Navien Tankless Water Heater Replacement in Durham, NH
Navien tankless water heaters are popular for their condensing technology, offering high efficiency and performance. When it is time for a Navien tankless water heater replacement in Durham, NH, you can count on FVR Plumbing. We have broad experience with Navien's advanced systems, including their combination boiler and water heater units.

Recirculation Tankless Upgrades in Durham, NH
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 popular in long single-story ranch homes.
Exterior Mount Tankless Units in Durham, NH
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 break down plastic covers and wiring over time. Pipes in exterior walls, crawlspaces, camps and vacation properties are especially likely to freeze when the heat is turned down. 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 easiest swap when the gas line is already sized correctly.
Emergency Tankless Replacement in Durham, NH
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 (844) 442-1569 any time your tankless quits.
Electric Tankless Water Heater Replacement in Durham, NH
For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a practical choice. FVR Plumbing offers electric tankless water heater replacement services in Durham, NH. This often involves careful assessment of your home's electrical panel capacity, as these units require substantial 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.
Commercial Tankless Replacement in Durham
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 split 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.
Tankless vs. Tank Water Heater Replacement Cost in Durham, NH
When considering tankless water heater replacement in Durham, NH, 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.

Frequently Asked Questions About Tankless Water Heater Replacement in Durham
A like-for-like gas tankless replacement typically runs $2,800 to $4,500 installed, depending on the brand and venting. Converting from a tank to tankless often costs $4,000 to $6,500 because of gas line and venting upgrades. We give you a written quote before we start any work.
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 real savings on your utility bills over time, especially in homes with varying hot water usage.
Most jurisdictions in New Hampshire require a permit for water heater replacement, especially when gas piping or venting changes. We take care of permits where they are required.
We install Navien, Rinnai, Noritz, Takagi and Rheem tankless heaters. Each has its own strengths, and we recommend based on your flow needs, venting options and budget.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail much sooner. Annual flushing makes the biggest difference.
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.
With proper installation and regular maintenance, a new tankless water heater typically lasts 20 to 25 years. This is much 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.
Yes, you can absolutely replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners looking for better energy efficiency and endless hot water.
