How a gas boiler using bottled gas works, features of operation. Subtleties of organizing home heating with gas cylinders: rules for storing fuel, choosing a boiler and reviews from owners Heating a private house with cylinder gas consumption

One of the most popular topics of discussion on various construction forums is heating in a private house with gas cylinders. In this regard, there are several important issues related to the operation, self-installation and maintenance, as well as safety measures.

Is it possible to heat a house with a gas cylinder?

Individual gas heating in a private house with cylinders is a good alternative if there is no possibility of connecting to the central highway. The costs of heating with gas are much lower than what you have to pay when heating with electricity, solid and diesel fuel.

The heat output of the system is enough to warm up the house and heat a sufficient amount of water. It is possible to make autonomous gas heating country house or giving 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 operating water heating equipment. For efficient work it is necessary to connect the gas cylinders together into a single fuel supply network to the boiler.

Depending on the time of year, summer and winter are used gas mixture. In the first, the ratio of propane and butane is approximately 50 to 50%, the second is 85 to 15%. IN winter time years, gas with a high butane ratio freezes, causing the system to stop operating.

Cylinders are filled under high pressure, which leads to 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 ensured by a special reducer.

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

The disadvantage of using tanks with liquefied propane gas is the inability to heat the entire building. The systems are mainly used for heating tourist tents, country houses, construction cabins, etc.

Do I need a permit for heating from gas cylinders?

Gas heating systems from cylinders do not require official registration and registration with the gas service or fire inspection. But the legislation stipulates the norms and requirements necessary for safe operation, both for the connection and placement of gas cylinder installations, and for the premises used as a boiler room and LPG warehouse.

The legality of using gas cylinders for heating is stipulated in the Federal Law. Subject to compliance with fire safety requirements, autonomous gasification of a private home using gas cylinder installations does not require registration. In practice, this means that the only possible claims may be from the fire inspector. During the next inspection, he may draw attention to errors, and in case of gross violations, he may seal the installation.

According to this, it is prohibited to install more than one fuel cylinder in a room. A heating system based on several individual cylinder units must be removed from the residential building.

How to calculate how many gas cylinders you need per month

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

Using two 50l. cylinders can heat a house of 100 m² for a week.
For a month, accordingly, about 10 cylinders are needed.

In order to accurately calculate heating using cylinders, you will need to determine the possible heat loss, as well as the additional number of distribution 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 a thermal engineering examination of the building.

What type of cylinders should I choose?

Since at least 4 cylinders of gas are needed to heat a house, the consumer faces not an easy task: choose the right container for storing LPG. You can understand the presented assortment if you conditionally classify the 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 install 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 to a private house to specialists, but it is possible to connect the system yourself. This will require strict adherence to existing regulations. fire safety and SNiP.

To carry out the work correctly, you will need to clarify several questions:

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

Where is gas equipment located?

Strictly speaking, placing gas cylinders indoors is possible only if no more than two containers are connected simultaneously (standards may vary depending on the region). If the number of tanks exceeds the permissible limit, they are installed outdoors in a special cabinet. Additionally, the following rules apply:

It is prohibited to store empty containers together with filled ones. Every 4-5 years, the tanks are tested, after which they are allowed into operation again.

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. To install gas cylinder heating, you will need to perform following conditions:

System diagram autonomous heating cottage or country house with gas equipment with a ramp, allows you to simultaneously connect from 1-10 LPG containers. The actual need for the number of tanks is calculated based on 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 fire.

Safety precautions when using cylinders

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

Installation of portable cylinders is carried out strictly in accordance with SNIP. Installation of the gas pipeline and connection to gas consumption points is carried out along the external walls of the room.
The room used as a boiler room must have natural and forced ventilation.
The technical conditions for installing and connecting bottled Propane-Butane gas for heating a house allow for the installation of 1 LPG tank in residential premises. A system of several cylinders is installed exclusively on the street.
The warehouse for containers should not have pits and basements.
Direct hits are not allowed sun rays to the tank. The cabinet for storing cylinders must be waterproof.

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

Dacha... Some people associate this word with physical work, others with relaxation and a wonderful place to spend time. But in any case, before the owners country building sooner or later a solution to the problem arises regarding the creation of comfortable climatic conditions during the cold season. Stoves are increasingly remaining in the last century, but heating the dacha gas cylinder, boiler or convector are becoming more and more popular.

Gas is a powerful energy carrier that has been and remains the most relevant and efficient energy resource.

When installing gas heating in a dacha, you can use:

boiler;
cylinders;
convectors.

A gas boiler

The laid gas line allows you to create a heating system using a boiler. In this case, it is important to determine the power of the unit itself. Approximately 1.7 kW of power is needed to heat 1 sq. m of room (this is with a reserve). With a dacha area of 30 sq. m can be handled by a 51 kW gas boiler.

Rice. 1

Boilers are available as floor-mounted or wall-mounted. Floor-mounted ones are more suitable for large dachas with frequent visitors; they do not depend on electricity, but they take up a lot of territory and require additional equipment. Wall-mounted units are compact, easy to use, almost all models are dual-circuit (they heat household water in parallel), but have low durability.

Gas heating of a dacha using a boiler requires the construction of a boiler room (Fig. 1). It is not necessary to erect a separate building for this; you can also use part of some room in the dacha.

For autonomous heating of a dacha you will need:

pipes for coolant;
radiators;
chimney;
pump for water circulation and others.

Advantages of this heating system:

autonomous operation;
easy to use;
saving;
stable fuel pressure.

Gas cylinders in the country and boiler

Many areas, including country houses, are far from gas mains. Gas cylinders are good option to create a heating system in the house.

The whole system is quite complex and includes:

boiler;
cylinders;
reduced gas burner;
pipeline fittings;
gas pipeline

The choice of boiler is carried out in the same way as in the case of a gas main.

But there are three important differences in choosing a boiler:

replacing the “original” burner with one that runs on reduced cylinder gas;
choose a unit with low pressure to obtain high use of gas from cylinders;
the highest possible efficiency (in the case of using a highway, it is not so important).

It is advisable to attach several cylinders to the boiler in order to “mess around” with them less often. Gas heating with cylinders in the country requires special safety measures: it is important to install them in some warm building, but not in the basement. If you install cylinders outside, the fuel pressure will decrease, which will lead to the boiler burner turning off. And if you carry out installation in the basement or nearby living rooms, then the dangers lie in possible fuel leaks and consequences.

Rice. 2

Storage of gas cylinders at the dacha should be carried out in a separate room (Fig. 2), where there is and ventilation system, and a flat concrete floor.

For approximately 1 month of heating a dacha, you will need 2 cylinders per area of 50 square meters. m., and for 100 sq. m – 3 cylinders.

Gas convectors in the country

Gas convectors have a number of advantages over other heating devices (boiler, wiring, pump).

Advantages:

saving energy resources;
no additional equipment;
simple installation;
does not require electricity;
does not burn oxygen.

The equipment operates automatically, adhering to the set heat temperature. This method heating requires only monitoring and replacement of gas cylinders.

The metal heat exchanger of the structure contains a chamber in which reduced fuel is burned. chimney combustion products are discharged outside. These devices are often equipped with fans, which help to quickly heat the rooms. The gas convector (Figure 3) can operate from a gas main or from reduced gas cylinders. The convector saves 50% of energy, unlike others similar systems heating.

Rice. 3

Convectors do an excellent job of heating a small area; each individual room requires the installation of a unit, which is not entirely economical in terms of installation. Among heaters for temporary housing, convectors remain leaders due to their safety, efficiency and low price.

Heating for a dacha without gas is possible using solid fuel boilers, stoves, electricity, solar and wind energy, as well as geothermal heating. The choice is quite wide, so everyone has the opportunity to choose the best option for their capabilities and needs.

Heating a house with gas cylinders is indispensable for use if there is no connection to the central gas main. This is a common type today autonomous system heating country houses, private dachas. Before installing a heating system with gas cylinders in a private house, you should consult with specialists so that theoretical knowledge will help you with DIY installation.

Heating of a country house is carried out thanks to the ability to liquefy and pump a gaseous substance (technical propane, butane or their mixture with a butane content of no more than 60%) into cylinders, which are subsequently connected to the heating system through a device for reducing pressure (reducer). When leaving the cylinder through a reducer, gas, when exposed to low pressure, passes from liquid to its aggregate state, then enters a gas boiler, where it burns, releasing a large number of thermal energy. The volume of the cylinders is 50 liters, they are filled to 80%, since the gas is capable of expanding, and filling the cylinder to a larger volume creates the risk of it bursting.

Reducer for gas cylinders

Thus, to install heating a house with liquefied gas, the following elements are required:

Gas boiler with burner
Gas containers with a volume of 50 l.
Reducer for each cylinder
Ramp for connecting several cylinders
Shut-off valves
Pipes and hoses for gas pipeline installation and connection into a single system.

Advantages and disadvantages

The advantages of heating a private house with gas cylinders are:

Minimum fuel consumption and affordable price.
Environmental safety of gaseous substances.
Ease of creating an autonomous heating system and connecting it
Stable pressure in gas heating pipes.
The efficiency of using gaseous fuel compared to solid fuel. Yes, heating country house gas cylinders will allow you to save significantly if you use a properly adjusted boiler, which, in the absence of homeowners, will maintain the air temperature at +5 or +7 degrees only to maintain the operating condition of the heating system.
The ability to install an autonomous gas system even in the most remote areas from civilization, while you can not only heat the premises, but also use hot water.
High heating efficiency due to rapid combustion of fuel and, accordingly, immediate release of thermal energy.
Convenient connection of gas heating at any time.
There is no need to allocate a large area in the house for storing fuel, compared to solid fuel.

Elements heating system

Among the disadvantages, the following points can be noted:

It is not advisable to place gas containers outdoors in the open air, because at low temperatures ah, condensation occurs, preventing the gas from escaping when freezing. It is best to place them in an insulated metal or plastic box separately from the living space.
Inconveniences for refilling gas tanks, especially in remote areas.
If the system is adjusted incorrectly, ineffective gas fuel consumption may occur.
Purchasing gas from unverified suppliers can lead to unstable and inefficient operation of the heating system and incur financial costs.
For safety reasons, it is recommended to entrust the installation of gas heating to specialists.
For a long period of time, continuous use of this type of heating may not be profitable.

Connection diagram

As mentioned above, to transfer gas to the boiler, each cylinder is connected to the gas heating system using a reducer. In this case, either a separate reducer can be used for each cylinder, or a common one for several pieces. A separate gearbox is a safer, but also more expensive option.

Several cylinders can be connected to the heating boiler at once, this will increase the time for refueling them. In this case, a ramp is used, i.e. a special manifold that distributes the capacity of the cylinders into the main and spare ones. The gaseous substance is first released from the main tank, after which the collector switches the boiler to the reserve group. At the moment of switching, a sound signal is heard.

As when connecting any other heating system, gas heat supply requires the installation of convectors for individual rooms of the building. Usually, gas convectors compact and resistant to low temperatures. Radiators can be equipped with automatic temperature controllers, air vents, shut-off valves, flow sensors. The heating system can be designed for both natural and forced circulation coolant. With natural circulation there is no need for sensors and air vents, this can save money.

Connection diagram for gas cylinders

The pipeline layout connecting the gas boiler and radiators can be two-pipe or single-pipe. The first connection option involves a coolant supply and return system on each of the radiators, when it enters the heating device through one of the pipes and returns to the boiler cooled through the other. This allows you to achieve a uniform degree of heating of the coolant in all radiators of the building. When connected two-pipe system Radiators can be arranged in parallel-series or individually. With single-pipe wiring, it becomes possible to regulate the temperature of each convector separately. Moreover, it implies tangible financial expenses, since it becomes necessary to install a significant number of pipes for supplying radiators. A similar scheme consists of sequential transfer of heated coolant from one radiator to another. The disadvantage is that the coolant gradually cools down, and the last battery will always be less hot than the first.

For effective and safe use gas heating system, some recommendations should be followed:

Economic benefits with this type of heating occur provided that the area of the heated room does not exceed 100 m2, and the walls of the building are well insulated to avoid heat loss. How larger area building, the more cylinders are used to heat it.
It is better if the heating boiler is a backup one, operating in a single system with other heating devices.
If the cylinders are located outdoors, they should be forced to be heated using air from the boiler room or placed in an insulated gas cabinet. In this case, the cabinet must be equipped with ventilation holes at the top and bottom.
It is prohibited to place gas cylinders inside basements, cellars, ground floors.
It is prohibited to heat cylinders electrical cables and heating devices.
It is necessary to ensure that the cylinder is not filled to more than 85% of its volume. Otherwise, at temperatures above +25 degrees it may burst.
When installing a gas pipeline, pipes with a wall thickness of at least 2 mm should be used. In this case, they are placed in a foamed case, and the boiler is connected using a flexible connection. A durite hose connects the reducer and the gas pipeline.
A prerequisite when using autonomous gas system heating is to ground the boiler, ensuring free access to the equipment. Access is required to check and refill cylinders.
It is prohibited to store the cylinders in a tilted position, or to drop them; they must be firmly secured using clamps.
It is recommended to install gas leak detectors.
It is prohibited to store empty gas cylinders inside a residential building.

Those who own private houses or summer cottages are one way or another faced with the question of how to support comfortable temperature in it even in the most severe frosty winters. The variety of types of heating is quite large, but one of the most common is gas heating with cylinders. Why it is so widespread and how they can provide for their home should be understood in more detail.

Prices for gas cylinders

Gas equipment for heating a cottage

When the question arises about heating with gas cylinders, it is best to contact specialists about this, so the likelihood of error will be reduced to zero. But this does not mean that you do not need to know thoroughly the process of heating with gas cylinders. In order to install this type of heating into a house, a certain combination of devices is needed:

With help gas boiler gas fuel is converted into heat energy.
In order for the boiler to function, it is necessary to install a burner that ignites the liquefied gas in the boiler.
Directly a gas cylinder as a source of fuel.
The reducer connects the cylinder and the boiler.
Pipes are necessary so that the entire system is interconnected and can work holistically.

Can be used for heating a home Various types cylinders, which have their own positive and negative characteristics, taking into account which a choice should be made. They are:

Cylinders made of metal or steel.
Polymer-composite.
Metal-composite.

Metal cylinders

This type of cylinders became popular a long time ago for a simple reason - previously there were only cylinders of this type.

However, time-tested, they have a fairly large number of disadvantages, which are not known to everyone, because they continue to be used to this day:

The first disadvantage of this type of gas tank is its heavy weight. When empty, it ranges from 4 to 30 kilograms.
The lack of transparency is not a very convenient characteristic for a device in which it is desirable to see the amount of content remaining there. With a design made of opaque material, it is not possible to control the filling level of the cylinder.
Lack of sufficient level of security due to lack of equipment necessary protection if such a tank is affected by improper operation. There is a high probability that it may explode, scattering into many small fragments.
It is not resistant to corrosion processes, because it is made of metal. The possibility of being exposed to water, which causes corrosion, is great during transportation, storage and during use. In addition, there is water in the form of steam in the inside of the tank, which is also dangerous due to the occurrence of a corrosion process.
The material is not strong enough to be impact resistant. Despite the fact that the metal itself is durable, it can be damaged due to prolonged use. different ways. As a result, it may turn out that another blow will lead to cracking of the cylinder shell, which promises unpleasant consequences.
During transportation, cylinders often come into contact with each other, and this is dangerous due to the possibility of spark formation. What will a spark in combination with gas lead to?
There is no supply of a bypass valve, which serves as insurance in the event of an over-inflated tank, or an incorrect filling process, or heating of the surface of the cylinder.

Polymer composite cylinders

This type of gas container was invented recently. They are produced using fiberglass thread. They have a mass that is 40% less than those made of metal. They are quite convenient for storage and require little space. The advantages can be listed:

Providing the housing with impact-resistant properties and explosion protection. This is due to the fact that the cylinder is braided with a special casing, which in the event of an explosion will compensate for the force of the impact. In case of an emergency, only this casing will have to be replaced.
There is no possibility of sparks forming during contact, which also plays a role regarding the explosion.
The gas containers are made in such a way that if they are near an open flame or in conditions of temperature exceeding 100 degrees, they do not succumb to explosion.
In addition, such cylinders are transparent, which makes it easy to observe the amount of fuel in it.
It is not subject to corrosion due to its composition. This ensures good visibility and maintains the integrity of the material.

Important: the cylinder can operate in a temperature range between -40 and +60.

The cylinders are equipped with a bypass valve, which eliminates excess pressure in the event of overheating of the cylinder and pumping its contents. These parameters exist due to the presence of a fusible link, which, if necessary, will melt and give space for excess gas to escape into the environment.

Metal-composite cylinders

A type of gas container that is intermediate between the two previous options. All the parameters that the cylinder has are at an average level, such as weight and safety. There is internal corrosion in it, since it is equipped with a metal liner inside. The material is not transparent; the design provides for various monograms.

Choosing a boiler for heating a dacha with gas cylinders

When choosing a boiler for a heating system using a gas cylinder, you need to pay attention to the following number of parameters:

The amount of fuel consumed per hour. This parameter depends on how much area needs to be heated.
Pressure level. Gas consumption depends on pressure; the lower this indicator is, the lower the consumption will be.
Automatic equipment. Some boiler models have the ability to switch the heating power and set the required level.

Also important parameter is the efficiency, which should be close to 100%. The type of burner that will be installed in the system depends on this:

Inflatable.
Atmospheric.

The first type of burner is characterized by the fact that the gas is burned completely, this ensures maximum high degree Efficiency Plus, equipping with automatic heating level switching systems can save 20% of gas. Some models of this type are produced without a chimney, which significantly saves material investments in assembly and purchase of additional equipment.

When choosing heating equipment, you should carefully consider the choice of the cylinder itself, if the type for choosing one is metal. This type of container must have a special inscription indicating the date on which the fuel was filled and the number of the cylinder itself. The color of gas containers should be red or orange.

Important: it is not recommended to use cylinders without the characteristics listed above.

What you should know before installing a gas cylinder in your dacha

One of the main elements in a gas heating system is the reducer. It is needed for the reason that the degree of pressure in the cylinders is often an unstable value; it may depend on the volume of remaining fuel, what composition the mixture has, or the distance from the consumer. In this regard, you need a device that can produce a constant level of pressure, regardless of the factors that interfere with this.

You can select a gearbox according to the parameters indicated on its body:

Performance. To calculate what performance gearbox to buy, you need to start from the fuel consumption per unit of time. The ratio should be such that this gearbox parameter is greater than or equal to the boiler intake capacity. Gearboxes with minimum parameters performance cannot be installed in the house for heating.
Working pressure level. There are reducer models that allow you to adjust the pressure level in the range of 20-60 mbar. If you purchase another type of device, you need to pay attention to ensure that the indicators of the heating devices and the gearbox are equal. Standard models assume operating pressure from 30 to 50 mbar.

If it is necessary to connect the system using flexible hoses, you need a reducer equipped with a herringbone fitting. When installing rigid pipes, it is necessary to purchase a device that has threaded outlets.

Principles of installing a heating system

There are several options for connecting the entire heating system with gas cylinders in the house:

First option involves connection using curved pipes made of metal, manifolds and plastic hoses with reinforcement. The connection diagram in this option is linear, in which all gas containers are combined into one flow and they operate synchronously.
Second option is a system of cylinders that switches between each other. This is done using a gearbox with the ability to carry out such switching automatically or manually. The connection diagram looks like this: some of the cylinders are connected and in operation, and some are a reserve stock. In the event that the gas in the main part of the fuel tanks runs out, it switches to another. This allows you to save time when you need to fill the cylinders, because turning off the fuel supply to the system is not required. Another advantage is that gearboxes of this type have special valves that regulate the pressure level when it increases due to various external influences.

How to install a gas cylinder for heating a summer house

Rules should be followed when installing gas cylinders for heating, which will ensure the correctness of the process and safety:

The installation position of the gas container should only be vertical;
it must be installed in a place to which there is access so that, if necessary, the equipment can be inspected or replaced;
the distance from heating devices must be at least 1 meter;

Important: installing gas heating in basements or basement-type rooms is strictly prohibited.

It is important to remember that even if you are confident in your abilities and knowledge of how to install gas cylinders for heating, it is forbidden to do this yourself; you need to use the services of specialists, as in the case of repairing or replacing equipment. The sequence of actions during installation by the wizard is as follows:

The room (dacha, house) in which the gas cylinder will be installed must be well ventilated.
Preliminarily on open space The fuel container is checked for leaks. This is checked by soaping the monograms and fitting holes. If soap bubbles appear, the use of such a cylinder is prohibited.
The next thing to be checked is the integrity of the rod seals and connections in the uncorked state and in the closed state of the valves after the connection. The check is carried out in the same way soap solution according to a similar principle. If bubbles are detected, you should call the emergency service and take the cylinder out into the open air.
After checking the tightness of all devices, you can connect the entire system together using pipes and a gearbox. The scheme according to which the installation is carried out is selected in advance and the pipeline is laid according to the scheme.

Important: the pipe material must be steel, the pipe type must be bellows. The use of other types of pipes for gas heating is prohibited.

Storage and safety rules

The first thing you need to pay attention to is the amount of fuel that is allowed to be stored:

ten-liter containers in residential premises, provided that the container is sealed;
three-liter containers that have characteristics that are resistant to fire and shock.

Rules to follow when sending cylinders for storage:

when choosing a place to store gas containers on outdoors, you need to make sure that there is no direct sunlight in this place;
Only containers that have been checked for integrity are allowed to be stored;
if corrosion processes are detected on the surface of the cylinder, it is strictly prohibited to send it for storage;
the residue pressure level must be below 0.05 MPa;
the temperature regime for storage must be maintained within 45 degrees;
When storing, keep the distance between fuel containers more than half a meter from each other and from heating devices.

Advantages and disadvantages

The gas cylinder heating system has many positive characteristics:

are economical;
do not require additional devices for normal operation;
easy to install and replace;
no need for electricity consumption;
With this type of heating, oxygen is not burned.

However, there are several negative aspects to using gas equipment:

there is a possibility that the heating system will turn off if gas cylinders freeze on frosty days;
choosing a room for installing cylinders is quite difficult, since their installation in rooms with poor ventilation is prohibited;
gas has a higher density than air and if the system is not tight, it will fall into the lower parts of the building and, accumulating there, can cause unpleasant consequences.

Conclusion

The heating system, which uses cylinders, is quite simple and convenient, and also saves a good amount of money both during installation and during the period of operation. If you carefully approach all installation processes and equipment selection, you can eliminate all the disadvantages of this heating system.

Despite the emergence of new methods of heat supply, gas heating is still the best option both for a country house and for an apartment. But it is not always possible to connect to the distribution main. The way out of this situation is to heat a private house with gas cylinders. To do this, you need to choose the right boiler, calculate fuel consumption and read reviews.

The nuances of heating with gas cylinders

Properly organized heating using gas cylinders is important for houses with permanent residence, as well as for summer cottages. Liquefied gas is used as an energy carrier, which differs in its properties from natural gas.

In order to heat a private house using gas cylinders with your own hands, you need to familiarize yourself with the features of its organization. An important step is the choice of boiler, since it must be adapted specifically for this type of gas. In addition, the following factors are taken into account:

Estimated consumption volume. Directly affects the consumption when heating with gas cylinders and their reserve to ensure heat supply;
Preparing the container storage area. Safety measures must be observed;
Organization of gas transportation from cylinders to the boiler. Properly organized individual heating from gas cylinders should be safe;
Selecting a supplier for filling gas cylinders.

If you carefully read all the reviews when heating a house with gas cylinders, you can note the complexity of the configuration and installation of this type of heating supply. Therefore, it is necessary to calculate the parameters of all elements in advance so that after their installation they can ensure normal operation of the system.

Choosing a storage location for gas cylinders

Before deciding on the method of storing gas cylinders, it is necessary to correctly select their capacity. Currently, containers with a capacity of 5, 12, 27 and 50 liters can be used. If heating a private house with bottled gas will be regular, it is best to purchase containers with a maximum volume of 50 liters.

To supply gas, a line is made from the place where the cylinders are stored to the boiler. You can use several containers at once by installing a gas reducer on each. It should include two pressure gauges. One of them is necessary to verify the pressure inside the cylinder, and the second shows this value at the outlet. Using the shut-off valve, the intensity of the fuel supply is regulated.

The location for choosing their storage directly depends on how many cylinders are needed for the heating boiler. The estimated number of containers depends on the following indicators:

Total area of the house;
Heat losses in the building;
Minimum temperature in winter.

An important point is the place where the gas heating boiler using bottled gas will be installed. The length of the supply line should be minimal in order to reduce the likelihood of its depressurization and optimize gas consumption.

In addition to heating boilers, gas convectors can be used to heat the house. But they need to be installed in each room, which is not entirely convenient for a large building.

Separate room for cylinders

The best way to store gas cylinders for heating is preparation separate room. The rules for arrangement and requirements for it are described in detail in SNiP 2.04.08-87. Therefore, before installing heating using gas cylinders, you must read this document.

The best option is if the storage room is located in close proximity to the boiler installation site. In this way, the supply line can be made as short as possible. It is also necessary to ensure the following storage conditions for containers for heating a private house from gas cylinders with your own hands:

No flammable or lubricants should be stored in the premises;
It is prohibited to use any heating devices– convectors, heaters. The exception is pipes and radiators for water heating;
Security supply ventilation. The average air exchange rate is 12 m³/hour per 1 m² of room;
Each cylinder must be placed on a pallet. This is necessary to maintain stability in case of possible fluctuations in the capacity during gas release.

To ensure safety, the premises must be locked. Fuel supply for heating a private house with bottled gas occurs via a pipeline. If flexible hoses are used for this, kinks must be avoided during installation.

Heating boilers using bottled gas can be installed in the kitchen or in a separate boiler room. Fuel storage space should not be located in basements or basements.

Requirements for a cabinet for storing gas cylinders

An alternative to the above method is to use special metal cabinets. This is relevant for heating a dacha with gas cylinders with low fuel consumption.

Ventilation. To do this, the cabinet design must have ventilation holes;
Eliminating the possibility of sunlight hitting gas cylinders. This can lead to an increase in temperature on their surface;
All elements of individual heating from gas cylinders must be made from non-combustible materials. The same applies to storage cabinets;
Presence of warning signs and inscriptions.

How long does a 50 liter gas cylinder last for heating? It all depends on the nominal consumption of the boiler. But despite this, you can only store two cylinders in one cabinet. Optimal sizes the structures in this case will be 2000*1000*570. Before installing the cabinet, it is necessary to make a separate foundation. Its dimensions should exceed the dimensions of the structure by 15-20 cm.

The installation rules for heating a private home from gas cylinders with your own hands are also observed:

The minimum distance from doors and windows should be 5 m;
The wall to which the cabinet will adjoin is made of non-combustible materials.

Be sure to make special ones on the surface of the foundation ventilation gaps. Experts recommend grounding the structure to remove possible static voltage.

The design of the cabinet for heat supply using gas cylinders must include fastening elements for containers.

Calculation of the number of gas cylinders for heating

One of significant shortcomings Such heat supply is a constant replenishment of fuel reserves. Therefore, it is necessary to calculate in advance how many cylinders are needed for the boiler. There is no exact method for this. But there are a number of ways in which you can determine approximate fuel consumption.

To determine the consumption when heating with gas cylinders, you need to familiarize yourself with technical documentation boiler It indicates fuel consumption for both natural and liquefied gas. Usually in the latter case, manufacturers give the flow rate in kg/hour. For boilers with a power of 24 kW it is about 3.5 kg/hour.

In addition, the intensity of fuel consumption is taken into account. On average, to maintain normal temperature in winter period The heating supply of a private house with bottled gas operates from 12 to 16 hours a day. If heating season is about 100 days – total consumption for a 24 kW boiler it will be equal to:

3.5*15*100= 5250 kg

Those. On average, you will need 1 cylinder per day for a heating boiler with a capacity of 50 liters. This is the maximum fuel consumption, which can be reduced as follows:

Installation of automatic gas supply;
Acquisition modern models boilers with high efficiency;
Insulating the house to reduce heat losses.

But even these measures will not greatly affect fuel consumption. Almost all reviews about heating with gas cylinders indicate the relevance of installing this type of heating only in houses with small area and non-permanent residence.

The table shows how many cylinders are needed for a heating boiler depending on the area of the house.

These are not final numbers. For each heating system, an individual calculation is made of how many cylinders are needed for the boiler. It is also necessary to take into account the correct filling of the container. All liquid is first removed and the weight of the empty cylinder is measured.

When filling a cylinder, you can check its filling level by measuring the temperature level. The area where there is a gas mixture will cool the cylinder.

Choosing a boiler for balloon heating

Currently, manufacturers do not produce narrow-profile heating boilers using bottled (liquefied) gas. However, equipment designed for natural gas cannot be used without prior modification.

Before purchasing a boiler, you must make sure that the package includes a kit for adapting equipment for propane. The set includes nozzles with a wider nozzle and a kit for attaching them to the burner. The reinstallation procedure can be performed independently only if this is provided for by the design.

There are several types of gas heating boilers using bottled gas, which differ in operational and technical characteristics:

Burner type - open or closed. It is best to purchase heating boilers using bottled gas with a closed burner. For their operation, air is taken from the street using a coaxial pipe;
Installation – wall or floor. Most models with power up to 24 kW are wall mounted;
Number of circuits. To supply heat to your dacha with gas cylinders, you can purchase an inexpensive single-circuit boiler. If the house is planned permanent residence– it is recommended to buy a double-circuit model with hot water supply.

You can preliminarily calculate the flow rate for heat supply with gas cylinders by reading technical passport equipment. However, manufacturers often give the maximum flow rate at maximum power equipment. The lower the burner operating intensity, the less fuel will be consumed.

They have the best performance indicators gas boilers heating using bottled (liquefied) gas with a cast iron heat exchanger. It will last much longer than steel.
