Frequently Asked Questions

Can this heater be used in both indoor and outdoor spaces?

Yes. This model is UL listed for indoor and outdoor installations, including patios, covered decks, commercial dining areas, and semi-enclosed structures. It must be hard-wired by a licensed electrician to ensure safe operation

How much area does the 4000W dual element heater warm?

This model provides effective infrared heat coverage for approximately 80 square feet. Infrared technology warms people and objects directly, making it more consistent than gas heaters in windy or open environments.

Can this heater be recessed into a ceiling?

Yes. The WD-Series supports recessed installations when paired with an optional Infratech flush-mount kit. A qualified electrician must handle the installation to ensure proper clearance, ventilation, and wiring requirements.
