The horizontal orientation makes it ideal where headroom is limited — fitting neatly in a loft, cupboard, or plant room on its side. Accumulators store mains water under pressure so you draw instantly at full mains pressure the moment you open a tap or shower, delivering noticeably stronger, more consistent flow even during peak demand periods.\u003c\/p\u003e\n\u003cp style=\"font-size: clamp(13px,1.1vw,15px); color: #3c3f47; line-height: 1.7; margin: 0 0 12px 0;\"\u003eThe AWBH-250LH operates on a \u003cstrong style=\"color: #0e1117;\"\u003e60% usable volume ratio\u003c\/strong\u003e — delivering approximately \u003cstrong style=\"color: #0e1117;\"\u003e150 litres of high-pressure water\u003c\/strong\u003e before returning to normal mains flow. At a typical shower flow of 12 l\/min, 150L supports two simultaneous showers for approximately 6 minutes before returning to normal mains flow.
