What are the pros and cons of cast iron radiators?

As with most high quality products, cast iron radiators are heavy. The dense high quality cast iron from which they are made is much heavier than modern aluminium or steel radiators.
While not as agile and easy to move, it also means they are extremely durable. Superior heat retention, their distinct style and the longevity of cast iron radiators make them a fantastic investment for those looking for high quality long term heating.

Cast iron radiators differ from modern steel or aluminium models mainly in the way they heat and retain warmth. They take longer to reach full temperature, but once hot, they store and release heat for much longer, keeping rooms warm even after the heating is switched off. This gives them a steady, comfortable heat output that feels less harsh than the rapid cycles of most modern radiators.

Modern radiators cool down much faster, leading to more fluctuations in room temperature. Cast iron radiators therefore excel in maintaining consistent warmth and adding style.
