Like-for-Like Tankless Swaps in Spokane Valley

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 done in four to six hours.

Condensing Tankless Replacement in Spokane Valley

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. Constant moisture west of the mountains encourages mold, rot and corrosion around leaks, so small drips should not be ignored. 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.

Exterior Mount Tankless Units in Spokane Valley, WA

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. Disconnecting hoses, insulating crawlspace pipes and protecting hose bibs before the first freeze prevents most winter damage. 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 simplest swap when the gas line is already sized correctly.

Frequently Asked Questions About Tankless Water Heater Replacement in Spokane Valley

The cost of tankless water heater replacement in Spokane Valley, WA usually 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 necessary electrical or gas line upgrades. This price usually includes the unit itself and labor. We provide a written, upfront quote after a thorough assessment of your home.

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.

Often yes, especially when converting from a tank. Many tankless units need three quarter inch gas pipe and a meter that can supply 199,000 BTU on top of your furnace, range and dryer.

New tankless water heaters usually come with a manufacturer's warranty, which usually covers the heat exchanger for 10 to 15 years and parts for 3 to 5 years. FHN Plumbing also provides a labor warranty on our installation work for your peace of mind. We will go over warranty details for your chosen unit during your consultation.

FHN Plumbing installs and replaces all major trusted brands of tankless water heaters. Our preferred brands include Rinnai, Navien, Noritz and Rheem, as they are known for their reliability, energy efficiency and long-term performance. We can also source and install other brands based on your preference or home requirements.

To prepare for tankless water heater replacement, make sure the area around your existing unit is clear and easy to reach for our plumbers. If possible, clear a path to the installation site and keep pets or children away from the work area. We will handle draining the old unit and all other technical preparations.

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.

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.
