Vacuum Breakers: Steam and Steam Heat Exchanger Basics

Jan 23, 2017 · Steam-to-water convertors, or heat exchangers, heat the water in the tubes by condensing steam in the shell. When steam is present in the shell, the steam trap is closed. When the temperature control valve closes, the heat exchanger shell becomes a closed vessel filled with steam. When the steam condenses in this closed chamber, it creates a vacuum.

Sooty Boilers, Furnaces, Water Heaters: Cause, Problems, Cure

Soot inside the furnace or boiler reduces the transfer of heat into the heating system's water (or air if it's a furnace). Thus the transfer of heat into the building is reduced by soot in the heating equipment. As the soot layer gets thicker less heat is transferred and more of the heat simply continues to go up the chimney instead of into the

Signs and Symptoms of a Cracked Gas Furnace Heat Exchanger

A damaged heat exchanger in a gas furnace is potentially dangerous to a home's occupants and should not be ignored. Broken and leaking heat exchangers are responsible for about 1,500 deaths per year in the United States, and many more people are poisoned by exposure to toxic gasses that go unfiltered by defective heat exchangers.
