Single Pass Boilers Vs. Triple Pass Boilers - Marbledale

Apr 17, 2015 · Older, single-pass style boilers run at 500 degrees and run in a single-pass. This means that combustion gases travel the length of the boiler, resulting in an unnecessary loss of heat. New boilers, like the Buderus Boilers, run at 300-350 degrees and pass through 3 "chambers" to efficiently use heat. A 3-pass boiler design is the most […]
