The Infratech WD-4024 SS is the 39-inch dual-element electric infrared patio heater built from durable 304 stainless steel — Infratech’s premium-tier commercial-grade outdoor heating fixture. WD-series fixtures provide more concentrated heat than the standard C-series, designed for recessed installations, premium outdoor heating applications, large-scale coverage needs, and spaces with 8-12 foot mounting heights.
The 4000-watt 240-volt configuration delivers up to 93% energy efficiency with zero emissions — significantly more efficient and lower-environmental-impact than propane or natural gas patio heaters. Compatible with Infratech’s Duplex Stack Switch and Custom Control options for integration with smart-home or commercial HVAC controls. UL/CUL listed for indoor and outdoor use.
Infratech’s bullets explicitly state “components proudly made in the USA and supported by Infratech’s exclusive Three Year Warranty.” Infratech manufactures in Gardena, California — the premium American electric outdoor heating brand. For commercial patios, residential outdoor living spaces, restaurant terraces, and hospitality installations requiring premium American-made infrared heat, this is the WD-series benchmark. Expert installation by a licensed electrician required.
