Gas convector - what is it, device, principle of operation

A convector-type heating device provides effective heating of the room in which it is directly installed, due to the natural circulation forces of the air flows it heats. Heat is produced in it by a heat exchange module, which in turn is heated by the flame of a gas burner.

The hot air flow leaving the device moves upward, thereby displacing the cold atmosphere downward. The latter, in contact with the heat exchanger, heats up and is converted into rising hot flows. Thus, the cycle is repeated - as a result of which the temperature in the room quickly increases to the desired value. If the device is equipped with a fan, the redistribution of air masses will be accelerated, and the air temperature in the room will reach the set level faster.

Principle of operation

Convectors of this type are often installed for heating in private homes or cottages, as they operate on convenient-to-use cylinders or liquefied gas and are somewhat similar to gas boilers, but have a simpler operating scheme:

• Gas from the cylinder enters the burner and is ignited by the ignition mechanism.
• The resulting flame heats the heat exchanger housing.
• A flow of cold air enters the heat exchanger, after which it heats up and leaves the device through a special compartment already heated.
• If the model is equipped with a fan, the heated air first enters its chamber, and from where it is pumped into the room under pressure.
• Fuel combustion waste leaves the device through a special hood equipped with electric motor traction, through a connection to a double-walled pipe that goes outside the house. Through it, the air necessary for the operation of the burner is drawn in.

This is the general mechanism of operation of a standard gas convector. Some additions and differences in the operating scheme may be present in different models, depending on the device, configuration and equipment.

Device

In the standard version, the convector includes the following main components:

1. Frame. It contains the main elements and a protective system.
2. The combustion chamber. It burns fuel.
3. Gas-burner. It burns gas and heats the heat exchange circuit. Located at the bottom of the camera.
4. Heat exchanger. Provides air heating.
5. Exhaust system. Removes gaseous combustion products outside the room.
6. Control device. Provides fuel supply, controls temperature via thermostat and sensors.

Note! Models with fans heat the room faster and more evenly. However, the presence of such an element is an additional energy consumption and a source of noise. On the other hand, thanks to the fan, overheating of the heat exchanger is prevented, which means the service life of the device increases.

The best heaters for the garage: how to choose and what they are like

There are many electrical heating devices, how to decide which option is suitable for the garage:

• a simple fan heater is a simple and cheap option to quickly warm up the garage, but such a device will not be able to maintain the air temperature;
• oil heater – uneven heating of the room, high energy consumption;
• infrared heater – low consumption of kilowatts and quick heating of a certain area. Suitable for quick engine warm-up;
• gas heaters - you must follow fire safety rules, but the option is quite economical and practical. Suitable for garages without electrical connection;
• convectors for the garage are the best choice, as they quickly warm up the entire area of ​​the room, and the automation allows you to set the desired temperature for constant heating.

What car enthusiasts say about each of these options, and how to optimize energy costs.

Advantages and disadvantages

A convector for heating a house, running on liquefied gas from a gas cylinder, is characterized by the following set of positive qualities:

• Profitability – operation using inexpensively available natural fuel.
• Independence from external highways and gas pipelines.
• High performance.

• Compact equipment.
• Easy installation.
• There is no need for coordination with project documents.
• Intake of air oxygen from outside the building, and not from inside the room.
• Versatility in the choice of fuel - the unit can operate on both propane and methane - to switch you only need to reinstall the burners.
• Large selection from a range of well-known manufacturers.

Despite the large number of advantages, convectors of this type are not without some disadvantages:

1. Low efficiency for spacious rooms.
2. If there is a fan, the device can produce a significant level of operating noise, which reduces the level of domestic comfort.
3. To install the hood you will need to make a hole in the wall of the house.
4. Installation, configuration and initial start-up of the unit requires the involvement of specialists.

On a note! One of the clear advantages of a convector heating device powered by a cylinder is its inertness with respect to temperature changes - the device does not deteriorate when turned off and left in cold weather - which absolutely cannot be done with any gas boiler for the home, since water is often poured into the system when when freezing, it expands and turns into ice.

When is the heater effective?

It is imperative to ensure the garage door is sealed and insulate the floor and roof. If you carry out repairs in the garage in winter, then you can insulate the floor using foam screed or lay a board over the sheathing.

An infrared heater will help to quickly warm up the garage and car, rather than maintaining the temperature; it heats locally.

Criterias of choice

When choosing a convector for specific application conditions, the following main characteristics of the equipment are primarily taken into account:

1. Installation method.
2. Fan.
3. Combustion chamber design.
4. Power and gas consumption.
5. Heat exchanger material.
6. Automation.

Let us consider in detail the features of each parameter.

Installation method

Modern convectors are divided into two types according to installation method:

• Wall mounted . Fixed to the surface of the main wall. They are lightweight and compact in size. The exhaust device is equipped with a rigid pipe through a hole in the wall. Maximum power – 10 kW.

Installation

According to GOST, installation should be carried out under the window space.

1. Forming a through hole for supplying a gas pipe and a hole for the chimney.
2. Preparing holes for mounting the system and installing brackets.
3. Fastening the convector to the wall.
4. Connecting the convector to the chimney and treating the joint with silicone.
5. Connecting the system to the fuel source and treating the through holes with foam to prevent the passage of outside air.
6. Checking the correct installation by responsible specialists and starting the heater for the first time.

Of course, the best option would be to carry out installation by a special team with the appropriate permits to prevent possible errors and waste of time.

Video instructions for measuring gas flow with a convector:

• Cast iron. Sufficiently heat-intensive - able to retain heat for a long time after being turned off. Disadvantages: fragility, heavy weight.
• Duralumin. Strong, lightweight, durable. The downside is that it is quite expensive.
• Copper. Durable, plastic, not subject to destruction. The disadvantage is the very high cost.

A convector with a cast iron heating circuit is most optimal for domestic use. It is durable and retains heat for a long time. However, during installation and operation it is necessary to take into account its increased fragility.

Automation

Convector gas heating from bottled gas can be controlled either by a simple automation system based on a relay and thermostat, or by a more advanced software module that sets many operating parameters. The final cost of the device largely depends on the type of automatic unit used. However, the more factors are taken into account in the settings, the more economical the consumption will be and the more comfortable the living conditions will be.

Finishing

If the kitchen combined with the living room has the same floor covering, then there are no special rules for carrying out the work. When combining different materials, take into account in advance where they will be joined.

For example, laminate flooring creates unsightly joints with tiles. The main thing is that the floor is flat without curved joints, as they will be noticeable.

Kitchen cabinets that are mounted on the walls should reach the ceilings. In some cases, craftsmen “lower” the ceiling with plasterboard.

Briefly about the main thing

A gas convector, operating by burning natural gas from a cylinder, heats the room through natural or forced air circulation. The device includes the following main components:

1. Frame.
2. The combustion chamber.
3. Burner.
4. Heat exchanger.
5. Ventilation system.
6. Control block.

When choosing a gas convector for heating a private home, a number of parameters are taken into account, such as the installation method, the presence of a fan, the type of combustion chamber, power and fuel consumption, the type of material from which the heat exchange circuit is made, and the capabilities of the control system.

The main advantages of a convector running on gas from a cylinder are its economy, ease of installation and maintenance, compactness, and independence from gas mains. Disadvantages - low efficiency for spacious rooms, operating noise in fan models and the need to call a specialist for installation.

Zoning

Designers do not advise giving in to fashion trends and copying design ideas without taking into account dimensions, location and other nuances. Before planning and arranging furniture, every detail is thought through.

There are several simple rules that experts advise you to follow:

• Let the room have natural light. To do this, remove excess walls (except for load-bearing ones).
• If the rooms in the apartment are small (12 sq. m or 16 sq. m), the layout of the kitchen combined with the dining room will be the right solution.
• If the ventilation system is not designed correctly, the smell of food will spread throughout the apartment.

What gas is used

In the original version, the convectors were designed to consume mains gas, which created a false assumption that the installation used only natural gas.

But when using special transition kits, it is very easy to convert it to liquefied fuel. Some device models are already designed for the possibility of transition.

The use of bottled gas has several nuances, including:

• It is economically inefficient to work on liquefied fuel, since the cost is equal to the price of electricity if correctly recalculated.
• There are strict requirements for the installation and operation of equipment. It is better not to deal with the installation process yourself, but to entrust the arrangement to specialists.

Styles

There are many current trends and design ideas. The kitchen-living room in a modern style looks simple and minimalistic.

At the same time, it is not necessary to strictly adhere to any style; you can take its main idea as a basis and cleverly play with it with accessories and other details.
