Potterton Promax / Gold Heat Gas Valve – Refurbished | Part No. 241900

Ignition failure, unstable flame, or repeated boiler lockout in a Potterton Promax SL, Promax HE Plus, or Gold Heat boiler is a reliable indicator of a failing gas valve. This component regulates gas flow to the burner and is fundamental to safe, consistent combustion — when it deteriorates, your boiler cannot operate reliably. The Potterton Promax / Gold Heat Gas Valve (Part No. 241900) is the pre-owned direct replacement, restoring accurate gas regulation across one of the widest Potterton Heat Only compatibility ranges available — covering Gold H, Gold Heat ErP, Gold FSB, Promax SL, Promax HE Plus, Promax FSB, and Promax SL Heat ErP series, including serial number AC and BC variants.

This pre-owned unit is quality-checked and tested to confirm correct gas flow regulation and safe combustion performance before dispatch. Supplied with a 6-month warranty.
