Flat panel radiators generally make great use of vertical space on your wall. The large surface area allows for high heat output on designs that are flat to the wall. Aluminium constructed models in particular, such as the Hudson Reed Rapture or Premier Myrtle, heat up quickly and radiate heat efficiently. They can be discreetly located behind a door or made a feature of with the wide choice of colours and panel shapes. Some like the Hudson Reed Ceylon almost have a textured surface. Boring radiator designs are a thing of the past.
