HEATING SYSTEM WITH ELECTRIC BOILER.Electric boiler. Usage electric boilers in the heating system is a very good alternative to gas boilers.Electric boilers can be used as a primary source, as well as an additional source of heating homes andresidential facilities.Many people think that the use of electric boilers are very expensive. Because the cost of electricityincreases with time. But the maintenance costs of electric boilers are practically equal to expenditure onmaintenance of gas boilers. But for gas boilers need to equip the chimney. The advantages of electricboilers offset the cost of electrical energy. For ease of operation of electric heating is heating onlycompetitor in the gas from the pipeline. But it wins at installation time and the amount of spending onequipment and installation of heating systems.Also, the use of electric boilers will save you in the construction of communications. On theconstruction of buildings with forced ventilation. As well as making records. The use of electric boilersdo not pollute the air from coal dust and the smell of burning gas and diesel fuel. The likelihood of firesor other emergencies in comparison with the gaseous fuel is much less.
An important parameter in the selection of an electric boiler is its small capacity boilers power. Electricmade - single phase (220V) and three-phase (380 V). Boilers, in which an output exceeding 12 kWthree-phase are. Most electric boilers, power with more than 6 kW - a multi-stage boilers, giving theopportunity to save energy. They are not included in the total power in the off season - spring and fall.Electric boilers are classified according to the power to: Condos up to 9 kW; cottage up to 30 kW; Semi 60-70 kW; industrial to 200-300 kW.Http://www.heatlinkusa.com/Electric boilers in terms of technical equipment and complete separation of the following groups: Economy - These devices consist of hydro, which has heating elements and simple automation ofelectromechanical thermostat. To reduce the size of the boiler, pump placed outside the boiler body.Electric boilers of this group are designed for operation in the heating system with natural or forcedcirculation of coolant. Design of body parts in them simplified. Standard - electric boilers are equipped with several degrees of protection, and the circulation pump,located inside the boiler. These boilers have a beautiful design. Premium - an important feature of this class of devices is the availability of electronic securitysystems and temperature control, as well as the ability to connect to a centralized system of regulationof the micro-climate. The device is made from the original design of the cabinet.Heating electric boilers are usually made wall. Only when a power of 20 kW - floor. Produce electricboilers and double-circuit single-circuit. The latter are used to provide simultaneous heating andproviding hot water.Electric boiler inside view. Electric boilers have certain advantages.Low cost, because they are cheaper, similar in power solid or gas boilers. Simple design and operation,as electric boilers have compact dimensions and low weight. They are environmentally friendly, do notemit harmful substances, and they are technically safe. Electric boilers do not require complex care,and operation is very simple. They are equipped with built-in automatic control systems andmaintaining a certain temperature. Electric boilers produce simple and modern design. Currently,electric boilers can have from one to four stages of power regulation. Regulated may be in manual andautomatic modes. A degree of equipment of electric boilers these controls, management and securitysystem manufacturers place a fairly wide range, so the selection of the boiler, pay attention to it.The disadvantage of electric boilers is dependent on the cost of electricity and the lack of sufficientcapacity in some remote villages. To connect the electrical wiring of the boiler requires enhanced,while for large power boilers - three phase 380 V. In the case of a large consumer of electricity, thevoltage may drop, leading to an increase in current, and this may affect the serviceability ofautomation.When choosing an electric boiler heating area must be considered. Power of electric boiler is selected
on the basis of about 1 kW to 10 sq.m. well-insulated house, where the ceiling height of 3 m most usedare the double-circuit electric wall boilers 6-15 kW, and among the household - floor electric boilers20-30 kW, which are used for houses.Placing Electric boiler. Electric boilers at a cost not very expensive. And because they are moreaffordable compared to other boilers for heating. In terms of volume and weight, they are verycompact, and setting them takes a lot of time and is quite simple. Because of their size is not large, sothey are placed mainly on the wall. They can be placed in small rooms. Electric boilers do not require aprofessional and easy to care and service they are quite simple. Current models are equipped with built-in automatic systems of control of the boiler. Electric boilers are simple in appearance and have amodern design. They are made from environmentally friendly materials, and these boilers do not have aharmful impact on the environment and people. They are more secure from the boiler, in which there isan open combustion chamber.Electric boilers have an efficiency of 100%, and it does not decrease during the whole period ofoperation. Unlike gas and boilers and boilers for solid fuels, which will eventually lose their efficiencyup to 50%. The degree of electrical equipment of boiler control and safety elements can be quite broad.Therefore, when choosing an electric boiler is needed to pay attention. The process of power control ofelectric boiler can occur in an automatic or manual modes. Electric heating systems require almost nomaintenance.In the application of electric boilers in the heating system to heat an average of one cubic meter. areaconsumed from 4 to 8 watts of electricity per hour. But if you payment system for electricity, you cansave this money. A very effective and economically beneficial, the combined heating system, such as agas boiler and electric boiler, solid fuel boiler and electric boiler. This enables users to reduce the costof natural gas within the limited costs of consumption and provide ease of use solid fuel boilers atdifferent times of the day.You can save money and in this way: use payment system for electricity and heat storage method isused when the tariff is low, for example, to heat large quantities of water for domestic hot water. If youuse the counters and switches the room temperature, it is possible at this save up to 30% of electricenergy by maintaining the desired temperature in the house during the day.The electric boiler is recommended not to put in a house with an area greater than 100 square meters,because of its power may not be enough. Also, it will consume a lot of electricity, which can not sustainthe network. Therefore, an electric kettle can be placed in such homes, as an emergency so as not toleave the house with no heat at all, if will not work for some reason the main boiler.Electric boilers are divided depending on the heating element to: electrode, and (with a tubular electricheater).Electric boilers.How it works tankless electric boilers is to transfer heat from a tubular heater (heating element) to thecoolant - antifreeze and water. The advantage of such boilers is that their fuel elements are not incontact with the coolant. Power of electric boilers does not depend on the type and temperature of thecoolant. Therefore, these boilers used stepwise or gradual adjustment that minimizes the voltage dropswhen you turn on or turn off electric boilers.
As a coolant in these boilers is used ordinary water or antifreeze with no special preparation on theelectrical conductivity. Depending on the model of an electric boiler, the kit may include the followingcontrols: the boiler thermostat, which regulates and maintains the temperature of the coolant. Safetythermostat that protects the boiler in an emergency (in case of overheating the coolant), level sensorand the coolant pressure sensor that turns off the boiler at least reduce the level of the coolant from thenorm. Freezing temperature sensor, which includes the boiler temperature falls below 5-7 ° C and apressure relief valve.For electric boilers can be connected to room thermostat or street, or as a programmer. The thermostatkeeps the temperature in a room. Street boiler thermostat sends information about the temperatureoutside the room. The programmer specifies the desired schedule for the boiler. Regulators, working,depending on the ambient temperature, provide the best comfort temperature control inside the roomwith changeable weather conditions.Electrode electric boilers.The boilers of the electrode type has a different operating principle: heating the coolant ions aremoving between the electrodes of the boiler. Thus, due to the ionization process fluid, is what makesthe form of positive and negative charged ions. Subsequently, the ions are attracted to one another,producing heat. These electrode boilers as coolant, mainly use water. For efficient water heater, youmust first prepare that it provides good ionization. But such treatment of water precludes its use incombined heating systems.Electrode Boiler is a vessel with electrodes placed in it. The action of the electrode boiler is similar towater heater. And the characteristic feature of these electric boiler is a very high efficiency - about 96-98% and an automatic setting for the given parameters of the carrier temperature. When a short circuit,or leak coolant temperature exceeds a given electrode boilers may themselves disconnected from thepower source.The heating system water from the electrode boiler is not instantly and consistently. When heated, thewater decreases its resistance, which allows better heat the entire system. Given the volume of yourheating system, you can configure the desired heating temperature of the coolant.Http://www.tms-nc.comhttP://www.ddaheatting.com
