Is this quiet when it turns on and off? Can you hear it at all?

No , there is no sound at all . You can program it to come on in the early morning and turn off at afternoon or night .

There is a relay arm in the thermostat that makes a loud click when thermostat is switching on or off. It may be that those reporting no noise have had the thermostat housing sound-insulated.

no its actually a pretty loud click. my wife has asked a few times, "what's that noise?" We've gotten used to it.

It is quiet. I have mine programmed to heat a bathroom floor before I wake up and shut down when I leave.

You hear a click on the thermostat going on and off but you don't hear noise during operation.

It's practically silent if the fan is off; otherwise, it has a soft "fan" sound.

While I dont have the exact specs, I can tell you that its nearly silent when it switches on. I have it sitting on top of my unit sucking air straight out of the receiver vents and its very quiet. I really don't think noise is an issue with this thing. Doesn't even produce vibration noise.

It is very quiet. It does have a fan and occasionally it is loud if the computer is "working hard". I would say the fan is on very low 90% of the time and you can barely hear it.

Mine is quiet but it depends on which setting you use. If it's on the lowest and is still very loud then there is an issue.

I do not hear a lot of noise. I have noted as it is on longer. It does not beep.

Its not loud at all - I have it in my living room where my TV is as well and it barely makes more than a bit of a very light hum when it's running (I use the auto setting so it kicks on periodically when it needs to and usually in a low mode although once in a while higher). I can barely just hear it when there is nothing on like a tv or radio and sometimes miss it all together if I am focused on what I am doing. Can't hear it at all with the TV on.

It doesn't make a sound when turning on or off. It has a low whirring sound when running but it's very faint so perfect for sleeping. It will last all night too.

No, it dose not make any sound at all. I love it. There is a timer and there are multiple choices that you could choose. It is very compact so you could close it up and put it away.

Actually, no. It's quiet silent. I was surprised to hear it. I thought it would be way more noisy.

It does make a sound but its barely audible. I leave mine in my master bathroom and cannot hear it when its running. If I'm standing next to it, I can hear a very faint hum.

It is quiet to me. Just a light fan noise. It is easy to forget that it is on.

its not quiet. You definitely hear and notice when it kicks on or off...but I sleep comfortably ...it does not wake me up

Not at all. On the first 3 settings you can not hear it at all. On the fourth setting you can hear airflow as you would from a fan on high but still not noisy. It is so quite and works so well I just ordered a second one for another room in my house. 100% happy with this product

It's dead silent. I have never heard any noise from it. I have two of them. Same result. Hope this helps.

this is the only unit i have ever had so it is hard for me to say. it is not loud, but you can tell it is on. the higher the setting the louder it is, but it is not annoyingly loud. sorry i could not be more helpful!
