Return to page 1 of Horizontal Radiators

Horizontal radiators are essentially the norm when it comes to central heating systems. And for good reason, they're generally what your home already has fitted so replacing a radiator is far easier if it's done like for like. Although being the norm doesn't mean they have to look dull because our trendy collection shows you exactly what you could have. It shows you exactly what a simple upgrade could do for your home.

How do I choose the right size and heat output for my room?

Work from your room size and desired warmth, then match a radiator with the appropriate BTU band shown here (1,000–1,999 BTU for small bedrooms, 2,000–3,999 BTU for medium rooms and 4,000+ BTU for large living areas). Many horizontal radiators come in common heights of 300–700mm and widths from about 355mm up to 2,500mm, so you can increase output either by selecting a longer width or a taller model (600mm high is very common). You can also raise heat by choosing a double or triple panel configuration rather than a single panel. a 600 x 1,440mm double flat panel gives significantly more output than a single panel of the same footprint.

What’s the practical difference between column, panel and designer horizontal radiators?

Column radiators (like the Park Lane Colosseum) have a traditional, sculpted look and often come in double or triple bar versions that give strong heat and visual presence; they suit period homes or feature walls. Panel radiators, including flat-panel designer types such as the DuraTherm flat panels, give a contemporary, low-profile finish with shorter projection and are ideal for modern kitchens and living rooms. Designer or oval-tube styles merge form and function, offering distinctive shapes and finishes while still delivering good output, useful if you want the radiator as a visible design element.

How does single, double or triple panel configuration affect performance and projection?

A single panel usually has one convector fin and the shallowest projection, so it's best for smaller rooms or tight spaces. Double panels add a second parallel panel (often with one or two convector fins) to give noticeably higher output for medium to large rooms. Triple or six-panel radiators stack more panels and fins to maximise heat but have the largest projection from the wall; choose these when you need the highest BTU, in a large open-plan living area.

Are there many colour and finish options, and which should I pick for different rooms?

Yes, white is the most common finish, but anthracite and black are also widely available for contemporary schemes, with smaller runs in chrome, bronze, bare metal and polished aluminium for industrial or period looks. Pick white if you want a subtle, versatile radiator; choose anthracite or black to create contrast in a modern kitchen or living room; select metallic finishes for an industrial or high-end traditional bathroom. an anthracite double flat panel can really lift a grey kitchen, while a white 600 x 910mm panel blends quietly under a window.

When should I choose a horizontal electric radiator instead of a central-heating model?

Opt for a horizontal electric radiator when you don't have central heating in the room, when you need independent or seasonal heating (such as a conservatory or garage), or when a retrofit without pipework is preferable. Electric units are simple to install electrically and let you heat the space on demand, though they may cost more to run than a gas-fed central system. If you want a visible, modern radiator that's independent of your boiler, look at the horizontal electric options in the designer and panel ranges.
