As China enters the era of energy shortage, energy saving is an important strategic goal in our country, and energy-saving technologies and products are facing huge market demand. Hot water radiant panel heating not only has the characteristics of green environmental protection, space saving and high comfort, but also can provide efficient and energy-saving solutions in the application of buildings. Radiant heat contributes more to space occupancy, which means that a lower air temperature is acceptable while providing the same level of comfort. If properly controlled, this can save energy and costs. 
 

	Increased ventilation has less effect on the performance of the hot water radiant panel than a convective system, because the radiation component is not affected by the ventilation rate, whereas a convective system must primarily raise the air temperature to maintain comfortable conditions. Examples include areas such as large lecture theatres and lecture halls, where doors may remain open during occupation, allowing large amounts of air to pass through the space.

Shorter warm-up times are often associated with radiative systems because radiative heat transfer directly exchanges heat with the thermal mass of the building. Once the hot water radiant panel temperature is higher than the temperature of the room surface, the building structure will begin to absorb heat. The water content of the hot water radiant panel is lower than that of conventional radiator systems, thus reducing heating uptime for more efficient intermittent use. The hot water radiant panel will have a downward-radiating component of about 60%, maintaining the soffit temperature and preventing cold water. Unlike the shorter wavelength solar radiation that can pass through the glass of a building, the lower temperature, longer wavelength radiation from radiant panels does not pass through the glass and can therefore be effectively used in a room with a glass curtain wall. 
 

	In a building heating system, what matters is the exchange of energy between two objects, not the absolute value of the object's thermal radiation. One advantage of radiation transferring heat is that if the temperature difference between objects is larger, more energy is transferred. Thus, radiant heating can be thought of as self-balancing the heat flow to where it is needed. For example, the surface temperature of the outer wall may be lower than that of the inner wall, so more energy is exchanged to that surface than on a warm surface (the amount depends on the location and surface properties of the material).

ECOPAN hot water radiant panel is made of metal tube sheet, which is prefabricated in the factory into a standard length of 3 meters, 6 meters (special requirements can be prefabricated 2 meters, 4 meters). Each radiant panel can be connected with a quick connector. Each radiant panel and collection pipe is prefabricated in the factory and tested for safety. With the same dimensional characteristics (pipe diameter, number and spacing, panel width), ECOPAN hot water radiant panels have higher thermal energy efficiency than other products on the market. This makes it possible to use fewer products to meet the same heating requirements, saving on materials and installation costs.
