Gas boiler double-circuit floor chimney. Floor-standing chimney gas boilers: general idea, characteristics and features of choice. From the type of completeness of fuel use



The constant rise in gas prices has made economy heating equipment, one of the main selection criteria. Coaxial gas boiler, has a high efficiency up to 109%. Due to the special design of the combustion chamber and certain operating nuances, it is possible to install coaxial boiler equipment in an apartment high-rise building. The boiler is suitable for connection to any type of heating system.

Why are boilers called coaxial

This name appeared due to the peculiarities of the smoke exhaust system. A coaxial exhaust structure is mounted in the boiler device. The chimney performs two important functions at once:



The boilers got their name due to the special design of the combined coaxial air supply and removal of combustion products, but the difference in the principle of operation (compared to the classic versions of heating equipment) is not only this.

The principle of operation of coaxial boilers

coaxial gas boilers with a closed combustion chamber, have a more accurate name - "condensation", reflecting the basic principle of operation. This equipment has a high efficiency of 108%, compared to classical heat generators, 92-96%. The structural differences are:

The difference between coaxial boilers from others

There are several differences between a coaxial boiler and classic atmospheric versions of heating equipment.
  1. Closed combustion chamber.
  2. High efficiency achieved through maximum extraction of thermal energy in the gas combustion process.
  3. Smaller room volume required for the installation of a gas coaxial boiler.

Boiler equipment can be placed in a room from 8 m². Installation is allowed, (provided that the current SNiP allow). Boilers can be built into furniture or a special niche.

Coaxial heating equipment has several disadvantages associated with its operation. The disadvantages of coaxial boilers are:

  • Coaxial models are recommended for connection to low temperature heating systems. It is under such conditions that the efficiency of the device will reach 108-109%. In the harsh Russian winter, it is not always advisable to install a coaxial boiler.
  • Cost - used in the design of the boiler stainless steel heat exchanger, automation, condensation unit and many other modules that increase the cost of equipment. On average, the price of a boiler is 2-3 times higher than that of a classic heat generator.

Installation of a gas boiler with a coaxial outlet

Heating system device with coaxial gas boiler, does not have a complex scheme. Installation of all nodes is carried out within 2-3 hours.

The general device requirements are:

  • Chimney connection- the pipe is installed in accordance with current SNiP and manufacturer's recommendations. To provide good performance draft, it is forbidden to use more than two turning angles along the entire length of the flue system. total length vertical chimney, should not exceed 3 m.
  • Minimum installation height– distance is calculated by outer wall building. The requirements regulate that the head should be located at least 1-1.5 m above the ground.
  • Condensate drainage system– during operation, the boiler uses targeted condensate formation. Waste condensate will need to be diverted from a special container to the sewer.
  • The optimal conditions for installing a coaxial boiler are to install the equipment on the wall through which the chimney will be led out of the building. To provide the best performance draft, the length of the chimney should be within 1-1.5 m.
  • You can avoid icing by installing an insulated, as well as, condensate trap.

Models of boilers with a coaxial chimney

To facilitate the choice, all presented models of heating equipment are divided into three categories according to the following criteria:
  • Type of installation - the consumer is offered floor-standing coaxial gas heating boilers and their wall-mounted counterparts. Stationary models have great performance, but are inconvenient in installation and subsequent operation.
    Wall-mounted coaxial gas heating boilers are more popular due to their compact size and availability a large number various functions.
  • Number of heat exchangers- a coaxial double-circuit gas boiler, works for heating hot water and heating systems. Modern models, have a built-in buffer capacity, providing almost instantaneous supply of hot water to the consumer.
    A coaxial single-circuit gas boiler, designed exclusively for heating, but has a higher power compared to a double-circuit analogue. If desired, after a slight modification, an indirect heating boiler is connected to the heat generator with one heat exchanger.
  • Manufacturer - popular models are offered by the following companies:

In the classical sense, any heating system is a device that processes fuel (gas, wood, peat, etc.). As a result of fuel combustion, the so-called combustion results are released, which must be removed from the furnaces using a chimney system.

But relatively recently, gas heating boilers have appeared that do not require a bulky chimney. And as a result, labor-intensive work on the installation of a chimney, the passage of storey ceilings and roofs, isolation of passage places and other works is not needed. At the same time, the combustion products have a high temperature at the outlet of the boiler, and as a result, thermal insulation of the chimney, insulation of floor passages and roofs is required.

Do not require a chimney in its classical sense. The combustion products, of course, need to be removed, but they are cold and the chimney can be made from simple pipes PVC. Also, a strict verticality of the chimney is not required to create draft. In gas boilers without a chimney, you can make as many turns of the chimney as you want.

How gas boilers work without a chimney

I want to get better right now. A gas boiler without a chimney means a boiler without a chimney in its classical sense: with draft and hot air. In these boilers, combustion products are discharged cold through a coaxial chimney.

What is a coaxial chimney

A coaxial chimney is two plastic pipes, one in one. Combustion products are removed through the inner pipe, and air is taken from the street through the layer between the pipes.

This design allows you to cool the products of combustion and make a chimney from plastic pipes. Cooling occurs with air coming from the street.

Features of installing a coaxial chimney

The coaxial chimney is not discharged through the roof, you can safely turn the chimney and lead it through the wall.

Important! There should be no windows on the wall where the coaxial chimney pipe exits. After all, the combustion products remain dangerous to humans and, by placing such a chimney under the window, carries the threat of poisoning through the window.

In conclusion, I note that gas boilers without a chimney, or rather with coaxial chimney, can be both floor and wall-mounted. Brands: Daewoo, Olympia, Rinnai.

Regulations:

  • SNiPII-35-76 "Boiler plants";
  • SNiP 2.04.05 "Device of smoke and ventilation ducts".

Flueless gas boilers are great solution in cases where it is necessary to install a heating device in a small room. They will also help to get out of a situation where it is impossible to equip housing with a stationary chimney. Such a heating system has a special smoke exhaust design, the main advantage of which lies in its compactness and location. It is located directly above the device.

Equipment device

Chimneyless boilers are designed to perform the same function as conventional ones. They are able to heat the room and cook hot water, but their combustion chamber is arranged somewhat differently and, in principle, works. If a conventional gas apparatus operates due to a chimney and draft, then this model takes in air and exhausts exhaust gases through a coaxial pipe. Equipment of this type can be connected to the system from one or two sides. In this case, gases are discharged along the inside of the coaxial pipe, and outdoor system draws air into the boiler.

The design of the chimney is very convenient to use, besides it is fireproof. high temperature combustion products are extinguished by cold air coming from the street. Another plus is that the boiler is undemanding to the presence of draft and air flow - all these operations are performed forcibly due to the fan built into the equipment.

Types of boilers

Chimneyless boilers can be wall and floor. The most effective gas boilers are wall-mounted, single-circuit, chimneyless. This model performs its main function not only by burning gas, but also by using the residual heat of the condensate obtained from the vapors of the air discharged into the atmosphere. Particularly good results can be achieved with low-temperature operation, in particular if a certain length heating system made according to the principle of underfloor heating. Since the temperature of the heat carrier in the "warm floors" system is only 45-50 ° C, this allows water vapor to condense more strongly in the exhaust gases.

Condensing units have the highest possible efficiency, environmental friendliness and minimum consumption fuel. The disadvantage of such equipment is the need for a special removal of the condensate obtained during operation. Such moisture must not be drained into surface water or soil, as it is saturated with acids and can disrupt bacterial microflora. For wall-mounted condensing boilers, the chimney must be made only of high-quality plastic, resistant to acid fumes.

If it is impossible to install a classic vertical chimney, chimneyless gas boilers are used for heating. For such heating equipment, a ventilated separate room for natural traction.

Despite the name "chimneyless", there is a chimney in such boilers. Its role is played by a compact coaxial pipe, which provides traction and removal of smoke masses from the combustion chamber.

External outlet of the coaxial chimney

The design and principle of operation of chimney-free boiler equipment.

Chimneyless, like classic gas boilers, operate in heating mode - single-circuit, and even like water heaters (DHW) - double-circuit.

The salient feature of the design is closed chamber combustion. The burner, through which the gas heats the water in the system, is located in a sealed chamber. Thus carbon monoxide, soot and smoke from fuel combustion do not penetrate into the room, and the efficiency of the boiler increases.

Oxygenated combustion air enters the closed chamber through the external chimney block. The air heated by the burner element heats the copper circuit through which the coolant flows. Then the "exhaust" air, together with the products of combustion of the fuel, exits through indoor unit coaxial pipe.


Scheme of operation of a floor coaxial boiler

Coaxial chimney is simple to implement. These are two coaxial pipes of different diameters, fastened together. Thus, the heated gas waste is cooled by the air entering the chamber, making the boiler fireproof and environmentally friendly for the residents of the house. Cooling the products of combustion, the air enters the combustion chamber already heated, which saves energy.

High-power gas boilers are equipped with deflectors to prevent insufficient draft, which increase the air flow by one and a half times. If there is a possibility of wind blowing, a special wind protection block is installed at the pipe outlet.

Features of the installation of gas boilers with a coaxial chimney.

Floor standing chimney boilers for autonomous systems heating systems are installed in small buildings and in many apartment buildings or industrial premises.

Chimneyless gas boilers are installed on a special stand. If the boiler is controlled electronic board, then it is connected to electricity according to the rules for installing electric and gas equipment by specialists.

They are included in the heating system and gas mains in the same way as chimney gas boilers. The difference is the installation of a coaxial chimney.


Installation diagram of a horizontal coaxial chimney

Requirements for installing a coaxial pipe as a chimney:

  1. The outlet of the chimney to the street passes through the wall horizontally. The length of this pipe section is no more than 1 meter.
  2. The chimney is horizontal, but if horizontal chimney is not possible, a vertical chimney is used. The length of the vertical part of such a chimney is about 3 meters.
  3. The outer part of the pipe is located no lower than 2 meters from the ground.
  4. Distance from pipe to window or doorways is at least half a metre.
  5. You can not place the outlet of the pipe under the window.
  6. To prevent the accumulation of condensate liquid, it is installed at an angle of 3-5 degrees.
  7. Observe the diameters of the pipes of the coaxial chimney and their ratio for fire safety.
  8. The hole drilled in the wall for the pipe is lined with a heater made of non-flammable material.

Compliance with these requirements will make the operation of the boiler safe and efficient.

Chimneyless boilers - their pros and cons of operation.

The advantage of underfloor heaters equipped with a coaxial pipe is installation in the living room. To fit the boilers into the interior, the decoration of the walls and the junction of the chimney with the wall is selected.

You can learn more about coaxial chimneys and their use for gas boilers in the video below.


Coaxial boiler in the interior of the apartment

In addition, other advantages:

  • simplicity and low cost installation;
  • there is no need to install supply and exhaust ventilation;
  • high power units of such a design that they heat large areas;
  • some gas models equipped with convection holes, which makes it possible to heat the room without a radiator;
  • long service life.

The disadvantages of coaxial boilers are in the smoke extraction system. The length of the smoke exhaust pipe is not more than 5 meters. During frosts, chimneyless boilers operate at high power, due to which more condensate forms in the coaxial pipe, which freezes and blocks the air supply and smoke removal. The blowing out of the chimney occurs if it is not equipped with a wind protection.

Floor-standing gas boilers with a coaxial chimney: price and types

When heating large-sized premises, fuel consumption and price are of particular importance. Currently one of the most economical options generators are floor standing gas boilers with a coaxial chimney. With their help, it is possible to provide heating of premises of any type and area, heating of water for household and other needs.

The principle of operation of a floor gas boiler

The fuel for such a generator is most often natural or liquefied methane or propane-butane. In the process of its combustion, a huge amount of energy is generated, which the generator redirects to the coolant.
The combustion chamber contains an element that ignites the fuel. All boilers of this type have a fuse that shuts off the gas supply when the ignition is turned off.


Gas boilers are divided into two types - floor and wall. Wall-mounted generators are more compact, due to which its power is reduced. Such boilers are suitable for periodic heating of small premises, such as greenhouses, small industrial buildings, Living spaces.


Floor gas boilers are characterized by increased power and a high coefficient useful action. Such parameters are achieved primarily due to the larger combustion chamber and the body as a whole.


Floor thermal generators are used for heating or providing buckwheat with water industrial premises or residential buildings of a large area.

The principle of operation of a coaxial chimney

Any boilers that function by burning fuel produce a large amount of bad choices in atmosphere. The operation of such a boiler is impossible without the arrangement of a chimney pipe. At the moment, floor-standing gas boilers with a coaxial chimney are especially popular. This type of chimney has a double-circuit design, i.e. consists of two pipes, the smaller of which is inside the larger one. It provides two functions at once.
Through inner tube with a smaller diameter smoke and other products of combustion exit the boiler. A large chimney provides a constant supply of air for the combustion of the fuel. Thanks to such a chimney, the efficiency of the generator increases by 10-12%, the supply of air to the boiler and the removal of combustion products are localized in one place.


Both of these advantages are possible due to the transfer of thermal energy from the air flow from the boiler to air flow from the street. Heated air from the street increases the combustion time of a unit of fuel, thereby reducing its consumption. Combustion products, passing the way from the generator to the street, lower their temperature by an average of 10°C. Thereby outer part flue pipe can be made on the side of the room.

Types of outdoor gas boilers with a coaxial chimney

Gas floor boiler with a coaxial chimney can be convection and condensation. The principle of such division is determined by the completeness of the use of fuel.
Convection gas boilers are very common due to the fact that the average cost of such equipment is on average 20-30% cheaper than the second option. The boiler works at the expense of the lower heat of combustion. The term lower calorific value refers to the amount of infrared energy that a unit of fuel emits without taking into account additional factors. The design of such a generator ensures that condensation does not form on the walls of all its parts.
Condensing boilers, in addition to the energy of fuel combustion, use the heat that forms during the evaporation of condensate. The design provides for areas with a dew point - the temperature difference at which water in gaseous state converted to condensate. The body of such a boiler is much larger than a convection one, because in addition to the main parts, an economizer is provided in its design - a generator element made of straight or corrugated cast iron pipes on the walls of which condensation accumulates. Fuel consumption when using this element is noticeably reduced.


The price of a floor-standing gas boiler with a coaxial chimney
As a rule, the chimney and boiler are purchased separately. average cost chimney, regardless of the configuration and the manufacturer's company, varies within 4 thousand rubles. Quite often, large companies selling heating boilers arrange promotions during which the chimney acts as a gift to the generator.
The generator itself will cost about 20-30 thousand rubles, depending on the power.

Fuel consumption of a floor-standing gas boiler with a coaxial chimney

For heating 10 sq. meter area requires 1 kW of power. Based on these data, it can be revealed that a generator with a capacity of 10 kW is enough to heat a room with an area of ​​​​100 square meters.

Fuel consumption depending on the power of the generator can be seen in the following table.


Based on these data, you can calculate how much fuel is needed to heat the room per month.

Floor-standing gas boilers with a coaxial chimney - design features and practical application

The very word "coaxial" means "one in the other." For a chimney, this is the principle of "pipe in pipe". Such a chimney for a gas boiler is a double-circuit design - a pipe with a smaller diameter is placed in a pipe with a larger diameter. Inside, these pipes are interconnected using special jumpers that prevent their contact.

It looks like a coaxial device

To not bother looking essential elements systems gas heating: the corresponding pipes for the chimney and extensions, it is more expedient to purchase the whole set as a whole. Firstly, this should save a lot of time, and secondly, this kind of chimney, called coaxial, equipped with steel or plastic pipes, will surely turn out to be safer and more durable, because the details, ranging from tees, bends and ending with transitions and stainless steel flanges in the chimney, should correspond to each other as much as possible.

If you are not quite sure what kind of chimney pipe is required for your heating system, whether it be a gas boiler, fireplace, stove or column, it would probably be better to seek help from specialists. Those, having made an inspection and measurement of the premises, will pick up best option. And, importantly, they will help with delivery and installation (the services of such specialists, by the way, are provided in almost every store specializing in chimneys for gas boilers and related heating equipment).

In order for any heat generator (with the possible exception of an electric one) to work stably, the system must provide for the removal of gases generated during the combustion of fuel. In addition, as everyone knows, combustion itself (as a process) is possible only when a continuous sufficient supply of air is provided. Otherwise, we have incomplete combustion of fuel. How a coaxial chimney for a gas boiler really differs from a conventional chimney, we will consider in the article.

Installation of chimneys of this type is carried out, as a rule, with boilers that have a closed combustion chamber, these are usually floor (or wall) type devices located on any of the floors. The direction of the chimney is determined individually in each individual situation. The chimney is located both in a vertical and horizontal or inclined plane.

Note! For fire safety purposes, the chimney opening must be at least one and a half meters higher than the boiler. The hole itself should slightly exceed the diameter of the actual pipe. When bringing it out, the pipe must be slightly tilted (angle more than 3 degrees) to ensure the outflow of condensate. To prevent possible blockages of the air duct, the outlet is located no closer than one and a half meters from the ground surface.

How does a coaxial chimney look like indoors

in boilers with forced circulation always use a horizontally located chimney. If there is no (or perhaps difficult) possibility for the pipe to exit through one of the walls directly to the street (the reason may be the insufficient width of the street or closely spaced windows), then a vertical version of the coaxial chimney is used.

During installation, the so-called. coaxial not only elbows, but also flanges, clamps, adapters. In order to avoid violating the design of the room, you can buy decorative overlays, picking them up in style general interior. If it is necessary to lengthen the pipe, it is worth using only clamps, without using other improvised means such as sealants and adhesives.

This is that the air for an efficient combustion process is taken from outside (and not from the room). A simple stove takes oxygen from the room, which requires frequent ventilation. The principle of operation of coaxial chimneys is somewhat different - here combustion products enter the inner pipe, but the outer one serves as an influx of fresh air.

What does it give

Such a design immediately solves a number of problems inherent in conventional heating appliances and chimneys. We let you evaluate it.
The air coming from the outside comes already hot, because it is heated by the inner pipe due to the very hot combustion products passing through the pipe. This greatly reduces heat loss, resulting in both increasing the efficiency of the entire system;
Increased efficiency will lead to complete combustion natural gas. As a result, particles of unburned fuel will not be emitted into the atmosphere, which will increase the environmental friendliness of the boiler;
Of great importance is the fact that the pipe inside, when transferring part of its heat to the outer pipe, gives off part of the heat and cools down. This moment partially reduces the fire hazard;
All heating processes from the very moment of air intake to the removal of combustion products are closed - in the combustion chamber. Accordingly, there is no need to worry about additional ventilation, because neither smoke nor carbon monoxide should enter the room;
The presence of a wide variety in pipe sizes, this applies to both external and internal ones, makes it possible to choose a coaxial chimney for a gas boiler of almost any power;
Compactness allows you to save considerable space indoors;
Those who have dealt with such equipment note the ease of installation (this applies to both the boiler itself and the coaxial chimney). They also talk about the relatively easy operation and service of such a heating system.
Naturally, if frank mistakes are made in the installation of a coaxial chimney, you can not get its benefits. This also applies to safety and environmental friendliness. So the question of correct installation is very important.

  1. Installation of a boiler with a coaxial outlet

The constant rise in gas prices has made the efficiency of heating equipment one of the main selection criteria. Coaxial gas boiler, has a high efficiency up to 109%. Due to the special design of the combustion chamber and certain nuances of operation, it is possible to install coaxial-type boiler equipment in an apartment in a multi-storey building. The boiler is suitable for connection to any type of heating system.

Why are boilers called coaxial

This name appeared due to the peculiarities of the smoke exhaust system. A coaxial exhaust structure is mounted in the boiler device. The chimney performs two important functions at once:

  • Removal of combustion products - the design of the chimney is a simple device, like a "pipe in a pipe". Through the internal cavity, combustion products are removed.
  • The air supply to the burner device - the intake of air masses occurs through an external pipe. The air entering the boiler surrounds the inner chimney pipe, heated by the exhaust products of combustion, is preheated before entering the burner, which increases heat transfer.

The boilers got their name due to the special design of the combined coaxial air supply and removal of combustion products, but the difference in the principle of operation (compared to the classic versions of heating equipment) is not only this.

The principle of operation of coaxial boilers

Coaxial gas boilers with a closed combustion chamber have a more accurate name - "condensing", reflecting the basic principle of operation. This equipment has a high efficiency of 108%, compared to classical heat generators, 92-96%. The structural differences are:

Air intake and exhaust of combustion products is carried out through a horizontal chimney. This feature design, allows you to reduce the requirements for the room where the gas boiler will be installed.
  • The use of heat from the exhaust products of combustion - in the heated air, there is a large amount of heat. The principle of operation of the boiler is based on improved accumulation of thermal energy from combustion products. Heat is extracted by the method of purposeful condensation of steam particles on the surface of a special heat exchanger.

The difference between coaxial boilers from others

There are several differences between a coaxial boiler and classic atmospheric versions of heating equipment.

  1. Closed combustion chamber.
  2. High efficiency achieved through maximum extraction of thermal energy in the gas combustion process.
  3. Smaller room volume required for the installation of a gas coaxial boiler.

Boiler equipment can be placed in a room from 8 m². Allowed installation in the kitchen. bathroom (provided that the current SNiP allow). Boilers can be built into furniture or a special niche.

Models of boilers with a coaxial chimney

To facilitate the choice, all presented models of heating equipment are divided into three categories according to the following criteria:

  • Type of installation - the consumer is offered floor-standing coaxial gas heating boilers and their wall-mounted counterparts. Stationary models have great performance, but are inconvenient in installation and subsequent operation.
    Wall-mounted coaxial gas heating boilers are more popular due to their compact size and the presence of a large number of various functions.

  • Manufacturer - popular models are offered by the following companies: Buderus, Viessmann, De Dietrich, Baxi, Vaillant, Ferroli, Navien, Rinnai.

The standard of quality is the product German manufacturers. French equipment has a simpler and more comfortable control, and Italian products are distinguished by an acceptable cost and at the same time wide functionality.

Boilers of the latest generation are equipped with weather-dependent automation, which increased efficiency and facilitated operation.

If your apartment or private house does not have a traditional chimney, and you need to heat your home, then the best option there will be a purchase of a parapet gas boiler.

Chimneyless boilers: principle of operation

The main feature that parapet boilers (or, more simply, chimneyless boilers) have is a closed combustion chamber, the air into which does not come from the room (as in conventional boilers), but directly from the street. Combustion products are also removed directly to the street. This is especially valuable in small spaces.

Air intake in parapet boilers and the removal of combustion products occurs through outer wall dwellings. To do this, use a special coaxial horizontal chimney. It consists of two small pipes, one of which fits into the other. Air enters the chamber through the outer pipe, and combustion products are removed through the inner pipe.

Hot water from a parapet boiler

Parapet coppers are made one - and two-functional. Dual-functional boilers are distinguished by the fact that a flowing tubular water heater is mounted in the boiler body. It is made of copper, as copper has a high thermal conductivity. The ability to get hot water with the help of a boiler makes a parapet boiler practically ideal option for home use.

Heat possible without batteries

Another important advantage of parapet gas boilers is the presence of convection holes in the casing. This gives heating to the room in which the boiler is located, without installing special radiators in it.

Where to install a parapet boiler

Also, due to the fact that the parapet gas boiler does not need to be connected to the chimney, it can be mounted absolutely anywhere. It is very convenient that, most often, boilers of this type are made in the shape of a rectangle.

There should not be any special problems with the connection either: chimneyless boilers come in right and left versions. In boilers with right-hand execution, automation is located with right side boiler, and the pipes for connecting the boiler to the heating and water supply system are on the left. In boilers with left-hand execution, the opposite is true.
