Totally with you on insulating heat tape—makes sense that it'd spread the warmth better. One extra thing I've found helpful is using foam pipe sleeves over the insulation. They're cheap, easy to cut to size, and seem pretty good at keeping moisture out. Haven't had any dampness issues yet... fingers crossed. Have you tried those? Curious if others have noticed a difference too or if it's just me being overly cautious, haha.

Foam sleeves definitely have their place, especially for moisture control like you mentioned. However, I've noticed that in areas with significant temperature swings or high humidity, foam alone can sometimes trap condensation if not sealed properly at the seams. A quick tip: sealing the joints with waterproof tape or even a bit of silicone caulk can make a noticeable difference in preventing moisture buildup.
On another note, has anyone experimented with reflective foil insulation wraps? I've used them occasionally on exposed pipes in colder basements or crawl spaces. They seem effective at reflecting heat back onto the pipes, but I'm curious if others have found them worthwhile or just redundant when combined with heat tape and foam sleeves...
I've wondered about those reflective wraps too... seems like they'd help, but maybe it's overkill if you've already got foam and heat tape? Honestly, I'm still figuring this stuff out—just hoping my pipes survive winter number one, lol.
Reflective wraps can be useful, but honestly, if you've already got foam insulation and heat tape, you're probably good. I've seen folks go overboard with multiple layers, and while it doesn't hurt, it's usually unnecessary unless you're dealing with extreme cold or pipes exposed to harsh winds. One thing I'd suggest instead is making sure any drafts or gaps around your pipes are sealed up—sometimes that's more effective than adding extra insulation layers.
I've gotta say, sealing drafts is definitely underrated advice. But honestly, even if you've got foam insulation and heat tape, reflective wraps can still make a noticeable difference in certain spots—especially if your pipes run close to exterior walls or through unheated spaces like crawl spaces or garages. I found this out the hard way a couple winters back when the foam alone didn't quite cut it on one particularly chilly night...
Reflective wraps aren't that expensive either, especially compared to dealing with burst pipes (been there, done that—never again). So personally, I'd rather spend a little extra upfront than risk the hassle and cost of repairs. Sure, layering up excessively might be overkill, but adding reflective wrap strategically in vulnerable areas can be worth every penny.
