When an Ocala water heater starts to go

Published November 13, 2026

If your shower goes cold on a January morning in Ocala, you're not imagining the chill. The official Florida Climate Center record for the Ocala station puts the January average low at 45.6°F. That's milder than a Panhandle winter, but it's plenty cold enough that a dead water heater feels like an emergency.

A lot of the tanks around town are already on a second or third go-round. American Community Survey estimates for 2020–2024 put the median year a housing unit in Ocala was built at 1984. There are 30,387 units in the city. About 28% went up in 2000 or later, and about 14% were built before 1960, including 1,261 from before 1940. In a mid-1980s house, the original heater is long gone. The one sitting in the garage or closet now may have been quiet for years, and most people don't think about it until the water turns rusty, the pilot won't stay lit, or there's a puddle on the floor.

City water here isn't a mystery, but it still matters for the tank. The City of Ocala's 2023 Drinking Water Quality Report says the supply is groundwater from six source wells in the Upper Floridan Aquifer, and that the water is softened, chlorinated, and fluoridated. Softened city water is easier on a heater than raw limestone well water. It does not mean you'll never see scale or sediment. Minerals still settle in the bottom of a tank-style heater. That layer makes the burner or element work harder, and it can pop or rumble when the tank heats up.

The plant that treats that water has been around as long as many of the houses. On the city's Water Treatment Plants page, Water Treatment Plant #1 has been in continuous operation since 1972. The city still describes it as the sole provider of drinking water for more than 69,000 residents, producing an average of 15 million gallons a day, with operators on site around the clock. A second plant is in design, with wells planned in both the Upper and Lower Floridan aquifers. The city says it is expected to be fully operational in 2032, in part to take pressure off the Upper Floridan and help protect Silver Springs.

If you want current finished-water data, use the official report, not a guess. The city's 2023 report is the one we used for the treatment details above. Newer 2024 and 2025 Water Quality Reports are listed on the Compliance Monitoring page. The city does not publish a single hardness number in the materials we relied on, so we are not inventing one here. And if you're on a private well in Marion County instead of city water, the chemistry can be different. Test that water before you blame the heater for every smell or stain.

You can catch a lot of problems without tearing anything apart. Look at the floor or the drain pan for rust or standing water. A slow leak at the tank itself usually means replacement, not a cheap repair. If the hot water looks rusty and the cold side looks fine, the tank or the anode rod is a likely suspect. A rotten-egg smell only on the hot side can be a heater issue. If both sides smell, start with the water supply. Find the manufacture date on the label if you can still read it. Plenty of tank heaters get tired after a decade, but that's a judgment based on condition, not a rule we made up. And leave the temperature-and-pressure relief valve alone. Don't cap it, and don't ignore a discharge pipe that's been dripping.

In a Florida garage, a heater should sit in a drain pan with a line that actually goes somewhere, not into a low spot on the slab. If the current tank has no pan, or the pan is rusted through, that's worth fixing when the unit is replaced, not later. The 2023 city report also noted a taste award that year. Awards don't change how a tank ages, but they do tell you the utility is paying attention to finished-water quality. Inland Marion County still sees tropical rain, wind, and power outages during the June 1 through November 30 Atlantic hurricane season, even when the coast takes the worst surge. A heater that sits through a long outage can throw sediment or trip a breaker when the power comes back. That's a good time to look at the pan again, not a reason to panic about the tank by itself.

When it's time to replace the unit, the right size and the choice between a tank and a tankless heater depend on how the house uses hot water, and on the venting and pan setup in a Florida garage. Those aren't decisions a blog post can make for you. Marion County Building Safety handles permits and inspections for much of the Ocala area. Confirm licensing and permit needs with the contractor and with that office before work starts. You can check a contractor's license with the Florida Department of Business and Professional Regulation.
