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 2464 W on a 70 C mean water temperature, or 3157 W where the system runs at 80 C. Straight swap for a tired 500 2000 panel of the same size. Works with / replaces Pipe centres are 445 mm with a wall-to-centre of 65 mm or 80 mm, so it lines up with most existing 500 mm-high panels. Case depth is 70 mm against 56 mm for a Type 11 and 105 mm for a Type 22. When not to choose this The 2464 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 1269 W from this radiator. Size at the T you will actually run, and step up to a Type 22 or 33 if the load needs it.
