The Vaillant 0020148383 Gas Section with Regulator is a genuine replacement fuel delivery module designed to precisely control the flow and pressure of gas entering your boiler’s combustion system. This integrated unit combines the gas valve and regulator to deliver accurate, stable fuel supply to the burner across varying heat demands. A correctly functioning gas section supports smooth ignition, efficient combustion and responsive modulation, while built-in safety shut-offs protect against unsafe gas flow conditions.

This gas section with regulator is compatible with Vaillant ecoTEC Plus VUW and ecoTEC VU series boilers that specify part number 0020148383 in their technical documentation. To ensure correct fitment and reliable operation, always verify that the part number on your existing gas section matches before installation, as gas control components vary between models.

Supplied ready for direct replacement, the 0020148383 Gas Section with Regulator integrates with the boiler’s existing gas inlet, control wiring and mounting points without modification when installed by a qualified Gas Safe engineer. Choosing this genuine Vaillant component helps restore precise gas control, improve combustion performance and maintain safe, dependable heating and hot-water operation in compatible ecoTEC Plus VUW and ecoTEC VU boilers.
