What a water heater in Port St. Lucie has to deal with
Port St. Lucie doesn't ask much of a water heater when it comes to cold. Winter nights average 55°F, and there's really only January where the house needs any heat at all. That's not what wears out a water heater here.
Power is the bigger issue. Statewide, close to 4 in 10 households went at least a day without power in 2024, and St. Lucie County has seen 13 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with an electric ignition won't light until the power is back. That's worth knowing when you're choosing what to install. Whatever size and type you pick, it has to meet the federal minimum efficiency for its category, which is set by a formula based on the tank's rated volume rather than one flat number.

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 at the base of the tank. Once a tank starts leaking, it does not seal back up, and the tank itself cannot be repaired. Rusty or metallic-smelling hot water, a tank making rumbling or popping sounds, or hot water that runs out faster than it used to are also signs the tank is failing inside. If yours is showing any of these and it has been in service a long time, replacing it before it fails is worth planning for. A leaking or failed water heater can also mean sitting without hot water until it is replaced, and with 38% of Florida households losing power for at least 24 hours at some point in 2024, it helps to know a standing pilot gas water heater keeps working without electricity, while most electric and powered gas units will not fire up until power is back.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is old. A tankless unit heats water on demand instead of storing it, so you do not run out of hot water partway through a shower, and it takes up far less space than a tank. It does not heat faster in an absolute sense, it just keeps producing hot water as long as you are running it. Because winters here are mild, with nighttime temperatures averaging around 55°F even at the coldest, a tankless unit here does not have to work as hard as one in a colder climate would to bring water up to temperature. A contractor can walk through your household's hot water use and tell you whether the switch makes sense for your home.
- What changes when you install a tankless water heater?
- The biggest change is what the unit needs around it. A tankless water heater mounts on a wall instead of sitting on the floor, so the closet or utility space that held your old tank opens up. Gas tankless units need a larger gas line than most storage heaters use, and they need a venting setup rated for the higher temperatures they produce, so venting is often replaced rather than reused. Electric tankless units draw a large amount of power at once, which can mean upgrading the circuit that feeds it. Because Florida requires a state license to do this work, any contractor making these changes has to be licensed through the Construction Industry Licensing Board.
