- Heat tape’s a game changer, but I’ve seen folks wrap it over itself or use the wrong kind for plastic pipes—recipe for trouble.
- GFCI is a must, yeah, but I also like to check the tape every fall before plugging it in. Mice love chewing on that stuff.
- For crawlspaces, I’ll sometimes add foam pipe sleeves even with heat tape. Bit of overkill maybe, but it’s saved me more than once when the power went out.
- Not a fan of clamp lights either—too easy for someone to knock them loose or bury them in insulation and forget. That burnt insulation smell lingers forever...
Heat tape’s great—if it’s installed right. I’ve seen more than a few disasters from folks overlapping the tape or using it on PVC that can’t handle the heat. Always check the manufacturer’s label. Some tapes are only rated for metal, and if you put those on plastic, you’re just asking for a split pipe or worse.
GFCI outlets are non-negotiable, especially in crawlspaces or anywhere there’s moisture. I’d add: test the GFCI itself every season, not just the tape. They can fail without warning, and you don’t want to find out after a freeze.
Mice chewing through heat tape is a real headache. I’ve had to patch more than one line after finding gnawed spots. If you’re dealing with rodents, consider running the tape inside a short length of split conduit or even wrapping it with aluminum tape in the worst spots. Not foolproof, but it slows them down.
Foam sleeves over heat tape isn’t overkill in my book, especially in places where you can’t guarantee the power will stay on. Power goes out, and you’ve at least got some insulation buying you time before things freeze solid. I’ve seen folks skip the sleeves because they figure the tape’s enough, but it’s a gamble.
Clamp lights make me nervous too. Too many stories of someone bumping them, or worse, burying them in insulation and starting a fire. If you need a backup heat source, stick to something purpose-built for freeze protection. Anything jury-rigged is just a risk you don’t want.
One last thing: I always recommend labeling breakers and plugs for heat tape circuits. In an emergency, you don’t want to be guessing which switch to flip. Saved me a lot of hassle during late-night calls when the pipes start bursting.

Labeling breakers and plugs is such a simple step, but it really does save your sanity when things go sideways. I’ve been in that late-night scramble, tracing wires with a flashlight, and it’s never fun. I also agree on the clamp lights—seen too many close calls. That said, I’ve had decent luck with foam sleeves even without heat tape in milder climates, but you’re right, it’s a gamble if temps really drop. Your point about testing GFCIs is spot on; they’re not set-and-forget devices. Good reminders all around.

I get why folks label everything, especially when you’ve got a tangle of circuits and mystery outlets. But honestly, I’ve never been super diligent about labeling every single breaker for heat tape. Maybe I’m just lazy, or maybe it’s because my setup’s pretty simple—just a couple of obvious dedicated runs. I can see how it’d be a lifesaver in a bigger house or if you’re dealing with someone else’s wiring job (which can be a real head-scratcher), but for smaller systems, sometimes it feels like overkill. Guess it comes down to how much chaos you’re willing to risk.
On the foam sleeves front—I’m with you about them being fine in milder climates, but I’ve also seen pipes freeze even with insulation if there’s a cold snap and the wind finds its way in. Had a neighbor last year who thought his crawlspace was “warm enough” with just foam, and he ended up with a split copper line anyway. Maybe it’s just my luck, but I lean towards playing it safe with heat tape if there’s even a chance of temps dipping low.
GFCIs are kind of my pet peeve. People forget about them until something stops working. I had one trip quietly in the garage last winter—didn’t notice until the hose bib was frozen solid. Now I test ‘em every couple months, but even then, I sometimes wonder how reliable those little test buttons really are...
Guess what works for one place doesn’t always work everywhere else. Sometimes you gotta learn the hard way—hopefully just once.
I hear you on the GFCIs—had a customer last winter with a frozen kitchen line, and it turned out the outlet for their heat tape had tripped weeks before. They’d never have known if the pipe hadn’t burst. I’m always telling folks to check those outlets, but honestly, I’ve missed a few myself. As for labeling, I used to think it was overkill too, but after spending half a day tracing wires in a 70s ranch with three panels, I’m a convert. Makes me wonder how many “simple” setups are just accidents waiting to happen...
