Climatic conditions in Russia imply high heating costs in the winter. Modern manufacturers offer an innovative heating device PLEN. It is characterized by improved heat dissipation and economical energy consumption.
What is a plan system
PLEN heating is a wide strip of a special film in which resistors are sealed. The width of the strip is 5-6 meters. For ease of installation, the device is divided into parts that can be cut off. Moreover, the functionality of the system is not violated. The width of the paintings can also be different. Usually mounted options with an indicator of 0.5 or 1 meter.
The temperature rise of heated objects is realized by infrared radiation emanating from the elements. The end result is provided by passing current through a resistive device.
The electric film heater is mounted in a ceiling structure or under the floor. The radiation passes through a decorative coating, providing heating of the floor, furniture and other objects in the room. The heat carrier is equipped with a temperature sensor. Upon reaching a certain temperature in the room, he turns off the device, which saves energy.
Principle of operation
The basis of the system is the use of physical heat transfer processes. The device has a multilayer structure. An aluminum foil is laid between the layers of the lavsan, the function of which is the reflection of heat. Resistive elements are mounted in the foil layers. The thickness of the heaters is 1 - 1.2 mm. Lavsan films have two functions: electrically insulating and decorative.
When connected to electricity, current flows to resistive elements. The foil reflects infrared radiation with a length of 9.4 micrometers. The waves are invisible, but heat emanates from them. The maximum temperature of the device is 45 ° C.
The temperature distribution depends on the power indicator of the device. When set to a temperature of + 45 ° C, the floor will heat up to + 22 ° C. In the middle of the room, the air temperature will be + 18 ° С. The ceiling height of the room does not matter.
Safety
The claim that heating is harmful to humans is unfounded. The intensity of heat transfer at the units is not so high, since at a temperature of 45 ° C it is compensated by 80% of the area of the heated room. With this temperature indicator, the electric heater propagates long infrared radiation.
According to medical experts, the heat generated by the device is comfortable for the human body and does not cause any side effects. In operation, the system operates 6-10 minutes per hour. The floor warms up, and the air temperature in the region of the head remains within the optimal range. Thus, the impact on humans is short-term.
Safety PLEN confirmed by a large number of certificates. The device is allowed to be mounted in children's and medical institutions.
Advantages and disadvantages of film heating
PLEN heaters are characterized by silent operation. Throughout the entire period of operation, the installation does not require additional maintenance.
The main advantages of the device include:
- Profitability.The money costs for an electric heater, supplies and installation are much lower than when installing other heating systems.
- No risk of fire. The device does not contain moving parts. Conductors and thermocouples are sealed in a dielectric layer. The use of a heater is permissible in wooden buildings.
- Reducing the content of dust particles in a heated room. PLEN does not create convection of warm air flows, like batteries.
- Durability. The warranty period is 25 years, and the service life is 50 years.
- Rational use of space. The thickness of the device does not exceed 1.5 mm. Mounted inside ceilings, under floor coverings and behind decorative panels.
- Ease of Management. Programmable controllers and temperature sensors are mounted in the device.
- Comfortable microclimate. The humidity level in the room remains within the optimal range.
- Uniform heat distribution.
The disadvantages of the device include:
- the inability to use indoors with such decorative finishes as plaster, paint or trellis;
- the presence of a good electrical wiring or a separate line;
- fragility of the system.
In the case of the installation of the PLENA, it becomes necessary to conduct high-quality thermal insulation. Vapor barrier membranes and windproof films are used. And this is an extra cost.
Criterias of choice
Before buying a device, you should plan a place for its installation. It is recommended to purchase models with a temperature sensor, as they are distinguished by a high level of security.
When choosing, the following indicators are taken into account:
- power;
- voltage;
- weight;
- maximum temperature of the heated surface.
The amount of energy that is required for heating determines the height of the room. Professionals do not recommend mounting an electric heater on a ceiling with a height of more than 3.5 m. In this case, heating costs increase.
When buying a unit, you should contact a specialist who will select the optimal model of the device based on the parameters of the room and the installation location.
Mounting options for film heaters
It is recommended to install the PLEN film heater on a flat surface. In practice, it is mounted on the ceiling or floor. Despite the different locations, the heat distribution is the same for the ceiling and floor models.
It is not recommended to carry out wall mounting, since the heat transfer coefficient is reduced: warm flows rise upward, limiting the heating of the room.
Floor placement of PLEN
Film heating is fixed for all types of floor structures. After switching on, the device begins to quickly warm the floor. Warm air rushes up, giving way to cold. The highest temperature will be on the floor surface and slightly lower - at the level of the head.
Features of floor mounting include:
- Lack of reliability of flooring. The design may be disturbed by pointed parts of the floor, massive furniture, etc. It is recommended to lay an additional protective layer for the heating film.
- The electric heater may become deformed when heavy household appliances or furniture are in the room. It is not recommended to lay the film under these items.
The floor mounting has an undeniable plus. This installation method ensures the absence of the influence of infrared radiation on furniture and household appliances.
Ceiling Plane
Ceiling mounting is very popular. When you turn on the device, infrared rays are directed down to the floor, which absorbs them.
The advantages of a ceiling installation include:
- uniform heating of the room;
- creating optimal conditions for the body;
- low risk of damage.
The disadvantages include:
- installation complexity;
- the influence of infrared rays on household appliances;
- risk of water leaking from neighbors.
During installation, any coating is allowed. The exception is stretch and fabric ceilings. These materials may warp from heat fluxes.
Price of heaters
The price of a heating plan depends on the average electricity consumption per 12 square meters. m. area. The power indicator varies in the range of 15-20 W / hour. The cost is determined by the area and power level of the film. On average, the price is 1200 rubles per square meter.
Also, the price segment is determined by such indicators as installation specifics, optimal conditions of use and protection characteristics. For example, depending on the presence or absence of dust protection, the system is divided into 2 categories: premium class IP-67, the cost of which is 1230 rubles, and economy class IP-54 at a price of 1150 rubles per square meter. The cost of a heating film for a sauna is 1359 rubles. The IP-67 model is able to heat wet rooms, as it has a high level of protection against water.
Acquisition and installation pays off within 2 years. Operation does not require expenses. Payment of electricity bills will not be so high with the optimal setup of the device.
