What a McComb water heater has to deal with
Winters here are mild. Nights average 40°F from December through February, and homes only need heat five months a year, November through March. That's not much strain on a tank by itself.
Power is the bigger question. Statewide, 30% of households went at least 24 hours without power in 2024, and Pike County has seen 34 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water when the power doesn't, worth weighing if you're choosing between gas and electric. Whatever gets installed has to meet the federal minimum efficiency for its size and type, a number that changes with the tank's rated volume rather than one figure for every model.

A heat pump water heater would save about $260 a year to run in Mississippi compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age and how it fails are the two things to watch. Once a tank starts leaking at the seams, that's replacement, not repair, because the tank itself can't be patched. Rusty water from the hot tap, a tank that's noisy or slow to heat, or water pooling at the base are all signs the tank is on its way out. If the pilot won't stay lit or the burner keeps failing after a repair, a contractor will often tell you it's time to replace rather than fix it again.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is bad. Tankless units heat water on demand instead of storing it, so you don't run out partway through back to back showers, and they take up less space than a tank. They also need a strong enough gas line or electrical circuit to run, so switching isn't a straight swap. A contractor has to check what your home can support before recommending it.
- What changes when you install a tankless water heater?
- The biggest change is what feeds the unit. Tankless heaters need more gas flow or a bigger electrical circuit than a tank ever did, so the gas line or wiring often has to be upsized to handle it. Venting is usually different too, since a tankless unit vents differently than a tank model. None of that means it can't be done in your house, it just means a contractor will need to look at what's already there before pricing the job.
