Characteristics of the hydraulic and gas system

The gas boiler has a hydraulic and gas system as a result of its features. Flame modulation is a feature of the gas system, and the branching is made of stainless steel. If a special kit is present, equipment can be made to operate on liquefied gas. A gas boiler is capable of running at pressures higher than 5 MBAR.

There are two heat exchangers in the hydraulic system. The first is made of stainless steel and is used to heat water. The second heat exchanger, which is composed of copper, is utilized for the heating circuit. There is a three-way brass valve installed inside.

The circulation pump operates quickly. The filter is installed at the hot water supply circuit’s output. Should the need arise, a solar collector can be linked to both the hydraulic system and the cumulative boiler. A manometer, which is regarded as post-cycling of the pump and automatic bypass, is also included in the apparatus.

The BAXI ECO Four 24 F stands out as a dependable option for home insulation and heating because it combines ease of use and efficiency. This article goes into great detail regarding how to use it to the fullest, covering technical specifications, common errors users may run into, and possible malfunctions.

For which rooms it is best suited?

Gas boilers with double circuits are best suited for heating and DOS of individual homes in the surrounding area. Because of the inconsistent working conditions and inadequate service, these units should not be used in public or industrial buildings.

These boilers are frequently purchased with the future in mind and are currently run as single-circuit installations (just for heating the building). This strategy is completely justified because, should the opportunity present itself, only the relevant pipelines will be connected, and the cost difference will not be appreciable.

In order to obtain a large margin of safety, users frequently purchase Baxi Eco Four 24F boilers to organize heating apartments that are significantly smaller than planned.

As work in an abnormal mode is just as damaging to the unit nodes as overload, expectations are not always warranted.

Baxi Eco Four 24

The main copper alloy heat exchanger in the heating circuit is fitted with the BAXI ECO 4S 24 model. Its heating surface efficiently transmits the heat from the heat generator to the heat carrier produced when the gas burns.

The stainless steel heat-intensive plate type for the DHW contour heats water for domestic use to a temperature of up to 55 degrees Celsius nearly instantly.

The Grundfos electric pump, a well-known Danish brand, is used to forcefully move the coolant along the heating circuit and devices.

An air tower on the Grunlfos pump is used to lower air when the heating network is turned on. It is utilized with DHW and a single-circuit boiler for various fuel kinds.

A closed expansion tank is fitted in the boiler to guard against system ruptures brought on by the fluid’s temperature expansion during warming up.

The manufacturer permits the use of processed, purified water or antifreeze as a heating medium in the ratios indicated in the boiler’s operating instructions. 670 m3 of liquid can flow through the pump in its entirety each day.

The Baxi Eco Four 24F unit can connect an indirect heating boiler with hot water accumulation to the hot water boiler in case the boiler owner needs to increase the volume of load in the hot water supply system.

What functions has

The following options are included in the boiler’s functionality:

  • Heating and organization of the coolant circulation (OV) in the heating system of the house.
  • Heating and serving to the points of analysis of hot household water.
  • Ensuring control over the activities of the main nodes using a self -diagnosis system.
  • Setting the operating modes, adjusting heating parameters and downside.
  • The heating circuit can be used both for the open system and for the warm floor with a limitation of the temperature of.
  • There is a possibility of connecting external temperature sensors (weather -dependent automation) and room temperature (thermostat).

NOTE: A daily pump is launched to pump water through the valve and move the structure in order to keep a three-way valve in operational condition and eliminate the chance of jamming and blocking it.

Temperature control characteristics

Two levels of temperature adjustment are possible with a wall gas boiler:

  1. In the "warm floor" system – from 30 to 45 degrees.
  2. In the heating system – from 30 to 85 degrees.

In addition to the weather-dependent automation that is already built into the equipment, an external temperature sensor can be attached. The temperature regime in automatic mode is controllable within the hot water and heating circuit. You can learn about the temperature of the hot water and heating system thanks to control. The equipment can be connected to an indoor thermostat and programmable timer.

Launch instructions

Once the boiler is delivered and unpacked, it is installed in the designated location and the relevant pipelines are connected. Both the service center’s personnel and independent contractors are capable of carrying out these tasks.

After that, the following procedures are followed:

  • Open all the taps of the heating system (input and output), the boiler is disconnected from the power.
  • The pressure in the expansion tank should be 0.5 at.
  • Open the crane and fill the heating system to a value of 1.5 AT (green sector on the pressure gauge).
  • Block the crane and lower the air in heating devices (radiators, convectors, etc.P.). Because of this, the pressure will drop. Repeat the procedure until all the air is removed, and the pressure will not be a little higher than 1.
  • Remove the lid and unscrew the plastic panel screw, opening access to the circulation pump. It has its own screw with which air is removed.
  • If the air comes out, the pressure in the system drops, so it must be checked and, if necessary, raise it to 1.
  • Without dressing the lid, turn on the boiler in heating mode for 1 minute at temperatures up to 50 °. The circulation pump will turn on. Perhaps various errors will be displayed on the display. This is normal, since the system has the remains of air that prevent the sensors from correctly displaying the situation.
  • After a minute, turn off the boiler and open the pump screw again. Air will exit in noticeable quantities.
  • Repeat the start procedure in the same mode for 1 minute and again shake the air. Repeat until the air is completely removed.
  • After that, leave the pump screw unscrewed by a quarter or half turnover for self -removal of air.
  • Put the boiler into the "Summer" mode, check if hot water is coming from the crane. If this did not happen, and the burner started for a few seconds and turned off, you should turn off the boiler and turn the power plug in the outlet. Phase -dependent boiler and will not work correctly if the fork is not so turned in the outlet.

Following the proper connection, the location of the vlok in the outlet should be marked with a marker so that the installation can be turned on right away.

Gas boiler operation instructions

Boilers do not require any basic requirements to operate. The manufacturers have thought of every scenario and have included the appropriate error codes to represent them.

The user only needs to promptly address their appearance in order to resolve any issues that may have emerged on their own or with the assistance of an invited specialist.

Additionally, once a year maintenance on installation, scale and soot removal from the boiler, and other necessary work must be done. It is not advised for individuals to participate in such activities independently; instead, the service organization’s forces handle this.

Functions and management

The BAXI ECO Four 24 F heating unit has an advanced electronic self-diagnosis program that can recall the most recent malfunctions in its operational systems.

The boiler can be controlled in four ways:

  1. “Summer” – the regime is intended for the warm season for heating hot water, when using the boiler in the autumn period, the mode has the “freezing protection” function so that the device is not damaged during random frosts.
  2. “Winter” – the mode allows you to heat water for two contours – heating and DHW, with the working function “Protection from freezing”.
  3. “Only heating” mode allows you to heat water only for heating, with the working function “protection against freezing”.
  4. "Turned off" – the boiler does not work.

The temperature value in the shapes of the heating and hydraulic devices, along with an icon indicating the presence of a torch on a burning device, are displayed on the LCD panel while the boiler is operating.
