Water heater replacement cost by type.
Installed prices for Chicago Heights, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Chicago Heights, where the median home was built in 1958, water heater replacement is a common upgrade. With cold continental winters and cold inlet water, a reliable unit is essential. Most homes use gas water heaters, and replacement must be done by an Illinois-licensed plumber. Permits are required under the Illinois Plumbing Code, and an expansion tank is needed on closed systems. Typical installed costs range from $700–$1,750 for a tank gas unit, $800–$1,900 for tank electric, $1,300–$3,000+ for tankless, and $1,550–$3,500 for a heat pump. The federal 25C tax credit offers 30% up to $2,000 for qualifying heat pump models, making them a more affordable option long-term despite higher upfront cost.

Recommended unit for Chicago Heights
Given Illinois’s cold continental (humid) climate and gas water heating, high-efficiency gas is the sensible default for most Chicago Heights homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

Water Heater Replacement in Chicago Heights, explained.
What affects water heater replacement cost in Chicago Heights?
Prices vary by unit type and labor. Gas tank units are generally more affordable than heat pumps, but heat pumps qualify for the 25C tax credit. Older homes (median built 1958) may require code upgrades like expansion tanks or venting modifications, adding to labor. Permit fees and the need for a licensed plumber also factor in. Tankless units cost more upfront but save space and energy. Winter inlet water temperature increases recovery time, so sizing matters.
