The Expansion Tank on Your Noritz Boiler

The expansion tank (expansion vessel) gives heated water room to expand, keeping system pressure stable. A waterlogged or failed tank causes pressure swings, repeated relief-valve discharge, and short-cycling.

On Noritz systems — including models such as EZ Series, NRC Series, NRCB Combi — a failing expansion tank often shows up as error 10 air supply or related symptoms. We diagnose it precisely and install the correct genuine Noritz part.
