As a system boiler it heats the central heating circuit directly and works alongside a \u003cstrong\u003eseparate hot water cylinder\u003c\/strong\u003e — delivering higher simultaneous hot water flow rates than a combi and eliminating the need for a cold water tank in the loft. The RinNova Adaptive system boiler shares the same compact \u003cstrong\u003e700 × 400 × 300 mm\u003c\/strong\u003e casing as the combi S-model but with a \u003cstrong\u003eCH-only hydraulic circuit\u003c\/strong\u003e: there is no diverter valve, no internal plate heat exchanger, and no DHW flowmeter. An optional \u003cstrong\u003eexternal cylinder sensor (E07)\u003c\/strong\u003e connects to the PCB to allow the boiler to monitor and control cylinder temperature. The boiler features \u003cstrong\u003eAdaptive Gas Technology\u003c\/strong\u003e for automatic combustion optimisation, a \u003cstrong\u003epatented mono-spiral stainless steel heat exchanger\u003c\/strong\u003e, a \u003cstrong\u003eplastic-free brass hydraulic unit\u003c\/strong\u003e, an \u003cstrong\u003eErP-rated modulating circulating pump\u003c\/strong\u003e, and a \u003cstrong\u003e7-litre integral expansion vessel\u003c\/strong\u003e. It carries an \u003cstrong\u003eErP Energy Class A\u003c\/strong\u003e rating — upgradable to \u003cstrong\u003eA+\u003c\/strong\u003e with the optional iControl weather-compensation system — and is backed by \u003cstrong\u003eup to 8 years warranty\u003c\/strong\u003e (subject to Biasi T\u0026amp;Cs).
