Applications & suitability

Where it goes

Wall-hung on a sealed or open-vented wet heating system, fixed no lower than 100 mm off the finished floor. At 400 mm high it suits a wall where vertical space is tight.

Typical job

A room needing roughly 1816 W on a 70 °C mean water temperature, or 2299 W where the system runs at 80 °C. The pick where a slimmer panel the same width cannot reach the load.

Works with / replaces

Pipe centres are 345 mm with a wall-to-centre of 82.5 or 97.5 mm, so it lines up with most existing 400 mm-high panels. Case depth is 160 mm against 105 mm for a Type 22 — check the projection suits the room.

When not to choose this

The 1816 W figure is at ΔT50. Run a heat pump at low flow temperatures and it falls hard — Kartell’s own correction factor at ΔT30 is 0.515, so you would get about 935 W from this radiator. This is already the deepest, highest-output panel in the range at this size — if it still falls short, go wider or split the load across two radiators.

Installation & compatibility

Fix no lower than 100 mm from the finished floor. Allow 35 mm from the wall to pipe centre for a manual valve, or 45 mm for a TRV. Kartell requires the system to be cleansed and dosed with inhibitor to BS 7593:2019 — skipping it invalidates the guarantee, which covers product replacement only. Leave the protective packaging on until the radiator is fixed and the tappings are cut.
