Radiators were invented to do a job of work, to keep a room as warm as possible. The size of your room will dictate the size of the radiator best suited for it, and you can use single-panel or double panel radiators.
For standard-sized and large rooms, double-panel radiators are by far the most efficient. Single-panel radiators emit less heat because they have less surface area for the heat to come from.
The addition of ‘fins’ inside a double panel radiator – the metal sheets that zigzag between the panels on standard radiators – helps to increase the surface area still further, meaning double panel radiators emit more than double the amount of heat of a single panel radiator.
