Thinking about getting a Coolizi Coolzy for my living room but my place is pretty drafty in winter. Does it actually keep up or would I just be wasting electricity? Not expecting it to heat the whole house, just want to know if it’s worth it for one room that loses heat fast.

Mine barely kept up in a leaky room.

I keep mine in a back bedroom that gets cold and it does fine as long as I shut the door. Whole point is heating the space you’re actually in. Wouldn’t expect it to fight a room with a window cracked open or anything.

Drafty rooms are exactly where these things struggle. I had one in an old place with bad windows and it ran constantly just to hold a temperature. It’s not that it did nothing, but the cold always won eventually.

I actually think drafty rooms get a bad rap with these things. Everyone says they can’t keep up, but my experience has been the opposite. I’ve got an old rental with windows that might as well be open in January, and my Coolzy still gets my living room to a comfortable temp in about 20 minutes if I start it before I settle in. It doesn’t hold the temp perfectly if it’s really windy out, but it’s not running nonstop either. I think people expect it to work like central heat and then act surprised when it doesn’t. For one room where you’re actually sitting, it’s fine. My electric bill went up maybe 15 bucks last winter using it most evenings. That seemed reasonable to me. The trick is just not trying to heat a space with the door open to the rest of the house.

Worth it if you shut the door behind you.

I’d say yes for one room, especially if you’re not trying to heat the whole place. Mine warms up my living room fine even with old windows, as long as I give it a bit to get going. It’s not magic but it does the job.

[Taylor R.]

Mine didn’t keep up in a drafty room either, so I don’t buy the “just shut the door” fix. A closed door doesn’t stop cold air coming through old windows. I ended up using it as a spot heater near my chair instead of expecting the whole room to warm evenly.

Mine actually did fine in a drafty front room, which surprised me after reading all the doom and gloom. It ran more than usual, sure, but the room stayed comfortable enough. I left it going most evenings that first winter and didn’t notice a scary jump in the bill.

[Mike Reynolds]

Is it worth it? Depends what you mean. I had one in a drafty rental with original windows that leaked like a sieve, and yeah it warmed the room, but it never felt like it got ahead. It just ran and ran, and the second I walked near the window I could feel the cold pouring in. My electric bill that winter was not cute. So if your version of “worth it” means the room gets noticeably warmer while you’re sitting in it, fine. If it means the thing actually keeps up and shuts off like a normal heater, probably not. You’re basically paying to fight the draft. Fix the draft first and it’ll feel like a different machine.

I went back and forth on this for a while before I actually bought one, and my view shifted a fair bit after living with it. Originally I figured any small unit like this was going to be a waste in a room that leaks heat, because that’s the usual line you hear. I mostly wanted it for the warmer months anyway, so the heating side was almost an afterthought for me.

What actually changed my mind was using it through a couple of cold snaps. It didn’t magically fix the room, but it kept the space around where I was sitting noticeably warmer, which was really all I wanted. It ran a lot during those days though. That part surprised me a little. It’s not the kind of thing you switch on for twenty minutes and forget about.

Where I’d push back on some of the confident takes here is the idea that it either works or it doesn’t in a drafty room. In my case it depended heavily on where I put it. Near a cold wall or right by a window and it felt pointless. Moved a few feet toward the middle of the room and it made a real difference. Same unit, same day.

So I wouldn’t call it a waste of electricity, but I also wouldn’t expect it to feel like proper heating. It’s more of a keep the chill off situation for me.

[Brooky]

I run mine in a drafty back room most evenings and it handles it fine. It kicks on more often than in my bedroom, but the room still gets comfortable. Electricity went up a bit, nothing wild. Worth it if you just want that one room livable.

[Alex Foster]

If the room is losing heat that fast, I think you’re mostly paying to fight the outdoors. It’ll take the edge off, but a drafty living room is kind of the worst case for these things.

[pixelnomad]

I’d rather put that money toward sealing the windows first. Drafts make any portable unit look bad, and fixing the leak helps year round.

[northshore]

The draft is going to matter way more than which unit you pick, that part is just true. But since you already know the room is leaky and you’re not expecting miracles, I’d say go for it. I’ve had mine since last fall and the thing that surprised me is how little it actually runs once the room hits the temp I set. It’s not blasting constantly like I assumed it would. It cycles. My old space heater just sat there eating power nonstop, this one actually backs off.

The bigger annoyance for me was placement. I had it tucked in a corner at first because that’s where the outlet was and it felt like it was fighting itself. Moved it more into the open and it made a noticeable difference in how fast the room warmed up. Sounds dumb but it took me a couple weeks to bother trying it.

For a living room you actually sit in every evening, I think it’s fine. It’s not going to fix a room that’s bleeding heat out of every seam, nothing portable will, but if you just want the couch area comfortable while you watch TV, it does that. Mine’s been running most nights since November and I haven’t regretted it. Electric bill went up but not in a way that made me wince.

[Tina Bell]

Drafty rooms eat those things alive.

[Jake Paul]

Mine does fine in a room with two old windows that whistle when the wind picks up, so a draft alone isn’t a dealbreaker. The part nobody mentions is how you run it. I tried blasting it on high and just burned through electricity for nothing, the room never really settled. Leaving it on a lower setting for longer works better, it sort of keeps pace instead of fighting the cold. That said, the first winter I had it I was checking the meter constantly because I assumed it was bleeding money. It wasn’t as bad as I expected, but it’s not free either. If your living room is where you actually sit all evening, paying for it makes sense. If you’re heating a space you walk through twice a day, you’re just feeding the drafts.

If it were me, I’d get the Coolzy but treat it as a spot heater rather than something that’ll fix the whole living room. I used one in my last apartment, which had a giant single-pane window in the front room, and the heat mode did fine if I was sitting within maybe six or eight feet of it. Walk to the other side of the room and you notice the difference fast. It kept my little couch area comfortable while I watched TV, but the rest of the room stayed cool.

What I’d actually do is set it up near where you sit most, close the doors to the rest of the house, and run it on a lower setting instead of blasting it. That way it cycles less and you’re not watching the meter spin. For one room that loses heat, I think it’s worth trying if you mainly want to be warm in one spot. If you want the whole living room to feel toasty from corner to corner, that’s probably asking too much.

[Gary Scott]

If you’re just trying to keep one room from feeling like a freezer, it’ll do that. I ran mine in a leaky back room all last winter and it kept the chill off, but the second I walked two feet away it was like the thing never existed. Electric bill wasn’t pretty either.

[Mike Hall]

I ended up grabbing one anyway and it’s been fine in my drafty living room, keeps it comfortable enough while I’m in there. Doesn’t fight the cold when the wind really gets going though. Good enough for me, I wasn’t expecting miracles.
