Ash boiler installation. Heating systems for country and country houses

For autonomous heating of residential and industrial buildings, total area from 30 to 4000 m², heating systems are intended electric boilers Zota. Manufactured in the Russian Federation, they are fully adapted to domestic operating conditions and developed taking into account the wishes of consumers.

Model range of Zota electric boilers

The Zota line of boilers is represented by six modifications, two of which are not widely used, the remaining four are in stable demand. Among them are the following models:

The amount of electricity consumed is significantly reduced compared to analogues, due to design changes in the heating element and stepwise adjustment of the heating temperature.

How to install and connect correctly

Installation of the boiler is quite simple and does not require the installation of additional circulation or any other equipment. Models of the Economy series with a low power of 6-10 kW can be connected to a regular 220 V power supply. The connection diagram is attached to the operating instructions.

To install a more powerful installation, you will need to connect a separate voltage line of 380 V. Specifications boilers allow you to work despite voltage surges and reboots.

An external thermostat is connected to the control unit. All modifications are capable of connecting to the Internet. Using a special application for smartphones, it is not difficult to properly control the boiler from a distance. Timed activation is supported, as well as changing the heating intensity of rooms depending on the selected mode.

The boiler piping may require installing a filtration system for hot water supply and heating make-up.

Features of the operation of Zota electrical equipment

All models, without exception, can have a built-in GSM module. It is not included in the basic package and must be purchased separately. Additionally, installation and connection of the module can be ordered. The remote control panel can be installed in any room of the room.

Reviews show that Zota electric boilers have following features operation:

Boiler calculation by area- often excessive consumption of electricity occurs due to the fault of someone who incorrectly calculated the required productivity of the station. The power calculation should exceed the actual demand by 10-15%. A larger reserve leads to the fact that the boiler begins to overheat and often knocks out plugs in the room.
Service- it is impossible to connect the GSM module yourself. To connect to the voltage line, you will also need to invite a specialist. A company representative will also install an air temperature sensor. From time to time you will have to adjust the DHW water sensor.

Joint operation with a gas or heat boiler

The operating principle of Zota boilers allows them to be installed in conjunction with a solid fuel or gas boiler. Typically, in such a scheme, the electric boiler plays the role of an additional heating source, maintaining the required temperature of the coolant and replenishing the needs of the hot water supply.

In general, Zota electric boilers have a reputation as reliable and economical equipment. The main disadvantages are related to the complexity of connection remote control. There are minor flaws in the device that do not affect performance or ease of use.

Main advantages of the product

Zota electric boilers are in demand in Russia and abroad. Reliable and economical, they are adapted to different conditions their operation. The device is controlled using a special remote control. It can be carried out remotely. An important feature of these devices, which operate on the principle of electric water heaters, is their ability to perform self-diagnosis. This ensures absolute safety in using the equipment.

The main issue that will be discussed in this article is a typical diagram for connecting an electric heating boiler to a 220 and 380 Volt network. That is why the main bias will be directed only at the rules and sequence of connecting wires. As for the installation diagram of radiators, piping and other elements of the central heating system, we will provide it only in general form.

Installation options

So, first, let’s look at the options for connecting an electric boiler in a private house or apartment with our own hands:

If the power of the water heater does not exceed 3.5 kW, then it is usually powered from an outlet. In this case, the use of a single-phase 220V network is allowed.
In the event that the power varies between 3.5-7 kW, it is necessary to carry out electrical installation with your own hands directly from distribution box. This is due to the fact that the outlet may not withstand high current loads. As in the previous case, a 220-volt network is allowed for use.
Well, the last option that may come up is an electric boiler with a power of over 7 kW. In this case, it is necessary not only to run a separate cable from the distribution box, but also to use a more powerful 3-phase 380V network.

Electrical installation in a single-phase network

As we have already said, you can connect the water heater to a single-phase network through a plug or a separately powered cable. There is no point in even stopping at the first option, because... Anyone can insert a plug into a socket.

As for the second option, first you need to carry out (if the required diameter of the cores is not indicated in the product passport), and then bring the conductor to the place. Then everything is simple - we connect the phase, neutral and grounding to the corresponding terminals in the unit (markings are indicated on them). For your attention, a schematic diagram of connecting an electric boiler with a thermostat to the heating system:

Electrical installation in a three-phase network

The diagram for connecting an electric boiler to a three-phase network is more complex, but even a beginner can do it.

The three phases must be connected as follows:

Please pay attention to the following nuances:

Each water heater comes with a technical passport, which must indicate the manufacturer’s recommended wiring diagram for the electric boiler. Be guided only by this document in your case, because... The examples provided on the Internet may not always be suitable for your heating system.
Be sure to protect the boiler and... These devices will prevent overload of the unit, short circuit and current leakage in the electrical network.
The wiring must be grounded.

For your attention, a visual project of electric heating in a two-story dacha using a boiler:

This arrangement is one of the significant advantages of this model over others. An electric boiler allows you to place the control unit in a place convenient for you, while you are not tied to the pipes of the heating system where the heat exchanger is installed.
Power cable electrical wiring is laid exactly to the control unit.

The delivery set of the ZOTA - 12 boiler includes also a water temperature sensor, an air temperature sensor, a four-wire flexible cable for connecting the heat exchanger to the control unit, fasteners and instructions.

First of all, we connect the electronic control unit (ECU), having previously secured it in a convenient place on the wall. As you remember, we laid a five-core cable with a core cross-section of 4 sq. mm to the control unit; during installation, they should be inside the unit.

CONNECTING THE ELECTRIC BOILER CONTROL UNIT

We remove the insulation from the input power cable and proceed with the connection according to the following diagram:

IMPORTANT! Before connecting the electric boiler to electricity, be sure to turn off the power!

WORKING ZERO (blue-white wire) we connect to any of the two terminals marked “X2”, they are connected by a jumper and there is no difference in which of them the wire is placed.

PROTECTIVE ZERO or GROUND (Yellow-green wire) must be clamped with a screw, located to the right of the “X2” terminals, it is marked with a grounding sign.

Only then tighten this ring with a screw, thus obtaining a secure connection and reliable contact.

It remains to connect the phase wires to the terminals of the three-pole circuit breaker installed in the boiler.

The levers of this machine are independent; they are not united by a common jumper, which allows stepwise control of the power of the electric boiler.

It works as follows: each pole of the circuit breaker is connected to its own phase wire, which then goes to its own heating element.

The total power of the electric boiler is the sum of the powers of the heating elements located in the heat exchanger; if we turn off one of them with an automatic switch, the boiler’s performance drops by a third of the maximum.

The 12 kW ZOTA electric boiler we selected has three stages, each 4 kW respectively, the boiler can operate with a power of 4-8-12 kW, this is very convenient way adjustments.

When connecting an electric boiler to a three-phase electrical network, the order of phase rotation is not important, so you can connect the phase conductors to the boiler circuit breaker in any order. But I would advise sticking to the rule that the core colors always follow in alphabetical order:

1 - White conductor

2 - Brown conductor

3 - Black conductor

Now that electricity is supplied to the control unit, we connect it to the heating elements in the heat exchanger using the cable supplied.

I have already said that direct heating of water in this boiler model is carried out in a separate block, so now we will connect the electronic control unit with the unit heating elements- heat exchanger.

Please note that on one side the cable cores are crimped with standard lugs - this is for connecting to the terminals of the control unit, and on the other there are lugs in the form of a ring - this is for connecting to the contacts of heating elements.

The BLUE wire must be connected to terminal “X2” in the electronic unit control, where we previously connected the neutral power wire.

Remaining three wires, two BLACK and one BROWN, are connected alternately to the contacts of the electromechanical relay as shown in the image below:

The connection is made through a relay, and not directly through the terminals of a three-pole circuit breaker, in order to be able to automatically regulate the operation of the boiler. This is where the air and water temperature sensors included in the delivery kit come into operation.

On the control panel - the front side of the electronic control unit, there are regulators that set the air temperature - "AIR" and water temperature - "WATER", when the set values are reached, the boiler will automatically turn off, this operating algorithm is possible thanks to the relay.

The sensors also need to be connected to the ECU., for this there is a special terminal block marked “X1”.

Using the connection diagram connect the wires from the sensors to this terminal block as follows.

The blue wires of the sensors are combined and connected to the middle terminal. We place the red wire of the water temperature sensor in the left terminal, and the air temperature sensor in the right. The sensors themselves must be located outside the electronic unit.
This completes the connection inside the ECU; all that remains is to connect the plugs from the ECU board to the front panel and install it in place.

In the next article we will continue to connect the electric boiler to the network, next step there will be a connection of wires coming from the control unit to the contacts of the heating element in the heat exchanger. We’ll also talk about the method of automating the work used in this boiler model, water and air temperature sensors. Continuation of the article .

For heating a medium-sized building, the most in an efficient way heating will be a heating system based on an electrical appliance. In addition, such a system is the safest from an environmental point of view. And connecting an electric boiler to the heating system is an important and appropriate issue.

Electric heat generators have a high efficiency rate, which means they will provide the most optimal temperature in any type of room. Many modern electrical units are equipped with an adjustment system, which allows you to adjust their operating mode in the most optimal and convenient way.

Another advantage that electric heating devices have is the absence of parts that interact mechanically with each other. This reduces the risk of failure of these units several times.

If you compare a project such as a wiring diagram for an electric heating boiler with devices operating on other types of coolants, you can see some significant nuances.

As an example, let's take the connection of the Protherm SKAT electric heating boiler for heating. Only an employee from a specialized organization should connect such a boiler to electricity and the heating system. It is best to purchase the unit in a specialized store, as it will have all necessary documents and will be placed in original packaging. The packaging can only be opened in the presence of an employee from a specialized service. Together with the employee, you need to determine whether there are any mechanical damage or other defects on the surface of the unit.

Before installing an electric heating boiler, it is necessary to remove the plugs from the pipes and check that there is no dirt in the pipes and communications. To attach the device, you will need various gaskets and sealing materials.

Choosing a place to install a thermal electric generator

It is best if the installation of an electric heating boiler is carried out in non-residential premises. The kitchen would be an excellent place for these purposes. For the generator, it is necessary to choose a location that will be convenient both for installation and for its maintenance.

If you install the generator in accordance with the standards, then it is necessary that at least 5 cm of free space remain from its sides to the wall. There must be a free space of at least 70 cm in front of the device, at least 80 cm above the device, and at least 50 cm below it.

The heat generator should only be installed on a wall that is made of non-combustible material. To hang the device, you must use a special mounting strip. Such an element should be included in the basic package of the device. The plank must be attached to the wall using 4 dowels.

If a membrane-type expansion tank is installed in the device, then the heating system is designed for a volume of no more than 500 liters.

The heating connection diagram for an electric boiler implies that another membrane-type pressure compensator will need to be installed in a larger heating system.

Connection diagram of an electric boiler to the network

Before connecting an electric heating boiler, please note that the connection of the electric boiler to the network must be carried out using copper wiring. The cross-section of the wire must be no smaller than that specified in the document that came with the device. Device electrical connections external type must be made through special cable outlets. These pins should be located in the lower left corner. There should also be a brass grounding terminal with an M6 bolt.

When inserting an electric boiler into the heating system and installing grounding, you need to ensure that good and reliable contact is ensured between the metal body of the device and the brass bolt. Before connecting the bolt to the frame of the device, you need to thoroughly clean the connection area.

When installing an electric heating boiler into a heating system, you will need to use a room-type regulator that has a potential-free output.

If electric heating is planned to be organized for a building with large area, then when purchasing equipment you need to choose one that provides the possibility of installing a cascade. In order for the devices to operate normally in a cascade, the terminals of the control device must be connected to the unit that is being controlled. If the system installation is controlled using a room-type regulator, then the control contacts must be connected to the terminals of the control device.

The device must be inspected visually and make sure that it is in the correct position, the water pressure in the system is normal, and all communications are connected. All this is defined in the unit documentation.

After this, the installation diagram for an electric heating boiler involves the following steps:

It is necessary to check the serviceability of the pipeline fittings located in front of the unit. To do this, you need to switch it from the “closed” to “open” position, and vice versa.
All pipeline fittings of the electric heat generator are moved to the “closed” position. It is also necessary to move the pipeline fittings of the water supply and heating systems to this position.
On those pipelines that supply cold water to the unit, you need to open the shut-off valve. If you use an electric heating system, it is not recommended to use antifreeze liquids for it. This is because they have properties that can affect the operation of equipment in a negative way. Antifreeze fluids have a composition that can cause aging or rapid wear of rubber components.
It is necessary to install a sump filter or filter before entering the unit on the return pipeline. You can install both of these elements.
After the heating system is completely filled with water, you need to check how tight it is.

When the installation of an electric boiler with heating radiators is completed, you need to check how efficient the system sensors are. These include sensors such as: temperature controller, water pressure sensor, signal and control components of the unit, emergency temperature sensor.

During repairs of the heating unit or during unfavorable installation conditions, an electric heating unit can be connected using rubber hoses.

For the heating system it is necessary to use water with a minimum hardness level. Then the service life of the heating elements can be significantly extended.
