What it is

The Potterton 7661011 is a heat exchanger rated at 90 kW, used in Potterton Commercial boiler applications. It transfers heat from the combustion side of the appliance into the water circuit, forming the primary heat transfer component of the boiler. It is listed for the Potterton Commercial Sirius 2 range.

Signs this part needs replacing

  • Water or weeping at the heat exchanger body, seals or connections
  • Kettling, banging or rumbling noises during firing
  • Reduced heat output or slow temperature rise on the heating or hot water circuit
  • Combustion readings drifting outside the appliance's expected range
  • Soot, debris or sludge build-up restricting flow through the exchanger

Before you order

  • Confirm the appliance model and rating against the boiler data plate, as Sirius 2 WH90 and WH110 variants are listed
  • Check the part number 7661011 against the identification on the existing component where visible
  • Confirm access and isolation arrangements before removal, as the exchanger forms part of the water and combustion path
