Frequently Asked Questions

Radiant heating is a type of heat transfer that transfers heat from a hotter object to a colder object without the intervention of air and any loss. Heat moves from a hot source to a cold body through electromagnetic waves, and in the meantime, the air molecules are not heated. The simplest example of radiant heating is the heating caused by the sun. Using radiant heating technology is a smart way to transfer radiant energy from a hot source to surrounding objects. The use of radiant heating is one of the common methods for heating industrial halls, sports halls, poultry halls, greenhouses, restaurants, outdoor spaces, etc.

Radiant heating systems can be used to heat halls with high ceilings, such as industrial, sports, repair shops, airplane hangars, open spaces, pavilions, restaurants, greenhouses, and chicken farms.

In the past, the heating of large spaces with a ceiling of more than 6 meters was done with huge costs, but nowadays it is possible to heat large spaces with the use of radiant heating technology.

By using the radiant heating system, open and roofless spaces such as restaurants, pavilions, and terraces can be easily heated and provide a space with an optimal temperature for people’s comfort.

The most obvious example for a better understanding of the convection heating system is heating a room with a heater or radiator. In this system, warmer air enters the room and is distributed throughout the room by moving the hot air during the heating time.

But in the method of heat transfer through radiation, there is no need to heat the air and heat is spread through electromagnetic waves, and these waves are converted into heat after contact with objects, and in this method there will be no air movement. The best example for radiant heating is the heating of the sphere of time through the waves of sunlight.

Radiant heating systems are divided into two categories: low temperature and high temperature. Low temperature radiant heating systems are like tubular radiant heating systems and high temperature radiant heating systems are like ceramic heaters and electric heaters.

Tubular radiant heating systems are divided into two categories: central radiant heating system and local radiant heating system.

The power of local radiant heating devices ranges from 20 to 60 kW and central radiant heating systems from 100 to 300 kW.

Tubular radiant heating systems are divided into two categories: central radiant heating system and local radiant heating system.

The power of local radiant heating devices ranges from 20 to 60 kW and central radiant heating systems from 100 to 300 kW.

The local radiant heating system is a type of radiant heating system that has a small thermal umbrella and the capacity of these devices usually does not exceed 50 kW. To heat large halls, a large number of these devices must be installed inside the hall, and they are mostly used in places where the purpose is to heat certain parts of the hall and there is no need to heat the entire hall space.

Radiant heating systems are produced in three models: Azar, Taban and Fan Tab

The central radiant heating system is a type of radiant heating system that has a wider thermal umbrella compared to the local radiant heating system, and the capacity of these devices ranges from 100 to 300 kilowatts. With the help of this system, it will be possible to heat large halls with one device. The central radiant heating system has only one model known as the radiant heating system

Radiant heating systems are hung from the ceiling or mounted on the walls. If the local radiant heating systems are hung from the ceiling, they are usually placed 5 to 7 meters from the floor of the hall, and if they are installed on the wall, they are usually placed at a height of 1.5 meters to 2.30 meters from the floor of the hall.

The radiant heating system is hung from the ceiling by a chain, and usually each device is connected to the ceiling at 4 points. The approximate weight of each local radiation heating device is from 70 kg to 85 kg.

The difference between local and central radiant heating systems is in the use of these systems. In the radiant heating system, the burner can be installed outside the hall and the radiant band enters the hall, thus the burner supplies the combustion air from the open air and discharges the exhaust in the open air and does not need a chimney. In the central radiant heating system, combustion is done outside the hall, and there will be no risk of explosion or fire caused by the combustion of the burner.

In the central radiant heating system, the branching beam of electricity and gas will not enter the hall because the burner is installed outside the hall, and therefore the safety of the hall will be lost in terms of fire and gas suffocation risks, as well as electric shock. For the reasons mentioned, the radiant central beam heating system is one of the safest radiant heating systems. Gas supervisors and building facility engineers welcome the use of this system in industrial and sports halls.

In the local radiant heating system, the burner is installed inside the hall, and inevitably, the electric cable and gas piping must be carried out to the place where the burner is installed, and doing this causes the gas piping and cabling to spread throughout the hall, and this It greatly reduces the safety of the hall in terms of fire, explosion or gas. Gas inspectors and building installation engineers do not approve the existence of extensive piping and cabling inside large halls, and this is very dangerous.

In the local radiant heating system, it is necessary to connect the chimney to the device, and in many cases, due to the inappropriate location of the device in terms of the implementation of the chimney, it is not possible to install the chimney, and the use of the device without a chimney will cause safety problems for the users of the hall. brought

In sports halls where there is a possibility of the ball hitting the burner gas hose, the use of local radiant heating system in the sports hall is strongly prohibited.

In order to increase the safety of sports halls, plumbing and cabling should not be exposed to the impact of the ball because there is a possibility of the hose breaking due to the impact of the ball with the gas hose, and in case of a tear in the hose, the gas will spread throughout the hall and there is a risk of fire. And people inside the hall will be gassed.

To solve these problems in sports halls, the burner should be installed outside the hall so that the piping and cables are not placed inside the hall. The best heating system for gyms is the central radiant heating system, and by installing this heating system, the risk of danger is greatly reduced.

For heating open and roofless spaces such as restaurants, terraces and gazebos, using a radiant heating system is the best option because heat waves pass through the air and reach the people sitting under the heating system. It is not possible to use heaters and thermal heaters, because no matter how much hot air is produced, it is all wasted due to the lack of a roof.

For open spaces where beauty is more important, it is recommended to use electric radiant heating system. Electric heaters are much smaller and lighter in terms of dimensions compared to gas-burning systems, and they are also easily portable.

Industrial halls usually have a high ceiling and in many cases a ceiling crane is installed inside the hall. It is wrong to use hot air systems, hot air furnaces, blower heaters and jet heaters to heat halls with high ceilings. Because warm air, being lighter compared to cold air, moves towards the ceiling of the hall and colder air moves towards the floor of the hall. In this way, the coldest point will be the floor of the hall and the hottest point will be the roof of the hall. In industrial halls, due to the high height of the ceiling, there is a large temperature difference between the floor and the ceiling of the hall.

To solve the problem of the temperature difference between the floor and the ceiling of the hall, the best way is to use radiant heating systems that radiate heat to the floor of the hall without any loss, and the air of the hall is not mediated, and the heat goes directly to the floor of the hall where people They are working, it is transmitted. In this way, the air is not heated and we will have the highest thermal efficiency with the lowest energy consumption
