Electric hot water boiler: water heating, heating for a private house

Many manufacturers equip the boiler with a circular pump, expansion tank, temperature sensors. Boilers with such a set of elements are in the range above the average price level.

Electric hot water boiler for heating: pros and cons

To date, there are 3 types of electric hot water boilers - TEN, electrode and induction. Electrode and induction are not very popular due to the difficulties that can arise when installing or servicing instruments.

The principle of operation of the heater is simple - electricity is converted into heat, the carrier of which is water.

It is possible to single out single-boiler, which are designed for heating the room or two-circuit - in addition to heating, they provide the house with hot water in the faucet.

Electric hot water boiler for heating is easy to use, long-lasting and reliable.

Positive aspects:

• Economical use;
• Energy Efficiency - have a high efficiency of 99%;
• Environmentally friendly - no combustion products;
• Relatively low price.

Despite the advantages of hot water boilers, one can distinguish their disadvantages. All of them are connected with a power source - electricity. The price of electricity is constantly growing and the use of such boilers is more expensive than gas boilers. Owners of country houses with an electric boiler are constantly dependent on electricity supplies. If there is a rush of wires or the burning of wiring, the house will immediately begin to cool down. Therefore, it is advisable, in any case, to have a spare heating source - a cauldron on a recycled oil or a fireplace.

Electric hot water boilers for a private house: the principle of operation

Modern water heating boilers heat the room well, while consuming relatively little electricity.

To reduce electricity consumption, you can use a multi-tariff meter. The operation of the boiler in the evening and at night will reduce electricity costs by up to 30%.

When the electric boiler overheats, a fuse triggers that disconnects the entire

The basic set of the heating boiler includes an expansion tank, heating element, temperature control elements, pressure sensors and fuses.

The device works very simply - the coolant enters the expansion tank, in our case water. Due to electricity, water is heated and spreads through radiators and pipes. With the help of the control unit it is possible to regulate the operation of the device - to change the temperature of the water, to set the operating time of the boiler.

System shutdown occurs also with sudden voltage surges.

Boiler installation by own hands

Water heating boiler for heating a private house can be installed independently. For this type of boiler, no ventilation or chimney is required. It does not emit harmful substances and does not produce waste. Compact models do not require special insulation and can be installed in the kitchen. For more powerful models, it is better to allocate a special place for the boiler room type.

The only difficulty in the installation is the behavior of electric power. Since these boilers are powerful electrical appliances, a separate power supply line should be maintained by safety rules.

For boilers of low power up to 6 kW it will be sufficient to supply power from the 220 W system. For more powerful boilers from 12 kW, three-phase power supply from the 320 W network should be supplied.

Before installing the boiler, it is necessary to read the installation instructions that are in the package with the

. The calculation of the wire cross section will depend on whether it is copper or aluminum. Calculation formulas can easily be found on the Internet or call an electrician to calculate and lay the wiring.

A mandatory element for such a device will be the installation of an RCD.Considering that the boiler can leak, it is necessary to choose a place for laying the wire, so that in case of leakage there is no short circuit.

Be sure to follow all instructions, because incorrect connection of the boiler to the wiring may cause a short circuit or more serious damage.
