A heat exchange system comprising a housing (66) elongated along a longitudinal axis (x-x) having an upper portion (22) defining an upper zone, a middle portion (23) defining a transitional zone, and a lower portion (24) defining a lower zone, a heat exchange conduit (25) elongated along the longitudinal axis interior to the housing and configured and arranged to transmit a fluid from a fluid input (26) to a fluid output (27) through the upper zone, the transitional zone and the lower zone, a burner (28) configured and arranged to produce combustion flue gases that can flow through at least a portion of the upper zone, the transitional zone and the lower zone, a hot flue gas flow path (35) between the upper zone and the lower zone, a baffle (30) disposed inside of the heat exchange conduit relative to the longitudinal axis and in the lower zone of the lower portion of the housing, and a gas flow diverter (40) disposed inside to the heat exchange conduit relative to the longitudinal axis and above the baffle and at least partially in the transitional zone, the gas flow diverter configured and arranged relative to the heat exchange conduit so as to divert the flue gas in the flue gas flow path into a first flow path (36) outside of the diverter relative to the longitudinal axis and a second flow path at least partially separated from the first flow path by the diverter. |
