Although this Copper Hanging Halogen Square Heater is manufactured from steel, its copper finish is designed to look tremendously attractive in any outdoor situation, particularly a pergola or gazebo. The copper has a natural warmth all of its own and it is the perfect accompaniment to the glowing halogen lamp of this energy efficient heater. Two heat settings and a light are controlled by soft touch rather than switches, and the powerful eco-friendly and long lasting 2000w lamp heats only people while emitting no fumes.
