Water heater replacement cost by type.
Installed prices for Killeen, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Killeen, TX, water heater replacement costs vary based on unit type, labor, and local code requirements. With most homes built around 1994, many tanks are reaching the end of their 10-15 year lifespan. Typical installed prices range from $850–$2,100 for a gas tank, $950–$2,300 for electric, $1,600–$3,700+ for tankless, and $1,900–$4,200 for a heat pump. Texas law requires a licensed plumber and a permit with inspection for any water heater replacement; DIY installs are not allowed. The humid subtropical climate and moderate winter inlet water make mixed water heating a practical choice. Homeowners should factor in permit fees and potential expansion tank costs if the system is closed.

What drives the cost in Killeen?
