Commercial Tankless Replacement in Old Town
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 share the load. We check gas pressure under full demand, since commercial racks can draw more than 600,000 BTU combined. Scheduling is flexible, so we can work after hours and keep your business open. We also set up a descaling schedule matched to your water usage.

Condensing Tankless Replacement in Old Town
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 low-cost 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. Around Old Town, coastal dampness and winter storms can add moisture and stress to older plumbing and outdoor fixtures. 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 the price.

For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a viable choice.

We make sure your new electric tankless unit is installed safely and effectively, providing on-demand hot water without the need for gas lines.

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 seized. Most like-for-like swaps are finished in four to six hours.
