ABSTRACT A concrete floor having a heat transfer pipe embedded therein for circulation of heating or cooling fluid, as well as a method of construction thereof. The method comprises the steps of laying a transportable base section with a pipe secured in the desired configuration to the surface thereof, in the area where the concrete floor is to be constructed. The base section and pipe are covered with a layer of heat conductive granular material such as sand, and cement is then poured over the granular material to the desired floor level. The base section with the pipe secured thereto may be preassembled at a location away from the building site. A concrete floor constructed according to the method of the present invention, since the piping is embedded in sand, enables freer movement of piping during expansion and contraction, and significantly reduces the incidence of material fatigue.
