FAQs

What advantages does a tankless water heater offer for homes in Sevierville?

Tankless units heat water on demand, so you never run out of hot water—ideal for vacation-rental turnovers common in Sevierville. They are typically 20–40 % more energy-efficient than storage tanks, freeing up utility-bill savings despite our area’s varied seasonal temperatures. Because they mount on a wall, you reclaim valuable floor space, and the stainless-steel heat exchangers resist the mineral content often found in local well-water systems, giving you a longer service life (up to 20 years or more).

How can I tell if my home is compatible with a tankless system?

During our free on-site evaluation, we check three key factors: (1) Gas or electrical capacity—most gas models need a ¾-inch gas line and adequate BTU supply; electric models may require 120–200 amps of service. (2) Venting route—condensing gas units use PVC venting that must terminate outdoors; electric models need no vent. (3) Water line access—cold-water inlet and hot-water outlet lines must be reachable within a few feet of the mounting location. Almost every Sevierville residence can be adapted, but older cabins may need an electrical service upgrade or a new gas drop, which we can coordinate for you.

What size or flow rate should I choose for my household?

Sizing is based on the peak gallons-per-minute (GPM) you’ll need. For example, a typical Sevierville family of four using one shower (2.5 GPM) and a washing machine (2 GPM) simultaneously needs roughly 5–6 GPM at a 70 °F temperature rise (from 50 °F inlet water to 120 °F). Larger vacation cabins with multiple baths might require 9–11 GPM or two units in parallel. We calculate load, temperature rise, and incoming water temperature to recommend the proper model so you always have consistent hot water without overspending on an oversized heater.

How long does installation take, and what should I expect on installation day?

Most residential swaps from a tank to a tankless unit take 4–7 hours. We start by safely draining and removing your old tank, then mount the new heater on a wall bracket. Next we upgrade gas, electric, or water lines as needed and install condensate and vent piping to current code. After pressure testing for leaks, we program the digital controller, flush the system, and walk you through user settings. We always haul away the old tank and leave the workspace clean. Larger custom installs or multiple-unit setups may expand the timeline to one full day.

Are there incentives or rebates available in Sevier County or Tennessee for going tankless?

Yes. As of 2024, TVA’s EnergyRight program offers up to a $200 rebate on qualifying ENERGY STAR® gas or electric tankless heaters installed by a licensed pro. If you switch from an electric storage tank to a high-efficiency gas tankless model, Sevier County Utility District provides an additional $100 bill credit. Federal tax credits under the Inflation Reduction Act cover 30 % of project cost, up to $600, for units with a ≥0.95 UEF. We handle all paperwork and will apply eligible credits to your final invoice.

What maintenance does a tankless water heater require and how do operating costs compare to a traditional tank?

Operating costs are typically 15–40 % lower because the unit only heats water when you open a tap, eliminating standby losses. Annual maintenance is straightforward: we flush the heat exchanger with food-grade vinegar to remove mineral scale, inspect the combustion fan (gas models), and clean the inlet filter. The service takes about 45 minutes and costs far less than a tank’s anode-rod replacement or early tank-corrosion failures. Regular maintenance protects your warranty—which can be 12 years on the heat exchanger—and keeps efficiency high for decades.
