What a water heater in Leon County has to work with
Winter here is short and mild. Homes only need heat from November through March, and even then, nights average 42°F. Your water heater doesn't face the strain that units up north deal with every winter.
Power is the bigger risk. Wind events hit this area hard, with 473 recorded over the past ten years, and in 2024 close to four in ten Florida households lost power for at least a day. A gas water heater with a standing pilot will keep running through an outage. One with electronic ignition or an electric tank won't fire until power is back, then it comes back on by itself. Whatever you install, it has to meet the federal minimum efficiency for its size and type, since the rules are set separately for each tank volume and draw pattern.

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?
- If it's leaking from the tank itself, that's the clearest sign, and it means replacement, not repair. A tank rusting through won't seal back up. Water that comes out rusty or smells off, or a pilot or igniter that won't stay lit, are other signs worth paying attention to. A unit that's old and also acting up usually isn't worth patching.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not on any rule that says tankless is better. A tankless unit heats water as it flows through, so you're not paying to keep a tank of water hot all day, and you don't run out of hot water the way you can with a tank. Against that, a tankless unit usually costs more to install, especially if your gas line, vent, or electrical setup has to change to fit it. A contractor can look at your current setup and tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets made on demand instead of stored ahead of time. That means no tank taking up space, but it also means the unit needs enough gas flow or electrical capacity to heat water fast, which is more than a standard tank needs at any given moment. Venting requirements are different too, since a tankless unit vents differently than a tank does. A contractor will check your gas line, your electrical panel, and your venting before installing one, since any of those might need work to support it.
