What a Cullman water heater has to handle
Winter nights here average 33°F from December through February, and homes run their heat seven months a year, October through April. Cold water coming into the tank in those months means the heater works harder to bring it up to temperature, whatever fuel it runs on.
Cullman County has seen 174 damaging wind events and 5 winter storms over the past ten years, and across Alabama about 18% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep working through an outage. One that relies on electronic ignition or an electric tank will not, and that is worth weighing when you pick a replacement.
New storage water heaters also have to meet a federal minimum efficiency rule, and that minimum is not one number. It is a formula based on the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes from the same product line answer to different minimums. Whoever installs your unit should be able to tell you where the model you're getting falls.

- How do I know it's time to replace my water heater?
- Age is the first thing to check. If yours is old enough that you've stopped counting the years, a repair is often just a delay. Look for water pooling at the base, a tank that's rusting, or water that never gets as hot as it used to. If the heater is old and starting to act up, replacing it before it fails outright means you get to choose the timing instead of dealing with a flooded closet in the middle of winter.
- Should I switch to a tankless water heater?
- It depends on what you want from it. A tankless unit heats water on demand instead of holding a tankful hot all day. It also won't run out partway through a string of showers the way a tank can. The tradeoff shows up in the install, since venting and gas or electric supply requirements are different from a tank setup, so a licensed contractor needs to look at your setup before that switch makes sense.
- What changes when you install a tankless water heater?
- The unit itself is smaller, usually mounted to a wall instead of sitting on the floor, so it frees up space. Venting changes too, since tankless units need venting sized and routed for their exhaust, which isn't always the same path the old tank used. Gas line size or electrical circuit requirements can also change, because tankless units draw more power in short bursts to heat water fast. Any contractor doing the install in Alabama has to hold a state license through the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors, so ask to see it before work starts.
