What a water heater in Dothan is up against
Winters here are mild. Nights average 41°F from December through February, so a water heater in Dothan is not fighting deep cold, and homes only need heat from November through March, five months a year. That is a short heating season compared to much of the country.
Storms are the bigger factor in Houston County. The area has logged 205 damaging wind events over the past ten years, and across Alabama, 18% of households went at least 24 hours without power in 2024. A water heater with a standing pilot lights itself back up once gas is flowing again. One with electronic ignition needs power restored first.
Sizing matters too. Federal efficiency minimums for storage water heaters are not one number. They are set by a formula tied to the tank's rated volume, applied separately across draw patterns, so two tanks of different sizes each have their own minimum to meet.

- How do I know it's time to replace my water heater?
- Look at the age first. Most tanks have a working life, and if yours is old and starting to act up, replacing it before it fails is worth considering. Rust-colored water, a tank that's rusting on the outside, or water pooling underneath are signs it's failing now, not later. If it's making rumbling or popping sounds, sediment has built up on the bottom and the tank is working harder than it should. A water heater that can't keep up, running out of hot water faster than it used to, is also telling you something.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on any rule that says you should. A tankless unit heats water on demand, so you don't run out partway through a shower the way you can with a tank. It also takes up less space and tends to last longer than a storage tank. But it costs more upfront, and a contractor needs to check your home's gas line or electrical capacity before installing one, since tankless units draw more than a standard tank. Whether it's the right move depends on your household's hot water use and what your home can support.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it as it flows through the unit. That means no more standby heat loss from a tank sitting full of hot water all day. It also usually means new venting, since tankless units vent differently than tank models, and often larger gas or electrical connections to handle the higher demand when water is running. Installation is more involved than swapping one tank for another, so a contractor will need to look at your home's setup before pricing the job.
