Vertical radiators

A vertical radiator turns the problem of where to put the heating into a feature. By standing tall rather than wide, it frees up the wall space a horizontal radiator would eat, which is why it suits narrow walls, hallways and modern kitchens where every metre counts. It also looks striking, so it doubles as a design statement. The one number to keep an eye on is the heat output, since a slim, tall radiator needs checking against what the room requires.

Why go vertical?

Vertical radiators save wall space. They take up height instead of width, so they fit where a wide radiator will not: beside a door, on a slim section of wall, in a hallway or down the side of a kitchen run. That frees the rest of the wall for furniture, units or art. They also make a tall, deliberate feature, which is why so many designer radiators are vertical. For a room that is short on wall but not on height, vertical is the obvious answer.

Output and height

Because a vertical radiator is often slim, its heat output is the thing to check before you buy. A tall, narrow single-panel radiator can give out less heat than a wide one, so confirm the output (its BTU figure) matches what your room needs. If a slim model falls short, a taller, wider or double-panel version, or an aluminium one, gives more heat in the same upright form. Size on output first, then enjoy the space you have saved; do not assume a tall radiator automatically heats a big room.

Height also affects where the radiator can go. A tall vertical needs a clear run of wall from low down to high up, away from wall units, worktops and light switches, so measure the full height as well as the width of the gap. The payoff is that the heat rises up the room from a single slim source, which works well in rooms with high ceilings where a low, wide radiator can leave the upper space cooler.

Where vertical radiators suit

Vertical radiators come into their own wherever wall space is tight or you want a feature. Hallways and landings, where a wide radiator would block the run, are the classic case. Narrow walls between doors or windows suit them, as do modern kitchens where wall space is given over to units. In a living room, a tall designer vertical can be the focal point of the wall. About the only place to think twice is under a window, the traditional radiator spot, where a horizontal design usually fits better. Anywhere the wall is taller than it is wide, though, a vertical is likely to be the neater and more striking solution.

Many verticals are also designer radiators; for the choice between upright and across, see vertical vs horizontal radiators (linking when live).

Single or double panel?

If a slim vertical is short on heat, the usual answer is a double-panel version. A single-panel radiator has one heated face, which keeps it slim and discreet; a double-panel has two, so it gives out noticeably more heat from the same footprint at the cost of sticking out a little further from the wall. On a tall vertical that matters, because it is often how you get the output a room needs without making the radiator wider. So if the look you want comes up short on the BTU figure, check whether the same design is offered as a double panel before you compromise on the style or the size.

Vertical radiator FAQs

Do vertical radiators heat a room as well as horizontal ones?

They can, as long as the output matches the room. Heat output depends on the radiator's size and surface area, not whether it is tall or wide, so a vertical radiator with the right BTU figure heats just as well. Check the output rather than assuming, since slim models can give out less.

Why choose a vertical radiator?

To save wall space and make a feature. A vertical radiator takes up height instead of width, freeing wall for furniture and suiting narrow walls, hallways and kitchens, while looking striking. It is the practical choice where a wide radiator will not fit.

Where should I put a vertical radiator?

On a narrow or tall stretch of wall: beside a door, in a hallway, between windows, or as a feature in a living room or kitchen. The one spot they suit less is directly under a window, where a horizontal radiator usually fits the space better.

Are vertical radiators more expensive?

Often a little, because many are designer pieces, but not always. A plain vertical panel can be similar to a horizontal one; a sculptural designer vertical costs more for the styling. Compare on output and finish, not format alone.

Can a vertical radiator go under a window?

It can, but it is rarely the best use of one. Verticals are tall, so under a standard window they end up short and wide, which loses the space-saving advantage that makes them worth choosing. Under a window a horizontal radiator usually fits the space better; save the vertical for a tall, narrow wall where it can do what it does best.
