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

    Jan 05, 2017 · 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.Learn More
