Radiators with fins at the back of the radiator panel emit the most heat through convection. A small amount is released through the steel panel as well.
This makes the radiator more energy efficient and distributes heat more evenly throughout the room.
Radiators without fins rely solely on radiant heat. This is less efficient and has the potential to create cold spots in the room.
Like double glazing, the design of radiators has changed a lot to ensure maximum efficiency.
Of course, there are a number of different types of radiator to choose from, and you have to pick one that compliments the room. It’ll also need to heat sufficiently.
There are a number of styles to satisfy every home. They are all modified from the original steel panel radiator.
