Tank to Tankless Conversions in Des Plaines, IL
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units usually need a larger gas line, often three quarter inch or bigger, plus new venting. We check your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Expect a conversion to take a full day.
Like-for-Like Tankless Swaps in Des Plaines
When your existing tankless has a cracked heat exchanger or a failed control board that is not worth repairing, a direct replacement is often the fastest fix. We match the new unit to your current gas line, venting type and mounting location whenever possible. Many Rinnai and Navien models share similar footprints, which keeps wall patching to a minimum. We also replace the old service valves if they are corroded or stuck. Most like-for-like swaps are finished in four to six hours.
Emergency Tankless Replacement in Des Plaines, IL
A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can often get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak as soon as we arrive. Call (773) 903-7643 any time your tankless quits.
Tankless vs. Tank Water Heater Replacement Cost in Des Plaines, IL
When considering tankless water heater replacement in Des Plaines, IL, it is natural to compare costs. While the upfront installation of a tankless unit can be higher than a traditional tank, the long-term energy savings and longer lifespan often make it the more economical choice. We provide clear, upfront pricing for both options. That helps you make an informed decision based on your budget and hot water needs, with no surprises.
Exterior Mount Tankless Units in Des Plaines, IL
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can wear out plastic covers and wiring over time. Most Illinois homeowners shut off and drain outdoor spigots in the fall, and many keep cabinet doors open and faucets dripping on the coldest nights. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to shield the water and gas lines. Exterior models are often the simplest swap when the gas line is already sized correctly.
Rinnai Tankless Water Heater Replacement in Des Plaines
Rinnai is a leading brand in the tankless water heater market, known for its quality and innovation. If your Rinnai unit is aging or malfunctioning, HVM Plumbing provides expert Rinnai tankless water heater replacement in Des Plaines. We make sure your new Rinnai unit is installed correctly, extending its efficiency and lifespan. Our technicians know the installation requirements and venting options for Rinnai models, so the upgrade goes cleanly.
Commercial Tankless Replacement in Des Plaines
Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they split the load. We check gas pressure under full demand, since commercial racks can draw more than 600,000 BTU combined. Scheduling is easy to work around, so we can work after hours and keep your business open. We also set up a descaling schedule matched to your water usage.

Many homes in Des Plaines rely on natural gas for water heating, and gas tankless units are a highly efficient option.

Frequently Asked Questions About Tankless Water Heater Replacement in Des Plaines
The cost of tankless water heater replacement in Des Plaines, IL typically ranges from $3,000 to $6,000, depending on the unit's capacity, brand, complexity of installation, such as converting from a tank model, and any needed electrical or gas line upgrades. This price usually includes the unit itself and labor. We provide a detailed, upfront quote after a thorough assessment of your home.
We do not recommend it. Gas line sizing, venting clearances and combustion testing require training, and improper installs can void the warranty or create carbon monoxide hazards.
New tankless water heaters typically come with a manufacturer's warranty on the heat exchanger, usually 10 to 15 years, and on parts, usually 3 to 5 years. HVM Plumbing also provides a warranty on our installation workmanship. We will review all warranty details with you before your replacement so you understand your coverage.
Yes. Softened or scale-treated water sharply reduces mineral buildup in the heat exchanger. We can install a scale-reduction filter if a full softener is not in your plans.
To extend the life and efficiency of your new tankless water heater, regular maintenance is key, especially in areas with hard water. This usually involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections. HVM Plumbing offers maintenance plans to help keep your unit in top condition.
Tankless water heater replacement is a complex job that involves gas lines, electrical wiring, water connections and venting. It is strongly recommended to hire a licensed professional like HVM Plumbing due to the safety risks and potential for improper installation, which can lead to leaks, gas hazards or inefficient operation. Professionals also protect code compliance and warranty validity.
We install Navien, Rinnai, Noritz, Takagi and Rheem tankless heaters. Each has strengths, and we recommend based on your flow needs, venting options and budget.
With proper installation and regular maintenance, a new tankless water heater usually lasts 20 to 25 years. This is much longer than traditional tank water heaters, which usually last 10 to 15 years. Regular flushing and descaling can help extend the life of your tankless unit, especially in areas with hard water.
