Installation of an electric boiler in a private house is an instruction. Installation scheme of the electric boiler

One of the most modern ways of heating a private house is electricity. Thermal devices that consume electricity are characterized by noiselessness, environmental friendliness, high coefficient of efficiency and do not require constant attention from the person. Due to this many similar models are used as an additional or main source of heat.

Preparation of tools

The installation diagram of the electric boiler is attached to the manual. Having studied it, you can prepare everything you need, namely:

• Hardware;
• Pipes;
• drill;
• cable.

The drill is needed to make holes for the fasteners, while the hardware will allow the boiler to be fixed to the wall, this also applies to the mounting plate. When selecting a cable, you should determine the cross-section. In addition to pipes whose diameter should match the calculated data, couplings and flanges will be needed. Before the installation of the electric boiler is completed, it must be ensured that the material at the base of the wall will be able to withstand the weight of the equipment.

The location should be selected in such a way that there is free space left and on top of the unit. It will be required for access during repair work. It is important to ensure that the equipment does not have any distortions during installation, it can be checked using the building level. It is important to make sure that the material at the base of the wall is not combustible. For proper installation of the units, a mounting plate should be used. Pipelines that will be connected to the device must be calculated taking into account the characteristics of the pump.

Some nuances

It should be remembered that the low-power devices will operate from the 220 V network, whereas for the more powerful units it will be necessary to connect to a three-phase network. The calculation of the cable cross-section is made so that it can undergo the power of the device by passing a current of a certain value.

As soon as the device is connected, you can type water into the system, proceeding to check its operability. The methods of installing an electric boiler differ only in that wall models are attached to a vertical surface, while floor mounted on a special stand or pad.

Requirements for premises

Installation of the electric boiler is carried out in a technical room or a furnace room. In this case, none of the residents will accidentally be unable to disrupt the operation of the equipment. This is especially true of children. As an exception, TEN boilers of factory production act, they can be installed in the kitchen. Power cables should not be laid under heating and water pipes. If this can not be avoided, the cable should be protected from water, it can be done by enclosing it in a mounting metal or plastic box.

Installation of an electric boiler is accompanied by connection to the pipeline. In this case, it is necessary to exclude the possibility of loading the weight of other components of the body of the unit. Pipes should be well attached to the walls. It is important to observe the cross section of the conductors of the power cable, which must correspond to the current and power consumption. The equipment housing must be connected to the ground loop.

additional information

The boiler installation scheme will differ depending on the version of the unit used. For heating it is possible to use TEN induction or electronic installations. If a boiler is installed with a heater, the device must include a circulation pump, a heating element for hot water supply, as well as safety and automation equipment.

Thanks to this design, the installation will be simplified. But the induction or electrode heat generators are water heating elements, which presuppose the need for external tying.

Connecting the device to the heating system

Installation of the boiler is accompanied by its reliable fixation to the wall. TEN devices should be suspended at a level of 1.5 m from the floor surface or more. If we are talking about the other two types of equipment, then they can be set lower, as far as it will be convenient for making the strapping. The last two types of heat generators are installed vertically.

It is very easy to connect a TEN boiler with a circulation pump and the safety automatics to heating. The outlet pipes must be connected to the pipelines by means of a ball valve, which is supplied to the Americans for convenience. A diaphragm expansion tank is connected to the return line, a screen filter is installed on it, which is also called a mud valve. For its convenient cleaning before the mud collector, an additional ball valve must be installed. This will eliminate the need for emptying the entire system.

For reference

Installation of an electric boiler requires the presence of a pipe for emptying the pipeline. It must be embedded with a stop valve in the return pipeline. It is necessary to place it near the heat generator.

Features of connection to the system of electrode and induction boilers

If there is an induction or electrode electric boiler for heating a private house, then its installation will be somewhat more complicated. The fact is that such equipment is not supplemented by pumps, which must be used separately in the strapping. The peculiarity of the work of these devices is that they require the inclusion of a security group in the system. The composition includes a manometer, safety valve and automatic air vent. The valve is adjusted to the operating pressure, as indicated in the documentation accompanying the equipment.

Advice from a specialist

Quite often an electric boiler for heating a private house acts as a supplement to a solid fuel. This creates convenience in the operation of the equipment, which is especially true for the night time, when the firewood is burnt out, and there is nobody to make a new bookmark. In this case, the electric heater starts to work, maintaining the set temperature in the system until the morning.

The night tariff for electricity is lower than the daily tariff, so this approach can be considered expedient. If the boiler with the built-in pump is replaced with an induction or electrode heater, the pumping equipment will have to be purchased and installed separately. It will be located on the return highway.

Connecting to an electrical network

Installation of an electric boiler in a private house requires the connection to the power grid. Before carrying out these works, it is necessary to study the instruction. From it you can find out what is the minimum section of the power cable, what is the circuit and the connection points. In the scheme of switching the power circuit into the house network, it is necessary to provide for the presence of a protective shutdown device and automatic switches that must correspond to the ratings. These requirements are explained by the safety of the equipment. You can explain this rule also by the fact that people should be protected from electric shock.

When installing electrode and induction heat generators, in addition to switching on the mains, it is necessary to install a remote control unit and temperature sensors, between which wires are laid. These works are carried out in accordance with the scheme, which you can find in the technical passport of the equipment. If the installation of the electric boiler with their own hands is made, then before working with the electrical network, it is necessary to turn off the voltage.

Cost of works

If you are not sure that you can properly mount and connect the equipment, it is advisable to ask what the cost of installing an electric boiler. The price for such services averages 13,000 rubles for the installation of the device. This amount does not include the installation of the distribution manifold and boiler, for this you have to pay separately.

Conclusion

If you decide to purchase an electrode boiler, then the heating circuit must necessarily assume the presence of a manometer, air vent and a back-pressure relief valve. The open type system must be supplemented with a stop valve, which is installed on a section of the pipeline following the expansion tank.
