Water heater replacement cost by type.
Installed prices for Arlington Heights, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Arlington Heights, where the median home was built in 1973, many water heaters are reaching or past their expected lifespan. With cold continental winters and cold inlet water, a reliable replacement is essential. Typical installed costs for a gas tank water heater, the recommended choice given the area's gas heating prevalence, range from $900 to $2,200. Illinois requires a licensed plumber for installation, and a permit is needed. An expansion tank is required on closed systems, adding to the cost. Local labor rates and the need to comply with the Illinois Plumbing Code influence pricing.

Recommended unit for Arlington Heights
Given Illinois’s cold continental (humid) climate and gas water heating, high-efficiency gas is the sensible default for most Arlington 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.

Why Prices Vary in Arlington Heights
The age of your home (median 1973) can affect labor if old piping or venting needs updating. Unit type matters: gas tank is more affordable than tankless or heat pump. A heat pump qualifies for a federal 25C tax credit (30%, up to $2,000), lowering net cost. Permit fees and expansion tank requirements add $100–$300. Accessibility of the installation site and any code upgrades also influence the final price.
Common Water Heater Issues in Arlington Heights
Sediment Buildup
Hard water and age cause sediment at the tank bottom, reducing efficiency and causing rumbling noises.
Corrosion and Leaks
Older tanks (especially in homes built in the 1970s) are prone to rust and leaks, often requiring full replacement.
Pilot Light or Ignition Failure
Gas water heaters in cold climates may have pilot light outages or faulty thermocouples, leading to no hot water.
What to Expect During Replacement
A licensed plumber will first disconnect gas, water, and vent lines, then remove the old unit. They'll inspect and upgrade connections to meet current Illinois code, including installing an expansion tank if needed. After placing the new water heater, they'll test for leaks and proper operation. The job typically takes 4–6 hours, and a permit from the village is required.
