FAQs

What is a Type 11 radiator and how does it work?

A Type 11 radiator, also called a K1 radiator, is a single-panel convector radiator made from a flat metal panel, usually steel, with one set of convection fins attached behind to increase the surface area for heat emission. Hot water from the central heating system flows through the panel, warming it and encouraging warm air circulation through the fins. This design produces gentle, efficient heat that is well-suited to smaller rooms, and while its heat output is lower than double-panel models, it can still provide substantial warmth thanks to the added fins.

Where are Type 11 radiators most suitable?

Single-panel radiators are slim, protrude less from the wall, and are a practical choice for narrow spaces such as hallways, bathrooms, small bedrooms, or conservatories, where their gentle heat output matches the lower heating requirements. With a typical output of around 1-1.5 kW (3400-5200 BTU), Type 11 radiators are best suited to rooms with minimal heat loss, while larger spaces generally require higher-output options such as Type 22 or Type 33 radiators with multiple panels and fins.

Are Type 11 radiators energy efficient?

Type 11 radiators are considered energy efficient because their convection fins increase the surface area for heat transfer, allowing them to emit more heat than a plain single-panel unit while still using less energy than larger models. They require a smaller volume of water to operate, which means they heat up quickly and cool down faster, making them ideal for rooms that are used intermittently or do not require constant high heat. While they may not retain warmth as effectively as double- or triple-panel radiators in larger spaces, they deliver a strong balance of quick response, lower water demand, and efficient heat distribution in smaller rooms.

How much clearance does a Type 11 radiator need for proper airflow?

It is recommended to leave around 100 mm of space on each side of a radiator, 150 mm above, and at least 150 mm below from the floor to allow proper airflow. These clearances help the radiator convect heat efficiently and prevent nearby furniture or obstacles from blocking heat circulation.

Can Type 11 radiators be used with modern heating controls?

Yes, Type 11 radiators can be used with modern heating controls. They are compatible with thermostatic radiator valves (TRVs), which allow precise temperature regulation and improve energy efficiency by controlling how much heat the radiator gives off. Like other panel radiators, they operate with central heating systems that supply hot water and can be connected to standard boilers, combi boilers, or renewable systems such as heat pumps, provided the system meets the room’s heating needs.
