Connecting piece for a heater connection

摘要

Connecting piece (5) for a heater connection for preventing gravity circulation, which inadvertently transfers heat, in a connecting line of a central heating system that is open to a heater (1). In one embodiment, an insert (9), which is situated in a connecting nipple (6) constructed as such a connecting piece, forms a labyrinthine flow duct (7) with the inner wall of the connecting nipple (6) by means of an integrally formed groove (10). <IMAGE>
