Jun 10, 2020 · Thermal stress or thermal shock, also known as thermally induced stress cycling, occurs when your boiler undergoes a rapid change in temperature, such as when cold water flows into a hot boiler. The contrasting water temperatures cause the boiler's furnace to become a different temperature from that of its outer shell, which is the larger area that holds the water and steam.
