From Carron:
"... traditional radiators are perfectly positioned between the heritage and charm of historic design and the pragmatic efficiency required of 21st century heating.
There is common misconception that cast iron radiators are inefficient and expensive to run compared to modern day counterparts, a point we’d argue. The cast iron sections retain heat for longer and gradually releases the warmth creating a constant warm ambient temperature. Thus, Carron radiators more than match the performance of present heating solutions."
