The Worcester Bosch 8737602353 turbine is a genuine OEM airflow sensing component designed to monitor and regulate air movement within compatible Worcester Bosch boilers, specifically models such as the GR8300iW and GR8700iW. As part of the combustion and safety control system, this turbine wheel assembly detects flue or combustion air flow to help ensure that the correct amount of air is entering or exiting the boiler before and during ignition. Accurate air-flow feedback supports reliable combustion, proper burner operation, and helps protect the boiler by preventing ignition under unsafe conditions.

This turbine is compatible with selected Worcester Bosch GR8300iW and GR8700iW series boilers that specify part number 8737602353 in their technical parts documentation. Because compatibility can vary by model year and configuration, it’s recommended to verify fit using your exact boiler model number and GC number before ordering.

Key features of the Worcester Bosch 8737602353 turbine include its genuine Worcester Bosch construction for assured quality and fit, precision engineering to detect airflow accurately for combustion and safety control, robust design suited to repeated thermal cycling and operational demands, seamless integration into the boiler’s combustion monitoring system, and dependable performance when installed by a qualified heating engineer to support safe and efficient boiler operation.
