A remarkable feature of modern tall space public buildings is that the interior height is high and the volume is large. The indoor height of general theaters, theaters and stadiums can reach more than 10m, and the height of some stadiums can reach more than 30m. With the development of large space buildings, the air in many large space buildings needs to maintain a certain temperature, humidity and cleanliness. 
 
Hot water radiant panels mounted on the ceiling can use hot water, steam or hot oil as a heating fluid with a temperature range between 50 and 180°C. Thermal inertia is very low, hot water radiation panel is particularly suitable for industrial halls, offices, stadiums, stores, supermarkets and other tall space heating. This heating system reduces management costs because it allows for complete or partial operation interruption, minimal preheating time depending on the external temperature, low thermal gradient, and continuous uniform radiation of all heated surfaces. 
 

	Human realistic temperature is the result of the double action of average radiation temperature and indoor air temperature. For hot water radiant panel heating system, under the premise of full consideration of comfort, the indoor temperature is generally 2℃ ~ 3℃ lower than that of convective heating, and the interior design temperature can save about 10% energy every time the temperature is reduced by 1℃. Less energy is consumed to heat the water, and less ineffective heat is lost during transportation.

Under the dual action of radiation intensity and temperature, the indoor surface temperature of the hot water radiant panel heating system is uniform. Therefore, since the uneven spatial distribution of the air temperature in the room has a smaller impact on human comfort, the room temperature gradually decreases from bottom to bottom, forming a positive temperature gradient field, which conforms to the theory of "warm feet and cool top" in traditional Chinese medicine, people's comfort is enhanced. At the same time, because most of the heat in the room is obtained through radiation, the air temperature of the room is lower than that of the traditional radiator heating, so the loss of the room due to ventilation is smaller. 
 
The good radiation system of ECOPAN hot water radiation panel promoted and sold by Beijing Leadway Power&nbsp;Co., Ltd. provides the same comfort at such a low management cost and obtains the ideal heating conditions at a lower cost. Considering that no maintenance is required and the system remains the same over a period of time, it is easy to understand that this is the most affordable high space heating solution for heating large volumes, which can meet many high space places such as large shipyards, ship, aircraft and automobile maintenance halls, building materials markets, shopping malls, exhibition venues, multi-purpose stadiums and entertainment halls.
