The Vaillant 0020195223 Pressure Safeguard is a genuine safety control component designed to monitor and regulate air pressure within the combustion and flue system of your EcoTEC VU or VU series boiler. This device ensures that correct airflow conditions are present before the boiler initiates ignition. If the detected pressure is outside safe parameters—due to blockages, fan failure or flue restriction—the pressure safeguard signals the boiler’s control system to prevent ignition and protect internal components, helping to maintain safe operation and reduce the risk of unsafe combustion.

This pressure safeguard is compatible with Vaillant EcoTEC VU and VU series boilers that specify part number 0020195223 in their technical documentation. To ensure correct fitment and reliable performance, always verify that the part number on your existing component matches before installation, as safety devices and pressure switch settings can vary across models and configurations.

Supplied ready for direct replacement, the 0020195223 Pressure Safeguard integrates with the boiler’s existing tubing and electrical safety circuits when installed by a qualified engineer. Choosing this genuine Vaillant component helps restore dependable pressure monitoring, supports correct combustion airflow and contributes to consistent, safe heating performance in compatible EcoTEC VU/VU boilers.
