The Kartell K-Rad Kompact S316K is a Type 11 single panel, single convector radiator, 300 × 1600 mm, giving 837 W (2855 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. Nett weight is 13.76 kg and it holds 2.72 litres of system water.

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 300 mm high it tucks under low sills and full-height glazing.
Typical job
A room needing roughly 837 W on a 70 °C mean water temperature, or 1072 W where the system runs at 80 °C. Straight swap for a tired 300 × 1600 single panel of the same size.
Works with / replaces
Pipe centres are 245 mm with a wall-to-centre of 40 or 55 mm, so it lines up with most existing 300 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 837 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 431 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.
