What it is

The high temperature condensate collector is a Potterton Commercial spare part, part number 5142373. It collects and handles condensate produced within the boiler's flue gas path, where the temperature of the condensate is higher than in a standard condensing circuit. It is used on Potterton Commercial Sirius 2 and Sirius 3 appliances.

Signs this part needs replacing

  • Condensate leaking from the collector body or its joints
  • Water pooling around the base of the appliance instead of draining away
  • Visible cracking, distortion or heat damage to the collector
  • Blockage or restricted flow through the collector, causing condensate to back up
  • Boiler lockout or fault codes linked to condensate disposal

Before you order

  • Confirm the appliance model matches one of the Sirius 2 or Sirius 3 variants listed above
  • Check the existing collector for the part number 5142373 before removal
  • Inspect the condensate trap, pipework and flue components at the same time, as faults elsewhere can mimic a collector problem
  • Verify the installation is a high temperature condensate application, as this collector is specific to that duty
