Water heater replacement cost by type.
Installed prices for Gainesville, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Gainesville, Florida, where the median home was built in 1982 and homeownership is 33.2%, water heater replacement is a common upgrade. Local installed pricing for tank gas units ranges from $800 to $2,000, tank electric $900–$2,200, tankless $1,500–$3,500+, and heat pump models $1,800–$4,000. Given the humid subtropical climate and warm winter inlet water, heat pump water heaters are a strong fit, especially with the federal 25C tax credit covering 30% of cost up to $2,000. Permits are required under the Florida Building Code, and an expansion tank is needed on closed systems. Drip pans with drains are mandatory for units in or above living spaces, and TPR valves must discharge within 6 inches of the floor.

What Affects Water Heater Replacement Cost in Gainesville

Older homes (median built 1982) may require updates to meet current code, like adding an expansion tank or drip pan. Permits add $50–$200. Heat pump models cost more upfront but qualify for the federal tax credit. Access difficulty and removal of old units also influence the final price.

What to Expect During Replacement

For closed systems, an expansion tank will be installed. The job typically takes 3–6 hours.
