Gas heating from bottled gas. Heating a house with gas cylinders - the required gas flow

Paradoxically, but in the modern world there is not yet a central gas pipeline everywhere. And people have to use wood or electricity to heat the premises. But there is another way - heating the house with gas cylinders. This is a good alternative to solid fuel and electric heating in case it is impossible to connect a private dwelling to the central gas pipeline.

Although heating with liquefied hydrocarbon gas propane or propane-butane is somewhat more expensive, in terms of its characteristics, such fuel practically does not differ from gas passing through the main. A gas stove for heating a house from a cylinder is often used in a private house or in a country house, in which the heated area does not exceed 100 sq.m. Consider the main features of balloon heating.

When Is heating with liquefied gas used?

There are no direct prohibitions or restrictive measures for autonomous heating with gas cylinders in a private house. However, heating a home with liquefied gas from a cylinder is not always rational, since obtaining thermal energy in this way requires significant expenses.

Heating a house from a gas cylinder is beneficial only when:

• heated area of ​​premises up to 100 m2;
• organization of good thermal insulation of the dwelling;
• minimizing heat loss.

The arrangement of heating a private house with gas is carried out with conventional 50-liter cylinders of propane or butane, which are compressed to a liquid state.

In summer and winter, different mixtures of combustible substances are used:

• SPBTL (flight combination);
• SPBTZ (winter mix).

In winter, the tanks must be constantly monitored, as interruptions in the supply of fuel are possible due to the difference in the boiling points of the mixture components (propane -40 ° C, butane 0 ° C). As a result, at a temperature of, for example, -10°C, the pressure in the vessel will drop below the level required for the normal functioning of the system. Then the cylinder will have to be heated to at least 0 ° C, so that the butane begins to evaporate.

Attention! Cylinders that are in a private house in conditions of negative temperatures are strictly forbidden to be heated with a heating element or heating cables.

Advantages and disadvantages of balloon heating

Heating a private house with bottled gas has both advantages over other heating options and disadvantages.

First, we give the undeniable advantages of heating with liquefied gas:

• high efficiency at significantly lower labor costs compared to solid fuel heating;
• the ability to convert a gas boiler from a conventional cylinder to main equipment;
• absolute autonomy and independence of the functioning of the balloon system;
• long service life of equipment (15-25 years);
• the presence of demand for cylinders in the secondary market - it is easy to sell containers if they are not needed.

In addition, cylinder heating allows you to heat water in a private house for domestic needs.

We also list the main disadvantages of such a heating system:

• cylinders need to be refilled regularly, approximately every 2-3 weeks, which is inconvenient and costly;
• with improper organization of the system, gas consumption increases significantly;
• the need to create suitable conditions for storing containers.

Thus, the organization of a heating system on cylinders can be very dangerous if some operating conditions of the equipment are not observed. Therefore, vessels can be stored only in a ventilated room, under which there is no basement. It is best to place the cylinders in a separate building.

How to connect the cylinder to the boiler?

To assemble a heating system on gas cylinders, the following equipment is required:

• gas boiler with a special burner for liquefied fuel;
• gas cylinders;
• reducers;
• ramp for connecting several containers;
• stop valves;
• pipes and hoses to connect the system.

As a heat generator, as a rule, a gas boiler with a water circuit is used. Moreover, a special model of the boiler is not required, you can simply replace the burner or nozzles. The power of the heating device is selected in accordance with the area of ​​\u200b\u200bthe room, but the efficiency of the device should be as high as possible. An excellent choice would be a gas condensing boiler.

Attention! Installation of cylinders in the basement or basement is prohibited. It is better to place them in a metal box with holes for ventilation.

Vessels can only be placed in a horizontal position. It is better to place a metal box on the north side of the site in a shaded place.

For the correct and efficient functioning of the boiler, it must be connected to 4-5 cylinders at the same time. To equip the gas pipeline, you will need a tube with a wall thickness of 2 mm or more. At the place of its installation, a sleeve is installed in the wall, the diameter of which is 20-30 mm larger than the cross section of the tube. The space between the sleeve and the pipe is filled with mounting foam.

Cylinders are connected to the system through a reducer, which converts the liquid back into a gaseous state. This can be done in two ways: one reducer for all vessels or one pressure regulator for each cylinder. The execution of the second option provides complete security, although it is more expensive.

In order to increase the interval for refilling containers, it is better to connect several vessels to the boiler at once through a ramp, which separates the cylinders into the main bundle and the spare. First, gas will come from the main group of tanks, and when the fuel runs out, the boiler will switch to a spare bundle. When the main link is updated, the heater will reconnect to the main group.

Attention! Follow the most important safety rule: it is forbidden to fill the cylinder with more than 80% of the volume, since the mixture of propane and butane has a high percentage of expansion, and when the volume is filled more than 85%, the probability of explosion of the vessel is high.

When assembling and installing equipment, pipes and hoses, all connections, connectors and fittings must be checked for gas leakage using ordinary soaping.

Can the cylinder be replaced with a gas tank?

Instead of conventional cylinders of 50 liters, it is allowed to use a more capacious steel container for storing liquefied gas - a gas tank. The volume of some of these tanks is often enough for the entire heating season.

However, heating a home with liquid gas cylinders is considered to be more convenient, since it is much easier to deliver fuel in more compact vessels. In addition, for the gas tank, you need to perform a large amount of work on digging the site, which will result in additional financial investments.

At the same time, the use of a gas tank eliminates the need to simultaneously connect several containers at once, since one cylinder cannot provide sufficient evaporation for the normal operation of the boiler.

Reducer for pressure control

The pressure in the cylinders is constantly changing, and its value depends on many factors:

• number of cylinders;
• composition and temperature of the mixture;
• liquefied gas residue;
• distance of a group of vessels to the boiler.

The reducer is used in order to convert and maintain a stable gas pressure in the vapor state.

It is necessary to select a gearbox for a heating system based on two main characteristics:

• performance;
• operating pressure.

The rationality of heating a private house with gas cylinders depends on the fuel consumption of the boiler. Therefore, the performance of the gearbox should not be less than the injectivity of the heater.

The value of the working pressure of the reducer is also selected in accordance with the characteristics of the boiler equipment. If the pressure that the reducer produces is too high, the operation of the heater will be disrupted. The pressure regulator is made for 20, 30, 37, 42, 50 and 60 mbar.

When connecting vessels using flexible hoses, a reducer with a “herringbone” fitting is required. And when connecting cylinders using combs and rigid pipes, fittings with threaded outlets will be needed.

In addition to the main purpose, devices with automation are equipped with protective elements that are triggered if the pressure rises to a critical level. Then the relief valve opens.

How much fuel is burned?

Heating a house, whose area is approximately 100m 2 with liquefied gas, can be done using a boiler with a capacity of 10 kW. In order to obtain 1 kW of thermal energy, it is necessary to consume 100-120 g / min of liquefied gas at 100% boiler load. If the cold period lasts up to 7 months, then the approximate estimated fuel consumption for the entire season will be about 5 tons.

But in reality, the volume of expenses will be almost 2 times less, thanks to automation, which switches the equipment to economy mode when the air temperature in the premises has reached the set value or guided by the timer settings.

If we compare the costs of heating a summer house or a private house from the main gas pipeline, then heating with liquefied gas is about 5-6 times more expensive. But nevertheless, ultimately cheaper than heating from electricity.

If we take into account the prices of gas in a liquefied state, then heating a country house or summer house with cylinders is not the worst alternative to electric and liquid fuel systems. Especially in cases where there are problems with solid fuel in the region or it is quite expensive.

Heating with liquefied gas is the most rational solution if there are plans to gasify the settlement in the near future, due to the fact that then there is no need to purchase a boiler. In addition, there is an opportunity to practice handling a gas boiler.

How to store gas cylinders in winter?

In the event that the cylinders are located outside the house, then in winter, at a negative temperature, the pressure of liquefied gas drops, and the boiler can simply turn off. In order to avoid this, the cylinders must be installed in a special cabinet that is insulated with non-combustible materials and equipped with good ventilation.

For this purpose, detached non-residential buildings with a minimum level of heating are also well suited. During the operation of the cylinders, the following safety precautions must be observed:

• it is forbidden to warm gas containers with open fire;
• a cellar or basement should not be located near the cylinders, due to the fact that during a leak the liquefied gas goes down, it has no smell and it can accumulate to an explosive concentration;
• installation of a gas leak sensor is highly recommended;
• storage of full cylinders is allowed at a distance of at least 10 meters from the living quarters;
• it is forbidden to store empty cylinders in the house;
• Once every 4 years, cylinders must be checked for tightness and integrity.

Thus, heating a house with gas cylinders is not a profitable way of heating. However, this is an excellent solution as a temporary measure until it is possible to connect to the central gas main.

Summer has come, but the question of how and with what to heat a country house does not lose its relevance.

Regular readers of our site have already managed to get acquainted with the article: "".

Despite the fact that there are many heating systems on the market, many residents would like to heat their home with mains gas.

However, it is not always possible to connect to the “blue fuel” pipeline. If there is no gas and gasification of your individual housing does not shine in the near future, liquefied gas from cylinders will become an alternative.

Is gas-balloon heating profitable?

It seems that autonomous gas heating of a private house is easy and simple to organize. All you need is:

• Buy a gas boiler. Most of the boilers operating on main gas can also operate on liquefied gas. To do this, you need to change the nozzles and, if necessary, reconfigure the control system;
• Purchase a gearbox, gas-cylinder equipment and valves;
• Connect and set up the heating system.

The main questions that arise for any homeowner who is thinking about an LPG heating system are:

• Will I be able to heat the house;
• How long can the boiler work on one cylinder.

Autonomous gas heating of a private house is best organized using 50-liter liquefied gas cylinders.

The practical experience of members of the forum suggests that it is unprofitable to heat a private house with gas from cylinders if the cottage is poorly insulated and the building has large heat losses. It is necessary to take into account the total area of ​​​​a country house. Gas heating from cylinders of a cottage with an area of ​​150-200 sq.m. can cost a pretty penny.

In this case, solid fuel boilers can become an alternative.

- I heard that one 50-liter tank is enough for 1-2 days of work (and this is without taking into account the use of hot water supply).

- I heard that one cylinder with a capacity of 50 liters is enough for 1-2 days of work (and this is without taking into account the use of hot water).

Schweik:

- I heated a house with an area of ​​70 sq.m. with gas. On average (depending on the temperature outside), one 50 l cylinder was enough for me for a period of 1 to 7 days.

Endless:

- I have a well-insulated frame house. I heat about 140 sq.m. At outdoor temperatures down to -20°C, three cylinders are enough for 5-6 days. At -5°C - for 10 days.

- I have a house with an area of ​​145 sq.m, the foundation is UWB, heating with underfloor heating plus hot water supply. The boiler turned on twice a day, for 2-3 hours. Cylinders of 50 l filled with 20 kg. The temperature in the house was set to 23°C. The monthly costs are as follows:

• November - it took 4 cylinders. Temperature outside +5-0°C.
• December - it took 10 pieces. Temperature outside -10 -27°C.
• January - it took 8 pcs. Outdoor temperature -5 - 20°C.
• February - it took 7 pieces. Outdoor temperature -5 -15°C.
• March - it took 6 pcs. Outdoor temperature -5 +5°C.

From 35 to 42 liters of gas is placed in one gas cylinder, in liquid form it is 22 kg. Consumption of liquefied gas for any boiler - 15 liters per day per 100 sq.m. heated area.

Before you understand whether the game is worth the candle and whether autonomous gas heating of a country house will pay off, you need to familiarize yourself with the following data, which presents the economic feasibility of a particular type of heating.

1. \u003d 33 kop / kWh.

2. An electric boiler operating in conjunction with a TA (thermal accumulator) at a night rate = 0.92-1.32 rubles / kWh.

3. Pellet boiler = 1.20 -1.32 rubles / kW * h.

For comparison, the efficiency of heating on liquefied gas is only 2.32 rubles / kWh.

When calculating the efficiency of a particular heating system, it should be taken into account that in the suburbs of Moscow and other regions there may be priorities in choosing fuel, which depend on its availability and climatic conditions. Somewhere it is cheaper to heat the house with coal, and somewhere with firewood.

When calculating the profitability of heating with liquefied gas, many people forget that cylinders will have to be transported to a gas station on average once a week, and these are additional costs, both monetary and temporary. Therefore, heating on liquefied gas can be beneficial if 4 conditions are met:

• Small area of ​​the house - up to 100 sq.m.;
• The house is well insulated;
• In the near future, your village is planned to be gasified, main gas will be connected. In this case, heating with liquefied gas is a temporary measure that allows you not to buy two different boilers;
• The liquefied gas boiler is a backup and works in conjunction with other heating appliances.

evo:

– When I leave for work, I turn off the home gas boiler and turn on the heaters powered by electricity, because. in frosts below -20°C, the gas runs out quickly. In such a “sparing” mode, two cylinders are enough for me for 7 days. And this includes the preparation of hot water. I recommend purchasing at least 3 bottles. One - for the operation of the boiler, one - as a reserve, one - for refueling.

You can also mount a bunch of electric and gas boilers.

Despite the increase in the cost of such a heating system, the overpayment is not for the sake of saving, but to increase comfort.

In this case, the need to travel and refill tanks is partially eliminated.

Features of gas-balloon heating

To install a reliable and safe heating system on liquefied gas, it is necessary to understand its features, which are due to the properties of this fuel.

Cylinders are filled with a mixture of propane and butane. This mixture, at high pressure, is in a liquid state, which is necessary for its transportation. Also, tanks can be filled with different types of fuel - depending on the season:

• technical butane (BT);
• summer technical mixture of propane and butane (SPBTL);
• winter technical mixture of propane and butane (SPBTZ).

Liquefied hydrocarbon gases (propane-butane) are abbreviated as LPG.

Gas-balloon heating requires special attention in winter.

– We decided to heat a house with an area of ​​120 sq.m. using a gas boiler running on liquefied gas. Gas cylinders are on the street in metal cabinets. There is one for the stove, and a bunch of 5 cylinders has been made for the gas boiler, but so far only 2 are connected. When the temperature drops to -2 ° C, a problem arises - gas does not flow, and the boiler, accordingly, does not work. I think the gas is frozen.

Gas neither in pipes, nor in cylinders does not freeze. It simply does not evaporate, and again turns into a liquid inside the gas pipe if it has a negative temperature.

This happens for the following reason. The boiling point of butane is about 0°C. The boiling point of propane is -40°C. At a street temperature of -10 ° C, the propane-butane mixture in the cylinder boils, giving out the gaseous fraction necessary for the operation of the boiler. Propane will evaporate first, and only then the turn will reach butane. During this process, heat is absorbed. The balloon starts to freeze. As a result, the gas remaining in the cylinder (butane) also cools down. This leads to a decrease in the degree of its evaporation. Accordingly, the pressure necessary for the operation of the boiler drops.

There is only one way out - to prevent the cylinder from freezing and warm it to a positive temperature, necessary for the evaporation of butane. You can do this as suggested by a forum member with a nickname Ruslan2.

- In my opinion, the best way to deal with this problem is to force the gas cylinders to be blown with warm air from the room (boiler room) where the boiler is installed: with a fan through an aluminum corrugation or plastic air ducts led into gas boxes, etc.

It is also possible to heat the cylinders (only not with open electrical cables!) According to the principle of a warm water floor, placing them in an insulated gas cabinet.

Safety measures when using gas equipment

A mixture of propane-butane is much heavier than air. Liquefied gas from cylinders always accumulates at the bottom. In the event of a gas leak, if the cylinder is in the room, you can simply not smell it until it reaches an explosive concentration. Therefore, it is planned to install the container outdoors, vertically in an iron box with holes at the bottom and top for ventilation.

gray-haired2:

- I know a case when a man lowered a gas cylinder into the cellar. One day the homeowner decided to pick potatoes. He climbed into the cellar. He did not feel the smell of gas, and since. there was no switch, he just screwed the light bulb into the socket. There was an explosion. The man was lucky, being at the epicenter of the explosion, he escaped with only a shell shock, and a pile of construction debris remained from his garage and two neighboring ones.

Safety rules prohibit: placing gas cylinders in the underground, basements, cellars, pits dug in the yard or near the house.

• It is forbidden to use electric heaters, heating cables, heating elements, etc. for heating gas cylinders.
• Gas cylinders must be placed in special cabinets installed on the north side of the house.

• The cylinder must not be filled more than 80% of its volume. Liquid gas has a large coefficient of volumetric expansion. This means that as the temperature rises, the volume of gas in the vessel increases. The expansion coefficient of the propane-butane mixture is about 7%. According to Russian standards, 15% is left for expansion. A cylinder of any thickness and strength will burst if filled to more than 93% in -20°C frost and brought into a room where +20°C.

• All detachable connections on the gas line must be checked for leakage by washing.
• Detachable connections are made at the points of attachment of various elements where other connections are not possible (faucets, meters, gas appliances, etc.)

• Gas pipelines are made of steel pipes with a wall thickness of at least 2 mm. When passing through the walls, the pipe is placed in a case foamed with a soft material. The connection of the boiler to the gas pipeline can be done with a flexible connection specially designed for this purpose. The reducer is connected to the gas pipeline with a rubber-fabric sleeve (durite hose).

• If the cylinder is located in the room next to the boiler, then the connection is made with a rubber-fabric sleeve.

From our video you can learn how to heat a large house in the absence of main gas.

Natural gas is currently the most optimal fuel for home heating. The only negative is that it is not always possible to connect the heating system to the main gas pipeline. In this case, you can pay attention to an alternative in the form of liquefied gas - boilers using bottled gas in our country are not uncommon.

Classification

Boilers operating on liquefied gas are single-circuit and double-circuit. A single-circuit boiler is intended only for heating, while a double-circuit boiler is capable of both heating the house and providing hot water in it.

Consumers are offered wall-mounted, floor-standing gas boilers with open and closed combustion chambers. In addition, you should pay attention to the power of this heater. A variety of modifications often makes it difficult for the user to choose, so it is worth dwelling in more detail on the most important characteristics.

For boilers operating on liquefied gas, the ability to operate at low pressure is of fundamental importance.

The constant supply of bottled gas will be carried out at a pressure of 3-4 Mbar. Therefore, when choosing a boiler, you should pay attention to this parameter.

efficiency

Efficiency is one of the most important parameters of a heating system. Liquefied gas is more expensive than trunk gas, and transportation costs must be added to its cost.

The efficiency of modern serviceable equipment can reach 90-95%. To calculate the gas consumption for heating, you need to know the total area of ​​\u200b\u200bthe room: approximately 1 kW of power is consumed per 10 sq.m.

For heating and heating water in a country house of 100 sq.m, about 2 cylinders per week and 8-9 cylinders per month will be required. You can connect the cylinders in a group: according to the rules, the use of a system of cylinders up to 15 pcs is allowed. In this case, gas containers must be in a closed metal cabinet.

Mounting equipment

To install the heating system you will need:

• a gas boiler;
• burner for liquefied (balloon) gas and gas cylinders themselves;
• valves and reducers.

Bottled gas burners differ in their configuration from conventional ones, and are usually included as standard with gas boilers. If necessary, they can be purchased separately. Shut-off valves and the necessary gearboxes can be purchased from the company or directly at cylinder filling stations.

Connection

A cylinder or a group of cylinders is connected to the boiler through a reducer with a throughput of about 2 m3 / hour. Reducers for domestic stoves are designed for lower throughput - they are not suitable for the heating system. The gas tank system can have one common reducer or a separate regulator for each cylinder. The second option is more expensive, but it is recommended by the masters - separate gearboxes provide maximum safety.

Cylinders of liquefied gas cannot be installed outdoors: the cold will provoke a decrease in pressure, and the heating pad may refuse to work. The ideal place for installation is a warm, ventilated room. It is important to remember that bottled gas is heavier than air, and in the event of a leak, it will accumulate at the bottom, increasing the likelihood of an explosion. Therefore, the room should be chosen separately from the living rooms. It should not have basements and subfloors!

Gas cylinders are connected to the boiler burner using a metal corrugated pipe - this reduces the likelihood of gas leaks due to system vibrations.

With the help of automatic sensors and the right settings, you can reduce propane consumption rates by 3-4 times. If we are talking about a country house, then gas consumption will be even lower: for the period of absence of people, automation will maintain the temperature at 6-9 ° C, which will reduce propane consumption to 0.7-0.8 cylinders per week. Heating a building with liquefied gas is not the cheapest option, but in some cases it is the most optimal if there is no problem with the delivery of cylinders.

The gas boiler perfectly performs its functions when connected to the main gas pipeline. In this case, it is quite easy to switch the equipment to a constant source of fuel supply - just change the burner.

But if there are no prospects for connecting the building to the gas pipeline, the feasibility of installing a gas boiler should be recalculated. For a house with a total area of ​​​​more than 100 m2 and maintaining a temperature of about 25 ° C, it is worth considering installing a solid fuel boiler or other heat generator and water heating.

Refueling

Cylinders undergo mandatory certification every 3 years - this is necessary for the user's own safety. Such containers can serve for about 10 years. A standard house consumes about 10-12 cylinders per month, so they will have to be refueled weekly - it is impossible to transport more than 3 cylinders at a time without special permission.

Before refueling, the vessels must be prepared. To do this, you need to remove the condensate, which artificially reduces the usable volume and harms the steel walls. Removing condensate is the prerogative of specialists; doing such work with your own hands is always a risk. If for some reason it is difficult to find a master, then you will have to carry out the procedure yourself. The cylinder is taken out to an open space without sources of fire, grounded and then the gearbox is removed. Leave for 2 hours so that the remaining gas disappears. After two hours of inactivity, the vessel turns over, and the water flows into the ground. You can take it to a gas station.

It is worth choosing a refueller who organizes both transportation and a guarantee for work. It is better not to contact car stations, because their equipment does not have a special cut-off valve that regulates the filling of household gas cylinders with gas. They also do not have a special connector for connecting the cylinder to the station equipment.

One of the most popular topics of discussion at various construction forums is heating in a private house with gas cylinders. This raises several important issues related to operation, self-installation and maintenance, as well as security measures.

Is it possible to heat the house with a gas cylinder

Individual gas heating of a private house with cylinders is a good alternative, in the absence of the possibility of connecting to a central highway. The cost of heating from gas is much lower than those that have to be paid for heating with electricity, solid fuel and diesel fuel.

The heat output of the system is enough to warm the house, heat enough water. It is possible to make autonomous gas-balloon heating of a country house or summer house with bottled gas in a simple way.

Cylinders with liquefied gas Propane-Butane

Fundamentally, this scheme is no different from the operation of a gas tank. The propane-butane mixture has a high evaporation rate. The gas evaporating from the surface is suitable for the operation of hot water equipment. For efficient operation, it is necessary to connect gas cylinders to each other in a single fuel supply network to the boiler.

Depending on the season, a summer and winter gas mixture is used. In the first, the ratio of propane and butane is approximately 50 to 50%, the second is 85 to 15%. During the winter season, gas with a high butane ratio freezes, causing the system to shut down.

Cylinders are filled under high pressure, which results in the transformation of the gas into a liquid state. To ensure the reverse process and obtain a gaseous mixture, it is necessary to lower the pressure back. Continuity of gas supply is provided by a special reducer.

The node lowers and stabilizes the pressure. Only a hot water boiler can operate on liquefied gas, with a minimum operating pressure of 3-4 mbar. For convenience, autonomous gas heating of the house operates from a bundle of several cylinders connected to a ramp, which automatically switches the flow rate from the main to the backup fuel source.

The disadvantage of using tanks with liquefied propane gas is the impossibility of heating the entire building. Basically, the systems are used for heating tourist tents, country houses, building change houses, etc.

Do I need a permit for heating from gas cylinders

Gas heating systems from cylinders do not need official registration and registration with the gas service or the fire inspectorate. But, the legislation stipulates the norms and requirements necessary for safe operation, which apply both to the very connection and placement of gas-cylinder installations, and to the room used as a boiler room and LPG storage.

The legality of the use of gas cylinders for heating is stipulated in the Federal Law. Subject to the requirements of fire supervision, autonomous gasification of a private house through gas-balloon installations does not require registration. In practice, this means that the only possible claims may be from the fire inspector. At the next check, he can pay attention to errors, and in case of gross violations, he can seal the installation.

According to it, it is forbidden to install more than one fuel cylinder in the room. The heating system based on several individual cylinder installations must be removed from the residential building.

How to calculate how many bottles of gas you need per month

On average, a cylinder is enough for 3-4 days of work, subject to heating of 100 m². It turns out that for continuous operation of the boiler during the week, it is necessary to empty two containers of 50 liters each. each. Further calculation of gas consumption for heating when using bottled gas is carried out in the following way:

1. With the help of two 50l. cylinders can heat a house of 100 m² for a week.
2. For a month, respectively, about 10 cylinders are needed.

In order to accurately calculate heating using cylinders, it will be necessary to determine the possible heat losses, as well as the additional number of parsing points that will be used in addition to the heating boiler. The approximate consumption of liters of bottled gas per month will be about 500 liters.

The exact number of cylinders required to maintain a comfortable temperature is calculated only after the thermal engineering examination of the building.

What type of balloons to choose?

Since at least 4 cylinders of gas are needed to heat a house, it becomes a difficult task for the consumer: to choose the right container for storing LPG. You can understand the presented assortment if you conditionally classify products into several classes according to the following criteria:

The weak point of all LPG storage tanks is the shut-off valve - the valve. To extend the service life, you will need to put another control valve on the pipeline for each cylinder separately.

How to make gas heating from cylinders yourself

It is better to entrust the installation of autonomous gasification of a private house to specialists, but it is possible to connect the system with your own hands. To do this, you will need to strictly comply with existing fire safety standards and SNiP.

For the correct implementation of the work, several questions will need to be clarified:

1. Where to locate and how to ensure the storage of cylinders.
2. How to properly connect several containers to a single network.
3. Is it possible to heat the cylinder in the winter season.

Where is the LPG equipment located?

Strictly speaking, the placement of gas cylinders in a room is possible only if no more than two containers are connected at the same time (the norms may vary depending on the region). If the number of tanks exceeds the allowable limit, they are installed outdoors in a special cabinet. Additionally, the following rules apply:


Do not store empty containers together with filled ones. Every 4-5 years, the tanks are tested, after which they are again allowed to operate.

How to connect gas cylinders into a single system

The practice of heating from propane cylinders shows that you can significantly reduce costs if you connect not 1-2 containers at the same time, but the whole system. For the installation of gas-balloon heating, the following conditions must be met:


The scheme of the autonomous heating system for a summer house or a country house with gas-balloon equipment with a ramp allows you to simultaneously connect from 1-10 tanks with LPG. The actual need for the number of tanks is calculated from the total heated area.

How to heat a gas cylinder in winter

Heating of cylinders in winter can be done in several ways:

Methods for heating gas cylinders in winter do not allow the use of open flames.

Safety measures for the operation of cylinders

To heat a private house, you need from 4 to 10 cylinders of gas, which in itself is potentially dangerous. For this reason, it is necessary to strictly adhere to the rules of the PB:

• The installation of portable cylinders is carried out strictly according to SNIP. Installation of the gas pipeline and connection to gas consumption points is carried out along the outer walls of the room.
• The room used as a boiler room must have natural and forced ventilation.
• The technical conditions for the installation and connection of Propane-Butane bottled gas for home heating allow installation of 1 LPG tank in residential premises. A system of several cylinders is installed exclusively on the street.
• The warehouse for tanks should not have pits and basements.
• Do not expose the tank to direct sunlight. The cylinder storage cabinet must be waterproof.

The use of liquefied gas in household cylinders for individual heating of residential buildings is allowed by SNiP and PB, but it is best to entrust the installation of the system to professionals. Practice shows that with self-connection it is quite difficult to take into account all existing requirements and ensure safe operation.

In this article we will talk about what you need to know if you decide to heat your home with liquefied gas. Gas (a product of oil refining) is liquefied under the influence of high pressure, and in this state it is supplied to the consumer. This makes it possible to fill the cylinders with a large volume. The cylinder is connected to the heating boiler through a reducer (a device for reducing the pressure in the system). The gas leaving the cylinder passes through the reducer and, as a result of a rapid decrease in pressure, returns to its original (gaseous) state. In the boiler, it is burned, releasing a large amount of heat.

Advantages and disadvantages

Advantages:

• gas is an environmentally friendly product and meets all regulations and standards;
• autonomy, quite simple to connect and operate;
• the pressure in the pipes is relatively stable;
• gas consumption is minimal;
• two times cheaper than diesel fuel.

Disadvantages:

• at a negative temperature, if the cylinder is placed outside, the system may turn off, since the condensate, freezing, prevents the gas from escaping;
• gas cylinders must be kept in a sufficiently warm place.

Fuels and basic rules

Cylinders can be filled with different grades of fuel:

• technical butane- denoted by the abbreviation - B
• a mixture of propane and butane technical summer - SPBTL
• a mixture of propane and butane technical winter - SPBTZ.

Following simple safety rules can save your life.

Heating system

The heating system itself consists of the following elements:

1. Fuel, in our case, liquefied gas.
2. Boiler, one or two circuit, with the transition to liquefied gas.
3. Radiator, heat transfer element.
4. piping system, to distribute heated water to radiators.

Let's take a closer look at the components of the entire system:

With fuel (gas), everything is clear enough, you just need to purchase new ones, quality cylinders, preferably 50 liters, or a gas tank (five cubic meters for storing liquefied gas, approximately 4250 liters). I advise you to purchase in a specialized store.

To calculate the gas consumed by the system, you need to know:

• room area, which you are going to heat;
• boiler power and coefficient of performance (COP).

Calculation of the cost of balloon heating

The heating season is approximately 6-7 months, multiply by 30 days and multiply by 24 hours, then multiply by 0.5 (the coefficient for calculating the time the gas burner in the boiler operates at maximum power, we take about 50% of the total time of the entire system) = 2520 hours.

To heat up 100 sq. m. premises, you will need a boiler with a capacity of approximately 10 kW.

Calculation of gas fuel consumption, which will be required for heating the house: 10 kW. hours * 2520 hours \u003d 25,200 kW. h.

For a boiler with a power of 10 kW. and, with an efficiency of at least 90%, the fuel consumption (liquefied gas) is 0.86 kg/h:

• calculation of gas consumption for heating a house will look like this: 0.86 kg / h * 2520 h = 2167.2 kg / year;
• in a container for 27 liters of liquefied gas in total 11.5 kilograms;
• the average cost of a liter of gas is approximately 14 rubles;

We calculate the cost of the required amount of liquefied gas for the heating season: (2167.2 kg. / Year * 27 liters / 11.5 kg.) * 14 rubles. = 71 860 rubles per year.

If containers (bolons) of 50 liters are used. in which approximately 21.2 kg., liquid gas is filled: (2167.2 kg / year. * 50 l. / 21.2 kg.) * 14 rubles. = 71,558 rubles per year.

Of course example calculation, for a more accurate calculation, much more values ​​\u200b\u200bare required (location of the house, area, degree of thermal insulation of the house, windows, doors, and a number of other factors that can affect the consumption of heat energy).

In principle, there is nothing complicated in choosing a boiler, its power is calculated based on the area of ​​\u200b\u200bthe room, for example, a boiler with a capacity of 10kw., suits the room in 100 sq.m. The main thing is that the boiler should be a good, well-known company specializing in this equipment. And a wide range of spare parts were on sale for it (there is nothing eternal). You can put double boiler, and it will provide you not only with heat in the house, but also with hot water, but at the same time the gas consumption will increase (depending on what the hot water consumption will be). And if you have a two or three-story house, then the boiler should take a little more power. So it will last much longer.

Specialists perform much more accurate calculations to calculate the thermal energy of heating radiators in terms of power. Very important heating area calculation radiators, for their correct distribution.

When buying radiators, you will definitely need the simplest calculation of heating power. In order to do this, it is necessary to calculate the area of ​​the room and its height, as well as the cost of thermal energy (power) per 1 m. Under standard conditions, for a typical room, approximately 41 W. power. And multiplying the volume of the room (room) by this indicator, we get the amount of heat that is necessary to provide the radiator when heating the room (room). For example, to heat one room with a total area 18 sq.m. and height 3m. you need a radiator, with an ordinal power at 2.5 kW.

Now you need to calculate the number of radiators for heating the room. We divide the power necessary for heating the room by the power of one section of the battery, then we can get the required number of radiator sections. If my memory serves me right, then one section of a bimetallic heating radiator has a power of approximately 150 watts. Before buying a radiator battery, on the package, or in his passport, it is reported its thermal power. This is not a complex concept that refers to the heat (in quantitative terms) that the battery will release when cooled from the operating temperature of the heating, to a temperature of about 18-20 degrees Celsius.

Calculation of radiators and their number by specialists

Of course, the most correct way is to apply for the calculation to specialists. Their method is quite accurate and allows you to calculate the required number of radiator sections for each room in a residential building, and for any other room in a private house. Their method takes into account many parameters:

• material, what the walls are made of and their thickness
• window type, installed in every room of the house
• area ratio walls and windows
• climatic conditions in your area
• is the room above your room heated
• how many walls your room goes outside the house
• area rooms and ceiling heights.

Piping system

The system itself consists of properly selected and laid pipes of heating mains, which connect your radiators and the boiler. There are two types of such systems for laying pipelines: one-pipe and two-pipe.

When a heating system is being designed, a two-pipe connection scheme involves the installation of two pipes on each of the batteries, the so-called "supply and return". Through one of them (supply), the coolant (water) enters the heater, through the other (return), having already cooled down, it returns to the boiler. The use of such a wiring diagram makes it possible to achieve the same degree of heating coolant in all batteries at home. Two-pipe type wiring is divided into two main varieties:

1. Connection of radiators in parallel-series (one closed ring).
2. Using a collector, to which all radiators are connected with separate sleeves (pipes).

The second type of connection of radiators makes it possible regulate the temperature each battery. But she also has a tangible financial disadvantage, this is the need to install a large number of metal-plastic or other pipes for heating for supplying to radiators. A single-pipe heating scheme made of metal-plastic pipes functions as follows: the heated coolant (water) simply flows through the pipes from one radiator to another. Simply put, such a system is consistent, and this leads to a gradual coolant cooling along his path. This means that the last radiator in the chain will always be significantly colder than the first battery. The main advantage of a single-pipe heating heating system made of metal-plastic pipes is it's cheap her arrangement.

Also, very important is degree of thermal insulation your house. If you have taken all measures and insulated the walls, ceilings, floors, installed good new windows, and you have a modern, high-quality, front door (doors). Then the heat loss of your heating system will be minimal and for the season, you will spend much less money than planned.
