Went tankless about two years ago myself and mostly agree—it's been solid. But yeah, there were some hiccups early on. Had to upgrade our gas line to handle the demand safely, which added unexpected cost. Also noticed slight temp fluctuations if multiple taps run at once. Overall happy, but it's definitely not a plug-and-play solution for everyone...
Had a similar experience myself when I switched one of my rentals to tankless about three years back. Honestly, didn't expect the gas line upgrade either—caught me off guard and added a chunk to the budget. Also noticed tenants mentioning the temp fluctuations when running laundry and showers simultaneously. Not a huge deal, but something to keep in mind if you've got a busy household.
On the flip side, maintenance has been way easier since then. No more panicked calls about rusty water or leaks flooding the basement at 2 AM... which is always a plus. Still, I wouldn't say tankless is the right move for every property. Older buildings especially can throw curveballs your way with unexpected upgrades needed to handle the load. If you're dealing with rust issues already though, might be worth biting the bullet now rather than patching things up repeatedly down the road.
Had a similar surprise when my uncle switched to tankless—he didn't realize the electrical panel needed upgrading too. Ended up costing him double what he planned. Curious if anyone else ran into unexpected electrical issues instead of gas line headaches?
Ran into something similar last year when helping a friend install a tankless electric heater. He assumed his existing wiring would handle it, but turns out the unit required two dedicated circuits—his panel was already maxed out. Ended up needing a subpanel, extra breakers, and new wiring runs... definitely not the quick weekend job we expected. Tankless is great in theory, but always worth double-checking electrical specs beforehand to avoid surprises.

Good point, but honestly, electric tankless isn't always the best solution, especially if your electrical setup is older or limited. Sometimes a high-efficiency tank heater can be simpler and more cost-effective overall... fewer headaches with wiring upgrades.
