This research is a numerical investigation of the thermal performance of the floor heating system integrated with metallic bridges. For this goal, aluminum and galvanized metallic bridges with 0.5 mm thickness were embedded within the free space of the pipes. Two different bridge lengths of P/S=1/3, 2/3, and 1 were studied in this paper in which P and S are the bridge length and free space between two adjacent pipes, respectively. On the other hand, for the floor heating system, two water fluid temperatures of 40C and 50C were considered. Several results have been obtained in this study. For example, thermal performance of the floor heating system enhances with maximum 12.82% and 6.41% for 40C and 12.88% and 6.43% for 50C using metallic bridges in comparison to the conventional case (without metallic bridges) in which the rate of heat transfer enhancement of heating panel using the aluminum bridge was 6.05% higher than that of galvanized bridge. Additionally, by increasing the bridge length from P/S=2/3 to P/S=1, the thermal performance of the floor heating system increases up to maximum 7.04%.
