When deciding between traditional and modern cast iron radiators, it’s important to consider how each style aligns with a room’s interior design. Traditional radiators boast timeless appeal, featuring intricate detailing and period-specific designs that complement classic or vintage-inspired interiors. Designs characteristic of a specific movement, such as Art Deco or Art Nouveau can serve as a focal point, adding character and warmth to older properties, such as Victorian homes or historic buildings. In contrast, modern radiators offer a sleek aesthetic comprising clean lines and minimalist finishes. Ultimately, the choice between traditional and modern radiators hinges on the interior design vision and whether the space evokes a sense of heritage or embraces contemporary aesthetics.

Interior Design Ideas For Modern Cast Iron Radiators

Modern cast iron radiators can be effectively incorporated into a range of interior design styles, offering versatility across different settings. In contemporary urban apartments, where industrial elements meet modern design, tall and sleek radiators in graphite or metallic finishes complement exposed ductwork and polished concrete floors, adding an edgy yet refined touch. In minimalist spaces with neutral colour palettes, horizontal radiators with smooth surfaces and subtle detailing integrate into the streamlined decor, providing efficient heating without compromising simplicity. 

For eclectic interiors that mix styles and textures, modern cast iron radiators offer a versatile canvas for creative expression, whether painted in bold colours or adorned with a decorative cover to blend with furnishings and artworks. In contemporary high-end homes or boutique hotels, large-scale cast iron radiators with luxurious finishes, such as vintage copper or antiqued hammered bronze, bring forth a feeling of grandeur and refinement. Whether in residential, commercial or hospitality settings, modern cast iron radiators offer endless possibilities for enhancing interior spaces with their combination of style, durability and practical heating solutions.

Traditional Radiator Designs

Victorian 9 Column 

First produced in America in the 1880s, the Victorian 9 Column has a height of just 33cm. This makes it perfectly suited to conservatories, beneath windows and attic conversions where taller radiators may feel overpowering or visually cluttered.  

Rococo 2 Column 

One of the earliest decorative models created, the Rococo 2 Column remains a sought-after choice to this day. Drawing inspiration from the Baroque architecture of 17th-century Italy, its design reflects the era's ornate style. Notable features include the scalloped 'eared' top detail and flared feet, creating a cohesive design from top to bottom. 


The Churchill exudes strength and authority with its bold, robust design. Available in 2 heights, this model boasts exceptional BTU output making it ideal for heating larger rooms. Originally used in government buildings, the Churchill now finds itself at home in traditional and contemporary interiors.

Modern Cast Iron Radiators

Rathmell 4 Column 

The delicate curves between each column demonstrate a paring back in design from the Victorian to Edwardian periods. Available in 3 heights and alternative numbers of columns, Rathmells are incredibly versatile modern cast iron radiators. 

Duchess 2 Column 

Plump columns and a curved top are the result of traditional cast iron radiators colliding with the Art Nouveau movement. The unique appearance of the Duchess 2 Column makes it a popular choice for modern interiors.  


Smooth columns are struck with subtle detailing in their central line that runs from top to bottom on the Peerless. Originally used in hospitals, each section has a wider gap making them easy to clean. 

The Manufacturing Process Of Cast Iron Radiators 

Cast iron radiators have been used to heat homes since the 19th century and, while some aspects of manufacturing have evolved with technological advancements, the fundamental process has largely remained the same.

  1. Design - The process typically begins with the creation of a pattern. Traditionally, this involved crafting a wooden or metal model of the radiator's shape and design. Today, CAD (Computer-Aided Design) software is used to create digital models, which are then translated into physical patterns. 
  2. Sand Casting - Each radiator section is sand cast using CNC moulds giving a high-quality and detailed result. Molten iron is poured into the mould cavity and, as it cools and solidifies, it takes on the shape of the radiator. The cooling process can take several hours depending on the size and thickness of the radiator. Modern pouring systems can precisely control the flow of molten iron, reducing waste and improving consistency.
  3. Paint - Both traditional and modern cast iron radiators can be painted in over 10,000 colours, including those from Farrow & Ball, Little Greene, Cromadex, RAL or Roberson Liquid Metals. At our onsite facility, the first coat is given before the radiator undergoes assembly and pressure testing. Once passed, the finishing paint is applied. A small amount of touch-up paint is dispatched with each order to ensure marks during radiator positioning can be easily repaired.
  4. Finish - Alternatively, models can be finished by hand to provide a hand-burnished or satin-polished finish. This process results in individuality in every piece. 
  5. Assembly - Every radiator is hand-assembled by one of our expert engineers using high-quality seals and connectors. A final quality check is carried out before the radiator is boxed and dispatched.    

Fitting Modern Cast Iron Radiators With A Smart Valve

The introduction of smart meters has changed the face of energy management. The devices provide invaluable insights into energy consumption patterns and empower homeowners to make informed decisions about heating and energy usage. Modern cast iron radiators can be paired with smart valves, striking a delicate balance between preserving the charm of a space and embracing energy-saving technologies. 

Trads' radiators integrate with smart valves from leading brands such as Hive and Nest. When selecting a smart valve, ensure that both the head and body are equipped with a 1/2" BSP fitting to ensure compatibility across the entire cast iron range. This upgrade modernises the overall heating system, making it more responsive to individual preferences and lifestyle needs. By streamlining heating schedules, unnecessary energy consumption is reduced making a substantial contribution to environmental conservation. Through the fusion of historical heating systems with cutting-edge smart technology, modern cast iron radiators are propelled into an eco-conscious future.
