1. Lower the Stack Temperature. Lowering stack temperatures may be as simple as a day/night set back that lowers the operating pressure on steam boilers or operating temperature on hydronic boilers when idling at night or on mild spring and fall days.. 2. Install an Economizer. An economizer uses the otherwise wasted hot flue gas to heat feedwater on its way to the boiler.

holes or leaks are more likely to leak water or steam than to suck in air. There are exceptions to this rule though.

When the pump was removed, the low pressure steam line to the deaerator was left in place.

The steam trap is open and does that. Therefore, no pressure builds inside the boiler during the fill cycle. Once the water probe is made, heat is called for. As the burners heat the water, eventually steam heat raises the temperature at the steam trap. It reaches 192° and closes. Further heating starts building STEAM pressure.

Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.
