Infrared Dual Element Patio Heater · 4000W 208V · 39 in Black Finish · Infratech WD-4028-SS-BL
What this product is for
The Infratech WD-4028-SS-BL is a dual-element infrared radiant heater designed for medium-size outdoor and indoor comfort-heating zones where fast, directional heat is preferred over forced air. It is built on the WD-Series platform for more concentrated heat output in larger seating or gathering areas.
Use for
Use for covered patios, restaurant seating areas, hospitality spaces, vestibules, garages, workshops, and commercial exterior zones where 208V power is available. It is commonly selected when you need a black-finish heater that blends into darker ceilings or architectural surfaces.
Avoid for
Avoid using this heater where the supply voltage does not match the 208V rating, in locations that do not meet manufacturer clearances, or where broad whole-room heating is expected like a forced-air system. It is not the right choice when a low-amp branch circuit is the limiting factor.
Best for
Best for electricians and contractors specifying directional radiant heat for medium-to-large covered areas. Dual-element WD-Series models are also commonly paired with compatible controls or switching arrangements where staged heat output is desired.
Installed in
Typically installed wall- or ceiling-mounted in covered outdoor living areas, restaurant patios, commercial terraces, and similar spaces. Manufacturer literature lists WD-Series dual-element heaters as suitable for mounting heights up to approximately 12 to 14 ft (3.7 to 4.3 m), with WD-40 models commonly used around 8 to 12 ft (2.4 to 3.7 m), depending on layout and comfort target.
Why this product exists
This heater exists for projects that need concentrated radiant heat without moving air. Infrared heat warms people and surfaces directly, which is useful in semi-open spaces where conventional space heating is less effective.
Typical guidance: a 4000W dual-element patio heater is often used to cover roughly 8 x 10 ft (2.4 x 3.0 m) when mounted at the recommended height. Actual comfort coverage depends on mounting height, wind exposure, ambient temperature, insulation, and local electrical code.
Compared with similar products
Compared with single-element heaters, this WD-Series dual-element model is intended for more concentrated heat in a wider occupied zone. Compared with higher-wattage WD-50 or WD-60 models, it suits smaller coverage areas and lower connected load. The black finish offers a cleaner visual match for dark architectural applications, while marine-grade versions are better suited to harsher coastal environments.
