What can be cooked from squid: quick and tasty

If, when designing a heating system, the owner prioritizes such criteria as efficiency, safety and practicality, then he should consider parapet gas boilers, which can be used as basic devices for heating the coolant in the circuit. Unlike traditional gas-fired heaters with bulky dimensions, parapet models have a neat compact rectangular body and a built-in chimney. These design differences lead to ease of installation, high maintainability, ease of use and availability. Maintenance boilers.

Before buying a parapet gas boiler, the consumer should familiarize himself with the specifics of its operation. The main distinguishing feature of such devices is energy independence, ease of removal of combustion products through a coaxial chimney, and the use of a closed combustion chamber. This design allowed the developers to combine the strengths of traditional and environmentally friendly convectors in one device. Thus, the parapet gas boiler, which has a positive feedback, is a safe and practical heater that can be used for efficient heating premises with a small area.

The boiler device is represented by the following elements:

At first glance, the device of a parapet boiler differs from the design of a traditional analogue only by the presence of an integrated vertical flue, with the help of which exhaust gases are discharged outside and air is taken from the street to prepare an optimal gas-air mixture. If we approach the analysis design features parapet boiler in more detail, the following features can be noted:

Two-circuit parapet gas boilers have a slightly modified design, prices for which start at two hundred dollars. The device of these models is characterized by the presence of an additional circuit. It is involved in the process of supplying hot water for domestic needs. Passing along the additional circuit, the running water is heated to the temperature set by the thermostat settings. It can be used by residents by opening the corresponding tap in the bathroom or kitchen. Such a device improves the functionality of the boiler and expands the scope of its application.

Principle of operation

From model to model, a parapet gas boiler, reviews about which can be found on the manufacturers' website, may differ appearance, cost and performance. However, the principle of operation is similar for most models. It can be schematically represented in the form of several stages.

At the first stage, a pilot burner is ignited using a piezo ignition system, and then gas is supplied to the main burner.

In the process of combustion, the gases heat the walls of the heat exchanger, through which the coolant circulates. After the coolant is heated to a certain temperature, a signal is given to stop the operation of the boiler using the automation and the burner goes out. Further, the operation of the boiler is controlled by a system of temperature sensors and thermostats that give commands to turn the device on and off when the temperature in the room changes.

The lineup

Today, parapet boiler models are presented on the market with a wide variety of models from various manufacturers.

In the product line, you can find boilers with various capacities, which are designed to heat houses and apartments.

Also, boilers are classified according to the type of installation, the number of circuits and performance characteristics. It depends on these parameters how much a gas boiler costs and how it will recommend itself in the heating system. Discerning buyers looking to find the best way heater, before choosing a particular model, it is worthwhile to study products from the main manufacturers operating on the market for heating equipment for the home.

Advantages of the parapet boiler "Helios":

Boilers from the Luch brand - functionality and reliability

The Ray parapet gas boiler is produced in Taganrog. This boiler differs from analogs in a compact body, a simple installation procedure and an inexpensive price. Various boiler models can be used to heat houses ranging from 80 to 180 squares. When choosing the power of the boiler, it should be borne in mind that the device should not work for wear and tear. Experts recommend to select the power of the device in accordance with the requirements of the heating scheme, developed by competent heating engineers.

The specifics of the work of parapet models from the Luch brand is represented by the following list:

Not all owners imagine what a parapet gas boiler is, although many have been using it for a long time. This is a non-volatile unit, without being connected to the chimney of a house or apartment. The gas parapet boiler removes the combustion products through a coaxial chimney through the wall of the building. The presence of a closed combustion chamber of fuel (gas) makes possible installation such units in small rooms, since oxygen is not taken from the room for the combustion process.

Advantages and features of parapet units

The main advantage of the equipment is its compactness: a parapet boiler, running on gas, can easily fit in the kitchen under the windowsill or in any other room, since during operation it does not consume oxygen from the room and does not pose a danger to residents. A coaxial chimney is a reliable and safe smoke exhaust system, which also offers a choice in favor of such equipment.

The correct choice of a product should be based on the following parameters (except for consumer reviews and catalogs in selling companies):

1. Installation technology: the parapet boiler is made for mounting on walls and on the floor, there are also left-side and right-side models;
2. The gas parapet boiler can be equipped with one or two circuits. One circuit is for heating only, the second circuit is for DHW;
3. Also, parapet boilers can be volatile (with an automatic monitoring, regulation and control system) and non-volatile (with or without manual adjustment).

The heat output of the parapet boilers varies between 15 kW-40 kW for a unit with one circuit. If the installation of parapet equipment with two water heating circuits is chosen, then the capacity for heating water for domestic needs should be added to the nominal power. For example, parapet boilers with a capacity of 12 kW -15 kW easily heat up the volume of water up to 180 l / h, and this, according to the standards, is four points of water intake (taps, toilets, mixers, showers, etc.).

1. The single-circuit unit has a standard heat exchanger (jacket) of a plate design, which speeds up the process of heat exchange between the gas burner and the working fluid of the heating system. Shirt material - thick 3mm steel.
2. Double-circuit gas parapet boilers include, in addition to the heat exchanger, a copper or brass coil for hot water supply, in which water is heated only by the flow method. If the DHW capacity is increased by means of an additional hot water tank, then such a boiler will no longer be possible to install in the kitchen.

Also, in addition to wall and floor models, there are products with a difference in installation: with left-hand connection gas pipe, a circuit of hot water supply and heating, and with a right-hand one. This convenience should not be overlooked when choosing a boiler for an apartment or a house. The dimensions of the unit are determined by its capacity and the number of water heating circuits. For example, if a boiler has one circuit, then its dimensions will be smaller than that of a double-circuit one.

Parapet equipment device

The body of the unit is painted with powder fire-resistant anti-corrosion paint, which for working conditions in the kitchen saves from the action of high humidity and rusting of the metal. The thick 3 mm body (not a casing, but the body of the working unit) is resistant to mechanical stress.

The equipment is simple, but effective:

1. Thick-walled metal case;
2. Closed combustion chamber;
3. Gas burner and ignition;
4. Coaxial type chimney;
5. Metal jacket (heat exchanger), in the presence of a second circuit - copper or brass coil.

Automatic control and management group:

1. Thermometer;
2. Thermocouple (thermal sensor);
3. Air draft sensor.

Self-installation parapet equipment is impossible - this must be done by representatives of the gas service after the owner has received the appropriate permits. The unit can be mounted anywhere. The main thing is that the boiler stands next to the wall - this way the coaxial chimney will be shorter and safer. The main advantage of parapet gas boilers is a closed combustion chamber and a coaxial chimney that can be installed anywhere in the room. These two nodes allow the boiler anywhere in the room without fear for the safety and health of the residents, since neither the sealed closed combustion chamber nor the autonomous chimney allows toxic gases to enter the atmosphere of the living quarters.

The chimney of a coaxial device is metal structure from two pipes of different diameters. A pipe of a smaller diameter is inserted into a pipe of a larger diameter, and the free space between them serves for intake of air entering the combustion chamber. Combustion products are discharged through a pipe with a smaller diameter.

Self-installation of the parapet gas boiler do it yourself is strictly prohibited. Licensed professionals must be engaged in the installation and commissioning of gas equipment, and only employees of the regional gas service have the right to connect the parapet gas boiler to the gas main.

The process of installing gas parapet equipment is similar to installing a gas convector: the smoke exhaust system of a coaxial chimney is brought out through the wall of a house or apartment to the street, while the end of the pipe must be protected by a windproof cap so that a burst strong wind did not extinguish the wick. Then, in the same way, the pipes for gas water, heating and hot water supply circuits are installed.

How the boiler works

The non-volatile gas boiler is equipped with a piezoelectric ignition - for this, there is a special button on its body. The wick ignites and ignites the gas burner.

When installed in the equipment of the automation system, the boiler is ignited in automatic mode, depending on the readings of the sensors. More reliable, versatile and easy to operate - non-volatile models of gas parapet boilers, therefore they are more popular in the domestic market.

The parapet gas equipment works according to a simple and understandable technology: the gas burner of the boiler is ignited from the wick and heats the heat exchanger, through which, with the help of circulation pump or the working fluid moves by natural current. The gas will burn until the water temperature in the heating system reaches the level set by manual or automatic regulators, after which the gas is automatically turned off by closing the gas valve at the boiler inlet. The wick is working at this time, and is ready at any time to ignite the burner again, as soon as the water temperature in the system drops below the set parameters, and the command for heating is received.

The gas boiler safety group consists of the following units and elements:

1. Thermocouple, which is installed directly in the flame of the burner;
2. The traction control sensor is installed at the outlet of the combustion chamber;
3. Thermal sensor and thermometer.

Why do you need a thermocouple: it generates a small voltage under the influence of heat from the burner flame, which controls the position of the gas valve. If the combustion in the chamber stops, then the voltage in the thermocouple disappears, and the valve automatically closes, blocking the flow of gas into the boiler.

In the absence of air draft in the boiler, the heat exchanger quickly heats up to + 65 ° C and above. The signal from the heat exchanger plate goes to the gas supply valve, it closes and combustion ends. This is how the safety group of a non-volatile boiler works. If the boiler is connected to the mains, then all processes are controlled by the control and automation system.

A thermometer paired with a temperature sensor (thermostat) serves to protect the parapet boiler from high temperatures. The mechanism works like this: when the thermometer detects a critically high temperature of the working fluid in the system, it sends a command to the thermostat, which closes the gas supply to the boiler burner.

Wall-mounted parapet gas equipment is even more in demand than conventional floor-standing boilers with a chimney equipped in a building due to its versatility and undemanding operation parameters. For example, conventional wall-mounted units are sensitive to changes in the gas pressure in the mains, because of this, scale appears on the boiler jacket more often, in addition, such units require an uninterrupted supply of electricity.

Parapet gas boilers are less sensitive to pressure drops in the gas supply pipes, and non-volatile equipment does not need to be connected to the mains at all. The coaxial type chimney is undemanding to the installation conditions: it can be installed both horizontally and vertically, which gives room for a more convenient positioning of the boiler in small rooms.

Problems and solutions with parapet gas equipment

Despite all the provided safety measures and control over the operation of gas equipment, parapet units can create problems:

1. Camera closed combustion made of two elements connected to each other polymeric materials... If the maintenance schedule is not followed, the polymer layer may begin to deteriorate. , which will lead to the leakage of toxic combustion products into living quarters;
2. The material of coaxial chimneys in cheap models of parapet units can be made of black steel, which burns out quickly. Remember one mandatory requirement of GOST: in all models of gas parapet boilers, the coaxial chimney must be made only of of stainless steel... If the pipes are made of ordinary steel, then soot and condensate quickly accumulate on them, the air draft slows down, corrosion corrodes the metal, all toxins have the ability to freely enter the room. In addition, carbon monoxide from the chimney, entering the combustion chamber through the chimney slots, can extinguish the burner or reduce the force of its combustion;
3. With the walls of the coaxial chimney broken by corrosion, the danger of blowing out the flame by gusts of wind significantly increases, which means that the gas in its pure form will seep into the living quarters. This means only one thing - the wind protection of the chimney is mandatory, as well as checking the material from which the pipe of the parapet equipment is made.

For quite a long time, gas heating boilers have been among the most widespread and demanded. The reason for this popularity is obvious - the most accessible and inexpensive type of fuel is needed for the boiler to operate. The advantage of gas boilers, first of all, is that they can be used not only to heat the house, but also to provide its inhabitants hot water... In addition, modern boilers have a reliable protection system - even leaving the house for a long time, you can be sure that in your absence the parapet gas boiler will work flawlessly. Recently, it has become possible to use parapet gas boilers when creating individual premises not only for private houses, but also for apartments.

Advantages of gas heating

One of the main advantages gas system heating, many call the availability and low cost of fuel. In fact, gas is the cheapest fuel compared to wood, coal or electricity.

However, heating systems with parapet boilers have a number of other advantages:

• high level of efficiency;
• no need for isolation additional room in the form of a fuel storage. In addition, when using gas heating system the house will not have the pollution that occurs when coal is burned in a heating boiler;
• ease of use;
• the fastest heating of the coolant;
• environmental friendliness;
• the ability to control the amount of fuel consumption.

Heating systems with parapet boilers have one significant drawback - the owners of both private houses and apartments need to obtain a sufficiently large number of permits for the installation of equipment of this type... All of them are issued by the design bureau and the gas service. Although, it should be borne in mind that, despite the rather difficult process of collecting all the necessary permits and paying the numerical fees, you will be able to enjoy the warmth and comfort in your own home in the future.

Types of heating gas boilers

Today there are many types of gas heating boilers. They differ in the following parameters:

• price;
• functionality;
• used coolant;
• burner type;
• smoke removal principle;
• place of installation;
• power;
• the presence of an automatic control unit;
• dependence on the power grid.

Of course, this is only part of the list of differences between gas heating boilers. In fact, there are many more of them. The main difference, on which, in turn, many parameters of the boiler depend, is the installation of a parapet gas boiler. There are wall and floor standing gas boilers. Wall-mounted ones are less powerful, relatively cheap and are mainly suitable for apartments. High power gas wall parapet boilers are suitable for complex heating systems mounted on the "cascade" principle and including several boilers. A parapet floor-standing gas boiler in most cases is an analogue of a mini-boiler room and is capable of heating areas of several thousand square meters.

Smoke evacuation principle

For a gas parapet boiler, it is extremely important that the oxygen supply and fume extraction system is correctly installed. According to this parameter, all boilers are divided into two categories - with natural and forced draft. Natural smoke extraction means that combustion waste spontaneously leaves the room through a special chimney that passes through the roof of the house.

Forced draft is carried out by exhausting the smoke through a system of coaxial pipes that go out through the wall of the house.

Forced draft is most often found in turbocharged (parapet) heating boilers, which are equipped with special powerful fans specifically for fume extraction. It is they who contribute to the movement of smoke through coaxial passages to the street.

The natural draft boiler uses air taken directly from the room. Such gas parapet boilers are called open. The use of a boiler of this type presupposes the presence of a high-quality ventilation system in the room, thanks to which fresh air will continuously flow into the room.

If a closed-type parapet heating boiler is used, which assumes forced smoke extraction, then the air enters through a coaxial pipe.

In fact, these are two pipes of different diameters. A pipe with a smaller section is inserted into a pipe with a larger one. Through a thinner pipe, smoke is emitted, and through the space formed between the walls of the pipes, air from the street freely enters the combustion chamber. A simple conclusion can be drawn - the use of parapet boilers equipped with such a smoke exhaust system is more environmentally friendly and convenient - after all, the oxygen necessary for combustion enters the parapet heating boiler from the street, and is not taken from the room. Parapet boilers have another advantage - coaxial pipes can be placed not only vertically (a mandatory requirement for systems with natural smoke exhaust), but also horizontally. This, to some extent, simplifies the choice of a place for installing the unit.

Boiler functionality

Regardless of the type of boiler (wall-mounted or floor-standing parapet gas boilers), this device can have one or two circuits. Single-circuit parapet gas boilers are used only to heat the premises. But double-circuit parapet gas heating boilers have another additional function - they can not only heat the room, but also provide all residents of the house or apartment in which it is used with hot water.

Parapet heating boilers are equipped with instantaneous water heater... Most often, this element is made of copper, since it is this metal that has the best thermal conductivity.

A clear advantage of parapet boilers is that they can be connected to the heating system from either side, or even from both sides at the same time. This greatly simplifies the installation of a parapet gas boiler - after all, you can find many places for convenient installation of equipment.

Parapet boilers are designed in such a way that they can run on natural gas. However, such models can be easily modified - replacing burners allows you to switch from regular gas to liquefied gas.

Heat carrier

In order to save money, many residents apartment buildings periodically use hot water taken from the heating system for domestic needs, as the reviews show. However, they do not know that special additives are used in such water, the main purpose of which is to protect the inner surface of the heating system from rust or solid deposits. The use of such water can have an extremely negative effect on health.

When choosing a heating boiler for an apartment, you should carefully read the technical characteristics of the device - after all, some of them are quite demanding on the quality of the water used in the system.

In this case, it is much easier for the owners of private houses - they can control the quality of the coolant themselves.

Advantages of parapet heating boilers

The advantage of the parapet boiler is, first of all, in its compact size. Even if you are the owner of a small apartment and have decided to create an individual heating system, the parapet boiler can easily be placed in the kitchen under the table, or even in a niche under the windowsill. If the distribution of the gas pipe allows, you can install parapet boilers in any convenient place in the house or apartment. Another advantage of the parapet boiler is the coaxial pipes, which greatly simplify the extraction of smoke.

Parapet gas boilers are wall-mounted, which greatly simplifies their installation. Floor standing boilers require a special room that is equipped in accordance with the requirements of the gas service. In addition, the installation of floor-type parapet gas boilers presupposes a wide chimney front door(not less than 80 cm). The room should have a window (for constant ventilation), in chimney there should also be small ventilation holes.

Do-it-yourself installation of a parapet boiler does not put forward such requirements. That is, there is no need to build a complex chimney pipe, to look for enough space to comply with all the rules for installing heating equipment.

Another advantage that parapet boilers have is that they can be connected anywhere in the system. Some models of boilers can only be connected to the right or left - but this requirement does not apply to parapet boilers. This greatly simplifies the installation of parapet boilers, allowing the boiler to be located in the most convenient place.

A distinctive feature of parapet boilers is their visual appeal. Most of the models are made in light colors, they are able to harmoniously complement any, even the most modern and elegant design. It should be noted that the paint used to cover the outside of the boiler does not fade, does not change its shade even with prolonged exposure to sunlight, the coating is not afraid of detergents.

Gas parapet heating boilers are equipped with a modern control unit. The automatic control system makes sure that the coolant in the system does not freeze - for this, a critical temperature level is determined, upon cooling to which the system automatically turns on and starts heating. In addition, the system is equipped with special sensors that monitor the pressure level in the pipes. Automatic control allows you to select the optimal level of heating the coolant - this allows you to reduce the consumption of fuel consumed.

Most parapet boilers are equipped with a piezoelectric ignition system. Thus, a single or double-circuit parapet gas boiler does not depend on the connection to the power supply system - this advantage is appreciated by the owners of country houses, who often observe power outages.

In a room where a single-circuit gas parapet boiler or a double-circuit boiler is installed, it is possible not to install radiators. This is due to the fact that the casing of the device has many convection holes - through them, heat enters the room, heating it.

Conclusion

A parapet boiler is an excellent solution to the heating issue, both in a private house and in an apartment. Imported parapet gas boilers are perfect for creating a hot water supply system - a double-circuit boiler is required for this.

If you have a low-power single-circuit boiler, you can use a boiler to create a DHW system. When choosing a heating parapet boiler, first of all, you should pay attention to the power of the device - after all, it is this indicator that affects what area can be heated with this boiler.

A parapet gas boiler is an apparatus with a hermetically sealed combustion chamber, which is used to heat the coolant and water in the DHW system. He fences clean air and the removal of combustion products outside the premises, excluding the release of carbon monoxide into the boiler room.

Features of the device

The body of such equipment has a rectangular shape, which adds convenience during installation, and the method of its fastening can be left, right or universal (two-sided).

The most popular are parapet boilers, the power of which does not exceed 15 kW, although on the plumbing market there are more powerful models designed for 35 kW or more.

Difference from analogues

At the time of development, boilers with a convector were conceived as a replacement for wall-mounted equipment for a similar purpose. After all, their predecessors require frequent maintenance, they are capricious and need high quality gas.

It is believed that the new kind heating equipment is less demanding to operate and does not need frequent maintenance. In addition, there is no connection to the chimney, which is a significant advantage and makes it possible to install it in any convenient room with an external wall.

Place of installation

In most cases, the parapet boiler is fixed in a niche under the window, where the radiator is usually placed. The main difference from wall and floor devices is the power range, installation method and outlet duct equipment. Currently, such a unit is a convector and a gas boiler at the same time, and can be installed not only in suburban areas, but also in apartment buildings.

The only thing worth remembering is the complete volatility of the device, because its operation will require a continuous supply of electricity. In this, it is completely similar to similar turbocharged devices designed to work in a heating system with forced circulation of an energy carrier.

Device device

Due to the design features and the type of purpose, such devices have firmly occupied the niche of the most popular elements of the heating system. Their device allows the unit to be used universally in various conditions.

Contours

Parapet boilers, like most of these units, can be single-circuit or double-circuit, so they perfectly cope with the task of heating water for household needs where there is no hot water supply, and they do it simultaneously with the main purpose.

Chimney

For the normal operation of the device, it is not necessary to have a vertical chimney, since the process of removing combustion products is carried out through a through hole in the wall.

Such a coaxial chimney consists of two pipes that are interconnected. One of them is responsible for supplying oxygen, and the other for removing carbon monoxide to the outside.

Convector

The convector integrated into the boiler body makes it possible to do without additional installation of radiators and other heating devices, if this does not violate the thermal balance.

In order to create a comfortable indoor climate, it is necessary to choose the right parapet boiler, having previously familiarized yourself with its technical characteristics.

Main advantages

After a little familiarization with the design features of the heater and the scope of its application, you can determine the main advantages that it possesses:

• closed combustion chamber and, as a result, the ability to install anywhere;
• the presence of convection holes, thanks to which you can do without additional installation of convectors;
• power sources - gas and electricity, which means that you can install the device in city apartments;
• a large selection of models with a power corridor from 15 to 40 kW, which makes it easier to select for rooms with different areas;
• the presence of single-circuit and double-circuit boilers;
• modern design that allows you to install the device in a conspicuous place;
• low cost, due to which the boiler becomes affordable for all segments of the population.

Right choice

Naturally, various models differ in technical parameters, which directly affect the advantages and disadvantages of the boiler.

Reliability

To judge the reliability of the device, it is necessary to find out how thick the steel of its body is. Unfortunately, some manufacturers neglect this rule and do not indicate this parameter on the heat exchanger packaging.

The optimal thickness of the steel wall is considered to be a parameter within three millimeters. If the thickness of the case exceeds this value, heat exchange processes will be slowed down, which will certainly affect the comfortable heating of the room.

Along with the thickness of the metal, the indicator of its quality is very important, which can be determined by the level of permissible pressure indicated by the manufacturer. Of course, the higher the indicator, the better and more durable the unit.

Profitability

The efficiency of parapet boilers is evidenced by their design and efficiency in operation. To find out how economical a heat exchanger will be, you need to find out its efficiency. It is this parameter that can best tell about the device's ability to save energy.

Today, the overwhelming majority of manufacturers strive to conquer the market, therefore they monitor the energy-saving qualities of their products. So, the optimal value of the efficiency can be considered 90 - 93%.

Remember, this is the only metric that will most accurately tell you about the effectiveness of the device. However, it is also necessary to take into account the features of the heated room, its size and the degree of thermal insulation.

Technical specifications

When choosing a heating boiler, you need to pay attention to its dimensions, power and location of connectors and fasteners. All these indicators affect the installation process and the location of the boiler.

Pay close attention to the execution of the connection to the water supply and gas mains (left, right). This does not apply to devices with a universal (two-way) connection.

The power indicator in terms of its importance is hardly inferior to the efficiency of the equipment. The heat balance in the room and fuel economy will depend on the optimally selected parameter. If the capacity is excessive, you will be faced with excessive consumption of gas and electricity.

The average calculation looks like 1 kW per 10 m² of the room, however, thermal insulation, wall material and other features of the building are not taken into account, so it is advisable to double the kW figure. Thus, the negative effect of drafts, thin walls, dilapidated window frames will be neutralized.

Mounting

Parapet boilers are installed according to the same principle as convectors. Primarily in outside wall create a hole with a small diameter for exhaust gases and oxygen intake.

It is best to equip the exit point near the window, which will allow access to monitor its operating condition and, if necessary, carry out maintenance. There are a number of rules according to which installation work... They are quite simple and can be done by hand in the following steps:

• a coaxial chimney crashes;
• the first air pipe is installed;
• the water supply pipe is connected;
• fasteners are tightened, the heater is installed;
• the second branch pipe is mounted;
• chimney sections are installed at an angle;
• sections are connected to the branch pipe;
• protection is mounted, pipes for water supply are supplied, an expansion tank is connected.

Installation of a parapet gas heating boiler

How does a parapet boiler differ from a chimney

• Lack of a classic chimney. In classic boilers, air is drawn directly from the room. After gas combustion, the combustion products go into the vertical chimney under the action of natural draft. In parapet equipment, air intake and combustion products are removed by means of a coaxial chimney.
• The special design of the combustion chamber - a steel heat exchanger, two burners, a DHW coil, are enclosed in a sealed chamber connected to a coaxial chimney. Air intake is carried out along the outer contour of the chimney, after which it enters the burner from below. The heated air passes through a vertical heat exchanger and is removed from the boiler drum through the core of the coaxial pipe.

The normal volume of gas consumption for a parapet boiler, 10 kW, will be about 1 m³ / hour. A double-circuit unit will consume approximately 15-20% more fuel required to heat the hot water supply.

Which parapet boiler is better to choose

• Performance - average power indicators, calculated according to the formula 1 kW = 10 m². This formula is suitable for well-insulated buildings in the middle regions of the Russian Federation with a ceiling height of no more than 2.7 m.
• Functionality - parapet single-circuit gas boiler, works only for heating. To connect DHW, you will need to install an indirect heating boiler, which will require additional financial costs. Double-circuit parapet gas boilers are convenient in this regard, since they have a built-in water heating function and a switch that allows you to transfer the unit to summer or winter mode work.
• Manufacturer - the rating of the most reliable boilers, led by German manufacturers, Austrian and Czech models follow immediately behind them. Domestic parapet gas boilers with a closed combustion chamber have an attractive cost and good thermal performance.

• Domestic gas parapet boilers of Russian production - Lemax, Hephaestus, Barsky Machine-Building Plant, Helios, Danko, Conord, HeatLine, Taganrog Gazoapparat,
• Ukrainian gas heating boilers of parapet type for apartments and private houses - Termomax, ATON, Atem, Mimax, Termotechnik, Mayak, Dani, Proskurov, ROSS, Ochag.

How to install a parapet heating boiler

Requirements for the room for the parapet boiler

• Parapet boilers up to 30 kW, can be installed indoors, with with total area up to 7.5-8 m². It is allowed to use the kitchen and utility rooms for needs.
• The minimum ceiling height is not less than 2.2 m.
• Ventilation of the room - there must be a working supply and exhaust ventilation in the boiler room. Doors are installed without thresholds. Opening windows are required.
• Lighting - for every 1 m³ of the boiler room, there must be at least 0.03 m² of the window opening.
• Features of operation - maintenance of gas equipment is carried out at least once a year. Together with the boiler operability, the operation of the supply and exhaust ventilation is checked. On the check made, an act is drawn up.
• Commissioning of the boiler is possible only after inspection by a representative of the supervisory authorities, compliance with all requirements regarding the correct connection of gas equipment.

Chimney for parapet boiler

1. Horizontal section, in total, should not exceed 3 m.
2. When passing the floor slabs, a special block is used - cutting.
3. A condensate trap and wind protection are installed on the chimney head.
4. The chimney is installed at a slight slope from the boiler in order to prevent condensation from draining into the device.

How to protect a parapet boiler from the wind

• There is no wind protection at the chimney head. The factory-made casing already has a special insert that protects against gusts of wind. The protection can be made of any galvanized steel by attaching it to the casing with press washers or rivets.
• Incorrect settings are set - in order not to blow out the parapet boiler, it will be necessary to lower the permissible gas pressure at which the module will remain operational.
• Insufficient traction intensity - the device of the flue is made in such a way that the slightest violations in the traction characteristics will lead to the shutdown of the boiler. To eliminate problems, check the correctness of the chimney connection and correct any mistakes.

In order to prevent possible shutdowns of the boiler as a result of gusts of wind, it is better to entrust the installation of the unit to a qualified specialist licensed to carry out these works.

Weaknesses and strengths of parapet boilers

• Cons - parapet models have low power and are not intended for heating premises large area... The boilers are suitable exclusively for heating small private houses and apartments. The equipment is sensitive to mistakes made during the installation of the coaxial chimney.
• Pros - compact size and the ability to choose a boiler, with the required side of the connection to the heating system. The models are distinguished by low cost, energy efficiency and efficiency, in the range of 98-100%. A closed combustion chamber and the absence of a negative impact on the microclimate of the heated room reduce the requirements for their installation.

Parapet boilers are economical, reliable and highly popular with domestic consumers.

How to choose a parapet type gas boiler?

• Boiler device
• Main advantages
• Choosing a gas boiler

Natural gas can be safely called the most popular and convenient type of fuel for use in autonomous heating systems in private houses, since, unlike coal, you do not need to worry about regular replenishment of stocks, you just need to connect to the local gas pipeline. That is why the majority of individual heating systems are designed for the use of gas. One of the best options is a parapet gas boiler, which can also be used to heat a city apartment.

Such a boiler can be used to heat a city apartment.

Initially, such boilers were developed as an alternative to wall-mounted ones, which, despite the fact that they had a lot of advantages, were very demanding on operating conditions. For stable operation, they needed stable pressure, high quality gas, soft water and uninterrupted power supply. For this reason, they often failed and needed regular servicing. Therefore, over time, they were replaced by parapet boilers, which have less stringent operational requirements and ensure a more stable operation of the entire heating system.

A parapet boiler is a non-volatile heating system designed for installation in private houses and apartments, combining the positive qualities of gas boilers and convectors.

Boiler device

Parapet boilers have a closed combustion chamber that does not communicate with the room in which the unit is installed and does not emit combustion products into its atmosphere, which has great importance for small rooms with poor ventilation systems. For the same reason, such boilers do not require the creation of a traditional chimney, only a lateral coaxial (coaxial) chimney is sufficient, which is mounted from two pipes located in each other, to supply fresh air to the combustion chamber and remove combustion products outside. Due to the presence of holes in the body of the parapet boiler, there is no need to install additional radiators in the room. With the correct calculation and selection of a boiler model, one of it will be enough for full heating.

Parapet boiler device

Parapet gas boilers are mounted according to the same principle as convectors - by means of nozzles, the unit is connected to gas and water supply systems, if the boiler is double-circuit, and is attached to the wall with brackets. The coaxial chimney has a small diameter and can be laid directly in the outer wall on which the unit itself is located. The branch pipe is best displayed next to the window to make it easier to monitor its condition during the operation of the heating system.

Main advantages

• The main advantage of the parapet boiler is the already mentioned closed combustion chamber. Thanks to this design device, there is no need to install a full-fledged chimney, so the boiler can be installed in any room in which at least one of the walls is external.
• The presence of convection holes in the boiler body provides full heating of the entire room without the need to install additional convectors, since the parapet boiler is both a "stove" and a "battery", combining everything positive sides these devices.
• Possibility of installation in a city apartment. All that is required for a parapet boiler is the presence of a gas pipeline and electricity in the house. In apartments, the installation of parapet boilers is usually carried out in the window-sill space in the kitchen, if there is none, the unit can be installed near the wall, but in this case it will be necessary to create an external hole in it for the coaxial chimney.

The heater can be simply installed against the wall

• Wide the lineup parapet boilers allows you to choose the best option for rooms of any area. The power can vary from 15 to 40 kW, depending on the model chosen.
• Versatility. Among the lineup there are options with both one and two circuits. A parapet boiler with two circuits not only heats the room, but can also be used to heat water if there is no hot water supply in the house.
• For an individual heating system, parapet boilers have a relatively low cost, which makes them affordable for most segments of the population. Modern design the case does not spoil the general view of the interior if the unit is installed in a conspicuous place.

Choosing a gas boiler

Parapet boilers between themselves, in addition to technical characteristics and power, can be economical and reliable.

Reliability primarily depends on the thickness of the steel used in the design of the heat exchanger. Unfortunately, not all manufacturers indicate this parameter, therefore, when choosing a boiler, it is necessary to clarify this moment with the seller in a separate order, since this can play a key role in the operation of a parapet boiler.

Steel with a thickness of about three millimeters is considered optimal. If the steel is thicker, then the heat transfer process will slow down, which will negatively affect the overall efficiency of heating the room. In addition to the thickness of the steel, its quality also matters. It is possible to determine the quality of the metal and the entire boiler as a whole by the maximum pressure level allowed by the manufacturer. The higher it is, the more reliable and high-quality the selected parapet boiler is made.

The quality of the metal during manufacture can be determined by the maximum pressure level

The efficiency of a parapet boiler is influenced by the design of the heat exchanger and its efficiency. In order to determine how economical the selected boiler will be in operation, you need to find out its efficiency (efficiency), this parameter will most accurately show the efficiency of the heat exchanger and the boiler device as a whole.

By now, almost all manufacturers have achieved an acceptable level of efficiency, which is 90-92%. But just in case, it is worth clarifying the level of efficiency when buying, since in some cases even two or three percent may matter. This indicator is the only one that objectively reflects the efficiency of the boiler, because different rooms differ from each other in the level of their own thermal insulation, so the reviews of people who have already bought a boiler will always be subjective.

To significant technical parameters include the size, dimensions of the boiler, the location of the connection connectors and the power. The size and dimensions are selected in each case individually and depend on the place and conditions of installation. The location of the connectors is also important for the boiler. The modern model range includes options with both right and left connection of the boiler to the gas and water supply. There are also universal models that can be connected from either side.

Boilers come in various sizes, it all depends on the power

The power of a parapet boiler is no less important characteristic than its efficiency. It is on the choice of a model with optimal power that the quality of heating the room, as well as the efficiency of using the boiler, will depend, because if it is too powerful, then gas and electricity will be wasted. The formula of 1 kW per 10 m2 is often used, but in fact this is not correct, since this indicator is so average that it almost never corresponds to reality. When calculating the power of 1 kW per 10 m2, the difference between the apartment and the house, the number of windows in the room, the material of the walls, the height of the ceiling and other parameters that make up the overall level of thermal insulation are not taken into account.

It is best to double this formula, that is, take 2 kW of power per 10 m2, and not one. In this case, a margin is obtained that takes into account windows, possible drafts, thin walls or high ceilings of the room. But, of course, it is best to consult with experts when buying and determine the optimal boiler output on an individual basis in order to achieve the most optimal ratio of price and quality of heating.

The parapet boiler is economical, easy to operate, has a low cost, can act as a water heater and does not require the creation of an additional heating network, since it is both a furnace and a convector at the same time. Ease of installation allows you to connect the parapet boiler yourself, without the help of specialists.

Summing up, we can say that a parapet boiler is a convenient modern heating device that can be installed in any type of room, in a private house, apartment, garage or any kind of outbuilding.

Parapet gas boilers: advantages and disadvantages

Compact parapet gas boiler - perfect solution for country house, cottage, townhouse or city apartment. Its design allows you to abandon the arrangement of the gas duct, and does not require a significant area for placement necessary equipment... And the closed type of combustion makes the use of such heating equipment absolutely safe, even when installed in a residential area or kitchen space.

Like other types of boilers, this option is focused both on working exclusively with the heating system and on additional hot water connection - in this case, you need to choose a two-circuit model. Moreover, the device itself generates heat during operation and can be used as a convector in the room where it is installed. A parapet gas boiler can be non-volatile - with mechanical start-up and piezo ignition, or volatile - with automatic control. The second option is focused mainly on cottages and private houses. The first one is versatile and can be used both in apartments and in individual residential buildings.

Features and characteristics

Unlike many other models of heating equipment, a parapet gas boiler does not burn oxygen when generating heat, which is especially important in winter period... And its connection does not require the laying of complex communication systems - it is enough to have a wall available, suitable for arranging a hole intended for the output of a coaxial pipe. Through it, exhaust gases are removed and air is taken.

The obvious advantage of this type of construction is and wide choose models with different types mounts (floor, wall) - in this case, it is possible to install parapet gas boilers even in small rooms. And the availability of opportunities for connection both to the main gas pipeline systems and to gas cylinders filled with a propane-butane mixture, allows them to be used even in those regions and districts where the central gas supply is absent or not well established.

The types of burners used in boiler equipment can also be different. Most models use single or double deck options. Parapet gas boilers are equipped with heat exchange elements made of copper, cast iron or steel; in double-circuit systems, an additional coil is almost always copper.

The power of boiler equipment is one of its main parameters. Most household models are capable of delivering an output of up to 16 kW. It should be borne in mind that 1 kW of heating system power is capable of providing heat for about 10 m2 of the area of ​​a house or apartment. And for dual-circuit models, power indicators should be calculated with an increase of 30%. Efficiency is also important - here you should not be content with small, the higher it is, the lower the fuel consumption will be.

Advantages of parapet gas heating systems

Due to the peculiarities of its design, the parapet boiler is a completely adequate alternative to the systems of electric or main heating in apartment buildings, and when installed on the territory of a private residential building, it can cope with heating an area of ​​up to 160 m2 (with the appropriate equipment capacity). In addition, it has a number of quite obvious advantages that make the use of gas equipment even more attractive:

1. Affordable: the cheapest models with a small power reserve cost a little over 10,000 rubles, the most powerful ones cost up to 100,000.
2. Installation is possible in any premises with outside walls- from storage rooms and hallways to living rooms, kitchens and living rooms.
3. Instantaneous heating of water (in double-circuit models) allows to provide a capacity of up to 180 l / h, and is adapted for output to 4 points of water intake. Thus, it is possible to abandon the installation of a storage device, which significantly increases the area occupied by heating equipment, and does not create difficulties with the seasonal use of hot water supply.
4. Economical - costs for gas heating always lower than wood or electric, with a similar efficiency.
5. Safe - built-in control systems, both in mechanical and automatic equipment, ensure that the gas supply is cut off in the event of an emergency. And the sealed body of the combustion chamber prevents combustion products from entering the living quarters - they are quickly discharged outside through the coaxial pipe.
6. Demonstrates a high heating rate of heat carriers, undemanding to the quality of water in pipes and supplied gas.
7. There are no additional requirements for seasonal operation.

Of course, these are not the only advantages of the parapet boiler. But it also has some features that require separate consideration. For example, for the legal installation of such equipment in a house or apartment, it is required to obtain an agreement from the gas service, and draw up a connection project (if it comes on the main gas supply) to the source of the energy carrier. In the case of connection to bottled gas, it is also better to install and connect a parapet boiler under the supervision of specialists.

How is the chimney arranged?

Parapet boilers are equipped with coaxial-type chimneys, but they can also be connected to existing pipes brought to the roof of the house. In this case, the intake of air for the operation of the system is carried out directly in the house, through the ventilation grilles. But, this connection option is more likely the exception than the rule. In most cases, chimneys are installed directly in the wall, near which the equipment is installed. And the pipe brought out through an opening in the supporting structure of the building has a double structure, in which the combustion products are discharged through an internal chimney of a smaller diameter, and air from the street is supplied along the external circuit, providing the necessary flow of oxygen into the system. Such parapet boilers are completely autonomous, and the chimney can be installed to them both vertically and horizontally.

Connection and operation

Parapet boilers need to comply with certain operational requirements. In particular, they cannot be mounted directly to the wall without providing it with additional thermal protection from steel sheets or plates. It is not necessary to place objects that present an increased fire hazard in the immediate vicinity (at a distance of less than 30 cm) from the boiler gas equipment. These include curtains and curtains, upholstered furniture, polymer decorative designs.

The minimum distance from the wall at which installation is possible is 30 cm, the maximum is 2.5 m. Thus, parapet boilers can be installed in almost any room - from boilers and storage rooms to living rooms. Wall models are attached directly to the wall surface, and usually have a low power - they are most often chosen for the organization of autonomous heating in apartments or tankhouses.

The lack of natural ventilation in the room is a direct contraindication to the installation of a parapet-type heating system. Air circulation in space, even when it comes to the operation of closed systems, is important in ensuring safety.

When choosing a place for the location of the chimney, it is better to give preference to the section of the wall located under the window opening. In this case, maintenance or dismantling will be much easier. Install the chimney pipe at an angle to ensure condensate drainage. And on the outer edge of the pipe, a wind shield should be installed, otherwise, with strong gusts, the flame in the burner may go out.
