What Jacksonville asks of a water heater
Winters here are mild. Nights average 46°F from December through February, the only three months homes need heat at all, and a water heater here isn't working against the kind of cold that wears on one further north.
The bigger risk is the power. Duval County has logged 303 damaging wind events over the past ten years, and in 2024, 38% of Florida households lost power for at least 24 hours. A gas water heater with a standing pilot comes back on by itself once power returns. One with electronic ignition needs that power to relight, and so does an electric tank. That's worth weighing when you're choosing a fuel type. Whatever you install, the tank has to meet a federal minimum efficiency set for its rated volume, and that minimum is different for every 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 pooling around the base of the tank, since that means the tank itself is failing and no repair fixes that. Rusty water coming from the hot side, a tank that's making popping or rumbling noises, or water that won't get as hot as it used to are all signs the tank is near the end. Most storage water heaters last a decade or so, and once one starts showing these signs, a contractor can tell you whether it's worth repairing or time to replace it.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not on anything wrong with a tank. A tankless unit heats water as you use it instead of storing it, so you don't run out of hot water during a long shower or back to back loads of laundry. It also takes up much less space than a tank. Whether it makes sense for your house depends on your gas line or electrical service, since tankless units draw more at once than most tanks need, and a contractor can look at your setup and tell you what that involves.
- What changes when you install a tankless water heater?
- The biggest change is that a tankless unit needs more power delivered at once, whether that's gas or electric, because it's heating water on demand instead of keeping a tank warm all day. That often means upgrading the gas line size or adding electrical capacity, depending on the unit. It also mounts on a wall instead of standing on the floor, which frees up the space a tank used to take. A contractor will need to look at your home's gas or electrical service to say what's needed for your specific setup.
