Turnkey gas heating. Gas heating of a private house: main gas and bottled gas, choice of equipment Additional gas equipment in the house

In order to live safely and comfortably in a private house, the owner must be puzzled by installing a good heating system. There are several ways to keep the heat in the house, but the most popular of them is gas heating.

Today we will consider this topic in more detail, we will analyze what disadvantages and advantages gas heating has, how to choose a gas boiler and find out what heating options exist in this way.

The advantages of heating a house with gas are:

1. The price of the gas itself. It is the most adequate based on the labor costs for heating.
2. Low losses. Gas heating guarantees that 80-90% of the heat it generates will go to heat your home, and will not be wasted.
3. Despite the small size of the equipment, it is able to heat large rooms.
4. The unit is silent and does not require special care. The system is autonomous and can maintain the required temperature by itself, so you don't have to constantly monitor it.
5. There is no dirt from the gas boiler.
6. Double-circuit gas boilers not only heat the house, but also supply hot water.
7. Gas holders that contain gas are considered safe for humans.

As you can see, it is quite profitable to purchase such a heating system. But we must not forget about the shortcomings that any type of heating has.

Perhaps, when purchasing a boiler, you should not forget that:

1. The autonomy of the system is often provided by electricity. Therefore, in the event of its interruptions or malfunctions, the operation of the boiler will stop, fail. Electricity creates the thrust required by closed-type sediments, is responsible for the circulation of water. If it is turned off, for example, in winter, then there is a high probability of stagnation.
2. The autonomy of the system is acquired for a lot of money, which can reach several hundred thousand.
3. The room must be ventilated, have a chimney. This is necessary for the removal of exhaust gases. Applies to more open type gas units
4. When purchasing gas heating, you need to adhere to the climate of your area. Severe frosts will not survive the boilers of European brands, since they are not sharpened for sharp changes in Russian temperatures.
5. The deterioration of the burner reduces the efficiency of the gas boiler. But this is more likely not a minus, but something that should be borne in mind.

Calculation of gas consumption for heating a house

And now let's calculate whether it is so profitable to install gas heating in a private house. To do this, we calculate how many liters are spent on heating.

To calculate the gas consumed, it is necessary to multiply the amount of kV needed for heating the house by one tenth of the volume of gas. Then it will turn out to find out how many cubic meters of gas are consumed in one hour.

For example, we have housing with an area of ​​250 square meters. Then a 25 kV boiler is needed to heat the house. Then:

25 kV * 0.1 m 3 \u003d 2.5 m 3 / h.

So, per day is spent:

2.5 m 3 / h * 24 h \u003d 60 m 3

For a month (we take 30 days):

60 m 3 * 30 d \u003d 1800 m 3

For a year, they consider this: they choose three cold months and add three more months to them, during which the boiler will work at half strength. For convenience, they take 100 days in the first case and 100 days in the second case. Then for the year it turns out:

(60 m 3 * 100 d) + (30 m 3 * 100 d) \u003d 9000 m 3

For houses with a smaller area, this figure is, of course, less. In addition, what comes out mathematically does not always correspond to practice. Usually the real figure is less than the declared one.

The calculation takes into account only heating.

To reduce the amount of heat loss, gas consumption, simple manipulations will help:

1. It is necessary to pay attention to the thermal insulation of the house. This also applies to the roof.
2. Change, if necessary, windows to plastic ones and replace doors.
3. Install a heat accumulator, heating radiators, that is, equipment that allows you to save heat.
4. Insulate floors.

Choice and types of gas boilers

You should know that. Each species has a right to exist in its own way and will provide good gas heating for a private house.

Single and double circuit boilers

Single-circuit boilers are intended solely for heating and do not perform any other functions. Purchased if you do not need to heat hot water directly from a gas boiler.

Such boilers work directly on the heating system. They can also be used to heat an indirect heating boiler, which in turn is used to provide the house with hot water.

Double-circuit gas boilers ideal for both space heating and water heating. It should be noted that double-circuit boilers are not always effective for heating water. Usually enough for only one active point. If, for example, you go to the shower and someone decides to wash the dishes, then you will already be taking a cold shower. You should take this into account when buying.

Wall and floor boilers

Wall-mounted boilers are safe and automated, but often work on only one type of gas - natural. (There are models in which you can change the burner and they will work on liquefied gas). They can be installed in kitchens, as it has a smaller size compared to the floor.

The power of wall-mounted boilers is often limited to 35-40 kW. Therefore, if you want to make gas heating in a large house, you will either have to install two wall-mounted boilers in a cascade mode of operation, or install a floor boiler.

Floor boilers are capable of heating large rooms, as they have a large capacity. They are universal in terms of fuel consumption: natural, liquefied, main gas is suitable. They are energized and independent. Often a cast iron heat exchanger is used. Due to their design, they have an efficiency lower than that of a wall-mounted one, but at the same time a longer service life.

Gas heating options

Reading the article, you probably noticed the mention of liquefied and trunk gases. A reasonable question arises: how do they differ? Is it more profitable to heat a private house with a pipeline or cylinders? Now let's figure it out.

Types of gas heating:

1. Trunk. The most environmentally friendly. It consists mainly of methane, which is purified from various impurities, leaving a meager amount of an odorant that allows people to detect gas leaks. However, installing it can not do without a headache. You will need to coordinate documents with official bodies, you will need to worry about sufficient pressure in the pipes, and the wiring itself is a rather complicated undertaking.
2. Liquefied. The same gas in cylinders of bright red color, in which the familiar propane-butane mixture is stored. But they will not interfere if you install an underground tank in which you can safely store cylinders. It needs to be replenished once or twice a year. Suitable for all boilers.

As you can see, liquefied gas is more profitable than main gas, but it is important to remember that about 50 liters of gas are placed in one cylinder. One such cylinder is changed every two to three days. While the main pipes enter your apartments. And gas holders, in which gas is stored in cylinders, are filled with a special machine. This fact is taken into account in winter. The storage facility must be cleared of snow.

Alternative ways to heat a private house

Gas is not the only source of heat that can heat your home. There is also indoors. But are they so beneficial compared to a gas system?

Ways of alternative heating of a private house:

1. Electricity. The most common and affordable source of energy, however, it is almost the most expensive. It may simply not be enough to heat a private house, since not every power grid will be able to transfer the amount of energy necessary for heating. Malfunctions in the winter are not ruled out. Not the most economical and practical option.
2. Diesel. Diesel fuel has a high price. It tolerates a very unpleasant aroma, from which you can’t get rid of anything either at home or on the street. And if you take diesel fuel of insufficient quality, then the heating system may break down. Not the best option.
3. solid fuels. Coal and wood. They need to be supplied to the heating system two to four times a day. Every day it is necessary to remove ashes from the heating system. Naturally, a considerable amount of fuel of this kind is required to heat a house per year. This requires large sums of money. For them, you should have a separate warehouse, in addition, they are dangerous, as they can emit carbon monoxide. In this regard, gas installations are more cost-effective and safer.
4. Pellets. These are special granules that are made from peat and wood waste. Its disadvantages are similar to the disadvantages of coal and firewood: you need a room to store a large amount of pellets, they do not smell very good and they often need to be loaded into the heating system. The difference is that they are cheaper than all the fuels listed above, except for gas. Yes, and you need to load them less often than firewood or coal: no more than once a week. Not a bad option.

Obviously, gas heating wins in many ways: efficiency, ease of operation, minimal heat loss, low cost of the fuel itself. Therefore, if you decide to install a good heating system, then opt for a system with gas heating of the coolant.

Which boiler is better: single-circuit or double-circuit?

Which boiler to choose: wall or floor?

If you have the opportunity to connect to a gas supply system, then when choosing a heating method, it becomes obvious that gas heating is the best option. This option is the most efficient and comfortable, therefore it is very popular both in providing heating for residential and industrial premises.

Types of gas heating

Depending on the equipment used, there is a difference between this heating method into the following types:

• . In this case, a water heating system is installed in the house, but a gas boiler is used to heat it. This equipment can be floor or wall-mounted, single or double-circuit, and also have an open or closed combustion chamber. Heat exchangers can be cast iron, they are usually used in floor boilers and steel, they are more often installed in wall models. If the combustion chamber is open, then the air to ensure the combustion process comes from the room, and when it is closed, then from the street.

• Convectors. In this case, convectors are used for heating, but it is not necessary to install heating radiators and pipes for supplying coolant. A gas convector is easy and quick to install, and at the cost of heating, this option will be cheaper than similar electrical equipment.

• infrared emitters. This is modern equipment, it is usually used for large rooms and operates on the principle of solar radiation. Now there are models with a capacity of 1.5 kW, so they can also be used to heat cottages.

Device Features

The design of the heating system will depend on the equipment used. If a gas boiler is installed, then in addition to it, there must be:

• Heating radiators.
• The piping system, it is needed to supply the coolant.
• The pump, it is necessary to improve the circulation of the liquid.
• Expansion tank.
• Automation system for process control.
• Safety devices.
• Devices that are necessary for the removal of combustion products.

If convectors or infrared radiators are used, then in this case there is no need to install a piping system and radiators, since the space is heated directly from the installed equipment.

Operating principle

Gas heating has a simple and understandable principle of operation. When a gas boiler is used to heat a room, it is connected to a heating system consisting of radiators and pipelines, which usually contain water, but may also contain antifreeze. Getting into the heat exchanger located inside the boiler, the water is heated, after which it moves through the piping system to the radiators. The movement of water can occur by gravity, then the pipes and radiators are installed with a certain slope or with the help of a circulation pump. After the heated water through the radiators gives off heat to the room, it returns to the boiler again and the whole process is repeated.

When convectors or infrared radiators are used, the specified equipment does not require additional installation of pipelines and radiators, since it independently heats the air in the room.

Areas of use

Gas heating can work from the main gas pipeline or on liquefied gas. If there is a gas pipeline, then an apartment, house, industrial premises can be heated in this way. In the absence of a centralized gas supply, equipment operating on liquefied gas is used. It is usually used in private homes, shops, cottages.

Infrared gas radiators are usually used to heat large areas, such as shopping centers, industrial buildings, sports or concert halls. Such equipment is installed under the ceiling, which is very convenient, since it does not take up free space. Now low-power infrared gas emitters have appeared that can be used to heat a private house.

How to choose gas heating

When choosing this type of heating, it is necessary to take into account whether people will be in this room constantly or periodically. If there is no need for gas heating to work constantly, then it is better to install convectors or infrared emitters. In this case, there is no coolant in the form of water, so it will not freeze when heating is not carried out.

If it is necessary that the heating of the room takes place constantly, then it is best to use water heating, in which water is heated using a gas boiler. This option allows you not only to constantly and evenly heat the room, when using a double-circuit boiler, you will also be provided with hot water that can be used for various domestic needs.

If we talk about gas boilers, they can be wall-mounted or floor-standing, the former are more compact. If the boiler is single-circuit, then a capacitive boiler can be installed, but it is easier and more convenient to get hot water using double-circuit equipment in which a flow heat exchanger is installed.

Floor boilers are more expensive, they need more space, but the power of such equipment will be higher. Their installation usually requires a separate boiler room. In addition, when installing a floor-standing boiler, there must be a vertical smoke channel, which can be made inside or outside the building.

Floor boilers usually have cast-iron heat exchangers, so their service life is longer than that of wall-mounted models. Such equipment can be equipped with a furnace with a fan burner, which allows using not only gas, but also liquid fuel or pellets as fuel.

Advantages and disadvantages

Since gas heating is mainly carried out using a boiler, a system of pipes and radiators through which water moves, we will consider the main advantages of this solution:

• High efficiency.
• Since the system is a closed cycle, the initial volume of the coolant does not change.
• If you have certain skills, then you can make water gas heating yourself.
• Uniform heating of all rooms.

The disadvantages of a water heating system, which is heated by gas, will be as follows:

• It is necessary to constantly maintain the cleanliness of heating radiators, since when they become dirty, the heating efficiency decreases sharply.
• After switching on, water heating warms up the room more slowly than air heating.
• Pipes and radiators are gradually damaged by corrosion and may fail.
• The water that acts as a heat carrier should have a minimum of salts, so it is best to use distilled water.
• In winter, it cannot be turned off, since the coolant may freeze, with the exception of the use of antifreeze.

If we talk about the use of convectors or infrared emitters, then their advantage is that there are no pipes and radiators, they can be turned on and off in any weather and the cold room is heated faster. The main disadvantage of such heating is that the temperature near the heating equipment will be higher than elsewhere in the room.

Operating rules

The gas boiler is the main element of the gas heating system and to ensure its safe and reliable operation, specialists must carry out routine inspections at least once a year.

Only qualified personnel can install gas equipment, but before doing so, you must obtain all relevant permits.

When deciding on the restructuring of a room for heating of which gas heating is used, it is necessary to agree on a new project. In case of non-coordinated construction work, gas equipment may not work correctly and this will lead to the formation of carbon monoxide.

Gas heating will be an effective and affordable way to heat both residential and industrial, commercial or other premises. It is easy to maintain and it can operate both on natural gas, when there is a gas main nearby, and on liquefied gas, when there is no way to connect to a centralized gas supply.

Gas boiler as a heat source used everywhere and is considered the best means of heating the room.

Natural gas - the most accessible and inexpensive energy source. That is why gas heating is so popular.

Even in the absence of the possibility of connecting to the main line, one can consider alternative home gasification projects(gas holder, gas cylinders).

Gas heating system

The use of gas boilers for space heating is the most common way to heat private houses. When heating a house with gas no waste is generated: no dust, no dirt.

Distinguish between floor and wall boilers. They have the following characteristics:

1. Floor appliances have a significant mass due to the cast-iron heat exchangers installed in them. They need a separate room. They work up to 50 years due to the anti-corrosion properties of cast iron.
2. Wall gas boilers can be installed in the kitchen or in the corridors. The heat exchangers in them are made of steel, so they have less weight and a fairly presentable appearance, the devices fit well into the home interior. Serve from 15 to 20 years old, have a lower cost.

There are two types boilers: single-circuit, used exclusively for heating, and double-circuit, which also heat water.

Devices are classified and by type of combustion chamber. She happens:

• open- consumes air from the room (accordingly, additional ventilation is required);
• closed— takes the street air.

Principle of operation, scheme

The device of the heating system using a gas boiler is standard. It contains:

• heat source;
• water as a heat carrier;
• circulation pump;
• pipeline;
• expansion tank;
• heating elements;
• shut-off and control valves.

Photo 1. Scheme of heating a private house using a gas boiler. Radiators and underfloor heating are used for heating.

Presented on the market many models gas boilers, but fundamentally, they practically do not differ from each other. Using internal sensors and thermostats, the controller supplies natural gas to the combustion chamber. In the heat exchanger, water is heated to the required temperature and pumped into the heating circuit by a pump. Heating will go on until the required temperature is reached.

In the future, automation will maintain the temperature at a given level, without requiring human control. Double-circuit boilers involve the use of water from a heat exchanger for domestic needs, but fluid intake somewhat limited to maintain balance and depends on the size and power of the unit. Some gas boilers are used in the "warm floor" system and even for heating pools and greenhouses.

Advantages and disadvantages

Gas boilers are the most economical sources of heat, but They also have other positive aspects:

• They can heat large rooms.
• They have a high efficiency 80—95% ).
• Warm up rooms quickly.
• There is no need to monitor the boiler, everything is automated as much as possible.
• If for some reason the flame of the burner goes out, then it will be re-ignited.
• Easy to operate and maintain.
• Have a long service life from 15 years old).
• They allow you to control the temperature in the house to a degree.
• The use of such boilers is safe.
• The devices are compact.

Minuses gas boilers:

• It is not economically feasible to place these devices in houses with an area of less than 100 m2, their use in such conditions is considered extremely dangerous.
• Installation of gas boiler equipment requires the preparation of the necessary documentation (you need to obtain permission from Gaztekhnadzor).
• It is necessary to install a chimney to remove exhaust gases.
• The room in which the boiler is installed must have a separate exit to the street and forced air ventilation (especially for boilers with an open combustion chamber).
• With low gas pressure or burner failure, the efficiency of the device drops sharply.
• Requires the installation of expensive automation that provides security control.

The most profitable is the installation of a gas boiler in a house connected to the main gas supply network. From the central pipe, a supply is made to the house directly to the heating equipment, which allows you to completely forget about the issue of space heating, energy delivery and operating costs. These heating systems comply with all modern environmental standards.

The autonomous gas heating system includes gas tank or gas bottles. It is advisable to plan and take into account the installation of a gas tank on the site during development.

This will make it possible to lay the gas pipeline underground to the boiler room and kitchen. The use of balloons is practically unlimited.

When calculating the efficiency of heating private houses with liquefied gas, it must be taken into account that one 50 liter bottle accommodates 35-42 liters of gas. Heating consumption 100 sq. m. per day for any boiler is 15 l. It must also be remembered that the cylinders are filled once a week. Heating a house with gas cylinders can be considered profitable under the following conditions:

• The size of the house is smaller 100 sq. m.
• The building is well insulated.
• The gas boiler is a backup.
• In the future, gasification of the settlement is planned.

Back in the Soviet years, heating systems used autonomous gas water heaters. These installations are the simplest of all those used in heating systems using natural gas. Advantages of AGV installations:

• the simplest design, providing ease of control;
• low price;
• compactness;
• independence from electricity;
• reliability.

Negative aspects of the units - short service life, frequent failures of automation, condensation.

Appliances remain popular because of cheapness And constant increase in electricity tariffs.

How to make a heating system with your own hands

In a private house, you can mount a gas heating system with your own hands. This requires:

• make the necessary thermal and hydraulic calculations;
• draw up a working draft with a gas heating scheme;
• purchase materials and equipment;
• carry out the installation;
• test the heating system under high pressure;
• put into operation.

When developing a gas heating scheme, they are determined with coolant circulation: decide whether she will natural or forced. An important point is also the choice of one-pipe or two-pipe wiring of the heating circuit.

After choosing a heating scheme and piping you can calculate the required power boiler, circulation pump and radiators, as well as determine the diameter of the pipes, the number and size of them.

Types of boilers

Having decided on the power of the gas boiler, proceed to the choice of the device.

Regardless of the type of boiler, the main task of the owner is to ensure the efficient operation of the most important communication system at home. with minimal financial and labor costs.

Installation of equipment

Installation of the heating system begins with the installation of the boiler.

Required Tools for installation of the heating system:

• roulette;
• perforator;
• level;
• expander;
• gas, adjustable and conventional wrenches;
• screwdriver or screwdriver.

For fastening use 4 screws with diameter 6-7 mm. Using a level, check the accuracy of the installation. After that, a connection to the water supply is made using a coarse water filter. Install ball valves. Connect the chimney.

Attention! Connect the boiler to the gas pipeline only a specialist should.

After installing the gas boiler, they proceed to laying the pipeline according to the scheme. There are three types of pipes used in heating systems:

• metal;
• metal-plastic;
• polymeric.

Best suited for the heating system of a private house plastic pipeline. He is not afraid of changes in temperature and pressure. Its installation is carried out using a special kit that allows you to reliably solder the elements of the system.

Choose radiators taking into account the required power. There are different types of batteries on the market:

• steel;
• cast iron;
• aluminum;
• bimetallic.

Photo 3. Bimetallic radiator. Such devices are often used in gas heating systems.

Today, it is gas equipment for home heating that is very popular, since natural gas is the most profitable option. The gas heating system, in addition to the heating device itself, includes gas pipelines that provide fuel supply, pipes, radiators and other auxiliary equipment.

Gas heating equipment has many advantages:

• rapid heating of the system;
• high efficiency = 80-98%;
• there is no need for the constant availability of fuel reserves;
• independence from electricity;
• the heating process is maximally automated;
• emits a minimum of harmful substances;
• low cost of fuel.

domestic hot water supply

Distinguish 3 types of gas equipment for heating a private house:

• gas boilers;
• convectors;
• infrared gas emitters.

The latter type is mainly used for heating large areas. And the first two are suitable for heating a house or apartment.

Infrared equipment is placed under the ceiling. The emitters are a casing with a reflector directed to the floor with a ceramic nozzle in the form of flat plates with holes. Between the nozzle and the casing there is a space into which the fuel mixture is supplied, which heats the tiles to a high temperature. Then the combustion process is carried out already on the ceramic element, due to which heat from it enters the room. A significant advantage of an infrared gas emitter is the small amount of combustion products that quickly enter the ventilation system.

gas boilers

The most optimal equipment for heating a house is a gas boiler. It is chosen in terms of power in accordance with the area of ​​\u200b\u200bhousing, as well as the level of its insulation. For heating a private house, a unit with a capacity of up to 60 kW is usually enough. You can also choose a device that will not only heat the room, but also produce hot water for domestic needs.

There are gas boilers on the market for wall or floor placement. But you need to pay attention that the floor options are more powerful than the wall ones. The choice of gas units is huge, they differ in the type of combustion chamber, the material of the heat exchanger, the type of gas burner, the presence of various modern functions, etc. Most gas boilers are capable of operating on both main and liquefied fuels.

Convectors

The advantages of a gas convector are compact dimensions and ease of installation. But its adjustment should be done by specialists. Modern convectors fit well into any interior and are safe. Their service life depends on the material from which they are made and varies from 17 to 45 years.

Convectors work both from natural, and from bottled gas.

Gas heating installation diagrams

The installation of gas equipment for home heating may differ depending on the type of coolant circulation selected in the system:

• natural;
• forced (using a circulation pump).

Natural circulation of the coolant

In order for water to move freely through the pipeline system at a certain speed, pipes with a larger diameter and a slight slope should be installed. This option provides a larger volume of water in the pipeline than a forced circulation system. If the coolant moves slowly, the heating efficiency will decrease, and the last radiators in the system will remain cold. Therefore, for houses of a large area, the gravity system is not suitable.

The advantages of natural circulation of the coolant include independence from electricity.

Forced movement of the coolant

A system with forced movement of the coolant is more efficient - water of sufficient temperature quickly enters even remote radiators. If necessary, the speed of movement of the liquid in the pipes can be adjusted by means of a pump. The forced system is more convenient to operate, but it depends on the power supply. Therefore, for regions where electricity is often turned off, it is better to install a heating system with natural circulation of the coolant. But if you still want pump-controlled heating, you will have to purchase a generator to ensure its smooth operation, which will lead to additional costs.

Wiring methods

There are three types of piping:

• single-pipe;
• two-pipe;
• radiation.

Single pipe wiring

A single pipe system is a series connection of all elements to one pipe. This wiring option is the most economical, as less material is spent. However, it cannot reproduce the same heat dissipation of radiators. The coolant, having reached the last battery, loses its original temperature. You can compensate for heat losses by adding additional radiators to the last sections.

Note! It is possible to balance a single-pipe heating system if thermostats are installed on each radiator, which allow you to change the volume of coolant passing through it. To avoid disturbances in the circulation of water in the system, a bypass should be connected to each radiator, through which the coolant that has not entered the battery will pass.

Two-pipe system

In a two-pipe system, two parallel threads of radiators are made. In this case, the consumption of pipes is greater than with a single-pipe version. A coolant of the same temperature is supplied to each pipeline string, so the heat transfer will also be the same. It is also allowed to install thermostats on each thread of a two-pipe system, but without bypasses.

Due to convenience and high efficiency, a two-pipe system is more often used, although this option will require more pipeline.

Beam wiring

The beam wiring system is the most expensive in terms of the number of pipes. It assumes that each radiator has connections to the supply and return pipes. The heating device is connected to the radiators through a collector - an element that has one input and many outputs. In this case, you can adjust the temperature on the collector.

Gas heating, made using beam wiring, is the most reliable. Even if one radiator has problems, all the others will be able to work. This option is chosen if the pipes are hidden under the screed.

Connection to the gas line

You can connect to the gas main if the gas pipeline is nearby, and with the official consent of the gas service. In advance, you should draw up a project for gasification of the house. To do this, attract specialists from a company that provides these services and has the appropriate license.

The location plan indicates the location of the tie-in of new gas pipes. All plans and schemes are submitted for approval to the gas supply company. After obtaining official permission, you can begin work on the installation of the heating system. Installation and connection should only be carried out by specialists.

If there is no distribution substation in your area that lowers the gas pressure, you should install a reducer that will perform this function when supplying main fuel to the house.

Features of the autonomous heating device

If there is no central gas main nearby, then you will have to stop at the option of autonomous heating of the house on liquefied fuel. Most gas boilers and convectors are used for both natural and liquefied gas.

Cylinders with fuel must be located outside the residential building in a special metal ventilated container. Usually containers of 50 liters are combined into a group of three to ten pieces. The gas is supplied through a hole in the wall and container through a pipeline to the gas device.

For heating a large house, it is more convenient to use a gas tank so as not to constantly change gas cylinders. A gas storage tank is a metal container located above or below the ground. A considerable amount will have to be spent on the installation of a gas tank, but it will last for a rather long time and can provide the heating system with fuel for a long time without refueling. You can save on gas storage if you agree with neighbors and organize the installation of the tank by common efforts.

Note! The gas tank should be located at a distance of at least 10 m from housing.

The advantages of gas autonomous heating include:

• independence from the gas supply company;
• the ability to control the quality of fuel;
• system durability;
• reliability.

The downside is the need to independently organize the delivery of gas.

Elements of an autonomous gas system

Mandatory elements of any autonomous system are:

1. Heat generator: gas boiler or convector.
2. Pipeline with radiators. The most optimal material for pipes is metal-plastic.
3. Shutoff valves - it is installed to increase fuel economy. The main components are ball and shut-off valves, gate valves and needle valves.
4. The maximum savings in the operation of the heating system can be achieved by installing an automatic control and adjustment system. Automation changes fuel consumption depending on the temperature in the premises. Modern functions that save gas are built into the new models of units. But even if the simplest design of the boiler is installed, you can purchase the equipment separately.

An economical and convenient gas heating system can only be designed by a specialist. If you do not have experience in this matter, it is better to entrust the development of the project to the appropriate company.

I think it would be superfluous to talk about the importance of heating, especially if the temperature outside is below zero. For thousands of years, people have tried in every possible way to heat their homes. At first, these were bonfires, fireplaces, but with the development of technological progress, a method of heating also developed. Today, the most popular type of heating can be called gas heating in a private house, so let's take a closer look at it.

The main advantages of gas heating

The main advantage of gas heating is low cost. Thus, a kilowatt-hour of thermal energy obtained from gas combustion is only 30 kopecks, which is two times cheaper than when heating with wood. In general, gas heating in a private house is a system designed to heat a room using thermal energy obtained from gas combustion. Such a system consists of a gas boiler equipped with all the necessary associated devices, a gas pipeline and a heated coolant supply system. In most cases, water acts as a coolant - this is the most reliable and at the same time the cheapest option.

Important! In no case should you confuse main gas with liquefied gas! If you heat a private house with gas in cylinders, then it will cost six to seven times more than, for example, the same one.

And now directly about the benefits of heating. Almost all of them are related to the features of the boiler, let's look at them:

1. Gas boilers have small dimensions when compared with other analogues, and this is very valuable, especially when free space is limited;
2. Thermal energy obtained by burning gas costs significantly less than when operating other systems;
3. During the operation of such boilers, practically no noise is emitted;
4. Finally, gas boilers are very easy to use, they do not need regular cleaning, and it is enough to carry out planned work once a year.

Schematic diagrams

In general, there are only two such schemes:

1. Gas boilers.
2. Gas.

Let's talk about each of the options.

A gas boiler

A distinctive feature of gas boilers is that when the fuel is burned, a liquid is heated, which then spreads through the heating devices by natural or artificial circulation. Such devices for heating can be radiators, registers, underfloor heating, etc.

There may be several options for the execution of boilers, and the choice of one or another model will completely depend on what your needs are.

Single and double circuit

Single circuit devices designed exclusively for heating a private house. And no options. The volumes of the coolant in it are constant, they do not change.

Unlike him, double-circuit boiler can combine its direct "duty" with heating water for household needs. It can be, for example, a storage tank equipped with a separate burner. Of course, in this case, the boiler becomes part of not only the heating system, but also the water supply system.

Artificial and natural circulation

Gas heating in a private house can be done using boilers with natural circulation, at which air from the house enters the burner, and combustion products enter the general ventilation, and devices with artificial circulation. In the second option, the air necessary for gas combustion comes from the street, and the combustion products, on the contrary, are discharged to the street through a separate pipeline.

What are the differences between both options? Actually, there are only two of them:

• An artificially ventilated boiler can be installed directly in a residential area.
• A device with natural circulation needs a separate room, which has a wide door and window, and its area must be at least 4 square meters.

Important! Regardless of the type of boiler chosen, the connection and start-up of the heating system must be carried out exclusively by employees of the gas service!

Condensing and convection boiler

The difference between both options is as follows. In the case of convective devices, the heat carrier receives thermal energy only from the combustion of fuel - gas, and for condensing boilers, combustion products are also involved, the heat of which is also taken away. For this, additional exchangers are used - economizers.

But what is the difference between them for us, ordinary consumers?

• Firstly, we note that there is a very common opinion regarding convective boilers - the formation of condensate in them is extremely dangerous, since in addition to water it also contains acids. This is true and it means that for a heat exchanger not designed for such working conditions, nothing good will happen. There is only one way to overcome dew - to achieve the highest possible temperature of the heat exchanger, which, in other words, means: the temperature of the coolant flowing through the return pipeline must be at least 60 degrees. Therefore, convectors and wall-mounted radiators should be used as heating equipment with this kind of boilers. You can not use floor-mounted convectors, as well as yourself, because this will not lead to anything other than burning your legs.
• Condensing devices, on the other hand, literally need a low heat exchanger temperature. The standard heating scheme using boilers of this type is as follows: radiators are installed under the windows, a floor heating system is installed.

Convector

A characteristic difference between a gas convector is that heat is not transferred through a coolant - the heat source transfers it directly to the air of a private house. A coaxial pipe is used to remove the products of combustion of gas: gas goes out through its core, and clean air enters the room through its shell. Actually, this is how individual gas heating is often equipped in a private house if there is no gas main nearby.

What is the difference between a gas convector and similar devices? Let's get a look.

• To install or start a gas convector, you do not need to have special knowledge, you can do it all yourself.
• To install such devices do not need special wiring or a separate room. This is a significant advantage. In addition, such a convector will cost significantly less than a bimetallic radiator (which, moreover, needs to be wired).
• If the rooms are isolated, then each of them will require a separate convector.
• At the same time, the air is distributed unevenly, it will be hot under the ceiling, and cold below. Although, if you look, then underfloor heating systems do not have such disadvantages.

The principle of operation of gas boilers

Be that as it may, it is gas boilers that are most popular when installing a heating system. It is correct, because, as we have already said, it is very unprofitable to heat with gas cylinders, and cylinders are required for the operation of convectors. So, the principle of operation of boilers is almost the same as that of other devices intended for heating. The thermal energy released during combustion of the gas heats the coolant. The latter, in fact, is a source of heat, which, with the help of a pipeline system, enters the most remote parts of a private house. So, gas boilers consist of the following elements:

1. A furnace in which gas is burned.
2. Pipes required to connect to the system.
3. A burner that burns gas.
4. A pipeline that raises combustible gases.
5. , which removes the products of combustion of the fuel to the outside.

Next is the movement of the coolant. For this, there is another pipeline to which radiators are connected. This is another important detail of heating that needs to be given due attention, because they can have a variety of shapes and be made from a variety of materials.

In addition, gas heating in a private house also consists of a number of devices necessary to regulate the process. These are, for example, expansion tanks for accumulating excess fluid, a circulation pump, a temperature controller, an air outlet and various valves.

Do-it-yourself installation and installation

The heating system is perhaps the most important element of the house. Therefore, during its construction, it is necessary to pay great attention to each stage. Especially if all the work will be done by hand. And now - a phased technology for creating such a heating system.

Stage 1. We draw up a system project, which will include drawings and a working draft. It is extremely important here to calculate the required power of the gas boiler, all radiators and the circulation pump.

Stage 2. We calculate a preliminary estimate.

Stage 3. We buy all the necessary materials, parts and tools.

Stage 4. We install the heating system.

Stage 5. We fill it with coolant.

Stage 6. We are testing the system.

Stage 7. Actually, the operation of the heating system.

If you intend to do the installation of the heating system with your own hands, as we have discussed here, then you must agree with the moment that, in essence, it is nothing complicated. All you need is a few necessary tools, as well as skills in handling them. Of course, this is a delicate matter, therefore, of course, professionals who are aware of all the nuances of the issue should deal with it.

But if your decision is firm and unshakable, then this is a great opportunity to save money.

Important! Self-installation of the heating system is a great opportunity to save money, because the cost of equipment and materials is the same as the cost of their installation.

And the last thing you should know when working with the heating system. Everything related to gas should be done exclusively by employees of gas services. In this, first of all, we ourselves are interested, since this is for the purposes of our own security.
