Single Panel Radiators

The slimmest of the three sizes is the Type 11, which has a front panel and one set of fins behind. Sometimes called a K1 type, this design gives out the lowest heat, but is also much thinner than type 21 and type 22 radiators, so is perfectly suited to rooms where space is a premium. They’re also useful when you don’t need a high heat output – such as in a cloakroom or ensuite bathroom, or as a secondary radiator in a large room.
