The WD Series features two quartz heating elements instead of one, delivering significantly more concentrated heat output from the same 39" fixture length. This makes the WD5024SS ideal for larger coverage areas, higher mounting heights (8–14 feet), and applications where greater heating intensity is needed — such as commercial dining patios, resort spaces, or covered outdoor rooms with taller ceilings. Single-element W Series heaters are better suited for lower mounting heights and smaller, more intimate spaces.

Yes. The Infratech WD5024SS is UL Listed for both indoor and outdoor use. It produces zero combustion byproducts — no carbon monoxide, no fumes, and no emissions — making it completely safe for enclosed or semi-enclosed indoor installations such as sunrooms, covered atriums, garages, or commercial kitchens. Always follow the clearance-from-combustibles guidelines outlined in the installation manual.

The WD5024SS supports four mounting configurations: wall mount, ceiling mount, pole mount, and stainless steel flush mount. The heater includes 6" × 6" stock brackets that provide the required 6" clearance from combustibles in a straight-down ceiling mount. Optional custom brackets in 9" and 12" lengths are available for tilted installations or custom setups, as well as narrower stainless steel brackets (3½" × 9" or 1½" × 6") for 4x and 2x lumber applications respectively.

The WD5024SS is compatible with a broad range of Infratech control options. Basic setups can use a high-amp timer, duplex-stack switch, or dual infinite controls for simple two-element management. For advanced use, Infratech offers solid-state electronic controls, universal control panels, and home management system integration that allow for infinite heat adjustment, zone control, and smart home connectivity. Solid-state controls are recommended when operating multiple heaters simultaneously.

From a mounting height of 8–12 feet, the WD5024SS effectively heats an area of approximately 90 square feet — roughly a 9' × 10' space. Because infrared radiant heat warms objects and people directly rather than heating ambient air, it feels noticeably warmer than its square footage coverage might suggest, especially in open or partially open outdoor environments where conventional heating would be lost to air movement.

Yes. The WD5024SS is constructed from durable 304 stainless steel (in the stainless finish variant) or cold-roll steel with a powder-coat finish in color options, both designed for long-term outdoor exposure. The electric infrared design has no moving parts, no fuel lines, and no combustion components that can degrade from moisture or temperature swings. It is engineered for all-season outdoor use across residential and commercial settings.

Operating cost depends on your local electricity rate. At 5,000 watts (5 kWh per hour), a typical rate of $0.13/kWh means roughly $0.65 per hour of full-power operation. Infratech's 90% energy efficiency ensures nearly all electricity consumed is converted directly into usable heat. With no fuel to purchase, no tank refills, and low maintenance costs, the WD5024SS typically offers a lower total cost of ownership than comparable propane or natural gas patio heaters.

Infratech warrants the WD5024SS to be free from defects in materials and workmanship for one year from the original date of purchase. This warranty covers manufacturing defects under normal use and installation conditions. Each quartz heating element is independently rated for approximately 5,000 hours of use. For warranty claims, keep your original purchase receipt as proof of purchase date, and contact Infratech or your authorized dealer for service support.
