Water heater replacement cost by type.
Installed prices for South St. Paul, adjusted for local labor. Larger tanks and code upgrades move the number up.
In South St. Paul, where the median home was built in 1957, many older homes have aging water heaters that need replacement. Local installed prices for a gas tank water heater typically range from $700 to $1,800, while electric tank models run $800 to $1,950. Tankless units cost $1,350 to $3,100+, and heat pump water heaters range from $1,600 to $3,600. Given Minnesota's cold northern climate and cold winter inlet water, gas water heaters are the recommended choice for most homes due to their lower operating cost and faster recovery. Minnesota requires a permit for water heater replacement; homeowners can pull their own permit only if they live in the home. Otherwise, a state-licensed plumbing contractor must handle the work. The 2020 Minnesota Plumbing Code (based on 2018 UPC) also requires an expansion tank on closed systems, which adds to the overall cost.

What Influences Water Heater Replacement Costs in South St. Paul?
The age of your home (median 1957) may require updates to venting, gas lines, or electrical systems, increasing labor. The type of unit—gas, electric, tankless, or heat pump—affects the price range. Permit fees and the need for an expansion tank on closed systems add to costs. Winter inlet water temperature is cold, so gas heaters are more efficient for recovery. If you hire a contractor instead of pulling your own permit, labor costs will be higher.
