What a new water heater needs to handle here
Breaux Bridge doesn't ask much of a water heater in terms of cold. Winter nights average 44°F from December through February, well above freezing, so the tank isn't fighting frigid groundwater. The bigger question is what happens when the power goes out. Nearly half of Louisiana households lost power for 24 hours or more in 2024, and St. Martin Parish has logged 24 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water straight through an outage. An electric one, or a gas unit with electronic ignition, comes back on by itself once power returns, but not before.
Whatever size and fuel type you choose, federal rules set a minimum efficiency for it, and that minimum depends on the tank's rated volume. A larger tank and a smaller one of the same type don't face the same number. Whoever installs your unit can tell you which minimum applies to the size you need.

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?
- Water pooling at the base of the tank means it's replacing time, not repair time. Rust in the hot water, especially from the hot tap only, points to the tank rusting from the inside. Popping or rumbling sounds mean sediment has built up on the bottom, and once a tank is old enough for that noise, it's usually old enough to consider replacing. If your water heater is old and starting to give you trouble, a new one will cost less to run and less to worry about than the one you have.
- Should I switch to a tankless water heater?
- It depends on what you want from it, not on which one is better. A tankless unit heats water as it flows through rather than storing it, so it doesn't run out during back to back showers the way a tank can. It also takes up less space and tends to last longer than a storage tank. Against that, a tankless unit needs a strong enough gas line or electrical circuit to heat water on demand, and installing one where a tank used to be usually means the gas line, the venting, or the electrical has to change to match. A contractor can look at your house and tell you what that would take here.
- What changes when you install a tankless water heater?
- The gas line, the vent, and sometimes the electrical all have to match what the new unit needs. A tankless heater draws a lot more gas for the moment it's firing than a tank does, so the existing gas line is often too small and needs to be upsized. The venting is different too, since a tankless unit vents differently than a tank and usually needs new pipe run to the outside. Louisiana requires a state licensed contractor for this work, and most cities and counties also require a permit and inspection once it's done. That's normal for a change this size, not a sign anything is wrong.
