FAQs
How does a tankless water heater provide “endless” hot water?
Unlike a storage-tank heater that reheats 40–50 gallons over and over, a tankless unit uses powerful gas burners or electric elements that fire up the moment water starts flowing. Cold water passes through a heat exchanger, is instantly heated to the set temperature, and continues to be heated as long as the tap is open. Because there is no finite tank to empty, you never “run out” of hot water—making it ideal for families who do back-to-back showers, laundry and dishwashing in the same morning.
Is a tankless system a good fit for Greeneville’s climate and water quality?
Yes. Our incoming winter water temperature in Greeneville averages 48–52 °F, which is well within the performance range of modern gas and electric tankless models. Local water is moderately hard, so we recommend installing an inline sediment filter and scheduling an annual descaling—simple steps that keep the heat exchanger clean and efficient. Because the climate is relatively mild, exterior-mount units with freeze-protection work well, while interior units need only standard venting and condensate drains.
What size tankless water heater do I need for my Greeneville home?
Sizing is based on simultaneous demand in gallons per minute (GPM) and the required temperature rise (difference between incoming and desired hot-water temperature). A typical Greeneville household that wants to run two showers (2.0 GPM each) and a dishwasher (1.5 GPM) at once would need about 5.5 GPM at a 70 °F rise, so a 160,000–199,000 BTU gas unit or a 27 kW electric unit is recommended. During your free estimate, our technicians measure actual fixture flow rates and help you choose the exact model so you never experience a pressure or temperature drop.
How much can I expect to save on energy bills with a tankless water heater?
The U.S. DOE reports that homes using 41 gallons of hot water or less per day can save 24–34 % on water-heating costs; heavier-use homes save 8–14 %. In Greeneville that typically translates to $80–$150 per year compared with a standard gas tank. Because tankless units last 20+ years—roughly twice the life of a tank—the long-term savings are even higher. Many qualifying models also carry a 30 % federal tax credit (up to $600) and TVA energy-efficiency rebates when professionally installed.
What is involved in the installation process—do I need permits in Greeneville?
A standard replacement takes 4–6 hours. We disconnect and haul away the old tank, mount the new unit, upsize the gas line or electrical circuit if needed, install stainless-steel or PVC venting, add a condensate drain, and set up water and gas shut-off valves. Greeneville’s Building Department requires a mechanical and (for gas) fuel-gas permit; we handle the paperwork and arrange the inspection. Most homes need no structural changes and minimal drywall repair.
How often does a tankless water heater need maintenance and what does it involve?
Routine maintenance is simple: 1) Flush the heat exchanger with food-grade vinegar or a citric-acid solution once a year to remove mineral scale; 2) Clean the inlet screen filter every 6–12 months; 3) Check venting, gas pressure and condensate drain annually. Our Endless Hot Water Service Plan includes all of the above plus priority scheduling and parts discounts. Regular upkeep protects your warranty, maintains 95 + % efficiency and extends unit life well beyond 20 years.
