What affects the price

When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.

About this service

The cost to install a tankless system depends on your home’s infrastructure, such as venting requirements and the size of your gas meter. Because these units provide on-demand heat, the installation process is more technical than a standard water heater replacement. We provide a full assessment of your home to determine the final investment required for a seamless upgrade. Exact pricing confirmed free on the call.

Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.

Frequently asked in Chicago

How long do hot water heaters typically last in Chicago?

In Chicago, traditional tank water heaters usually last between 10 and 15 years. Tankless water heaters, with proper upkeep, can often function effectively for 20 years or more. The hard water conditions common in the Chicago area can sometimes affect the lifespan of your unit.

What is the average cost of putting in a water heater in Chicago?

What is the most efficient type of water heater for Chicago homes?

For Chicago homes, tankless water heaters are an efficient option because they heat water on demand, reducing energy waste. This can lead to savings on utility bills, especially during our colder months. They are also more compact than traditional tank models. A consultation will clarify the best choice for you.

What are signs I need a new water heater in my Chicago home?

Look for signs such as your water heater being over 10-15 years old, experiencing leaks, or seeing rusty-colored water. If you have inconsistent hot water temperatures or notice unusual noises, it's a strong indication that a replacement might be needed in your Chicago residence.

What is the most common problem with a hot water heater in Chicago?

Sediment buildup in the tank is a frequent issue in Chicago, impacting efficiency and causing noise. Other common problems include thermostat failures or issues with the heating elements, leading to inadequate hot water. These often require professional attention to resolve.

Is it worth it to repair a water heater in Chicago?

Repairing a water heater in Chicago is often sensible for newer units with straightforward problems, like a minor leak or a faulty igniter. However, for older units that have a history of issues, installing a new, more energy-efficient model could be a better long-term investment. A pro can assess your situation.
