- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.

Pros
- 16.7 A leaves room on a 25 A circuit; the 6,000 W heaters land on 35 A on one feed by the 125% math, and your inspector decides
- 39 inches long, against 61.25 inches for the WD-6024
- Owners report it covering 'my 8 x 10 foot patio just fine', which matches Infratech's average chart
- The same printed element life of up to 5,000 hours
Cons
- Coverage is one seating group: Infratech's own chart stops at 8 × 10 ft on an average night
- Same 102-in ceiling need as the 6,000 W
- An owner calls it 'a BRIGHT RED light': it is a visible glow, and one venue owner disliked it
- Sold on Amazon by third-party sellers rather than Infratech
Less heat than the price suggested, and hard-to-find electrical specs. One owner says it 'puts out way more light than heat' and calls it 'a BRIGHT RED light'; another expected it to be hotter for the money; a third could not find the electrical requirements for an electrician.

“Excellent electric heater. This 39” model has two bulbs, so you can use one bulb using 2000 watts or both bulbs & get heat at 4000 watts for those chilly nights. It covers my 8 x 10 foot patio just fine. If you have a larger area get the 61” model.”— Jeffrey Swartz, Amazon · Verified owner
