Central Heating Radiators

Why your radiator really matters for your heating system

Your central heating radiators are the final step in converting boiler energy into warmth. Choosing the wrong one will inevitably lead to wasted energy or troublesome cold spots. And with the ever-increasing cost of living and high energy bills, you need units that deliver exactly what your system requires.

That’s why we prominently display the full BTU and wattage ratings, including the Delta T test conditions (usually Delta T50), on every single model. Knowing these figures ensures your radiator will function efficiently within your central heating system and won't unduly overwork the boiler.

Matching the right size: avoid surprises

Sizing errors are, hands down, the most frequent cause of installer confusion and fitting delays. Every single radiator in the listing clearly shows its pipe centres, height, width and depth in mm. Now, you can easily check it against your existing pipework.

Panel types and how they affect heat

Radiators come in different panel formats. A typical heating unit might be a “single panel” (Type 10 or 11) or a “double panel” (Type 21 or 22). Simply put, double panels generally pack a significantly higher heat output for their size, great for a large, chilly lounge.

Material matters: quick heat or lasting warmth

The material used in the construction of your radiator dictates how it operates. Steel units offer a good balance, heating up reasonably quickly and being cost-effective. Aluminium heats the fastest (perfect for highly responsive systems).

From gas to modern systems

While many homes still rely on gas central heating with relatively high flow temperatures, newer heating sources, such as heat pumps, utilise much lower flow temperatures. That’s why we test all our radiators at Delta T50, as it reflects the realistic, "real world" output when your system water isn't scalding hot. This means you can confidently pick a radiator that’s compatible with both traditional and modern heating setups.

Style and flexibility for every room

Whether you have a period property or a contemporary new-build, you’ll find the perfect style to match. You can opt for white, grey, black, brass and chrome finishes. We stock both horizontal and vertical options, so even awkward walls or tricky under-window spaces are covered.

Pro tips for choosing the right radiator

• Know Your BTU: Every room needs a specific amount of heat to stay comfortable, measured in BTUs. Figure out the right size central heating radiator for your room by multiplying the room’s length, width and height (in metres), then multiply that number by 153. This gives you a rough BTU requirement.
• Placement Matters: Fitting a radiator under a window helps to counteract draughts. If you’re tight on wall space, a vertical model is a clever option, especially for narrow hallways or small kitchens. And never forget to check the pipe centres and wall projection to guarantee it fits the first time.
• Add TRVs to Save Energy: Want to warm up just one room without heating the whole house? Fit Thermostatic Radiator Valves (TRVs) to set the temperature on a radiator-by-radiator basis. This is a simple, effective way to shave money off your energy use and keep every space exactly how you like it.
