Infratech has been building electric heaters for over 50 years, and the WD6024SS is their heavy-duty option for serious outdoor heating. It uses 6000 watts of power, which translates to real warmth even on cold, windy nights. The key differentiator here is the marine-grade 316 stainless steel construction. This isn’t a decorative choice. It resists corrosion from salt air, pool chemicals, and coastal humidity far better than standard stainless. If you live near the ocean or have a covered patio that sees moisture, this matters.

The heater is wall-mounted and stays flush against the structure. It operates silently with no fumes or pilot light. At over 90% energy efficiency, most of that 6000W goes directly into heating people and objects, not the open air. The infrared heat feels immediate and natural, like standing in a patch of sunlight. Coverage depends on mounting height and angle, but expect a comfortable zone of roughly 12 to 16 feet from the unit.

One honest note: this is a 240V hardwired unit. You will need an electrician to install it and a dedicated circuit. There is no plug-and-play option. The upfront cost and installation are higher than a portable propane heater, but the trade-off is zero maintenance, no tanks to refill, and heat that works every time you flip the switch. For a permanent outdoor living space, this is the endgame.
