Gas convector. Gas heating convectors: principle of operation and operation

this is a wall-mounted air heater that is great for warming up summer cottages, offices, warehouses and industrial premises.Main distinctive feature is that it has a combustion chamber with air intake from the street and the entire emission of combustion products also occurs on the street.

Residential, office, industrial or administrative premises today can be efficiently heated without spending large Money and not depend on the work of utilities and district heating. Purchase an easy-to-install, convenient and inexpensive gas convector in our company and appreciate all the advantages of such autonomous heating.
Purchased and installed at home or at work heater providing required amount heat due to gas combustion, you will not be afraid of severe frosts, which often lead to freezing of water in the system central heating and disable it. In addition, you decently save on space heating. After all, gas convectors are cheaper than electric counterparts. And wall models also save space.
The advantages of this equipment are so obvious that many users prefer to use it not only as a spare, but also as the main source of heat.
All gas convectors presented in our catalog (Turkish - Alpine Air and Italian - Bartolini CALORAMA production) are characterized by: compact size and stylish design, fast warm-up and high efficiency, protection against overheating and high wear resistance, long and safe operation. They will harmoniously fit into a room of any size and purpose and provide comfortable temperature in the room during the cold season.
All offered models take in air for heating from the street and thus do not burn oxygen indoors. In addition, they have horizontal pipe for gas removal and a closed combustion chamber. Each device provides the possibility of using both main natural and liquefied gas in cylinders. Convectors differ in the presence of a cast-iron or steel heat exchanger, different weights and power. It is according to the latter indicator that the choice is often made in favor of one or another gas convector. Usually, the calculation of power occurs depending on the area of ​​\u200b\u200bthe heated room (1 kW per 10 square meters). The differences between our models also include different type ignition: electronic or piezoelectric (battery operated).

Do you have a small country house outside the city. Two or three rooms, kitchen, terrace. Even if you do not use it in winter, on cool nights of the planting and harvesting periods, on a rainy summer evening, you really want warmth in the house. What is the best way to heat it up?

Building a stove is expensive, buying a potbelly stove is dangerous and not profitable, gas boilers and the heating system will cost a pretty penny ...

For such purposes, it is better to install heating using gas convectors. Convectors can work both on the main gas, and from cylinders with liquefied propane-butane. Consider, first, the option of heating from a cylinder with liquefied gas. Most suburban areas do not have mains gas. You can install one or more gas convectors in the house, depending on the number of rooms in which you want to create comfortable conditions residence. Convectors are mounted permanently on the wall of the heated room. They need to be selected according to their power. For example, the Turkish company "Alpine" (formerly DEMRAD) supplies gas convectors with a capacity of 2.65; 3.75; 4.4; 5.0 kW. The Netherlands supplies "BAXI" - 1.5; 2.3; kW. As well as other companies such as Bartolini, Mora (Gorenje), NGS, Karma, Italkero ... For normal year-round heating of a room up to 18 m2, you will need a 1.8-2.5 kW convector; a gas convector with a power of 5.0 kW is capable of heating rooms up to 45-48m2. If heating is not performed in winter period, less power per square meter will suffice. Do not forget about the thickness and material of the walls! In addition to gas convectors, you will also need: a cylinder or two cylinders for liquefied propane gas with a valve, a reducer, fittings for gas distribution, a metal cabinet for storing cylinders.

Domestic cylinders for liquefied gas are produced in volumes of 5, 12, 27, 50 liters. With a sufficiently long heating period or, in the case of installing several gas convectors, it is most advisable to use 50-liter cylinders. A welded steel cylinder for liquefied hydrocarbon gases GOST 15860-84 is always equipped with a valve. The remaining sizes of cylinders are produced in two versions: with a built-in valve device for a pressure regulator, the so-called "frog", and with a valve that involves a threaded connection with a reducer. From the point of view of safety and reliability in operation, it is better to purchase cylinders with a valve and a threaded reducer RDSG 1-1.2.

When heating in winter with the placement of the cylinder on the street, it is recommended to use high-quality imported gearboxes, which guarantee reliable performance in the required pressure range at outdoor temperature up to -25 C.

Cylinders can be installed inside the house in the kitchen, pantry, on the terrace. However, from the point of view of safety, air purity and the release of usable space, it makes sense to install cylinders with a capacity of 50 liters in special metal cabinets at outer wall Houses. Gas distribution from the cylinder to the convectors is recommended to be carried out steel pipes 1/2" or 3/4". The pipe from the cylinder to the convector must be completely curved without corners and other threaded connections. In places where the pipe branches, the connection is made by welding. AT last years distribution is also received by internal gas pipelines made of special reinforced plastic pipe or copper. But these innovations have not yet been reflected in the SNiPs and the Rules of the Gosgortekhnadzor. It is allowed to connect the pipe to the gas convector using a special flexible gas hose. In this case, a tap must be installed between the pipe and the hose. One of the possible schemes for installing gas convectors is shown in Fig.1.

How much will it cost to install and operate gas convectors on liquefied gas?*

Let's consider two options:

One convector with a capacity of 1.5 kW with a cylinder of 50 liters is installed in the house, installation under a canopy;
- two convectors are installed in the house - one with a capacity of 1.5 kW, the second - 3.75 kW with 2 cylinders of 50 liters installed in a closet outside the house.

In the first case, approximately the following costs await you:
Equipment and materials:
Gas convector BAXI Brazilia F5S -10,000 rubles;
Cylinder 50l with a valve - 1800 rubles;
Reducer Italy - 500 rubles;
Seamless steel pipe 1/2 inch (3 meters) - 600 rubles;
Flexible eyeliner (2 meters) - 1000 rubles;
Ball valve gas - 500 rubles;

TOTAL materials: 14400 rubles.

Installation and commissioning:

Installation and configuration of the convector - 5500 rubles;
Installation of gas wiring - 3600 rubles;
Transportation costs (up to 30 km from the Moscow Ring Road) - 2000 rubles.

Total installation: 11100

TOTAL: 25500 rubles

In the second case, the costs will be approximately 50,000 rubles.

Filling a 50-liter cylinder in the Moscow region costs about 550 rubles.

Gas consumption during the operation of a convector with a power of 1.5 kW in the maximum heating mode is 0.15 kg / h. Thus, a 50 liter bottle provides 150 hours continuous work at full power. Taking into account the inclusion of heating in the spring and autumn periods and heating in economy mode on cool summer nights, a 50-liter cylinder is enough for one 1.8 kW convector for one season (May-September).

What are the advantages of heating a cottage with gas convectors?

Convectors are quickly and easily installed in the house and do not require dismantling for the winter.

Convectors do not have a water circuit, so there is no problem of freezing of the coolant and damage heating system. Convectors do not require power supply (in some cases only for electric ignition).

Gas convectors have the ability to raise the temperature in the room to the required level in the shortest possible time after switching on.

Convectors are very economical due to high efficiency and modern automation system that provides automatic temperature control in the room. Convectors are safe thanks to high quality protective automation.

Another remarkable property of gas convectors is their environmental friendliness. Convectors have a closed combustion chamber not connected with the heated room. Combustion air comes from the street, combustion products are also removed there.

In conclusion, let us dwell on the question of the feasibility of installing gas convectors in houses with a natural gas pipeline. If a double-circuit gas boiler is already installed in your house, providing heating and production hot water, then the use of gas convectors will be effective for heating new extensions, such as: attic, covered terrace, garage, etc. During the initial engineering arrangement of a house, in some cases, a combination of electric water heater and heating systems based on gas convectors. If your task is only to heat the house, then gas convectors are the most economical and comfortable solution. With minimal, compared with classical systems gas heating with a water circuit, the initial cost of gas convectors will allow you to maintain an individually set temperature in each room and ensure economical gas consumption.

The issue of heating a house is best resolved by consulting a specialist " First Gasman". The installation of gas equipment and the wiring of the internal gas network should be carried out only by certified specialists who have the necessary qualifications and experience with this type of heating equipment.

For space heating, various heating devices and devices are used. Gas convectors are considered reliable and practical in operation. The heat that comes from this device is transferred as quickly as possible into the space of the room. It is possible to equip a house with these convectors both with a centralized and with an autonomous heating system.

The principle of operation of the gas converter

Heat enters the room due to the convection of the heating device, when warm air flows from the hot heater. The gas convector is equipped with a special sealed combustion chamber, it is the surface of this chamber that heats up during gas combustion.

The method of convection is based on the fact that warm air that comes from a heat source goes up. Cold air (which is heavier) falls down the room and, in contact with the convector, heats up and goes up. Yes, due to constant circulation air flow warms up the entire room.

In order to increase the power of the gas convector and maximize the heating of a room of any size with natural gas, some devices install a fan heater. It accelerates convection in forced mode, and this, accordingly, significantly reduces the time to heat the room to the desired temperature.

Features of choosing a gas converter

When choosing the required model, you need to take into account certain operating conditions, study reviews, find out the price, know the area of ​​the room and highest temperature for heating. Detailed description all technical properties and criteria will help to cope with the task of buying the optimally best gas convector.

Like all heating appliances, gas convectors have their own characteristics that you need to take into account and understand how to choose the right convector for your home:

• circulation method. The presence or absence of a fan heater.
• Thermal power.
• Installation option. Floor or wall.
• Extraction method.
• heat exchanger material. Steel or cast iron.

Floor standing or wall mounted gas converters

Taking into account the criterion of saving space and working conditions, more practical and suitable are considered wall mounted gas convectors. They do not take up very much space and are usually installed on the wall near the window, thus obtaining an additional thermal curtain between the room and the cold window.

But these devices should be fairly light and not create a large load on the wall. Gas convectors on the wall are limited in terms of thermal performance to 10 kilowatts.

If necessary, heat a large number of areas, then use a more powerful outdoor gas equipment . These devices create large quantity thermal energy, but also have much larger dimensions, as well as significant weight, they need a reliable and stable foundation.

The price of floor-standing and wall-mounted devices is approximately the same with similar equipment capacities.

Thermal power

When choosing a gas convector, you need to take into account heated room size. It is this parameter that is considered fundamental in calculating the efficiency of a gas convector. There are a number of methods for calculating the required power.

The main calculation takes place taking into account the following rule: for every 10 square meters of the room, 1 kilowatt of heat is consumed.

This is universal formula, it is most suitable for standard rooms with a ceiling height of no more than three meters, the usual arrangement of doors and windows and good insulation.

If more careful calculations are needed in poorly insulated or non-standard rooms, then you need to contact professionals.

Gas converter heat exchanger material

The operation of the convector is based on the combustion of gas in the thermal chamber of the equipment, and the heat exchanger inside is subjected to the most powerful thermal effect, the heat exchanger burning out quickly disables the device. That is, of course, the material of manufacture simply must be most stable and durable.

In this case, the clear leader is cast iron. The cast-iron heat exchanger is thermally stable, the service life of these gas convectors is more than 50 years.

Another advantage of a cast iron heat exchanger is the slowest cooling and even heat distribution. The disadvantage, judging by the reviews, is a lot of weight and a high price.

Steel convectors with a heat exchanger at a price cheaper and lighter than cast iron. But during the purchase, you need to pay attention to the quality of steel, this gas convector can last at least 30 years.

Closed or open combustion chamber

A simple hood is based on the intake of air from the house and the removal of combustion products into a vertical chimney.

The simplest gas convectors are arranged according to this principle, the disadvantages of this device are obvious. This is burning air in the room, the need for a converter in good ventilation and the creation of a complex chimney that passes through the roof and floors.

The advantages of these devices are slightly less price, unlike other devices with the same parameters.

Convectors with closed camera burning. Here, the draft is supported by a fan built into the chimney.

With this equipment option settles down coaxial chimney , through the internal pipeline of which products exit gas mining, and air is taken into the combustion chamber along the annular distance.

Forced operation of the chimney is carried out using the installed centrifugal fan. This can be done by a convector with a volatile and closed combustion chamber, it is much easier, safer and more practical to install.

Fan heater installation

The installed fan heater provides fast and uniform heating of the entire house. Another very important factor is the supply of air to the heat exchanger, this entails forced cooling of the hot body.

This creates some protective measures from constant heating, thereby extending the service life of the material from which the heat exchanger is made. This cooling is all the more valuable in devices with increased thermal power (thousands of kilowatts).

What gas should be used

Initially, gas convectors are designed for connection to the central gas pipeline. Thus, it seems that they operate only on natural gas.

But when using special kit adapter, gas convectors quickly switch to operating mode on liquefied gas. Certain brands of convector models are initially designed with the possibility of switching to liquefied or bottled gas.

Features of work on natural gas:

1. Clear technical requirements to the conditions of operation and installation of equipment. It is advisable to entrust the installation work to professionals, despite the possibility of installing it yourself. And you need to strictly follow the requirements and safety measures.
2. You won't be able to save a lot: the price of natural gas is similar to the price of electricity in terms of 1 kilowatt of electricity.

The installation of a gas convector is justified and is great way out from the situation in those regions in which there are no centralized gas pipelines, and the supply of electricity occurs with large interruptions or is completely absent.

Advantages of a gas convector

But the savings are achieved due to the fact that only 0.1 cubic meters of gas is needed to produce one kilowatt of thermal power. All these statements are justified only when connected gas device to the main gas pipeline and the use of natural gas.

Disadvantages of the gas convector design

Dimensions. This indicator for a gas convector loses significantly. These devices are not very compact, especially floor models. Taking into account the need to increase the thermal power strongly increase in size and weight equipment.

The choice of several low-power convectors in a room where there are many windows. If there are several windows in the room, then when one convector is operating, the air in the corners of the room may be cold. To do this, you will need to put a convector under each window, which is not always economically rational.

Low inertia. Ordinary metal gas convectors quickly cool down and heat up. This parameter is not always a negative advantage, it all depends on the type of heated housing.

lack of mobility and the need to arrange a hole for a chimney in the wall are also a disadvantage of this type heating devices.

Gas convectors used to heat individual rooms and rooms using natural gas are considered economical heating systems. But if you need to heat several rooms or large areas they lose more efficient and economical boilers heating with autonomous system.

On December 30, we installed such a long-awaited convector. For several months we have beauty here - we have no water, we do not need light. In the first month, I burned about 150 rubles. The first month, of course, is longer until they warmed up their house.

And before that, the apartment is 20 sq. m., paid 800-1000 rubles a month and there were often interruptions: there is no light - it's cold here, there is no water - it's cold again. And now, there are no problems. Magnificent thing. Would recommend to everyone to install.

The main thing is that it is quickly installed, the costs are small. Nothing complicated - one hole was made, no pipes, and the hood is near the window. All. Exhausts all go there. We open the window - and that's it. Satisfied, I recommend to everyone.

Max. Krivoy Rog

For a room of 80 sq. m. (room from fixed formwork, warm ceilings 2.80 m) in severe frosts, 60 liters of gas in a cylinder are enough for a week. Electricity is not needed at all! Really nice and warm. I advise everyone.

Vlad. Moscow

I bought it three months ago, read the gas convector reviews, Zhytomyr 5 KNS in a room of 25 sq. m. and in the bedroom an AGOK 2.5 convector with a cast iron heat exchanger. If you want to sleep in silence, do not regret it, add a couple of thousand rubles and choose with a cast-iron heat exchanger. Will run quietly and warm much better.

Andrei. Voronezh

The need for heating country house or giving often causes difficulties associated with excessive financial costs, as well as the need for a long and complex installation. However, there are also alternative solutions. Consider one of the most convenient and popular options today - a bottled gas gas convector: prices, model characteristics and operation features will be presented in the article.

Gas heating convectors have long been used by residents of Europe as one of the most economical devices for space heating. They run on natural gas, save owners the hassle of having old-fashioned stove equipment, and at the same time reduce heating costs. At first glance, it may seem that it is easier to install a gas boiler, but in reality, the purchase of a convector will significantly reduce the budget for arranging heating.

Natural gas gas convectors cannot be called a panacea, because they are able to maintain the desired temperature only in a small house, outbuilding or garage. In fact, if heating is not used in winter time, and, for example, in spring or autumn, this will be quite enough to maintain a comfortable temperature in the room, and the device high power will not need.

A gas convector for heating is the best way out if the house is not connected to centralized system power supply or the network often experience power drops. Thus, you can ensure permanent heating system housing. Moreover, this method is much more economical.

There are models of heaters that initially provide for the possibility of using liquefied gas as a fuel, however, for many models, you need to purchase a special adapter. Himself gas cylinder, under proper storage conditions, can be placed right in the house.

Helpful advice! Liquefied gas in a cylinder can be stored outdoors. To do this, you must first build a metal cabinet for it.

How does a gas convector for heating work

One of the main advantages that a gas convector running on bottled gas can boast of is its efficiency reaches almost 90%. At the same time, the scheme of its operation is very simple: gas combustion occurs in a special chamber, where Fresh air from environment. Due to this, a flame is maintained, which heats the heat exchanger.

In turn, the cold air from the room, getting inside the convector, collides with the heat exchanger and heats up. Warm air enters the room back through special shutters, equipped in the upper part of the device. The cycle repeats constantly and ends only when the indicator of the device reaches the set mark.

Here it is important to pay attention to the presence of a high-quality thermostat, since it is it that allows you to prevent overheating of the air in the room and economically consume gas reserves. The ability to set the desired air temperature is another advantage of using this particular device.

Helpful advice! To avoid the ingress of combustion products into the air, it is necessary to make a special outlet to the chimney.

How to calculate the power and gas consumption of a gas convector on bottled gas

The first criterion that will determine the choice of a convector is whether it is planned to be used as the main source of heat, or as an additional one. Let's consider both options.

If the gas convector is the main source of heat that heats the room, then 40 W / m³ will be used for calculations. This means that 40 W of electrical power must be used to heat 1 m³ of space. Further calculations are extremely simple: the volume of the room is multiplied by 40 and the required power of the device is found.

You can often find another formula for calculating: 100 W / m². At first glance, it may seem that it is much easier to calculate in this way, but it is wrong to do so. Ceiling heights in country houses can be very different, and if you do not take it into account in the calculations, then the purchased device in the end may simply not be able to cope with the task.

As an example, we calculate the required power of the device for a room with an area of ​​​​25 m² and a ceiling height of 3.2 m. Using the formula, we get: 25x3.2x40 \u003d 3200 W.

If the required power is too high and a suitable device cannot be found on sale, it makes sense to buy two or more devices and place them under the windows.

Placing convectors under the windows is one of the best options, because due to their ability to cut off the cold air coming from the window, they help to maintain the temperature set in the room even better.

The second option for using a convector is more common than the first. In this case, the device is used as an additional heat source and works in conjunction with other devices when their power is not enough. So, in severe frosts, it may be necessary to turn on the convector in order to create a comfortable temperature in the room.

If you plan to use the convector for this purpose, then it is worth making calculations from the following indicators– 25-35 W/m³. Here, all recommendations remain the same, and the calculation formula does not change. For example, for a room of 25 m² with a ceiling height of 3.2 m, the calculation will look like in the following way: 25x3.2x30 = 2400 watts.

If we talk about the consumption of gas per day by a gas convector, then here the indicators can be very diverse, depending on the set various factors. As a guide, use a value equal to 0.09 kg of bottled liquefied gas per 1 kW of the thermal power of the device.

Gas convector on bottled gas: prices for heating appliances

Before you buy a gas heating convector, you need to understand what makes up its price and why some models can cost more than others. First of all, it depends on the material from which the heat exchanger is made, as well as some design features. The quality of the instruments used to control the temperature can also affect the cost.

Helpful advice! Be sure to pay attention to the fact that all documentation related to the further maintenance of the device is filled out correctly. Otherwise, you will have to repair the gas convector yourself or hire a specialist at your own expense.

A heat exchanger made of cast iron is much more expensive than steel. Its warranty period is 50 years. So in this case, the waste will be justified. As for the design features, this means the presence of a vertical or horizontal chimney.

In this case, there is no fundamental difference, but it is worth starting from the fact that vertical systems, although they have great power, can not be installed everywhere. For example, for a bedroom, this is not a suitable option due to the large volume of gas burned.

Another factor that affects the price of the device is the presence of a fan. A gas convector with a fan provides more intensive air circulation in the room. At the same time, the price of a gas wall convector will not differ too much from a floor model with the same parameters.

The average price for this type of device ranges from 20-30 thousand rubles. However, you can find both cheap models for 10-12 thousand rubles, and more expensive devices. It all depends on power and availability. additional features. More details on the prices of specific convectors will be discussed below.

Overview of natural gas gas convector models: prices, reviews and specifications

The prices of gas convectors on natural gas, as well as their variety, are not limited by anything. Therefore, today it is not difficult to choose the right option. Consider the most popular models of gas heaters for summer cottages. Convectors of these manufacturers almost always receive only favorable reviews.

Gas convectors Alpine Air

Turkish-made wall-mounted gas convectors occupy one of the leading positions in modern market. They are convenient, compact, efficient and quite affordable. To get a complete picture of the product offered, consider several models in the form of a comparative table.

Any of these models can be chosen for home use. The most suitable option should be selected, focusing on the area of ​​\u200b\u200bthe room to be heated, as well as your own financial capabilities.

Helpful advice!Do not buy too powerful a device for a small room. Nothing but overheating of the air and excessive gas consumption, it will not.

Gas convector Hosseven

The Hosseven HDU 3 gas convector is perhaps the most popular representative of this Turkish company in our country. At average cost about 22,850 rubles, it has quite a decent power of 3000 W and is worthy of competition with similar models. Device parameters:

• dimensions: 635x470x270 mm;
• weight: 23.8 kg;
• combustion chamber: cast iron;
• There is no built-in fan in the device.

A feature of this design is that air is taken through a special horizontal telescopic tube, which is connected to the convector with reverse side. Thus, the device does not absorb oxygen indoors and does not need a traditional chimney.

Gas convector on bottled gas: reviews and benefits of use

If we summarize all the information reviewed, as well as take into account the reviews, gas convectors can be quite attributed to the best options problem solving, both with the main additional heating. Among its advantages are:

• complete autonomy, independence from power supply or any other communications;
• ease of installation compared to gas boilers;
• economy of use and low fuel costs;
• there is no need to equip a special boiler room for installing the device;
• you can not be afraid that the water in the system will freeze;
• the process of heating the air to the required temperature occurs very quickly.

Caring for this type of device can also be attributed to their benefits. The simplicity of the design makes it possible, if necessary, to repair the gas convector with your own hands, if guarantee period service has already expired. However, it will be safer to seek help from specialists in order to avoid possible problems with gas leakage, etc.

Do-it-yourself gas convector installation: video and installation tips

In order to carry out the installation of a wall-mounted gas convector without the involvement of specialists, you will need a number of tools and the ability to use them:

• drill with drills;
• perforator with a crown;
• screwdrivers;
• mounting foam;
• wrenches of appropriate diameters;
• plastic dowels and screws;
• convector;
• gas cylinder;
• gas supply kit.

First of all, decide on the place where you plan to install the device. There are requirements stipulated by GOST: if possible, the gas convector should be installed under the window. If this is not possible due to the design features, it is necessary to place it as close to the window as possible.

Helpful advice! It is important not only to choose a place, but also to make sure that the convector model you have purchased will fit there and will not interfere with furniture or free movement around the room.

After that, you can proceed to measuring and marking the necessary holes. To do this, use a tape measure and a pencil. by the most important point at this stage it is important to clearly define where the gas inlet will be located if you plan to install the cylinder in another room or on the street.

Drill the necessary holes and hammer the dowels into them. Fasten the convector to the wall using self-tapping screws. With help polyurethane foam close cracks and openings that can serve as sources of cold air entering inside. After that, you can proceed directly to connecting the gas cylinder to the convector.

The installation of the gas convector ends with its test run, which is carried out only after you make sure that all joints are tight and there is no gas leakage anywhere. After the first start, be sure to adjust the device.

Helpful advice! During the first few hours of operation, the chamber will burn, and you may smell burning oil. This is not dangerous and is easily eliminated by airing the room.

So, if you decide to buy a gas convector on bottled gas, then you have a difficult choice. Be sure to check everything before buying necessary calculations and decide which type of device suits you best. After that you can do right choice and provide your home, garage or outbuilding with warmth in the cold season.

The constant rise in the cost of energy and the low efficiency of central heating systems force the layman to turn to autonomous systems. In addition to traditional heating systems, where gas boilers are the heat source, the heating convector is very popular among the population. This is a self-contained heating device that runs on natural or liquefied gas and provides efficient heating a separate room. It works quite efficiently, is easy to install and has a simple principle of operation.

The principle of operation of gas heating convectors

As often happens, everything ingenious is simple and affordable, as is the case with heating convectors, whose operation is based on the principle of convection. This is a special type of heat transfer when thermal energy carried by hot coolant flows. Gas heating convectors can use both natural and forced circulation, can be equipped with automation systems and thermostats, but their device as a whole is simple and easy to understand. By and large, a convector is an ordinary gas burner and a heat exchanger hidden in the body of the device.

Many are interested in what are heating convectors? These are devices that have been known for a long time. As it turned out, such devices were used to heat their homes back in the 19th century. Since then, when acetylene and open burners were used to ensure the operation of devices, a lot of time has passed, convectors are constantly being improved and are still in demand.

The principle of operation of convectors is that the waste obtained during the combustion of gas heats the air that enters the device naturally or under the action of blowing devices. It rises up and enters the room, while the cooled air, according to the laws of physics, goes down and is heated again. Flow warm air in this case, it is constantly formed. Having dealt with the device and the principle of operation, you should move on to the features of the device and the main modifications of the devices.

Basic parameters and types of devices

As in cases of using other heating devices, there are main indicators based on which conclusions are drawn about the appropriateness of using a particular device. First of all, this is done based on the characteristics of the room, where special attention should be paid to its area, by calculating which you can choose a device of the required power. Devices low power will not cope with the tasks assigned to it, and their incorrect installation often leads to the fact that the interior of the room suffers. In this regard, it is worth considering two main types of devices:

Nowadays, much attention is paid not only to the quality of heating, but also to the design of heating devices, which should organically fit into the interior of the heated room. Based on these considerations, it is worth paying special attention to built-in heating convectors, which can be hidden in the floor and wall. They also work efficiently and perfectly cope with the assigned tasks, but at the same time they do not attract attention to themselves, which is especially important when arranging presentable offices of large companies. Particularly popular are floor-standing recessed heating convectors, hidden from visitors in the floor structure.

Convector hidden in the office floor

Convectors can also differ in the type of heat exchanger, which can be steel or cast iron. Steel heating convectors are used most often today, although no one has canceled the strength and high performance heat transfer, which traditionally demonstrate cast-iron devices. Cast iron devices are heavy, although they work flawlessly. In addition to the options considered, in recent years, special attention has been paid to the use of high thermal conductivity of copper. Copper heating convectors are the most efficient, they work for a long time, but they have one significant disadvantage– like other copper appliances, devices of this type very expensive and not affordable for all users.

All devices described above refer to devices closed type that are effective and safe.

circuit diagram forced draft devices

There are also open-type convectors for heating, in which the air used for heating is taken directly from the room, and the waste resulting from the combustion of gas is discharged into common system ventilation. Such devices are the most unpretentious, and it is quite simple to connect them, but they can hardly be called environmentally friendly.

Gas convectors, in addition, can be non-volatile, and there are devices whose operation directly depends on the availability of electricity. Gas-burner in devices of the first type, it burns constantly, only the burning intensity of the wick changes, and in the case of using volatile devices, in the standby mode, the burning stops, and the gas ignites again from a piezoelectric discharge occurring between the electrodes.

Positive points and characteristic disadvantages

The main condition for connecting convectors for heating a house is the presence of gas, if the conversation does not concern the use electrical devices. The ideal option in this respect are the premises connected to central systems gas supply, however, in our case, it is possible to heat houses located in an area not connected to a gas pipeline. Bottled gas is perfect for this, which is especially appreciated by summer residents who heat their homes occasionally. Converters have a number of advantages, but they also have some disadvantages. Their main advantages include:

• the possibility of using indoors for any purpose and various areas where the installation of gas equipment is allowed;

How does it look in the interior of the room

• like conventional radiators, convectors fit perfectly into the design of an apartment, house, industrial and office space;
• you heat one specific room, completely ignoring the adjacent rooms, which use your own devices for heating;
• they have a high efficiency, surpassing even most autonomous heating boilers;
• convectors for heating an apartment or house are easy to install, because for this you do not have to worry about the wiring of the heating system, which allows you to save on pipes and fittings.

Despite the obvious advantages, there are also some disadvantages of converters, which most often have low power and can heat only one room, which is easy to fix by installing devices in each room. In addition, unlike gas boilers, they work exclusively for heating and cannot heat water. Also, unlike traditional heating devices - radiators, convectors are more bulky, and it is difficult to hide them, if we are not talking about built-in appliances.

Calculation rules and installation features

Answering the question - what are heating convectors, we come to the conclusion that this is a heating device, the installation of which requires experience, at least. Work on their installation has a number of difficulties, which is associated to a greater extent with the dangers that threaten if any gas equipment is connected incorrectly. As with the connection of gas boilers, in this case, you must have the appropriate permit, and the connection must be made by a gas service specialist. In this case, one thing may depend on you - the correct calculation of heating convectors, which will allow you to choose a device whose parameters will allow you to effectively heat the room. The power of a heating convector is the main parameter on which the expediency of its use in a particular room depends. In order to choose the convector correctly, it is necessary to measure the area of ​​​​the room, and then compare the figures obtained with the nameplate power of the device. If the ceiling in the room is standard and does not exceed 2.8 meters, then a device with a power of 1 kW is enough to heat a room of 10 sq.m.

You can also do some preparatory work and hang a convector, but it is better to entrust this difficult moment to professionals. In the event that you decide to do it yourself, you should remember that the outlet pipe and the wall at the installation site of the device must have a double layer of insulation, which can be used as mineral wool based on basalt.

Currently, many companies are engaged in the production of gas convectors, but among them there are those that work in violation of basic norms and requirements. In order for the device to work for a long time, and the room was always warm, it is worth paying great attention to the choice of the manufacturer, which, first of all, must be known and inspire confidence. For example, it is better to buy a Minib heating convector manufactured by a well-known Czech company than to succumb to a more attractive offer, in terms of price, which is usually made by little-known manufacturers. Equipment from world brands in without fail tested on modern equipment, high-quality materials are used in its manufacture and modern technologies to reduce the consumption of gas and electricity. And do not forget about the danger that low-quality gas equipment entails.
