Column radiators earn their place twice over - they throw out serious heat and they look deliberate doing it. The DQ 4 Column Cast Iron Horizontal Radiator 355mm - Premium Colour carries the classic multi-column profile with crisp, modern execution.
Widths and heat output
This radiator is 355mm tall and comes in 35 widths. Outputs are quoted at ΔT50; room coverage assumes average insulation, so if you are between sizes go up rather than down. Ask us if you would like a hand sizing it.
