FAQs
What are the main benefits of switching to a tankless water heater in Sevierville?
A properly sized tankless unit provides endless hot water on-demand, so you never run out during back-to-back showers or when filling a large whirlpool tub. Because it fires only when a tap is opened, it can cut water-heating energy use by 24–34 %, lowering Sevierville electric or natural-gas bills. Tankless models mount on the wall, freeing up to 16 ft² of floor space, last 20+ years (about twice as long as a storage tank), and greatly reduce the risk of catastrophic leaks—an important consideration for vacation cabins and rental properties common in the Smokies.
How do I determine the right size (GPM) tankless unit for my home?
Sizing is based on the peak gallons-per-minute (GPM) demand and the temperature rise required. First, add up the flow rates of fixtures you might run at the same time—e.g., two showers (2.0 GPM each) plus a dishwasher (1.5 GPM) equals 5.5 GPM. Next, calculate temperature rise: Sevierville’s incoming water averages 55 °F; to reach 120 °F you need a 65 °F rise. A unit that can deliver at least 5.5 GPM at a 65 °F rise is required. Our technicians will verify fixture flow rates, account for winter inlet temps, discuss gas vs. electric models, and recommend the appropriately sized appliance so you always have ample hot water without overspending on capacity.
Does Sevierville’s mineral-rich water affect tankless performance, and what maintenance is needed?
The limestone geology of East Tennessee produces moderately hard water, which can leave scale inside heat exchangers. To keep your warranty valid and maintain full efficiency, plan on a simple annual service: we isolate the unit with built-in flush valves, circulate food-grade vinegar or descaling solution for 30–45 minutes, and clean the inlet screen. Homes with very hard water may benefit from an inexpensive inline sediment filter or a whole-house softener. With this routine care, a tankless heater will run efficiently for two decades or more.
How long does installation take and will I be without hot water during the process?
For most retrofit projects, our licensed plumbers and gasfitters complete the job in one day—typically 4–6 hours. We shut off water and gas for roughly 1–2 hours while removing the old tank, upgrading venting and gas lines if needed, and setting the new unit. You’ll have running cold water for other household uses during most of the project, and we won’t leave until hot water is flowing and the system is fully tested.
What kind of energy savings and incentives are available for Sevierville residents?
Homeowners switching from a standard electric tank can save $80–$150 per year; natural-gas users often save 10–20 %. Sevier County Electric System and local gas utilities periodically offer $100–$300 rebates on qualifying ENERGY STAR® tankless models. In addition, the current federal Energy Efficient Home Improvement tax credit lets you claim 30 % of the equipment and installation cost (up to $600) on your taxes. We provide the documentation you’ll need for both utility rebates and tax filings.
Are permits required for a tankless water heater installation in Sevierville, and do you handle them?
Yes. Both the City of Sevierville and Sevier County require mechanical and (for gas units) fuel-gas permits. Proper venting, gas-line sizing, electrical connections, and combustion air must pass inspection. Our team pulls all necessary permits, schedules the inspection, and is on-site to meet the inspector—saving you time and ensuring the installation is fully code-compliant and covered by manufacturer and workmanship warranties.
