The Vaillant 0020059002 Casing is a genuine replacement exterior housing panel designed to protect and enclose the internal components of your boiler. This casing restores the neat, factory-finished appearance while shielding sensitive parts such as wiring, controls, heat exchanger and pipework from dust, impact and everyday wear. A complete and undamaged casing also supports safe operation by helping prevent accidental contact with internal parts and maintaining correct airflow around components that require ventilation.

This casing is compatible with specific Vaillant boiler models that reference part number 0020059002 in their parts documentation. To ensure correct fitment and structural integrity, always verify the part number on your existing panel or consult your boiler’s service information before installation, as casing designs, sizes and fixing points vary between models and output sizes.

Supplied ready for direct replacement, the 0020059002 Casing mounts onto the boiler’s frame using original fixing points without modification when installed by a qualified engineer. Choosing this genuine Vaillant component helps restore the protective enclosure and professional appearance of your boiler, supporting safe, tidy and dependable operation in compatible models.
