Water heater installation cost by job.
Installed-labor pricing for Trenton, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Trenton, Michigan, where the median home was built in 1960, many homeowners face water heater replacements. A standard tank installation typically runs $700–$1,550, while tankless units cost $1,550–$3,900 or more, plus $250–$850 for a new gas line. The cold northern climate and cold winter inlet water make gas water heaters a recommended choice for reliable performance. Michigan requires a plumbing permit and inspection for any water heater replacement, and gas units also need a mechanical permit for gas piping and venting. An expansion tank is required on closed systems with a PRV, check valve, or backflow preventer. The federal 25C tax credit offers 30% up to $2,000 for qualifying heat pump water heaters, but gas units remain common due to lower upfront costs and local fuel availability.
