style=\"padding:14px 16px;background:#f9fefe;\"\u003e\n      A gas or oil boiler delivers primary flow temperatures of 60–80 °C, giving a large temperature difference (delta-T) across the coil — so even a small coil surface area can transfer sufficient heat quickly. An air source heat pump typically delivers flow at \u003cstrong\u003e35–55 °C\u003c\/strong\u003e, dramatically reducing the available delta-T. To maintain the same heat transfer rate with a lower temperature difference, the coil surface area must be \u003cstrong\u003esubstantially larger\u003c\/strong\u003e. The Tempest HP's 3 m² coil on the 200–500 L models is purpose-designed for this application and is why this cylinder should not be substituted with a standard boiler cylinder on heat pump installations.\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #c8e6e3;border-radius:6px;margin-bottom:10px;\"\u003e\n    \u003csummary style=\"background:#008377CF;color:#fff;padding:12px 16px;border-radius:5px;cursor:pointer;font-weight:600;list-style:none;\"\u003eWhat clearance do I need around a horizontal cylinder in a loft?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;background:#f9fefe;\"\u003e\n      The cylinder diameter sits at \u003cstrong\u003e554 mm (170–300 L) or 660 mm (400–500 L)\u003c\/strong\u003e, and sits on cradles that bring the overall height to \u003cstrong\u003e654 mm or 760 mm\u003c\/strong\u003e respectively — measured from floor to top. As well as this height, allow a minimum service clearance on each side, typically \u003cstrong\u003e300 mm\u003c\/strong\u003e at each end for pipework connections and future servicing access, and \u003cstrong\u003e200 mm\u003c\/strong\u003e top clearance for the immersion heater removal path (check the installation manual for the specific size).

However, Telford offers a \u003cstrong\u003etwin-coil variant\u003c\/strong\u003e that can connect both a heat pump and a gas or oil boiler to independent coils. This is the recommended configuration for \u003cstrong\u003ehybrid heat pump installations\u003c\/strong\u003e where a boiler provides peak load or back-up.
