Extreme Durability and Luxury Comfort From a Marine Grade Electric Heater

infratech authorized dealer

Struggling to keep your outdoor living spaces warm with an electric heater that easily breaks down? You don't want to settle for a heater that won't last in the sea air or saltwater environments.

You want something powerful, efficient, and long-lasting while you enjoy the outdoors with friends and family.

Choose Infratech's CD 3000 W Dual Element Marine Grade Electric Heater for extended durability in harsh weather conditions. This new Marine UpGrade features corrosion-resistant, robust 316 stainless steel to increase the lifespan of your Infratech heater.

This patio heater is an excellent choice for wall or ceiling mounting, and can even be flush-mounted with the optional frame, like the W series heaters. Built with inset mounting brackets, it has a floating appearance when wall or ceiling mounted.

Infratech's infrared heater is more efficient than traditional heating systems as it smartly warms solid objects within a 7 x 7 ft area. With Dual Element, you can indulge in twice more heat as Single Element heaters. Install a Duplex Stack Switch to set its heat at high or low. More advanced control options are also available.

Rely on one of the most affordable, yet sturdiest electric heaters on the market. Buy now and take advantage of our free shipping offer!

This heater is also available in other sizes: Infratech CD Series Collection

The best angle to install this heater is approximately 45º. If installed outdoors, it is best to install it at the "cold side" for efficient heating and under a protective roof or weather cover, whenever possible. Even with its all-weather construction, your heater will last longer and look better if it is protected from rain and snow.
