Tank to Tankless Conversions in Joplin, MO
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 check 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.

Like-for-Like Tankless Swaps in Joplin
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 done in four to six hours.
Commercial Tankless Water Heater Replacement in Joplin, MO
Businesses in Joplin, MO 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.
Gas Tankless Water Heater Replacement in Joplin
Many homes in Joplin 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 prioritize safety. All gas connections and combustion air requirements meet Missouri and local codes, heading off potential hazards and maximizing efficiency.
Exterior Mount Tankless Units in Joplin, MO
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. Disconnecting hoses, insulating exposed lines and letting faucets drip on bitter nights head off most freeze 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 guard the water and gas lines. Exterior models are often the simplest swap when the gas line is already sized correctly.

Frequently Asked Questions About Tankless Water Heater Replacement in Joplin
The cost of tankless water heater replacement in Joplin, MO 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 detailed, upfront quote after a thorough assessment of your home.
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 FGV Plumbing.
Common signs that your tankless water heater needs replacement include frequent 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 common and costly, replacement is often the more economical choice.
To extend the life and efficiency of your new tankless water heater, regular maintenance is crucial, especially in areas with hard water. This usually involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections. FGV Plumbing offers maintenance plans to help keep your unit in top condition.
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.
Most jurisdictions in Missouri require a permit for water heater replacement, especially when gas piping or venting changes. We take care of permits where they are required.
FGV Plumbing installs and replaces all major reputable 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.
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.
