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

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.

How a Water Tube Boiler Works | Miura Ameri

In a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons.
