Infratech has been building commercial-grade patio heaters for decades, and the WD-6024 is a direct reflection of that experience. It’s a 6000W dual-element unit that runs on 240V, designed to throw serious, consistent heat across larger outdoor spaces. The key differentiator here is efficiency: Infratech claims up to 90% energy efficiency with zero emissions, which means you’re not wasting power or dealing with gas fumes.

The heater is built from 304 stainless steel, with components made in the USA. In real-world use, that matters because it holds up against rain, snow, and UV exposure without rusting. The heat output is immediate and directional—you feel it on your skin within seconds, not minutes. It’s UL/CUL listed for both indoor and outdoor use, so you could mount it under a covered porch or in a commercial breezeway without issue. Just note that expert installation is required, so budget for an electrician.

The WD-Series is compatible with Infratech’s Duplex Stack Switch and custom control options, giving you some flexibility in how you manage the heat. The only real limitation is the upfront complexity: you need a dedicated 240V circuit and professional wiring. But once it’s up, the maintenance is minimal and the warmth is reliable. For anyone serious about extending their patio season, this is a long-term solution that performs predictably.
