Aluminium versus steel radiators: what’s right for your space?

Aluminium radiators are really responsive. They warm up faster than other materials, so you don’t have to wait to feel the difference. Ideal for chilly mornings or in spaces you don’t use all the time.

They can also hold less water than traditional models, which means you’re potentially using less energy than you need to heat them. That’s good news for energy bills, and even better if you’re using a low-temperature system like a heat pump.

Aluminium is one of the most energy-efficient radiator materials around – but it’s also a smart choice if you’re thinking long-term. Many models, like the stylish Soho radiator, are made from recycled aluminium and are usually recyclable at the end of their life. They use less water than traditional radiators, reducing energy use and running costs over time. And because they’re lightweight, they’re ideal for wall-mounted designs or places where weight matters.

Steel brings its own sustainability strengths. It’s tough, long-lasting, and fully recyclable – especially in stainless form. It’s a great choice for busy areas like kitchens and bathrooms, where radiators work hard and need to stay reliable. And if you’re using a shared or open heating system, its resistance to corrosion makes it the perfect low-maintenance option.

There’s no need to compromise on style with either option. Whether you lean towards minimal or classic, both aluminium and steel radiators offer distinctive designs.

Aluminium tends to suit sleek, contemporary spaces. Models like the Tonda have a refined, architectural feel – slim, understated, and perfect for modern interiors. With a wide range of finishes, you can either let it blend in or turn it into a bold feature.

Steel is naturally versatile, and no radiator captures that better than the popular Tuba Classic. With its nod to traditional cast iron styles and softer, rounded edges, it brings real character to both period and modern spaces. Available in a wide range of sizes, columns, and finishes (including soft mattes, rich metallics, and more), the Tuba gives you room to be creative.

Steel radiators usually sit at a more accessible price point, especially if you’re updating more than one room. They’re a solid choice if you want reliable performance and a wide range of design options without stretching the budget.

Aluminium radiators tend to cost more upfront, but they’re designed for efficiency. They can help reduce running costs over time – making them a smart investment for the future.
