Why infrared heat?

A heated quartz element emits a safe, clean wavelength of light that is only absorbed by solid objects, transferring heat directly to a person, table, or floor rather than heating the air. For this reason, infrared heat can be distributed very evenly, and will not simply "blow away" in windy or drafty conditions. Infratech medium wave quartz element heaters are 93% efficient and emit a barely discernible, pleasing glow that will not affect the ambiance of your gathering – unlike competitive short-wave or halogen electric heaters that produce a very harsh glare or bright-colored light.

Cost of Operation and Maintenance

Operation:

It’s simple to determine the cost of operating an Infratech heater—multiply the rate charged by your local utility company by the wattage of your heater.

Your Utility Rate X Wattage of Your Heater = Cost of Operation

EXAMPLE: Your utility charges $0.15* / kilowatt hour (kW) X 3 (for a 3000 watt heater) = $0.45 / hour

***This is the National Average. Utility charges will vary.***

 

Maintenance:

Unlike traditional gas heaters, Infratech electric heaters are virtually maintenance-free. For long-lasting use, we recommend once a year to spray the heater with a hose and wipe it down. Our elements are rated to last 5,000 hours, plus they are simple and inexpensive to replace.

Super Low Quality/Unacceptable QC
Color: Black, Size: Wheel-6 Panel
I spent probably about an hour putting it together, only to take it right back apart and pack it up to return. The dimples for half the poles were on the wrong side (double and triple checked to make sure they couldn't be spun around. The threaded ends for the wheels were freely spinning on all but 2 wheels, making it impossible to actually tighten them fully. Once it was all put together, the screens could not be folded up to neatly put it aside when not in use. All in all, this was shamefully low quality for the money spent.

Not as tall as anticipated
Color: Black, Size: Wheel-6 Panel
Definitely not 6 feet tall, more like 5 1/2. Very sturdy and the fabric is thick. Works well for what we're using it for.

Easy assemble and not to big!
Color: Black, Size: 132in-Large Metal Base
I bought this because I fo a lot of zoom/teams meetings and work just mandated no false backgrounds (don’t ask) soooo to hide my real home and allow others to roam free while I work I got this. Easy to assemble although you will need some space. I thought I might be to big at 11’ wide as I have a small desk area but actually it’s perfect and could use a couple more panels. Leaves just enough room so I’m not completely cocooned - I can move my chair and get up walk behind chair and exit space. Great deal and tax deductible!
