Exterior Mount Tankless Units in Benton, AR
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. Before a deep freeze, disconnect hoses, drip a faucet on outside walls, and know where your main shutoff is located. 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.

Many homes in Benton rely on natural gas for water heating, and gas tankless units are a highly efficient option.

We put a priority on safety. All gas connections and combustion air requirements meet Arkansas and local codes, heading off potential hazards and maximizing efficiency.

Tank to Tankless Conversions in Benton, AR
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. Expect a conversion to take a full day.

Frequently Asked Questions About Tankless Water Heater Replacement in Benton
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 any work starts.
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.
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.
To extend the life and efficiency of your new tankless water heater, regular maintenance is key, especially in areas with hard water. This typically involves annual flushing to remove mineral buildup, checking the air filter, and inspecting gas and water connections. DGR Plumbing offers maintenance plans to help keep your unit in top condition.
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 largest difference.
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.
DIY tankless water heater replacement is usually 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 DGR 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.
