Fine Arts and Art Installation Design Nova Heater by Chang Hee Lee Heating Nova is a heating radiator unit mostly built from titanium and aluminum. The surface of the heater constantly interacts with the growing heat from the bottom and dramatically marks and records itself with traces or patterns of the expanding heat on the outer surface of the heater as time passes. This marriage between its functional element and the material’s features creates a dramatic juxtaposition of the object, which is about oneness of the object, creating a perfection of a functional identity by beautifully linking its function and the object’s features.
