Abstract

The present article examines a new method of heating from the floor. After introducing this method of heating, its variations and how it corresponds to the process and mechanism of energy release from the human body and the comparison of these two cases were considered. In another part of this preliminary research, the general structure and components of the underfloor heating system and its implementation including the insulating layer and the pipes used were investigated. Furthermore, with the help of simulation software, a room with floor heating was simulated and the thermal comfort parameter was checked.
