Water heaters here run all year, and outages test the recovery
Pinellas County barely gets a heating season, so a water heater in St. Petersburg spends the year making hot water on demand, not backing up a furnace. That's steady, year-round duty on the tank and its elements or burner.
The county has seen 60 damaging wind events over the past ten years, and across Florida, 38% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps working through an outage. An electric one, or a gas unit with an electric igniter, comes back on by itself once the power returns. Either way, a new installation should account for how the home gets its hot water back after a storm.
The federal minimum efficiency for a storage water heater isn't one number. It's set by a formula based on the tank's rated volume, and it's applied separately across four different draw patterns, so two tanks of different sizes face different minimums even if they're the same type. Whoever installs the new unit needs to size it to the household and match it against the right figure, not a general one.

A heat pump water heater would save about $240 a year to run in Florida compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Check the manufacture date on the label first, since a tank water heater has a limited service life and age is the biggest factor. Rust colored water from the hot tap, water pooling around the base, or rumbling noises as it heats are signs the tank itself is failing rather than just one part. A leak from the tank means replacement, since the tank can't be repaired, only the parts attached to it. If your unit is old and starting to need repairs, replacing it before it fails outright means you get to choose the timing instead of dealing with a flood.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank still works. A tankless unit heats water as it flows through rather than storing it, so you don't run out of hot water partway through back to back showers. It also takes up much less space than a tank, which matters if you're tight on room in a closet or garage. Against that, a tankless unit needs a home with enough gas line capacity or electrical capacity depending on the type, and that can mean changes beyond just swapping the unit. A contractor can look at your gas line or panel and tell you what your house can support.
- What changes when you install a tankless water heater?
- The biggest change is that a tankless unit heats water on demand instead of keeping a tank full and hot around the clock. Gas tankless units typically need a larger gas line than a tank model used, since they draw more fuel in short bursts to heat water quickly. Electric tankless units draw a lot of power at once, which can mean upgrading the circuit or breaker serving it. Venting is different too, since tankless units often use a different vent type than the tank they're replacing. A contractor evaluates your gas line, electrical panel, and venting before installation to know what has to change in your specific house.
