Cost to Water Heater Replacement in Chicago, IL (2026)

If you’re budgeting a water heater replacement in Chicago, most projects run $797-$2,278, 14% above the $1,200 national average. What moves that number most is usually one thing: Tank vs. Tankless.

Easiest place to save: The federal heat pump water heater tax credit (30%, up to $2,000 under the Inflation Reduction Act) is one of the best available - if your space allows it, a heat pump unit often pays back in 3-5 years even after accounting for the higher upfront cost.
