TOP 5 gas convectors

The portable gas convector Nurgaz 310P is heating equipment that can be used to heat small non-residential premises, such as garages or workshops. The rated thermal power of 3100 W is enough to heat objects with an area of up to 31 m². The device runs on liquefied gas and can be connected to cylinders of different volumes: from 5 l to 50 l. To connect the convector to a propane cylinder, it is necessary to use a gas reducer (it is not included in the kit and is purchased separately).

The most important part of this convector is the porous ceramic plate. It functions as a burner and a heating element. Propane from the cylinder enters the plate through a tube and, burning, heats it to a high temperature (about 800 - 1000 degrees). The red-hot ceramics give off heat in the form of infrared radiation. The heating intensity and gas consumption can be changed steplessly using a smoothly adjustable tap.

There is nothing “extra” in the design of the device: no electronics, no complex automation. There is not even a piezoelectric element, so the flame is ignited using matches or a lighter. The frame and support leg are a pair of tubes welded into a rigid structure and painted with powder paint. A simple mechanism allows you to install the burner in a vertical, horizontal or inclined position, directing IR radiation to where heating is required.

Due to its extremely simple design, the Nurgaz 310P gas convector is an inexpensive device that allows you to heat a room with minimal costs.

The Zilan ZLN 2830 convector is an autonomous heating device that does not require connection to an electrical network or gas main. It runs on propane from a cylinder that is installed inside the device body and connected to the burner through a reducer. The convector has wheels that rotate 360°, so the user can easily move the equipment to the workplace or to any point in the room where heating is required.

The main working element of the heating device is a ceramic panel consisting of three separate plates. Due to the porous structure, each plate is, in fact, a micro-torch burner that burns gas fuel very efficiently. At the same time, the ceramics are heated by the burning gas to red and give off its heat to the surrounding space in the form of infrared radiation.

The Zilan ZLN 2830 gas convector is equipped with a piezoelectric element, which provides simple and reliable ignition of the flame, and a heating mode switch. Depending on the need for heat, the user can select a mode with a thermal power of 1400, 2800 or 4200 W. The manufacturer claims fuel consumption at the level of 300 g of propane per hour when operating at maximum power.

Like other devices operating on the same principle, this propane convector is recommended for use in rooms with exhaust ventilation or at least the possibility of good ventilation. The safety of the equipment is ensured by a built-in valve that shuts off the gas supply and turns off the fire when the convector is overturned.

The Volteno VO2821 gas convector is a heating device with a ceramic heating element. It heats not the air, but objects and items that are in front of the front panel. Unlike electric infrared heaters, this device runs on liquefied gas - regular propane (SPBT), which can be bought at a car gas station. A propane cylinder with a volume of up to 25 liters, containing 11 kg of propane-butane mixture, is installed inside the convector body. The device is immediately equipped with a hose and a reducer, which reduces the gas pressure to the required level. The wheels attached to the body allow you to freely and effortlessly move the convector within the workshop or shop without lifting it.

The ceramic panel consists of three separate segments, each with a thermal power of 1400 W. They are switched on sequentially, one after another, using a rotary switch. Thus, the user has three power modes: 1400, 2800 and 4200 W. Each segment is a porous (perforated) plate that functions as a micro-torch burner. Gas fuel, which comes from the cylinder and is ignited by a piezoelectric element, burns on the perforated plate and heats the ceramic to a very high temperature. Despite the fact that propane burns almost completely, it is necessary to provide good ventilation in the room or at least open the window for ventilation. Even taking into account the fact that the device is equipped with overheating protection, it is strictly not recommended to leave propane convectors unattended for a long time.

In general, it can be said that the Volteno VO2821 convector is a simple and quick solution for heating rooms with an area of about 40 m².

The Canrey CHC-3 gas convector, with a nominal thermal power of 3000 W, is recommended for heating rooms up to 30 m². It is equipped with a stainless steel burner and Italian Eurosit gas automation. Using the rotary knob, the user can set the desired air temperature within the range from 18 °C to 38 °C. The convector automatically maintains a stable microclimate in the room due to the presence of a thermostat and temperature sensor.

This device can operate on natural or liquefied gas. Reconfiguration from one type of fuel to another is carried out by replacing the injectors of the main and pilot burners (nozzles are included with the equipment). When operating on methane from the gas main, gas consumption does not exceed 0.33 m3/h, and operation on propane is more economical.

The convector has a closed combustion chamber. That is, the air required for fuel combustion is taken from the outside, and flue gases are discharged there. Thus, the operation of the heating equipment does not affect the air quality in the room. To install the converter, it is necessary to drill a hole in the wall with a diameter of 150 mm for a coaxial chimney. The connection of the gas main or propane cylinder is carried out through a nipple with a G 1/2 thread, which is located on the right "side" of the device.

Please note that the Turkish manufacturer uses two names to designate this model of heating equipment: Canrey CHC-3 or Canrey CHS-3 (both versions are available in online stores). You can also find the Canrey CHC-3T version on sale - this is exactly the same device, but additionally equipped with a built-in fan, which provides intensive air circulation for accelerated heating of the room. A convector with a fan is slightly more expensive and requires connection to a 230 V network, and the standard version is completely independent of the presence of voltage in the outlet.

The gas convector "Zhytomyr-5", which is produced in the city of the same name, has a power of 4000 W and can provide good heating of a room with an area of about 40 m². Its steel heat exchanger, welded from sheet metal 3 mm thick, has a "double" design (that is, two chambers and three heat transfer surfaces). An additional heat exchange section allows to reduce heat loss and significantly increase the efficiency of the equipment (in comparison with simpler convectors). Due to this design, the efficiency of the device reaches 90% - that is, almost all the heat is spent on heating the room, and does not "fly out the pipe".

This convector is equipped with Italian gas automation SIT and micro-torch burners Polidoro. A sensor is fixed on the casing, with the help of which the thermostat automatically maintains the required air temperature in the room. In case of emergency situations (overheating of the convector, flame extinction or drop in gas pressure), the automation shuts off the fuel supply, turning off the device.

A huge advantage of the Zhitomir-5 KNS-4 convector is the ability to operate on different types of gas fuel. When operating at maximum power on natural gas, the device consumes 0.65 m3 of methane per hour of operation, and when operating on liquefied propane, the consumption does not exceed 0.24 m3/h. Sets of nozzles required for conversion from one type of fuel to another are already included in the convector kit (note that nozzle replacement must be performed by certified specialists).

The equipment is stationary and is mounted on the wall at a height of at least 0.5 m from the floor. For installation, it is necessary to make a hole in the wall with a diameter of 230 mm to bring out the telescopic pipe of the smoke-air unit (it is suitable for mounting the equipment on walls with a thickness of 240 mm to 540 mm). Due to the sealed combustion chamber and coaxial chimney, the heating device does not burn oxygen in the room (air is taken from the outside) and does not increase the level of carbon dioxide (all combustion products are emitted outside the wall).

The gas convector "Zhitomir-5" KNS-4 is energy-independent, since it does not require connection to the power grid. But if there is a socket in the room that is heated with this device, then you can "tune" and install a fan in order to increase the intensity of heat exchange and significantly speed up the process of heating the air. The fan is not included in the kit, but you can buy it in online stores that sell Atem heating equipment.
