Gas boilers for liquefied gas industrial. How to choose a gas boiler for liquefied gas. Where to buy wall-mounted heating boilers
The low quality of electricity supplied to most places where gas boilers are installed, does not allow full use of the functions the latter.
This leads to quick and serious breakdowns, and also significantly reduces the service life of products.
For this case, provided stabilizer use, which controls the frequency and current strength, thereby acting as a "power supply" for the entire gas system.
The main characteristics of wall and floor gas boilers
Choosing the right gas boiler for autonomous heating system necessary take into account certain features of this device so that the selected unit works not only for a long time, but also as efficiently as possible.
Among the most significant features gas boilers include the following:
- Power
The ability of the boiler to withstand this or that load depends on it. The power of heating equipment always means the volume of premises that can be heated with its help under certain external climatic conditions. It is very easy to calculate the power sufficient to heat a particular house. It is necessary to be mindful of what for heating 1 sq. m premises with a ceiling height of not more than 3 m enough 100 W boiler power.
- Number of circuits
Gas boilers may have one or two circuits. In the first case, the device is used exclusively for heating the coolant, which will circulate in the heating system. In the second case, one of the circuits heats the coolant, and the other - water for the water supply system.
Dual circuit boilers can immediately supply heated running water to the system or are equipped with a boiler for heating water. single circuit devices are used mainly in cases where the house where they are installed will not be residential.
Flow boilers they quickly heat water only with a small water intake from the system, they are compact, but at the same time they can heat the water unevenly. Boilers with boilers they evenly heat the water and store its supply equal to the volume of the boiler, but at the same time they are rather bulky, they are difficult to maintain / repair.
- Type of control and number of available options
Most modern gas boilers equipped with an electronic control system for optimum performance of the device.
Some functions of the devices allow not only to use them more efficiently, but also to reduce fuel consumption.
For example, automatic control of the boiler power depending on the ambient temperature, the ability to program the device depending on the day of the week, time of day, etc.
- Mounting method
Gas boilers can be installed on the wall or on the floor. The first type is ideal for space heating up to 350 sq. m. Such boilers are equipped with everything necessary for autonomous operation. Floor units are mostly designed for heating industrial premises, since their starting power is 32 kW. Similar gas appliances most often they are single-circuit atmospheric.

Liquefied gas (balloon) boiler: selection criteria and principle of operation
5 (100%) votes: 2Now we will look at the criteria for choosing a liquefied gas boiler (balloon boiler), we will figure out how to calculate consumption and consumption, as well as which manufacturers offer such equipment.
Gas boilers for bottled gas (or heating boilers for liquefied gas) are now very popular. Homeowners often prefer heating with this option. After all, it is practical and less expensive.
The present gas heating on bottled gas involves the use of a whole range of equipment, which consists of a heat supply system and several types of equipment. However, the main unit is still a boiler.
As in conventional heating systems, bottled gas boilers make it possible to equip heat and hot water living quarters, since it is possible to combine these two functions.
LPG gas boiler
The principle of operation of the boiler
The gas boiler for liquefied gas according to the principle of operation and design is a standard gas heat generator. In it, due to the combustion of fuel, heat is released, which heats the heat exchanger. The coolant "absorbs" and transfers heat energy along the contours of the heating system.
The principle of operation of the boiler on liquefied gas
Often, heating equipment operating on bottled gas is characterized by a universal size, high performance efficiency(up to 95%), productivity. In addition, such devices do not require a lot of money, they can boast of efficiency, which will save the owner's budget for fuel.
Unlike fuel units that run on natural gas, bottled gas boilers can operate at a reduced pressure of the supplied fuel.
The consumption of liquefied gas for heating a house of 100 m² is approximately 561 liters per month.
To heat Vacation home bottled gas, as well as to provide it with hot water to the full, it will take no more than 3-4 mbar. When working on the main gas, these figures should be much higher.
Also, a gas boiler from a cylinder can be easily switched to a different mode of operation, namely using, for example, main gas. In this case, nozzles and other equipment elements are simply replaced. As you can see, buying such a boiler saves money, as it turns out that you are buying not one boiler, but two at once (two in one)!
LPG consumption
The price is the most important point in the selection of fuel for the boiler. After all, you have to pay year after year. Plus the amount of construction of structures (pipes, external networks; insulation of ceilings, walls, floors, triple glazing, etc.), which are needed to maintain a normal temperature ...
How much you can save on this, you can calculate when examining official documents. In the Russian market since 2000, in houses, according to SNiP, the thickness of the outer walls has been increased from 65 cm to 77 cm.
The consumption of liquefied gas for heating a house of 200 m² will be 1122 liters.
In the following table, you can see the required amount of fuel and the cost of it, calculate the costs for the year. It indicates the approximate ratio of costs for common types of fuel. The standard for heat consumption is 0.24 Gcal/sq.m. per year or 0.02 Gcal/sq.m. per month.
Fuel | Heat of combustion, Gcal | unit of measurement | Average price, thousand rubles | Boiler efficiency, % |
---|---|---|---|---|
Diesel fuel | 7,5 | you SL. | 32 | 90 |
Electricity | — | kWh | 0,002 — 0,004 | 98 |
Gas in bottles | 10,8 | t | 23 — 25 | 92 |
Coal | 5,8 – 6,4 | t | 4,0 — 5,0 | 60 |
Peat | 2,9 | t | 1,3 — 1,6 | 60 |
Natural gas | 7,9 | thousand m³ | 4,0 — 5,0 | 92 |
The consumption of liquefied gas for heating a house of 100 m² is about 1.2 kg / h (with a boiler power of about 10 kW).
A gas boiler for giving from a cylinder is an uncontested option that allows you to provide comfortable living conditions. Especially if the dacha is mainly used only in summer and is small in area. It is also suitable for baths.
If the frost is not severe, then a cylinder of 40 liters is enough to heat a house of 50 m² for three days.
Overview of import and Russian manufacturers of propane boilers
To begin with, let's make a reservation that before buying it is worth learning about the parameters ( technical specifications), according to which boilers of this type are usually chosen.
- Power. It depends on it whether the equipment will heat the entire area of the building and whether it will provide hot water in the required volume.
- Boiler type. According to the method of installation, wall and floor boilers are distinguished, according to the type of combustion chamber - open and closed, if possible, providing hot water - single-circuit and double-circuit.
- Gas pressure. The passport of the heating unit must indicate the minimum value of gas pressure in the range of 3-4 mbar. After all, the lower the indicator, the greater the volume of gas from the cylinders will be emitted.
- Gas consumption. To generate 1 kW of heat, a cylinder boiler consumes about 0.12 kg / h. It turns out that for heat generator with a power of 15 kW, fuel consumption will be about 1.7 kg / h. These figures are conditional, because the intensity of consumption of liquefied gas depends on many nuances (equipment efficiency, power, automation level, external air, required temperature in the house, building heat loss, need for hot water supply).
- efficiency. The operation of the equipment will be more economical and efficient if efficiency will be higher. On the market, you can choose gas boilers with an efficiency of 90 to 94%.
Before buying boilers running on liquefied gas, they carry out calculations that show the profitability of the installation, as well as the features of maintenance and operation of the heating system.
The average monthly consumption of liquefied gas for heating a house of 150 m² is about 841.5 liters per month.
Boilers operating on liquefied gas, Russian-made and foreign, differ in price. Many companies offer heating devices that can be switched to work on liquefied gas.
Brands of gas heating boilers:
- Italian brand "Baxi";
- Protherm (Slovakia);
- Zhukovsky Machine-Building Plant (ZHMZ) produces two types of gas boilers - AKGV and AOGV;

Today, autonomous heating systems are in demand among owners of private households. The source of heat for them is often liquefied gas for home heating. The type of "autonomy" with the use of a gas boiler on liquefied gas, the consumption of which is minimal, is the most popular.
Often, property owners refuse fuel from the main gas pipeline in favor of another option that provides for heating country house liquefied gas, which is convenient to use and has an affordable price.
LPG boilers
Modern gas heating on liquefied gas involves the use of a whole complex consisting of several types of equipment and a heat supply system. But the main unit still remains the boiler, which provides heat from the fuel.As in traditional heating structures, a liquefied gas boiler for private buildings allows, through its combustion, to provide heating for residential premises and hot water supply, since a combination of these two functions is possible.
Often, heating equipment that runs on liquefied gas is compact in size, performance and high efficiency, sometimes reaching 95%. In addition, a liquefied gas heating boiler (see photo) has a low cost and, together with efficiency, can significantly reduce the costs associated with the purchase of fuel.
In addition to all the advantages described earlier in the article, this type of fuel units differs from natural gas devices in that they can operate at low fuel supply pressure. In order to fully satisfy the needs of the residents of a large house for heating and hot water, it is enough to have a pressure in the system equal to only 3-4 mbar, while when working on main gas, this figure should be much higher.
Even in the presence of low pressure in the structure, heating on liquefied gas has a negligible fuel consumption. This allows you to save a considerable amount of money from the family budget. At the same time, liquefied gas for heating will be used as efficiently as possible.
Owners of private households should be aware that liquefied gas heating boilers can be easily transferred to a different mode of operation - using a different type of fuel, or rather main gas. For this purpose, not only nozzles are replaced, but also other elements of equipment. Thus, it turns out that the buyer purchases two boilers in one and saves a lot of money and time.
Range of boilers in the domestic market
The choice of heating units operating on liquefied gas in the domestic market is simply huge. It also has products from various global manufacturers.Each model has unique performance characteristics and, accordingly, cost. In order for the heating of a country cottage or cottage with liquefied gas from a gas tank to be economical and efficient, it is necessary to choose the right type of heating unit and take into account all the features of operation.
When buying a device, consider:
- boiler type;
- efficiency;
- which company is made.
efficiency. We can say that all units operating on liquefied gas are characterized by high efficiency rates (90-94%). Therefore, they are installed in houses, suburban buildings or in other buildings. As a result, the higher this indicator for the equipment, the more economically and rationally the fuel is used.
Power. It is one of the main parameters for this type of heating equipment. To determine what kind of fuel consumption, power and performance a gas boiler has for liquefied gas, you need to read the instructions for a specific model of the device (read also: ""). It is necessary that the selected unit without problems provides hot water and heat to all rooms in the house at no extra cost.
Manufacturing company. As practice has proven, it is desirable to give preference to companies that have been proven over a long period of time, whose products are of the appropriate quality standards, reliability, and long service life.
Calculation of the power of gas boilers on liquefied gas: fuel consumption
Only employees of companies professionally engaged in the supply and installation of such heating units can make accurate calculations of the power of heating equipment operating on liquefied gas. To do this, they will need to provide all the data about the room in which it is planned to mount it. Also, when carrying out calculations, the characteristics of the model are taken into account and it is determined what kind of gas boiler the consumption of liquefied gas has.Such calculations are not cheap pleasure, so many consumers are limited to approximate calculations performed on their own. For this, it is considered that 1 kW of thermal energy is required for 10 "squares" of the area of \u200b\u200bthe room to provide heating, despite the fact that the height of the ceilings does not exceed three meters. Given definitions required power not very accurate, but it will help to choose heating equipment.
If it is necessary to accurately select the unit, it is necessary to take into account a large number of parameters and factors, including the volume of the room, the presence / absence of additional insulation, the size and number of windows and doors, etc.
Experts do not recommend choosing cheap options for heating devices, since they do not differ in quality and high rates of efficiency and reliability in operation. The best choice are expensive liquefied gas boilers in which fuel consumption is minimal even when heating large rooms.
The propane-butane mixture, which is the main source of energy in autonomous gas supply systems, is an economical and inexpensive fuel, and therefore it is not advisable to save on a boiler.
Starting a gas boiler on liquefied gas, video:
Gas heating boilers occupy a leading position in the consumer market, and this is not surprising, because a domestic hot water boiler operating on liquefied gas has a compact size, various installation options, ease of maintenance and operation, and an attractive price. From year to year, Moscow is being built up with new buildings that require new heating systems, and our online store has in its assortment gas heating boilers of different capacities that meet different needs - they provide autonomous heating hot water and the heating process of your premises with the onset of cold weather.
Despite the fact that the use of a gas boiler implies the presence of a chimney, it is very democratic in maintenance - the price of fuel is quite low. Buy gas bottle for cooking or for refueling the heating boiler is not difficult.
Gas heating boilers - what are the pros
Gas heating boilers have a lot of advantages, after studying which, you want to buy such a device without delay. As mentioned above, the price of this type of fuel is quite low, so the heating season will not be a serious test for your wallet, and the presence of heat in the house and hot water in the bathroom will make your home comfortable and cozy.
Gas heating boilers, the price of which is quite attractive even if you choose to buy a store in the center of Moscow, are equipped with a serious protection system that can prevent an accident. The heating boiler has automated system maintaining combustion - air and fuel are supplied without any human intervention and control.
And if you have chosen a domestic liquefied gas heating boiler with the ability to connect to climate control devices, then “smart” modern equipment will be able to automatically select the operating mode. You can leave your country house equipped with a gas boiler for a long time without fear that trouble will happen. Moreover, it should be noted that the price of such boilers practically does not change from the presence of a protection system. Almost all gas boilers are equipped with a gas pressure control that stops the appliance when the pressure drops or after a sudden cut in the fuel supply, as well as a flame control that stops the gas supply if the flame goes out. You can also buy a gas-fired home boiler with superheat control, which will instantly stop the equipment if the circulation of the coolant stops or leaks. Thus, you will avoid a fire or breakdown of the boiler itself.
The gas boiler allows you to adjust the intensity of combustion, which means that hot air is supplied evenly and the temperature in the living quarters always meets your expectations. In addition, such boilers are the most environmentally friendly, because the emission of harmful gases during operation is minimal, and Moscow really appreciates equipment that does not harm environment and atmosphere.
Gas heating boilers - pitfalls
Boilers operating on liquefied gas also have several so-called disadvantages. First of all, it is energy dependence - after all, gas heating boilers are mostly equipped with microprocessor control, a fan and an air supply valve servo drive. All these components are electrified and are responsible for the efficiency of the device.
Gas boilers with closed combustion chambers are also equipped with an electric fan, because they work on the principle of forced removal of flue gases. Due to the operation of fans and constant air circulation, a gas boiler for heating a house is quite noisy, although it does not exceed the established noise standards. If you want to avoid noise as much as possible, choose models with noise reduction, although keep in mind that you will not be able to avoid noise 100 percent.
Also, all gas boilers have electric ignition. Please note that until now the Internet offers fully volatile boilers, their price is somewhat lower, and their operation is “lame” in comparison with others.
Heating boilers operating on liquefied gas, require strict adherence to safety rules during installation and operation - after all, an explosive substance is used for space heating, therefore, professionals should be trusted in installing and connecting equipment.
Gas heating boiler - the hot heart of your home
The above pros and cons of using a gas boiler will make it possible to draw a very unambiguous conclusion - heating a room using boilers of this type ideally meets the price-quality ratio. You pay a very affordable price for a complete set of equipment, but you get the opportunity to carefully regulate the air temperature in your home.
When buying a gas heating boiler with an open or closed combustion chamber (in the open version it is a classic floor-standing boiler with a cast-iron heat exchanger and with a conventional chimney, in the closed version it is a wall-mounted boiler with a copper heat exchanger and a coaxial chimney, which is a pipe in a pipe), you provide for your home warmth for many years. The gas boiler is easy to operate and maintain and works automatically without the constant intervention of specialists or the owner.
Heating a private house with liquefied gas
Choosing a liquefied gas boiler
An important criterion is power, measured in kW. The heated area, as a rule, is 9-10 times larger than this value. That is, choosing a boiler with a capacity of 11.3 kW, you will heat a room with an area of about 100 m 2.
However, it is necessary to make an allowance for the fact that during prolonged and severe frosts, equipment of such power will not be able to maintain the set temperature. Therefore, experts recommend choosing a boiler unit with a margin.
Other options:
- Boiler type. According to the method of installation, wall and floor models are distinguished, according to functionality - single- and double-circuit (heat + hot water), with an open or closed combustion chamber.
- efficiency. The higher the indicator, the more economical and efficient the installation will be. The parameter varies in the range of 90-94%.
- Pressure . An LPG unit must operate at low pressure (3-5 mbar). A low value will ensure that gas from the cylinders is produced without residue.
- Gas consumption . The figures indicated by the manufacturer are conditional and depend on the power and efficiency of the unit, the set temperature in the room and outside the window, the heat loss of the building and other factors.
When planning the construction of a house, the design of the heating system also needs to be given attention.
The right decision is to delegate the task to experienced designers who:
- calculate the amount of heat load;
- develop recommendations regarding the choice of heating equipment and related materials.
Knowing the desired parameters of the boiler, it remains to select the device according to appearance and price. Russian boilers are the cheapest. Popular Japanese-made models are twice as expensive. And the "Germans" will cost even more.
LPG boilerPrinciple of operation
Comparing conventional gas boilers and liquefied gas heating boilers, the following differences in the principle of operation can be distinguished:
- Less pressure is required for normal operation. The gas-air mixture is supplied under pressure not exceeding 3-4 mbar. The main gas is supplied under a pressure of 0.8-1 bar.
- Converting liquid fuel into gaseous. The propane-butane mixture is transported as a liquid. It turns into a gas under certain conditions. Constant pressure in the pipeline is one of them. Creation necessary conditions, ensuring stable operation is the task of a gearbox mounted between the boiler unit and the fuel tank.
- efficiency. Heating boilers on liquefied gas operate with an efficiency of 92-95%.
- Nozzles. They have a different (smaller) outlet diameter. This ensures a low feed rate of the gas-air mixture, approximately 0.86 kg/h.
The principle of operation of boilers on liquefied gas
Operation features
Choosing a boiler that runs on liquefied fuel, remember to follow the rules for the operation of these installations:
- It is prohibited to equip boiler rooms in basement or semi-basement premises. Propane-butane mixture is flammable. When mixed with air, it becomes explosive. And since the gas is heavier than air, in the event of a leak, it does not erode through the windows and ventilation, accumulating on the floor.
- If there is an underground storage for cylinders or a gas tank, it should be located no closer than 10 meters from the house.
- When equipping a storage facility in the depth of the site, there will be a problem with the passage of a tanker to it. There is also a huge list of requirements that must be met. In this regard, the design and installation should be carried out by a specialized organization.
- It is necessary to have an agreement for Maintenance installation.
- A double-circuit liquefied gas boiler costs much more than a single-circuit one. It is recommended to use the second option complete with a geyser. So you will save money and will not be left without hot water in the event of a breakdown of the boiler unit.
Outdoor installation of propane tanks
The situation with the lack of energy
When choosing heating equipment, you should take care of the possibility of using other types of fuel.
Main reasons:
- To heat a house of 100 m 2 with a boiler with an efficiency of 92%, 18 liters of liquefied gas per day will be needed, i.e. one bottle of 50 liters is enough for 2.5 days. To ensure uninterrupted operation, 3 main tanks and 3 spare tanks are required.
- Replacing cylinders involves paying the costs of transporting and filling them.
- Frequent change of cylinders entails the risk of negligence in this procedure. As a result, leakage, ignition, explosion may occur.
- The equipment of a gas tank involves compliance with a large list of requirements, preparation of design documentation and obtaining permits.
Location of the gas tank for supplying liquefied gas
Small area buildings
Cases when a boiler is the best option and the search for alternative heat sources is not important:
- Building area up to 50 m 2 .
- In the absence of people in the room, the temperature is maintained at 5-10 degrees.
- The operation of the boiler at full capacity is needed periodically.
Benefits of choosing:
- There is no need to prepare project documentation and obtain permits.
- It is permissible to install a low-power boiler unit of any type (wall-mounted, floor-standing). It is important to be able to switch to liquefied gas. There are no devices designed to run exclusively on propane. All models of equipment on the market can operate on natural gas and liquefied propane.
Advice! Select an anti-freeze fluid to fill the system to avoid an accident.
How to convert a heating boiler to liquefied gas
Tasks to be solved:
- Changing the rate of supply of the fuel mixture.
- Replacing nozzles by installing special jets.
- Changing operating parameters, setting automation for them.
Most models of modern single- and double-circuit boilers are designed to operate both on main gas and on liquefied fuel. It is enough to replace the nozzles and select a different operating mode.
Converting the boiler to liquefied gas fuelWhen heater not designed to operate on liquefied gas, transferring the boiler to this species fuel is somewhat more difficult. It is necessary to carry out work on the reconfiguration of control valves and automation.
It is important that all reconfiguration of the equipment is performed by a licensed specialist!
What is the consumption of liquefied gas at the boiler
You can find this information by reading technical documentation. Each model consumption is different, as it depends on a number of factors:
- Burner type.
- Selected settings.
- Performance.
On average, to provide a boiler with a capacity of 10-15 kW, 2 cylinders of fuel will be needed. Thus, it is more profitable to use main gas.
Heating system on liquefied gas based on the area of the house
Switching the boiler to liquefied gas is only necessary in a number of cases:
- Temporary transfer. Registration of a new boiler, preparation of project documentation, connection of the installation to the main - operations that can take half a year. During this period, it is economically advantageous to use the already purchased boiler in a different mode of operation.
- Use of a gas tank. This technique is more cost-effective than using firewood, diesel fuel or electricity for space heating. Important nuance: Incorrect setting results in a 15% increase in fuel consumption. You need to seek help from a qualified professional.
Therefore
It is advisable to use gas boilers for heating a private house that can run on liquefied fuel for the following reasons:
- Economic component.
- High operating safety.
- The ability to transfer equipment to a particular mode of operation.
At the same time, the operation of the boiler in this mode does not differ in comfort, as it involves constant material costs for refueling cylinders, and the expenditure of physical strength and time for connecting containers.
For heating an apartment, it is more profitable to use a conventional wall-mounted boiler connected to the central highway.
