This listing includes the boiler, the \u003cstrong\u003eCube RF wireless modulating room sensor and receiver\u003c\/strong\u003e, and the \u003cstrong\u003estandard horizontal coaxial flue kit (Ø60\/100)\u003c\/strong\u003e. The Cube RF is what qualifies the boiler for the A+ ErP rating and satisfies the Boiler Plus load-compensation requirement — nothing additional is needed for a compliant installation in most properties.\n    \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;\"\u003eWhat is the maximum horizontal flue run for the 35 kW model?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;border-top:1px solid #eee;\"\u003e\n      Using the standard \u003cstrong\u003eØ60\/100 coaxial system\u003c\/strong\u003e, the maximum flue run is \u003cstrong\u003e5 metres\u003c\/strong\u003e for the 35 kW version.

This reduces gas consumption by preventing the boiler from overshooting on mild days, complementing the Cube RF's indoor load-compensation.\n    \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;\"\u003eCan the Alteas ONE+ NET run on LPG without a conversion kit?\u003c\/summary\u003e\n    \u003cdiv style=\"padding:14px 16px;border-top:1px solid #eee;\"\u003e\n      Yes. The \u003cstrong\u003eCombustion Control System\u003c\/strong\u003e automatically detects the fuel type at commissioning and self-calibrates the air-to-gas ratio without any physical conversion kit.

The low-temperature range of \u003cstrong\u003e20–45°C flow temperature\u003c\/strong\u003e makes the Alteas ONE+ NET fully compatible with underfloor heating circuits. A blending valve is typically still recommended to protect the UFH manifold and limit surface temperatures.
