The cost question of upgrading an old electric tank to a heat pump water heater came into focus as a first-time homeowner debated replacing a 13-year-old water heater before it failed.
Energy Star says a family of four may save about $550 per year compared with a standard electric model, but the buyer was on the fence because the old heater was still working.
Here's what to know
A first-time buyer turned to Reddit to ask whether it made more sense to keep roughly $2,500 for other repairs or spend it immediately on a new 13-year-old electric water heater.
The poster said the existing tank had "no visible leaks or rusting" but did not know whether previous owners had ever flushed it or replaced the anode, leaving open the possibility that it might last another year or two.
In the replies, the focus shifted from the heater's age to the damage a leak might cause in that location.
"Unless it's in a spot where you'll have lots of damage if the water heater leaks, I'd just leave it until it goes on its own," a commenter advised.
The original poster replied: "It's in an unfinished basement with concrete floors and a drain nearby. There wouldn't be a lot of damage if it leaked."
A separate commenter leaned on an old family saying of "don't fix what ain't broke." Several others backed that wait-and-watch approach.

More background
The underlying decision was about timing. The original poster said the $2,500 they kept handy for repairs could easily be needed elsewhere.
People in the thread also pointed to warning signs that can show up before a tank gives out. One said to monitor the heater weekly for "water seepage, bulging and corrosion," adding that those are "signs of imminent failure."
The anecdotes also showed how unpredictable water heater lifespans can be. One commenter wrote, "I'm sitting over here with two water heaters that are 33 years old."
One do-it-yourself-minded commenter described a plan to wait for a leak, then replace the unit after it gave out after about 15 years. That person said the job took about 2 1/2 hours once they purchased the new heater.
What can be done?
Because the heater sits in an unfinished basement, some commenters emphasized detection over replacement. The original poster said, "I'm putting a water sensor next to it!"
Suggestions ranged from simple alarms to automatic shutoff options. One commenter recommended a Floodstop device that senses moisture in the pan and automatically stops incoming water, while the original poster said they were also interested in whole-home shutoff systems like Moenflo or Flologic.
The original poster also expressed interest in a heat pump water heater, but was looking to save up for an expensive install.
