What a water heater in Etowah County has to deal with
Winter nights here average 34°F from December through February, and homes need heat from November through March. The tank isn't fighting the kind of cold that cracks pipes further north, but the bigger risk is the power staying on. Almost one in five Alabama households went at least 24 hours without power in 2024, and Etowah County has logged 71 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition, or an electric unit, will not, though it should come back on by itself once power returns.
Whatever size and type goes in, it has to meet the federal minimum efficiency for that tank. That minimum isn't one number. It's set by a formula tied to the tank's rated volume, applied separately across four draw patterns, so two water heaters of the same type in different sizes can face different minimums.

A heat pump water heater would save about $310 a year to run in Alabama compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age is the first thing to check. Tank water heaters have a limited service life, and once yours is old, a repair may only buy a little time before something else fails. Rusty water, a tank that's damp or wet around the base, or a unit that can't keep up with hot water anymore are all signs the tank itself is wearing out, not just a part inside it. If the tank is leaking, that's not a repair, that's a replacement, since a tank doesn't get fixed once it's cracked.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on your old tank failing. A tankless unit heats water as it flows through instead of storing it, so you don't run out of hot water partway through a shower, but it also means the unit depends on power to run, gas or electric. With 18% of Alabama households going at least 24 hours without power last year, and this county seeing 71 damaging wind events over the past ten years, that's worth thinking about before you decide. A contractor can walk through what your household actually uses and price out both options for your house.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, which means no more running out partway through back to back showers. It also changes what the unit needs to run. Gas tankless units need proper venting sized for the unit, and electric ones often need more electrical capacity than a tank ever did. The install itself usually means new venting, gas line, or wiring work, not just swapping one box for another, so a contractor needs to look at your gas line, electrical panel, and where the unit will sit before pricing the job.
