Electric Tankless Water Heater Replacement in Kent, WA

For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a viable choice. FHN Plumbing offers electric tankless water heater replacement services in Kent, WA. This often involves close assessment of your home's electrical panel capacity, as these units require significant amperage. We make sure your new electric tankless unit is installed safely and effectively, providing on-demand hot water without the need for gas lines.

Like-for-Like Tankless Swaps in Kent

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.

Rinnai is a leading brand in the tankless water heater market, known for its quality and engineering. If your Rinnai unit is aging or malfunctioning, FHN Plumbing provides expert Rinnai tankless water heater replacement in Kent.

Our technicians are familiar with the installation requirements and venting options for Rinnai models, so the upgrade goes cleanly.

Exterior Mount Tankless Units in Kent, 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 shield the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.
