| 1 | 600 × 1000 mm Type 22 panel radiator | Average living rooms | 600 mm high × 1000 mm wide | About 1,700–1,900 W | Steel panel with two panels and two convector layers | Compatible with standard thermostatic radiator valves and 15 mm pipework | Balanced heat output, depth and cost |
| 2 | 600 × 800 mm Type 22 panel radiator | Medium bedrooms | 600 mm high × 800 mm wide | About 1,350–1,550 W | Pressed steel panel with integrated convectors | Suitable for angled, straight or remote-sensing TRVs when correctly installed | Good output where wall space is limited |
| 3 | 600 × 1200 mm Type 22 panel radiator | Large living rooms and open-plan areas | 600 mm high × 1200 mm wide | About 2,050–2,300 W | Double steel panel with double convection fins | Standard two-pipe central-heating systems with compatible valve connections | Higher output without increasing radiator depth |
| 4 | 500 × 600 mm Type 22 panel radiator | Small bedrooms and home offices | 500 mm high × 600 mm wide | About 850–1,050 W | Compact steel panel with two convection layers | Works with standard Thermostatic Valves, subject to connection layout | Space-efficient option for lower heat requirements |
| 5 | 600 × 1000 mm Type 21 panel radiator | Rooms needing a slimmer radiator | 600 mm high × 1000 mm wide | About 1,350–1,550 W | Two steel panels with one convection layer | Compatible with conventional and low-temperature heating circuits | Less projection from the wall than a Type 22 radiator |
| 6 | 600 × 1000 mm Type 11 panel radiator | Narrow hallways and compact rooms | 600 mm high × 1000 mm wide | About 950–1,150 W | Single steel panel with one convection layer | Suitable for standard TRVs with correctly matched tails and adapters | Shallow profile where floor and wall clearance matter |
| 7 | 600 × 1400 mm Type 22 panel radiator | Cold external-wall rooms | 600 mm high × 1400 mm wide | About 2,400–2,700 W | Double steel panel with two convection layers | Compatible with manual or thermostatic control valves | High output for rooms with greater heat loss |
| 8 | 600 × 1000 mm low-temperature Type 22 radiator | Heat-pump systems | 600 mm high × 1000 mm wide | Output must be checked at the system’s lower flow temperature | Large surface-area steel panel construction | Suitable for TRVs rated for the selected heating system | Designed for efficient operation at reduced flow temperatures |
| 9 | 600 × 500 mm compact vertical panel radiator | Kitchens and narrow wall sections | Approximately 600 mm high × 500 mm wide | About 700–900 W | Compact steel panel with convector fins | Requires connection positions and TRV orientation to be checked carefully | Uses limited horizontal wall space |
| 10 | 600 × 1200 mm aluminium sectional radiator | Fast-response rooms and modern heating controls | Approx. 600 mm high × 1200 mm wide | Varies by section count and operating temperature | Lightweight aluminium sections | Usually compatible with standard TRVs using the correct thread and adapters | Low water content allows rapid response to temperature changes |
