ABSTRACT:
A flexible hosing for circulation of a heat transfer fluid to effect heat exchange within a concrete or other type of slab. An inner wall comprising nylon, rayon or other similar material forms an inner wall of the hosing to resist corrosive attack by the heat transfer fluid. A locator wire is embedded within the hosing for transmission of a locating signal so that the position of the hosing within the slab may be accurately determined. The wire may also serve as an electrical resistance heating element should the heat transfer fluid become frozen, or should it be desired that the heat exchange system be operated without an external boiler or other heat source.
