What it is

This is the Worcester Bosch 8716855365 Expansion Vessel, a 25 litre vessel intended for the domestic hot water (DHW) side of the appliance. It is manufactured by Worcester Bosch and listed for SC and TC series appliances. Its function is to absorb the expansion of heated domestic hot water within a sealed system, limiting pressure rise at the draw-off side.

Before you order

  • Confirm the part number 8716855365 matches the vessel currently fitted or the one listed for the appliance.
  • Check the vessel capacity and that a 25 litre DHW vessel is the correct size for the installation.
  • Verify the appliance series reference (SC/TC) against the appliance data plate before ordering.
  • Confirm the connection arrangement on the existing vessel matches what is being supplied.
