What a water heater in Caddo Parish has to handle
Homes here need heat from November through March, five months a year, with winter nights averaging 38°F from December through February. A water heater is working through that cold right alongside the furnace.
Power doesn't always stay on through it. Caddo Parish has seen 7 winter storms and 279 damaging wind events over the past ten years, and statewide, 49% of households went at least 24 hours without power in 2024. A water heater installed here should come back on by itself once power returns, without anyone having to relight it.
The federal minimum efficiency for a new storage water heater isn't one number. It's set by a formula tied to the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes don't meet the same minimum. Whoever installs yours should know which figure applies to the size you're putting in.

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 pooling around the base, rusty water from the hot tap, or a tank that makes a low rumbling sound as it heats. A repair can fix a bad thermostat or heating element, but a leak from the tank itself means the tank is failing, not a part inside it. Once the tank is the problem, replacement is the only real fix.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your current tank failing. A tankless unit heats water as it flows through, so it does not run out partway through back to back showers, and it takes up a fraction of the space a tank does. It costs more to install than a like for like tank swap, and a contractor will need to look at your gas line or electrical circuit and your venting to say what the job actually involves in your house.
- What changes when you install a tankless water heater?
- The unit mounts on a wall instead of standing on the floor, which frees up the space the old tank used. It needs its own venting, sized and routed for that unit, and often a gas line or electrical circuit upgraded to carry what it draws. A permit and inspection apply to this swap the same as they would to a tank replacement, since it is still a water heater installation in the eyes of the local building office.
