Sanford's water heaters work through storms, not cold
Winters here are mild, so your water heater isn't fighting cold groundwater most of the year the way one up north would. What it does fight is Florida weather. Seminole County has logged 30 damaging wind events over the past ten years, and storms like that knock out power. In 2024, 38% of Florida households lost power for 24 hours or more.
A gas water heater with a standing pilot will keep working through an outage. One with an electronic ignition won't relight until the power is back, and if it doesn't come back on by itself, that's a sign the ignition system needs a look. Electric water heaters simply stop heating until power returns, and after a long outage it can take time to bring a full tank back up to temperature.

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 from the inside and is starting to fail. This usually happens as the metal lining ages and corrosion works its way through the steel, and once a tank leaks like this it will not seal back up. It could also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. If the leak is coming from the tank body, the water heater needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it shuts the gas off even though the flame is lit, so the pilot goes out again soon after you release the knob. A dirty pilot tube or a draft near the burner can cause the same thing. A contractor can test the thermocouple and replace it if that is the issue.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems can be repaired without replacing the whole unit. Common issues are a scaled up heat exchanger, a failed igniter, or a blocked vent, and each of those can be serviced on its own. Hard water buildup inside the unit is one of the more frequent reasons for reduced hot water or error codes. A contractor can run the unit's diagnostics to find out which part is causing the problem.
