Expansion Vessels – FAQ
What is an expansion vessel used for?
An expansion vessel absorbs the increase in water volume as it heats up within a sealed heating or hot water system, helping to maintain safe pressure levels and protect system components.
How do I know if my expansion vessel needs replacing?
Common signs include frequent pressure loss, pressure relief valve discharge, or visible corrosion. A failed expansion vessel can cause system instability and should be replaced promptly.
Are expansion vessels specific to system type?
Yes, expansion vessels vary depending on whether they’re used for heating systems or hot water systems. Always check capacity, pressure rating, and system compatibility.
