Residential Tankless Water Heater Replacement in Wenatchee
For homeowners in Wenatchee, upgrading to a tankless water heater offers significant benefits like endless hot water and reduced energy use. We assess your household's hot water demand to recommend the ideal sized unit, so you get strong performance.

Like-for-Like Tankless Swaps in Wenatchee
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.
Tankless vs. Tank Water Heater Replacement Cost in Wenatchee, WA
When considering tankless water heater replacement in Wenatchee, WA, it is natural to compare costs. While the upfront installation of a tankless unit can be higher than a traditional tank, the long-term energy savings and longer lifespan often make it the more cost-effective choice. We provide honest, upfront pricing for both options. That helps you make an informed decision based on your budget and hot water needs, with no surprises.
Gas Tankless Water Heater Replacement in Wenatchee
Many homes in Wenatchee rely on natural gas for water heating, and gas tankless units are a highly 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 put a priority on safety. All gas connections and combustion air requirements meet Washington and local codes, preventing potential hazards and maximizing efficiency.
Commercial Tankless Replacement in Wenatchee
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 easy to work around, so we can work after hours and keep your business open. We also set up a descaling schedule matched to your water usage.
Exterior Mount Tankless Units in Wenatchee, 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 covering 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.
Commercial Tankless Water Heater Replacement in Wenatchee, WA
Businesses in Wenatchee, WA often require robust hot water solutions, and tankless systems can provide the efficiency and capacity needed. We specialize in replacing commercial tankless units for restaurants, offices and other facilities with minimal disruption to your operations. Our plumbers are experienced with high-capacity models and complex plumbing layouts. We deliver a steady hot water supply that meets your business's demands and health code requirements.

Emergency Tankless Replacement in Wenatchee, 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.

Frequently Asked Questions About Tankless Water Heater Replacement in Wenatchee
The cost for tankless water heater replacement in Wenatchee, WA typically 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 will provide a detailed quote upfront after assessing your needs.
We do not recommend it. Gas line sizing, venting clearances and combustion testing call for training, and improper installs can void the warranty or create carbon monoxide hazards.
Common signs that your tankless water heater needs replacement include repeated error codes, inconsistent water temperature, reduced hot water flow or a complete lack of hot water. If your unit is over 15 to 20 years old and repairs are becoming frequent and costly, replacement is often the more economical choice.
With proper installation and regular maintenance, a new tankless water heater typically lasts 20 to 25 years. This is significantly longer than traditional tank water heaters, which usually last 10 to 15 years. Regular flushing and descaling can help extend the life of your tankless unit, especially in hard water areas.
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 on your behalf.
New tankless water heaters typically come with a manufacturer's warranty on the heat exchanger, usually 10 to 15 years, and on parts, usually 3 to 5 years. FHN Plumbing also provides a warranty on our installation workmanship. We will go over all warranty details with you before your replacement so you understand your coverage.
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 serious gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like FHN Plumbing.
Repeated error codes, fluctuating temperature, water leaking from inside the cabinet and a unit older than 15 years are common signs. If the heat exchanger is leaking, replacement is typically the better value.
