The Vaillant 0020197028 Fan is a genuine replacement combustion airflow component engineered specifically for use in EcoTEC Plus VU series boilers. This fan draws in the correct volume of air required for efficient combustion and expels flue gases safely through the flue system, supporting reliable ignition, stable burner performance and consistent heat output. When a fan starts to wear, becomes noisy or begins to fail, the boiler may experience ignition issues, reduced performance or safety lockouts, so fitting the correct OEM-specified fan helps restore dependable and safe operation.

This fan is compatible with Vaillant EcoTEC Plus VU boilers that reference part number 0020197028 in their service and parts documentation. To ensure proper fitment and optimal performance, always verify that the part number on your existing fan matches before installation, because combustion airflow components vary between models and configurations.

Supplied ready for direct replacement, the 0020197028 Fan connects with the boiler’s original mounting points and electrical harness without modification when installed by a qualified engineer. Choosing this genuine Vaillant component helps maintain correct combustion airflow, improve ignition reliability and support consistent heating and hot water performance in compatible EcoTEC Plus VU boilers.
