Currently, some high-rise industrial workshops and high-rise public buildings have large amounts of cold air infiltration, large temperature gradients, and higher requirements for indoor temperature and comfort. Traditional heating methods are difficult to meet these needs, while gas radiant heating systems have the advantages of high efficiency, fast heating effect, even heating, high comfort, and can efficiently solve the heating needs of high-rise spaces. Compared with convection heating, gas radiant heating can save 30-50% of energy. 
 

	When convective heating is used, the air in the room is heated and forms a convection of hot and cold air, so the temperature gradient in the room air is relatively large, with the temperature at the top of the room being higher and the temperature near the ground being lower. The temperature gradient for convective heating is generally about 0.5-1.0℃/m. When radiant heating is used, the radiant heat is directly radiated downwards, and some heat is accumulated on the ground, so the temperature gradient in the room air is smaller, and the corresponding heat loss at the top of the building is also smaller.

	When the indoor air temperature is the same, the radiant heat directly radiates to 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, under the condition of maintaining the same subjective temperature in the room, the indoor air temperature of the radiant heating is 2-3°C lower than that of the convective heating. Therefore, the heat consumption is small, and the temperature difference between indoors and outdoors is small, so the amount of cold air infiltration is also small.

The gas infrared radiation heating equipment promoted and sold by Beijing Leadway Power Co., Ltd. has its independent heater installed outside the building, and the radiation pipe section is placed above the heating space, which does not occupy the building's usable space. The radiant heat is directly radiated downwards, and the ground can accumulate some heat. The temperature gradient in the indoor air is small, the heat loss is small, and the heat energy consumption is reduced while ensuring comfort, thereby achieving the goal of energy saving. Its control system can control multiple devices and can be connected to the software on a computer. Automatic control and temperature regulation are convenient, and the temperature in each area can be controlled separately. 
 
IMPRESIND gas radiation heating system operates at negative pressure and has a heating efficiency of up to 95%, ensuring safety, efficiency, economy, comfort, and environmental protection. The product has passed CE certification and has the highest market share in China. It can meet the heating needs of high-ceiling spaces such as industrial workshops, warehouses, aircraft and aircraft maintenance centers, logistics centers, automobile and train/subway stations, etc. Compared with other heating methods, it can not only reduce the initial investment costs but also save more than 50% of the operating costs per heating season on average.
