Double Panels With a Single Convector

The K Rad Kompact combines two water-filled panels with one row of convector fins between them. Attached to one panel, the fins increase the surface area available to transfer warmth into the room, providing more heat than a comparable panel-only design.

Its 600 x 500mm size offers a compact option for your heating layout. When choosing panel radiators, match the model’s rated output to your room’s heating requirements.

K Rad Kompact Type 21 600 x 500mm Radiator - Double Panel Single Convector


A Neatly Finished Design

Factory-fitted side panels and a top grille cover the internal components while allowing warm air to circulate. This gives the radiator a tidy appearance that coordinates easily with different room styles.

For anyone comparing double panel plus radiators - type 21 (one internal convector), the Kompact offers a practical balance between heat transfer and radiator depth.

Mounting Accessories Supplied

The included heavy-duty L-shaped brackets attach to the wall, with the radiator hanging from holders pre-fitted to its back. An air vent, blanking plugs, screws, and screw caps are also supplied to help complete installation.

Standard G½-inch connection threads make it straightforward to connect suitable radiator valves. BS EN 442 conformity and a 10-year manufacturing warranty provide added reassurance.

    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.
