A horizontal cast iron triple-column radiator gives you high heat output with superb heat retention—the heavy cast iron stores warmth and releases it slowly for a cosy, even temperature long after the boiler stops. The triple-column design maximises surface area in a compact footprint, delivering strong convection as well as gentle radiant heat. It’s built to last, has a timeless look that suits period and modern homes alike, and works well with lower flow temperatures (great for efficiency and heat-pump systems).

Where it shines / problems it solves

  • Beats cold spots & draughts: Horizontal placement under windows counters downdraught and evens out room temperature—great for bay windows and exterior walls.

  • High ceilings & larger rooms: Triple-column surface area delivers the BTU needed for lounges, dining rooms and open-plan spaces.

  • Holds heat longer: Cast iron’s thermal mass stays warm after the boiler cycles off, smoothing peaks/troughs and improving comfort.

  • Retrofit-friendly: Standard 1/2" BSP and low skirting-level pipework make it an easy swap for older panel rads in period homes.

  • Low-temp systems: Performs well with lower flow temps (ideal for efficiency setups or heat-pump assists) when sized correctly.
