Electric Infrared Patio Heater · 4000W 208V 39 in · Dual Element White · Infratech WD-4028-SS-WH
What this product is for
This electric infrared patio heater is for warming outdoor or semi-sheltered areas such as patios, restaurant seating, terraces, covered decks, and similar spaces where direct radiant heat is preferred over forced air. The WD-Series dual-element design is intended for larger coverage areas and more concentrated heat than smaller single-element models.
Use for
Use for 208V outdoor heating projects where a 4000W heater matches the available electrical service and the application benefits from a 39 in (991 mm) dual-element fixture. Commonly used in hospitality, multi-residential amenity areas, and higher-end residential patios. Typical guidance: dual-element Infratech heaters are often installed with compatible custom controls or duplex/stack switches to allow half-power or full-power operation, depending on conditions.
Avoid for
Avoid for locations that only have 240V service unless the heater model is specifically matched to that voltage. Avoid using this as a whole-space indoor heating substitute or where mounting clearances, weather exposure, or control requirements have not been reviewed. Actual performance depends on installation conditions, mounting height, wind, ambient temperature, and local electrical code.
Best for
Best for contractors and specifiers needing a white-finish infrared heater for visible surface-mounted outdoor applications, especially where a shorter 39 in body is preferred over longer heater formats. It suits projects that need concentrated radiant heat with a cleaner architectural appearance.
Installed in
Typically installed in covered patios, pergolas, restaurant canopies, outdoor lounges, clubhouses, and commercial entrances. Manufacturer guidance for the WD-Series indicates mounting heights up to 12 ft (3.7 m), subject to the installation manual and site conditions.
Why this product exists
This model exists for projects that need more intense radiant output from a compact dual-element heater on 208V power. Compared with lower-wattage or single-element units, it is aimed at larger-scale outdoor comfort heating while keeping the fixture length at 39 in (991 mm).
Compared with similar products
Compared with Infratech W-Series single-element heaters, the WD-Series is built for more concentrated heat and higher mounting capability. Compared with 240V versions of the same 4000W platform, this 208V model is intended specifically for 208V electrical systems and draws approximately 19A at rated voltage. White-body versions are created by adding the white suffix to the base WD-4028 stainless model designation.
