A study on the thermal response characteristics of the floor of hydronic floor heating systems

Many studies have been performed on floor heating systems. However, there is almost no data on the response characteristics immediately after the start of the operation. In Japan, floor heating systems are often intermittently operated, so these response characteristics are important. In this research, the heat transmission response, the heat absorption response, and other response characteristics are simulated just after the start of the operation using a twodimensional heat conduction calculation. This calculation was performed using the finite element method. Moreover, the characteristics of the two-dimensional floor model were compared with the commonly used one-dimensional floor model.
