To warm the room by using the stove or fireplace, electric heaters, the system "warm floor". You can also apply to traditional and proven in practice by individual hydraulic systems, heating systems, which are based on the boiler. Properly designed boiler will provide enough heat even when severe frosts, and in transitional periods of the year can reduce power to an optimal value. Power - the most important characteristic of any boiler required to heat (usually specified in kilowatts), the exact calculation, which can be fulfilled only engineer heating engineer. However, there is tentative, the available non-specialist ratio: 10 m2 for heating a well insulated room with a ceiling height of 3 m required about 1 kW of power. For example, for heating the cottage area of ??250 m2 will need a boiler capacity of 25 kW. Depending on the energy consumption, there are several types of boilers: gas, liquid fuel, solid fuel, electric. In this paper we consider the gas and electric wall hung boilers. Such boilers in heating systems have appeared recently, but have already gained great popularity. Typically, this type of equipment called a "mini-boiler." This term is not used by accident, because in a small package is not only a burner, heat exchanger and a control unit, but, in most models, one or two of the circulation pump, expansion tank, pressure gauge, thermometer, a system that provides safe operation of the boiler, and many others elements without which it can not do work a normal boiler. Consider the cases in which optimal use of wall hung boilers. First of all, is the creation of individual heating systems in country houses and cottages, given that the power of these devices ranges from 12 to 42 kW (depending on manufacturer and grade of the boiler). Another significant advantage - ease of installation. Some buyers believe that the ease of installation - a plus, which only applies to installers. It's not quite true, because the amount you will pay for the installation of the wall of the boiler or boiler installation, where the separately installed boiler, boiler, pumps, expansion tank, etc., differs very much. Compactness and the possibility to enter wall-mounted boiler almost any interior - another advantage of this type of boilers. Gas wall boilers. By the method of removing waste gases can be divided into a model with natural and forced draft. Boilers with natural draft used a comparatively long time, but the models with forced draft worth discussing in some detail. Such models have many advantages for installation and operation. They remove waste gases occurs by a fan built into the boiler. These boilers are ideal for rooms without a traditional chimney, since the products of combustion in this case are derived through a special coaxial flue, for which only enough to make a hole in the wall. Coaxial flue still often referred to as "pipe in pipe". On the inner tube of the flue combustion products are displayed on the street by a fan, and the external air enters. In addition, these boilers do not burn oxygen in the room, do not require additional flow of cold air into the building from the street to maintain the combustion process can reduce the investment to install, since it does not need to make expensive traditional chimney - instead it has been successfully used short and cheap coax. Wall-hung gas boilers can be either single-circuit (only work on heating) and double-circuit (except for heating and provide hot water supply). It should be noted that most of the wall boilers equipped with devices allowing their safe use. Thus, the flame sensor with the loss of his stops the supply of gas, locking thermostat with emergency increase in water temperature in the boiler shuts it down, a special device and the boiler at a power failure, another device blocks the boiler off the gas. Present and the device off the boiler at reducing the amount of fluid is below normal, and the traction control sensor. Promising area of ??wall-hung gas boiler is a per-apartment heating in multi-story urban homes. Today much is said about the reform of housing and communal services. One of the key issues of the reform - the creation of efficient heating systems. Repair of old worn-out requires a significant amount of heating. In addition, the heat loss during its delivery to every apartment in an old heating mains are large enough. In these circumstances, the best may be to apply the per-apartment heating based on wall-hung gas boilers. Calculations show that this will reduce the cost of gas (compared with the existing central heating) by about a factor of 2, and the cost of the concrete consumer of heating could be reduced by 2-3 times. Reduce costs - not only the dignity of every apartment heating. Having your own boiler, the owner who decides when and what the temperature in the apartment he wanted to support. After all familiar with the situation where central heating is included ahead of time, and people open the window, to "remove" excess heat. In this case all relate to heat as a stranger, for which is still paid a fixed amount. Nobody wants to be more precise - could not save him. Second, even more unpleasant situation, when the central heating switched late, and people are freezing in their apartments. If you have your own boiler such problems can not be. Another direction of wall-hung gas boilers - replacement of old housing stock is morally and physically obsolete gas columns in the double-circuit boilers. This will not only improve the supply residents with hot water, but also create individual heating system. Electric wall-hung boilers are quite simple and, therefore, quite reliable design. The main elements of electric boilers is a heat exchanger consisting of a tank with reinforced in him heaters (heating elements), and a control and regulation. When you install electric boilers not so stringent as when using a gas boiler. Eliminates the need for a special boiler and chimney. Electric boilers are compact and quiet. They do not require major maintenance and easy to use. It is obvious that the electric boilers - is not only a set of virtues. There are significant drawbacks, limiting the spread of this type TEPLOAGREGAT. First of all, not everywhere have the opportunity to allocate required to heat your home electrical power. Second, the relatively high cost of electricity. Thirdly, Russia is not rare power failures. True, when possible power outages, electric boiler is often used in conjunction with a solid backup. This same option applies to saving energy (first house a heated using cheap solid fuel, and then in automatic mode, the temperature is maintained by electric boilers). Importantly, low-power electric boilers are in two different versions - single-phase (220 V) and three-phase (380 V). Boilers over 12 kW are usually made only three phase. The vast majority of electric boilers with capacity of 6 kW is produced multi-step, allowing efficient use of electricity and does not include the boiler at full capacity during the transition periods - spring and fall. Given the high cost of electricity, the major problem is its rational use in the operation of electric boilers. What should we do to avoid paying too much in the operation? First, as much as possible to warm the room. Second, significant power savings can be obtained by installing remote software devices that support the indoor temperature to a predetermined schedule you. For example, if a house was missing from 8.00 to 19.00, with the help of programmer you can order to maintain the boiler at this time we assume the temperature 14 ° C, and the arrival of the hosts to warm the room up to 21 ° C. Besides saving energy, programmers noticeably increase comfort and ease of use of heating equipment. Essential when using electric heaters is their safety. Electric boilers are equipped with the necessary safety elements: safety valve, temperature limiter and automatic air valve. In addition, the control unit monitors the water flow in its value system and with its fall will turn off the power of the heating elements.
