Is there a difference between the 2 and 3 blade ecofans? We're heating a pretty large room.

I have a fairly large area to heat. I guess I just looked @ the physics; decided that the larger configuration to include 3 blades would be the answer. We are extremely pleased with our unit and it has served us for many years. The one that was reviewed was an unit for a friend.

Read my review.... but, then.... enjoy your ecofan... no matter how many blades it has....

circulates more air than a two blade, but the core the fan is on is bigger and abosorbs more heat so yes the bigger the better.

I believe there is, but my opinion is based on the comments I read before I purchased the 3 blade. It seemed the 2 blade purchasers were not happy, but the 3 blade purchasers were very happy. My room is 24 x 32 basement and I love the difference my fan has made.

3 by a large margin. Only get the 2 if you are space limit. The 3 is much more versatile.

I wish I could help you with that but I'm not certain. I certainly haven't noticed a difference in my electric bill, and my son uses this fan every night. The one negative I have to say is that it was only used for a couple weeks before it started making a very annoying noise while oscillating. It has therefore only been used in a fixed position since. If you want a good oscillating fan, this may not be the one for you.

You can't tell without having degree-day information over the same days last year and this, plus adjust for different usage rates. I just do it because it's the right thing to do to get greener. People in my neighborhood have been scammed by powered fan sellers and have 3-4 electric fans in their roofs, often within a few feet of each other. They are fighting each other and swirling the air in the attic tornado - while using more electricity! This one 30-watt fan is more than enough for my 1900 sq ft house. I used to have one electric fan in a 2600 sq ft house in Tyler, TX.

I would also recommend the larger fan. I installed the 110cfm fan in our 10 x 12 bath and if works great.

I was wondering the same and also that given the fact that both have the same motor, I was wondering if the 4th blade would hit the overall performance. But since JR felt it even a bit quicker then all seems to be ok.Thanks both!+Alfredo

Im sorry Amy, but I don't know about the other unit. What I can say about this is its silent on level one, barely audible at level 2, and a little loud at 3 but it moves lots of air at 3. It has a separate carbon filter which is nice b/c they require frequent changing.I like how this unit has an auto setting, allowing it to go up or down depending on the air quality. I also like how it can turn the plasma function off while still filtering air

I don't use the fan everyday, so I can't really say.But based on the times that I have used it. I have not seena hugh difference in my electric bill. Hope this helps.

To be honest, i don't know. Couldnt tell a big difference in my bill. I do not compare this to an air cooler though. Unless mine doesn't work properly, it is no different from any other fan to me. I had bought it because everyone was saying it was like an air cooler. I could of bought a cheaper fan the does the same thing. Just so you know.

My experience with both machines I bought is that the temperature appears (subjectively) to be lowered, and not just in the line of fire from the fan. They also appear to alleviate sniffles and congestion to some extent. sometimes working better at a lowere rate of fan speed. As an objective measure, I have not noticed a drop in temperature on the thermostat (in another room).

Can not compare to ecoheater but it is well known they get hot, these envi heaters do not get hot enough to cause trouble. I do find them very inefficient, they can hardly keep up with the rest of the house. To cut bills on heating you would need at least one for every room in the house and not just the colder areas.

Cannot answer about any comparison, but I like this fan. I bought it mostly for my tent but indoor plug-in use is a bonus and that was part of my purchase decision. I don't remember what I paid....almost 2 yrs. ago.

they say that its because they use infared heat but I personally don't know if there is a difference I bought mine because it uses less energy than some of the other types of heaters

To be honest I didn't notice much difference. I have 2 but cannot remember which model numbers are the 2 I purchased. One has the heating attachment and the other does not. The heat is the only difference between the 2 I have.

No. You get to choose from among 3 distinct speeds. The only drawback to that is that even the slowest speed might push too much air to suit your needs. However, if you want a fan that really "blows" (in the positive sense of the word), this is IT!

I would go with the 110. The cost difference is fairly insignificant so I always try to go a little larger than the calculation calls for. These are great fans. I've bought quite a few for other people and have 2 in my house. Hope this helps.

That's the right fan description but the wrong picture. The number of blades is not a requrement for a wood stove. Different models are set for different heat ranges, i.e. GS is for gas stoves. It won't handle the extremes a wood stove is capable of. Read the descriptions. Two blades will pump 100 fpm. Three blades will handle 150 fpm. You want 3 blades. This isn't a house fan. Don't expect a lot of speed. You will feel the heat flow across the top of the stove and rise into the room to the side of the stove. I have a 3 blade 802. It is a delightful addition to the top of my 1976 Vermont Castings Defiant. It's also a great conversation starter.
