Boiler - Wikipedia

Boilers generally have 2 or 3 pressuretrols: a manual-reset pressuretrol, which functions as a safety by setting the upper limit of steam pressure, the operating pressuretrol, which controls when the boiler fires to maintain pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which controls the amount of fire.

AFUE - Single Pass vs Triple Pass Boiler. ? — Heating Help

The point is that AFUE is a fictitious number. It clearly comes down to the system efficiency. Now let's look at stack temperatures. What is the stack temp on a pin style boiler versus 3 pass ? You can resonably expect to see 75 - 100 degrees less on 3-pass boilers. That in itself adds to system efficiency. Just my 2 cents worth
