Water heater replacement cost by type.
Installed prices for Flagstaff, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Flagstaff, water heater replacement costs vary based on unit type and installation complexity. Typical installed prices range from $800–$1,950 for a tank gas unit, $900–$2,200 for tank electric, $1,450–$3,400+ for tankless, and $1,750–$3,900 for a heat pump model. Flagstaff's older homes (median built 1991) often require code updates, and local adoption of the International Plumbing Code means permits are required. The warm winter inlet water and mostly electric heating make heat pump units a strong fit, and the federal 25C tax credit (30% up to $2,000) can offset costs.

Recommended unit for Flagstaff
