Infratech WD5224MG 48" Dual Element 5,200 Watt 240V 21.67 Amps Marine Grade Infrared Heater

Maximum Dual-Element Power in a 48-Inch Marine Profile (5200W / 240V)

The Infratech WD5224MG is a high-capacity powerhouse, delivering 5200 watts (21.67 amps) from a 48-inch chassis. This unit is specifically engineered for high-exposure coastal environments where space is limited but maximum thermal intensity is required. Optimized for mounting heights of 8–12 feet, it projects a premier 9x9 foot comfort zone. Its dual-element design allows for a shorter overall length compared to single-element models of similar wattage, making it a versatile choice for luxury yachts, seaside balconies, and upscale coastal dining areas.

The Marine Grade Collection: Elite 316 Stainless Steel Resilience

Constructed from 316 Marine Grade Stainless Steel, the WD5224MG is built to withstand the harshest saltwater conditions. This premium alloy offers superior resistance to chlorides and salt spray compared to standard 304 stainless steel, effectively preventing the "tea staining" and pitting common in coastal zones. The brushed metallic finish provides a sophisticated, professional aesthetic that maintains its integrity and appearance even when exposed to constant maritime humidity and salt air.

The WD-Series Advantage: Optimized for Flush-Mount and Precision Control

The WD5224MG features a deeper housing design compared to the CD-Series, which provides superior ventilation when recessed into a ceiling. This makes it the preferred model for seamless flush-mount installations (flush-mount requires an optional 316 stainless steel frame). As a dual-element unit, it offers exceptional control flexibility; it can be paired with a Duplex Stack Switch for high/low heat settings or integrated into a solid-state control system for infinite variable adjustment and home automation. Operating silently with 90% energy efficiency, it provides a safe, powerful, and durable heating solution for demanding coastal environments.
