79mm Profile
Why choose the Aspen 600 x 540mm Horizontal Double White?
1

2,948 BTU — Double the Output of the Single Panel

The double panel ASP60-55DW delivers nearly double the heat of the single panel ASP60-55SW from the same 540mm wall width. Ideal for bathrooms and en-suites where more heat is needed in a compact space.

2

540mm Wide — Compact Horizontal Format

At just 540mm wide this fits neatly in bathrooms, kitchens and alcoves where a longer radiator won’t fit. 540mm tapping centres means it replaces most standard 540mm wide radiators directly.

3

Double Panel — 79mm Depth

The 79mm double panel depth is only 24mm more than the single panel at 55mm. In most bathrooms and kitchens this additional projection is unnoticeable, but the extra heat output is substantial.

4

Gloss White — Classic Bathroom Finish

Gloss white suits both modern and traditional bathrooms and kitchens. Matches standard UK radiator valves, towel rail fittings and bathroom furniture for a clean, seamless look.

5

Oval Tube Designer Construction

Greater surface area than round tubes for more efficient heat transfer per millimetre of width. The oval tube design gives a premium aesthetic over standard flat panel alternatives.

6

5 Year Kartell UK Guarantee

Weighing 12.38kg. All wall brackets, fixing screws, wall plugs, air vent and blanking plug included. Pressure tested to 7.8 bar. Registered directly with Kartell UK.

Which radiator valves do I need?

Valves are not included and must be purchased separately. For this gloss white radiator we recommend White TRV valves for a seamless match. Select your pipework type below.

Angled White Radiator Valves

When to use: Pipework rises vertically from the floor to the side connections. The most common UK installation type.

Straight White Radiator Valves

When to use: Pipework rises from the floor and connects directly in a straight vertical line to the bottom tappings.

Corner White Radiator Valves

When to use: Pipework comes horizontally out of the wall to the side connections of the radiator.
