What a new water heater needs to handle here
Winter nights in Montgomery County average 38°F from December through February, and homes here run their heat from November through March, five months a year. Your water heater is pulling in colder groundwater that whole stretch, working harder to bring it up to temperature.
Power is worth planning around too. Nearly one in five Alabama households went at least a full day without power last year, and the area has logged 34 damaging wind events over the past decade. A gas water heater with a standing pilot keeps making hot water through an outage, while an electric one won't until power is back, though it will start up on its own once it is. Whatever size you choose, it has to meet the federal efficiency minimum set for that tank volume, and the minimum is different for every size.

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?
- Look at the age first. Once a tank water heater gets old, a repair is often just delaying the next breakdown. Water pooling at the base is usually the tank itself failing from the inside, and that's not something to patch. Rusty hot water, a tank that's noisy when it heats, or water that runs lukewarm and won't get hotter no matter how you adjust it are all signs the unit is wearing out rather than just having an off day. If your water heater is in a closet or attic space, a leak like that is worth acting on fast, since a failing tank rarely gives much warning before it lets go.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not on whether tankless is better in general. A tankless unit heats water only when you open a tap, so you're not paying to keep a tank of water hot around the clock, and it won't run out partway through back to back showers the way a tank can. What it won't do is deliver a huge burst of hot water instantly to multiple fixtures at once the way people sometimes expect. If your current tank is near the end of its life anyway, that's a reasonable time to have a contractor walk through whether tankless fits your house and your water use.
- What changes when you install a tankless water heater?
- The biggest change is what feeds it. A tankless unit needs a gas line sized for its higher burner output, or a dedicated electrical circuit if it's electric, and many homes need that line upgraded during install. Venting is different too, since tankless units typically vent through a dedicated pipe rather than sharing a flue the way some tank units do. Because it heats on demand instead of storing hot water, it also needs a minimum flow of water through it to fire up, which is why a single slow-running faucet sometimes won't trigger it. A contractor can look at your gas line, venting, and water pressure and tell you what your house specifically needs to make the switch.
