How Much Does a Water Heater Replacement Cost in Chicago? [2026 Data]

Water heater replacement costs in Chicago average $1,143, and most residents pay somewhere between $818 and $1,499. The price you’ll pay depends on the type of unit you want, the fuel source you plan on using, and the size of the water heater you need. The average household size in Chicago is just 2.2 people, which means smaller and more affordable water heaters are the norm in the area.

Water Heater Replacement Cost Factors

Some Chicago residents pay as little as $290 for a new water heater, but prices can climb up to $5,700 if you have a larger home and need a high-capacity water heater, or you want to upgrade to a tankless water heater for more comfort and convenience. Several things can affect your pricing, so consider things like style, fuel source, and capacity to get an accurate estimate.

Size

Hot water heaters come in different sizes, measured by gallons (for tank-style systems) or gallons per minute (for tankless systems). The total amount of your water heater replacement cost will largely depend on the size of your new water heater, and that will depend on the size of your household.

The average household in Chicago is home to just 2.2 people, and smaller homes like this have lower hot water demands and need smaller water heater sizes—usually between 30 and 40 gallons for a tank-style unit or 6 to 10 gallons per minute (GPM) for a tankless water heater. You can use these average prices to get an idea of your cost, but you should always have a water heater installation pro help you determine what size you need.

Since around 80% of Chicago homes use natural gas for heating, a whole-home tankless water heater is a possibility. However, sizing a tankless unit is a bit more complex, so you’ll need a pro to help. For tank-style units, you can get a rough estimate for your total using the table below.

Tank vs. Tankless Water Heaters 

A traditional tank-style water heater stores water in a large tank that holds anywhere from 20 to 100 gallons. If you’re like 90% of households, you have a tank hot water heater sitting on a concrete pad in a basement, laundry room, or utility room. In comparison, a tankless water heater is the size of a small suitcase, has a coil system for heating water, and is usually mounted on the wall. Your water heater installation pro can help you decide which type of water heater is best for your replacement. 

Types of Water Heaters

Most electric and gas water heaters cost between $550 and $1,500, but the unit type will significantly impact your cost. Electric water heaters tend to be a bit more expensive than gas water heaters, and propane water heaters are the most affordable but the least common in Chicago. Around 80% of the homes in Chicago use natural gas as a heating source, so most residents will opt for a gas-fired water heater.

Gas-fired water heaters are not only more affordable up front, but they also have a much higher heat output, so it’s possible to choose a whole-home tankless water heater, which many homeowners wouldn’t be able to do with electric units. Tankless water heaters cost more, though, so there’s a chance that a natural gas unit will be more expensive than an electric one.

Plumber Pro Costs

Labor is more expensive in Chicago than it is in most other cities. Labor costs scale with the local cost of living, which is 12% above the national average in Chicago. Labor accounts for about half of your total installation cost, which means an average labor cost of $570 when you hire a professional water heater installer in Chicago.

All plumbing and mechanical work, including water heater replacement, requires permits in Chicago, so you should budget for the associated permit fees to get an accurate total. The City of Chicago charges a flat fee of $75 for water heater replacement.

Additionally, you should budget for sales tax, which will also add to your total. The sales tax rate in Chicago is 10.25%, including state and city taxes, which is much higher than the national average. Given the water heater replacement cost in Chicago, you’re looking at an average of $117.16 in sales tax.

Do Water Heater Replacements Increase Home Value?

Any upgrade to the mechanical equipment in your home can and should increase the value, as homeowners will have more confidence in the new equipment and may be willing to pay more for the peace of mind it provides. However, the actual return on investment (ROI) will depend on the type of water heater you install.

Tankless water heaters are becoming increasingly popular in Chicago, and they’re generally more desirable, especially because most homes in the area have natural gas connections that can support the high demands you’ll place on your water heater.

According to a study done by Zillow, upgrading to a tankless water heater can boost home value by 1.2%, which would mean an increase of $4,620 in Chicago, given average real estate prices in the city.
