Alpha 1.023560 Expansion Vessel 8L with PRV 1.023565

Description

Alpha 1.023560 Expansion Vessel 8L with PRV

The Alpha 1.023560 Expansion Vessel 8L is a replacement expansion vessel designed for selected Alpha CB, CD and HE boilers.

This updated replacement now supersedes older part number 1.015394 and is supplied with compatible Pressure Relief Valve 1.023565.

The expansion vessel helps maintain stable system pressure by absorbing expansion from heated water within the sealed heating system. A faulty expansion vessel can lead to pressure fluctuations, leaking PRVs and boiler lockouts.

Replacing the vessel and PRV together helps restore safe and reliable heating system operation.
