Expansion Vessels

Expansion vessels are small tanks used to protect closed water heating systems and domestic hot water systems from excessive pressure which can become hazardous otherwise. Without an expansion vessel, the water system cannot allow cold water to expand as it is heated therefore creating a dangerous environment.
