So, we told you what Baksi brand gas boilers are, you familiarized yourself with key features the most popular models and found out what are the average prices for the products of this brand.

The actual total gas consumption for a certain period of time practically does not depend on the power of the boiler, but depends on the heat loss of the heated room, the mode of operation of the equipment and the amount of water used in the hot water circuit (DHW).
In the passports of gas boilers, as a rule, gas consumption is given at minimum and maximum power. Gas consumption is usually given for standardized gas types (G20 - natural gas methane, G30 - liquefied gas butane, G31 - liquefied gas propane).
For an "average" imported boiler with an efficiency of 90%, the total gas consumption at a load (net power) of 10 kW is approximately equal to:
– 1.2 m3/h for natural gas (G20);
– 0.86 kg/h for LPG (G30 or G31).
When calculating natural gas consumption, it should also be taken into account that in Russia, the lower calorific value may differ from standardized G20 gas downwards (up to 10–15%).

Reference data:
Lower calorific value of gases:
– for natural gas G20 (methane) is equal to 34.02 MJ/m3;
- for liquefied gas G30 (butane) is 45.6 MJ / kg;
- for liquefied gas G31 (propane) is 46.3 MJ / kg.
Values are at 15°C and atmospheric pressure 1013 mbar (760 mm Hg or 1 atm).

The exact gas consumption for non-condensing boilers can be determined by the formula: Gas consumption (m³/h or kg/h) = 3.6 Power consumption (kW) where

About the joint operation of BAXI boilers

ADVANTAGES OF USING SEVERAL BOILERS FOR ONE HEATING SYSTEM

An increasingly popular solution among installation and design organizations is the use of several boilers for one heating system. Such a solution is justified with a thermal load already starting from 40 kW. This can be either a large heated area, or the presence of thermal loads in the form of pools, garages, baths, greenhouses, etc.
The use of several boilers for one heating system has a number of advantages compared to one boiler with the same total capacity. We list some of these advantages.
Firstly, several small boilers of smaller dimensions and lighter weight are much easier and cheaper to transport to the boiler room and install there instead of one large and heavy boiler. (Especially relevant is this moment when installing roof or semi-basement boiler rooms.)
Secondly, the reliability of the system is significantly increased. If one of the boilers is forced to stop, the system will continue to work, providing at least 50% of the power (if two boilers are installed).
Thirdly, maintenance is facilitated by smaller size each boiler. can be carried out without stopping the entire system and.
Fourthly, the total resource of boilers increases. In autumn-spring time, only a part of the boilers can be operated by turning off some of the boilers manually or using cascade automation.
Fifthly, if in the future it will be necessary to replace any part of the boiler, then it is known that parts for boilers of lower power are more accessible and cheaper due to the greater serial production. It goes without saying that service work must be carried out by trained and competent personnel. Professional specialists will be able to perform a fairly large range of work directly at home with client clients. For several years we have been repairing gas boilers and servicing, while constantly supplementing and improving the services provided. This became possible thanks to the high qualification of each of our masters.

Gas appliances gained popularity thanks to high efficiency, which is produced during the combustion of fuel. In addition, the exhaust gases contain a minimum amount harmful substances. At the time of buying heating equipment we want to get an efficient and economical device. Therefore, it is important to calculate in advance the actual gas consumption in the boiler.

What factors affect fuel consumption

Years of use different types fuels proved that gas is 30% cheaper than diesel and electricity. Most users connect to a common line, as when using gas in cylinders, funds are spent on delivery.

Factors to consider when choosing a heating boiler so that there is no high fuel consumption:

Thermal losses. The consumption of a gas boiler directly depends on heat loss through walls, windows, doors, and a roof. Therefore, preliminary calculations technology power. The area of \u200b\u200bthe room, the quality of insulation, the purpose of neighboring rooms are taken into account.

Settings system. Automatic installation includes sensors that record the temperature external environment and configure the operation of the unit in optimal mode. This allows you to save on consumption.
Technology type. When using a condensing unit, gas consumption is reduced by 15–20%. Unlike the conventional convection type, the condenser contains a separate heat exchanger to direct the energy of the combustion products to heating the system. This increases the coefficient of performance (COP) up to 100%.

The presence of one or two circuits also matters. A single-circuit device works only for heating. Whereas double-circuit - for hot water supply (DHW) and heating. Therefore, its consumption will be higher.

Units with a closed combustion chamber consume less fuel than with an open one. The duration of the heating season also affects. After all, in winter the boiler operates at maximum, while in summer - at a minimum, only for heating hot water.

Why appliances consume a lot of gas? The fault is the poor insulation of the building, scale deposits.

The table shows an example of maximum consumption for 210 days.

Equipment power (kW)	How much gas it consumes (hour/m³)	Consumption for the whole season (m³)
10	1,12	5 644
12	1,6	8 064
15	1,68	8 467
20	2,6	13 104
24	3,1	15 624
30	3,9	19 656
40	5,2	26 208
50	6,5	32 760
60	7,9	39 816
100	13,1	66 024
200	26,2	132 048

Knowing how many cubes it takes per hour, you will calculate the rate per day and per month.

How to calculate fuel consumption

For heating a private house or apartment, calculations are used that are based on two parameters: the power of the heating equipment and the area of \u200b\u200bthe room. An average calculation is taken - 1 kW per 10 m².

Many articles have been written on this topic, but few specify that the kilowatt unit is thermal power and not electrical. This is confusing for many users.

It would be more logical to measure work on natural gas in cubic meters (m³ per hour), and on liquefied gas - in kilograms (kg / h).

On average, 0.112 cubic meters per hour of main gas is consumed per 1 kilowatt of thermal power.

For example, take the unit "" with a capacity of 17.4 kW. The passport data indicate the consumption of main fuel 1.87 cubic meters, liquefied gas - 1.3 kg / hour. These values are valid for continuous operation, but if the device is constantly working for wear, then the parts will quickly fail. When choosing, throw plus 20% to the indicated power.

"AOGV" in our example will be installed in a room of 140 m². Now take a look at the rates (roughly):

Natural fuel: 3.9 rubles per cubic meter.
On bottled gas, the calculation is based on the volume of the container. For 50 liters - 600 rubles. The cylinder is filled with propane not completely, by about 80% (21 kg). So: 600/21= 28.6 rubles. You can add shipping costs to this.

The calculation per day for the main connection will be as follows :

Day (24 hours) x 1.87 (cubic meters / h) / 2 = 22.4 cubic meters. To find out the cost: 22.4 x 3.9 (tariff) = 87.5 rubles.

Per month:

22.4 (daily consumption) x 30 (number of days) = 672 m³.

Per year (seven months - heating season):

7 x 672 (monthly rate) = 4,704 m³.

Working on propane per day :

24 (hours) x 1.3 (kg / h) / 2 = 15.6 kg. To find out minimum costs: 15.6 x 28.6 (tariff) = 446 rubles.

Per month (30 days):

15.6 (per day) x 30 = 468 kg. It turns out that you use 22.3 containers of propane per month.

For a year (seven months):

7 x 468 (per month) = 3,276 kg or 156 cylinders.

Keep in mind that these calculations are for one model only. Each brand has different values, you need to look at the documentation. See tables below:

And also for bottled gas:

Consumption is affected by the location of the device: floor or wall. Heat exchanger material, type gas burner, the number of working days.

How to cut costs

If you follow our recommendations in the domestic sphere, then you can save on the use of the boiler:

Start by choosing a technique. It is considered the most economical. It saves up to 25% of fuel, and the efficiency reaches 100-110%. Of course, its cost is much higher, but, according to experts, it will quickly pay off. Pay attention to customer reviews when buying. uses 20-25% more thermal energy. Therefore, if the room needs only heating, give preference to a single-circuit installation.
Take care of wall insulation, install plastic double-glazed windows. Heat loss through the roof is easy to determine by the growth of icicles. The more heat escapes, the more icicles. In this case, cover the roof, use special materials for insulation.
choose modern technology on automation. Manufacturers knowingly install sensors, thermostats and regulators. This system works as a single organism, automatically adjusting and adjusting the operation of the equipment to the conditions in the room. Timers and special modes allow you to maintain minimum values during vacation or weekend. And also you can choose the mode "Winter - Summer".
Do routine maintenance once a year. Be sure to call a specialist technical inspection. Keep debris clear of parts. Accumulation of scale on the heat exchanger contributes to an increase in the use of thermal energy. Remove soot and soot from the burner nozzles, clean the chimney in a timely manner.
Install a heat accumulator (TA). This buffer capacity accumulates coolant and retains heat for a long time (according to the principle of a thermos). Even when the boiler is turned off, the TA will supply liquid to the radiators. Using such a buffer saves 20–30% of fuel.
Do not select the maximum temperature. Set comfortable indicators, because against the background of average monthly consumption, even 1-2 degrees matter.

This is how heating costs are calculated. If you are not sure about the accuracy of the calculations, contact a specialist. He will take into account all the nuances and help you with the selection of economical equipment.

Before the purchase! At choosing a UPS First of all, it is necessary 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 underfloor heating).

The engineers of our company 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 the desired autonomy time, all options are displayed. Use an automated selection system

Please pay attention: What parameters should the electrical network have in order to be able to connect the boiler to it?

Everything is standard here: 220 V, 50 Hz, grounding. In principle, the same requirements as when connecting, for example, washing machine. Grounding must be carried out in accordance with all standards. If some potential hangs on it, which often happens, this must be fought. In the absence of normal grounding, it is recommended to install a special stabilizer, which provides a separate galvanic isolation. It often happens that potential comes along gas pipe. Then the boiler must be connected through a dielectric adapter.
BAXI boilers work steadily in the range from 170 to 250 V.* At 170 W modern models BAXI boilers are turned off. And when the voltage rises above 250-270 V, the protective element ("varistor") burns out on the board. **
The very characteristic of electricity in the network - sinusoid- must be free from interference, so use uninterruptible power supplies designed for computer technology and issuing a rectified current characteristic is not recommended. Many service organizations, when commissioning boilers, prefer to additionally install a voltage stabilizer. It is recommended to connect the boilers to the mains 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 get hotter and their service life is significantly reduced.

** "Varistor" - a protective element that, when burned, prevents damage to the boiler electronics. The varistor is changed only in Baxi service centers. The kits below are suitable for wall-mounted Baxi boilers of the Four, Luna, NUVOLA series with a power consumption of 80-135 W.
This is just one of many options to ensure uninterrupted power to the boiler. we individually calculate the optimal options based on your power data and the desired autonomy time. As such, "ready-made" kits do not exist, they are assembled from two main components:

UPS - it is responsible for the quality of processing the incoming voltage (in this case- this is On-Line), for monitoring the presence of voltage and the timeliness of the transition to battery power, for charging the batteries.
Battery pack - it is responsible for the time battery life, the larger the capacity of the batteries in the block, the longer time reserve. The battery life depends on the quality of the batteries themselves.

How many batteries do I need to buy and what capacity? The number of batteries depends on the selected UPS model and is related to the inverter voltage of the specific UPS model. For example, the Inelt Monolith K1000 LT UPS, which has proven itself during the period of "ice rains", 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 to 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 for each manufacturer with the data obtained during the calculation according to the above formula. This is explained by the fact that two reduction factors are taken into account in the formula. This is the efficiency of the converter and the coefficient. discharge depth. Therefore, the estimated time using this formula will be slightly less, than in technical descriptions the UPS itself and is more reliable.

We give the procedure for accurately calculating the autonomy time, for example, for a gas boiler BAXI NUVOLA-3 Comfort 240 i. initial data nameplate electrical power consumption 110 watts, and it is necessary to provide uninterrupted power from the UPS for a period of 12 hours.

According to the formula for calculating the capacity of 110W batteries, we multiply by 12 hours, divide by 8.65 = 152.6 a / h. This is the total battery capacity. T.K. The UPS is powered by two or three 150 batteries, 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 of 50 a / h. There is no 50a/hour, so close to 55a/hour. Battery options in the table below. These are not all options. batteries that we have in stock or available to order. If you go to the battery section, set the desired capacity range, you can choose other options for price and quality.
