4-pass boiler will be lower than the stack temperature of a 2 or 3-pass boiler, of the same basic design, operating under similar conditions. Because of this fact, the 4-pass will have higher efficiency and lower fuel cost. This is not an opinion; it is basic heat exchanger physics. The 4-pass design will yield a higher overall heat-transfer
