What a new water heater needs to handle here
Morgan City winters are mild. Nights average 47°F from December through February, and homes here only need heat from November through March, five months a year. A water heater isn't working against much cold.
Power is the bigger question. Nearly half of Louisiana households went at least 24 hours without power in 2024, and St. Mary Parish has recorded 16 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage since it doesn't depend on electricity to stay lit. One with electronic ignition, or an electric tank, will sit cold until the power is back, though most start back up on their own once it is. Worth knowing which kind 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?
- The clearest sign is water that won't stay hot or runs out fast, especially if that's new. Rust colored water, a tank that's rusting on the outside, or water pooling underneath are signs the tank itself is failing, and a leaking tank won't get better on its own. Popping or rumbling sounds mean sediment has built up on the bottom, which makes the unit work harder to heat the same amount of water. If yours is showing any of these signs, it's worth having a contractor look at it before it fails outright.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not just on your old tank failing. A tankless unit heats water as you use it instead of storing it, so you don't run out during a long shower or back to back loads of laundry. It also has no tank to rust through or build up sediment, which is the usual way a storage heater fails. Against that, it costs more to install and usually needs a contractor to check that your gas line or electrical circuit can handle it, so it's a real decision, not an automatic upgrade.
- What changes when you install a tankless water heater?
- The unit itself changes first. A tankless heater is smaller and mounts on a wall instead of taking up floor space, and it has no tank to leak or fail from sediment. Behind the wall, the gas line, venting, or electrical circuit often needs to be upsized to give the unit enough fuel or power to heat water on demand, which is why this isn't a straight swap. The job also needs a permit from the local building office and an inspection once it's done, so a licensed contractor will handle both the install and the paperwork.
