Duval County water heaters run all year, and the power doesn't always stay on
Your water heater works every month here, not just in winter. Storms are the bigger issue. 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 keeps making hot water through an outage since it never needed power to begin with. One with an electronic igniter will not light until power is back, and most units reset on their own once it returns. If yours doesn't, or the pilot won't relight, that points to a problem beyond the outage itself.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The tank itself has likely rusted through and is holding water that seeps out at the seams or the bottom seam. Once a tank starts leaking from the bottom, it means the steel has corroded from the inside, and that damage does not stop or reverse. A leak could also come from a loose drain valve or a fitting near the bottom, which a contractor can check before assuming the tank is the problem. If it is the tank, replacement is the only real fix.
- Why won't the pilot light on my water heater stay lit?
- A pilot that keeps going out is usually a sign the thermocouple is failing. That part sits in the pilot flame and tells the gas valve the pilot is lit. Once it wears out, it reads the flame wrong and shuts the gas off even though the pilot is burning. A dirty pilot tube or a draft in the area can cause the same problem, so a contractor will check both before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. The igniter, the flow sensor, and the heat exchanger are the parts that fail most often, and each can usually be replaced on its own. Mineral buildup inside the unit is common too, especially if the water heater has not been flushed regularly, and clearing that out often solves problems that look like a bigger failure. A contractor can test the unit to find which part is actually causing the issue.
