Thermoregulators (thermostats) are designed to control thermal processes in various fields of activity. The main advantage of programmable thermostats is the ability to set the temperature for a long period (week). The system will automatically lower the temperature by 5 °C at night or reduce it to a minimum during the day on weekdays when the owners are at work, reaching the set temperature immediately upon their arrival. This allows you to significantly reduce electricity consumption.
The screed (concrete layer) is usually made from cement-sand mixture (plaster mix) of the M-150 brand and similar, with the addition of 1 kg of plasticizers per 1 bag of the mix. Its curing time is 28 days. You can also use a special mix "Pobedit - Warm Floor" that has a small linear expansion when heated with a curing time of 14 days before turning on the system.
electronic thermostats installed in the rooms control the heating of the cable in accordance with the set temperature of the floor and air, automatically maintaining it with an accuracy of 0.4 ° C, programmable thermostats can maintain the temperature regime you set in the room in accordance with the program for a week; the cost of the cable system is significantly lower, its installation requires much less labor and time; there is no need for system maintenance throughout the entire service life, for example, for heating using radiators and pipes in the floor for cottages, it will be necessary to use an antifreeze, not water, otherwise the system may freeze in winter (during a long absence of the owners) and the floor will be damaged by the expansion of water; the need to conduct hot water supply under the floor throughout the apartment is associated with additional costs during construction and a decrease in the height of the room by 7 cm, which increases the load on the interfloor ceilings. And in the case of electric floors by 3-4 cm. in the case of the room being far from the hot water riser, the costs of laying communications and additional pumps (pressure boosters) will be significantly higher than when installing an electric floor, for which only 220 Volts are sufficient (there is no need to specially supply electricity from the panel, since the system power is, on average, 120 Watts/sq.m.
In case of mechanical damage to the heating cable and failure to comply with basic measures for operating the system.
The principle of operation of the electric "warm floor" is based on the automatic maintenance of a set temperature in the room by the thermostat. The source of heat in the system is a heating cable laid on the floor and filled with cement-sand mortar, which turns the floor into a large working panel, evenly distributing heat. The concrete screed accumulates and transfers heat from the cable to the room.
The built-in electric heating system can serve as the main heating system of your home. Heating the floor (room), maintaining the set temperature and creating comfortable conditions is its main task.
The system consists of a heating cable laid in the concrete floor screed and an electric thermostat that connects the cable to the power grid in accordance with a specified operating program, thereby maintaining the required temperature in the room, as well as mounting guides. This design is called a low-temperature heating panel.
Cable heating systems are safe and "cause" less harm to health than electrical wiring hidden in the walls and floor of the house. The system provides soft and even heat, does not create drafts, maintains natural air humidity, automatically maintains a comfortable temperature in each room separately. Deviations from the natural electromagnetic background of the Earth associated with the use of "warm floors" are several dozen times lower than the maximum permissible levels of radiation of all standards.
In a room with cable heating systems, uniform heat distribution is achieved regardless of the height, which ensures the greatest comfort in the heated room, the popular wisdom "keep your feet warm and your head cold" is put into practice, there are no strong ascending (convective) air flows constantly mixing dust, which significantly improves the hygienic characteristics of the room; there are no costs for technical maintenance of the heating system - the "turn it on and forget it" principle, full automation of temperature control in each room at any time of the day; reliability of the heating system, service life comparable to the service life of the building (structure).
A comfortable temperature on the floor surface is a temperature that is 2-3 degrees higher than the room temperature.
Yes, it is possible. This is determined by the presence of a screen (grounding circuit) on the cable and the tightness of the connecting sleeves.
The human foot feels comfortable at a floor temperature of +21°C. International standards indicate that the most comfortable floor temperature is within the range of +19…+26°C. Higher or lower temperatures are considered uncomfortable.
Conventional heating systems are usually a limited area surface that creates a flow of hot air. It rises to the ceiling, where it cools down, and then goes down cooled. The room is not heated evenly, and convection flows occur – the cause of drafts that cause colds and allergies. In the case of a cable heating system, there is no temperature difference between the head and foot levels. The floor temperature exceeds the air temperature by only 2-3 °C, creating an optimal thermal regime for a person. The possibility of overheating is excluded, so the air always remains fresh, with natural humidity. The cable heating system is controlled by electronic thermostats specially designed for this purpose, equipped with various types of temperature sensors, which maintain the specified temperature regime.
The system's power consumption directly depends on the mode of use, on the thermal insulation of the ceiling and the room, on the set temperature that the cable heating system must maintain in the room. For an indoor room with thermal insulation, with comfortable heating, the power consumption will correspond to 10-30% of the nominal power of the cable.
If the installed power of the heated floor in the apartment is equal to 150-180 W per 1 sq. m of the room area, then additional heaters will not be needed in winter, even if the central heating pipes do not heat well.
It is possible to use a cable heating system under linoleum, laminate, carpet and ceramic coatings, provided that the coating thickness is no more than 10 mm. It is necessary to know the technical characteristics of the coatings, permissible temperatures and relative humidity in the room, acceptable for these coatings.
Theoretically, yes. But in this case, you will have to take on the functions of the thermostat and manually turn on and off the "warm floor" system when the most comfortable temperature for you is reached. It is not recommended to use the system without a thermostat also for reasons of energy saving.
If the area to be heated is large and two or more cable heating systems need to be installed on it, it is advisable (but not necessary) to select heating cable brands of the same power. The connection between them is parallel. It is advisable to start laying out all systems from one point.
It is not recommended to use one thermostat for several rooms, because heat loss in different rooms is different, and the temperature sensor of the thermostat (built-in or portable) can be located only in one of the rooms. For example, heating systems are installed in the kitchen and in the bathroom. The cables are connected in parallel to one thermostat, the sensor of which is located in the kitchen. The thermostat maintains the set temperature, taking into account all heat input from sunlight, electrical appliances, the hot water supply system and heat emitted by people. The temperature regime favorable for the kitchen, in this case, may be simply cold for the bathroom, or vice versa. An exception may be, for example, refrigeration chambers, in which it is necessary to maintain the same temperature regime.
No. It is necessary to take into account all the features of the room. For comfortable heating, both radiators and floors are needed.
Yes, you can. But you need to know that the installation of the system affects its performance, despite all the apparent simplicity at this stage. Therefore, you should entrust this work to professionals.
The level of thermal comfort in each room is determined by the correct calculation of heat loss (this parameter is calculated at the design stage) and the system control equipment (thermostats, timers).
The service life of a cable floor heating system is equal to the service life of the building where the heated room is located. The approximate period is 70 years.
poor thermal insulation of the room and drafts, even minimal ones greatly reduce the floor temperature, especially in winter; reduced (increased) voltage in the network; total thickness of the screed; distance between cable turns;
