Is this fan energy star efficient?

There is no official data, but I do know I sleep very comfortably with the thermostat set @78 with the ceiling fan running at low or medium speed. Can't remember how long I've had the fans, (maybe 3-5 yrs?) but they are all still quiet and operating beautifully.

Not at all. First, even on high, it has almost no power. You need to be right in front of it to even know it's on. Second, in order for this fan to cool the room down, the air outside has to be much cooler than the air inside. If it's hot outside, it will merely bring that hot air in and weakly circulate it. I find this fan useful ONLY when it's cool outside--like at night.

No, this only provides power. The GRID+ supports fan control through software.

Very efficient only 1200w it's not quiet, a little noisier than a 12000 window unit but not bad. Heater is good.

I would say yes, but it depends on how many AMPs are required to run the fan?

Fans most often do not list their power drain, but a smallish fan like this probably takes 100 to 150 watts or so on high. Remember, however, that energy usage varies dramatically with fan speed, so unless you plan on using it at full blast, the actual wattage will be much lower.

Yes it is, quite efficient. I keep it on the low setting about half way on the thermostat and it heats up my bedroom quite nicely. It's a very large bedroom as well. We have two of these heaters and our electric bill doesn't go up too much. We use these to save on heating oil, which is way too expensive.

No. You need ten times the power minimum under ideal conditions, blue sky 12 noon summer sun to run the fan at 235 cubic feet per minute. A 100 watt solar array for year round usage, under all conditions would be better, in my humble opinion. Better too much than too little. The fan will just draw what it needs. The sun's power is throttled by weather conditions, and time of day. Good luck.

No clear answer to this question. Wattage of fan is not stated, on either the device or the label. Fan is USB powered, but since speed is variable, and the fan can also serve as a USB hub, power consumption could really vary, depending on what else is connected to the fan.

I cannot say it is energy efficient ??? but keeps the den habitable to enjoy and can lower the main furnace (electric heat) so not entire heater has to run as often.

The fan is connected directly to the solar panel with no battery. But for me, it's good. I see no point in ventilating an area when the sun isn't heating up the place.

power is one thing, but if the incoming air doesn't have an exit to move the air through the room the fan doesn't work very well.so remember the airflow through the room is just as helpful as the "power" of the fan

Yes. Some apparently think a better fan is available, but this one has worked fine for me.

I cannot find anything for an energy star claim. the main thing is to use it on a system that does not have aux heat if you are using a heat pump. it is apparently NOT a fully smart system.

Stewart, this fan consumes too much battery power, suggest you use a small fan like used on a computer, mine works fine. Dennis

Contacted Lasko for the answer. It seem's that fans do not have to be energy star rated; micro's, stoves, refrigerator's etc have to be energy star rated. The young lady I talked to said the fan would use wattage that would be similar to a 100 watt light bulb. Hope this helps.

I think it is. Of course the higher the speed the more fan and air noise you have. We use it on the medium setting all the time and forget that it even on.
