Evan electric boiler connection diagram

This topic will cover:

electrical diagrams of boilers;
possible causes of boiler breakdowns and ways to eliminate them,

options for connecting electric boilers will also be considered for:

two-wire single-phase network;
four-wire three-phase network with a neutral wire.

For the two connection methods, you need to know that when connecting any electrical equipment, and we are talking about electric boilers that are equated to this category, the connection is made with grounding.

In this topic, the casings of electric boilers are subject to grounding.

Why does this need to be taken into account? - Then, in the event of a breakdown of the conductor phase insulation on the metal parts of the body and a person accidentally touches the body of the electric boiler, the current potential in the human body decreases.

Replacing the heating element

Replacing the heating element and other elements, as well as diagnostics to determine the cause of the malfunction, is carried out in a passive way when the electrical equipment is disconnected from the external alternating voltage source.

This issue cannot be resolved on your own if you are not an electrician and such work is carried out accordingly if you have knowledge of the regulatory documents of the electrical safety approval group.

So what is the need for these details? — You may ask, if in this or that case there is a malfunction, you can call the electrician directly.

Well, let's put it this way - knowledge of electrical and electrical engineering will not be superfluous for you.

Connecting an electric boiler

Let's consider connecting the EVAN S1-30 electric boiler to a four-wire, three-phase network with a neutral wire.

The fifth PE conductor in the diagram in Fig. 1 is grounding and is connected to the body of the EVAN S1-30 electric boiler. Reading the connection diagram:

The electric boiler is equipped with so-called buses; a network cable with a plug is connected to buses N, A, B, C. From the buses, three phases A, B, C have branching. One branch of phases A, B, C is connected to the first contacts of the heating elements of two blocks.

The second branch from the same four buses is connected through a starter to the second contacts of the heating elements of two blocks.

Here it should be taken into account that for each individual block with heating elements, each individual heating element is connected to phase wires as follows:

Phase A and neutral wire N from the busbars are connected to the control panel. In its combination, the control panel is connected to a voltage of 220 V, the conductors from the control panel are connected:

with pump;
with air temperature sensor;
with thermostat sensor;
with self-resetting thermal switch.

The control panel consists of electronic elements that are not indicated in the diagram.

For electronic elements, diagnostics are outlined in this blog.

After carrying out repairs to replace one or another electrical part:

block with heating elements;
self-resetting thermal switch

and other parts included in the electrical circuit, it is necessary, before connecting the electric boiler to an external source of alternating voltage, to check the electrical circuit of the boiler for resistance. Diagnostics of the resistance in the electrical circuit of this circuit is carried out either with an ohmmeter or a multimeter with the appropriate function.

If, as a result of measuring resistance, the device indicates a zero value, in this example you should reconsider the connections you have made. A zero resistance number indicates a short circuit in the electrical circuit.

Consider the following electrical circuit for two types of boilers EPO-7.5 and EPO-9.45. The electrical circuit shown in Fig. 2 is identical and the difference here is only in the power of electric boilers. Let's follow the connection diagram:

These types of electric boilers are connected to a two-wire, single-phase network. The PE grounding wire is connected to the heating element block and to the body of the electric boiler. The phase wire from the phase bus in this circuit has a branching, one wire with phase potential goes to the control panel and is connected from the control panel to the first contacts of the heating elements,

Commissioning works include

Connecting the boiler to the electrical network;

Filling the system with coolant;

Removing air from the heating system;

Bringing the pressure to normal in accordance with the requirements of this operating manual (when using an expanzomat);

Trial run;

Adjustment of the system and shut-off valves;

Before installing the boiler, check the correctness and quality of installation of the heating system with natural circulation. The pipes of the heating system must be located so as to facilitate the natural circulation of the coolant. In this case, the maximum coolant level should not exceed 30 meters to the boiler level (working pressure in the boiler is not higher than 0.3 MPa). If it is impossible or undesirable to achieve natural circulation of the coolant in the heating system, it is necessary to use a circulation pump. The heating system must have an expansion tank communicating with the atmosphere. When using a membrane-type expansion tank, a safety valve must be installed at the outlet of the boiler in front of the ball valve, designed for a pressure of no more than 0.4 MPa. Since when the safety valve is activated, coolant or steam may be released through its drain hole, it is necessary to connect a drain to it sewer system. Ball valves are installed at the inlet and outlet of the boiler, which are used during dismantling, repair and maintenance of the device.

Installation of shut-off valves on the pipeline connecting the expansion tank to the heating system is prohibited!

The pressure testing of the heating system with the boiler after installation is no more than 0.4 MPa. The boiler must be mounted in a vertical position. The control panel is mounted vertically at a height of 1.4-1.7 m from the floor on walls and structures in well-lit rooms.

Technical features of boilers

The product range of boilers is represented by the following series:

The “Standard” series is represented by the “Economy” and “Standard” models. All boilers of the standard category are characterized by the ability to smoothly adjust the coolant temperature and are equipped with an input for connecting a circulation pump. The design of these boilers is extremely simple and consists of a metal cylinder, in the lower part of which there is a heating element, and in the upper part there is a temperature regulator sensor.

The line of this series is rich in models of varying power - from 2.5 kW to 30 kW. For heating large areas, the additional installation of a circulation pump and an expansion tank is required. Typically used as electric boilers for home and small offices.

Devices in this category differ in their equipment - for example, depending on the power, the models contain a certain number of heating elements and connectors for connecting room temperature sensors.

Among private property owners, devices of this series are most in demand.

Electric boilers "Evan" have different technical characteristics in this series, depending on the presence or absence of a three-stage switch, a built-in circulation pump, and an electronic control unit. Accordingly, more expensive models have all three mechanisms, while economical models only have a three-stage power switch. The boiler power range is from 3.5 kW to 30 kW. They are used as electric boilers for homes, offices, and warehouses.

Boilers of this series have very high power characteristics - thus, the model range is represented by units with heating output from 36 kW to 480 kW. The boilers have (not in all models) four-stage power regulation, protection against short circuits, inappropriate pressure, overheating and overload.

Review of model range and prices

EVAN electric boilers are divided into the following classes:

"standard-economy";
"standard";
"comfort";
"luxury";
"VIP";
"professional".

All boilers use tubular electric heaters made of Backer stainless steel (Czech Republic), which are characterized by increased reliability and long service life. In most models, both water and non-freezing liquid intended for heating systems can be used as a coolant. The coolant temperature is adjustable from 30 to 85 degrees.

When choosing heating equipment, two main criteria can be distinguished - power and the type of fuel on which the device will operate.

Electric boilers "standard - economy" class

Electric heaters of the “standard-economy” class are the most budget model in the range of EVAN devices; they are used both in homes and in dachas. A 20 percent reduction in the price of equipment compared to the “standard” class is due to the absence of a housing that combines the boiler and control panel.

Models of this class are called EPO and include models of 12 standard sizes, designated as follows: electric boiler EPO 2.5, where the number indicates the power of the heating equipment in kW.

Specifications:

The power of electric boilers of this class ranges from 2.5 to 30 kW with a high efficiency of 99%.
The operating voltage of the boiler used is from 220 V or 380 volts and depends on the brand of the boiler.
Depending on the brand, heating equipment uses one or three heating elements and uses one-stage or three-stage remote control panels. EPO 2.5 uses a built-in remote control.
To ensure safety when heating water or liquid to a set temperature, the thermostat turns off the boiler, and when the temperature drops below the set temperature, it switches to heating mode.
As protection against overheating, a self-resetting emergency sensor is used, which is triggered when the water temperature ranges from 89 -95 degrees.
The system includes a connector for connecting an air temperature control sensor or a remote control module (except EPO-2.5).

During installation, a floor-mounted installation option is used. The dimensions of the heating equipment used come in two sizes: 505 x 200 x 160 mm and 565 x 270 x 220 mm and depend on the brand of electric heaters. Net weight varies from 6.5 to 13 kg. Estimated prices from 7800 rub. up to 28800 rub. The warranty on all boilers is 18 months.

Evan boilers: pros and cons

Among the disadvantages of electric heating boilers for the Evan home are the dependence on electricity and its high consumption. However, the listed disadvantages are more or less characteristic of most electric heaters. Regarding Evan boilers specifically, many owners complain about the noisy operation of the devices, unreliable heating elements, frequent relay breakdowns and failure of the boiler automation.

Therefore, when choosing a boiler, it is better to consult with a company specialist, because the causes of breakdowns are often caused by operating conditions, instability of the supplied electricity, incorrectly executed connection diagram of the electric heating boiler and other reasons not related to manufacturing defects.

Speaking about the advantages of these Russian boilers, they usually highlight their low cost, ease of installation, a huge selection of models and ease of operation. In addition, the devices have all the advantages of electric boilers as such.

In this series, they note the absence of the need to prepare fuel and install a chimney (as is required in the case of gas and solid fuel boilers), high efficiency (99%) and a level of safety (subject to high-quality electrics).

Connecting an electrode boiler

We will not describe in detail each stage of work. How to connect radiators, connect metal-plastic pipes. You can watch all these steps in the video instructions. The Galan electrode boiler connection technology is considered quite popular today.

As you can see, the installation is considered quite simple. Anyone can do it with their own hands. Now we will tell you about what rules you need to take into account when installing an electrode boiler with your own hands. An electrode boiler uses a lot of electricity, so it's best to look into cheaper heating options. To ensure your system is reliable, you need to consider the following recommendations:

Before connecting the electrode boiler, you need to configure the coolant. The Galan company recommends using a special liquid “Argus-Galan”. This fluid must be changed every 5 years. You also need to remember that it is strictly forbidden to use “Arctic” and “Antifreeze” liquids.

The old heating system must be flushed to remove salt deposits. Dirty radiators can negatively affect the density of the coolant. To flush your energy carriers, it is recommended to use a special inhibitor “Protector”.
The electrode boiler cannot be connected without grounding. We recommend using copper wire as a conductor. The ground wire must be connected to the terminal marked “0”.

The coolant consumption should be 8 liters per 1 kW of power. Thanks to this, you can reduce energy costs.
A deaerator valve must be installed at the highest point of the system. Also, connecting an electrode boiler cannot be done without installing a pressure gauge.

Shut-off valves must be installed behind the expansion tank.

The heater body must be installed in a vertical position. Any imbalance can negatively affect the operation of the system.
When choosing a radiator, the product must be installed from bimetal. These metals have fewer impurities and do not affect the electrode boiler.

When installing an electrode boiler with your own hands, you cannot use cast iron batteries. These products can get dirty quickly and therefore use a lot of heat.
If necessary, several heaters can be installed in series. It is fashionable to use a group of boilers in a two-story house.

Now you have learned how to connect an electrode boiler in a house or apartment yourself. As you can see, connecting the electrode boiler does not take much time.

We recommend reading: installing an instantaneous water heater.

Features of connecting electric boilers

Even for a non-specialist, the connection diagram for an electric heating boiler is clear, so installing the device will not be difficult. To understand how to install, you should know what devices you will be working with and what their purpose is.

So, during installation you will have to mount the boiler itself, various regulators, and an expansion tank on the wall (or on the floor). Depending on the purpose, one or more main circuits are connected to the boiler. Also, depending on the model, installation of a circulation pump and boiler unit may be required.

Before proceeding with installation, you should familiarize yourself with a document such as the connection diagram for an electric heating boiler, which the manufacturer encloses with the package of documents for the unit. In accordance with this document, the device is connected to other devices in the heating network.

It should be borne in mind that if the boiler power does not exceed 3.5 kW, it can be plugged into an outlet. Otherwise, electrical installation is carried out directly from the junction box.

Moreover, if the power of the device exceeds 7 kW, the use of a three-phase network of 380 V will be required. The boiler must be protected by an RCD and a circuit breaker.

We should not forget about grounding the wiring.
