What it is

The Varem C1018231 Flatvarem is an 18 litre expansion vessel for sealed heating systems. It takes up the volume increase of heated water and helps hold system pressure steady across the heating cycle. The Flatvarem range uses a flat-profile format for installations where space is tight.

Before you order

  • Confirm an 18 litre vessel is the correct capacity for the system volume and operating pressure.
  • Check the pre-charge pressure required for the installation against the vessel as supplied.
  • Check the connection size and the space available at the mounting point before ordering.
  • Isolate and drain the system before removing the old vessel.
