Water heater replacement cost by type.
Installed prices for Hopkinsville, adjusted for local labor. Larger tanks and code upgrades move the number up.
Water heater replacement costs in Hopkinsville, Kentucky, typically range from $650 to $3,300 depending on the type and installation complexity. With a median home age of about 50 years, many homes have older units that may need upgrading to meet current Kentucky State Plumbing Code.

Understanding these factors helps you budget accurately for a replacement that meets code and your needs.

What Affects Your Water Heater Replacement Cost in Hopkinsville
The main price drivers are the unit type and installation complexity. Tank gas models run $650–$1,650, tank electric $750–$1,800, tankless $1,250–$2,900+, and heat pump units $1,500–$3,300.
