Water heater replacement cost by type.
Installed prices for Palos Heights, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Palos Heights, where most homes were built around 1976 and nearly 90% of residents own their property, water heater replacement is a common upgrade. Local installed costs range from $750–$1,850 for a tank gas unit, $850–$2,100 for tank electric, $1,400–$3,300+ for tankless, and $1,700–$3,700 for a heat pump. Given the cold continental climate and winter inlet water temperature, gas water heaters are the typical choice. Illinois law requires a licensed plumber to perform the work, and a permit is needed. Homes with closed systems must have an expansion tank installed on the cold supply line near the heater. The federal 25C tax credit offers up to $2,000 for qualifying heat pump units, but gas remains the most common fuel in the area.

Recommended unit for Palos Heights
Given Illinois’s cold continental (humid) climate and gas water heating, high-efficiency gas is the sensible default for most Palos 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 Palos Heights, explained.
What affects replacement cost in Palos Heights
Prices vary mainly by unit type and labor. Gas tank heaters are generally more affordable than tankless or heat pump models. Older homes (median built 1976) may need additional work like replacing corroded connections or updating venting. Permit fees and the requirement to use a licensed Illinois plumber add to the base cost. If your home has a closed system, an expansion tank is mandatory, which adds $100–$200. The cold winter inlet water can also affect sizing and efficiency choices.
Common water heater problems in Palos Heights
Sediment buildup

Leaking tank

Pilot or ignition failure
