating the system. This will reduce the cost of the family budget for energy.

Device of the system

, в первую очередь следует изучить устройство системы. To understand how to save on the consumption of electrical energy , first of all you should study the device of the system. For heating inside or outside the room, special wires are most often used. They consist of nichrome veins. Around it there are several insulating shells.

The device is connected to a thermostat that controls the heating level. The economics of this system is connected with its basic principle of work.

будет меньше, чем у конвектора или радиатора. Electricity consumption of the warm floor will be less than that of the convector or radiator. He peak temperature is determined at the base of the room. Cold masses are at the top. Convectors, radiators, on the contrary, create a maximum of temperatures at the ceiling. In the area of the first 50 cm from the floor heating is minimal.

Varieties of systems

Will help to understand the features that have an electric floor heating, characteristics. у всех систем неодинаков. The energy consumption of all systems is not the same. On sale are cable, mounted under the screed (3-5 cm), and mat, which is installed directly in the tile adhesive (5-8 mm). There are other systems.

The cable is on sale in the form of a bay. Its cross section is about 7 mm. Therefore, it must be filled with a screed. The master independently places the heating wire on the prepared surface. The laying distance between the turns can be from 8 to 15 cm. Therefore, the capacity per 1 m² varies from the density of the turns.

The mat is a mesh made of PVC material (50 cm wide), on which a thin wire (3 mm thick) has already been laid out. Here the capacity of 1 m² is installed by the manufacturer. Therefore, when buying, you must choose the right option.

System power

Regardless of the type of system, there are certain norms regarding which the system capacity per 1 m² is selected. For a room heating system from 110 to 180 W / m² is suitable. By installing an anti-icing system for sidewalks, roofs, gutters, etc., a wire with a capacity of about 200-350 W / m² is required.

The choice of this indicator also depends on the floor covering. которого равен 110-130 Вт/м² в час, подходит для ламината, паркетной доски. Electric floor heating, the energy consumption of which is 110-130 W / m² per hour, suitable for laminate, parquet board. Wood coating can not be heated more than 30 ° C. Therefore, the power of such coatings is not required too high. Tile tiles want to heat more. Therefore, it uses systems from 150 to 180 W / m² per hour.

Infrared warm floor

Today, infrared warm floor electric is widely used . этой системы отличается от кабельных разновидностей отопительных приборов. The power consumption of this system is different from the cable types of heating appliances. The heating element of such an article looks like a film with stripes. It is a laminated carbon paste.

Such a warm floor is suitable for "dry" installation, when the solution is not used. On the film without screed or tile adhesive immediately mounted laminate, linoleum or carpet.

The power of the infrared warm floor is higher than that of the cable. It is about 220 W / m² per hour. This product is better used for comfortable heating.

Power calculation

There is a certain technique that allows you to calculate how much energy is consumed by the warm floor. расчета очень простая. The calculation formula is very simple. Initially, the required capacity of the system per 1 m² is to be determined according to the methodology presented above.

Then calculate the area on which the warm floor will be laid. You can make comfortable heating and heat the room with additional appliances. In this case, the system covers less than 50% of the area of the room. Wishing to heat a room exclusively with an electric warm floor, it is necessary to mount the system not less than 70% of the base.

We will admit, it is necessary to make independent heating in a bathroom which is on 3 floor of the many-storeyed house. The required capacity per 1 m² is 150 W (the flooring will be made of tiles). The area of the room is 10 m². If you take away the quadrature, which is occupied by furniture and plumbing, it turns out 7 m². The calculation is made:

M = 7 * 150 = 1050 W

You need to buy a 1050W system.

How much energy does the system consume?

The above calculation method allows you to find the maximum power consumption of the warm floor. But under ordinary conditions, such systems consume much less energy.

The fact is that the operating temperature of the wire is usually 65 ° C. The surface to this level never heats up because of the mandatory presence of heat loss in the room. But with prolonged operation, the system can reach 50-55 ° C on the floor covering. It is comfortable for a person to stand barefoot on the surface at a temperature of 25-30 ° C. Therefore, the temperature of the heated floor is controlled by the thermostat.

The system uses the most energy for the first heating. If the wire is mounted in a screed, this process takes about 3-4 hours. For the mat, the first warm-up lasts from 40 minutes. Up to 1 hour. Then the thermostat turns off the current supply to the wire. Screed can give off heat for a long time. On the surface, the temperature can not drop more than an hour. Mat cools down for 20-30 minutes. During this time, the floor does not consume electricity.

On average, the electric heated floor works for 8-10 hours per day, provided that there are no significant heat losses in the room and the heating level is 25 ° С.

How to reduce power consumption during installation?

которым можно существенно снизить, требует правильного подхода к проведению его монтажа. Electrical warm floor, energy consumption that can be significantly reduced, requires a proper approach to its installation. The better the floor is insulated, the less owners will pay the bills for energy.

Be sure to insulate the base in the premises of the first floor, on the balcony. For this, polystyrene or rubber-based roll insulation is used. Filling the cable with a screed, it will also be better to equip quality insulation.

Mat because of the small thickness of the solution above the wire can be mounted without a heater, but only if it is not the first floor.

In a room with high ceilings, large window openings, poorly insulated walls, more energy is required for the presented system.

How to reduce energy costs after installation?

которым зависит от особенностей помещения, также сильно зависит от типа терморегулятора. Warm floor electric, the energy consumption which depends on the features of the room, also depends heavily on the type of thermostat. On sale there are mechanical and programmable varieties. In the first case, the device constantly maintains a given heating level, breaking the circuit when a certain temperature is reached.

The programmable thermostat will reduce energy consumption by up to 30%. This device allows you to exploit the warm floor only in those hours when the owners are at home. After they leave, for example, the program reduces the heating to a minimum level. An hour before the arrival of the owners the device switches on the system and heats the floor again.

которым зависит от множества факторов, каждый пользователь сможет значительно сократить затраты на оплату счетов за энергоресурсы. Considering such a system as electric floor heating, energy consumption that depends on many factors, each user can significantly reduce the cost of paying bills for energy.
