The embedded radiators compared to conventional radiators, the heat in terms of the principle is the same, but the combination parts are different. The building structure replaces the  radiator shell,  and the heat exchanger is placed in  the building structures, to heat the room temperature. (Such as the geosyncline, steel structure, glass curtain wall, etc.)
Embedded radiator is based on the windowsill special structure, such as office buildings and shopping malls. By the limited space the heat exchanger is placed in its interior,   to heat the room.
