Water heater replacement cost by type.
Installed prices for Plymouth, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Plymouth, Minnesota, where the median home was built in 1987, many water heaters are approaching or past their expected lifespan. Replacing a water heater here typically costs between $900 and $4,400, depending on the type and labor. The city follows the 2020 Minnesota Plumbing Code (based on 2018 UPC), which requires a permit for replacement. Homeowners living in their home can pull their own permit, but otherwise a licensed contractor is needed. With cold northern winters and cold inlet water, gas water heaters are the most common and recommended choice for efficient recovery. The federal 25C tax credit offers 30% (up to $2,000) for heat pump models, but gas remains a strong fit for most homes.

Recommended unit for Plymouth
Given Minnesota’s cold northern climate and gas water heating, high-efficiency gas is the sensible default for most Plymouth homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

Water Heater Replacement in Plymouth, explained.
What Affects Water Heater Replacement Cost in Plymouth
In Plymouth, the type of water heater is the main cost driver: tank gas runs $900–$2,200, tank electric $1,000–$2,400, tankless $1,650–$3,900+, and heat pump $2,000–$4,400. Labor and permit fees add to the total. If your home has a closed system, an expansion tank is required by code, which can increase the price. Older homes (like many built in 1987) may need additional updates to meet current code, such as upgrading venting or gas lines, which can raise costs.
Common Water Heater Issues in Plymouth
Sediment Buildup
Hard water and sediment can accumulate at the bottom of the tank, reducing efficiency and causing noise or early failure.
Cold Inlet Water
Plymouth's cold winters mean very cold groundwater, which makes gas water heaters more efficient than electric for recovery.
Permit and Code Compliance
Replacement requires a permit per Minnesota code, and an expansion tank is mandatory on closed systems, which some older homes may lack.
What to Expect During a Water Heater Replacement in Plymouth
A licensed contractor will first obtain the required permit from the city. They will disconnect and remove the old unit, install the new water heater (typically gas in Plymouth), and ensure code compliance, including adding an expansion tank if needed. The job usually takes 3–5 hours. After installation, the contractor will test the system and provide upfront pricing before starting work.
