What a Meridian winter asks of a new water heater
Winter nights here average 37°F from December through February. Homes need heat from November through March, five months a year, and the water coming into the tank is colder that whole stretch, so a new water heater has to work harder to bring it up to temperature.
Power doesn't always stay on to run it. Mississippi saw 30% of households lose power for 24 hours or more in 2024, and the county has logged 126 damaging wind events and 4 winter storms over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One with electronic ignition won't light until power is back, and an electric tank won't heat either, though it will come back on by itself once power returns.
Whatever gets installed has to clear a federal efficiency minimum, and that minimum 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 the same type can face different minimums depending on their size. A licensed installer will know where the model you're considering needs to land.

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?
- The clearest sign is age combined with trouble. Water heaters wear from the inside as the tank ages, and once that starts, rust-colored water from the hot tap, water pooling at the base, or a popping and rumbling sound during heating all point to a tank that's failing rather than one that needs a small fix. If the tank itself is sound and you're just having a part issue, a contractor can often repair it instead of replacing it. If the tank is leaking, replacement is the only real option since a leaking tank won't seal back up.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out during a long shower or back to back loads of laundry. Switching usually means changes to the gas line, venting, or electrical supply, since a tankless unit draws more power in short bursts than a tank does. A contractor can look at your home's setup and tell you what that switch would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is what feeds the unit. A tankless heater needs a larger gas line or a dedicated electrical circuit than a tank heater does, because it heats water fast rather than keeping a tank warm around the clock. Venting is different too, since tankless units often use a different vent type than a standard tank. The unit itself also mounts to a wall instead of sitting on the floor, which frees up space but means the water lines and gas line have to be run to wherever it's mounted.
