Ariston 65114917 By-Pass

65114917 By-Pass

A by-pass is required to ensure a constant minimum flow rate through the heat exchanger and to dissipate heat on pump overrun. All modern boilers are ‘low water content’ and require a constant flow through them to prevent overheating.

This by-pass is a genuine Ariston By-Pass, and is designed to fit Ariston Clas ONE 24/30/38 combination and system gas boilers. It is recommended that only original Ariston spare parts are fitted to their boilers.
