Incognito Paint radiator
Delta radiator
One of the slim radiator types is the flat panel radiator. Most of them are vertical radiator but there are also many, which can be installed horizontally. For a limited space, a tubular radiator with completely flat tubes could be the answer as well. They can be bought both as a vertical and horizontal model (see the elegant Rex radiator in the picture below).
These kinds of design radiators can fit perfectly for example behind the door, in the limited space beside the bed or dinner table and in the narrower hallways (see the Real mirror radiator and the Forum room radiator in the picture below).
Thanks to the extensive selection, you can find easily slim radiators which suit every kind of application, from a restoration project to a new build and you can choose from simple, yet sophisticated ones to luxury models. It only depends on your requirements, such as taste and budget (see the Delta stainless steel and the Dream glas radiators in the picture below).
