Vaillant Turbomax Expansion Vessel 8 Litre – MPN 181045

Every time your heating system fires up, water expands as it heats — and without the right component in place to manage that expansion, pressure builds to levels that can damage your boiler's most critical parts. The Vaillant Turbomax Expansion Vessel (MPN 181045) is engineered to handle exactly that. At its core sits a robust rubber diaphragm that compresses as water volume increases, absorbing the excess pressure and keeping your system operating safely within its intended parameters throughout every heating cycle.

With an 8-litre capacity and designed specifically for Vaillant Turbomax boilers, this vessel fits as a precise like-for-like replacement — straightforward to install and immediately effective, making it a practical choice for both professional engineers and confident DIY enthusiasts.
