Water heater replacement cost by type.
Installed prices for Williston, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Williston, North Dakota, replacing a water heater involves costs that reflect the local climate, building codes, and market conditions. With a median home age of about 23 years, many homes are due for a replacement. Typical installed prices range from $750–$1,900 for a tank gas unit, $850–$2,100 for tank electric, $1,450–$3,400+ for tankless, and $1,750–$3,800 for a heat pump. Because Williston has cold northern continental winters with very cold inlet water, gas-fired heaters are often recommended for their faster recovery and lower operating cost. A permit is required, and work must be performed by a licensed plumber, which adds to labor costs. The federal 25C tax credit (30% up to $2,000) applies for qualifying heat pump water heaters, but no statewide rebates were found.
