1. Apparatus for transferring heat stored in a fluid from a supply line to a consunner, with a supply forward flow means (67.1'), return flow means (67.3'), collector forward flow means (67.12") and return flow means (67.32"), as well as optionally by-pass (63) and/or safety line (63.2), characterized in that at least partly interesecting longitudinal and transverse lines (13, 13, 43, 43, 63, 63) are provided in a cast ingot, that the lines are connected with one another at least at some of their crossing points without interposed branch pipe parts, that confining walls (23, 33, 73) are provided in the lines (13, 13, 43, 43, 63, 63) and have a longitudinal portion extending parallel to the line direction and that the cast ingot is constructed as a variable matrix (11, 61), in that closable passages (23, 33, 73) are constructed in longitudinal portions of the confining walls (23, 33, 73) and in an adjacent outer wall a closable opening (21, 31, 71) is aligned with a passage (23, 33, 73), the diameter of the opening being at least as large as that of the passage (23, 33, 73). |
