What it is

The Siemens RWF50.21A9 is a Siemens control component listed for oil-fired boiler applications. It is identified by the part number RWF50.21A9 and is catalogued under the OIL SPARES — SIEMENS model reference. It is a control item rather than a mechanical spare, so correct identification against the existing unit matters more than physical fit.

Before you order

  • Check the part number on the existing control, its label or the appliance documentation and match it to RWF50.21A9 before ordering.
  • Confirm the control reference required by the boiler or burner installation, as the RWF50 range covers more than one variant.
  • Have the appliance make, model and any burner details to hand so the correct reference can be verified.
