Water heater installation cost by job.
Installed-labor pricing for Lombard, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Lombard typically costs between $800 and $1,800 for a standard tank unit, and $1,800 to $4,600+ for a tankless system. With a median home age of 55 years, many homes require updates to meet current plumbing codes, including the Illinois Plumbing Code.

An expansion tank is needed on closed systems, typically installed on the cold supply line near the water heater.
