Vacuum Steam Heating: Time for a Comeback? - HVAC Coverage

At the beginning of the heating cycle, the vacuum pump creates a 10-18 inches mercury vacuum in the system so water in the boiler evaporates at a lower temperature and evenly fills the system. Steam pressure continues rising, and eventually the system operates at a regular pressuretrol setting of 1-2 psig to prevent air leakage into the system.

Chapter 10 Boiler Feedwater Deaeration | SUEZ

1. a vacuum is applied to the system and the unwanted gas is vented 2. a new gas is introduced into the system while the unwanted gas is vented Vacuum deaeration has been used successfully in water distribution systems.
