A notable feature of modern high-space public buildings is their relatively high interior height and large volume. The indoor height of a general theater, cinema and gymnasium can reach over 10 meters, and the height of some sports venues can exceed 30 meters. With the development of large-space buildings, the air inside many large-space buildings needs to maintain a certain temperature, humidity and cleanliness. So, how should the heating system of such high-space buildings be designed? 
 
The hot water radiant panel installed on the ceiling can use hot water, steam or hot oil as the heating fluid. It has a very low thermal inertia, allowing for all or part of the operation to be interrupted. It has the shortest preheating time based on the external temperature, a low thermal gradient, and continuous and uniform radiation on all heated surfaces. This heating system reduces operating costs. 
 
The perceived human body temperature is the result of the dual effects of average radiant temperature and indoor air temperature. For the hot water radiant plate heating system, under the premise of fully considering comfort, when calculating the indoor temperature, it is generally 2℃ to 3℃ lower than the convective heating method. Moreover, for every 1℃ reduction in the indoor design temperature, energy can be saved by about 10%. At the same time, under the condition of low water supply temperature, Heating water consumes less energy and has less ineffective heat loss during the transportation process. 
 

	Under the dual effects of radiation intensity and temperature, the surface temperature of the indoor floor in the hot water radiant panel heating system is uniform and consistent. Therefore, due to the uneven spatial distribution of air temperature in the room, its impact on human comfort decreases. The room temperature gradually decreases from bottom to top, forming a positive temperature gradient field, which conforms to the theory of "warm feet and cool head" in traditional Chinese medicine. As a result, people's comfort is enhanced. At the same time, since most of the heat in the room is obtained through radiation, the air temperature in the room is lower than that of traditional radiator heating, thus the loss caused by ventilation in the room is smaller.

ECOPAN hot water radiant panel system promoted and sold by Beijing Leadway Power&nbsp;Co., Ltd. provides the same comfort at a reasonable management cost and achieves ideal heating conditions at a lower operating cost. Considering that no maintenance is required and the system remains unchanged for a period of time, it is easy to understand that this is the most economical and cost-effective heating solution for large Spaces with large volumes. 
 
ECOPAN hot water radiant panels can be used for overall heating and heating of specific areas or work sites. Their application scope is very wide, including large shipyards, ship, aircraft and car repair halls, building materials markets, shopping centers, exhibition venues, multi-functional gymnasiums and entertainment halls, and many other large space places.
