Flatty White Vertical Column Panel Radiator – Single & Double

Maximise your heating potential with this stylish white vertical column panel radiator that delivers exceptional style and dependable warmth. The commanding vertical layout makes a feature of your heating while freeing up valuable floor area. The smooth classic white finish brings a clean, bright look to living rooms, hallways, kitchens, or bathrooms. Choose a Single Panel for a slimmer projection or a Double Panel when you need maximum BTU output in larger or cooler rooms.

Why this model?

Efficient heat, faster comfort: High surface area columns promote quick, even heat distribution.
Space-Saving Design: The tall, narrow footprint makes the most of small wall sections beside doors or windows, drawing the eye upwards.
Built for everyday life: The durable, smooth white finish is easy to clean and maintains a fresh, bright appearance.

Single vs Double Panel

Single Panel: A slimmer profile; ideal for compact rooms or when projection from the wall is a concern.
Double Panel: Greater surface area provides a higher BTU output for open-plan living, rooms with high ceilings, or north-facing spaces.

Sizing & BTU Guidance

Always size your radiator by BTU requirement rather than physical dimensions. Use our BTU Calculator to estimate the ΔT50 BTU output needed based on room dimensions, insulation, and glazing. You can meet the total BTU requirement with one larger radiator or by combining multiple radiators in the same room.

What’s Included

Wall brackets & fixings
Blanking plug & bleed valve
Installation guide

Valves not included. Pair with angled or straight valves to suit your pipework; a thermostatic (TRV) set is recommended for finer temperature control.

Why vertical

Height instead of wall

Stood up, a column radiator puts the same heat into a room as a long horizontal one off a fraction of the wall. That is the point of the range: it goes where a radiator was never going to fit — beside a door, under a window, in the gap between two units.

2885–8001: BTU at ΔT50, across the range
16: sizes, at 1600 and 1800 mm
79 mm: projection on a single panel

Build

Steel, finished in white

Low-carbon steel under a white powder coat, with flat panels rather than round tubes — the face wipes down in one pass. Outputs are measured to British Standard BS EN 442, and the radiator carries a five-year guarantee.

Before you order

Valves are the one thing to add

Brackets, fixings, blanking plug and bleed valve are in the box; valves are not. Which pair depends on where your pipes come into the room, and a thermostatic set is worth it here — a vertical panel this size can overheat a room left on full.

See the valve range

Which valve fits your pipework?

All three hold this room at the temperature you set on the dial, independently of the rest of the house. What changes between them is how your pipes come into the room.

Valve	Choose it when	Price	Product page
Straight TRV, whiteFloor pipes	Pipes come up out of the floor under the radiator inlets and carry straight on into the valve.	£36.00	View the straight trv, white valve
Angled TRV, whiteWall pipes	Pipes leave the wall horizontally. The valve turns them 90° into the radiator for you.	£36.00	View the angled trv, white valve
Corner TRV, whiteWall pipes	Also wall pipes, but tucked in tighter — the body sits close to the wall and stays out of the way.	£36.00	View the corner trv, white valve
