Aluminium Radiators, low prices online and free UK delivery! Aluminium is great for making radiators, because it’s highly conductive of thermal energy. This thermal property means that the heat in the water is transfered to your room much sooner than any other material. Because of this they save you money on your heating bills compared to other materials, and also play a part in helping you look after the environment due to how easy they are to re-cycle! They sound great on paper, and as you can see below, in reality they look brilliant as well!
