What it is

The Zilmet 1300001200 is a 12 litre Cal-Pro heating expansion vessel for sealed heating systems. It absorbs the expansion of heated system water, helping to keep system pressure within its design range. The vessel is identified by manufacturer part number 1300001200.

Before you order

  • Confirm that a 12 litre vessel suits the system volume and pressure requirements.
  • Check the connection on the existing vessel against the vessel being fitted.
  • Check the space available at the installation point, including any bracket or mounting arrangement.
  • Confirm the system is isolated and depressurised before the existing vessel is removed.
