Vaillant Aqua Sensor 194819

The Vaillant Brass Aqua Sensor (194819) is a safety device for Vaillant boilers, functioning as a switch with an in-built flow sensor installed in the pipework for central heating and domestic hot water systems. When the pump operates, the flow switches detect movement and relay information to the electronic control, allowing the ignition sequence to progress. Its primary role is to ensure the burner cannot ignite while the system is low on water or dry, protecting the appliance.

Housed in brass with an electrical plug, the Aqua Sensor is supplied with clips and O‑rings. This is a genuine Vaillant component designed to support reliable performance and correct operation of compatible heating and hot water systems. It is suitable for Turbomax Plus and Turbomax Pro models and comes with a manufacturer's guarantee.
