View full detailsWant more warmth than a slim single-panel radiator, without it projecting too far from the wall? Our Type 21 radiators (double panel, single convector — often labelled P+) are the versatile all-rounder of the convector range, striking the ideal balance between strong heat output and a neat, space-conscious depth.
A Type 21 radiator has two panels with a single layer of convector fins sandwiched between them. That second panel delivers noticeably more heat than a single-panel Type 11, while keeping the radiator slimmer than a twin-convector Type 22. The result is excellent, responsive warmth from a relatively compact footprint.
Our Type 21 collection features the trusted Kartell K-RAD range, engineered for robust, efficient heating with a contemporary finish that complements any bathroom. Choose from a broad selection of widths and heights to match your wall space and heat requirement.
Need a slimmer option for a smaller space? See our Type 11 radiators (single panel, single convector). Heating a larger or harder-to-warm room? A Type 22 radiator (double panel, double convector) offers the highest output. As a quick guide: small room → Type 11, average room → Type 21, large room → Type 22.
