Water heater replacement cost by type.
Installed prices for Fairmont, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Fairmont, Minnesota, water heater replacement costs typically range from $650 to $1,600 for a tank gas unit, $700 to $1,750 for tank electric, $1,200 to $2,800+ for tankless, and $1,450 to $3,200 for a heat pump model. With a median home built in 1962 and cold northern winters, older homes often have undersized or aging equipment, and the cold inlet water increases heating demand. Labor includes permit fees (required by the 2020 Minnesota Plumbing Code), and an expansion tank is needed on closed systems. Most Fairmont homes use gas, making a gas water heater a practical choice. Homeowners who live in their home can pull their own permit, but a licensed contractor is required for rental or non-owner-occupied properties.

Recommended unit for Fairmont
Given Minnesota’s cold northern climate and gas water heating, high-efficiency gas is the sensible default for most Fairmont 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.
