BOILER EFFICIENCY GUIDE - Cleaver-Broo
number of times the hot combustion gasses travel across the boiler (heat exchanger). A boiler with two passes provides two opportunities for the hot gasses to transfer heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer. The stack temperature of a 4-pass boiler will be lower than the stackGet a Quote
