One of the most modern ways of heating a private house is electricity. Thermal devices that consume electricity are quiet, environmentally friendly, high efficiency and do not require constant attention from the person. Due to this, many such models are used as an additional or main source of heat.
Tool preparation
The installation diagram of the electric boiler is attached to the instructions. Having studied it, you can prepare everything you need, namely:
- hardware;
- pipes;
- drill;
- cable.
A drill will be needed to make holes for fasteners, while hardware will fix the boiler on the wall, this also applies to the mounting plate. When choosing a cable, you must determine the cross section. In addition to pipes whose diameter must correspond to the calculated data, couplings and flanges are needed. Before installing the electric boiler, make sure that the material at the base of the wall will be able to support the weight of the equipment.
The location should be selected so that free space is left on the side and on top of the unit. It will be needed for access during repair work. It is important to ensure that the equipment does not have distortions during installation, this can be checked using the building level. It is important to ensure that the material at the base of the wall is not combustible. For proper installation of the units, use the mounting plate. The 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 devices with low power will operate from a 220 V network, while for more powerful units, you will need to connect to a three-phase network. Calculation of the cable cross section is made so that it can undergo the power of the device, passing a current of a certain value.
As soon as the device is connected, you can draw water into the system, proceeding to check its operability. The methods of installing an electric boiler differ only in that the wall-mounted models are attached to a vertical surface, while the floor-mounted models are installed on a special stand or platform.
Room requirements
Installation of an electric boiler is carried out in a technical room or furnace. In this case, none of those living by chance will be able to disrupt the operation of the equipment. This is especially true for children. As an exception, TEN boilers are factory-made, they can be installed in the kitchen. Power cables should not be laid under heating and water pipes. If this cannot be avoided, then the cable should be protected from water, this can be done by enclosing it in a mounting metal or plastic box.
Installation of an electric boiler is accompanied by a connection to the pipeline. In this case, it is necessary to exclude the probability of loading by the weight of other elements of the unit body. 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 strength and power consumption. The equipment case must be connected to the ground loop.
additional information
The boiler installation scheme will differ depending on the type of unit used. For heating, TEN induction or electronic installations can be used. If a boiler with heating elements is being installed, then the device must have a circulation pump, a heating element for hot water supply, as well as safety and automation equipment.
Thanks to this design, installation will be simplified. But induction or electrode heat generators are water heating elements, suggesting the need for external strapping.
Connecting the device to the heating system
The 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 installed below, how convenient it will be to complete the strapping. The last two varieties of heat generators are installed vertically.
It is very simple to connect a heating boiler with a circulation pump and automatic safety to heating. The outlet pipes should be connected to the pipelines using a ball valve, which is supplied by Americans for convenience. A membrane expansion tank is connected to the return line, a strainer, which is also called a mud collector, is installed on it. For its convenient cleaning, an additional ball valve should be installed in front of the sump. This will eliminate the need to empty the entire system.
For reference
Installation of an electric boiler requires the presence of a pipe for emptying the pipeline. It must be inserted with stop valves into the return pipe. It must be located near the heat generator.
Features of connecting 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 involved in the strapping separately. A feature of the operation of these devices is that they require the inclusion of security groups in the system. It includes a pressure gauge, a safety valve and an automatic air vent. The valve is set to the set pressure, which is indicated in the documentation that came with the equipment.
Specialist advice
Quite often, an electric boiler for heating a private house acts as an addition to solid fuel. This creates a convenience in the operation of the equipment, which is especially true at night, when the wood burns through, and there is no one 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 electricity tariff is lower than the daily one, so this approach can be considered appropriate. If you replace a heating boiler with an integrated pump with an induction or electrode heater, then the pumping equipment will have to be purchased and installed separately. It will be located on the return line.
Mains connection
The installation of an electric boiler in a private house implies the need to connect to the mains. Before performing these works, you must study the instructions. From it you can find out what is the minimum cross-section of the power cable, what is the circuit and connection points. In the circuit for connecting the power circuit to the home network, it is necessary to provide for the presence of residual current circuit breakers and circuit breakers that must correspond to the ratings. These requirements are explained by the safety of equipment. This rule can also be explained by the fact that people should be protected from electric shock.
When installing electrode and induction heat generators, in addition to connecting to 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 an electric boiler with your own hands is done, then before working with the electric network, you must turn off the voltage.
Cost of work
If you are not sure that you can correctly mount and connect the equipment, it is recommended to ask what the cost of installing an electric boiler is. The price of such services averages 13,000 rubles for installation of the device. This amount does not include the installation of a distribution comb and boiler, for this you will have to pay separately.
Conclusion
If you decide to purchase an electrode boiler, then the heating circuit must necessarily assume the presence of a pressure gauge, air vent and back-pressure relief valve. The open type system must be supplemented with shutoff valves, which are installed on the segment of the pipeline following the expansion tank.
