In industrial heating for high-ceilinged spaces, traditional heating facilities have low thermal efficiency, high heat loss, and huge maintenance, repair, and personnel expenses. In contrast, gas radiant heating has extremely small heat loss from fuel to heating stages, and it has advantages such as high efficiency, energy saving, safety and reliability, economic feasibility, uniform comfort, and clean and environmentally friendly. 
 
Gas has little loss during transmission, and the combustion of the radiator is very complete, so the heat of the entire heating system can be fully utilized. In contrast, the traditional radiator heating system has 10-15% of heat loss along the way from the boiler, so the heat efficiency is lower. In the case of the same indoor air temperature, the radiant heat of the gas radiation heating directly irradiates the heating object, and the perceived temperature of the radiant heating is 2-3°C higher than that of the convective heating. In other words, in order to achieve the same indoor perceived temperature, the indoor air temperature of the radiant heating is 2-3°C lower than that of the convective heating, so the heat loss is smaller, and the indoor and outdoor temperature difference is smaller, so the amount of cold air infiltration is also smaller. 
 

	Gas Radiant Heating is a method of heating in which natural gas, liquefied petroleum gas, or artificial coal gas is burned in a special combustion device called a radiation tube to emit various wavelengths of infrared radiation for heating purposes. The infrared radiation emitted by the radiation tube has a wavelength that falls within the range of heating. Therefore, the atmospheric temperature in the building will not cause serious vertical imbalance. As a result, the utilization rate of heat energy is very high, and people feel very comfortable. This has effectively solved the problem of flexible heating in high and large spaces that has long troubled the heating and ventilation industry.

IMPRESIND gas radiant heating system sold by Beijing Leadway Power&nbsp;Co., Ltd. has independent heaters installed outside, while the radiation tubes are installed on the upper part of the heated space in the building, which does not occupy the building's usable space. The radiant heat is directly radiated downwards, and the heat transfer has a strong directionality. The ground can also store part of the heat, the indoor air temperature gradient is small, the heat loss is small, and the heat energy consumption is reduced in order to ensure comfort, thereby achieving the goal of energy saving. 
 
The insulation requirements for the maintenance structure of high-rise industrial buildings are not high. The intelligent control system of IMPRESIND gas radiation heating system can heat on demand, which is not possible with convection heating. It can be flexibly arranged according to different needs, and can provide full heating or local heating in a large space. It can efficiently solve the heating needs of high-precision industrial workshops, aircraft maintenance hangars, railway locomotive maintenance hangars, logistics centers, warehouses, large sports halls, exhibition halls, etc. in high-rise spaces.
