FAQs
How does a tankless water heater give me "endless" hot water, and is it truly continuous?
Unlike a storage tank that heats a finite supply, a tankless (on-demand) heater uses high-output burners or electric elements to heat water only when a hot-water tap opens. Cold water flows across a heat exchanger and exits at the set temperature seconds later. As long as the unit’s maximum flow rate is not exceeded and gas/electric supply is uninterrupted, it can produce hot water indefinitely, so multiple showers or a long soak won’t run a tank dry.
What size tankless unit do I need for my Bluff City home?
Sizing is based on peak demand, measured in gallons per minute (GPM), and the temperature rise needed. In Bluff City, incoming groundwater averages about 55 °F. If you want 120 °F water, you need a 65 °F rise. Add up the flow rates of appliances you may run at once—for example, two showers (2.0 GPM each) and a dishwasher (1.5 GPM) equals 5.5 GPM. You’d choose a unit rated for at least 6 GPM at a 65 °F rise. Gas units usually handle higher GPM than electric models, so whole-house applications typically use natural gas or propane.
Should I choose a gas or electric tankless water heater for this area?
Natural gas or propane tankless heaters are most common in Bluff City because they deliver higher flow rates (7–11 GPM) and are cost-effective where gas is available. Electric models work well for small homes, point-of-use installations, or properties without gas service, but they may require heavy-gauge wiring and 120–150 amp breakers. We’ll evaluate your home’s gas line capacity or electrical panel during the estimate to recommend the best option.
What does installation cost, and will a tankless heater save me money?
Installed prices in Bluff City typically run $3,000–$4,500 for a gas unit and $2,200–$3,200 for an electric unit, depending on model, venting requirements, gas line upsizing, and any electrical upgrades. While the upfront cost is higher than a tank, Energy Star–rated gas units are 24–34 % more efficient, and electric units approach 99 % efficiency. Most homeowners see energy savings of $80–$120 per year, with payback in 6–8 years. Tennessee offers occasional rebates, and federal tax credits of up to 30 % (max $600) are available for qualifying models.
What maintenance does a tankless water heater require?
Annual service keeps performance high. We flush the heat exchanger with a vinegar or citric-acid solution to remove mineral scale, clean the inlet screen, inspect the burner or elements, and verify gas pressure or amperage draw. Bluff City’s water hardness averages 7–9 grains per gallon—borderline for scale—so adding a sediment filter or a small scale-inhibiting cartridge is wise. With proper maintenance, a tankless heater will last 20+ years, roughly double the life of a storage tank.
Do I need permits or code inspections in Bluff City before installation?
Yes. Sullivan County and the City of Bluff City both enforce the 2018 IRC and IFGC. A plumbing/mechanical permit is required for gas or electric tankless replacements or new installs. Gas models also need venting that meets the manufacturer’s UL listing, and electric units must have dedicated breakers sized to NEC standards. Endless Hot Water Plumbing pulls all permits, schedules city or county inspections, and provides you with the final approval paperwork, so you stay fully code-compliant and eligible for warranty coverage.
