Since column radiators have a larger surface area and more space between each column they are very effective at heating the air around it.
Whereas if you think about the build of standard single or double panel radiators (convector radiators) they have a solid steel front panel and one or two sets of convector fins attached to the back.
This means that as hot water enters a panel radiator, heat is transferred into the convector fins which help to increase the surface area and circulate warm air around the room through convection currents. All good so far.
The problem is that the heat that is transferred into the convector fins is kind of a waste. Column radiators don’t have additional metal parts to heat up to help them do their job. Instead, the column radiator is like one big set of convector fins!
So the column detailing not only looks beautiful and gives the radiator more character but it also means that more air is heated up at a faster rate causing the convection cycle to heat the room quicker than panel radiators. And if your home is heated quicker then you may not need to have the heating on for as long which could help save you money on your heating costs.
