Exterior Mount Tankless Units in Ankeny, IA
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 homeowners shut off outdoor spigots in the fall, and many use heat tape or pipe insulation on vulnerable runs. 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 easiest swap when the gas line is already sized correctly.
Commercial Tankless Replacement in Ankeny
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 suited to your water usage.
Tank to Tankless Conversions in Ankeny, IA
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.
Like-for-Like Tankless Swaps in Ankeny
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.

Frequently Asked Questions About Tankless Water Heater Replacement in Ankeny
A like-for-like gas tankless replacement usually runs $2,800 to $4,500 installed, depending on the brand and venting. Converting from a tank to tankless often costs $4,000 to $6,500 because of gas line and venting upgrades. We give you a written quote before any work starts.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail much sooner. Annual flushing makes the largest difference.

Yes, you can certainly replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners looking for better energy efficiency and endless hot water. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation important for safety and performance.
Yes, tankless water heaters are usually 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.
A standard tankless water heater replacement usually 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.
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 for you.
We install Navien, Rinnai, Noritz, Takagi and Rheem tankless heaters. Each has its own strengths, and we recommend based on your flow needs, venting options and budget.
