FAQs
How does a tankless water heater work and why is it considered energy-smart?
Unlike traditional tanks that keep 40–50 gallons constantly hot, a tankless (on-demand) unit heats water only when a tap is opened. A flow sensor signals a high-efficiency gas burner or electric element to fire up, sending water through a heat exchanger and out to your fixtures within seconds. Because there is no standby tank to re-heat, the U.S. DOE estimates energy use is cut 24–34 % in typical homes. Our Energy-Smart models sold in Farragut are condensing units that reclaim extra exhaust heat, pushing efficiencies to 95–98 % and qualifying for federal tax credits.
What size tankless unit do I need for my Farragut home?
Sizing is based on two factors: (1) combined flow rate of fixtures you may run simultaneously, and (2) the temperature rise needed (incoming water temp to desired 120 °F). In Farragut, groundwater averages 55–60 °F, so you’ll need roughly a 60 °F rise. Add up fixture flow rates—for example, shower (2.0 gpm) + dishwasher (1.5 gpm) + sink (1.0 gpm) = 4.5 gpm. A 180–199 k BTU gas unit delivering 5–7 gpm at a 60 °F rise would cover most 2- to 3-bath homes. Larger households or luxury master baths may require a second unit or a commercial-grade model. We provide a free in-home assessment to calculate the exact capacity.
How much can I save on utility bills with a tankless water heater?
Savings depend on hot-water usage and current fuel costs, but our customers in the Knoxville–Farragut area typically report 20–40 % lower gas bills compared with a standard 0.60 EF tank. At today’s gas rates, that’s $70–$150 per year for a family of four. Electric tank-to-tankless swaps save even more because electric tanks are less efficient to begin with. Add federal tax credits up to $600 and potential TVA energy rebates, and most installations pay for themselves in 4–7 years.
Will a tankless water heater provide enough hot water for multiple fixtures running at once?
Yes—provided the unit is sized correctly. A tankless heater supplies a continuous stream, limited only by its maximum flow capacity. When sized for your peak demand (see sizing FAQ), two showers and a washing machine can run without the temperature dip you often feel when a conventional tank runs out. For very large homes or simultaneous spa-style loads, we can install a parallel manifold system with two units that automatically stage on and off as demand changes.
What is involved in the installation process in Farragut, and do you handle permits and code requirements?
Installation usually takes one day. We remove your old tank, mount the new wall-hung unit, run Category IV stainless venting, upsize gas lines if necessary, and add an outdoor condensate drain or pump. Farragut follows the 2018 IRC and IFGC, which require combustion-air clearance, combustion venting, and backflow protection. Our licensed, bonded technicians pull the required Town of Farragut permit, schedule the inspection, and provide you with a certificate of completion for your records and manufacturer warranty.
How much maintenance does a tankless system require, and what is the expected lifespan?
Plan on an annual 45-minute service: flushing the heat exchanger with a vinegar solution to remove scale, cleaning the inlet filter, and checking vent seals. Farragut’s moderately hard water (5–7 grains per gallon) makes descaling important; neglect can lower efficiency and void warranties. With routine maintenance, gas tankless units last 20–25 years—roughly double the life of a storage tank. We offer an Energy-Smart Maintenance Plan that includes yearly service reminders, discounted parts, and priority scheduling.
