Water heater installation cost by job.
Installed-labor pricing for Maryville, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Maryville typically costs between $750 and $1,700 for a standard tank unit, while tankless installations range from $1,700 to $4,200 or more. With a median home age of 41 years, many homes may need upgrades like a new gas line ($275–$950) or an expansion tank, which is required on closed systems under Tennessee's adoption of the 2021 International Plumbing Code. The humid subtropical climate and moderate winter inlet water temperatures make heat pump water heaters a strong fit, and the federal 25C tax credit offers 30% (up to $2,000) for qualifying heat pump models. Most replacements require a permit, though like-for-like electric swaps may be exempt in some jurisdictions.
