Potterton Promax Combi 24 ERP Expansion Vessel 8 Litre – Brand New | MPN 5114691

Behind every smoothly running heating system is a component working quietly to keep pressure and temperature in balance — and the Potterton Promax Combi 24 ERP Expansion Vessel (MPN 5114691) does exactly that. As water heats up and expands within your sealed central heating circuit, this vessel absorbs the excess volume, regulating system pressure and preventing the kind of strain that leads to leaks, faults, and reduced efficiency over time.

With an 8-litre capacity, it provides ample room for expansion, keeping your system running smoothly and efficiently across every heating cycle. Compatible with most Baxi boilers, it's designed for straightforward, hassle-free installation as a reliable, precise fit
