The Kartell K-Rad Kompact S530K is a Type 11 single panel, single convector radiator, 500 × 3000 mm, giving 2448 W (8351 BTU/h) at ΔT50. A single water-carrying panel with one bank of convector fins in a 56 mm case — the slimmest panel in the Kompact range, and the easiest to fit alongside pipework, furniture and door swings. At 3000 mm wide it is a long radiator — check the run of clear wall before ordering.

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 500 mm high it suits a wall where vertical space is tight.
Typical job
A room needing roughly 2448 W on a 70 °C mean water temperature, or 3136 W where the system runs at 80 °C. Straight swap for a tired 500 × 3000 single panel of the same size.
Works with / replaces
Pipe centres are 445 mm with a wall-to-centre of 40 or 55 mm, so it lines up with most existing 500 mm-high panels. Case depth is 56 mm against 70 mm for a Type 21 and 105 mm for a Type 22.
When not to choose this
The 2448 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 1261 W from this radiator. Size at the ΔT you will actually run, and step up to a Type 21 or Type 22 at the same size if the load needs it.

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.
