Water heater installation cost by job.
Installed-labor pricing for Chicago Heights, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Chicago Heights typically costs between $700 and $1,550 for a standard tank unit, and $1,550 to $3,900+ for a tankless system. With many homes built around 1958, older plumbing and gas lines may need upgrades, adding $250–$850 for a new gas line.
