Ceramic radiators will always reach higher temperatures than lightweight dry thermal alternatives. This is because they’ve been fitted with dense ceramic heating blocks that retain heat as the radiator produces it. This is great for efficiency and reducing running costs but does mean the radiator surface can be noticeably hotter to the touch than non-ceramic alternatives.
The iQ Ceramic is temperature limited to 71°C, measured at the top of the radiator, but surfaces directly opposite the heating element can reach higher temperatures.
