Specifics of installation of electric boilers
Despite the fact that installing the structure is not particularly difficult, and it can be done in any desired place, each device still hides its own peculiarities. And these are the ones that need to be known and taken into account.
- As a rule, manufacturers produce a unit without a built-in boiler. And the execution is carried out in a wall version.
- To supply the room with hot water, you will need an electric heater.
- First you need to worry about the reliability and stability of the wall to which the boiler will be attached in the future.
- Ensuring accessibility is also considered important. In which case, qualified technicians must have direct access to the device.
Technical requirements for installing electric heating boilers
This aspect also has its own nuances, which are strongly recommended to be adhered to.
- Before installation, you should make a concrete screed with a thickness of at least 70 millimeters and attach the structure itself to the bottom of them. This is due to the high weight indicator.
- In order to maximize the operating time, you need to connect a balancing valve, which will regulate the volume of coolant and select the most economical mode option.
- A very important element is the chimney, which requires special attention. The part that goes through the attic must be insulated. And inside there is a stainless steel liner. In addition, it is advisable to make a condensate collection area.
- The expansion tank and boiler must be connected by safety lines.
ATTENTION! It is prohibited to install various valves and taps on them.
- To prevent back pressure in the water supply pipe, it is necessary to build protection.

For wall and floor types, the beginning of the instructions will be slightly different. Let's deal with the first of them first. To install the unit, it is recommended to perform the following steps in the same order:
- First you need to make markings. Stick to the fact that the boiler should be located as far as possible from the water supply system.
- Drill the marked holes with a drill.
- Next you need to attach the profile and mounting strip. Take the dowels and connect the device itself to them.
IMPORTANT! the device must fit snugly against the wall, which, in turn, must easily support it.
Floor view:
- To begin, the metal stand must be screwed to the floor.
- Then bring out an individual line for supplying energy and ground it, having previously made a center for this: connecting the pins, deepened into the ground, with the fittings.
- It is necessary to select a certain cross-section and route its cable to the boiler.
- A residual current device must be installed next to the structure and sensors for temperature regulation and a timer must be installed separately.
- If there is no expansion tank and electric pump, they must be installed.
- Fasten all three elements of the system: tank, pump and boiler. For this you will need metal pipes.
- And, therefore, you can begin installation: shutting off the water and connecting the unit to the pipeline, and then to the water supply.
- Now you can check the performance and eliminate the air that is inside.

In general, the installation principle is practically no different from the previous scheme.
The main thing is just to correctly connect all the elements to each other and turn on the power.
Installing an electric boiler: step-by-step guide
Before starting the process, you need to prepare all the necessary tools. These include:
- drill;
- coupling;
- pipes;
- cables;
- mounting plate;
- instructions and hardware.
Electric boiler installation
As already mentioned above, before mounting you should make sure that the wall is ready to withstand further load. Therefore, you should take this issue seriously, thereby choosing a reliable place. Also, the installation must be without various distortions. To prevent this, it is recommended to use a building level.As for the material from which the wall should be made, it is non-combustible. For this stage, a mounting plate is used. A significant requirement is the shut-off valves in the section that is located immediately after the expansion tank. It is best to install the device itself in a new system. If there is already a circuit, then a thorough flushing is necessary. To do this, you should use special tools.
Wiring a wall-mounted electric boiler
The presented aspect includes the following steps that should be followed:
- Circulation pump. This component can provide you with convenience when moving coolant. This happens through the heating circuit. It is thanks to this element that all heating elements of the system are supplied with heat.
- Expansion tank. It is needed in order to accept everything unnecessary from the coolant in case of excessive overheating. Otherwise, if it is not installed, there is a high probability of a sudden pipe rupture, which will result in major damage.
- Safety valve. The device has a special purpose in emergency situations. The excess mass emanating from the coolant is released into the sewer center at lightning speed.
- Automatic air exhaust. If the system is not equipped with such a structure, then circulation will occur with difficulty and will be accompanied by characteristic noises and sounds. Since air removal from the circuit will not be ensured independently.
- Pressure gauge. Using it, you can analyze and regulate the pressure level that is in the entire heating system. The indicator should be approximately 4 bar.
Boiler connection
To begin with, you should remember that devices with a power of no more than 3.5 kW are connected to the outlet. But if the device has parameters less than 7 kW, then it is worth purchasing a distribution panel. In a three-phase system with boilers of more than eight kW, connection is only available with an electrical network of 380 Watt. In addition, it is possible to purchase a separate machine. The cable must be equipped with a switch, the distance between which must be three millimeters. After this, you can make the connection and check the functionality of all the fittings.
REFERENCE! Be sure to check for serviceability. It is advisable to switch the entire structure to the “closed” mode. Before entering the unit, you should install a filter on the back side. The final step is to fill the boiler and check for leaks.
What is the best way to wire an electric boiler?
In recent years, it has become increasingly popular among consumers. polypropylene. This is due to its high availability and budget option. The advantages also include:
- long service life;
- resistance to stress in aggressive situations;
- absence of plaque on the inner sides of the walls.
In addition to the above, such material is capable of creating a contour for a wide variety of designs. There are two options for the strapping itself: natural and with forced movement. The first type is a simple structure without a pump. It is most often used to heat rooms with a small area. This method is perfect for a boiler room, since it won’t be difficult to do it yourself.Those people who are homeowners should think about the second option, as this one allows for self-regulation. However, a reliable source of energy and time for periodic balancing will be required. And if damage occurs, you will have to call a special team, since only they can handle the troubleshooting.
Safety rules when connecting an electric boiler in the house
Of course, it’s not enough that you need to know in detail all stages of the process. You need to remember all the requirements that can protect you and those around you from the undesirable consequences of negligence.
- Turning off the power before starting all activities is mandatory.
- Maintaining a certain distance is strongly recommended. This moment includes: a gap from the body to the walls of at least five centimeters, to the ceiling of more than 80 cm, to the floor of at least 50 cm and the same value to the surrounding pipes.
- The network must be three-phase. Thanks to this, the load on the electrical wiring will be reduced. In the case of using one phase, the component may not withstand and catch fire.
- Don't forget about sealing. And also about protection from water. It is advisable to know in advance that this can happen due to condensation or damage to the pipeline. Therefore, it is advisable to purchase a special corrugation for the cable, which will guarantee safety from both breakdowns and possible fires.
Taking into account the tips and guides presented, doing your own installation will not be difficult.
