Why choose the Kartell K-Rad Aspen 1600 x 420mm Double White?
1

Thanks to the 14 double oval tubes, it comfortably heats a medium to large living space, bedroom, or kitchen dining area independently.

3

Classic White Gloss Finish

The bright white gloss powder coat is clean, highly durable, and blends seamlessly with modern minimalist or traditional decor.

4

5 Year Kartell UK Manufacturer Guarantee

6

Understanding Delta T60 and heat pump output

All radiator heat outputs are quoted at Delta T60 — the European standard for testing, which assumes a mean water temperature 60°C above room temperature. Most modern combi boilers operate at or near this standard.

Heat pump users: At Delta T50, multiply by 0.789 — giving approximately 4,595 BTU.

Which radiator valves do I need?

Valves are not included and must be purchased separately. Because this is a White radiator, we highly recommend White or Chrome TRV valves. Select your pipework configuration below.

Angled White Radiator Valves

When to use: Pipework rises vertically from the floor and connects to the side connections of the radiator.

Most popular choice — angled valves suit the majority of UK installations.

Straight White Radiator Valves

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

Corner White Radiator Valves

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