Water heater installation cost by job.
Installed-labor pricing for Farmington, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation costs in Farmington typically range from $750 to $1,700 for a standard tank unit and $1,700 to $4,200+ for a tankless model. With most homes built around 1967, older plumbing and gas lines may add $275–$950 for new gas line work. Farmington requires a plumbing permit for all replacements, and gas units need a mechanical permit for venting and piping. The cold northern climate means winter inlet water is very cold, so a properly sized gas unit is recommended for reliable performance. The federal 25C tax credit offers 30% back (up to $2,000) on qualifying heat pump water heaters, but gas remains the common choice here.

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.
