Warm Your Space With an Electric Heater That Exhibits Extreme Durability

infratech authorized dealer

Extreme climates can be unforgiving for a regular outdoor heater.

While most heaters may work fine in non-saline environments, they may rapidly corrode and rust when installed near coastal areas. This can make it difficult to find a reliable long-term patio heater, particularly if the warranty period has expired.

For extended lifespan in extreme climates, opt for Infratech's new C Series 61" Single Element Marine Grade Electric Heater with 316 stainless steel construction. It offers marine-grade durability and corrosion-resistant capabilities.

Indulge in premium outdoor living as this patio heater offers versatile installation on walls or ceilings. It can even be recessed with an optional flush-mount frame for an even sleeker look. Not only that, but smart home integration is also available!

Infratech's industry-leading infrared heater gives superior performance by directly heating solids, not just the air, covering 8 x 8 ft of space with the 3000 W model and 10 x 10 ft with the 4000 W heater. While it may lose some heat output during extreme weather, you can check out the Infratech Heat Coverage Guide for advice on setup and coverage. Note that heaters of more than 240V are for commercial use only.

Heat your outdoor space with one of the best electric patio heaters in the market and regret nothing when it comes to durability. With free shipping, get the best deal here. Shop now!

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

Marine Grade Electric Heaters have a lead time of 1 to 2 weeks. Special orders with custom voltages will take 2 to 4 weeks.

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.
