Water heater replacement cost by type.
Installed prices for Collegedale, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Collegedale, Tennessee, water heater replacement costs vary by unit type and installation complexity. Typical installed prices range from $700–$1,700 for a tank gas unit, $750–$1,850 for tank electric, $1,250–$3,000+ for tankless, and $1,550–$3,400 for a heat pump model. Because Collegedale is a smaller market (tier 4) with a median home age of 22 years, many homes have original or older water heaters that need replacement. Local permits are required for most replacements under the International Plumbing Code (IPC), and expansion tanks are needed on closed systems. The humid subtropical climate and moderate winter inlet water temperatures make heat pump water heaters a strong fit for energy savings, especially with the federal 25C tax credit covering 30% of cost up to $2,000.
