Operating principle of a gas convector

Knowing your options when it comes to heating your home is crucial to keeping it comfortable and warm. A popular option for effectively heating spaces is a gas convector. These small heating appliances are a popular option for many homes because of their straightforward but efficient operating principle.

Natural gas or propane are the fuel sources that a gas convector uses to produce heat. Typically, the unit has a fan, controls, heat exchanger, and burner. The burner ignites the gas and heats the heat exchanger when you turn on the convector. Heat is transferred from the heat exchanger to the surrounding air as it warms up.

The ability of a gas convector to quickly and evenly distribute heat throughout a room is one of its primary characteristics. To ensure that the room is adequately heated in every corner, the convector’s fan aids in the movement of the heated air. Gas convectors are the best option for efficiently heating small to medium-sized rooms because of their effective heat distribution.

The convenience and adaptability of gas convectors are also well-known. Convectors are much easier to install in a room than traditional radiators or central heating systems. They can be placed on walls or even stand alone on the floor. Because of this adaptability, homeowners can tailor their heating system to suit their unique requirements and tastes.

Additionally, gas convectors provide accurate temperature control, enabling users to modify the heat output to a level that suits them. With the thermostats and programmable settings included in the majority of models, users can keep their homes comfortably warm all day long.

In conclusion, gas convectors offer homes an effective, adaptable, and practical heating option. Homeowners can choose wisely when it comes to efficiently and comfortably heating their homes by being aware of how these devices work and their advantages.

What is a gas convector – design features and operation

The natural movement of air masses brought on by heating is known as convection. Many heating equipment models rely on the convection principle. Among the changes, the gas convector—what it is and the benefits it offers the heater device—stands out in particular.

How a gas-fired convector works

The natural convection of air is the basis for the heating of living spaces by gas heating convectors. There are always cold air masses at the floor of the space. The air rises during heating and then begins to cool. The natural circulation of air masses serves as the foundation for the operation of every convector.

Principle of operation for convectors

Here’s how a gas heating appliance operates:

1. Inside the convector there is a heat exchanger connected to convection channels.

The gas convector’s principle of operation has various benefits that set it apart from similar devices in a positive way.

Benefits of Energy Convectors

Convection heaters operate on an advantageous principle that offers various benefits.

• Less gas consumption – the air in the room is heated directly, not due to the heat carrier, which increases the efficiency of the equipment and reduces heating costs.

Only convector models with a fan require connection to the power supply network. The fan quickens the flow of air and raises the room’s temperature several times faster.

Types of gas convectors

You should educate yourself on the key distinctions between current equipment and the benefits and drawbacks of any modifications before selecting a convector.

• Method of installation – there are wall-mounted and floor models. The first ones occupy less space, are characterized by low weight and efficiency, are limited in performance (maximum power of 10 kW).

A floor model is preferable for heating a garage or other large space. Because of the larger heat exchanger, heaters are heavy. Floor convectors (industrial versions) can achieve several milliwatts of performance.

A closed combustion chamber is used in convectors of the new generation. A coaxial pipe serves as the chimney’s substitute. Since the air intake is done from the street, the room’s oxygen is not burned during operation. The sole drawback of closed combustion chamber systems is their higher cost compared to traditional models, ranging from 30 to 50 percent.

Whether the convector can be installed in the living room

Using gas convectors to heat a home or apartment is totally safe. In this instance, it is imperative to consider multiple factors:

• Models with a vertical chimney, equipped with an open combustion chamber. The operation of convectors of this type is allowed in private and country houses, but is prohibited in multi-storey buildings. In apartments it is recommended to install systems without a chimney.

How to choose a gas convector

The heaters’ technical specifications require consideration. Selecting a convector with a programmable control unit and a closed type cast iron heat exchanger is the best option.

• Power calculation. Air convection is used to heat the room. Consequently, heaters are effective only in a limited space. For each room it will be necessary to install a separate convector. The power is calculated according to the formula 100 W per 1 m².

Convector which company is better to choose

The following manufacturers offer heaters for residential use:

The available equipment has power ranging from 1.5 to 10 kW, allowing it to heat a large room up to 100 m² as well as a small workshop.

How to correctly put a convector

The operating instructions contain a detailed description of the installation standards, prerequisites, and restrictions. Specifically, it states:

• Installation of a gas convector in a wooden house. During operation, the body heats up to 50-55 ° C. It is necessary to insulate wooden surfaces in contact with heating parts of the construction. The rules of installation in a wooden house prescribe the manufacture of fire breaks in the roof.

Insulation is not necessary at the point of passage through the wooden wall when a coaxial pipe is being used. Because of the unique burner and pipe designs, the coaxial chimney’s surface receives very little heat.

Which is preferable, a boiler or a gas convector?

Everything is dependent upon the building’s technical features and operational quirks. Convector installation takes less time and material resources.

Heating with a gas convector – the principle of operation and features

A gas convector can enhance the interior design.

The issue of heating is among the most urgent ones given the size of our nation. Some parts of the world experience frigid winters for up to nine months of the year, and summers are so brief and chilly that you occasionally need to turn on the heat in the summer. For this reason, selecting heating equipment is a crucial decision. Luckily, the current market provides multiple solutions to address this type of issue simultaneously. Gas heating convector installation is one of the easiest and least expensive solutions; it is commonly represented by the simultaneous products of multiple manufacturers.

Working principle

These heating devices work on the basis of convection, which is the deliberate upward movement of heated air and the subsequent arrival of cold air. The air in a closed room flows in a circle due to continuous heating.

Long recognized, convection is still utilized in a wide range of technical applications, including microwave ovens for homes and commercial heat removal complexes. Too many to mention in the time or space available. Just to refresh your memory, convection can occur naturally or be forced.

The first happens on its own because of the amazing ability of heated air to expand. The air flow simultaneously flows upward, against the direction of least resistance. Cold air quickly replaces the left heated air mass, rising higher as it warms up and creating space for more cold air, and so on.

However, natural convection is frequently insufficient. The air exchange process is then sped up with the aid of pumps or fans. Forced convection is another name for enhanced convection. The air cannot be sufficiently warmed by a single heat source to organize it. To speed up the air exchange, an electric line must be connected to the unit. Thus, the earlier gadgets are more affordable, easier to use, and energy-efficient. The latter ones, however, are more focused and swifter.

The two-circuit heating boilers that have gained a lot of popularity recently also operate on the principle of natural convection. They work by transferring heat energy from the gas heater to the water in the pipes, an intermediary carrier. And already, the room was heated by water-filled pipes that were connected to radiators.

Heating without coolant

The use of a gas convector for heating does not require the existence of intermediate thermal energy carriers. A solution like this lowers energy losses while also removing the need for the gas pipeline, which is the single point of communication. But it’s really not necessary.

The majority of contemporary convectors are designed to function flawlessly with both natural gas and liquefied propane-butane, or "bottled gas," as a fuel.

Unpretentious versatility

This heating appliance is appropriate for large homes and apartments.

Because of its understated design, the gas convector is a versatile heating tool that can be used in remote and inaccessible locations. Furthermore, the gas convector is the most economically advantageous option due to the low cost of natural gas and its industrial substitute. In actuality, compared to electric heating devices, the use of pricey electricity—which is one of the most expensive energy carriers in remote locations—will be minimal even if you utilize a convector with forced blowing.

Generally speaking, gas convector drawbacks consist of:

• Use of open flame – oxygen is consumed to maintain combustion, and this is a common feature of absolutely all gas appliances.
• The need for regular monitoring of flame combustion – unless there is a built-in electric gas leakage control system.
• Impossibility to organize hot water supply with the help of such devices.
• Impossibility of creating a heating system for several rooms – each convector must have its own source of gas.
• Quite large size and lack of possibility to mount the heating element in building structures.

Apart from the previously mentioned benefits, the gas convector possesses an additional crucial attribute: it is not susceptible to freezing. Gas does not fear frost if water in a cooled pipe freezes at 0°C already. When heating is not used continuously, this feature is most beneficial. For instance, in short-term and intricate constructions such as a garage, a watch, a summer home, and other comparable locations. Although a person does not reside here permanently, it is vitally necessary to have the ability to raise the temperature of the air to a bearable level when they do.

Convectors for gas heating are not very common. However, there are situations in which using them is the best way to create a suitable microclimate.

Gas convector

These days, a range of equipment and heat sources are used to heat spaces for any purpose. Every conceivable design and principle of operation—from gas boilers to electric heaters to geothermal energy—is covered. The gas heating convector is one type of this variety. With the exception of size, this device looks like a regular radiator and runs on either main natural gas or liquefied gas. Heat from the combustion of gas enters the room instantly through the heat exchanger, instead of heating water and then distributing it to radiators.

It’s fascinating to learn about the characteristics of this kind of heater and assess how far it can be used given the benefits and drawbacks of the gas convector.

Purpose

Convector using natural gas to heat a space for a variety of uses. In this instance, combustion occurs inside a sealed chamber that receives air from the street and releases the combustion byproducts. The body of the combustion chamber and heat exchanger absorbs the heat released during fuel combustion, which is subsequently transferred to the room’s air. Rapid heating causes the air to rise, creating space for cooler air and ensuring that convection continues actively throughout the space.

In these circumstances, a gas convector is a great option:

• Basic heating of a small room or house with one or two adjoining rooms.
• As a replacement for a solid fuel stove, which was previously used to heat the house.
• For quick heating and maintaining a comfortable temperature in a garage, utility room, small country house.
• As an addition to the central heating system in rooms where the installation of a water radiator is difficult (basement and semi-basement, attic, veranda, etc.).п.).
• For heating a greenhouse.

Only small homes or single rooms can use gas convectors as a main heating replacement. Based on the available gas convector models, the effective heated area can be computed with ease in terms of capacity. Devices with a capacity of 2.5–6 kW are more frequently found in sales; 12 kW devices are less frequently found. In the first scenario, a room up to 50 m2 can be adequately heated by the convector. The most potent versions are only needed for public and industrial spaces up to 100 m^.

Device

The way a gas convector operates

The gas convector’s design is extremely straightforward and includes:

• combustion chamber;
• gas burner;
• automation unit (Eurosit);
• heat exchanger forming the outer part of the combustion chamber;
• coaxial chimney.

The type of combustion chamber is closed. Both the air supply and the combustion products are released into the street. There aren’t many convector models with an open burner, but it’s best to stay away from them because they quickly exhaust the oxygen in the space and fill it with CO2 and other combustion byproducts.

The heat exchanger’s and combustion chamber’s material:

Steel combustion chambers are less expensive and lighter. The weight of the convector with steel filling is 10–15 kg less than that of the cast iron version. But even with a unique heat-resistant steel used by the manufacturer, it eventually burns out and has a shorter service life.

The lifespan of a cast iron combustion chamber is practically infinite; its sensitivity is limited to abrupt temperature fluctuations. Based on the appearance of microcracks in the material. Other than that, cast iron has a high heat capacity, is resistant to corrosion, and does not thin when exposed to open flames—all of which are advantageous qualities for a heater.

To guarantee uniform combustion over a dispersed area, the convector employs a single-module burner with a straightforward shape. It is crucial that each nozzle has a tiny flame torch and that the gas mixed with air in a specific amount burns entirely and cleanly.

Natural gas is intended for use in gas convectors in accordance with GOST 5542 low pressure 1274 Pa. Convectors frequently assist the installation of a cylinder with liquefied gas at the same time. The cylinder is supplied with gas through a joker and reducer. Mechanical automation, usually using the well-proven EuroSit, is responsible for controlling the temperature in the room, the output power, and the gas supply.

The chimney is shown as a coaxial pipe, which is made up of two distinct channels formed by inserting a smaller-diameter pipe into a larger-diameter pipe. To keep the gas burning, fresh air from the street is pumped through the space between the pipes and the combustion products are released through the internal duct. It is acknowledged that the convector is situated close to the street’s edge. The prepared channel allows the chimney to exit the building immediately outside. The chimney should be as short as possible.

The heat exchanger heats quickly and actively, reaching temperatures of up to 600°C, but more often than not, its surface is built with enough convection flow to sustain temperatures between 60 and 120°C.

Using a supercharger, a fan that can swiftly push a lot of air through the convector, is one way to actively and rapidly remove heat from the heat exchanger and warm up the heated room at the same time.

For example, this method works well for heating a garage, summer house, production or construction area, or utility room. where it is typically cold and, if needed, quick action is taken to create comfortable surroundings for people. If the convector serves as the primary heat source, the fan will only run partially during the process until the air reaches the desired temperature, at which point it will switch off and not run again.

It is appropriate to discuss the most compact convectors independently. The fan is constantly in use in these. In order to minimize the weight and size of the heat exchanger, its area is reduced. Additionally, in order to attain the necessary heat output, a fan is required to have enough time to remove heat from the combustion chamber.

Pros and cons

A convector cannot completely take the place of a gas heating boiler. It is only in certain situations that its use makes sense. The benefit of the convector is that installing gas pipes—which come with a significant risk—will replace the necessity to install water heating pipes throughout the home.

Given that they are less expensive than gas boilers, one or two gas convectors might be a better option for a small home. The costs associated with installing pipes are about the same, but heating radiators are not necessary.

Even though the room was initially cold, the main benefits are the heater’s easy start and quick heating of the space.

Among the crucial characteristics of gas convectors to take into account are:

• The high temperature of the heat exchanger causes the decomposition of dust in the air, which requires constant ventilation so that the occupants" well-being is not impaired.
• Active convection flow covers the entire volume of the room.
• Since the convector is installed one per room, there is inevitably a noticeable temperature difference directly near the heater and away from it.
• To install a convector requires drilling a hole in the wall for the chimney and gas pipe, which affects the appearance of the building and is not always possible.

The convector should ideally be placed beneath the window opening. The chimney can be installed here more easily by drilling a hole in the wall, and the heater’s heat will create a heat curtain for the window. At least 30 centimeters should separate you from the opening’s extreme points, and at least 15 centimeters should separate you from the floor.

The dimensions and a plan for distributing the chimney and connecting the gas pipe are specified in the instructions. It is preferable, nevertheless, to take off the heater’s protective cover while it is still in place, adjust the real values, and move them to the installation location. You’ll need two or four heater mounts. They are already used to measure the location of the chimney’s through hole.

The coaxial chimney is placed and sealed after the hole has been prepared. If the house’s walls are composed of material that could catch fire, a larger hole is dug and fireproof heat insulation is installed around the chimney. Wool with basalt is a great option.

Only workers in the gas service industry are capable of installing gas pipes and connecting convectors. More focus and proper authorization are needed for these works. Installing a shut-off valve and bringing the pipe no farther than half a meter to the convector is sufficient. Using a flexible hose makes forming the remaining area easier. This makes it possible to disassemble the heater if needed.

The operation of a gas convector heater. enhanced convector. Installation method for convectors, as well as their benefits and drawbacks.

In understanding how a gas convector works, it"s essential to grasp its fundamental principle: heat transfer through convection. Unlike traditional radiators, which rely on heating the air directly, a gas convector heats the air through a process where cool air enters the unit, gets warmed up by a heat exchanger, and then circulates back into the room. This warm air rises, creating a natural flow that spreads heat evenly throughout the space. Meanwhile, the cool air is continually drawn in, creating a continuous cycle of heating. This efficient method not only warms the room quickly but also maintains a comfortable temperature with minimal energy consumption. So, the next time you turn on your gas convector, remember it"s the power of convection at work, ensuring your home stays cozy and warm.

Gas convector – what it is, how it works and what it consists of

One type of self-contained heater intended for heating individual rooms is the gas convector. Its operation is nearly the same as that of its more widely used electric counterpart, but the energy source is liquefied or natural gas. [contents h3 p]

How convector works

The way a gas convector works is based on how a gas’s characteristics change as its temperature rises.

Mounted convector for gas

The air rises higher, gets heated, and becomes lighter as it passes through the convector’s heat exchanger. New, cold air segments replace the heated air. The device’s name, convection, refers to this movement of air layers.

The placement of this heater is clearly determined by its internal design and operating principle: the convector is best installed as low as possible to maximize its efficiency.

The coldest air is always at the bottom because of its density and heavier weight, so when it gets heated in this configuration, it gets heated first. In actuality, heat losses are typically maximized under windows, so installing a gas heating unit there is most frequently attempted.

The fundamentals of how a gas convector works

A tangential fan is frequently included with the gas heater. The installation aids in boosting the rate of heated air supply and greatly quickens the room’s heating process. Furthermore, some pricey models have thicker housing walls, which allows them to retain a lot of heat and radiate it into the surrounding area. These units offer the best heating quality by fusing the benefits of convectors and traditional radiators.

Gas convector device

Typically, a gas convector is made up of the following parts:

• housing;
• heat exchanger
• gas burner;
• combination valve;
• combustion products exhaust system;
• thermostat;
• automation system.

Certain components may be made differently or not at all, depending on the kind and functionality of a given device.

The gas convector’s body serves both aesthetic and protective purposes. It is often composed of sturdy metal and coated with a unique heat-resistant paint that both prevents corrosion and can tolerate sudden temperature swings. Since gas is continuously burning inside the device while it is operating, the room’s interior needs to be reliably protected from open flames by the casing. The housing’s upper and lower sections each have unique air-circulation slots.

The heat exchanger’s job is to swiftly and effectively heat the air. As a result, the surface area in contact with the air flow must be maximized. Its surface is as ribbed as possible in order to achieve this. Simultaneously, because the heat exchanger’s principle of operation assumes that the gas flame will always be heating it, it is constructed of cast iron or steel that can withstand heat and has a heat-resistant dye applied to it.

The burner’s gas combustion produces the heat required for a gas convector to function. It typically consists of two parts: the ignition and the main part, and it is housed inside the heat exchanger. The ignition burner is connected to an electrode, which uses a piezoceramic or electronic discharge to ignite it. The primary burner ignites if the automatic system hasn’t shut off the gas supply because of a component failure.

By installing a combined gas valve, the convector’s combustion chamber’s gas pressure can be controlled based on signals produced by the automation system or thermostat. As a result, the fuel supply to the convector is increased, decreased, or stopped entirely by the valve.

Natural draft and forced draft gas heaters are the two categories into which they fall. Additionally, there are various configurations for a gas convector:

• Fireplace-type appliances draw air from the room and the combustion products are discharged into a vertical chimney, i.e. the chimney is located in a vertical chimney. е. their principle of operation is similar to that of an ordinary stove.
• Parapet heaters are more environmentally friendly and safer. Air intake and flue gas discharge in them is carried out through a coaxial pipe, which is laid through the outer wall to the street. The draught in this case is maintained by the built-in fan.

The majority of manufactured convectors operate in accordance with the second scheme, which offers more user comfort and ease of installation.

To protect the device from foreign objects and extinguish the flame, the chimney pipe is led out horizontally at a distance of 50 to 120 mm, contingent upon the convector power and the diameter of the outlet pipe. The chimney pipe is closed with a grate.

Like any other contemporary heater, a gas convector can keep the room at a certain temperature. A thermostat is used for this, and it regulates how the gas valve operates. In the event that the target temperature has been attained, the gas supply is reduced to a level that is still adequate to sustain it.

Inbuilt automation evaluates sensor data and keeps an eye out for any anomalous circumstances. The convector shuts off instantly due to a number of issues, including a drop in gas line pressure, an air supply to the combustion chamber, a malfunctioning gas duct fan, a flame failure, and others.

Peculiarities of installation

Typically, installing a gas convector doesn’t present any significant challenges. Making sure all connections are tight and drilling the proper hole in the wall for the coaxial chimney are the two main tasks. This work is typically broken down into multiple phases:

1. Selection and preparation of the place of installation. As we have already mentioned, it is best to hang the convector under the window. These requirements are contained in building codes and regulations (SNiP). After determining the exact position of the body, it is necessary to mark the place for the exit of the gas duct pipe;

To accommodate an insulation layer, the diameter of this opening needs to be marginally bigger than the pipe’s exterior diameter.

There should be a small slope in the opening.

• Installationconvector and gas duct. The coaxial pipe is assembled and put on the outlet pipe. All joints are treated with heat-resistant sealant. The convector is fixed on the wall with the appropriate fasteners; Installation of the gas exhaust pipe
• Gas supply. The gas pipe should approach the place of installation of the heater only along the street. A shut-off valve must be installed at the point of connection to the convector;
• Test run. Open the gas supply and immediately check the tightness of the connections. To do this, use a soft sponge soaked in soap solution. In a properly assembled assembly, no bubbles should form when applying the solution;
• If everything works normally, light the burner, check the height of the gas flame through the viewing window and set the desired temperature on the thermostat. When this temperature is reached, the convector should switch to a less intensive combustion mode, which is necessary to maintain a comfortable level of heat in the room.

An excellent option for heating rooms with a gas supply is a gas convector. Its installation is easy to do and doesn’t require intricate calculations or pipe routing. It might be the best choice if there is a need for sporadic, short-term heating.

What makes up a gas convector, how it operates, and the proper way to install it.

Component	Function
Gas Burner	Heats the air by burning gas.
Heat Exchanger	Transfers heat from the burner to the surrounding air.
Fan	Circulates the heated air throughout the room.
Thermostat	Controls the temperature by regulating the gas flow.

An easy and efficient way to heat your house effectively is with a gas convector heater. You can choose wisely when adding them to your heating system if you comprehend the fundamentals of how they work.

The burner, which ignites natural gas or propane to produce heat, is the central component of a gas convector heater. After that, the heat is transferred to a heat exchanger, a metal part with tubes or fins that swiftly absorbs the heat and radiates it throughout the space. This warm air is dispersed evenly throughout the room by the convector’s fan, which maintains a constant temperature.

The rapid heating of gas convectors is one of their main benefits. Gas convectors heat a space almost instantly, in contrast to traditional central heating systems, which can take some time to warm up. This makes them perfect for quickly warming up chilly spaces or for adding extra warmth to particular areas of your home.

Gas convectors also provide flexible installation options. You can maximize space and customize your heating setup to meet your needs with their easy mounting on walls and floor placement. They are a well-liked option for both commercial and residential applications because of their adaptability.

The energy efficiency of gas convectors is an additional advantage. Compared to other heating systems, they can aid in lowering energy consumption and heating costs because of how quickly they heat up and how effectively they distribute warmth. To further increase their efficiency, a lot of contemporary gas convectors have thermostats and timers that let you precisely control the amount and timing of heat production.

To sum up, gas convectors provide both homes and businesses with an easy, economical, and effective heating option. These heaters, which use propane or natural gas as energy sources, quickly and consistently warm your space so you can stay cozy during the winter without going over budget. Gas convectors are a dependable option that is worthwhile to take into consideration, whether you’re looking to replace your current heating system or need a primary heating solution.
