What New Orleans asks of a water heater
Winters here are mild, down to 46°F on average from December through February, so your water heater isn't fighting cold groundwater the way one up north would. That's not the main thing to plan around here.
Power is. Louisiana saw 49% of households lose power for 24 hours or more in 2024, and Orleans Parish has logged 35 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water when the lines go down. One that depends on electronic ignition doesn't, until the power is back. Whichever type goes in, it has to meet the federal minimum efficiency for its size and draw pattern, and that minimum is set separately for each tank size, so the right number depends on the one you're installing.

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?
- Look at the age of the tank first. Older tank water heaters get more likely to leak with every year that passes, so if yours has been in service a long time, that alone is a reason to start planning a replacement. Rust-colored water, a tank that's rumbling or popping, or water pooling around the base mean the tank itself is failing, and no repair fixes that. If the tank is newer and just not keeping up, the problem is more likely the thermostat, the heating element, or a gas control valve, and a contractor can tell you which one before you replace anything.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is old. A tankless unit heats water as it flows through instead of storing it, so you don't run out during a long shower or back to back loads of laundry, and it has no tank sitting there to leak. It usually costs more upfront and may need changes to your gas line or venting to install. A contractor can look at your house and tell you what that switch actually involves for your setup.
- 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, since there's no tank to store water. Because it heats water on demand rather than keeping a tank hot, it needs a gas line sized for its higher burner output and its own vent run, and neither of those is usually a drop-in swap from what your old tank used. Most cities and counties, including here, require a permit and an inspection when a water heater is replaced, so that step is part of the job regardless of which type you choose.
