What it is

Potterton 10/19925 is a 12 litre expansion vessel for Potterton Ecotherm appliances. It absorbs pressure changes in the heating circuit as water expands and contracts. The vessel is listed for the Ecotherm EG, EGC, EGCV and EGV ranges.

Signs this part needs replacing

  • System pressure rises quickly when the boiler heats up
  • The pressure relief valve discharges water during heating
  • System pressure drops repeatedly, needing frequent top-ups
  • The vessel does not hold its air charge when checked

Before you order
