What’s Included:
K Rad Kompact Type 21 750 x 700mm Radiator - Double Panel Single Convector
Compatible with:
Standard UK radiator fittings (comes with G1/2-inch connections)
This Type 21 Panel Radiator combines two water-filled panels with a single row of convector fins. The increased surface area provides stronger heat output than a single-panel radiator while maintaining a shallower projection than a Type 22 model.
This balance of performance and size makes it a practical option for bedrooms and other small or medium-sized rooms.
Double-Panel Construction
Two heating panels provide a larger surface area for transferring warmth into the room. This increases the radiator’s output without requiring a double row of convector fins.
Single Convector
A single set of fins sits between the panels and warms the air as it circulates through the radiator. The result is improved heat output compared with a plain panel design.
Balanced Projection and Output
A Type 21 radiator projects further from the wall than a Type 11 but remains slimmer than a Type 22. It is a useful middle ground where stronger output is needed but wall space remains important.
Always select the radiator size using a proper room heat-loss calculation.
Pre-Fitted Grille and Side Panels
The factory-fitted top grille and side panels conceal the internal components and create a neat finish without restricting the circulation of warm air.
Wall Brackets Included
Heavy-duty L-shaped brackets attach directly to a suitable wall. The radiator then hangs securely using the mounting points fitted to its rear.
Wall construction varies, so ensure that the selected fixings are suitable for the installation surface and the filled weight of the radiator.
Standard UK Connections
G½-inch threaded connections provide compatibility with commonly used UK central-heating systems and radiator valves.
BS EN 442 Conformity
The radiator conforms to BS EN 442, the recognised standard covering the testing and declared performance of central-heating radiators.
10-Year Warranty
A 10-year guarantee covers qualifying manufacturing defects, subject to correct installation, maintenance and the manufacturer’s terms.
Installation Information
Check the radiator dimensions, pipe centres and required heat output before ordering. Radiator valves may need to be purchased separately unless the selected listing states otherwise.
Installation should be completed by a competent heating professional. The system must be flushed, filled with a suitable corrosion inhibitor and commissioned in accordance with the manufacturer’s instructions.
Explore Type 21 panel radiators at Plumbworld and achieve strong, dependable heating without the deeper profile of a double-convector model.

I needed to replace all my radiators as they were over 35 years old. These look better and seem to heat up quicker. Great buy.

Bought this Rad to replace an old single panel Rad.
Finish’s off a newly decorated hallway nicely and giving off a lot of heat - which is probably overkill seeing as it is the same length as the old one.
Only problem I faced was not ensuring the tails were super tight before fitting to the wall - one end started to loosen as I tightened the pipework to it (tightening in the opposite direction) - user error!

I went for this brand as it had a higher heat output than the Screwfix/Toolstation/B&Q equivalent. It is well made with a good finish. All the normal fittings included. I would buy again.
