What a water heater in Marion County has to handle
Winters here are mild. Nights average 47°F from December through February, and that is the only stretch of the year when a water heater is working against real cold. The rest of the year it has an easier job.
Power is the bigger question. In 2024, 38 percent of Florida households lost power for at least 24 hours, and Marion County has recorded 156 damaging wind events over the past ten years. A storage tank heater comes back on by itself once power returns. A tankless unit needs power to fire at all, storm or no storm. Whoever installs your water heater also has to meet a federal efficiency minimum that is not one number for every tank. It is a formula based on the tank's rated volume, so the minimum for your unit depends on its size.

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?
- The clearest sign is water on the floor around the tank, since that means it's leaking and won't stop. Rusty or metallic-smelling hot water is another sign, especially from a tank that's been in service ten years or more. If it's making a low rumbling sound, sediment has built up in the bottom of the tank and it's working harder than it should. A water heater that can't keep up anymore, running cold partway through a shower it used to handle fine, is telling you the tank or the heating element is failing. Any one of these on its own is worth a look. A leaking tank should be replaced, not repaired.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water only when you're using it, so there's no standby tank losing heat around the clock. It also takes up a fraction of the space a tank does, which matters if the water heater is in a closet or a tight utility spot. The tradeoff is the install itself. Gas tankless units often need a larger gas line and a different vent than the tank they're replacing, and electric tankless units can call for more amperage than the panel currently has. A contractor can look at the gas line, the vent, and the electrical panel and tell you what the switch actually involves in your house.
- What changes when you install a tankless water heater?
- The unit itself is the biggest change. It mounts on the wall instead of standing on the floor, so it frees up the space the tank used to occupy. Gas models usually need a bigger gas line than a tank version did, because they draw more fuel to heat water on demand, and the vent pipe is often a different type and size. Electric tankless units draw a large amount of power for a short burst, which can mean upgrading the circuit or even the panel. None of this makes it a bad choice, it just means the installation is more involved than swapping one tank for another, and a contractor will need to check the gas line, vent, and electrical setup before quoting the job.
