  • Water heater flue with improved heat transfer
    Patent number: 6957629
    Abstract: A water tank has a central flue to which clips are welded. The clips define baffles and are welded to have a greater heat transfer area where they are joined to the central flue. The individual clips are rectangular and are welded to the flue wall along one side at an angle of 4° rather than the 9° of the prior art so that the clip has a greater weld area. This greater weld area increases the thermal path between the clip and the wall of the central flue.
