How to connect an electric heating boiler to the electrical network. Electric boiler connection diagram: reliable protection and energy saving. How much power will be required

From the previous article about we know that there are three methods of heating the coolant. Accordingly, there are three types of boilers: heating element, induction and electrode. Today we will tell you about connecting an electric boiler to a heating system. Installation is carried out in two stages. The first stage is connecting to the heating system, and the second - to the electrical network. Considering that the units can operate on both 220 and 380 volts, the connection diagrams to the power source are slightly different. You need to know how to properly connect an electric heating boiler to a network with different power levels.

Connecting a heating element electric boiler

Please note that electric boilers do not require a chimney.

The heating element electric boiler is the most common for heating residential premises. This is because it is cheap and easy to maintain. Connecting an electric boiler to a heating system using heating elements begins with allocating space for its installation. In principle, it doesn’t matter where you put it, the main thing is that it’s convenient for you. Such units do not emit any gases, so they do not need a chimney, unlike a gas boiler. We talked about it in one of the previous articles.

Before connecting an electric boiler to the heating system, you need to determine the installation method and the number of circuits. There are hanging and floor-standing models that can work on several fronts at the same time. They heat the house and supply hot water. In each case, it is necessary to ensure that the unit is securely fastened. If the boiler is single-circuit, then it will have only two pipes. Water will flow into one from the return, and the heated coolant will come out of the second.

In dual-circuit models, there are also two more pipes, respectively. This is the input and output to the DHW circuit.

Before connecting the electric boiler to the heating system, you need to prepare seats on the circuit.

The heating element boiler is connected to the circuit using American wires. The connection must be such that when the American ones are untwisted, they remain on the pipes. For compaction you can use:

• flax with paste;
• fum tape;
• sealant.

At the junction of the American connection and the boiler, sealing materials are not used, since the design of the nut includes a rubber gasket. It is mandatory that the connection diagram of the electric boiler to the heating system includes a mud trap in front of the heater. Garbage must not get on the heating elements. If the design of the heating element boiler does not include a circulation pump, then it must be installed separately. The pump is placed in front of the boiler and after the expansion tank.

After the boiler is already connected to the entire heating system, it can be connected to the network. The boiler may already have sensors and serious “brains” installed that regulate the operation of the heater in accordance with user settings. Simpler devices do not have such frills, and if you want to expand the functionality of the boiler, you can assemble a separate electrical control unit. Control units can be designed for 220 and 380 volts, while there are units operating in both modes. Switch to the desired voltage manually.

The documents for the heater contain requirements for the thickness of the copper wire and recommendations on how to connect an electric heating boiler. In a single-phase network, a three-core cable is suitable for the unit, and in a three-phase network, a five-core cable:

• phase (one or three);
• zero;
• grounding

All electric boilers must be grounded - this is mandatory. Over time, you can expand the range of capabilities of the heater by adding new sensors and automation to the connection diagram of the electric heating boiler.

Connecting an electrode electric boiler

Please note that the pump is not positioned correctly.

The electrode boiler is the smallest representative in the niche of home heaters. Sure, there are different models with multiple electrodes, but the most common and well-known is the small single-electrode boiler. Such a unit can be installed on the circuit either in a vertical or horizontal position. In addition, the circuit for connecting an electric boiler to a heating system may consist of several heaters. They can be assembled into unique registers from boilers by serial or parallel connection.

The device does not have a built-in safety group, therefore the connection diagram for the electric heating boiler after it in the supply provides for:

• pressure gauge;
• air vent;
• emergency valve.

It is very important to make reliable grounding. The coolant is heated by electric waves; if the grounding falls off, someone who touches the pipes will receive an electric shock.

Devices up to seven kilowatts operate on 220 volts. More powerful units require a 380 volt network. Location of contacts on the electrode boiler:

• the electrode is a phase (one or three contacts, depending on the network 220 or 380 volts);
• the housing is zero and grounding.

This diagram shows how to connect an electrode boiler to a three-phase network.

Only phase wires are suitable for the electrode, and on the body there are two contacts with zero and ground. The pump is connected via the control unit. The minimum that should be included when connecting electric heating boilers is temperature sensors that regulate the operation of the heater. It is possible to assemble any control that suits your operating conditions. You need to install a pump in front of the electrode boiler, despite the fact that even without it the boiler is capable of raising water several meters. Connecting an electric ion-type heating boiler is impossible without salt preparation of the coolant.

Such units can only work if the water in the system has a certain level of salt. By adjusting the amount of salt in the water, you can reduce or increase the resistance of the coolant. The boiler passport contains a plate that indicates the necessary parameters for the heater to operate, such as current strength. It is inversely proportional to the amount of salt in the coolant. To control the quality and composition of the coolant, it is better to install a special filter for it.

Connecting an induction electric boiler

This is how an induction electric boiler is suspended. The fastening must be reliable, it is quite heavy.

The most common induction boiler has the shape of a pipe with a cross-section of about 20 cm and a length of almost a meter. This is a domestic product called “VIN”. The electric boiler is connected to the heating system through two pipes:

• straight;
• reverse flow.

Such a boiler does not have any additional circuits, only high-temperature heating circuits. The device is hung on a wall no lower than 80 cm, with nothing touching the body along the perimeter of 30 cm. Circulation without a pump is impossible. The supercharger is placed, as always, in front of the boiler. At the feed it is installed . Under the cover of the device there is access to the terminals. There can be two or four of them, depending on whether the unit is three-phase or single-phase. The device must be grounded.

An induction boiler can easily cope with large volumes of coolant, so its installation can be accompanied by the installation of a heat accumulator. These are tanks containing coolant with a volume of 200 liters or more. The average size of a heat accumulator is 300-500 liters. It collects heat and releases it when the boiler is turned off, thus increasing the time between turning on the heater.

Heating a private home with electricity is considered one of the most convenient heating methods. Heating units that consume electricity are environmentally friendly, quiet and highly efficient, and do not require constant attention from the homeowner. Thanks to this, many of them purchase electric heat generators as the main or additional source of heat. Our task is to tell you how to install an electric boiler and connect it to the utility networks of the house.

Many users are concerned about the room requirements for the heat generator. The existing regulatory framework does not make any requirements regarding where the unit should be located and whether a separate room is needed for it. However, there are Rules for the Construction of Electrical Installations (PUE), and they should be followed when installing this type of water heaters.

If you want to do everything right and ensure electrical safety in your home, then it is recommended to follow the following rules for installing the boiler:

The unit is best placed in a furnace or other technical room. Then no one living in the house (especially children) will be able to accidentally gain access to electrical power equipment. An exception is factory-made heating element boilers, which can be installed in the kitchen;

Do not lay power cables under water supply or heating pipes. In a situation where this cannot be avoided, all measures must be taken to protect the cable from water getting on it, for example, by enclosing it in special mounting boxes made of plastic or metal;

When connecting the boiler to the heating pipelines, do not allow the latter to load the body of the unit with their weight. Pipes must be securely fastened to the walls;

Observe the cross-section of the power cable cores corresponding to the power consumption and current strength. The body of the electric boiler must be connected to the ground loop.

It must be said that installation schemes for electric boilers vary depending on the type of unit used. At the moment, the following types of electrical installations can be used to heat a house:

• heating elements;
• electrode;
• induction

Boilers with traditional heating elements (heating elements) usually represent a real micro-boiler house enclosed in one housing. The device includes a circulation pump, automation and safety equipment, and in some models a heating element for domestic hot water. Thanks to this design, the installation of an electric boiler with heating elements is significantly simplified. In turn, electrode and induction heat generators are water heating elements that require external piping.

Connecting an electric boiler to the heating system

First you need to install the unit itself, securely attaching it to the wall. The heating element boiler is suspended at a level not lower than 1.5 m from the floor; the induction or electrode unit can be placed lower, as far as is convenient when piping. In this case, the last two types of heat generators are mounted in a vertical position.

Connecting a heating element boiler, equipped with a circulation pump and automatic safety system, to the heating system is quite simple. Below is an installation diagram according to which the piping must be performed:

The outlet pipes are connected to the pipelines through ball valves, equipped with American valves for convenience. A membrane expansion tank is connected to the return line, and a strainer - a mud filter - is installed on it. To make it convenient to clean it without emptying the entire system, an additional ball valve is placed in front of the dirt trap.

Note. The diagram does not show the location of the pipe for emptying the pipelines. Typically, this pipe, together with shut-off valves, cuts into the return pipeline near the heat generator.

The installation of electric boilers of induction and electrode type is somewhat more complicated. The reason is that these units are not equipped with pumps, which must be used separately in the piping. In addition, the peculiarity of the operation of these boilers requires the inclusion of a safety group in the diagram. It consists of a pressure gauge, an automatic air vent and a safety valve. The latter is adjusted to the response pressure, which is indicated in the technical documentation supplied with the electric boiler. The wiring diagram is shown in the figure:

Note. The figure shows the connection of an induction heat generator; turning on an electrode boiler will look identical.

Very often, homeowners install an electric boiler as an addition to a solid fuel boiler. This creates additional convenience in operating heating equipment, especially at night. When the firewood in the firebox burns out, and there is no one to make a new stack, the electric heater comes into operation, maintaining the temperature in the system until the morning. In addition, the nighttime electricity tariff is significantly lower than the daytime one. In this case, the joint strapping scheme looks like this:

Note. The diagram shows a heating element boiler in use with a built-in pump. If you need to install an electrode or pump, you will have to buy the pump and install it separately on the return line.

Electrical connection

Before starting this work, you should carefully study the operating instructions for the heat generator. It indicates the minimum cross-section of the power cable that must be maintained, points and connection diagrams. In the event that for some reason this information is missing, you can use the table to determine the cross-section of the cores:

Another important point that must be taken into account when connecting the heater to the electrical network with your own hands. In the circuit for connecting the boiler power circuit to the home network, it is necessary to provide a residual current device (RCD) and automatic circuit breakers of appropriate ratings. These are direct requirements of the PUE, the purpose of which is to protect equipment and people from electric shock. A typical connection diagram is shown in the figure:

In addition to connecting to the electrical network, when installing induction and electrode heat generators, you need to install a remote control unit and temperature sensors, and then lay wires between them. These works should be performed in accordance with the diagram in the technical data sheet of the heater.

Important! Do not forget to turn off the voltage in the home network before carrying out work!

Conclusion

In fact, installing an electric boiler in a private home is not very difficult. You need to be careful when tying the unit and monitor the quality of the connections. You also need to remember the Electrical Safety Rules and strictly follow the diagram that is presented in the product documentation.

It is impossible to achieve comfort in your home in winter without using a heating system. One of the main components in this case are electric boilers, which require proper installation in compliance with technical standards. The heating system will work efficiently if the electric boiler is connected rationally.

Features of the circuit when connecting to a heating system

If we compare this equipment with gas devices, they are easier to install, they have excellent performance characteristics, which has made such units the most common among consumers. But they have certain features that should be taken into account in order to achieve trouble-free operation of the device.

Another distinctive feature from gas boilers is the possibility of insertion into any place in the system. Thus, it can be connected to a circuit with forced or natural circulation of water. The device can be located at the lowest point of the system, which will guarantee maximum heating of the radiators. The discharge pipe should be located at the shortest distance from the battery level. The boiler circuit will provide for grounding on the heater. Its connection can be made to the switchboard. The zero phase of the electrical wiring should not be involved, because such actions are dangerous, the RCD identifies this and recognizes it as a short circuit in the equipment circuit.

The above-mentioned electric boiler connection diagram must be followed in parallel with the correct wiring. In addition to the equipment itself, you will need:

• thermal carrier;
• pipes;
• other components.

For reference

Tying is the connection of a device to a system where different components are used. If the piping is done correctly, the technician will be able to achieve a slight difference between the outgoing and incoming temperatures of the coolant. The boiler must be connected so that the water reaches the desired level in the small circuit. Once it enters the large circuit, the thermal energy will be transferred to the radiators.

Description of connection diagram

The connection diagram for an electric boiler requires compliance with a certain algorithm. To carry out the work you need to prepare:

• temperature sensors;
• shut-off and drain valves;
• pump for circulating coolant in the battery;
• tank;
• expansion filter;
• electric boiler.

You need to start work with markings, after which you can begin installation. The unit should be located as far as possible from the water pipe, this is required to eliminate the possibility of a short circuit due to a leak. The equipment can be mounted using bolts or dowels, and the surface is leveled not only horizontally, but also vertically. If we are talking about a floor-standing unit, then you will need a pallet.

The connection diagram for the electric boiler suggests the need to shut off the flow of water; this should be done before starting work. Connection can be made using couplings and adapters. The electrics must include a circuit breaker and an RCD of the required ratings. When connecting, it is necessary to ensure grounding, but cable channels will be required for laying the wiring. The devices are responsive to even minor voltage surges, which indicates the need to use a stabilizer.

What else is important to know about the connection diagram

The connection diagram for the electric boiler will differ depending on the circulation, which can be forced or natural. Thus, the circuit can be emergency, collector or on primary-secondary rings. It can also be direct or mixing. In the first case, the temperature can be changed using a burner, while the mixing one involves the use of an element of the same name, supplemented by a servo drive.

The connection diagram of an electric boiler to the heating system requires the installation of a boiler manifold, taking into account the return and supply lines. The system is connected to the boiler using a pipe of the required diameter; a three-way mixing valve is installed at the outlet, with which it will be possible to control the temperature. is installed on the return line, and in the next step you can install a unit that controls pressure and temperature.

Most often, double-circuit boilers are used to implement heating systems, which involve the passage of water through a small circuit. As soon as the coolant, which can be antifreeze or water, heats up, it flows in a large circle. Connecting an electric boiler to a heated floor is one of the types of piping. There are two more types, the first involves installing a hot coolant circuit (antifreeze or oil will pass through the electric boiler), and if we are talking about water, then it will flow into the tap. The third wiring diagram is a conventional connection to the electrical network.

When piping double-circuit equipment, its type is determined by the model that may have a mixer. Its installation is quite complicated, so it is impossible to carry out such work with your own hands; along with the correct connection to the electrical network, you will need to control the connection to the hot water supply.

Boiler cable connection diagram

Option c is relevant if the conditions under which aluminum-steel wires are connected to the house are met. Otherwise, the electric boiler connection cable is used. If we are talking about three-phase equipment, then additional wiring is required, and an aluminum steel wire is used, the cross-section of which is 1.8 mm 2. Specialized cables with a copper core are also used. The cable must be positioned perpendicular to the structure and lay a separate phase, which will be required for powerful equipment.

Cost of installation work

The cost of connecting an electric boiler may vary depending on its cost. Some companies indicate a certain percentage of the price, usually it ranges from 15 to 20%. However, if the equipment is too cheap, then a minimum threshold is set; it varies from 7,500 to 10,000 rubles.

Electric boilers for private use: reviews and cost

The most popular electric boilers on the domestic market today are the RusNit models, which are manufactured in Russia. If you are interested in foreign analogues, then you should pay attention to the companies Bosch, as well as Elbeva. If you are considering electric heating boilers for a private home, the price and reviews on them should interest you. Among others, the market presents the Protherm Skat 6KR model, for which you will have to pay 45,200 rubles. It is designed for heating small rooms, and also allows you to connect several in cascade. This, according to buyers, is an excellent opportunity to increase the output power. An additional advantage is the ability to connect an external boiler, which will be used in everyday life to prepare hot water. The power can be adjusted if desired, and the equipment itself will be reliably protected by a temporary delay from sudden voltage surges in the network. The boiler has two heating elements, each with a power of 3 kW. According to buyers, this equipment has a high efficiency, and the device does not require a chimney to operate.

Another model is “Evan S1-5”, the cost of which is 11,800 rubles, it is a device equipped with heating elements. The body is made of stainless steel, which consumers really like, because it extends the life of the equipment. The case contains: an on/off key, a temperature regulator and a heating indicator. All these functions allow you to operate the equipment with a high degree of comfort. When adjusting the temperature, the power remains unchanged, which is 5 kW. These prices, reviews of which can help you make the right choice, are compact in size and can be installed on the wall.

Conclusion

Before starting work, the technician must review the electrical diagram for connecting the electric boiler. Otherwise, mistakes cannot be avoided that can cause equipment failure.

A modern electric boiler is a good solution to the issue of heating, as well as hot water supply to your home. Having a number of advantages over other boilers, they are increasingly becoming the choice of Russian buyers when it comes to an autonomous heating system. However, the electric boiler still needs to be installed correctly, and although this is not the most difficult task, it nevertheless requires separate lighting.

Advantages of an electric boiler

How to install correctly

To make it easier for you to understand the main points related to the installation of an electric boiler, you should understand its essence. Namely, especially the design. It is such that electric boilers are mounted on the wall, while they are single-circuit and do not have a built-in boiler.

To provide your home with hot water, you need to purchase a water heater, which is usually instantaneous or capacitive. In the case when the equipment is built into the system and serves as a backup heat supplier, while the main boiler runs on diesel, gas or solid fuel, it becomes possible to connect it to the boiler.

The rules for installing an electric boiler are described in the documents that come with it.

All electric boilers have a number of requirements:

Installation must be carried out by a service center specialist who has permission to carry out electrical installation work;

Before hanging an electric boiler on the wall, make sure that it can support its weight without various types of deformation;

To facilitate access to the unit when carrying out repairs or maintenance, leave some free space on one or more sides.

Installation steps

Installation of an electric boiler is the simplest in comparison with the installation of other types of boilers. Since electricity will be involved in the heating process, there is no need to store and supply gas or liquid and solid fuel, or create a chimney. Installation of an electric boiler can be divided into several stages:

The fastenings necessary for the boiler are installed on the wall, the brackets are leveled and care is taken to ensure that there are no distortions;

It is necessary to create grounding;

The boiler is connected to the heating system. The circulation pump and expansion tank, if not built into the boiler design, must be installed separately;

Start-up and commissioning of equipment is underway. The system is checked for leaks in all areas, after which excess air is removed and the operation of the unit is checked in all modes.

Before installing the equipment, you need to check that all tools are at hand. These include:

Instructions included with the unit;

Flanges and couplings;

Pipes of suitable dimensions;

A cable having a certain cross-section;

Hardware with which the boiler is attached to the wall;

Mounting plate;

A diagram showing the correct installation of an electric boiler.

Installation process in the right order (video)

So, having checked the wall to which the boiler will be attached, and making sure that it can bear the required load, we leave a little free space for access to the boiler (usually it is indicated in the instructions) and install the unit, checking the evenness of its location using a level.

The wall on which the boiler is mounted must be made of non-combustible materials.

The mounting plate will be useful to you for proper installation of the boiler. Pipelines should be selected based on which pump is installed in the system.

Basically, installing an electric boiler is not difficult, however, as in any business, there are some interesting aspects. Thus, boilers with low power always work well in a regular network with a voltage of 220V. Another thing is that if the model is powerful enough, it needs to be connected to a three-phase network. This is why it is so important to correctly calculate the cable cross-section. A properly selected cable can withstand the power of the unit and pass the required current without failure.

After the boiler is installed, the heating system and water supply system pipes are connected to it. This is where couplings and flanges come in handy.

The next step is to connect to the mains. RCDs and circuit breakers with the required ratings are pre-installed, and grounding work is carried out. The cable is equipped with a switch, the distance between the contacts of which is 3 mm. As soon as the device is connected to the system, you can draw water, start the unit and check it in action.

There is almost no difference between installing wall-mounted and floor-standing boilers, except that floor-standing boilers are installed on a special stand.

Features of boiler installation

If you feel strong enough to install an electric boiler yourself, take advice from knowledgeable experts. It is best if the electric heating source is used as a backup - this will allow the resulting heat to be spent more efficiently in the room.

A non-return safety valve, a pressure gauge and an air vent are the elements that you will become familiar with if you install an electrode-type boiler.

If you have an open heating system, then a shut-off valve is installed on the section of the pipeline that comes from the expansion tank.

For grounding, a copper wire with a four-millimeter cross-section is used when connecting the conductor to the neutral terminal of the equipment. It can be found on the boiler body in its lower part.

It is best if the boiler is built into a new system rather than into an existing circuit. Otherwise, the circuit must be rinsed thoroughly using the products intended for this purpose.

After installing the electric boiler, make sure that all rules for safe operation are followed and that the boiler itself operates normally in all modes. In this case, the installation can be considered successful.

In this article we will not consider the process of connecting an electric boiler to radiators, cold water, filters and other elements of the heating system. Readers will be provided with a part directly related to electrical installation work: connecting an electric heating boiler to the electrical network, grounding and installing protective devices. Therefore, we will not waste your time and get down to business.

Advantages and scope of electric boilers

Most often, electric boilers are used in dachas and private homes. This is due to the fact that this equipment has a low cost and at the same time you can install it yourself, without calling a specialist.

Among the main advantages of electric boilers are:

• the equipment is safe (the design does not include open flames or the presence of flammable fuel sources);
• water heaters can be switched off for up to six months, without harm to their performance (relevant for dachas and country houses that are rarely visited);
• the dimensions are relatively small, so it can be placed in any room;
• Today there is a huge variety of electric boilers, varying in power, installation method and principle of operation;
• When water is heated, soot does not appear, which is dangerous for both humans and the environment.

Safety regulations

Before we move on to the main part of heating installation, I would like to pay attention to the safety of electrical installation work.

Firstly, the connection of the electric heating boiler must be carried out when the electricity is turned off.

Secondly, it must be installed at a certain distance from other objects, namely:

• there must be at least 5 cm of free space between the body and the walls;
• the front panel must be accessible for maintenance; 70 cm of free space is enough;
• the distance to the ceiling is no less than 80 cm;
• the distance to the floor is at least 50 cm (if the electric boiler is of a hanging type);
• the distance to the nearest pipes is at least 50 cm.

Third, the network must be three-phase (380 V) to reduce the current load on the electrical wiring. When using a single-phase network to connect a powerful boiler, the wiring may not withstand it, resulting in spontaneous combustion and.

Fourth, everything must be sealed and protected from water. Water ingress onto the contacts can occur if the pipeline is damaged (for example, the coupling connected to the unit bursts) and if condensation drains from the ceiling (in an unheated room). It is also recommended to protect the cable with corrugation or a cable duct made of self-extinguishing material. If the wires catch fire, these products will prevent the flame from spreading.

Electrical installation diagrams

So, for your attention there are several typical do-it-yourself diagrams for connecting an electric boiler in a house:

As you can see, the projects are quite simple and consist of the water heater itself, a transport line (pipes), a circulation pump and radiators. Your task is to correctly connect all the elements together, and then turn on the power supply.

Main process

Installing the unit

First you need to install an electric boiler indoors. As we have already said, the unit can be floor-mounted or wall-mounted. In the first case, the kit includes a special stand, on which the “landing” is performed.

In order to hang the boiler on the wall, you need to prepare anchors with dowels and a drill with a suitable drill bit. First, mark the wall using a tape measure and a marker. The holes must be placed perfectly level in a horizontal plane. Next, we drill out the marked places, drive dowels into them and screw in the anchors. After the anchor is firmly seated inside the wall, you can hang the electric boiler.

We draw your attention to the fact that the installation of the electric boiler must be carried out perfectly level in both the horizontal and vertical planes. Any misalignment can affect the performance and service life of the equipment.

We connect the electrical wiring

Since an electric water heater has more power, it is necessary to connect it not from an outlet, but directly from the mains. To do this, a separate line must be drawn from the distribution box in the room, going to the boiler connection point. It is better to use hidden cable routing, because... in this case, the line will be protected from mechanical damage and the appearance of the room will not deteriorate.

It should be noted that to power the boiler it is necessary to use a large cross-section cable that can withstand fairly high current loads. We talked about how to implement it correctly in the corresponding article, which we strongly recommend that you read.

So we draw your attention to the fact that small-power water heaters (up to 7 kW) can be connected to a single-phase network, which is often found in Khrushchev-era buildings and old-style apartments. Well, the last nuance at this stage that you should know about is that electric boilers up to 3.5 kW can operate from an outlet, and not from a separate line from the distribution box. Low-power boilers are ideal for connection in an apartment, because in this case the electrical wiring is usually single-phase and making new cable routing is not always a practical solution.

We install protective equipment

When all the input wires are connected to the electric boiler, it will be necessary to additionally protect it by installing it in the main panel. The purpose of the first device is to protect equipment from short circuits and wiring overloads. Connecting an electric boiler through an RCD will protect you from.

It is also recommended because even small surges can damage the unit. I don’t think it’s worth talking about the need to ground an electric boiler. The main requirement is that the ground wire runs directly from the bus to the equipment frame.

We are launching

When all wiring elements are connected, it is necessary to check all connection points. There should be no exposed contacts, as well as damaged insulation.

It is also necessary to check all couplings, taps and pipe joints. Only after a high-quality inspection of the heating system can you proceed to its start-up. First, we open the valves connected to the equipment, and then turn on the electric boiler.

Pay attention to the functionality of the temperature and pressure sensors. The nominal values ​​are indicated in the instructions included in the kit. In case of obvious deviations, it is better to call a specialist.

We also provide for your attention a clear example of installation work:

What can you save on?

Electric heating is quite expensive compared to gas heating. To make it economical, it is recommended to consider the following tips:

1. Buy electricity and turn on the heating at night. During the day, as a rule, everyone is at work and there is no need for the boiler to operate. It is better to properly heat the room at night, because at this time the price for 1 kW of electricity will be much lower.
2. Use automation that will allow you to turn on the heating at a certain time or only when the temperature drops by a set value. In this case, the unit will operate only when absolutely necessary.
3. The highest heating of radiators is achieved by placing the boiler at the lowest point of the heating system.
4. Add a modern solution to your heating system - it will allow you to more efficiently use the heat consumed throughout the room.
5. We return to the use of two-tariff meters. Another option for their rational use for heating is to buy heat accumulators. These containers of water can heat the room throughout the day, while the liquid will heat up at night (when electricity will cost much less).
