Rasmussen – Bromic Cobalt Smart-Heat™ Electric Patio Heater – 4000W & 6000W Dual-Element Stainless Steel Outdoor Heater

The Rasmussen – Bromic Cobalt Smart-Heat™ Electric Heater is a high-performance, entry-level outdoor infrared patio heater that delivers strong, consistent warmth in a sleek stainless steel package. Designed for wall or ceiling mounting, the Cobalt series brings Bromic’s proven Smart-Heat™ engineering to patios, decks, balconies, and commercial terraces that need reliable heat without a lot of visual clutter.

Built from 304-grade stainless steel and powered by dual quartz heating elements, the Cobalt provides efficient radiant heat for outdoor spaces up to roughly 130–160 sq ft, depending on wattage, mounting height, and exposure. The extended body and parabolic reflector help project a wide, directional “wall of heat,” while the translucent quartz elements emit a soft amber glow that feels warm and inviting.

Available in 4000W and 6000W models, the Cobalt series is compatible with Bromic wireless On/Off and Dimmer controllers, allowing you to manage one or multiple heaters from a central location or integrate them into smart control systems. Whether you’re upgrading a residential patio or specifying heaters for a café terrace, the Cobalt Smart-Heat™ Electric offers clean design, durable construction, and serious performance at an accessible price point.
