What a water heater in Alachua County has to handle
Winters here are short and mild, with nights averaging 45°F from December through February. Your water heater will not fight the cold the way one further north does. Most of the demand on it comes from daily use, not the weather.
Power is the bigger question. Across Florida, 38% of households went at least 24 hours without power in 2024, and Alachua County has logged 164 damaging wind events over the past ten years. A new installation is a chance to think about how your water heater handles an outage, and how it comes back on when the power does. Whatever size and type you choose, it will also need to meet the federal minimum efficiency rule for its tank volume, which is set separately for each size and draw pattern rather than as one number for all water heaters.

- How do I know it's time to replace my water heater?
- The clearest sign is a leak coming from the tank itself. That means it is rusting from the inside, and that does not get better or get fixed. Other signs worth acting on are water that never gets as hot as it used to, rusty water coming from the hot side only, or popping and rumbling from sediment built up at the bottom of the tank. A contractor can tell you whether what you are seeing is the tank failing or something smaller, like a heating element or thermostat, that can be repaired instead.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your water heater being old or new. A tankless unit heats water only when you run a tap, so you are not paying to keep a tank of water hot all day, and you get a steady supply instead of running out partway through a shower. Switching usually means changes to the gas line, venting, or electrical to match what the new unit needs. That is more involved than swapping one tank for another, so a contractor will need to look at your home and tell you what the switch would actually involve.
- What changes when you install a tankless water heater?
- The water heater stops being a tank that sits full of hot water and becomes a unit that heats water as it passes through. That usually means new venting sized for the unit, since tankless heaters vent differently than tank models. Gas-fired units often need a larger gas line, because they draw more gas in short bursts than a tank does. Electric models can need a larger electrical circuit for the same reason. A contractor will look at your gas line, venting, and electrical setup and tell you what needs to change for the unit you want.
