What a water heater here has to deal with
Winter nights in Calcasieu Parish average 44°F from December through February, and homes here only need heat from November through March, five months a year. A new water heater isn't working against real cold for most of the year.
The bigger risk is the power going out. Almost half of Louisiana households lost power for at least 24 hours in 2024, and the parish has logged 77 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep making hot water through an outage since it doesn't rely on electricity to stay lit. One with electronic ignition, or an electric water heater, will sit cold until power comes back, though most start up again on their own once it does.
When you size a new tank, the federal efficiency minimum isn't one number. It's set by a formula tied to the tank's rated volume, applied across four different draw patterns, so two tanks of the same type but different size each have their own minimum to meet.

A heat pump water heater would save about $250 a year to run in Louisiana 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 with a contractor, since older tanks are more likely to be near the end of their life than to be worth repairing. Rusty water, a tank that's damp or rusting on the outside, or water pooling underneath are signs the tank itself is failing, and a leaking tank can't be repaired. If it's still making hot water but running out fast, making popping or rumbling noises, or the pilot won't stay lit, have a contractor look at it before it fails outright and leaves you without hot water.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not just on age or cost. A tankless unit heats water on demand instead of storing it, so it doesn't run out the way a tank can when several showers or loads of laundry happen back to back. It also isn't holding a full tank of hot water around the clock, so it isn't losing heat when nobody's using it. Switching from a tank means changes to the gas line, venting, or electrical circuit depending on the unit, so it's a bigger job than swapping one tank for another, and a contractor can tell you what your home would need.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of taking up floor space, which matters if you're trying to free up a closet or utility room. Gas tankless units usually need a larger gas line and different venting than a tank did, since they draw more gas at the moment they're heating water. Electric tankless units often need a dedicated circuit, and sometimes an upgraded electrical panel to supply it. Because these are changes to gas, venting or wiring, the installation needs a permit and inspection, and a contractor will know what your local building office requires.
