### BOILER EFFICIENCY GUIDE - Cleaver-Brooks

The stack temperature of a 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.
