FAQs
What are the main benefits of switching to a high-efficiency tankless water heater in Farragut?
High-efficiency tankless units heat water on demand, eliminating standby heat loss common with traditional tanks. Customers typically see energy-use reductions of 20–40 %, longer service life (20+ years versus 10–15 for tanks), endless hot-water supply, space savings because the unit mounts on a wall, and lower risk of tank-related leaks and flooding.
How long does a professional tankless water heater installation usually take?
For most Farragut homes, a straightforward replacement of a tank unit with a comparable gas or electric tankless model takes 4–8 hours. The timeframe covers removal of the old heater, mounting the new unit, rerouting water and gas/electrical lines, installing venting (for gas units) and performing start-up testing. If upgrades are needed—such as upsizing gas lines, adding a condensate drain, or relocating the heater—the job can extend to a full day.
Is a tankless unit compatible with the water quality and winter temperatures we have in Farragut?
Yes. Farragut’s water is considered moderately hard, and most modern tankless models include scale-inhibition technology or are easily paired with an in-line filter to protect the heat exchanger. Regarding temperature, reputable units are designed to handle incoming water as cold as 35 °F and still deliver 120 °F output. Proper sizing and, when necessary, freeze-protection kits ensure reliable operation year-round.
How do I determine the right size (flow rate) tankless heater for my household?
Sizing is based on simultaneous demand, measured in gallons per minute (GPM), and the required temperature rise. We calculate your peak demand—e.g., running two showers and a dishwasher might require 7 GPM—and the difference between incoming and desired hot-water temperature. With that data we recommend a unit, often in the 9–11 GPM range for a typical 3- to 4-bath Farragut home. Oversizing wastes money; undersizing results in lukewarm water, so a professional load calculation is essential.
What routine maintenance will my new tankless water heater require?
Plan on an annual service visit. A technician will flush the heat exchanger with a vinegar or citric-acid solution to remove mineral scale, clean the inlet filter, inspect the burner or heating elements, confirm gas-pressure and combustion readings (gas units), and verify software updates. In homes with very hard water, flushing every 6 months is recommended. These services keep efficiency high and preserve the factory warranty.
Are there rebates or incentives for installing a high-efficiency tankless water heater in Farragut?
Yes. Most ENERGY STAR® gas tankless models with ≥0.95 UEF qualify for a federal tax credit of 30 % of project cost, up to $600, through 2032. Knoxville Utilities Board (KUB) sometimes offers bill credits for electric upgrades, and Tennessee Valley Authority (TVA) programs periodically provide $100–$250 rebates for high-efficiency gas units. We handle the paperwork and will alert you to current local incentives at the time of your estimate.
