Selecting a heating system for a particular room

Equipment Direct stationary electric heating can be divided into four groups: wall-mounted heaters, ceiling mounted infrared (IR), long-wave heaters, cable and film system for heating floors and ceilings, as well as regulating thermostats and programming device. Heaters is a device in a protective and decorative metal casing, which has two groups of openings: at the bottom for entry of cold air from above, to exit the hot air. Inside there is a tubular heating element (heater), a prisoner, as a rule, ceramics, and placed in a steel tube with a radiator. Convector is placed on a special frame, which is four screws attached to the wall. Manufacturers produce a wide range of convectors in the power range from 500 to 3000 watts weight 2,8-9,2 kg. The heating element of long-wavelength infrared ceiling heater, located inside the device transfers heat to the surface of special materials that provide an intense infrared radiation. The opposite side has a heat-insulating layer and the attachment system to the ceiling. For dwellings with ceilings 2,4-3,2 m using low-temperature devices with capacity of 250-300 W/m2 of surface radiation temperature 80-120 ° C. For rooms with ceilings from 3.5 to 10 m using devices with a surface temperature of 300-900 ° C. Underfloor heating cable on the basis of now well known in Russia, while regulating heating film material has a rarity. Their basis is a polyester film with a thickness of about 100 microns, which caused heating graphite conductor. These films can be mounted in the ceiling and the floor under the parquet and laminated board. Controls direct stationary electric heating allow you to adjust the thermal regime in each room. They enable programming of temperature, taking into account the schedule of real demand for heating, saving 25-80% of electricity. Selection of equipment for specific premises variety of equipment for PSEO allows you to make the best choices for each room depending on its functional purpose. Thus, for the hall, corridors and staircases make better use of heaters - the most inexpensive and simple equipment to be mounted. Bathroom, toilet, sauna, a kitchen can be fitted with water proof convectors, floor heating. For bedrooms and nurseries will approach the long-wavelength infrared ceiling heaters, which are simultaneously warm the floor, the carpet on it, and bed. The living and dining rooms are best combined coil and infrared panel. This allows you to create zones of increased thermal comfort. In the winter gardens and similar areas are recommended to set the infrared heaters, which create a natural microclimate for plants and save energy. If a house or apartment found freezing, soaking or wetting the walls, then get help from all of the same infrared heaters that transfer heat objects more efficient than other types of heaters. They are also suitable for heating glass surfaces (windows, stained glass, etc.) to protect them from ice and snow. In detached low-rise buildings is difficult to ensure a comfortable warmth on the ground floor or basement: in an unheated basement floor of the first floor will be cold (at 15-16 ° C) even at fairly high temperature in the room (air temperature difference between floor and ceiling may reach 5-7 ° C). Address this shortcoming can only be through the floor heating or infrared heaters in combination with good insulation. In a small country house, usually set the oven. In the middle band is the most economical heating equipment. However, it has several disadvantages, chief among them - space heating only the area around the furnace (other separate spaces require additional heating). Another disadvantage of stove heating - large fluctuations in temperature in a heated room during the day (sometimes up to 10 ° C). The third major flaw in it - always cold floor. This is due to the fact that as a result of convection (which is based, and furnace heating), hot air is concentrated at the top and unheated basement cools the floor. With a significant freezing at home (at subzero temperatures in the room) must use the stove more than 10-12 hours, and is not conducive to rest and proper operation of the building. All these drawbacks are eliminated electric heating. To stabilize the temperature of the room with the stove and protection from freezing when the oven is not fired, the required power can be reduced by half. Cold floor will disappear when mounted on the ceiling infrared heaters. The cottages with traditional heating (with gas and liquid fuel boilers), there is a substantial likelihood of triggering protective automation as a result of a temporary power failure, low gas pressure, breakdown of a pump or fan, etc. This will disable the entire heating system. If you can not quickly solve the problem, or you are currently absent, the stationary electric heating will give you back heating in the critical areas to activate the main heating system. Typically, this is a toilet, bathroom, kitchen, ie those areas where there are water slide, freezing which can lead to emergency situations. In this case the electric heating installed in the minimum mode is disabled when operating the main system. Power heaters can be reduced by 2-2,5 times against the settlement. The additional cost of such redundancy compared to the main heating system will be 3-5%, while operating costs are absent. Another possible use of convectors in the cottages of this class is heating remote areas, where the lead pipe is irrational and unjustifiable, as well as in bathrooms and showers for the rapid temporary rise in temperature. Economy, ecology, safety benefits PSEO country house can be seen already in the process of acquiring the equipment, which costs around 5-10 $ / m2 heated area. The cost of installation is approximately 20% of the cost of equipment. Virtually no costs for prevention and maintenance and operating costs are very flexibly adjusted depending on the mode of operation of the building and specific needs for warmth. Installation (except for the floor heating cable) runs in a day or two, it be able to spend any technically competent person. Ability to save power when the equipment PSEO depends on the duration (frequency) of its use: in the winter or summer, for permanent residence or a day or two a week. At constant human habitation in the nighttime temperature in the rooms can be reduced by 3-4 ° C, in the free areas - at 7-10 ° C. In the daytime, in unused rooms optimum reduction temperature 5-7 ° C. Compared with traditional heating systems with electric boilers PSEO allows you to save 30-40% on energy. If a country house used to stay in the winter, only two or three days a week, with direct electrical heating energy costs decline by 60-80%. This is due to ease off seldom-used upper floors. In the traditional heating similar disconnect lead to significant problems caused by imbalance of fluid flows and temperature regimes. In a heated room with a water gate (kitchens, toilets, etc.) shall be established and monitored up to 0,5 ° C minimum temperature of +5 ° C. Traditional heating do not allow it. This temperature makes it possible to relatively quickly warm up the room, promotes long-term operation supporting structures of the building, prevents condensation and mildew and, ultimately, significantly prolongs the life of a country house before the next overhaul. Stationary electric heating does not require maintenance, are excluded accidental leakage. When disconnecting the power supply all modern systems that do not have backup power sources are disabled. Typically, the home of stored heat is sufficient for 20-30 hours, and the restoration of power supply must be carried out much earlier. PSEO starts working immediately after the power supply without external human intervention. Traditional heating must be run manually. Interesting possibilities for exploitation PSEO provide software tools control heating mode. You can program a week schedule of hourly temperatures in each room with built-in clock: at given lower or raise temperature levels. With proper installation of automatic disconnection and short circuit protective device (RCD) on the leakage current excluded the possibility of fire or electric shock. All types of heating, except electric, in one way or another polluting. Ventilation pumps and lead to additional noise and vibration. Leakage of gas and diesel fuel, coal dust adversely affect humans. In addition, the risk of fire or emergency situations in systems with liquid and gaseous fuels is much higher than electric heating. Modern electric heating does not burn oxygen, dust particles, not desiccate the air. Radiant infrared heaters and underfloor heating will create convection currents of air and dust. Electromagnetic interferences arising during their operation, meet European standards and much lower than in many household appliances. No doubt that eventually this kind of heating will be in the Russian country houses as usual, how common it is today in the cottages in foreign countries.
