Type 11

A type 11 panel radiator has one water panel with one row of convector fins at the back. It is the slimmest panel radiator, so it suits places where space in front of the wall is limited: hallways, small bedrooms, kitchens and spots under low windows.

For the same length it gives less heat than types 22 and 33. If a room needs more output and a longer radiator will not fit, look at the type 22 range. Codes show type, height and length in millimetres, and the kcal output is listed for each model.
