Exterior Mount Tankless Units in Concord, 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. Frozen pipes are a regular winter risk in New Hampshire, especially during long stretches of subzero nights and strong wind. 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.
Tank to Tankless Conversions in Concord, NH
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 usually 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.
Condensing Tankless Replacement in Concord
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by recovering heat from exhaust gases. They vent through low-cost 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. Long, cold winters are the main stress on plumbing in New Hampshire, and the heating season can last for many months. 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.
Electric Tankless Water Heater Replacement in Concord, 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 Concord, 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.
Gas Tankless Water Heater Replacement in Concord
Many homes in Concord rely on natural gas for water heating, and gas tankless units are a very efficient option. Our gas tankless water heater replacement service includes careful 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 New Hampshire and local codes, heading off potential hazards and maximizing efficiency.
Emergency Tankless Replacement in Concord, 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 often 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 anytime your tankless quits.

Frequently Asked Questions About Tankless Water Heater Replacement in Concord
The cost of tankless water heater replacement in Concord, NH typically 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 needed 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, in most areas of Concord and New Hampshire, a permit is required for tankless water heater replacement, especially if it involves gas line changes or major electrical work. Our team at FVR Plumbing will handle all necessary permitting so your installation is fully compliant with local building codes and safety regulations.
Well-maintained tankless units can last 15 to 20 years. In hard water areas without regular descaling, heat exchangers can fail far sooner. Annual flushing makes the largest difference.
Yes. Softened or scale-treated water sharply reduces mineral buildup in the heat exchanger. We can install a scale-reduction filter if a full softener is not in your plans.
With proper installation and regular maintenance, a new tankless water heater usually 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 areas with hard water.
Frequent 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 usually the better value.
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.
Yes, you can certainly 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. However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation important for safety and performance.
