The Andrews E658 Fan is a genuine replacement combustion airflow component designed to maintain the correct supply of air into the combustion chamber and ensure safe expulsion of flue gases in compatible CWH-series boilers. By drawing in fresh air necessary for efficient combustion and pushing exhaust products out through the flue system, this fan supports stable ignition, clean burning and consistent heat output. When a fan begins to fail, boilers may experience noisy operation, ignition faults or safety lockouts, so fitting the correct OEM-specified unit is essential for restoring dependable and safe performance.

This fan is compatible with Andrews CWH model boilers that reference part number E658 in their parts documentation. To ensure correct fitment and reliable operation, always verify the part number on your existing fan or consult your boiler’s service information before installation, as airflow components vary between models and brands.

Supplied ready for direct replacement, the E658 Fan integrates with your boiler’s original mounting points and electrical connections without modification when installed by a qualified engineer. Choosing this genuine Andrews component helps ensure proper combustion airflow, improved ignition reliability and consistent heating performance in compatible CWH boilers.
