Electric boilers for heating private houses
Electric boiler - a heating device in which heat transfer agent heated to the desired temperature by means of special electrodes or tubular heating elements (heaters). Electric boilers are used in stand-alone heating systems private houses and industrial buildings. Coolant often serves specially prepared water. In some cases, low-freezing liquid, started on the basis of propylene or ethylene glycol.
Electric boilers can be used as the main element of the system, and in an emergency, in case of failure of the main unit - the solid or gas-fired boiler. For example, when the gas is turned off or if the run firewood or coal, the heating system will be able to continue normal operation due to electric boilers for heating included in it.
Heating electric boiler, regardless of manufacturer, consists of the following elements:
- a housing which has all the performance of the device units;
- a heat exchanger consisting of a tank with coolant and heating elements;
- control unit, control and security.
All boilers operate on the same principle. A heating element disposed in the tank, converts electrical energy into heat. Further, the coolant adjusted to the desired temperature, the tubes transferred to heating batteries.
Electric boilers for heating can be electric heaters, induction or electrode. Increasingly popular devices is a tubular electric heating elements. Also boilers divided by the operating voltage:
- Heating device - 220V;
- devices operating on the voltage in 380V and have a capacity of at least 12 kW;
- mixed type.
Distinguish boilers and method of installation - wall and floor.
E. boiler heating private houses as well as any device has its advantages and disadvantages. The benefits include:
- ease of installation;
- no need to supply fume collection channels;
- electric boiler has a higher ecological safety than gas or solid heating device;
- high efficiency - 95-98%;
- not required separate room for installation.
Among the deficiencies noted:
- the need for accurate the calculation of the cable cross-section;
- It is required to bring the boiler to a separate line from the switchboard;
- high cost of this type of energy source, in contrast, for example, from the gas.
We must take into account several factors, which are discussed below when choosing a heating equipment. If, however, the choice is made in favor of the electric boiler, you should also consider installing multitariff accounting unitWhich will save money.

Most private homes have an impressive area and the fact that Russian non-resort country where summer reigns all year round, this same area we have to somehow be heated in the winter. If the correct approach to this issue, it appears that Heating homes with electricity - the most economical way. This is what we'll talk in the publication.
types of electric boilers
As mentioned above, electric boilers for heating private houses are divided by type of heating elements into three categories - induction, electrode and TENovye. Let us consider each of these forms individually.
Electric boilers with heating elements - the device, merits and demerits
In such electric heating elements used boilers tubular or plate form, which are arranged directly in the heat exchanger. In single tank may contain up to 8 heaters with a capacity of 2 kW, which are connected in stages by means of automatic or manually. Some models of electric boilers TENovyh can have two circuits, which makes it possible not only to heat the coolant, but also water for household needs.
Often the decision to purchase of electric heaters electric boiler due to the simplicity of the internal structure of the heating device, the ability to use different types of coolant, and low cost, which ranges from 50 to 1000 $. Price depends on the capacity, equipment type and manufacturer.
Design and function of electrode boilers
The principle of operation of the electrode of the electric heating boiler differs from the operation of the heating device with heating elements. The electrodes, which are attached to the boiler in the heat exchanger creates a difference AC potential, which results in rapid heating of the heat carrier is specially prepared.
Electrode boilers are distinguished by:
- the number of loops (1 and 2);
- the number of phases (1-220V and 3-380V);
- power (2-50 kW);
- fastening method;
- principle coolant distribution (open and closed).
The advantages of electrode boilers are:
- Efficiency - 99%;
- low price compared with other types of boilers;
- small size and weight;
- fire safety and environmental friendliness;
- the possibility of placing virtually any room;
- automation of the processes of heating and resistance to surges;
- rapid heating of the coolant to the desired temperature;
- ease of installation.
This is only the basic advantages of the electrode of electric boilers for heating, in fact there are many more. Now list the disadvantages of this equipment, which is not so much:
- the need for a stable power supply, which is solved by additional automation of the boiler;
- It requires the use of only the prepared coolant;
- It must be mandatory grounding;
- single-loop circuit does not provide sufficient Water supply of private homes hot water;
- It required every 2-4 years to change the electrodes, due to wear.
Electric boilers Induction type
Induction heaters are much more difficult to other heating equipment. The design of this device is provided for heating the presence of the induction coil with a metal core. During the passage of current through the electromagnetic induction coil occurs, creating a potential difference across the core, whereby it is heated.
Such a design allows the boiler greatly increase the efficiency of the entire heating device. The system is very secure, since the induction coil is hermetically sealed in the housing, thereby avoiding contact with its winding coolant.
Deciding to buy an induction electric boiler should be aware of the following advantages of this equipment:
- high reliability (assuming continuous availability in the coolant system);
- small dimensions of the device;
- sufficiently high efficiency (efficiency depends upon competent heat exchanger structure and the whole system);
- the low inertia of the system, which makes it possible to minimize electrical losses;
- excluded the formation of scale;
- the use of different heat transfer fluids;
- autonomy of the boiler;
- installation and maintenance easy.
Induction type heating boiler is a fairly reliable device, and the only thing that can it fail, so it is the electronic control unit.
The only drawback of the induction electric boiler for heating private houses - the price, which ranges from 450 up to $ 3000 and above. This price discrepancy depends on the power and complexity of radiators. Currently, the heating equipment manufacturers offer two types of boilers - induction (the SAV) and vortex (VIN).
Induction boiler SAV type
Boilers of this type are used for independent and combined heating in hot water systems and as a standby heating device. In this kind of heating equipment permits remote adjust the temperature and automate the process of heating.
On inductor (primary winding) opdaetsya current frequency of 50 Hz, and a secondary winding is used as a closed pipe system, which is a heat exchanger through which the coolant passes. Induction current heats the liquid very quickly, which significantly increases the performance of SAV boilers, designed for 220 V and 380 V.
Such induction boilers with a capacity of 2.5 kW can produce heat 2100 kcal / h and heat small rooms up to 30 m². Price of equipment with automatic control unit is about 30 000 rubles.
Induction heaters such as WINE
In induction boilers vortex type (WIN) current flowing through the primary winding of the inverter is transformed to a high frequency. Consequently, increasing the overall strength of the electromagnetic field, which greatly contributes to the strength of eddy currents.
The housing and internal components of the boiler are made of special ferromagnetic alloy that becomes hot upon magnetization reversal. Due to this heat exchanger WINE boilers are not only pipe heating system in the SAV-type devices, but also directly with body parts, playing the role of the magnetic circuit.
Induction type boilers VIN 3 kW are able to produce up to 2500 kcal / h and heat the room area of about 30-40 m². The cost of heating equipment with a circulating pump, Valves and automatic control unit is 35-38 000.
Recommendations made! It is advisable to choose a boiler with as full equipped, as some components are essential. It is best to buy a full set, then in addition to not buy individually valves, filters, expansion tank or a safety relay. In addition, the full set as a result will be cheaper.

What you should know before choosing an electric heating boiler for private houses
By the choice of heating equipment should be taken very seriously, as you can buy the device who will be unable to provide your home with warmth and money, and a lot will be spent simply wasted. To find the electric boiler heating, fully meets your needs you need to know some of the required characteristics of the equipment.
Criteria for selection of an electric heating boiler represented by the following list:
- number of circuits;
- the presence of built-in additional equipment;
- power equipment;
- requirement for mains voltage and wiring;
- installation method.
- Contours. Electrical heating equipment may have one or two circuits. Combi boilers are mainly used in cases where you need to ensure that in addition to heating the house with hot water. So before you choose the heating boiler to a private home you need to decide - the device is only necessary to heat the premises or whether you want to use it as a water heater for household needs.
- Additional equipment. Depending on the manufacturer and the purposes of heating equipment developers boilers can be equipped with expansion tank, Circulating pump, system automation, security group, programmer, etc. Accordingly, the more options provided in the heating boiler, the higher its value. Often, however, the high price is justified by the fact that such content will supplement the heating system and protect it from various emergency situations and eliminate the problems with the heating of premises, as well as simplify the management and operation equipment.
- Wiring method. By way of central heating boilers can be wall-mounted or floor-standing. Floor installation usually used to heat private homes and larger premises, and equipment for wall mounting - in the flats high-rise buildings in an autonomous heating. Since no device is required to install the electric boiler fume collection channels, The installation of the equipment is quite simple and not time consuming.
- Power. If the power of the electric boiler is not more than 9 kW, then it can be powered from mains voltage of 220 V. However, the electric boiler for heating House of 100 square meters must be more powerful (the reason discussed below), and therefore need to be connected to a network with a voltage of 380 V.
In accordance with the capacity of the equipment and the necessary voltage is selected cable section and the machine type, which are usually specified in the data sheet of the heater.
The choice of the electric boiler power according to the area of private homes
Though at least it mentions capacity of the equipment, but it is perhaps one of the most important criteria that should guide the choice of the boiler. The fact is that lack of power will not allow to effectively heat a house, and its surplus will lead to unnecessary energy costs. There is a fairly simple way to calculate the power equipment such as electric boilers for home heating 50-60 square meters. To do this, the area of the room, which is supposed to be heated, divided by 100. To the obtained result is necessary to add about 15-20% (depending on climate zone).
You can calculate the power of the electric boiler and a fairly simple formula:
Wk = (S× Wud) / 10 Where:
- Wc - the power of the electric boiler;
- S - the area of the heated space;
- Wbeats- the specific power of 10 m² equipment.
The value of specific capacity may vary depending on climate zone:
- temperate climate - 1.2-1.5 kW;
- northern zone - 1.5-2.0 kW;
- south - 0.7-0.9 kW.
In accordance with this formula will try to calculate the power of the electric boiler for heating of houses 200 square meters located in the temperate zone: Wc = (200 × 1.5) / 10 = 30 kW.
In order to make more accurate calculations will have to use special tables and formulas that take into account the heat losses, the volume of space, as well as seasonal and regional factors. All these data can be found on the Internet at specialized sites.
A small video clip will help determine the choice of the electric boiler:
