How do I know when to replace my old water heater?
Asked by User1234xyz!
Hey everyone! I recently moved into a house and discovered that the hot water tank is a Super Saveall model from the 1980s, which is supposedly the original heater for the home. I found out that the water softener was completely jammed and inactive for some time, which likely caused a lot of calcium and sediment buildup in the heater. The water heater is still functioning and heating water, so I'm conflicted about whether I should wait for it to fail or replace it proactively. Plus, my hydro bills seem unusually high, especially since we don't use many high-energy appliances. Is it worth replacing the heater now, and might I see any real savings on my hydro bill? Thanks for the advice!

Just a heads up—calcium and sediment buildup won't necessarily affect energy use significantly, but it might slow the recovery time of the tank. If it starts leaking, that's a clear sign for a replacement. For a low-cost check, you can replace the heating elements for about $50 and clean out the tank while you're at it. Also, consider getting an insulation blanket for a bit more energy efficiency.

Considering your situation, I highly recommend replacing the water heater now. You're dealing with a nearly 40-year-old unit, high energy bills, and an inactive water softener. The replacement could cost between $2,000 and $3,000, especially with permits and codes to follow, but in the long run, you should save on your bills with a more efficient system. Plus, it's good to know you're taking care of that softener, too!

I wouldn't risk waiting for it to fail since things never seem to break down at a good time! We replaced our water heater after seven years, and I've learned that being proactive is often less of a headache than reacting when something goes wrong.

I’m with everyone else—if your softener hasn’t been working, it might be wise to replace both that and the water heater together. It could help you spot any buildup in the pipes and possibly avoid further issues down the line. I suggest getting several quotes and weighing your options.

CuriousNewbie88: We did end up replacing the softener when we moved in, so at least that part's sorted.
