Ideal 175551 Expansion Vessel 8 Litre & 175413 PRV – Refurbished

A complete pressure management solution for your Ideal boiler — the Ideal 175551 Expansion Vessel (8 Litre) paired with the 175413 Pressure Relief Valve (PRV) work together to keep your heating system operating safely and efficiently. As water heats and expands within your sealed circuit, the expansion vessel absorbs the resulting pressure increase, while the PRV acts as the final safeguard — releasing any dangerous excess pressure before it can cause serious damage to your boiler's internal components.

Sold together as a matched kit, these two genuine Ideal parts restore complete pressure control to your system, making this an ideal choice for both routine maintenance and targeted fault repairs.

• Quality ensured by our experienced engineers
• Refurbished Ideal 175551 Expansion Vessel Kit 8L with Pressure Relief Valve
• Comes with 12 month warranty
