摘要： A water heater includes a water tank, a combustion chamber below the tank and communicating with the flue tube, and a flue system. The flue system includes a flue tube, and V-shaped fins that are metallurgically bonded to the flue tube wall to divide the flue tube into four flue chambers extending substantially parallel to the longitudinal axis of the flue tube. The V-shaped fins include radially extending apertures that reduce the thermal expansion of the V-shaped fins with respect to the flue tube to reduce stress at the joint between the fins and the flue tube. The flue system also includes a removable baffle hanging in each flue chamber. The baffles include adjustable turbulation surfaces to control the quality of combustion in the water heater.
