FAQs
What advantages does a tankless water heater offer over a traditional storage-tank unit in Maynardville?
A tankless (on-demand) water heater heats water only when you open a tap, eliminating the standby heat loss that occurs in a storage tank. Most homeowners in Maynardville see energy-use reductions of 25–40 %, which can trim $75–$150 a year from utility bills. You also gain endless hot water, a unit that is roughly the size of a carry-on suitcase (freeing up floor space), and a life expectancy of 20+ years—about double that of a conventional tank. Because the burner or heating elements fire only when needed, tankless systems tend to require less frequent replacement of sacrificial anodes and have lower risk of leaks and flood damage.
How long does a typical tankless water heater installation take in a Maynardville home?
Most residential installations are completed in one working day. Our crew begins by shutting off water, gas or electricity, and removing the old tank (1–2 hours). We then hang and connect the new tankless unit, upsize gas or wiring if needed, and install Category III venting or PVC air intake/exhaust (3–4 hours). Final steps include pressure testing, flushing, and local Union County code inspection (1–2 hours). Homes that need a longer gas line from the meter or relocation of the heater sometimes extend the project to a second day, but we’ll let you know up front after the site visit.
Will a tankless water heater really lower my energy bills?
Yes. According to DOE testing, gas tankless models operate at 0.82–0.98 Energy Factor compared with 0.60–0.65 for gas storage tanks. In practical terms, a family of four in Maynardville that uses about 60 gallons of hot water per day will save roughly 175–200 therms annually, worth $75–$120 at current Atmos Energy gas rates. Electric tankless units show similar percentage savings but are most cost-effective when paired with a time-of-use or solar-assisted electrical system. Because the unit does not cycle 24/7, reduced combustion hours also mean less wear on components and lower carbon emissions.
What size or flow-rate tankless unit should I choose?
Selection is based on two factors: (1) the maximum number of fixtures you expect to run simultaneously and (2) the cold-water inlet temperature in winter. In Maynardville, entering city or well water averages 52–55 °F in January. To supply a typical shower (2.0 gpm) and a washing machine (2.5 gpm) at 120 °F simultaneously, you need a 4.5 gpm rise of 68 °F, so a 9–10 gpm gas unit or a 27 kW electric model is recommended. Smaller households that rarely run more than one fixture at a time can opt for a 6–7 gpm unit. Our technicians perform a free sizing calculation during the estimate to make sure you never run short.
What routine maintenance does a tankless water heater require?
Although tankless systems have fewer corrosion issues than tanks, they still need annual service: (1) Descale the heat exchanger with white vinegar or food-grade citric solution for 30–45 minutes to remove calcium; (2) clean the inlet water filter; (3) inspect burner, igniter, and vent; (4) run a diagnostic self-test. Homes with very hard water (over 10 grains per gallon) should flush every six months or install a water-softening or scale-inhibiting filter. Regular maintenance keeps the heat exchanger efficient and preserves the manufacturer’s 12- or 15-year warranty.
Is Maynardville’s water hardness a concern, and do I need a water softener with a tankless heater?
City of Maynardville Water and most private wells in Union County measure 8–12 grains per gallon (moderately hard). Hard water leaves mineral deposits inside the tankless unit’s narrow water passages, reducing efficiency and triggering over-temperature shutdowns. We strongly recommend installing either a full-house softener or a compact anti-scale cartridge on the heater’s cold-water inlet. The cost is typically $200–$600 and pays back quickly by preventing scale buildup, maintaining high combustion efficiency, and safeguarding your warranty—which often specifies that units damaged by scale are not covered.
