Water heater installation cost by job.
Installed-labor pricing for Ottawa, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Ottawa, Kansas typically costs between $650 and $1,500 for a standard tank unit, and $1,500 to $3,700+ for a tankless system. With many homes built around 1966, older plumbing and gas lines may require upgrades, adding $250–$800 for a new gas line.

The federal 25C tax credit offers 30% back (up to $2,000) on heat pump water heaters, which can offset higher upfront costs.
