Been running the Keilini Heater Pro in my office for a few weeks now and it’s fine for what it is. One thing I’ve been wondering about though: anyone else had issues with it tripping a breaker when you plug it into an older outlet? I know it’s only 800W but my place has old wiring. Just curious if it’s just me or if this thing is sensitive.

Older outlets can be finicky about anything that pulls a steady load, even at 800W. I’ve seen similar things with other heaters in my building. It might not be the heater itself, just the wiring in that particular wall.

Old wiring is probably the real issue here, not the heater itself. I’ve had 800W space heaters trip breakers in older buildings while the same unit worked fine elsewhere. If your outlets are loose or the breaker is already marginal, anything with a steady draw will set it off eventually.

I had mine running daily for a couple months and never had a breaker trip. The office I use it in is pretty new though, so I might just have better wiring. Sounds like the outlet is the problem, not the unit.

Mine has been through a whole winter now and never once tripped anything, even in my drafty old apartment.

I’d lean toward the wiring being the culprit. Older outlets tend to get loose and worn over time, so they don’t hold the plug securely, which causes arcing and heat buildup. I’ve seen that happen with a different 800W heater in a place I used to rent, and swapping outlets fixed the problem. The Keilini itself draws pretty modest power, so I wouldn’t expect it to be the troublemaker.

I’ve got an older house with wiring that’s probably from the 70s, so I get where you’re coming from. My Keilini has never tripped a breaker, but I also stopped using the outlets near the baseboards because those are the ones that tend to be loose. The plug on this thing rotates, which is nice, but it also means the weight of the heater hangs at an angle if the outlet is worn. That’s when I noticed the plug getting warm, not hot, but warmer than I liked. I switched to an outlet that holds the plug tighter and haven’t had a single issue since. I don’t think the heater is overly sensitive, I just think old outlets are the weak link here. If it’s plugging in firmly and still tripping, that’s a different story, but I’d bet on the outlet before blaming the unit.

It’s funny, I actually almost didn’t buy this thing because I read a few complaints about breakers tripping. My place isn’t super old but it’s not new either, so I was a little wary. Ended up getting one anyway because I needed something small for my studio and honestly I’ve had zero issues with it so far. I’ve been using it pretty much every morning for a couple weeks now, plugged into the same outlet, and it’s been fine.

That said, I get why older wiring would be a problem. My parents have a house from the 60s and even a toaster will make the lights flicker over there. I think with any heater it’s just kind of a gamble depending on what circuit you’re on. I’ve had a much bigger space heater trip a breaker at a friend’s place, but the same heater worked fine at mine. It’s almost never the device itself, it’s just how the place is wired.

I’d say if it’s tripping on the same outlet every time, it’s probably that circuit being overloaded or just worn out. Maybe try plugging it into a different room or a different breaker and see if it still happens. If it doesn’t, then you know the heater’s not the problem. But I wouldn’t blame the Keilini right away. Mine’s been solid and I’d probably buy it again if I needed another one.

Old wiring is a beast, honestly. I had a similar thing happen with a tiny 500W heater in my last place, so I get it. Mine’s been fine here, but the outlet it’s in is newer. If it keeps tripping, I’d try another outlet first before blaming the heater.

[Tom 2020]

Only had mine a couple weeks, but the outlet it’s in gets warm to the touch, not the heater itself. If your wiring is old enough that other stuff trips, I’d blame that before the unit. 800W is nothing, so I’d be surprised if this thing is the actual problem.

[Chris Patrick]

I’ve had mine plugged in daily for about two months now and it’s never once tripped anything. If your breaker is popping, I’d look at what else is on that circuit before blaming the heater. Old wiring can be finicky with any load.

[Laura Check]

It’s funny you mention this because I was actually one of the people who almost didn’t buy it after reading those same complaints. My place is a rental and the outlets are pretty hit or miss, so I figured I’d be dealing with this exact issue. But after using mine for about a month now, I’ve had zero problems with breakers tripping. The outlet does get a little warm if I leave it running all day, but that’s normal for any heater in my experience.

What I did notice is that it really depends on which outlet I use. The one in my kitchen is fine, but the one in my bedroom is on a circuit with a bunch of other stuff, and I can tell it’s working harder when the microwave or the TV is on at the same time. I just started plugging it into a different outlet and it’s been fine. I’m not saying the heater is perfect, but I do think old wiring makes a big difference. My last apartment had knob and tube and I couldn’t run anything without blowing a fuse, so I get the frustration.

I’d say if yours is tripping, it’s probably not the heater itself but just the circuit it’s on. Maybe try a different outlet that’s not shared with as many appliances and see if that changes anything.

[Lisa Hydrow]

I’ve had mine since December and not a single trip, but I keep it on the same circuit as basically nothing else. My brother tried his in his garage with a mini fridge and a TV on the same line and it popped the breaker the first day. That little 800W adds up fast when other stuff is pulling.

[Mike89]

I’ve got a couple of these heaters in my house and neither one has ever tripped a breaker. I did notice the plug gets a little warm but nothing crazy. If your place has old wiring, that’s probably the real issue, not the heater itself. I’ve run mine on a circuit with a TV and a computer and it’s been fine.

[Nina Ray]

I actually think the breaker tripping might have more to do with what else is on that circuit than the heater itself. I have one in my bedroom and one in the little sunroom off the kitchen, and they’ve both been going since February without a single issue. But I also learned the hard way in my last apartment that old wiring does not mess around.

That place was a 1920s building and I had a tiny little oil radiator that was way less powerful than this heater. It would trip the breaker almost every night. I was convinced the radiator was defective until my landlord came out and told me the whole bedroom and hallway were on the same circuit as the bathroom, and if the bathroom fan was running while I had the radiator on, that was enough to push it over. Soon as I started unplugging stuff, it never happened again.

So with the Keilini, I honestly think the rotating plug adds a layer of weirdness because if the outlet is loose or the connection isn’t great, it can pull more current than it should. But I’ve had mine on a dedicated enough circuit with nothing else drawing much and it’s been totally fine. I would probably suspect the outlet itself first, especially in an older place.
