Water heater replacement cost by type.
Installed prices for Billings, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Billings, Montana, water heater replacement costs vary based on unit type and labor. Typical installed prices range from $900–$2,200 for a tank gas unit, $1,000–$2,500 for tank electric, $1,700–$3,900+ for tankless, and $2,000–$4,500 for a heat pump model. Because Billings has cold northern continental winters and cold inlet water, a heat pump water heater is recommended for efficiency, though it carries a higher upfront cost. Montana requires a permit for water heater replacement, and the job must be done by a licensed master plumber or plumbing contractor, with limited homeowner exceptions. The state follows the 2021 Uniform Plumbing Code (UPC), and expansion tanks are required on closed systems.
