Infratech has been building electric patio heaters for decades, and the WD-6024 is a clear example of why they dominate this category. It’s a 6000-watt dual-element unit that delivers serious, consistent heat across a wide area. The 304 stainless steel construction and black finish are durable and blend into most outdoor setups without looking like industrial equipment.

The hardwired installation requires a licensed electrician, which is a real commitment. But the payoff is immediate, silent heat with zero emissions. You get up to 90% energy efficiency, and since there’s no gas tank to refill or pilot light to maintain, the ongoing cost is just the electricity it draws. The dual elements mean you can run one or both, giving you flexibility on milder or colder evenings. It’s UL/CUL listed for both indoor and outdoor use, so covered patios, three-season rooms, and even commercial spaces are all fair game.

The main tradeoff is the installation process. You need a dedicated circuit and professional wiring, which adds upfront cost and planning time. But once it’s mounted and connected, the WD-6024 is essentially maintenance-free. Infratech backs it with a three-year warranty, and components are made in the USA. If you want reliable, no-fuss heat for a large patio without the smell or noise of propane, this is the solution.
