Recirculation Tankless Upgrades in Redmond, WA

If you are tired of running the tap while you wait for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use in check while saving thousands of gallons of wasted water a year. This upgrade is a favorite in long single-story ranch homes.

Gas Tankless Water Heater Replacement in Redmond

Many homes in Redmond 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 Washington and local codes, preventing potential hazards and maximizing efficiency.

Exterior Mount Tankless Units in Redmond, 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. Hard freezes are infrequent on the west side of Washington, but short cold snaps catch many homes with uninsulated pipes off guard. 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.

Electric Tankless Water Heater Replacement in Redmond, WA

For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a practical choice. FHN Plumbing offers electric tankless water heater replacement services in Redmond, WA. This often involves careful 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 correctly, providing on-demand hot water without the need for gas lines.

Tank to Tankless Conversions in Redmond, WA

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 evaluate 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.

Emergency Tankless Replacement in Redmond, WA

A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can usually get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak as soon as we arrive. Call (425) 491-3131 anytime your tankless quits.

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 also replace the old service valves if they are corroded or seized. Most like-for-like swaps are finished in four to six hours.

Frequently Asked Questions About Tankless Water Heater Replacement in Redmond

The cost for tankless water heater replacement in Redmond, WA usually ranges from $3,000 to $6,000, depending on the unit's brand, capacity, fuel type (gas or electric) and any needed changes to gas lines, electrical or venting. This estimate includes both the new unit and professional installation. We always provide a detailed quote upfront after assessing your needs.

A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, usually takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to extra plumbing, gas or electrical changes required for proper installation and venting.

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 significant savings on your utility bills over time, particularly in homes with varying hot water usage.

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.

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.

Yes. Softened or scale-treated water greatly reduces mineral buildup in the heat exchanger. We can install a scale-reduction filter if a full softener is not in your plans.

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

DIY tankless water heater replacement is generally not recommended due to the complexity of gas lines, high-voltage electricity, water connections and venting requirements. Improper installation can lead to dangerous gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like FHN Plumbing.
