Exterior Mount Tankless Units in Arlington Heights, 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 break down plastic covers and wiring over time. Water and sewer lines must be buried well below the frost line to avoid freezing, and shallow lines are a common source of winter trouble. 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 guard the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.

Residential Tankless Water Heater Replacement in Arlington Heights
For homeowners in Arlington Heights, upgrading to a tankless water heater offers real benefits like endless hot water and reduced energy use. We assess your household's hot water demand to recommend the right sized unit, so you get optimal performance. Our team handles everything from safely disconnecting your old unit to installing the new tankless system. That includes any needed gas and water line adjustments and venting changes to meet current codes.
Commercial Tankless Replacement in Arlington Heights
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.
Tank to Tankless Conversions in Arlington Heights, 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 often 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. Plan for a conversion to take a full day.
Condensing Tankless Replacement in Arlington Heights
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by capturing heat from exhaust gases. They vent through inexpensive PVC and produce acidic condensate that must be neutralized and drained properly. We install a neutralizer cartridge and route the condensate line to an approved drain. Illinois has cold winters and hot, humid summers, and those seasonal extremes put steady stress on pipes, water heaters, and sump pumps. Condensing units still save gas because they work year-round on showers, laundry and dishes. We explain the cost difference so you can decide if the efficiency gain is worth it.
Gas Tankless Water Heater Replacement in Arlington Heights
Many homes in Arlington Heights rely on natural gas for water heating, and gas tankless units are a very efficient option. Our gas tankless water heater replacement service includes thorough inspection of your existing gas lines, proper sizing of new gas lines if needed, and secure venting to the outdoors. We prioritize safety. All gas connections and combustion air requirements meet Illinois and local codes, heading off potential hazards and maximizing efficiency.
Electric Tankless Water Heater Replacement in Arlington Heights, IL
For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a practical choice. HVM Plumbing offers electric tankless water heater replacement services in Arlington Heights, IL. This often involves close assessment of your home's electrical panel capacity, as these units require substantial amperage. We make sure your new electric tankless unit is installed safely and correctly, providing on-demand hot water without the need for gas lines.

Like-for-Like Tankless Swaps in Arlington Heights
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 quickest 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.

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.
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.
Yes, tankless water heaters are generally more energy-efficient than traditional tank models. They only heat water on demand, eliminating the standby heat loss that comes with keeping a large tank of water hot. This can lead to real savings on your utility bills over time, particularly in homes with varying hot water usage.
Common signs that your tankless water heater needs replacement include frequent error codes, inconsistent water temperature, reduced hot water flow or a complete lack of hot water. If your unit is over 15 to 20 years old and repairs are becoming common and costly, replacement is often the more economical choice.
A direct swap usually takes four to six hours. A tank to tankless conversion with new gas and venting usually takes a full day.
Most manufacturers offer 10 to 15 years on the heat exchanger and about 5 years on parts for residential use. We add our own labor warranty and register the unit on your behalf.
A standard tankless water heater replacement typically takes between 4 and 8 hours. This timeframe can vary based on whether we are replacing an existing tankless unit with a similar model or upgrading from a traditional tank water heater. A tank conversion can call for more extensive changes to gas lines, electrical or venting.
