All six sizes share a 545 mm diameter; only the length varies. In a typical loft, 545 mm clearance is achievable even where a 1,600 mm+ vertical cylinder would not fit under the rafters. The removable cradles allow the bare cylinder to pass through a narrow access hatch and be reassembled in situ — not possible with a vertical unit.

The coil-in-coil smooth tube coil is designed to work with any air-to-water heat pump. At heat pump flow temperatures (45 – 55°C), recovery is slower than with a boiler (70 – 80°C primary). Size up by one step — for example, choose 250L instead of 210L for a 3 – 4 person household — when a heat pump is the sole primary heat source. The 3 kW immersion provides backup if the heat pump fails and can top up DHW overnight on a cheap tariff.\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border: 1px solid #cde3e1; border-radius: 8px; margin-bottom: 10px; overflow: hidden;\"\u003e\n\u003cdetails\u003e\n\u003csummary style=\"padding: 14px 18px; font-size: 15px; font-weight: bold; color: #005c54; cursor: pointer; list-style: none; display: flex; align-items: center; justify-content: space-between; background: #f5fbfa;\"\u003e\u003cspan\u003eDoes the complete safety kit come included?\u003c\/span\u003e\u003csvg width=\"18\" height=\"18\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"#008377\" stroke-width=\"2.5\"\u003e\u003cpolyline points=\"6 9 12 15 18 9\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/summary\u003e\n\u003cdiv style=\"padding: 14px 18px 16px; font-size: 15px; color: #444; line-height: 1.65; border-top: 1px solid #cde3e1; background: #fff;\"\u003eYes.

Shower performance is poor, and hot and cold water pressures are badly mismatched. An unvented cylinder operates hot water at the same pressure as the cold mains — typically 2 – 3.5 bar. This gives dramatically improved flow at showers and taps, truly balanced hot and cold for thermostatic mixer showers (no cold water pump needed), and eliminates the cold water storage tank.
