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 2551 W on a 70 C mean water temperature, or 3268 W where the system runs at 80 C. Straight swap for a tired 500 1600 panel of the same size. Works with / replaces Pipe centres are 445 mm with a wall-to-centre of 82.5 or 97.5 mm, so it lines up with most existing 500 mm-high panels. Case depth is 105 mm against 70 mm for a Type 21 and 160 mm for a Type 33. When not to choose this The 2551 W figure is at T50. Run a heat pump at low flow temperatures and it falls hard Kartells own correction factor at T30 is 0.515, so you would get about 1314 W from this radiator. Size at the T you will actually run, and step up to a Type 33 where the size allows, or split the load across two radiators.

Key specifications

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.
