FAQs
What are the main advantages of switching to a tankless water heater in New Tazewell?
Tankless units heat water on demand, so you’re only using energy when someone opens a tap. That typically cuts utility costs 20–40 % versus a storage-tank heater. They never “run out” of hot water, free up floor space, last 18–25 years (roughly double a tank), and qualify for federal tax credits and many Tennessee Valley Authority rebates. Because the water is not stored, there is far less risk of leaks, rust, or legionella growth—important in our humid East Tennessee climate.
How long does a professional tankless water heater installation take?
For most single-family homes in New Tazewell, a straightforward replacement of a standard gas or electric tank can be completed in 4-8 hours. The process involves removing the old tank, mounting the new wall-hung unit, running venting and condensate lines (for gas models), making gas or electrical upgrades if needed, and flushing the plumbing to remove debris. Complex jobs—such as routing long vent runs, relocating the unit, or upsizing the gas line—can extend the time to one full workday. Our plumbers schedule a free on-site visit first so you know exactly how many hours and what costs to expect.
Will a tankless water heater really lower my utility bills enough to justify the higher upfront cost?
Yes, in most cases. A conventional 50-gallon electric tank runs 3,000–4,500 watts all day to keep water hot, while a properly sized electric tankless unit uses power only when a fixture calls for hot water. Gas tankless models run at 80 %+ efficiency (95 % for condensing units) versus 60-65 % for an older atmospheric tank. In Claiborne County, where electricity rates average 10–11¢/kWh and natural gas is modestly priced, our customers see payback in 3–6 years through lower energy bills and the longer service life of the equipment.
How do I know what size (GPM) tankless water heater my household needs?
We calculate size by summing the gallons per minute (GPM) flow of the fixtures you might use simultaneously—e.g., shower (2.0 GPM) + kitchen sink (1.5 GPM) + washing machine (2.0 GPM) ≈ 5.5 GPM total. Then we match that flow to the unit’s output at the incoming winter water temperature, which averages 52–55 °F in New Tazewell. For most three-bedroom homes a 7–9 GPM gas condensing model or a pair of 18–27 kW electric units will cover peak demand. We size every system during the estimate, ensuring you never experience a drop in water temperature.
Will I need to upgrade my gas line or electrical service?
Possibly. High-efficiency gas tankless heaters require a ¾-inch gas supply and up to 199,000 BTU input; many existing homes have only a ½-inch line, so we may need to run a new branch from the meter. Electric tankless units above 18 kW need 150–200 amp service and dedicated double-pole breakers. During your consultation we measure gas pressure, line diameter, and panel capacity. If upgrades are necessary, our licensed plumbers and partnered electricians handle the permitting and work so everything meets Tennessee Mechanical and Electrical Codes.
How often should a tankless water heater be serviced, and what does maintenance involve?
Manufacturers recommend annual maintenance in areas with moderate to hard water like ours (New Tazewell averages 7–9 grains per gallon). Service includes descaling the heat exchanger with food-grade vinegar, cleaning the inlet screen and combustion fan (gas models), checking venting, flushing condensate traps, and verifying gas pressure or amp draw. The visit takes about one hour, keeps your warranty valid, and prevents mineral buildup that can cut efficiency 10–15 %. We offer affordable maintenance plans and send reminders so you don’t have to keep track of the schedule.
