FAQs
Why should I hire a licensed plumber for a tankless water-heater installation in Rogersville?
Tennessee requires a licensed, bonded, and insured plumber for any water-heater installation that involves gas, electrical, or potable-water connections. A licensed professional knows state and Hawkins County code, secures the right permits, performs safe gas-line sizing, installs proper venting, and files the final inspection paperwork. This protects your home from leaks, carbon-monoxide hazards, and voided manufacturer warranties.
How do I know what size (gallons-per-minute) tankless unit my Rogersville home needs?
We calculate demand by adding the flow rates of fixtures you may use at the same time—shower, dishwasher, washing machine, etc.—and adjust for winter groundwater temperature (which averages 52–55 °F in Rogersville). For most 2-bath homes a 6–7 GPM gas unit or an 18–24 kW electric unit is sufficient, while larger households may need 9–11 GPM. During the in-home estimate we measure your gas-line capacity, electrical panel space, and water pressure to recommend the exact model.
How long will the installation take, and will I be without water?
A straightforward replacement of a tank heater with a gas tankless model usually takes 5–7 hours; electric units can be done in 4–6 hours if the panel already has capacity. Complete retrofits that require new venting, gas-line upsizing, or breaker upgrades can take a full day. Water is typically shut off for 1–2 hours, and hot water service is restored before we leave. We schedule around your routine and always keep one bathroom cold-water tap available.
Will a tankless water heater really lower my energy bills in Rogersville’s climate?
Yes. Because tankless units heat water only when you open a tap, they eliminate the 24/7 standby losses of storage tanks. Gas models are up to 98 % efficient, and electric models reach 99 %. In Hawkins County, homeowners switching from a 50-gallon gas tank save 20–40 % on natural-gas use, while those moving from electric tanks save 25–45 % on kWh. The cooler incoming ground water during Rogersville winters slightly reduces efficiency, but overall savings remain substantial year-round.
What maintenance does a tankless water heater require after installation?
Manufacturers recommend an annual service that includes descaling the heat exchanger with a vinegar solution, cleaning the inlet water filter, and testing the gas pressure or electrical connections. Rogersville’s moderate water hardness (4–6 grains per gallon) means scale build-up is slower, but we still advise yearly flushing to keep your warranty valid. We offer low-cost maintenance plans and can install a whole-house sediment filter or softener if needed.
Do you provide warranties or service guarantees on tankless installations?
Absolutely. We are certified installers for Rinnai, Navien, and Rheem, so you receive the full manufacturer warranty—up to 15 years on the heat exchanger and 5 years on parts. Our labor is guaranteed for 2 years, and we include a free first-year maintenance visit. If any workmanship issue arises, we repair it at no charge. Extended protection plans are also available.
