Question: Is the fan noisy?  Thanks!
Document: Warms my poorly insulated bedroom up well. I like the fact that it has a DC brushless computer fan to push the heat out and is quiet, instead of a AC motor and fan that is noisy. It's small and fits in the small space in between my wall and dresser. I like the metal outside construction. I'm hoping to find this same heater with a thermostat.
it works good in a small area, it will take at least 1/2 hour to heat up a 12x12 room,should get a bigger one, thanks.
I am working a temporary 3 month job... and my office is extremely cold. I keep this on in my office. I usually run it on the slower speed.... and after first getting my feet warm and toasty, I turn it so that it warms my office. I can wear summer clothes and still be comfortable. This was just the perfect heater for me. Thanks Amazon!
It even has a little pre filter on the back before the fan :)
wish it had a timerwish it had a fan settingkinda loud.. on a scale of 1-5 i say its a 3.5 on loudness.otherwise good product.
Purchased this heater and the first time I turned it on it made a terrible clacking sound when the fan spun. I was terribly disappointed as the product has a sleek look and a good weight to it.
This is a great heater. Small footprint, along with good looks. The solid aluminum case stays cool, and the multi-speed fan allows it to run quiet. I use it on the floor next to my desk in the office. Great product.
To be fair it never actually scratched anything on its own but the base is aluminum so there is potential for it to happen. PTC ceramic heaters are self regulating and very safe but have some quirks. This particular unit doesn't have a feature that will keep the fan on for a few seconds to cool the elements when you turn it off, so sometimes if you need to move the unit it will take a few minutes to cool enough for it to turn back on.
If you need a primary heat source to heat a room though the winter and not just a space heater, I recommend a heater that does not use a fan because all electric heaters are about the same efficiency so why get one that's going to make noise the entire time its heating? I feel that most of the negative reviews are resulting from people trying to use this in an application it wasn't designed for.
Very few, but the fan might be a little loud for someone who prefers no fan. It's about as loud as a very good vent fan in a bathroom.2. Even though it only gets hot on it's face, it's a little tricky to pick up and move when hot. Could use a recess handle in the back.3. No tip switch, but the overheat switch may work if it falls on its face. I haven't tested that. :-)
Answer: Absolutely not. Obviously any fan makes some noise but this heater is quiet on both the lo & hi settings. We use it occasionally and primarily in our bedroom. It warms the room well and we both sleep with no noise problems with the fan.
