Why Choose BGV Plumbing for Tankless Water Heater Replacement in Memphis, TN?
Private wells serve many rural homes in Tennessee, and some well water carries iron, sulfur or sediment that calls for filtration or treatment. Hard water is tough on tankless heat exchangers, and many early failures trace back to scale and skipped flushing. We size, install and set up each replacement so it stands up to your local water supply.
- Space Saving, Their compact design lets tankless units fit in smaller spaces, freeing up useful room in your utility closet or garage.
- Energy Savings, Tankless water heaters only heat water when you need it, which can noticeably reduce energy use compared to traditional tank models, a big plus for Tennessee utility bills.
- Longer Lifespan, Tankless water heaters typically last longer than conventional tank units, often up to 20 years with proper maintenance, giving you better long-term value.

Recirculation Tankless Upgrades in Memphis, TN
If you are tired of running the tap waiting 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 reasonable while saving thousands of gallons of wasted water a year. This upgrade is popular in long single-story ranch homes.

Emergency Tankless Water Heater Replacement in Memphis
A sudden tankless water heater failure can leave your Memphis home without hot water, which is a major inconvenience. BGV Plumbing offers emergency tankless water heater replacement to restore your hot water fast. We put a priority on urgent situations, working to diagnose the issue and, if replacement is necessary, get a new unit installed as soon as possible. Our goal is to cut down your downtime and get your home back to normal with reliable hot water.
Tank to Tankless Conversions in Memphis, TN
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. Expect a conversion to take a full day.
Gas Tankless Water Heater Replacement in Memphis
Many homes in Memphis 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 Tennessee and local codes, preventing potential hazards and maximizing efficiency.
Exterior Mount Tankless Units in Memphis, TN
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 crawlspaces, exterior walls and attics are the most vulnerable during a cold snap, especially where insulation is thin or missing. 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.
Commercial Tankless Water Heater Replacement in Memphis, TN
Businesses in Memphis, TN 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.
Like-for-Like Tankless Swaps in Memphis
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 stuck. Most like-for-like swaps are finished in four to six hours.

Commercial Tankless Replacement in Memphis
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 easy to work around, so we can work after hours and keep your business open. We also set up a descaling schedule suited to your water usage.

Frequently Asked Questions About Tankless Water Heater Replacement in Memphis
The cost of tankless water heater replacement in Memphis, TN 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.
BGV Plumbing installs and replaces all major trusted brands of tankless water heaters. Our preferred brands include Rinnai, Navien, Noritz and Rheem, as they are known for their reliability, energy efficiency and long-term performance. We can also order and install other brands based on your preference or home requirements.
Often yes, especially when converting from a tank. Many tankless units need three quarter inch gas pipe and a meter that can supply 199,000 BTU on top of your furnace, range and dryer.
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 biggest difference.
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.
New tankless water heaters typically come with a manufacturer's warranty, which usually covers the heat exchanger for 10 to 15 years and parts for 3 to 5 years. BGV Plumbing also provides a labor warranty on our installation work for your peace of mind. We will go over warranty details for your chosen unit during your consultation.
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.
Yes, in most areas of Memphis and Tennessee, a permit is required for tankless water heater replacement, especially if it involves gas line changes or significant electrical work. Our team at BGV Plumbing will handle all required permitting so your installation is fully compliant with local building codes and safety regulations.
