What it is

The Hamworthy 531201116 is a secondary heat exchanger seal for Purwell Variheat floor standing boilers. It seals the joint at the secondary (DHW) heat exchanger, preventing water loss and air ingress at that connection. The part is also listed as a Purwell case seal.

Signs this part needs replacing

  • Water weeping or dripping from the heat exchanger joint
  • Visible cracking, hardening or flattening of the seal
  • Scale or corrosion deposits around the sealing face
  • Pressure loss or repeated low-pressure faults
  • Overheating or noise from the heat exchanger caused by air ingress

Before you order

  • Confirm your boiler model against the fit list above
  • Check the part number 531201116 matches the seal being replaced
  • Inspect the sealing faces for pitting, scale or damage before fitting
