Infratech SL1624BL 29.50" Slim Line Black Shadow 1,600 Watt 240 Volt 6.7 Amps

Minimalist Stealth with Focused Radiant Warmth

The Infratech SL1624BL Slim Line "Shadow" heater is the premier choice for compact outdoor spaces where a discreet aesthetic is the top priority. Measuring just 29.50 inches in length, this 1600-watt, 240-volt single-element heater (6.7 amps) is specifically designed for intimate seating areas, luxury entryways, and small urban balconies. Despite its small stature, it utilizes advanced quartz-element technology to deliver medium-wave infrared energy that warms people directly, providing a 5x5 foot zone of sun-like comfort that is unaffected by wind or air movement.

Shadow Series Design: Disappearing into the Architecture

A standout in Infratech’s most narrow series, the SL1624BL features a premium Matte Black "Shadow" finish over a durable 304 stainless steel housing. This sophisticated dark tone allows the 29.5-inch profile to practically vanish when mounted against black-painted rafters, dark wood ceilings, or modern steel beams. The high-temperature powder coating is engineered for superior weather resistance and durability, ensuring the heater maintains its sleek, monochromatic look even in harsh outdoor conditions. It is the ultimate "invisible" heating solution for the modern minimalist.

Versatile Installation and Precision Climate Control

The SL1624BL is designed for seamless architectural integration, featuring a slim 4.75-inch width and Infratech’s unique T-slot mounting system. This allows the included black mounting brackets to be positioned discreetly along the back of the unit for a clean, integrated appearance on ceilings or walls. This 1600-watt model is fully compatible with a range of control options, including simple on/off switches, high-amp timers, and advanced solid-state dimmers for custom heat intensity. Operating silently with zero emissions, it provides an eco-friendly warmth that respects the tranquility of your outdoor sanctuary.
