FAQs
What advantages does a tankless water heater offer over a traditional tank in Ducktown?
Tankless units heat water on demand, so you’re not paying to keep 40–80 gallons hot all day. That translates into energy savings of 20–40 %, lower utility bills, and endless hot water for large families or back-to-back showers. Because they’re wall-mounted, you regain floor space—important in the smaller basements and crawl spaces common in Ducktown homes. The sealed combustion design also reduces the risk of leaks and water damage that traditional tanks can cause.
How do I determine the correct size (flow rate and BTU) for my Ducktown household?
Sizing is based on the peak gallons-per-minute (GPM) you’ll need and the temperature rise between your incoming water and desired hot-water temperature. We start by adding up simultaneous fixtures—e.g., a 1.8 GPM shower + 1.5 GPM sink = 3.3 GPM. In Ducktown, ground-water temperature averages about 55 °F, so to reach 120 °F you need a 65 °F rise. A unit rated for at least 3.5 GPM at a 65 °F rise would be recommended. Our installers perform a free on-site calculation to match you with the right model and avoid hot-water shortages.
How long does installation take, and will I be without water?
A standard replacement—removing the old tank, mounting the tankless heater, running gas or electric upgrades, and venting—typically takes 6–8 hours. Your cold-water supply remains on for most of the day; hot water is shut off during the swap-over, usually 3–4 hours. We schedule installations at your convenience and can provide temporary water if needed. Same-day hot-water restoration is guaranteed.
Does Ducktown’s moderately hard water affect tankless performance?
Yes, mineral buildup can reduce efficiency over time, but the impact is manageable. We install an isolation valve kit and recommend a simple descaling flush once a year—less than an hour of labor. Adding an inline sediment filter or water softener further protects the heat exchanger. Following this maintenance schedule keeps your warranty valid and extends service life to 20+ years.
Will your plumbing team handle permits, venting, and gas-line upgrades?
Absolutely. Ducktown requires a mechanical permit and, for gas units, a pressure test. Our licensed plumbers pull all permits, coordinate inspections, size and run new gas lines if your existing meter or piping is undersized, and install Category III or IV stainless venting that meets manufacturer specs. We also test for carbon-monoxide leaks and take care of hauling away your old tank at no extra charge.
Are there rebates or tax incentives available for energy-efficient tankless water heaters in Ducktown?
Yes. Tennessee Valley Authority participants can receive up to a $300 utility rebate for qualifying ENERGY STAR® tankless models. In addition, the federal Inflation Reduction Act offers a 30 % tax credit (up to $600) on the unit and installation costs. We provide itemized receipts and the necessary documentation so you can easily claim both incentives, helping offset the upfront investment.
