How do I work out the right size radiator for my room?

Check the BTU output shown for each model and match it to the heat requirement of your room; the collection offers outputs from under 1,000 BTU up to 25,000 BTU (Delta 50). Use the physical dimensions too, with heights available include 600, 1200, 1600 and 1800 mm and widths range from about 240 mm up to 1800 mm, so you can fit a radiator under a window or on a long wall. If you need a powerful unit for a medium living room you might choose a double-panel horizontal like the DuraTherm 600 x 1440 mm; for a narrow hallway a tall 1800 x 360 mm vertical will give good output with a small footprint.

Should I choose a horizontal or a vertical black double radiator?

Horizontal radiators suit runs under windows or long low walls, while vertical radiators free up skirting space and are ideal where width is limited. We have a wide range of both vertical and horizontal options in our range, so you can match placement and style that suits your needs. If you have a small bathroom or narrow hall, a vertical DuraTherm 1800 x 530 mm gives strong heat without taking wall length; for a living room under the sill, a horizontal 600 x 1440 mm is a common choice.

What difference does double panel make compared with single or triple panels?

Double-panel radiators have two parallel panels (often with convector fins) so they give higher heat output than single panels yet remain slimmer than triples; that's why most of our collection on the website are double units. Single panels have the shallowest projection and suit small rooms, while triple panels maximise output for very large or poorly insulated spaces but project further from the wall. If you want to heat a medium-to-large room efficiently without a very deep radiator, a double panel is usually the sensible balance.

Is aluminium or mild steel better for a black double radiator?

Both work well but behave differently: aluminium models heat up and respond faster and are lighter, so they're good where quick temperature change is wanted; mild steel is robust, widely available in flat and column profiles and tends to retain heat longer. For a modern, responsive bathroom radiator you might opt for an aluminium vertical; for a traditional sitting room look and steady heat, a mild-steel column like the Park Lane Colosseum suits well.

How do I pick a style that matches my room without losing performance?

The range includes modern flat or oval panels and traditional column/colosseum designs, all in a striking black finish, you can have style and heat output together. Modern flat-panel DuraTherm radiators deliver a sleek look with efficient double-panel output; Park Lane's double bar column radiators give a period appearance while still heating medium-to-large rooms effectively. Choose a DuraTherm horizontal double flat panel 600 x 1060 mm for a minimalist lounge, or a Park Lane 600 x 1010 mm double column for a period living room that needs style and substance.
