produces a slightly greater volume of combustion gases, which increases resistance in the flue system. Ariston's published maximum vertical run for the E-Combi ONE on Ø60\/100 is \u003cstrong\u003e8 metres at 24 kW and 7 metres at 30 kW\u003c\/strong\u003e. Each 90° elbow (3318075) deducts from these totals — refer to the installation manual for the specific deduction per fitting. If the installation requires more than 7 metres, upgrading to the \u003cstrong\u003eØ80\/125 coaxial system supports up to 24 metres\u003c\/strong\u003e on the 30 kW model, though this requires a different starter and larger roof penetration.\u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"border:1px solid #ddd;border-top:none;padding:0;\"\u003e\n    \u003csummary style=\"padding:14px 16px;cursor:pointer;font-weight:600;background:#f9f9f9;\"\u003eShould I choose the 24 kW or 30 kW for my lodge or static caravan?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;border-top:1px solid #eee;\"\u003eThe key differentiator is \u003cstrong\u003ehot water demand\u003c\/strong\u003e.
