What does an atmospheric gas boiler mean? Floor-standing gas boilers (atmospheric)

Next comes another German company Viessmann, which offers fairly high-quality products at average prices.

Positive sides:

• implemented in units Hi-tech, there are all the necessary sensors and temperature control systems;
• quiet operation of the equipment;
• high energy efficiency;
• ease of operation;
• easy installation of the device.

Despite all the positive aspects, the Viessmann boiler has a large number of cons. Almost all owners of boilers from this company complain about the excessive “gluttony” of the units, when it takes more than 150 cubic meters of gas to heat 50-60 square meters.

It is worth saying that the product is made in such a way that as soon as the warranty period expires, problems with the electronics begin. And if the boiler was not installed by a professional, then it may fail during the warranty period. Wherein service center does not always provide repairs under warranty, so we do not recommend giving preference to this company.

Another Italian brand Gazlux offers us its products. Positive aspects of branded boilers:

Let's move on to the cons:

• Although Gazlux is an Italian company, its products are manufactured in China, which seriously affects the quality;
• a warranty period of 2 years does not provide much confidence;
• the batteries run out very quickly, this is noted by all users of Gazlux boilers;
• the electronics may malfunction, causing the boiler to turn off, react incorrectly to the set temperature, or overheat (most often due to improper installation).

In general, when buying boilers from Gazlux, you get an average quality boiler at an adequate price. If you are counting on a small amount, then such equipment will come in handy.

Famous German company Bosch also produces wall-mounted atmospheric boilers, which deserve attention.

Product advantages:

• high quality materials that last a long time;
• quiet operation of the boiler even at high power;
• low price;
• implementation of all advanced technologies.

Disadvantages of the product:

• many components are manufactured by third parties;
• small the lineup;
• small number of service centers.

We can conclude that Bosch boilers are a good “anti-crisis” option in this market, having a low price and good practicality. However, it is worth remembering that the products are manufactured far outside Germany, which greatly affects the quality.

There are two common types of gas boilers - with an atmospheric burner and with a forced-air burner. Before choosing a boiler, it is important to decide what kind of burner it will have. We study the principle of operation, features of the device, advantages and disadvantages. What to prefer and why?

On the picture:

The important difference between gas boilers from each other is not appearance device, but in the gas burner device.

Atmospheric gas burner

Air supply is the same as in a conventional gas stove. They are also called " gas-burner for a boiler with an open combustion chamber." The burner in these devices is a tube with holes in the walls for gas outlet. The gas, mixing with the air in the room, is ignited by an electric fuse or piezoelectric element.

It differs from the gas burner in shape. Atmospheric gas burners for heating boilers are not round! The heat exchanger of such boilers is rectangular, and the burner follows this shape. This increases the heating efficiency, and therefore the performance and overall efficiency of the boiler. Atmospheric boilers are considered more simple models. They usually have relatively low power, however, such equipment is quite suitable for most country houses. More powerful units are not equipped with atmospheric burners for safety reasons.

Blast burner

WITH closed camera combustion. That is, such a gas burner for the boiler does not come into contact with the atmosphere in the boiler room. Air for the gas-air mixture is supplied forcibly - through special air channels using an electric fan - one or more.

On the picture:

The main elements of a boiler with a forced-air burner (view, internal diagram, burner design).

Advantages of forced-air burners

• High level of security. Unlike atmospheric burners, in forced-air burners, fuel combustion occurs in a closed, isolated space.
• More high performance boiler A boiler with such a burner has a special heat exchanger design. He is
  a double-walled barrel turned upside down: a burner torch burns inside it, and coolant circulates between the walls. Thus, heat extraction during gas combustion occurs not only directly above the burner, as in atmospheric analogues, but also to the side of the torch. Due to this, a larger volume of liquid is heated per unit time.
• Less sensitive to pressure changes in the gas pipeline. When fans are running, the pressure drop is lower established norm it is not as critical here as for atmospheric burners, which go out immediately.
• Easy to replace with a different type of burner. If necessary, the blower burner can be removed and replaced, for example, with a diesel one.

Disadvantages of forced-air burners

• Higher electricity consumption. An atmospheric gas burner, which does not require electric fans, consumes significantly less.
• Dependence on electricity. If there is no electricity, the burner does not work and the boiler turns off.
• Increased noise level during operation. It is caused by intense air movement in the ducts and the operation of fans. You can cope with this drawback using a sound-absorbing casing or simply by placing the boiler away from living quarters - in the attic, in the basement, in an extension, etc. In any case, although boiler manufacturers claim that their equipment can be installed anywhere, it still has no place in the bedroom.

Which type should I choose?

Atmospheric - it’s easier to choose an economy option. Among boilers with atmospheric burners, it is easier to find compact but reliable models with low power and two-stage flame settings. Simple atmospheric burners are in any case cheaper than forced-air burners. For small house This a good option. But do not forget that among atmospheric burners there are modern models with automatic settings.

Examples of gas boilers with atmospheric burner

Among the blowers there are more advanced and powerful models. As a rule, more expensive and powerful boilers are equipped with forced-air burners. Blowing devices are inferior in terms of noise and energy consumption, but gain somewhat in performance and safety. It is believed that blower burners have a wider range of settings.

The process of replacing the radiator in new apartment and the old one has a lot in common. First, this should be done by professionals. Secondly, this is the case when it is better not to look for something fundamentally new.

The mass production of the most iconic everyday items was preceded by years, and sometimes decades, of engineering research. We present to you the most useful home inventions in history.

The presence of a fireplace definitely makes the apartment more interesting architectural plan. And if you are only interested in the decorative side of the issue, it is not at all necessary to install a real fireplace.

When should you decorate your living room walls? Best of all – at the dirty stage construction work. Although you can do this later... But the range of possibilities in different cases will not be the same.

The choice of a heating boiler is largely determined by the ability to organize the supply of fuel on which it will operate. Gas, diesel, solid fuel, electric... Which boiler to choose?

To understand which boiler is better, atmospheric or turbocharged, use it for a specific heating system you need to understand some design features and operating principles of the devices.

An atmospheric gas boiler can be wall-mounted or floor-mounted, as well as single-circuit, intended only for working with the home heating system, or double-circuit (with an additional coil) - for heating water.

In such a boiler, an open-type combustion chamber is installed, that is, air is taken in directly, in a natural way. It is precisely because of this feature that atmospheric installations are located in special boiler rooms, which can be equipped in a private country house, as a rule, does not pose much of a problem. But if it is planned to install a gas boiler in an apartment, then this factor becomes not only a disadvantage, but also an obstacle.

In addition, to remove combustion products, a traditional chimney with access to the roof of the building is required, which, again, is quite feasible in a private house, but difficult in an apartment building. Apartments may be exceptions old building with existing chimneys, which still need to be modernized over the years, but the percentage of such houses is small. If you plan to install an atmospheric boiler in a country house, then in addition to boiler room equipment, you will need initial stage construction, design and install a chimney taking into account all the rules and regulations. It is imperative that the furnace room be equipped with effective system ventilation, which will provide the flow of oxygen necessary for the combustion process.

Operating principle of an atmospheric boiler

An important difference between an atmospheric boiler and a turbocharged one is the type of burner. In the first model, it is a set of nozzles, the diameter of which is small enough to ensure gas exits at a certain pressure. It also regulates the amount of incoming oxygen, and, accordingly, the intensity of combustion.

The principle of operation is based on the fact that the burner heats the heat exchanger, which can be made of cast iron or steel, thus heating water or other coolant. And the combustion process is ensured and supported by mixing the gas mixture with air before supplying it to the burner nozzles. The latter, based on the principle of mixing, can be with partial or complete mixing, the operating efficiency and efficiency of which are slightly higher, but it is important to note that they are almost never found on the domestic market.

All of the above factors can be considered either features or disadvantages of the equipment, depending on the specific situation, but atmospheric boilers have two important and undeniable advantages, which often sway the consumer in their direction. First of all, this is the fact that most models of this type are non-volatile, and therefore preferable in operation in the presence of constant interruptions or unstable power supply. The second advantage is the low price (in comparison with turbocharged models of comparable power) of the equipment. It is important to note the safety of operation, for which the traction sensor is responsible, and which is equipped in almost all models of this type.

An atmospheric boiler is a heating equipment, the feature of which is a burner built into the body. This device is characterized by low noise, affordable cost and high power(up to 150 kW). GC "EKVOLS" supplies floor-mounted atmospheric gas boilers, among which there is sure to be a suitable option for heating a room of any size.

Range of boiler equipment with atmospheric burners

The models we present are very diverse. Thanks to this, you have the opportunity to purchase an atmospheric gas boiler for heating as a summer house or country house, and a large object with total area up to 29,000 m². The heat exchanger in such equipment can be cast iron or steel. There are floor-standing atmospheric boilers that are volatile (require connection to the electrical network) and non-volatile (do not use electric current). The model range is also divided into single-circuit and double-circuit installations. The first type works only for heating. A gas boiler with a double-circuit atmospheric burner is perfect for those who want to organize not only efficient heating, but also an autonomous supply of hot water.
