    When it comes to choosing an electric patio heater, reliability is key. If you're living near marine environments or coastal areas, you need a patio heater that can take on the corrosive sea air without breaking down.

    Introducing Infratech's WD Series Dual Element Marine Grade Electric Heater, the epitome of durability and corrosion resistance. With 316 Marine Grade Stainless Steel, this heater is built to withstand the harshest environments, protecting your investment for years to come.

    Designed for spaces with mounting heights of 7' to 9', this heater can be seamlessly flush mounted to the ceiling with the optional flush mount kit, giving your space a sleek and sophisticated look. In mildly cold climates, it can warm up an impressive 8 x 8 ft area, creating a cozy oasis for you to enjoy.

    By utilizing quartz elements, these electric heaters emit safe and clean wavelengths of light that are efficiently absorbed by solid objects. 90% of the energy consumed is transformed into luxurious infrared heat. No more worries about heat disappearing into the wind. Whether you're using it indoors or outdoors, you'll experience the ultimate form of warming sophistication.

    Indulge in the soothing warmth of one of the best electric heaters on the market. Our heaters are built to last, proudly made in the USA, and designed with your comfort in mind. Shop now with our free shipping offer on all Infratech Heaters!

    The WD 33" Marine Grade Heater is also available in Commercial Grade Stainless Steel.

    Note: Less heat is provided in extremely cold or windy areas. Please see the recommendations below and the Infratech Heat Coverage Guide for setup recommendations.

    Heaters greater than 240 Volts are for “Commercial Use Only. Risk of fire. Do not use as a residential or household heater.” This is for your safety.

    Standard Stainless Steel 120V/240V models are usually in stock and ready to ship. Custom voltages are special orders with 2-4 Weeks Manufacturing Lead Time.
