In recent years, with the increasing emphasis on comfort and energy efficiency, the interest and demand for hot water radiant heating systems has increased significantly.The hot water radiation plate is mainly composed of precision steel pipe, radiation plate (steel plate), thermal insulation material and assembly equipment.To explain it in the simplest way, the piping of hot water circulation heats the surface of the radiant panel.Specially coated panels that are heated transfer their heat through radiation (infrared) to organisms and objects in the environment that need to be heated.


	 


	Unlike conduction and convection, heat from radiation (thermal radiation) has the advantage of being propagated in a vacuum (an airless environment), and this energy is absorbed by the surface of a solid object rather than by air.This means that no energy is transferred to the surrounding air.Infrared waves travel easily through air and space, generating heat only when they hit objects such as the ground or walls of houses.When the thermal radiation emitted by the infrared system hits an object (wall, floor, indoor object), the affected molecules begin to oscillate under the action of the rays.The energy continues to be absorbed by the molecules of the object until the oscillation frequency reaches that of thermal radiation.After this point, the thermal radiation begins to be reflected.Humans believe that this effect is a state of temperature caused by an increase in molecular energy.Thermal comfort is a combination of air temperature and surface temperature.

	Radiation is a natural mechanism by which a cold surface absorbs heat contained or generated by a surface that is warmer than itself.Absorbed heat is heat transferred by thermal radiation.In radiation, the air in the environment does not prevent heat transfer, first the objects in the environment, and then the entire ambient air warms.The Earth is heated by the sun based on this principle.Therefore, when entering an environment heated by radiation, the first feeling is comfort.As a practical example, when moving from a shaded area to an area with sunlight, although the air temperature remains the same, it feels warmer.This is due to the fact that the sensation of temperature is caused not only by the temperature of the air, but also by both the air temperature and the surface temperature.As the surface temperature increases due to direct exposure to sunlight, so does the perceived temperature.


	 


	The hot water radiant panel is modular.The required panel surface area can be obtained by combining the required number of modules of a specific size.In this way, the thermal needs of any space can be fully and accurately met.The interconnected hot water radiant panels not only create the required heating area, but also act as distribution pipes.In this way, it also saves pipe costs and labor in space.Heating the environment by evenly placing radiant panels on the ceiling ensures that the floor temperature is always several degrees higher than the indoor air temperature.This creates a more natural and comfortable feeling of warmth.


	 


	In the heating of industrial facilities, warehouses, gymnasiums, train repair stations, aircraft hangars, amphitheaters, animal farms, greenhouses and similar high-ceiling buildings, the use of hot water radiant panels can save more than 30 percent of energy compared to other systems.Hot water radiant panels have many important functions, especially when considering heating buildings with high ceilings and/or high fire risk.

	ECOPAN hot water radiant panel, promoted and sold by Beijing leadway Power&nbsp;Co., LTD., is the most effective heating system, with high heat exchange efficiency, small temperature gradient, uniform heat and cold, and 30%~50% energy saving than conventional floor heating and convection heating.In addition, due to the low thermal inertia of the ceiling radiant panels, the heating system can only be operated intermittently when necessary, and no other heating system can provide the same comfort at such a low administrative cost.


	 


	ECOPAN develops optimal production solutions that make operations on the construction site easier, optimize time, and thus reduce costs.The side is formed in the board, easy to place the insulation material, the head of the pipe lining is welded perfectly, and the joint cover is easy to position, so that the installation time is shortened.With the same dimensional characteristics (pipe diameter, number and spacing, panel width), ECOPAN panels have a higher thermal output than other products on the market.This allows fewer quantities to be used to meet the same required output, saving on material and installation costs.In terms of investment and operating costs, the hot water radiant panel is basically the same as the traditional convection heating methods such as the radiator, and has a simple and lightweight structure and convenient installation.
