What a new water heater needs to handle in Prattville
Winter nights here average 37°F from December through February, cold enough that incoming water runs cold and the tank has to work to bring it up to temperature, but not cold enough to demand anything special from the unit itself.
The bigger factor is power. Storm data for this area shows 34 damaging wind events over the past ten years, and statewide, 18% of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition, gas or electric, will not heat water until the power comes back, though most start up on their own once it does. Worth asking about when you pick a replacement.
Any new storage water heater installed has to meet the federal minimum efficiency for its type and size. That minimum is not one number. It is set by a formula tied to the tank's rated volume, applied differently across four draw patterns, so two tanks of the same type can face different minimums depending on their size.

- How do I know it's time to replace my water heater?
- Look at the age first. Water heaters have a working lifespan, and once yours is well past it, a repair is just delaying the next breakdown. Rust-colored water, a tank that's rusting on the outside, or water pooling underneath are signs the tank itself is failing, and a tank cannot be repaired once it's leaking. If it's still making hot water but running out fast or taking longer to recover than it used to, that's usually the heating element or a sign of heavy sediment buildup at the bottom of the tank. A contractor can check the age off the serial number and tell you whether it's worth repairing or time to replace it.
- 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 only when you open a hot tap, so you don't run out during a long shower or back to back loads of laundry, and it doesn't sit there keeping a tank of water hot all day. Against that, a tankless unit costs more to install than a like for like tank replacement, and if your home's gas line or electrical service wasn't sized for one, that work adds to the job. A contractor can look at what you have now and tell you what switching would actually involve in 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 the unit needs enough gas supply or electrical capacity to heat water fast the moment a tap opens. Many homes need a larger gas line, a dedicated circuit, or new venting to meet that demand, since a tankless unit's requirements are different from a tank's. You also gain space, since a tankless unit mounts on a wall instead of taking up floor space. A contractor can walk through your home's gas, electrical, and venting to tell you exactly what the switch would require.
