Electric boilers evan epo 4 electric circuit. Before turning on the electric boiler, make sure that

There is no external remote control in it, since it is not needed. The temperature regulator is located on the boiler itself, in the upper end part on the heating element. The electric boiler is equipped with a cable and an euro plug, the power consumed is 220 V. It is very easy to install this device in the electrical network. It is well applicable in country houses, boxes, small garages where a high temperature in the room is not particularly needed. Another of the more frequent applications is to work in "pair" with another heat generator, such as solid fuel. At night, it turns on to maintain the temperature of the coolant in the system. The heating element is made of high quality stainless steel. The ability to control the temperature within 35-80 degrees, a connector for connecting the pump.
The boiler has been tested at the EVAN CJSC plant, certified, and has a 12-month warranty.

Electric boiler EVAN EPO 4 kW. Heated area: 40 m2. The price is for the boiler complete with 1-stage control panel.

Electric boiler EVAN EPO 4 is a stationary electric heater designed for heating residential, domestic, industrial and other premises.

All models of electric boilers EVAN EPO

Application should be considered in the following cases:

As the main source of heat (if there is sufficient allocated electric power and if it is impossible (or expensive) to connect to the gas distribution network;
- as a temporary source of heat for the period of construction work and laying of engineering communications;
- as a backup or additional source of heat during emergencies;

Installing an electric boiler as the main or additional source of heat in an existing or planned water heating system is not particularly difficult and, as a rule, does not require complex additional measures (for example, chimneys, foundations, window openings), subject to a qualified connection in compliance with electrical safety requirements.
For preliminary selection of the required power of the electric boiler, one can proceed from the calculation of 1 kW per 10 m2 of heated area. In rooms that meet modern requirements for heat loss, the specific electrical power can be significantly lower.
A wide power range of EVAN EPO electric boilers from 2.5 to 480 kW allows solving the problems of heating both a small country house and a residential building or production facility with an area of ​​​​up to 4800 or more m2.
Electric heating boilers EVAN EPO 4 can operate in heating systems with natural and pump circulation. Both water and non-freezing liquid can be used as a heat carrier. EVAN recommends DIXIS antifreeze for use.

The design of EVAN electric boilers provides for the choice of the desired temperature regime, depending on the air temperature in the room. To do this, the boiler control panels are equipped with a connector "Connector X1" for connecting a room thermostat. When using an air temperature sensor, the control circuit will automatically switch to work with this sensor. To do this, the "Temperature" knob on the boiler control panel must be brought to the maximum temperature mark and all power levels must be turned on. Further, the switching on and off of the electric boiler to maintain the temperature set by the room thermostat will occur automatically.

When choosing a room thermostat, it must be taken into account that it must contain a changeover contact. The connection of the room thermostat to the boiler must be made with a two-wire cable with a cross section of 0.5 mm 2.
EVAN EPO boilers are switched off when the sensor contacts are closed.

Thermostats (with built-in air temperature sensor) for controlling EVAN boilers:

Electric boiler EVAN EPO-4 (4.0 kW), diagram and connection procedure.

The electric boiler EVAN EPO-4 (4.0 kW) is operated with a protection device installed in the stationary wiring. Before trial switching on the boiler after connection, maintenance and (or) repair, make sure that the device has a zero protective conductor PE.

Before turning on the electric boiler, make sure that:

The absence of a break in the visible part of the zero protective conductor;

The absence of damage to the visible part of the insulation of the electrical wiring and the zero protective conductor PE;

The absence of visible leaks of the coolant from the device and the heating system;

The absence of a frozen coolant in the heating system;

The presence of coolant in the expansion tank.

Start-up and adjustment works include:

Connecting the boiler to the electrical network;

Filling the system with coolant;

Removal of air from the heating system;

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

Trial run;

Adjustment of the system and valves;

Before installing the boiler, check the correctness and quality of the installation of the heating system with natural circulation.
The pipes of the heating system must be located so as to promote the natural circulation of the coolant. In this case, the maximum level of the coolant should not exceed 30 meters to the level of the boiler (the 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, a circulation pump must be used.
The heating system must necessarily have an expansion tank that communicates with the atmosphere. When using a membrane-type expansion tank, a safety valve designed for a pressure of not more than 0.4 MPa must be installed before the ball valve at the outlet of the boiler.
Since when the safety valve is triggered, coolant or steam can be released through its drain hole, it is necessary to connect a drain to the sewer system to it.
Ball valves are installed at the inlet and outlet of the boiler, which are used during dismantling, repair and maintenance of the device.

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

Pressurization pressure of the heating system with the boiler after installation - 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.

Electric boilers of various classes, similar in electric power:

Electric boiler EPO class 4 "Standard-Economy" is the most budgetary model in the range of EVAN heating devices, which is suitable for use both at home and in the country. A 20% reduction in the price of the device, in contrast to the “Standard” class following it, is achieved due to the absence of a housing that combines the boiler and the control panel, while maintaining all the basic characteristics and capabilities. The required temperature of the heat carrier in the boiler is set by the built-in thermostat by smooth adjustment from 30 to 85 degrees. In addition, the boilers have the ability to connect an external thermostat, with which you can adjust the air temperature in the room. The GSM-Climate boiler remote control module (except for EPO-2.5) can be used as an external thermostat, which allows you to control the temperature in the room from a distance, control the operation of the boiler and monitor its serviceability. To ensure safety when heating to the set temperature of the coolant, the thermostat turns off the boiler and turns it on again after the temperature drops below the set one. For additional protection against overheating, the devices are equipped with a self-resetting emergency thermal switch, which, in the event of a failure of the main thermostat, turns off the boiler when the coolant reaches a temperature of 92 degrees. The heating elements of the EPO 4 boiler, like all EVAN electric boilers without exception, are made of stainless steel, which increases their service life.
