Water heater replacement cost by type.
Installed prices for Dunedin, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Dunedin, Florida, replacing a water heater typically costs between $700 and $3,600, depending on the type and complexity. With many homes built around 1976, older units may require updates to meet current Florida Building Code, including a drip pan with drain for units in living spaces and a TPR valve discharging within 6 inches of the floor. The warm humid subtropical climate means inlet water is warm year-round, making heat pump water heaters a strong fit—they qualify for a federal 25C tax credit of 30% up to $2,000. Permits are required for replacement, and an expansion tank is needed if your system has a backflow preventer or pressure-reducing valve.
