Horizontal Radiators

Horizontal radiators are the go-to for reliable, even warmth. They sit neatly under windows to counter cooler air and keep living spaces comfortable day to day. To choose the right model, start with your BTU requirement so the output matches your room size. Single panels suit smaller rooms, while double panels boost heat where you need a bit more.

Measure width, height and projection so your designer horizontal radiator fits your space and furniture. Replacing an old unit? Check pipe centres to help reduce extra plumbing. Low-level options work well under bay windows or long runs of glazing, while compact lengths are ideal for utility rooms, hallways and snug layouts.

From flat panels to oval tubes and classic horizontal column designs, there’s a style to suit every interior. Keep it clean with white, go modern with anthracite or black, or choose a raw metal finish for character. Some ranges also include electric models if you’re not on central heating. Finish the look with co-ordinated valves and accessories for a polished result.

Not sure where to start? These quick guides will help you choose the right horizontal radiator.

 

What are horizontal radiators?

They’re the classic, under-window style used in most homes. They counter cooler air coming from glazing and distribute warmth evenly across the room.

 

Why choose a horizontal radiator?

Horizontal radiators offer consistent, everyday heat and are easy to position along longer walls. With plenty of widths, heights and finishes available, it’s simple to match both performance and style.

 

Are horizontal radiators as efficient as vertical ones?

Yes, horizontal radiators can be just as efficient as vertical radiators, as long as the BTU output is correctly matched to your room size. The choice usually comes down to layout, wall space and style. If you’re unsure, try our  How to Calculate BTU guide to find the right output for your space.

 

What material should I choose?

Aluminium heats up quickly and is lightweight, making alumium radiators ideal for fast warmth. Steel offers steady, reliable heat and a broader choice of designs. Match the material you prefer, then size the BTU correctly for comfort.

 

What size do I need?

Start with the BTU requirement for your room. Then select a height and width that fits your wall space. Double panel options offer more heat where needed.

 

Can I customise my radiator?

Yes, many of our horizontal radiators are fully configurable. You can choose the orientation, colour, height and width, and your BTU and price update instantly. This makes it simple to find a radiator that fits both your layout and heat requirement.

 

Can I replace a vertical radiator with a horizontal one?

Yes, but the pipe centres may differ, so pipework might need adjusting. Choosing a similar or higher BTU ensures the room stays warm.

 

Do I need new valves?

Often, yes. Match valve orientation to your pipework:

Choose a finish that complements your radiator.
