The device and operation of the electric boiler Evan EPO

Choosing a heating method

A private house, a cottage always assumes autonomous heating. His choice depends on many factors:

• the presence of gas and electric lines;
• wishes of the owner of the cottage.

What type of heating the homeowner will prefer is his capabilities and taste:

• to install a stove heating or fireplace in a house, you will need to consult a specialist and a master for laying these devices for heating a house;
• water heating at home will require such heat generators as boilers, water heaters operating on gas, liquid and solid fuels, electricity.

Using gas as fuel is a very long and expensive procedure.

Electricity is a very convenient option for heating your home. Installing electrical equipment and connecting it to the wiring of the heating system will not take much time. Heating tariffs for settlements outside the city are quite low. The advantage of electrical devices is that, being a simple device, they imply the possibility of complete automation of the device to create the necessary healthy indoor climate.

Choosing a heater is an important problem. For every home owner, it is desirable that this device be reliable, safe, easy to operate and maintain, and serve for many years without accidents.

To increase comfort and reliability, electric boilers can be equipped with a pump, a tank for receiving heated liquid, an overpressure valve, and an automatic control circuit.

Among the most simple, but reliable devices, the Evan electric boiler stands out. The characteristics and cost of the device will suit many homeowners.

Important Tips

You can see that the Evan Warmos boiler and Epo Evan boilers of various models are quite simple to install. In addition to the above installation steps, we also want to give some simple recommendations that can greatly simplify the installation process:

1. If the heating system to which you will connect the boiler has already been in operation before, we recommend flushing it with cleaning agents.
2. An electric boiler is optimal for additional space heating, but not as the main source of heat.
3. If the selected boiler is electrode type, it will also be necessary to install an air vent and a non-return valve.
4. Install shut-off valves if using an open system.
5. When installing a new boiler, leave free space on at least one side, so that in the event of a breakdown or malfunction, you have free access to it.
6. Install a filter on the return pipe of the heating system.

An electric boiler is an excellent tool for creating a high-quality autonomous heating system. This is very convenient if you are not connected to a central heating system. One of the advantages of modern boilers is the presence of a temperature control sensor depending on the time of day and night and the temperature outside the window. In fact, this is a small boiler room.

In operation, modern domestic-made Evan boilers are simple and convenient. They are ideal for families with small children, because they are completely safe. During operation, the most important thing for you is to monitor the boiler's health and clean the heating elements from scale in time.

General principles for connecting electric boilers

It is not difficult to connect a household heater, since the devices can be connected to the network using a regular electrical outlet, provided that their power is not higher than 3.5 kW. Almost all household electrical heating devices have a maximum power of about 24 kW.

Evan, a well-known manufacturer of electric heating boilers in Russia, has electrical appliances in its range, the power of which is determined by the value of 240 kW.

Devices, the power of which is measured from 7 kW, are connected to 380 volt power lines. In both versions, electric boilers must be individually connected to the power supply.

Evan's company specializes in the production of single-flange electrical devices (the exception is Professional class boilers), using a tank for heating the coolant made of alloy steel, treated with a special anti-corrosion compound. The thickness of the heating container is 3 mm. Electric boilers of the Comfort class are made of a special material with high thermal insulation and a wall thickness of 20 mm. The period of operation of such a device is calculated for a period of at least 30 years.

Electric boilers on heating elements

As a converter of electricity into heat, the corporation uses unique devices for its boilers, heating elements. These structures are made of alloy steel in the form of tubes. The resistance of the heating element is calculated at 100 Mohm. This figure exceeds the safety requirements of not only Russian manufacturers.

For the company's devices, only two types of breakdown are possible:

• destruction of the internal heating element of the heating element as a result of the burnout of the spiral;
• violation of the integrity of the heating element by a breakdown.

The occurrence of these malfunctions is due to two reasons:

• deposition of solid sediment on heating elements, formed as a result of the precipitation of salts of the hardness of the coolant as a result of its heating. The sediment covering the heating element prevents heat removal from the heating element, which causes it to burn out;
• voltage drops in the network can lead to the destruction of the integrity of the heating device;
• evaporation of water leads to overheating and, as a result, the heating element burns out;
• electric heating boiler Evan, which uses heating elements in its design, loses in size and weight.

• the ability to connect a circulation pump to improve the movement of the coolant in the system;
• the presence of a remote sensor for controlling the air temperature in the room;
• connection of a water heater for additional indirect heating.

Material for heating elements - alloy steel.

The Evan epo 4 electric boiler is often built in as an additional device for heating a room in an already equipped water heating circuit. This operation is straightforward. When adding a boiler to an existing heating system, the procedure for connecting the electrical part is of prime importance.This stage must be performed by qualified performers.

The use of the EPO boiler is based on its wide power range from 2.5 to 480 kW. Heating of light suburban structures and capital housing construction is possible with EPO series electric boilers. Premises with an area of ​​4800 m2 and more are heated by a heating system with an Evan EPO boiler using natural and pumping circulation. The electric boiler Evan epo 4 can use water or liquid with antifreeze additives as a heat carrier.

The design of the electric boiler Evan EPO-4 allows you to place it on the wall. This option is especially preferable for small spaces.

• electric boiler Evan epo 6 maintains a comfortable room temperature regardless of low external temperatures;
• for this boiler design, it is possible to connect room temperature sensors, which increases its cost.

Despite the simplicity of installing an electric heating boiler into a heating circuit, it is necessary to follow some mandatory instructions:

• the location of the pipes connecting the Evan electric boiler with water heating radiators should be performed with a certain slope to ensure the natural movement of the coolant through the system;
• the impossibility of fulfilling this condition, a circulation pump is installed in the system;
• the presence of an expansion tank in the heating circuit, where the electric boiler Evan epo 6 is used, is mandatory .. Using a membrane-type tank, a safety valve must be built-in in front of the valve;
• the boiler inlet and outlet must be equipped with ball valves required for repair and dismantling works;
• vertical installation of the boiler;
• for the control panel, it is recommended to install it at a height of about one and a half meters from the floor, in a room with good lighting;
• The heating system installation manual strictly prohibits the installation of shut-off valves in the heating system.

Boiler installation

In order to independently install the electric boiler, you will need:

• instructions that come with the kit;
• drill (preferably electric);
• profile;
• hardware, with the help of which the equipment will be mounted on the wall;
• cable of a certain section;
• installation bar;
• flanges, couplings;
• level;
• electric wire;
• fasteners;
• pipes;
• a set of keys;
• Evan boiler connection diagram.

Do not forget to check whether the wall on which the boiler will be installed is really strong enough.

Installation steps and progress

When you have made sure that you have all the necessary tools, and the wall surface meets the strength requirements, you can start connecting the Evan boiler. Perform all work according to the following plan:

• Using a level and a simple pencil, mark the future location of the boiler on the wall. Try to place it away from the water supply. Electricity and water supply are incompatible.
• Measure where the fasteners will be and drill the holes for the fasteners at the desired distance.
• Install the strip and mounting profile. Use a spirit level and see how level the mounts are. It is imperative that the boiler is held firmly and tightly (although Evan boilers are light enough, we do not recommend installing them on flimsy walls. In this case, it is better to use a floor boiler).
• Fix the boiler to the wall using dowels.
• If you have chosen a floor standing boiler, place a stand on the floor.
• The next step is grounding. Many ungrounded boilers simply won't work. Or, the indicator on the panel will flash continuously. To ground a new boiler, make a grounding center. This is a design of several metal pins that are connected to each other with conventional fittings. All this is buried in the ground. Lead the zero wire to the pins. Excessive voltage will now be immediately discharged to the ground. A 0.4 cm copper cable is best for grounding.

Important! Ungrounded or improperly grounded boilers are really dangerous to health and life. The use of ungrounded equipment is strongly discouraged.

• After suspending the boiler and grounding it, run a cable of a certain cross-section to it. To connect a three-phase boiler, connect wires M1, M2, M3. In this case, the zero cable is connected to the bus on the shield - in this case, grounding will occur through it.
• For safety reasons, install a residual current device near the boiler.
• Route the wires for the temperature sensors and the shutdown timer.
• Install the electric pump and expansion tank. To do this, use fasteners. In some models, they are already installed in the boiler. Install the pump on the water supply pipe next to the boiler.
• Connect the boiler, expansion tank and electric pump to each other with metal or reinforced-plastic pipes (note that reinforced-plastic pipes last longer and do not corrode).
• Hide the wires in cable channels and install a protective cover for fire safety.
• Now you can connect the boiler to your heating system. Use couplings and flanges to connect the boiler and piping.
• The final step is connecting to the network. First, make sure to properly ground and connect all wires. Check the instructions. Please note that the distance between the contacts is at least 0.3 cm. When everything is done, turn on the water supply and check how the boiler works.
