Stealthy Mid-Size Warmth with High-Efficiency Infrared Power

The Infratech SL2424BL Slim Line "Shadow" heater is the ultimate choice for outdoor spaces that require potent heating without a bulky visual footprint. Measuring 42.50 inches in length, this 2400-watt, 240-volt single-element heater (10.0 amps) is precision-engineered to warm medium-sized seating areas, covered balconies, and modern outdoor dining nooks. Optimized for mounting heights of 7–9 feet, it provides a consistent and comfortable heat spread across approximately 7x7 feet. By utilizing advanced quartz-element technology, the SL2424BL emits medium-wave infrared energy that warms people directly, ensuring a sun-like comfort that is not affected by wind or air movement.

The Shadow Series Aesthetic: Seamless Architectural Integration

Part of Infratech’s exclusive Shadow series, the SL2424BL features a premium Matte Black powder-coated finish over a durable 304 stainless steel housing. This dark, sophisticated tone is specifically designed to blend into black-painted rafters, dark-stained ceilings, and modern steel structures. The high-temperature finish is built to withstand extreme heat and environmental exposure, providing superior corrosion resistance while maintaining its refined, monochromatic look. This heater allows your design to remain the focal point by offering "invisible" warmth that complements modern minimalist and industrial-chic aesthetics perfectly.

Versatile Installation and Intelligent Climate Control

The SL2424BL is built around Infratech’s signature Slim Line housing, featuring an ultra-narrow 4.75-inch width that preserves the clean lines of your structure. The 42.50-inch linear profile is exceptionally versatile, fitting easily into architectural niches where larger units would be visually overwhelming. Equipped with a unique T-slot mounting system, the brackets can be hidden along the back of the unit for a sleek "bracketless" appearance. This 2400-watt powerhouse is fully compatible with a wide array of Infratech controls, from simple on/off switches to high-amp timers and advanced solid-state dimmers for precise heat intensity management.
