PROBLEM TO BE SOLVED: To provide a floor heating panel for which execution cost was largely saved in constructing an electric floor heating system by directly attaching known heater panels or last attached heater panels to concrete slab surfaces, and which is helpful for its recycling and sorted trash collection. SOLUTION: The floor heating panel B1 is used, which has recessed grooves 53, 54 formed on its back to accommodate a power cable 22 extending from a last attached heater panel A2. The floor heating panel B1 comprises a wooden base material 50 and a buffer material 60 laminated on its back. Easy-to-break lines 61, 62 are formed along an area 65 which will become recessed grooves 53, 54 for accommodating the power cable 22 within the back buffer material. Grooves 53, 54 can easily appear by removing the back buffer material along the easy-to-break lines 61, 62 if necessary. COPYRIGHT: (C)2006,JPO&NCIPI
