    Default Should I repair or replace water heaters?

    I have two State water heaters that are 14 years old. Water temperature is now warm rather than hot. I replaced expansion tank a year ago. Should we repair or replace water heaters?

    Gas or electric? Usually, I only recommend replacing when they start to leak. Your FIRST task is to find out why the water is only warm, otherwise, you may replace the heaters and find out you STILL have the same problem if it is functional problem.

    The water heaters are gas.

    My last State gas water heater lasted for 10 years before springing a leak. I would have liked to cut it open to see the innards as I suspect it had quite a build-up inside. The installer that took it out said it weighed a lot more than when it was new.

    I would not repair a 14 year old gas heater, figuring that the build-up inside would significantly reduce efficiency and capacity.

    In the USA, (nearly) all residential WH are now required to have protection from igniting vapors from volatile liquids that may be in the area. These have been problematic for some companies. They also generally mean that a new WH of the same volume will likely be taller, since the burner design is different to prevent that ignition. I'd look at Rheem or Bradford White. Some of their models qualify for Energy Star efficiencies, and may get you a rebate from your local utility company - well worth asking.
