What a water heater in Thibodaux has to deal with
Winters here are mild. Nights average 47°F from December through February, and homes only need heat four months out of the year. A water heater in Lafourche Parish is not fighting deep cold the way one further north would, but it still has to be ready to work through the wind and power loss that come with this area's storm season.
Almost half of Louisiana households lost power for 24 hours or more in 2024, and the parish has logged 16 damaging wind events over the past ten years. A gas water heater with a standing pilot will come back on with no help once power returns. One with electronic ignition needs power to relight, so it's worth knowing which kind is going into the house. Whatever model gets installed, it has to meet the federal efficiency minimum for its size and type, which is set separately for each tank volume rather than as one flat number.

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?
- The clearest sign is water that isn't as hot as it used to be, or that runs out faster than it once did. Rust colored water from the hot tap, a tank that's rusting on the outside, or water pooling underneath are all signs the tank itself is failing. Popping or rumbling noises usually mean sediment has built up at the bottom of the tank, which makes the heater work harder to do the same job. If your water heater is showing any of these signs, it's worth having 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 on any rule that says one is better. A tankless unit heats water on demand instead of storing it, so you don't run out partway through a shower if someone else just used hot water. It also doesn't sit there keeping a tank of water hot all day when nobody's using it. The tradeoff is that installing one often means changes to the gas line, venting, or electrical supply to the house, since tankless units have different requirements than a storage tank. A contractor can look at your current setup and tell you what installing one would actually involve in your house.
- What changes when you install a tankless water heater?
- The biggest change is that a tankless unit needs a bigger gas line or a dedicated electrical circuit than a tank ever did, because it has to heat water fast rather than gradually over time. It also needs different venting, since it's not just holding warm water but firing up each time a hot tap opens. Because of this, installing one is more than swapping the old unit out for a new one in the same spot. The job still needs a permit from the local building office and an inspection once it's done, the same as any other water heater installation.
