Before the purchase! When choosing a UPS, you first need to know the total electrical power of the system. From the table below you can take the power value for your model boiler Baxi. However, do not forget to add the power of external (additional) circulation pumps (if they are installed, for example, on heated floors).
Correspondence table between Baxi boiler models and their power consumption.

Recommended On-Line UPS kits with batteries for Baxi boilers
UPS kits up to 800W with external batteries
- UPS - it is responsible for the quality of processing of incoming voltage (in in this case- this is On-Line), for monitoring the presence of voltage and timely transition to battery power, for charging the batteries.
- Battery pack - it is responsible for time battery life, the greater the capacity of the batteries in the block, the longer time reserve. Their service life depends on the quality of the batteries themselves.
24v UPS with two external batteries: - optimal price-reliability-efficiency ratio
Our company’s engineers have created for you a unique program for selecting a UPS model for a boiler and calculating the required battery capacity. By specifying the power and desired autonomy time, all options are displayed. Use the automated selection system
Please pay attention: What parameters must the electrical network have in order to connect a boiler to it?
Everything is standard here: 220 V, 50 Hz, grounding. In principle, the same requirements as for connection, e.g. washing machine. Grounding must be carried out according to all standards. If there is any potential hanging on it, which often happens, we must fight it. In the absence of normal grounding, it is recommended to install a special stabilizer that provides separate galvanic isolation. It often happens that potential comes along gas pipe. Then the boiler must be connected via a dielectric adapter.
BAXI boilers operate stably in the range from 170 to 250 V.* At 170 W modern models BAXI boilers are switched off. And when the voltage increases above 250-270 V, the protective element (“varistor”) burns out on the board.**
The very characteristic of electricity in the network is sine wave- must be free of interference, therefore the use of uninterruptible power supplies designed for computer equipment and producing a rectified current characteristic is not recommended. Many service organizations When commissioning boilers, they prefer to additionally install a voltage stabilizer. It is recommended to connect boilers to the electrical network through a separate circuit breaker. If the boiler is phase-dependent, it is necessary to ensure that the phase and zero match. This information is from the official website
Note* At a voltage of 180-170 volts, circulation pumps heat up more and their service life is significantly reduced.
** "Varistor" is a protective element that, when burned, prevents damage to the boiler electronics. The varistor is replaced only at Baxi service centers. The ready-made kits offered below are suitable for Baxi wall-mounted boilers of the Four, Luna, NUVOLA series with a consumption power of 80-135 W.
This is just one of many options to provide uninterruptible power supply boiler We individually calculate the optimal options based on your data on power and desired autonomy time. There are no “ready-made” kits as such; they are assembled from two main components:
How many batteries should I buy and what capacity? The number of batteries depends on the selected UPS model and is related to the inverter voltage of a specific UPS model. For example, it has proven itself well during the period " freezing rain"The Inelt Monolith K1000 LT UPS requires THREE 12-volt batteries for its power supply. You can calculate the capacity using the formula below.
Where: T- desired system autonomy time in hours.
R- load power (taken from the passport for the boiler or pump) in watts.
N- the number of batteries on which the selected UPS model operates.
The battery life depends only on the capacity of the batteries and their quality and does not depend on the manufacturer, brand and model of the UPS!
There is a discrepancy in the data on the autonomy time of each manufacturer with the data obtained during the calculation using the above formula. This is explained by the fact that the formula takes into account two reduction factors. This is the converter efficiency and coefficient. discharge depth. Therefore, the estimated time according to this formula will be slightly less, than in technical descriptions the UPS itself and is more reliable.
Let us give the procedure for accurately calculating the autonomy time, for example for a gas boiler BAXI NUVOLA-3 Comfort 240i. initial data nameplate electrical power consumption 110 watt, and it is necessary to ensure uninterrupted power supply from the UPS for a period 12 hours.
According to the formula for calculating the battery capacity of 110W, we multiply by 12 hours, divide by 8.65 = 152.6 a/hour. This is the total capacity of the battery. T.K. UPSs operate from two or three batteries 150 divided by 2=75 or 3=50. Bottom line, choose a UPS that runs on two batteries and to it two batteries of 75 A/h or a UPS operating from three batteries and to it three batteries, 50 a/h each. 50a/hour no, it means close to 55a/hour. Battery options are in the table below. These are not all options batteries which we have in stock or are available to order. If you go to the battery section, set the desired capacity range, you will be able to select other options in terms of price and quality.

— brass three-way valve with electric servo drive;
- expansion membrane tank volume 6 liters.
As we can see, all the main elements of the Baksi Eco For 24 F gas boiler have been produced well-known companies, world leaders in their industry. Besides, everything internal parts made of brass: hydraulic group, supply pipes and gas part. The boilers are adapted to Russian frosts and are able to function even at very low gas pressure.
Design and principle of operation of the Baxi Eco Four boiler
The boiler's gas burner has stainless steel nozzles and smooth flame modulation with smooth electronic ignition, as on all budget units from this manufacturer. Specially designed system automatic regulation air supply to the device is protected by a patent.
Functions, control and safety
As with all models of fourth-generation Baksi boilers, on the front side of the wall-mounted unit “Eco Four 24 F” there is a control panel with an LCD display, which displays and sets settings and parameters, temperature in the heating circuit and DHW. In addition, they appear on it when malfunctions or malfunctions occur during the operation of the boiler.
The heating circuit of the Baxi Eco Four boiler can operate in two modes:
- traditional (30-85 °C);
— warm floor (30-45 °C).
Like the boilers of the “Main Four” series, all “Baxi Eco Four” devices incorporate weather-dependent automation that helps the boiler operate depending on the temperature outside the window. All you need to do is buy a sensor outside temperature, install and connect it to the boiler.
Purchase and connection room thermostat It will also help save money, because the operation of the boiler, in this case, will depend on the set air temperature in the house or apartment.
Baxi Eco Four boiler control panel
Baxi Eco Four 24 F boilers are equipped with modern elements safety: a pneumatic relay (draft sensor) is triggered when there is insufficient draft in the chimney, when the pressure in the heating system is low, a special pressure switch is activated, and when it is excessive, a 3 bar safety valve is activated. There are flame control sensors, temperature sensors on the heating circuit and running water, pressure gauge.
Energy saving circulation pump Grundfos UP 15-50 automatically turns on once a day to prevent the three-way valve from blocking or jamming. This function is very useful when the heating device is idle for a long time and not used.
Also, the boilers of this series are equipped with a modern self-diagnosis system: the device itself periodically tests the operation and reports any problems on the LCD display. It is also possible to connect to bottled gas by first changing the gas injectors for liquefied gas.
Baxi Eco Four 24 F: technical characteristics of a gas boiler

Today we left a review of the popular dual-circuit wall model boiler for heating - technical characteristics, device according to the operating instructions. Reviews from owners and specialists are quite contradictory, but the undoubted advantage of the EcoFor series devices is the presence in them of two separate heat exchangers, a brass hydraulic group and a Grundfos brand pump. Let's watch the video.
Any user of a gas boiler wants his unit to work as efficiently as possible and at the same time economically. For the whole heating season economical device allows you to save a lot Money. Therefore, unit owners often look for an answer to the question of how to reduce the consumption of a gas boiler.
The amount of energy consumed depends on fluctuations in the outside air, so this indicator is constantly changing.
An ideal source of thermal energy must meet the following requirements:
- Produce enough energy to provide sufficient heat to a house or apartment.
- Be able to adjust the production thermal energy in a wide range.
- Have high efficiency.
- The device must be equipped with an automatic system that will regulate the power of the unit depending on the temperature indoors or outdoors.
To reduce the fuel consumption of a gas boiler, you need to know factors influencing this indicator:
- The degree of insulation of the house - the material of the walls, the thickness of the masonry, the tightness of windows and doors.
- Gas boiler power.
- Unit efficiency.
- Equipped with automation that can change the operating mode depending on weather conditions.
- Availability of additional power consumers: DHW circuit, “warm floor” systems, etc.
- Heat exchanger clogged gas burner boiler or chimney.
To reduce fuel consumption, it is necessary to adjust the presented factors whenever possible.
How does home insulation affect gas consumption?
A well-insulated room can save up to 35% of the heat produced. It is best preserved in a house with walls two bricks thick. More thermal energy will be needed to heat a panel or wooden cottage. But the situation can be improved by insulating the walls.
A lot of heat also escapes through the roof and floor. Therefore, in order to reduce gas consumption, it is advisable to insulate the ceilings and floors.
If you have old wooden frames and ventilated doors, they should be replaced with more airtight ones, otherwise the heat will quickly escape through the cracks to the street.
Gas boiler power
Before purchasing a unit, it is important to correctly calculate its required power. It is determined using special formulas taking into account the heated area, wall material, weather conditions of the region, etc.
Some do big mistake when purchasing a unit with too much productivity. This leads to “clocking” of the device - the unit quickly heats the coolant to the set temperature and turns off, then the liquid cools down and the device turns on again. This happens all the time. As a result, the boiler components wear out greatly, the service life of the device is reduced, and gas consumption increases. It is known that the greatest wear and tear on any equipment occurs during startup. Frequent switching on of the unit negatively affects many of its elements:
- burner;
- gas and three-way valves;
- circulation pump;
- coaxial chimney fan.
At the moment the burner is ignited, the maximum amount of fuel is supplied to it and when turned on frequently, the gas consumption increases. Some of this fuel goes into the pipe before ignition.
Unit efficiency
Gas boilers with high efficiency are more economical. Therefore, when choosing a device, you should pay attention to this indicator. For example, units with an open combustion chamber have a low efficiency - from 80 to 88%, since part of the heat, along with the flue gases, escapes through the chimney. Boilers with a closed combustion chamber have a higher coefficient - 90-94%.
Most best efficiency in condensing units, which are considered the most economical. Their figure is 96-99%, but the cost of such gas boilers is higher.
Weather-compensated automation
Weather-sensitive automation will allow you to use fuel to the maximum benefit. It records the temperature outside and, depending on this, selects the heating agent heating rate. Thus, the system maintains the air temperature in the room at a given level. Therefore, it is recommended to purchase a boiler that has this function built-in.
If gas device does not have such a system, it can be purchased separately and connected, but such automation will be quite expensive.
Additional gas consumers
Various types of fuel consumption significantly increase additional functions and systems connected to gas boiler. For example, DHW system increases gas consumption by 20-30%. The “warm floor” system will increase consumption by another 20%.
Note! If you connect a boiler to a single-circuit unit of lower power indirect heating, then it, heating the room and producing hot water, will work more economically than a double-circuit boiler.Clogged heat exchanger, gas burner and chimney
Fuel consumption increases due to blockages in the gas boiler elements:
- Scale accumulations in the heat exchanger of the unit. Lime deposits formed during operation prevent rapid heat exchange between the circuit and the coolant. As a result, in order for the liquid to reach the set temperature, the burner needs to heat the heat exchanger longer. To eliminate the problem, you need to remove the element, wash it with a solution and clean it with a brush.
- Gas burner clogged. Gradually, the burner nozzles or its igniter become clogged with soot and soot, which subsequently prevents the passage of gas and maintaining a stable flame. As a result, the burner must burn more gas in order to heat the coolant to desired temperature. The problem can be solved by cleaning the boiler gas burner.
- Chimney blockages. The soot and soot accumulated during the combustion process clog the pipe for removing combustion products, which disrupts the air supply to the burner, which disrupts the stable combustion process. Proper air supply and smoke exhaust reduces gas consumption. Lack of oxygen leads to a decrease in the amount of heat released during combustion and to the formation of soot.
These defects can have a long-term effect Negative influence and not be noticed by the owners. To prevent this, it is necessary to clean the boiler elements every year.
