I used a basic ceramic heater for years and it had a low hum. The Cozy Cove Heater seems a bit louder on high, but maybe it’s just the fan moving more air. Does anyone else notice the noise difference or is it just me? Not a big deal, mostly curious if it’s normal.

Mine got louder on high after a few weeks of use, but it settled back down once I cleaned the vent area. Low is still pretty quiet, high has that fan push sound. Sounds normal to me.

Louder on high is just more air moving, mine does the same.

Mine has a slight rattle at startup that fades after a minute or two. Doesn’t really bug me since I only run it while I’m in the room anyway.

Had a little ceramic cube before this and the Cozy Cove is louder, no question. Mine has a slightly different pitch on high too, more of a whoosh than a hum. I run it on low most evenings and barely notice it over the TV.

I used mine on low overnight for about a week and found it quieter than my old ceramic one. On high it’s a different story, but I rarely need that setting unless the room is really cold. It’s a pleasant little heater overall.

Mine mostly just sounds like moving air, not really a hum.

Fan noise on high is just part of moving that much air, so I don’t think it’s really a defect or anything. But I’d push back on the idea that it’s comparable to an old ceramic. Those little cube heaters usually have a totally different sound, more of a steady hum, while this one has a more noticeable fan push on high. So if you’re expecting the same low hum as before, that’s probably not going to happen. Mine is only annoying if I’m sitting right next to it, otherwise it blends into the background. Curious what room size you’re using it in since that affects how loud it feels.

I’m mostly using it in a small bedroom, roughly 10 by 11, so it’s close enough that the high fan is noticeable. My old ceramic had that steady low hum you’re describing, and this one really does sound more like a fan pushing air. I only ran it on high a couple of times, so I haven’t settled on whether it’s just the extra airflow or a genuinely louder unit.

That room size explains a lot. In a 10 by 11 bedroom you’re close enough that the fan push on high will stand out, especially compared to that old steady hum. I’d try it on low for a night or two and see if that feels closer to what you were used to. High is probably always going to sound more like a fan than a hum in a room that small.

[Pete Sterling]

I’d just run it on low for a while and see if the noise fades into the background. If it still bugs you after a week, that tells you more than any comparison here. Mine took some getting used to, but the high setting is a different beast.

[Susan Keller]

Mine has a bit more of a fan sound than my old one too, but I only really notice it during the first few minutes before the room warms up. After that it kind of blends in with the fridge humming in the next room. So you’re not imagining it, but I don’t think it’s anything out of the ordinary.

The high setting on mine has a more noticeable fan whoosh than the old ceramic thing I had, and I’m in a room about twice the size you mentioned. It’s not a hum, more like air being pushed, so the character of the sound is different even if the volume is similar. I’ve gotten used to it after a few weeks but I can still tell when it kicks on.

[Sophie Nguyen]

I noticed a difference too when I first switched over, and it took me a couple of weeks before my ears just stopped picking it up. Now I only register it when the house is dead quiet at night. Funny how the brain filters out a fan but not the fridge humming.
