K Rad Kompact Type 21 400 x 1000mm Radiator - Double Panel Single Convector

Efficient Type 21 construction

A Type 21 radiator combines two heating panels with one convector. This provides a higher output than a single-panel design without the additional depth of a double-convector Type 22 radiator.

Pre-fitted side panels and top grille

Factory-fitted covers conceal the internal convector and give the radiator a clean, finished appearance. The top grille still allows warm air to circulate freely into the room.

Wall-mounting brackets included

Heavy-duty L-shaped brackets are supplied alongside an air vent, blanking plug, screws and screw caps. Once the brackets have been securely fitted, the radiator hangs from the mounting points on its rear.

The installer must confirm that the supplied fixings are appropriate for the construction and condition of the wall.

Standard UK plumbing connections

G1/2-inch threaded connections provide compatibility with commonly used UK radiator valves and central-heating pipework.

Please note: Radiator valves are not stated as included and may need to be purchased separately.

BS EN 442 compliant

The radiator conforms to BS EN 442, the recognised European standard covering radiator testing and declared performance.

10-year warranty

This Type 21 radiator comes with a 10-year warranty against manufacturing defects. Terms and conditions apply.

Bring efficient warmth to your room with a Type 21 panel radiator from Plumbworld.

    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.
