Water heater replacement cost by type.
Installed prices for Lisle, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Lisle, Illinois, where the median home was built in 1982 and winter inlet water is cold, water heater replacement is a common upgrade for homeowners. Typical installed costs for a gas tank water heater range from $750 to $1,850, with tankless models running $1,400 to $3,300+. Because Illinois requires a licensed plumber and a permit for water heater installation, labor and permit fees are part of the total. Given the cold continental climate and the prevalence of gas heating in the area, a gas water heater is often the recommended choice for its efficiency and lower operating cost.

Hard water and age (homes from 1982) can cause sediment accumulation, reducing efficiency and leading to early failure.
