Ideal Logic + Combi 24/30/35 Expansion Vessel Kit 177540 – Refurbished

An expansion vessel protects a closed heating system from pressure surges as water heats and expands. A failing vessel is a common cause of fluctuating system pressure, repeated pressure relief valve discharge, or boiler lockouts across the very wide Ideal Logic, Logic+, Mini, MAX, Ultra, and Keston-badged ranges. The Ideal Expansion Vessel Kit (Part No. 177540) is the direct replacement that restores stable pressure control.

This is a fully refurbished part taken from a completely functioning boiler, quality checked by our experienced engineering team. The product might have slight cosmetic marks as it is part of a used boiler, but is fully tested before dispatch. Supplied with a full 12-month warranty.
