Is this really more quiet than the ERP-1000? I'm seeing reviews here that reference the clicking sound but are they referring to this model?

I have the 500 and it is not that loud. You can hear it click every few seconds when it's generating water, but nothing too noticeably loud. It's quieter than people in the room talking.

Don't own a ERP-1000 we have the ERP-500. It does click, but it isn't a problem for us because it is in installed in the garage. Appears to be working well.

It does make some clicking sound but it's not that noticeable to me. If it is loud enough for you and it is bothersome you should really try to get a replacement as it may be defective and will soon fail.

I find it quiet. It's not the CLICK CLICK of a loud mouse but a nice quiet "plunk plunk plunk" sound.

I can hear the clicks on mine if the ambient noise level is low. The clicks are quite subdued. I have 18 of these in service.

I do not remember it making clicking noises when I used it. Maybe you got defective unit?

I have it in a very small office and the only noise you hear is a small clink noise when it starts and stops. otherwise it is very quiet. alot quieter than my large frige at home.

The click clack is audible and unless you HATE that sound I would probably say that you will be satisfied with the sound it makes. If anything, in my opinion, the click clack is on the louder side as opposed to the quieter side.

Not silent and not near silent; key clicks are audible and about the same as my laptop......

It does make a clicking noise. But it's not that loud. You would barely be able to hear it if you were in another room. But no problem right next to it.

I haven't noticed any noise from the unit. I haven't actually been there when the fading light activated the photo cell to cut the unit on, so I don't know whether there might be some "click" at the point -- but I doubt it.

It's very quiet. It's not very big so it doesn't click or move. Consider it "Stealth"

Yes. I barely hear the click. I work using a headset so a loud click would be a problem for me. This Dell works fine for me.

Not between the chroma and original but the stealth version is quite a bit quieter than the click one. (The stealth sounds like browns while the clicky sounds like blues). I prefer the stealth so if you're playing a button masher you're not overwhelmed with clicking sounds.

It does have a fairly distinctive click. If you are using it in a very quiet classroom setting it would be noticeable.

The only sounds you'll ever hear is a low click/ping when it comes back on or turns back off after it reaches the temperature you've set. And when it drops below the set temperature. But it's very low you'll hardly noticed it... Some people have said they've heard that sound besides then, but I haven't heard that. Only the two times I mentioned above. Trust me, you will not be disappointed with your purchase. For how fast it'll heat up the space, and of course how long you'll have it. I've had mine for 7 or 8 years, and it's still performs like day one. Hopefully this helps you determine to buy it. I'm not gonna say not buy, because you really should. I'm just saying...

I have the newest model just delivered today. Nowhere near as noisy as the units in the videos. However mine is sitting on a concrete floor and not on wood.

Yes, it does make noise when you click, because clicking requires a mechanical compression of the click area. (the swipe functions use electrical touch sensing, and it can sense taps, but clicking still requires a physical push down). Its quieter than many mice, but not silent. All mice that use mechanical motion will make some amount of clicking noise. What you want is a "mouse" that has no mechanical motion at all and uses electo-sensing to indicate taps. There's probably something out there if you look around, but note that the only difference between such a non-clicking mouse and a touchpad, is that you can't physically move a touchpad to move the pointer. So maybe you should just get a larger side touchpad instead - there are plenty of those on the market.
