Electric boiler for heating private houses, prices and types

Electric heating private house pot looks very modern

Electric boiler for heating private houses, especially

The operating principle of electric boilers based on the property of conductors emit thermal energy by passing electric current through them. In general electrocoppers simple device. In the heat exchanger circulating water through it, the electrical components are placed. They work from the home network 220, although there are powerful models, and working on the industrial network of 380 V. The heat exchanger is connected to the system home heating through the inlet and outlet fittings. The circulation of the heated water is naturally or with the help of a centrifugal pump. The entire process automation control system.

Modern electric heating boiler fits perfectly in the kitchen interior

Due to the absence of the flame and high heat, electric boilers have a number of advantages over other heating appliances:

• there is no need for a chimney and pipe;
• no noise;
• oxygen is not consumed in the room;
• small size;
• there is no risk of gas leakage;
• low price;
• ease of maintenance and management.

However, electric boilers for heating private house and not without drawbacks:

• the high cost and frequent power outages;
• sensitivity to voltage drops in the network.

If necessary electric boiler can be hidden in a recess

If necessary, heat a large area, you need a more powerful electric boiler that in addition to a large energy consumption entails also a need for more coordination with the supplier electricity. In some cases, the installation of a powerful boiler is not allowed due to limit the load on the power supply.

Useful advice! No need to chase the small boilers. Downsizing is always done at the expense of quality. It increases the load on the heating elements and they fail more quickly.

Electric boiler for heating private houses, prices and types

Depending on the type of heating elements, all boilers are divided into three main types.

Wall-mounted electric boiler does not take up much space and is easy to operate

Boilers with heating elements

The heating elements are used as a plate or tubular heating elements species. They are placed directly into the heat exchanger. In one arrangement, can be up to 8 elements 2 kW. All of them are connected in steps. It is governed by an automatic or manually. Some boilers are double-circuit, which allows not only to heat the coolant, but also water for household needs. The simplicity of the device, the ability to use any liquid (water, antifreeze or oil) as a coolant and low cost make this device the most popular among users. The formation of scale and large dimensions - the main disadvantages of these boilers. Prices for this type of boilers start at 50 USD and rise depending on the power, and the complexity of the electronics manufacturer to 1000 USD

The electrode device

Such electric boilers for heating private houses operate on a different principle. In the heat exchanger placed in the electrodes creates a potential difference of the alternating current. Since water is always dissolved salts, then it is a good electrolyte with a specific electrical resistance. Current passing through this medium, causing its heating. The advantages of this type of heaters include: small size, simple structure, safety and low cost (60 USD). Disadvantages: The water should contain a salt that increase its resistivity, the electrodes must be changed frequently due to their gradual dissolution.

Electric boilers are double-circuit. They are not only heated coolant, but the water in the domestic water supply

induction appliances

They are arranged much more complex than other boilers. The structure has an induction coil, which is a wire wound around the dielectric. Inside, it has a metal core. When the passage of electric current through the electromagnetic induction coil occurs, which creates a potential difference on the core by heating. This design allows several times to increase the efficiency of the entire device. Advantages of this device are: low energy consumption, unresponsiveness to coolant mind durability nonsusceptibility scaling. The disadvantage of such an electric boiler for heating private houses - the price. It is much higher than other types of heating devices and starts from 450 USD for the most basic equipment. The cost of powerful and complex devices can reach 3000 USD and more.

Useful advice!If possible, choose a boiler in good equipment, because some elements are essential. Better and cheaper to buy everything in the kit than to buy more expansion tank, valve, relay or filter.

Electric boiler can be easily integrated in the curtain furniture

Additional options for electric boilers

All existing types of electric boilers may have additional options. The most popular option is the possibility of manual power adjustment. It possess even the cheapest items. More expensive devices equipped with an automatic power control and switching off in case of overload. Of the additional features can still be listed as follows:

• Automatic draining when disconnected and the temperature is lowered to values ​​close to 0 degrees;
• remote sensor to automatically control operation of the boiler depending on the ambient temperature;
• protection from increasing or decreasing pressure in the system;
• built-in centrifugal pump;
• possibility to heat the domestic water supply system.

Depending on whether or not the other if additional options in electric boilers for heating private houses, their price can vary widely.

Sleek design and small size electric boilers is a welcome addition to their functionality

Calculation of power and connection of electric boilers

Before you buy a boiler, it is necessary to determine its capacity. After all, it will not allow the lack of sufficiently effective to heat a house, and the excess will result in unreasonable costs for electricity. There is a simple formula for calculating the capacity of boilers:

W cat = (S * Wstr.). 10,

wherein W cat. - the required capacity of the boiler, the S - area of ​​the premises, Wstr. - specific output device 10m². This rate is different for different climatic zones:

• for regions with temperate climates - 1.2 - 1.5 kW;
• Southern Zone - 0.7 - 0.9 kW;
• North zone - 1.5 - 2.0 kW.

Applying this formula to calculate the required power for the boiler room, area of ​​100 m² in a house situated in the middle lane: W cat. = (100 * 1.5): 10 = 15 kW.

Most electric boiler a bypass construction can be hidden in a cabinet-compartments in the hall

Useful advice!Those who do not like to trouble itself formulas and calculations, can simply divide the room space by 100. Then to the result you need to add 15 - 20%, depending on the climate.

How to connect an electric boiler

After the calculation of the required power is made, you can begin the process of connecting the equipment. Before you do this, you must obtain permission from the owner of the local power supply. The organization is obliged to issue the technical conditions, which will include the required parameters of the boiler. If the required power boiler greater ultimate load on the electrical network of the technical conditions, so it is impossible to connect the boiler. In this case it is necessary to use alternative sources of energy.

Wall-mounted electric boilers delight small size

The boiler requires a separate dedicated branch mains. Her protective relay set. The boiler is grounded and equipped voltage regulator. These actions will ensure safety and prevent damage to the unit due to power surges. Then the appliance is installed in its place. By appropriately connecting pipes connected feed pipe and return pipe. For models not equipped with an expansion tank and check valve, these elements also need to be provided.

Electric boiler for heating private houses, the price of which is placed in the heating installation cost estimate, and functional characteristics and quality satisfies the customer, when properly installed owners will enjoy a long uninterrupted work.
