Aqualisa iSystem Smart Shower - For Gravity Fed / Pumped Systems

Yes, the iSystem range is specifically designed for gravity‑fed and pumped systems, so it will suit a bathroom fed from a loft cistern or one that uses a shower pump. If your home already has a pump fitted, the pumped variant (for example the Exposed Smart Digital Shower, Gravity Pumped ISD.A2.EV.23) will give a noticeably fuller flow than an unboosted gravity feed. If you have a high‑pressure mains system such as a combi boiler, this gravity/pumped model is not the usual choice.

Thermostatic control holds the outlet temperature steady even when your system pressure changes, so sudden cold or hot blasts are much less likely. That makes showers more comfortable and safer for children or older users, flushing a toilet while someone is showering should not cause a temperature spike. It also lets you set a preferred temperature and rely on that setting every time.

"Smart digital" indicates electronic, precise control of temperature and flow, rather than purely mechanical knobs, so you get fine adjustment and repeatable settings. "Exposed" means the valve and controls sit on the surface of the wall, giving a clean, contemporary appearance and easy access for use and maintenance. The overall aesthetic is described as stylish, so this suits modern bathroom schemes.

The iSystem range supports pumped configurations, so adding or using an existing shower pump with a gravity feed will significantly improve spray and shower feel. Without a pump, a gravity feed can deliver a usable shower but the flow will be gentler; fitting a pump transforms that into a stronger, more satisfying experience. Many customers with loft cisterns choose the pumped version to get a shower closer to mains‑style performance.

The category highlights stylish aesthetics but currently shows one result: the Aqualisa iSystem Exposed Smart Digital Shower (Gravity Pumped ISD.A2.EV.23), so choices may be limited in this listing. That model gives you the smart, thermostatic benefits in an exposed configuration that suits contemporary bathrooms. If you want different finishes or concealed options, you can compare other Aqualisa iSystem models elsewhere in the broader range.
