PROBLEM TO BE SOLVED: To effectually lay a floor heater over the entire surface of a floor etc. in a room by forming the base by connecting a first base body and a second base body each having a pair of connection structures each connectable with the neighborhoods of opposite edges. SOLUTION: A second base body 3 is provided which has the same internal structure as that of a first bas body 3a and which is adapted such that a pair of connection structures 9 composed of a female terminal 9a and a male terminal 9b are provided and distributed to the neighborhoods of adjacent edges 8 at the same distance from the adjacent parts. Each of the pair of the connection structures 9 is free to be accommodated in a recessed part 3e formed in an upper surface part 3d of each of the first and second base bodies 3a, 3b whereby the first and second base bodies 3a, 3b are made parallely connectable with each other in order through the connection structures 9. Hereby, a floor heating apparatus can be effectually laid over the entire surface of a floor, etc., in a room. |
