Characteristics of the gas boiler BAXI Eco Four 24 F

For autonomous heating of the home, gas boilers are most often chosen. They are easy to use, operate on the cheapest and most affordable fuel, and are connected to any type of water heating. The gas boiler BAXI Eco Four 24 F from the Italian company BAXI is economical, compact and reliable.

Features of the gas boiler BAXI Eco Four 24 F

The Baksi double-circuit boiler is adapted for unstable gas flow and voltage drops in Russian networks

The double-circuit wall apparatus with a capacity of 24 kW is designed for heating rooms with a total area of ​​200–220 sq.m. It is equipped with a pump and operates on a forced draft.

The boiler heats water for heating and for domestic use. The heating circuit operates in two modes: when heating in the usual way - a system with radiators, the water heats up to + 30– + 85 C, and when connected to a warm floor, the temperature is set at + 30– + 45 C.

The device is adapted to work in Russian conditions - with unstable indicators of gas and current. The boiler shuts off when tipping over, changing position, or attenuating the burner. However, when the gas pressure drops, it does not immediately turn off - the pressure switch is turned on and the heating in the house is functioning. If the pressure rises above the norm - 3 bar - the gas is vented through the valve. The device is protected against freezing: with a sharp decrease in temperature, a pump is switched on, which increases the circulation of the coolant.

The Baksi Ecofar 24 boiler performs prophylaxis: once a day, an energy-saving circulation pump is turned on. This prevents blocking of the three-way valve.

Under normal conditions, the main parameter for adjustment is the temperature of the coolant and air. However, the unit is equipped with a weather-dependent control unit. If you purchase and connect an outdoor sensor to it, the boiler automatically calculates the operating mode taking into account the temperature in the street - when the temperature drops, the boiler increases heating, without waiting until the room cools down.

Another important feature of the BAXI Eco Four 24 F boiler is the ability to operate on different fuels. It is connected both to the gas main and to the cylinder with liquefied gas. When switching from one type of gas to another, it is necessary to change the gas nozzles and indicate in the settings with which fuel the device works.

Specifications

The user parameters of the BAXI Eco Four 24 F boiler are presented in the table.

Although the power of the device is 24 kW, they connect it to a single-phase network with a voltage of 230 V.

Boiler design

BAXI Eco Four 24 F boiler with atmospheric burner without front panel

The design of the device is not too different from its counterparts. Its advantages are a competent layout, and not an innovative technology, although some elements are a special development.

The main components:

• atmospheric burner Polidoro - takes air for combustion not from the room, but from the street;
• 2 heat exchangers - copper for heating and made of stainless steel for domestic hot water;
• Grundfos UP 15-50 circulation pump with automatic air duct, works in 2 modes;
• three-way valve made of brass with electric actuator;
• expansion tank membrane type, volume 6 l;
• safety valves - relieve water pressure in the heating system or hot water supply;
• electronic control unit with a sensor system.

The device is equipped with an LCD display, which reflects all current information. Damage information appears here.

All internal parts - the gas part, the supply pipes, the hydraulic part - are made of brass and are not susceptible to corrosion.

Advantages and disadvantages

There are turbocharged models for apartments and for installation in a chimney in a private house

The pros and cons of the Italian apparatus are due to its design and quality of parts. Advantages:

• Boiler BAXI Eco Four 24 F double-circuit - can heat the house and heat water for the bathroom and kitchen.
• The unit is automated. It is not difficult to configure it; the boiler develops the operating mode to ensure a comfortable temperature.
• Adapted to work with very low pressure and at low temperatures.
• A well-designed security unit, literally all situations are provided. Moreover, the boiler performs some actions to prevent them by itself.
• Works without interruption for more than 30 years.
• The system is equipped with pumps, but the boiler works almost silently.

Disadvantages:

• the boiler is volatile - when the current is turned off, operation is impossible;
• high price;
• tank volume is small;
• expensive parts, but repairs are quick.

The device is not too sensitive to water quality by European standards. If the water hardness exceeds 200 mg of calcium salts per 1 liter of liquid, it is necessary to install a polyphosphate filter to soften.

Errors gas boiler BAXI Eco Four 24 F

Error codes can be found in the operating instructions for the device

Gas boiler Baksi Ekofor is equipped with a self-diagnosis system. If any malfunctions are detected, the device pauses and signals a malfunction. The error code appears on the display. This simplifies the repair.

Most often, the following problems occur:

• E01 - the burner has gone out. There are many reasons: ignition error, sensor failure, lack of gas.
• E02 - overheating of the heat exchanger. Most often occurs due to the accumulation of plaque on the pipes.
• E03 - fan failure. The device must be replaced.
• E05 - failure of the temperature sensor OB.
• E06 - DHW temperature sensor failure.
• E10 - the pressure in the heating system has dropped. A possible cause is leakage of the boiler itself or pipes.
• E25-26 - pump failure. The same code may indicate a sensor malfunction.
• E35 - mixing media. It occurs when moisture appears on the board, breakdown of the sensor, the occurrence of a spurious flame.
• E26 - the voltage in the network is insufficient for the operation of the device.

When the code appears on the screen, press the "R" button and hold it until an error is reset. If after this a message appears again on the display, the malfunction is real and not caused by an accidental malfunction. You must call the wizard. Self-repair of a gas boiler is strictly prohibited.

You can use the restart option no more than 5 times, then the device is blocked.

Management and Security

The piping and connection check is carried out by a gas specialist

The first start-up of the boiler is carried out in the presence of a specialist. Then this procedure is carried out independently:

• They turn on the device in the network, open the gas valve.
• Press the start button and set the operating mode - summer or winter.
• Indicate the temperature of the heating fluid by pressing the +/- buttons. When the boiler starts, a fire symbol appears on the monitor.

At the first start-up, air plugs are often detected in the gas supply pipe. In this case, the burner does not ignite, an error signal appears on the screen. The team is reset by pressing the "R" button, and repeat the start.

4 operating modes are possible:

• Summer - the boiler only works for heating water.
• Winter - heating of the liquid and heating are carried out. Both icons are lit on the screen.
• Only heating is a more economical mode, so less gas is spent on heating the coolant.
• Off - No characters on the display. The machine does not work, but the frost protection function remains active.

To make the boiler inactive, disconnect it from the power supply.

Only a specialist can transfer the device to another type of fuel: for this, nozzles must be replaced.

To extend the life of the device, you must follow the instructions. Once a year, a specialist should be invited for a routine examination.
