What a Houma water heater has to deal with
Winters here are mild, down to 48°F on a December night, so your water heater isn't fighting the cold the way one further north would. It only needs real help from November through February, four months a year.
The bigger risk is the power. Nearly half of Louisiana households lost power for at least 24 hours in 2024, and the parish has logged 28 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electric ignition, or an electric tank, won't heat water until the power comes back.
The federal minimum efficiency for a new storage water heater isn't one number. It's a formula based on the tank's rated volume, applied differently across four draw patterns, so two tanks of the same type can face different minimums depending on size. Getting this right means sizing the new unit to what the household actually draws, not just matching what was there before.

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?
- Watch for water around the base of the tank. That is usually the tank itself failing, not a loose fitting, and once a tank starts leaking it does not stop or get better. Rusty water, a tank making rumbling or popping sounds, or hot water that runs out faster than it used to are also signs the tank is on its way out. Most storage water heaters last a decade or so, and if yours is getting up there in age along with any of these signs, it makes sense to plan a replacement before it fails on its own.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water as you use it instead of keeping a tank full and hot around the clock, so you do not run out of hot water partway through a shower, and it takes up much less space than a tank. It also means changes to the gas line, venting or electrical supply, since tankless units draw more of each at once than a tank does. A contractor can look at your home and tell you what that switch actually involves.
- What changes when you install a tankless water heater?
- The unit itself is smaller and mounts on a wall instead of standing on the floor, which frees up space where the old tank sat. Behind that, the gas line, venting and sometimes the electrical circuit usually need to be upsized to match what the tankless unit needs to fire at full output. The venting is different too, since tankless units vent differently than a tank does. Because of these changes, this is a job for a licensed contractor, and in most areas it needs a permit and an inspection once the work is done.
