Looking for a slim, space-saving radiator that still delivers reliable warmth? Our Type 11 radiators (single panel, single convector — also known as K1) are the slimmest convector radiators available, projecting the least from the wall for a clean, minimalist finish that suits even the most compact rooms.

What is a Type 11 radiator?

A Type 11 radiator has one front panel backed by a single layer of convector fins. Hot water heats the panel, the panel heats the fins, and the fins rapidly warm the air circulating through the room. With the smallest surface area of the convector range, a Type 11 offers a lower, efficient heat output — ideal where a larger radiator would simply overheat the space and waste energy.

Where Type 11 radiators work best

Small bathrooms and en-suites where wall space is tight
Cloakrooms, WCs and hallways that need gentle, efficient heat
Any room where a slim profile and minimal projection from the wall matter most

Quality you can trust

Our Type 11 collection features the trusted Kartell K-RAD range, known for excellent heat distribution, robust construction and a sleek, contemporary design that fits seamlessly into a modern bathroom. Available in a wide choice of widths and heights to suit your wall and heat requirement.

Not sure which type you need?

If you need more warmth than a Type 11 can offer, step up to a Type 21 radiator (double panel, single convector) for a stronger balance of output and slim depth, or a Type 22 radiator (double panel, double convector) for maximum heat in larger or harder-to-heat rooms. As a rule of thumb: small room → Type 11, average room → Type 21, large room → Type 22.
