"Has anyone noticed fewer problems in areas with softer water? Might be worth checking before completely ruling out tankless setups..."
Funny you mention that—I had a similar experience a few years back. Had a rental property in an area notorious for hard water, and the tankless heater there was constantly giving me headaches. I was convinced it was just a faulty unit or bad luck until I installed the exact same model at another place across town, where the water was noticeably softer. Night and day difference. The second one ran smoothly for years without a hiccup.
Made me realize water quality plays a bigger role than I'd thought. Not saying tankless is always the answer—I've had traditional tanks last forever too—but it's definitely something to factor in before making a decision. Maybe testing your water hardness first could save you some trouble down the line...
Interesting points on the water hardness issue. I've always been skeptical about tankless setups—not because they're inherently bad, but more because I've seen a few friends run into unexpected maintenance headaches. But I hadn't really considered how much water quality might factor in.
Here's my situation:
- Traditional tank heater, about 12 years old now, starting to show rust around the bottom and occasionally giving me rusty-colored water.
- Water here is pretty hard—lots of mineral buildup on faucets and showerheads.
- Been debating whether to replace with another traditional heater or try tankless, but now I'm wondering if I should tackle water softening first...
I mean, if hard water messes up tankless heaters quicker, wouldn't it also cause more rust and corrosion in tank heaters too? Maybe it's just less obvious because we expect tanks to eventually rust out anyway.
Also curious—has anyone installed a whole-house softener specifically to prolong water heater life (tank or tankless)? Did it actually help noticeably with corrosion issues or maintenance hassles? I'm usually skeptical about adding extra equipment unless there's a clear benefit, but if it genuinely reduces problems long-term, might be worth considering...
You're definitely onto something with the water softener idea. I installed one about three years ago, and honestly, the difference in buildup and corrosion has been noticeable. Might be worth considering before investing in a new heater...
"Might be worth considering before investing in a new heater..."
Fair point, but wouldn't a softener mainly prevent future buildup rather than fix existing rust issues? If the heater's already rusty inside, seems like it might just delay the inevitable replacement... thoughts?
"Fair point, but wouldn't a softener mainly prevent future buildup rather than fix existing rust issues?"
Exactly right. A water softener is great for preventing mineral deposits and prolonging heater life, but it won't do much if you've already got significant rust inside the tank. Once rust sets in, you're basically on borrowed time. I've seen folks try flushing their tanks repeatedly or using rust inhibitors, but honestly, that's usually just kicking the can down the road.
If your heater's already rusty inside, replacement is probably your best bet. Rust weakens the tank walls over time, and you definitely don't want to risk a leak or worse—a flooded basement (been there, done that... not fun). If budget allows, I'd bite the bullet now rather than gamble on temporary fixes. Just my two cents from experience—better safe than soggy floors!
