Power loss is the risk here, not the cold
Your water heater doesn't work hard against the weather in New Orleans. Winter nights average 46°F, mild enough that the tank isn't cycling constantly to keep up. The bigger threat is what happens when a storm knocks the power out. Orleans Parish has logged 35 damaging wind events over the past ten years, and in 2024 close to half of Louisiana households lost power for 24 hours or more.
A gas water heater with a standing pilot will keep running through an outage. But most tanks now use electronic ignition, and those go dark the moment the power drops. When it comes back, the heater should relight and recover on its own. If it doesn't, or if the water stays cold after an outage, something in the ignition system didn't come back with it.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The tank itself has likely rusted through and is holding water it can't contain anymore. It can also be a loose drain valve or a fitting at the bottom that's failed, which a contractor can sometimes replace without touching the tank. Once the tank itself is leaking, the water heater needs to be replaced, since a rusted tank can't be patched or sealed. A contractor can tell you which one you're dealing with by looking at where the water is coming from.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small part that senses the pilot flame and tells the gas valve to stay open. When it wears out, it can't confirm the flame is lit, so the gas valve shuts off even though the pilot is burning. A dirty pilot orifice or a draft blowing out the flame can cause the same thing. A contractor can test the thermocouple and replace it if that's the problem.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and can be flushed out, and failed igniters, sensors, or fans can be replaced. A contractor can run a diagnostic to find the specific part causing the issue and let you know whether repair or replacement makes more sense for your unit.
