Hydronic heating under concrete definitely has its perks, but honestly, I'd be cautious about recommending it in flood-prone areas. I live in an older home that's seen its fair share of water issues, and I've learned the hard way that anything complicated beneath the floor can turn into a nightmare if flooding happens. Even minor water intrusion can mess with the system, and repairs aren't exactly straightforward—or cheap.
Instead, you might want to consider simpler solutions like insulated subfloor panels or moisture-resistant flooring options that are easier to replace or dry out after flooding. Sure, heated floors feel great, but in areas prone to water damage, simplicity and ease of maintenance usually win out in the long run. Just my two cents from dealing with historic-home headaches...
Wish I'd seen this thread before tackling my basement reno... went with hydronic heating thinking it'd be cozy, and yeah, it was—until that first flood. Repairs cost me a fortune. Simpler flooring would've saved me a ton of headaches (and cash). Lesson learned, I guess.
Hydronic heating can definitely sting your wallet after flooding, but I'd argue it's not always a no-go in flood-prone areas. I've seen some setups where the system was installed with flood mitigation in mind—raised manifolds, waterproof insulation, and easily replaceable flooring sections. Not foolproof, sure, but with proper planning and drainage solutions (like sump pumps or perimeter drains), you can still enjoy the comfort without huge repair bills. It's more about execution than the heating type itself.
We've dealt with flooding a few times in our old place, and one thing I've learned (the hard way) is that flooring choices matter almost as much as what's underneath. Hardwood was a nightmare, but switching to ceramic tile made cleanup way easier. Wondering if anyone's tried engineered vinyl planks with hydronic heating? Seems like it'd be a good compromise—warm floors without the headache of replacing wood every time it floods...
I've installed engineered vinyl planks over hydronic heating a couple times, and honestly, it's a pretty solid combo. Warms up nicely, feels good underfoot, and cleanup after water issues is way less stressful than hardwood. Just make sure you pick a quality brand that's rated for radiant heat—some cheaper ones can warp or gap over time. Learned that lesson the hard way on a client's job...not fun pulling it all back up again.
