Stove Booster DWF-1 Doorway Room to Room Heat Helper Transfer Fan by Professional Grade Products, 110 CFM

My kitchen was always cold. This cured the problem. It does make noise. Like the pink noise between FM channels on an old analog tuner with a low hum. It is not loud, but plainly audible.My other biscuit fan is virtually silent but this moves twice as much air. I added a line switch for when I need total quiet.It also does not have a pivot on the mount that my old biscuit fan did. It will only point directly straight.

Works as expected but a little noisy.

Very effective at moving air and remarkably well considering the small size. Runs quitely also. My only suggestions would be that the instructions provide a little more detail. Common sense got the installation complete but more detailed instructions would be preferred.

I received this model to replace one that I have. When it arrived I did not inspect it closely enough. After taking down the one I have I started to assemble the one I received. come to find out it was used. All the screws were not there and the wall mount bracket what cheep. Well, what I did was fix the one I have, oil it a bit, tighten the swivel mount and put it back up. Works as good as new. Now I am stuck with the parts required used unit I received from Amazon. Very disappointed. We have purchased many items from amazon, but nothing like this.

This little fan is mighty. It works great for moving heat from one room to another in the wintertime. I place it up in the corner of the door that goes from the room with the heating stove to the larger kitchen and living room and it moves the heat from the small room to the other rooms nicely. I am well satisfied with it.

I bought 2 of these model plus 2 of the "Achla Minuteman" 55 CFM fans at the same time to compare. I can't speak of the durability of either since they're new, but I believe the motors on all these fans are only designed to last for about 2 years of use. The best way for me to describe this fan is to compare it to the other model.Both looked about the same. The housings and fan blades were almost identical and differed only in minor decorative details. Both were equally easy to assemble: 2 screws into the doorway/wall through the bracket, and one bolt (Minuteman) or plastic plug (Heat Helper) through the fan housing and fan blade guard to hold them onto the bracket.Both had cords that plug into the fan housing. The Stove Booster model had an angled plug that snugged up against the housing and seemed more practical than the 90-degree bend in the Minuteman model, though neither style of plug was functionally better or worse. The Minuteman card had a switch near the wall plug end so it can be turned on and off while remaining plugged in; the Heat Helper has no switch so you unplug it to turn it off and plug it in to turn it on. The Heat Helper cord was about 1 foot longer than the Minuteman cord, but at around 11 feet in length, both were plenty long for my needs.Brackets: The Minuteman fan had a hinged bracket so the fan can be aimed to the left or right. The Heat Helper bracket was fixed in place so the fan blows in one direction only. Both fans blow in one direction only, so you have to bear in mind which way you want the air to be blown when you decide which corner of the fan housing and which side of the doorway to mount the bracket on.Hardware quality: The Minuteman fan came with 4 long metal bolts and nuts to hold the front screen and the rear screen to the fan housing. The Heat Helper fan came with plastic plugs shaped like bolts with small fins on that you push into place to hold the screens to the housing. Maybe the plastic things are faster to pull off, but they seemed far less durable and useful to me than the bolts.Packaging: The Minuteman fan came in a sturdy cardboard box with separate spaces for the cords and hardware, and an instruction booklet with detailed but simple installation instructions, diagrams, and warnings. The Heat Helper fan comes in a plastic bag with a page of warnings but no installation instructions (though installation ought to be easy to figure out without instructions). Both brands arrived undamaged at my home, but I imagine the Minuteman is more likely to arrive safely due to the extra secure packaging.Power: The Minuteman fan claims to move 55 cubic feet of air per minute and the Heat Helper fan claims to move 110 cubic feet of air per minute. Consumption maybe is about the same - the Minuteman fan claims to use less than 15 watts, and the Heat Helper claims to use 18 watts. The Heat Helper fan did put out a far stronger blast of air than the Minuteman, but I felt that the 55 CFM was sufficient for the rooms we needed the fans for.Noise (my greatest concern): The Minuteman fan was FAR quieter - "whisper" quiet - I could barely hear it when it was running. The Heat Helper fan was not horribly noisy, but it was loud enough that its constant sound immediately bothered us when it was mounted in the living room doorway where we sit all night every night. The Heat Helper fan is described by their seller as "quiet", which is very relative/subjective; to me it was about as loud as a loud fast fan in an old desktop computer (much louder than a quiet fan in a new desktop computer). For this reason, plus the general lower quality and unmovable bracket, I returned the Heat Helper brand fans. I felt I got a lot more for the 10% higher price with the Minuteman fans.

Was easy to install and moved the air as I expected. There is only one speed but it was adequate to move the air to the bedroom from our pellet stove. Would consider buying another.

Not as quiet as stated. In fact, I'd say the fan is just plain loud. And there is no on off switch so that means unplugging when you want it off. Pain in the you know where.
