The Infratech WD-Series Marine Grade 6,000W Electric Patio Heater is built for environments where corrosion resistance is critical. Featuring a Marine Grade stainless steel housing rated for salt air, coastal exposure, and high-humidity installations, this dual element heater delivers the same silent infrared warmth as the standard WD-Series — engineered to last in the harshest outdoor conditions.

This 6,000W model covers 121 sq. ft. with no noise, no emissions, and instant-on performance. Ideal for coastal homes, poolside patios, marinas, and commercial outdoor spaces. Available voltages: 240V/208V/277V/480V.

Please Note: This heater must be hard-wired by a licensed electrician to a dedicated circuit. It is not a plug-in unit and must be professionally installed for proper performance and safety.
