What it is
The Ariston 65120701 is an expansion vessel for the domestic hot water (D.H.W.) side of an Ariston system. It absorbs the pressure rise created as water heats and expands within a sealed D.H.W. circuit, reducing strain on pipework, valves and fittings.
Before you order
- Confirm the part number 65120701 matches the component being replaced.
- Check the vessel is intended for the D.H.W. circuit rather than the heating circuit.
- Compare the connection size and mounting arrangement against the existing vessel.
- Check any pre-charge and system pressure requirements against the appliance documentation.
