Type 21 (Double Panel, Single Convector) – Slightly deeper than Type 11 with increased heat output. Second panel plus one convector fin for better performance; great for medium rooms.

Type 22 (Double Panel, Double Convector) – Highest output; two panels and two sets of convector fins for fast, consistent warmth in larger rooms.

Important – Water Treatment / Corrosion Inhibitor

To keep your radiator working efficiently and to maintain your guarantee, ensure systems are cleaned and treated before installation: flush with a cleaning agent and add a central heating inhibitor.

This is especially important on older/existing systems to prevent corrosion and protect long-term performance. Please note: not following these steps may affect the radiator’s guarantee.
