PROBLEM TO BE SOLVED: To provide an apparatus for transferring heat into a product, such as a tire, formed at least in part by molding. SOLUTION: The apparatus includes a mold that has a central axis with a forming surface disposed radially outward from the central axis. A heating conduit is included and is at least partially located radially outward from the forming surface of the mold. The heating conduit is configured for use with a gas, such as saturated steam, in order to effect heat transfer to the forming surface of the mold. The heating conduit extends helically with respect to the central axis in order to allow condensed water formed in the heating conduit to be drained therefrom via the force of gravity. A drainage connector may be in communication with the exit of the heating conduit and have a longitudinal axis located below that of the heating conduit to allow condensed water to drain more easily therefrom.
