Gainesville water heaters run through storms and outages, not cold
Water heaters here work year round. There is no long cold season to point to, just steady demand and whatever the power does. When storms roll through, that's the bigger risk. Alachua County has logged 164 damaging wind events over the past ten years, and 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 on its own once power drops, and most electric water heaters simply wait for power to come back. If yours doesn't, or the water isn't heating right after the lights come back on, that's usually a sign something needs a look, not just a reset.

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 has likely rusted through from the inside and is starting to fail. Water heaters have a steel tank with a glass lining, and once that lining cracks, the steel underneath corrodes until it lets go. A leak from the bottom can also come from a loose drain valve or a fitting that has worked itself loose, which is a much smaller fix. A leaking tank cannot be repaired and needs to be replaced, so it is worth having a contractor look before it lets go all at once.
- 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. A dirty pilot orifice or a draft in the room can also blow the flame out or keep it too weak to hold. If you have relit it a few times and it still will not stay on, the thermocouple or the gas valve behind it needs a look from someone licensed to work on gas appliances.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. The heat exchanger, the igniter, and the flow sensor are the parts that fail most often, and all of them can be replaced. Hard water buildup inside the unit is a common cause of poor performance, and flushing the lines often brings it back to normal. A contractor licensed for gas and water heater work can diagnose which part is causing the trouble.
