Expansion Vessels
Overview
Expansion vessels are commonly used to protect closed water heating systems and domestic hot water heating systems from being exposed to high pressure. Expansion vessels work by being part filled with air, this then protects the system by cushioning any shock which is caused by water hammer and also absorbing any excessive water pressure which may have been caused by thermal expansion.
GMS supply two types of expansion vessel to suit different systems:
- Heating Expansion Vessel
- Potable-Water Expansion Vessel
