Water heater installation in Geneva, Illinois typically costs between $750 and $1,700 for a standard tank unit, and $1,700 to $4,200+ for a tankless system. With 82.5% homeownership and a median home built in 1986, many homes need replacement of aging units.

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