Gas heating element. Rating of the best gas heaters. Types of heaters and their main characteristics

Gas heaters are devices designed for local heating of a small area (6–10 square meters). Such devices allow you to organize autonomous or country house. The source of heat in them is liquefied gas, which is filled into the internal tank of the heater. A variety of designs of gas devices allows you to choose the appropriate option for autonomous heating of your home. What characteristics should you pay attention to when purchasing a device? How to choose a gas heater for a summer house?

Characteristics of gas heaters: power

When choosing the type of gas heater, you need to decide on the required technical characteristics devices. , what is the heating temperature, what area is the device designed for, what kind of fuel does it consume during operation. Designated characteristics technical unit must correspond to the operating conditions of the heater. What parameters are decisive in choosing a heating system?

Gas convector heater

Power is the main characteristic of a heating device. It shows for which room the device is supposed to operate. The power characteristic is measured in kW. At the same time, it is generally accepted that 1 kW of power allows you to efficiently heat 10-15 m2 of space. For example, if the data sheet indicates a power of 4.2 kW, this means that it is intended to heat an area of ​​50-60 square meters.

Specified in technical document power is maximum. In addition to the greatest (for its characteristics) heat transfer, the heater can operate in reduced power modes. For example, 1.6 kW, 3.6 kW. When moving a gas heater to another room, its operation can be optimized for new square. Or interior space, including it in the minimum heat generation mode.

Heater selection: taking into account the heat source

The heat source is the name of the liquefied gas. The heat source can be propane or butane. The choice of liquefied fuel type depends on when the heater will be used: in cold winter period, or spring, autumn. Propane has proven to be the most efficient room heater in winter frosts or at low temperatures above zero. Butane is more often used to create comfort in the off-season, on cool nights on open verandas, in summer cafes.

Gas heater for a summer house - the most practical solution

Universal designs can operate on two types of fuel: propane and butane. In this case, the amount of heat generated depends on the gas flow. The higher the heating temperature, the more gas must be consumed. The faster the fuel supply in the cylinder will run out.

Operation of gas heaters

There are many options for using gas heaters: celebrating the New Year at the dacha, drinking tea at open veranda, working in the garage in winter, protecting plants in the greenhouse. What unites them general feature: heating occurs locally and for a limited time.

Row additional devices helps to increase the level of comfort when using the heater. For example, piezo ignition and gas control. Control of heating operation in automatic mode programmed to stop fuel supply to the oxidation chamber in a number of situations. For example, when the heater is tilted or falls.

To prevent spontaneous combustion, the device is equipped with an automatic valve system. Such control and automation make the operation of the gas device safer and independent of the constant presence of a person.

The ability to connect to a gas pipeline adds versatility to the heaters. The same device can be used in a remote suburban area and in the courtyard of a private house, connected to a gas pipe or to a cylinder.

An important feature of the device’s operation is the so-called heating type: direct or indirect. At direct heating Air intake occurs from the heated room. Accordingly, combustion products are released into it. Therefore, the presence of ventilation in the heated space is important.

For indirect heating, a combustion product removal system and an air supply system to the burner are installed.

Selection of types of heaters: infrared, catalytic and convector

When choosing a heater, you need to decide on the principle of its operation (the method of heating the surrounding space). The heating method determines three types of devices:

• convector;
• infrared;
• catalytic.

Infrared ceramic heaters

They are the most effective for local heating. Their work is based on thermal radiation in the infrared range originating from the surface of a special heating element. This element is made of ceramic, so the heaters received a second name: ceramic.

Ceramic panels make heating effective for two reasons. Firstly, the heating temperature of the element reaches 800 ºC and above. Due to the increased heating value, infrared devices received another name - “light” (in contrast to “dark” devices, which heat up to 600 ºC). Secondly, heat does not simply escape into the airspace and rise to the ceiling. It is distributed among objects located in the work area.

There are many options for gas cylinders:

• floor, wall and ceiling;
• outdoor and indoor;
• a small portable suitcase for placing on the floor of the room;
• lamppost (or sun on a leg);
• a portable cylindrical device containing a small gas cartridge.

The design of an infrared heater for the street or veranda is significantly more expensive device heating for the home. Outdoor heater resembles a lantern support. At its base is located gas cylinder, and at the top there is an emitter on a long stand-leg. The portable device is designed for local heating of trade or advertising tents. In relation to the dacha, it is used less often.

Infrared heating has its own characteristics:

1. The volume of space located in the operating area of ​​the device is heated. This allows the heater to be successfully used for street work when the use of convectors is ineffective.
2. It is not the air that is heated, but the physical object located in the work area. This factor is also important for street heating or when working in large warehouses, where there is no need to heat the entire hangar. In this case, only part of the utility area is heated.
3. The operation of gas infrared heating does not depend on the availability of electrical power. This characteristic is especially important for dachas, where there may be no electricity during the autumn-winter period.

Provides automatic shut-off of gas supply when tilted

Infrared heaters have found interesting applications in suburban areas and garden and dacha areas. They are used to heat seedlings planted in open ground, from spring frosts.

Catalytic heaters

Catalytic heaters operate without flame. Combustion without a flame represents oxidation of the fuel at the catalytic surface. This requires a catalyst. The high cost of this type of device is explained by the cost of the catalyst. It contains fiberglass and platinum inclusions.

Innovative models of catalytic heaters do not contain platinum or its group of metals in the catalytic panel.

Catalytic gas heater works without flame

With this combustion-oxidation process, the amount of heat released is greater than during combustion with the formation of a flame. Another advantage of catalytic oxidation is its environmental and operational safety. This middle option In terms of heating efficiency, it is of better quality, but inferior to an infrared heating device.

The maximum surface heating in catalytic heaters is 500°C. The heating temperature allows you to efficiently heat a room of up to 20 square meters. Small country house, a small greenhouse, an incubator for chicks. For large areas (more than 20 m2), it is recommended to use infrared models.

Options for catalyst models equipped with a fan can significantly increase the efficiency of the device, its thermal power on the way out.

The versatility of catalytic heaters is determined by the fact that various fuels can be used. For example, gas or gasoline, gas or electricity.

Gas convectors

Gas convectors are the most common types of heating devices for open verandas or country houses. They are equipped with a heat dissipator - a fan.

These are the simplest and most inexpensive. The safety of their work is monitored automatic system gas supply and its regulation. Built-in sensors do not allow the case to heat up higher than 60ºC.

Operating principle of a gas convector

A variety of gas heaters allows you to choose the most suitable model For dacha use. Like any gas devices, heaters must be cleaned regularly and checked for possible leaks. Gas heaters can warm the space of a room, create comfort on an open veranda or heat a greenhouse, and protect young seedlings from frost.

Having a dacha or outside the city is the longed-for dream of many residents of modern megacities. Fresh air, tranquility, moderate physical work on the site, the absence of the crazy bustle of the city - what else is needed for good rest! Therefore, happy owners of dachas try to spend as much time there as possible, often moving completely outside the city for the entire summer season. And at other times, nature is very good, and trips to the dacha on weekends or holidays are practiced throughout the year, and often country estates even become the main “residence” of the owners.

But fresh air and a calm, peaceful environment are not the only components of the present home comfort. The premises must maintain a comfortable temperature level for residents, and this often becomes a problem. This is especially true when visiting a dacha in spring, autumn or winter, but the summer of 2017 shows that no one is immune from the cold even in such a seemingly favorable period. Not everyone has a real brick oven at their dacha, and you have to tinker with it for a long time to warm up the premises during a short-term visit. Electric heaters are quite “gluttonous” in terms of spending expensive energy. But there is a very good solution that modern heating devices provide - gas heaters for summer cottages.

Let's take a closer look at them - how they are classified, what operating principles are embedded in them, and how to approach choosing the optimal model.

Types of gas heaters and principles of their operation

Approximate classification of gas heaters, their general advantages and disadvantages

It would seem that the design of such heaters is common, and is based on the principle that a burning flame heats the air, which, in turn, provides normal temperature indoors. However, this is not at all true. The device of many modern devices based on the use of modern technologies for heat generation and transfer. So both the design and the principle of operation different types Gas heaters can vary dramatically.

All gas heaters can be classified into several groups:

• Heat gas guns (powerful fan heaters).
• Ceramic gas heaters.
• Gas convectors for stationary installation.
• Catalytic gas heaters.
• Compact portable gas heaters.
• Outdoor infrared heaters.

Despite the differences in design and operating principles, all devices of this type have approximately the same advantages and disadvantages.

The advantages include the following:

• Natural gas, network or liquefied, is the most affordable of all other types of energy carriers in terms of cost. That is, such heating will not require significant operating costs. Some models require a connection to the power supply network, for example, to ensure the operation of fans and the functioning of control units, but their electricity consumption is minimal and will in no way be an additional burden on the family budget.

• The design of most gas heaters is quite simple and does not have complex components, which increases the reliability of such devices.
• Modern heaters have a very decent efficiency factor, that is, this indicates the cost-effectiveness and efficiency of their operation.

With some exceptions, gas heaters are characterized by high mobility - they are small in size, easily moved from place to place, and transported in a car. Many models can even be taken with you on a hike, fishing, or just when going out into nature.

• The operation of gas heating devices causes minimal damage to the environment - products complete combustion gases are practically harmless.
• The devices are usually easy to use.
• Warming up of the premises is carried out very quickly - such devices are not characterized by inertia in operation. For the same reason - gas heaters react very sensitively and quickly to changing settings.
• Modern products of this class are equipped with multi-level protection systems, which minimizes the likelihood of dangerous situations occurring.
• Most devices are distinguished by enviable durability - they can serve faithfully for 10 years or more.

However, despite the numerous “advantages”, there are also negative aspects:

• In any gas appliances, it is impossible to completely eliminate the problem of fire hazard, since highly flammable fuel is used, and the operation is accompanied by high-temperature heating. Such heaters require special precautions. It is unacceptable to leave them unattended if there are young children in the house.
• Unburned by itself natural gas– is very toxic, and any leakage can cause very serious poisoning, even the most tragic consequences. That is, this imposes additional requirements for operational safety.
• The gas combustion process requires constant influx oxygen, which in many models is taken directly from the room where the device is installed. This means that it is necessary to carefully consider the supply and exhaust ventilation system so that an atmosphere that is uncomfortable, heavy, or even dangerous to human health is not created in the rooms. By the way, the requirements for organizing ventilation directly refer to additional volumes of air circulation if work is planned in the room gas appliances. And if with water or electric heating These issues are sometimes looked at through fingers, but in the case of using gas heaters, a dismissive approach to ventilation is completely unacceptable.

What ventilation standards must be observed in a residential building?

This is not an idle question, and ventilation requirements are not taken out of thin air - they are clearly regulated by current regulatory documents. You can read more about this in a special article on our portal dedicated to problems.

However, when correct operation Such devices become reliable and faithful assistants, capable of quickly and effectively creating and maintaining the necessary comfort in country living conditions.

Well, now let’s look at the main types of gas heaters in more detail.

Gas heat guns

These devices actually vaguely resemble an artillery gun - a large metal cylinder, placed on a “carriage” - a stand.

One of the simplest types of gas heaters. The principle of operation is simple - a gas burner is placed inside the cylinder, and behind it a conventional electric fan is installed, creating a directed flow of air heated by the flame. The electrical part of the gas gun can be powered by mains or battery. As a rule, such devices are designed to be connected to a liquefied gas (propane) cylinder.

The advantage of such heaters is their low cost and simplicity of design. They are mobile - they are easy to move to the right place, and for this purpose special handles are usually provided on the cylindrical casing.

Such devices are usually equipped with a piezo ignition system. Certain stages of protection and ensuring operational safety are also provided. Thus, special sensors monitor the presence of flames, the temperature of the housing, and the oxygen content in the room. In the event of an emergency, the device will be automatically turned off and the gas supply to the burner will be cut off.

However, such heaters have many disadvantages. First of all, they are quite bulky for a living space. Direct combustion of gas requires a large volume of constantly supplied air, and combustion products do not produce much pleasant smell. In addition, an open flame is a big safety drawback.

Another significant drawback in the operation of such heaters is the rather high noise level. It can reach up to 70 decibels, which is clearly too much for a comfortable environment in the house.

In a word, they try not to use such heaters in residential premises. But to heat, say, a workshop during work, a garage, construction site or some kind of agricultural building - this is a very good option. Due to the directed hot flow, heating of even a large room will be ensured very quickly.

Ceramic gas heaters

But such devices can already be “put into the house.” The level of safety of their operation is much higher, due to a different principle of heat transfer.

Such a device also has a gas burner, and it creates numerous, but completely small tongues flames that heat not the surrounding air, but a special ceramic emitter. It, in turn, heats up to very high temperatures (from 600 to 800 degrees) and becomes a powerful source of infrared rays. Well, the advantages of infrared heating are known - thermal energy can be transmitted over considerable distances without dissipating in the air, but, being absorbed by optically opaque objects (including the human body), causing them to heat up. Well, heated objects, in turn, including, for example, walls, floors, ceilings, furniture, etc., will “share” heat through direct heat transfer with the air in the room. There are no fans, that is, the operation of the device is almost completely silent.

Such devices can be connected to mains gas or run from a gas cylinder. By the way, the design of the body of many models provides for the hidden placement of a standard cylinder in it.

The range of heaters of this type offered for sale is very wide. Moreover, models can differ in size and power, in external design, and in the way they are installed indoors.

So, you can buy a very miniature heater, almost table-top, with a small gas cylinder inside. Such a device is suitable for creating a local heating zone, for example, in a place where the owners traditionally relax.

For complete heating of the room, more “monumental” floor-mounted devices are used, like those shown in the illustration above.

It is also practiced to install heaters of a similar operating principle on walls and ceilings - they have a specific body shape that provides a directed flow of infrared heat in a given sector.

Such devices are very effective both for completely heating the room and for creating “increased comfort” zones. True, ventilation will still have to be provided for them - gas combustion, one way or another, requires an influx of oxygen.

The safety system, in addition to the protection levels listed above, also provides for turning off the device in the event of its overturning. That is, the risk of overheating, for example, the floor surface due to careless handling or the fault of naughty children, is minimal.

Gas heaters of catalytic operating principle

This type of gas heaters can easily be called the safest to operate. The fact is that there is no open flame at all - the oxidation of gaseous hydrocarbons occurs on a chemical basis, due to a special fiberglass heating element, in which the finest platinum coating is used as a catalyst to ensure the desired reaction. Be that as it may, it is still a process of “combustion”, that is, oxidation, with the corresponding production of thermal energy.

With this combustion of gas, a minimum amount of oxygen is consumed, which has a positive effect on the atmosphere in the room. Model range– is wide enough, and you can purchase both a heater for full heating of a quite decent-sized room, and a compact mobile version.

In principle, devices with a catalytic operating principle could be considered the best option. The only drawback is their rather high price - but this is due to the peculiarities of their production technology.

Stationary gas convectors

If permanent residence is expected at the dacha, or trips out of town even in winter time are of a regular nature, then the best option would be to install a stationary convector-type gas heater.

Once installed, such heaters become indistinguishable from conventional heating convectors. The same characteristic rectangular body, “spread” along the wall, with slot-like openings at the bottom for the entry of cold air, and at the top for the exit of heated air.

But inside, of course, the device is different. There is a combustion chamber located there (most often - closed type) and a heat exchanger, cast iron or steel, through which the heated air flows pass. Cast iron heat exchangers are considered more durable, but they are heavy and somewhat inert. Steel ones are lighter and react faster to changes in settings or to the activation of the thermostat.

Most modern models have a closed combustion chamber, that is, the air flow is from the street, and gas combustion products are directly emitted there, which is extremely convenient. In addition, such devices pose virtually no fire hazard, since the flame does not come into contact with the air in the room at all. Air is supplied and gases are discharged through a coaxial chimney, vented outside through a hole in the wall. This, in principle, predetermines the stationary placement of such devices.

Such devices are not particularly expensive; they work equally well (after appropriate reconfiguration) with both mains and liquefied gas. Convectors of a stationary installation, with the correct selection of power, can well serve as the main, that is, the only source of heat at any time of the year.

The disadvantages are small, and even then they are very conditional. This is the immobility of the device (as well as any heating radiator) and the dependence on the availability of the power supply necessary for the operation of the coaxial chimney fan.

Execution can be different - from laconic forms to decorative “screens”, in which, by the way, the appearance of fire can be created, for greater picturesqueness.

There are gas fireplaces with open camera combustion, but with them it is somewhat more complicated - you will need to organize a full-fledged chimney. So for dacha conditions this is probably not the most convenient option

Prices for infrared heaters

infrared heater

Outdoor infrared gas heaters

Agree, it’s nice to spend time outside in the evening with family or friends. But sometimes cool weather simply drives you into rooms where the atmosphere is not at all the same. But there is a solution to this problem too!

We are talking about outdoor gas heaters that are capable of creating and maintaining a comfortable atmosphere within a certain radius around themselves, even in very cold weather. Such devices are usually given a characteristic shape, stylized as street lamps or original illuminated columns.

Such heaters operate from liquefied gas, the cylinder with which, as a rule, is invisible, since it is hidden at the base of the device. The block with burners and infrared emitters (usually ceramic type) is placed upward and has a reflector on top - a reflector that directs the heat flow cone-shaped downwards.

However, the shape may be different - for example, the emitter is located vertically, and the spread of infrared the heat is coming radially on all sides. There are also directional devices that distribute flows of radiant heat in a certain sector.

The devices are good for everyone - they are capable of creating a truly pleasant atmosphere even in cool weather. Everything is explained simply: the state of comfort does not always depend only on the air temperature - the direct perception of infrared radiation energy also plays a very important role. Remember a frosty sunny day - the warmth from the rays of the Sun is very well felt by the skin. And in photographs from alpine resorts, people sunbathing in the snow are quite a common occurrence. Exactly the same principle is used here.

Such heaters are widely used in places of traditional recreation, for example, open terraces cafes and restaurants. Having such a device at home is a very expensive pleasure, and they are very rare in the everyday life of the average summer resident. But if there is a family celebration planned or a meeting of friends outdoors, then, judging by the advertisements, there is the possibility of renting for an evening or two. This practice is widespread, and for little money you can very well organize a comfortable picnic in the open air.

"Camping" gas heaters

Heaters of this type have already been partially mentioned above. They can be of different types, but they are united by their small dimensions and weight, that is, the devices have exceptional mobility.

Many models have a gas reservoir located inside, very compact, similar to an aerosol can. Other devices are connected via a hose to a standard small-capacity cylinder.

With such a heater it is quite possible to warm up the air in the tent in the evening, or install it near you while fishing if it’s cold. They are often used in home workshops if it is necessary to perform this or that work in winter. And some models have another interesting “option” - a well-thought-out system of stands and brackets allows you to turn the heater into a gas stove on which you can quickly boil water or cook food.

In a word, even if heating issues are not so pressing, having such a small-sized gas appliance in your household will probably never be superfluous.

What is assessed when choosing gas heaters for a summer residence

If there is a need to purchase a gas heater for your dacha, you can be guided by the following criteria when choosing the optimal model:

• First of all, you need to clearly formulate to yourself why you are purchasing the device. Agree that heating a living room, an outbuilding, a garage or a camp “dwelling” are completely different things. About the main purpose various types devices have already been mentioned, but a few more tips would be appropriate.

If permanent residence is planned at the dacha, then optimal choice will become a gas convector for a stationary installation - it will provide adequate savings and constant maintenance required microclimate. But in the case when trips outside the city are carried out infrequently, it is undesirable to install such a device. Firstly, it can simply be “stolen”. And secondly, due to his capabilities, he will not be able to the shortest possible time create a comfortable atmosphere - with convection heating, this requires a certain time. For such use, it is better to get a ceramic infrared heater. It is easy to carry it in the trunk of a car, and the heating from it in the sector of its action begins to be felt almost immediately - this is a characteristic feature of the radial propagation of thermal energy.

• The power of the device must correspond to the intended use. It is useless to expect miracles from a low-power compact portable heater - it will not be able, say, to provide the proper temperature in a spacious room. Yes, that's not what it was created for.

If the task of replacing the heating system with a heater is not worth it, and the device will be used only in the off-season, the “race” for power will simply be inappropriate. But even in the case when the gas appliance is assigned the function of the main heat source, purchasing a model based on the principle “the more powerful the better” is also not a very reasonable approach. The choice must be balanced - there is no point in paying extra money for excess power, which either remains unclaimed, or which will most likely result in excessive gas consumption and an overly hot atmosphere in the premises.

How to approach the choice of power of any heating device (not just gas) will be described in the appendix to this article.

• often equipped with thermostatic regulators, with which you can set the desired temperature level in the room. When a given threshold is reached, the gas supply to the main burner is stopped and will be resumed only after the temperature drops to a certain lower limit.

It is also very convenient if the device has the ability to stepwise or smoothly adjust the heating power - either the number of burners used or the pressure of the gas supplied to them changes. Such options significantly reduce the consumption of “blue fuel” and increase the durability of the heater, since it will mostly operate in a “gentle mode”.

• The degree of safety of operation of the heater must be assessed. This has already been mentioned - protection is triggered, that is, the device is turned off in case of overheating, lack of oxygen, rollover, gas leak and other possible emergency situations.
• Dimensions, weight, mobility, that is, the presence of a wheeled trolley or carrying handles, external design- all this is at the discretion of the future owners of the heater.
• It would be a complete gamble to acquire such equipment second-hand or from “not entirely clear” sources. retail outlets. Whatever one may say, gas heaters are high-risk devices, therefore, they must pass factory tests, which is confirmed in the product passport. In addition, the manufacturer's warranty will be valid only if there is a corresponding mark from a specialized store in the documentation of the device.
• Prices for gas household heaters have a very wide range - from 1–3 thousand rubles for compact low-power models, to 30 thousand or more for “sophisticated” devices. Here the financial viability of the buyer comes to the fore.

A brief overview of the top models of household gas heaters

Types of heaters will be considered in the order in which they appeared above in the article.

They often operate with the ratio: 1 kW of thermal energy per 10 m² of room area with an average ceiling height of 2.5 ÷ 2.7 m. You can follow this simplified path, but a serious mistake in one direction or another cannot be ruled out. The fact is that the indicators of the required power depend not only on the size of the room - there are many other criteria related to both the location of the house (for example, the climatic conditions of the region of residence) and the characteristics specific premises. Therefore, it would be advisable to carry out a more accurate calculation taking into account these factors. Moreover, such calculations will not take much time - we suggest using a special calculator for this.

Below, under the calculator, brief explanations on working with them will be given.

For centuries, people warmed themselves by the fire and lit their caves, and subsequently their houses and apartments, with fire. Just a hundred years ago, English streets were illuminated by gas lamps, and gas jets were lit for lighting in apartments.

Over time, electricity has replaced gas lighting and heating everywhere, but even today gas heaters have not lost their relevance. Outdoor cafes, clubs, parks and campsites are often heated and illuminated with infrared gas heaters. They attract with mobility, affordable environmentally friendly fuel and high efficiency. These devices are in demand where there is no electrical networks. The choice is up to the consumer.

We have compiled a list of the best gas heaters based on expert assessments and reviews from real customers. Our recommendations will help you make a choice that suits your needs and desires. There are many competitors in the global technology market, but we have selected the best manufacturers and recommend paying special attention to them:

Gas control / For the street / Area: up to 40 sq.m/ With gearbox

A gas heater for your home is the best alternative to electric devices and batteries that consume large amounts of energy. Heating devices, operating on gas, are completely independent of electricity. To operate, they do not require any additional equipment other than a liquefied gas cylinder. Let's look at why they are so good.

Like any other heating equipment, a gas heater serves a great option to create a favorable temperature regime in small spaces, be it a country house, garage or barn. Today there is a large selection of devices of this configuration. Their operation is possible both from a cylinder and from gas supplied through a central line.

The advantage of gas equipment is a high degree of safety during operation.

Depending on the cost, devices can be equipped control sensors, thanks to which, in the event of an emergency, the equipment will automatically turn off:

• when the fuel pressure drops;
• when the device overturns;
• in case of increased carbon dioxide concentration.

Gas heaters can be of two types:

1. Portable.
2. Stationary.

Portable devices are also called mobile due to their practicality. The device can be easily placed in any room and, if desired, moved from one room to another. Many models are equipped with wheels. Such heaters operate exclusively from a household propane cylinder. There are many criteria under which protection can operate, their number depends on the cost of the unit.

Stationary models can safely operate both on the basis of liquefied gas from a cylinder, and when connected to a gas pipeline. For the convenience of consumers individual models are equipped with various nozzles, which are designed for different methods of connecting the device. The only mandatory condition associated with the installation of equipment is the presence of a chimney or the installation of a new one to which the device is connected.

If we consider the design of gas heaters, we can distinguish models of two versions:

1. Having a camera closed type. These are more practical models, since combustion products in the form of carbon dioxide can in no case leak into open space and thereby poison you.
2. Having a camera open type. To minimize the likelihood of gas getting out, such devices are equipped with an air analyzer and various safety valves. In case of emergency situation, the device will turn off automatically.

Types and characteristics

In cases where additional heat sources are required, excellent option will purchase a heater. The best option for heating your own homes is a gas-powered device. However, before you buy, identify your requirements for the future device.

Today there is a large selection of heaters designed for different areas, terms of Use. So, on sale you can find three types of gas heating appliances:

Infrared

To increase the efficiency of the IR device, it must be installed at the same distance from the things surrounding it, thus ensuring their uniform heating.

Infrared gas heaters consist of:

• metal case;
• heat exchanger;
• divider;
• control unit;
• gearbox

The dimensions of the device can be different: small, weighing about 6 kg, which are suitable for heating rooms up to 60 sq.m., and impressive, which can be used to heat an area of ​​up to 100 sq.m.

Infrared gas devices are divided into:

1. Ceramic. They use a ceramic plate as a heat exchanger, which can heat up to temperatures above 800 degrees.
   
   
   
2. Catalytic(flameless combustion). Thermal radiation from such devices does not exceed 600 degrees.
   
   
   

There are also outdoor IR heaters. Their name speaks for itself. Such devices are good to use in gazebos, balconies, terraces, and lawns. The effectiveness of such a device is in no way inferior to the classic one. It, like a home gas heater, has a high efficiency. The only caveat is that the street space will be quickly consume heat emitted by heated objects.

Catalytic

The peculiarity of such devices is that they work without flame and noise, being the safest in the line of all gas-powered heaters.

Catalytic gas heaters heat the air space, not the objects around them.

The heat exchanger in such models is made of fiberglass, on which a catalyst made of palladium or the beloved platinum (with copper, chromium or iron oxide) is applied on top. When gas interacts with the catalyst coating, chemical reaction , the result of which is heat. It is clear that with this operating principle there is a complete absence of combustion products and smoke. Quite often, catalytic models are equipped with fans and electric heating elements, which increases their efficiency and makes them energy-dependent.

Convector

This type of device differs in the installation method. Installation of a convector device requires presence of a chimney. It, like the catalytic one, only warms up the space around it. However, it has a flame, like any other gas boiler. Oxygen, without which combustion will not occur, enters the device through the chimney. And through it the smoke is discharged to the street.

The operating principle of convector devices is as follows:

1. Gas is supplied to the chamber where combustion occurs.
2. Oxygen enters the firebox through the chimney.
3. Using a special button on the panel, the gas is ignited.
4. The flame heats the heat exchanger, which in turn transfers heat to the air.

This type of gas heaters work according to the convention principle. Through small oblong holes located on the body below and above, cold air enters the device, where it is heated using a heat exchanger. As a result, it leaves the inside of the heater, escaping to the surface through the upper slots. For more productive operation of the equipment, it is equipped with a fan that promotes active air convection. It turns on from the icon located on the case.

Convector gas heaters are equipped with a control unit and thermostat. With their help you can regulate the air temperature in the room.

Convector heaters, like infrared and catalytic models, are equipped control sensors, which are responsible for certain processes occurring inside the equipment. If any problems arise, the sensors will record this and activate the automation, which will turn off the equipment.

Advantages

That's all today more people prefer gas heaters. We list the advantages that the user receives during their use:

• independence from electricity;
• efficiency;
• mobility;
• practicality;
• aesthetics.

Undoubtedly, the main trump card of such equipment is completely independent of electricity. Indeed, all that may be required is the equipment itself and a gas cylinder. It turns out that such a device can heat any room in which there are no sources of electricity: a country house, a garage, a barn, any utility room and even a poultry house. In general, any square meters where you feel there is not enough heat or no heating at all.

A gas heater can be the best assistant in another situation. Surely, the owners of their own houses were faced with a situation where, due to heavy rains, strong squally winds, and snowstorms, a power line was broken. Of course, if such a situation arises, the house can cool down in a matter of hours in the cold season. This circumstance will seem especially unpleasant to families with small children. However, having a gas heater will protect your family from unfavorable circumstances.

Another important advantage is tangible savings. As you know, electric heaters consume a lot of electricity. Gas appliances, which operate on a different principle, can save your family capital. And this is a significant advantage.

The mobility and practicality of many models is achieved thanks to the small size of the equipment and the presence of wheels. The heater can be easily moved from one room to another, or even moved into a garage or shed.

Among the disadvantages are the difficulty of installing some models, the risk of explosion and slow heating of the room.

Conclusion

Gas-powered devices can fully compete with other heating devices. Due to its efficiency, independence from electricity and aesthetic appearance, gas heaters have long won the trust of their consumers.

However, many people are still somewhat suspicious of such devices, fearing for their safety. They believe that gas-powered devices remain the same today as they were 5-10 years ago. But modern technologies do not stand still, with their help gas heaters have long become safe for health person. All that remains is not to forget to ventilate the room in which they work.

Methods for heating residential and non-residential buildings are very diverse. There are many options and every owner country house, cottage, garage or workshop finds its own solution. The ideal one is the one that requires the least amount of resources and gives the optimal result. For many, this solution is a gas heater for the dacha. It does not require a complex piping system or installation of boilers, takes up little space, and does not need to be connected to the power supply. The only difficulty is to choose the right model that suits the owner’s purposes.

How do gas fuel heaters work?

For a heater of this type to function, it is not necessary to connect the building to any communications. It can work in rooms where there is no light or gas pipeline. Gas in a cylinder is used as fuel. Using infrared radiation, the device heats objects, which then release heat into the air. This allows you to use energy resources more economically and get maximum returns. Gas heaters for home almost instantly create zones of thermal comfort in unheated rooms.

Constructions different models may vary greatly, but the principle of the device is approximately the same. Inside the insulated chamber there is a gas burner, there are thermostats and valves that ensure the safety of the devices, and emergency shutdown systems. Reflectors are used to transfer heat into the room, ceramic panels, perforated sheets. The device casing can heat up to 60 degrees, which guarantees no burns when touched. Gas is supplied through a hose or stored in a special built-in container.

Pros and cons

Design features provide the following advantages of gas heaters:

• Reliability. How simpler design, the fewer elements that can break, and the more reliable the device itself.
• Small sizes. The devices are compact, making them easy to transport and move from place to place, and they occupy a small area.
• Cost-effective without sacrificing efficiency. Liquefied gas is used to heat the premises. It is used rationally, so you can get a greater effect with less fuel. The efficiency of the devices reaches 80%.

In general, gas appliances can hardly be called completely safe. As statistics show, there are indeed accidents associated with their use, but their number does not exceed the number of tragedies that occurred due to electric heaters. If compared with liquid fuel heaters, gas heaters are definitely safer. When operating gas appliances, it is important to adhere to safety regulations and ensure good ventilation in the premises.

Installation of gas heaters is not particularly difficult, but it is better to entrust it to qualified specialists

Types of gas heating appliances

There are the following types of heaters:

• ceramic infrared heaters;
• catalytic;
• gas convectors.

How catalytic models work

Catalytic infrared heaters are a good option for country houses and cottages. Devices of this type operate silently, are safe and environmentally friendly, and are very effective. The heater runs on liquefied propane-butane; a catalytic panel (usually made of fiberglass with platinum) is used as a heating element. Models with additional fan heaters are more efficient, their power can reach 4.9 kW. One catalytic heater is enough for high-quality and quick heating of a room up to 20 sq.m.

Advantages and disadvantages of ceramic infrared heaters

There are ceramic (they are called light, because the radiation temperature exceeds 800 degrees) and catalytic (dark, temperature below 600 degrees). Features of gas infrared heater – high efficiency, durability and reliability. Their disadvantage is their relatively high price, but their advantages include autonomy, uniform heat distribution, ease of installation and operation.

During operation, the heater does not burn oxygen, which allows you to create a comfortable microclimate in the house. Infrared models are varied and differ in aesthetic design. There are not only floor, but also wall, ceiling heaters. They can be used in residential buildings, country houses, workshops, and garages.

Infrared devices can be used in both residential and non-residential premises

Gas convectors for heating country houses

The devices are autonomous systems heating They are safe, reliable, different high efficiency. Combustion products and gas are discharged outside and do not enter the room. Gas convectors quickly warm up rooms and are used as the main or additional heating, are able to maintain temperatures from 13 to 38 degrees. The heating intensity is adjusted automatically. If desired, you can set different temperatures in different rooms of the house.
