Water heater installation cost by job.
Installed-labor pricing for River Forest, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In River Forest, where the median home was built around 1946, many older homes still have original or aging water heaters. With cold continental winters and cold inlet water, a reliable gas water heater is a strong fit for most households. Typical installation costs for a standard tank range from $750 to $1,700, while tankless units run $1,700 to $4,200 or more, plus $275–$950 for a new gas line if needed. Illinois requires a permit for water heater replacement, and work must be done by a licensed plumber. An expansion tank is required on closed systems, adding to the project cost.
