One of the most modern ways of heating a private house is electricity. Thermal devices that consume electricity are quiet, environmentally friendly, have a high efficiency and do not require constant human attention. Thanks to this, many of these 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 instructions. After studying 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 allow you to fix the boiler on the wall, this also applies to the mounting plate. When choosing a cable, the cross section should be determined. In addition to pipes, the diameter of which must correspond to the calculated data, couplings and flanges will be needed. Before the installation is doneelectric boiler, you should make sure that the material at the base of the wall will be able to support the weight of the equipment.
The place should be chosen in such a way that there is free space on the side and top of the unit. It will be needed for access during repair work. It is important to ensure that the equipment is not skewed during installation, this 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. A mounting plate must be used to properly mount the units. The piping 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 low power devices will operate on 220 V, while more powerful units will need a connection to a three-phase network. The calculation of the cable section is performed so that it can withstand the power of the device, passing a current of a certain amount.
As soon as the device is connected, water can be drawn into the system, starting to check its performance. The installation methods of the electric boiler differ only in that the wall models are attached to a vertical surface, while the floor models are installed on a special stand or platform.
Requirements for the premises
Installation of the electric boiler is carried out in a technical room or furnace. In this case, none of the residents can accidentally disrupt the operation of the equipment. It's inespecially for children. As an exception, there are heating elements of factory production, 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 possibility of loading by the weight of other elements of the unit body. The pipes must be well attached to the walls. It is important to observe the cross section of the power cable cores, which must correspond to the current strength and power consumption. The case of the equipment must be connected to the ground loop.
More information
The boiler installation scheme will differ depending on the type of unit used. For heating, you can use heating elements induction or electronic installations. If the boiler is installed with heating elements, then the device must include a circulation pump, a heating element for hot water supply, as well as security and automation equipment.
With this design, installation will be simplified. But induction or electrode heat generators are water heating elements that require external piping.
Connecting the device to the heating system
Installationthe boiler is accompanied by its reliable fixation to the wall. Heating elements should be hung 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 lower, as far as it will be convenient for strapping. The last two types of heat generators are installed vertically.
Connecting a heating element boiler with a circulation pump and safety automatics to heating is very simple. The outlet pipes must be connected to the pipelines using a ball valve, which is supplied with American women for convenience. A membrane expansion tank is connected to the return line, a strainer is installed on it, which is also called a sump. 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
Installing an electric boiler requires a pipe to empty the pipeline. It must be embedded with shut-off valves in the return pipeline. It must be placed near the heat generator.
Features of connecting to the system of electrode and induction boilers
If an induction or electrode electric boiler is available for heating a private house, then its installation will be somewhat more difficult. The fact is that such equipment is not supplemented by pumps, which must be involved in the piping separately. The peculiarity of these devices isthat they require the inclusion of a security group in the system. The composition includes a pressure gauge, a safety valve and an automatic air vent. The valve is adjusted to the set pressure, which is indicated in the documentation that came with the equipment.
Expert Tips
Quite often, an electric boiler for heating a private house acts as a supplement to a solid fuel one. This creates convenience in the operation of the equipment, which is especially true at night, when the firewood burns out, 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.
Night electricity tariff is lower than daytime one, so this approach can be considered appropriate. If you replace a heating element boiler with a built-in pump with an induction or electrode heater, then pumping equipment will have to be purchased and installed separately. It will be located on the return line.
Electrical connection
Installing an electric boiler in a private house involves 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 a residual current device and circuit breakers, which must correspond to the ratings. These requirements are explained by the safety of the equipment. This rule can also be explained by the fact that people must be protected from electric shock.
When installing electrode and induction heat generators, in addition to being connected 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 data sheet of the equipment. If you install the electric boiler with your own hands, then before working with the electrical network, you must turn off the voltage.
Cost of works
If you are not sure that you can properly mount and connect the equipment, it is recommended to ask what the cost of installing an electric boiler is. The average price for such services is 13,000 rubles for the installation of the device. This amount does not include the installation of a distribution manifold and a boiler, you will have to pay for this separately.
Conclusion
If you decide to purchase an electrode boiler, then the heating circuit must necessarily assume the presence of a pressure gauge, an air vent and a back-safety valve. The open type system must be supplemented with shut-off valves, which are installed on the pipeline section following the expansion tank.
