FAQs
What advantages does a high-efficiency tankless water heater offer over a traditional storage tank in Jonesborough?
A high-efficiency tankless unit heats water on demand, so it eliminates standby heat loss from a storage tank. That typically cuts water-heating energy use by 25–40 %, lowering monthly utility bills. Because there is no tank, you can enjoy virtually endless hot water—ideal for large families or back-to-back showers. The compact wall-hung design frees up floor space in basements, crawl spaces, or utility closets. Finally, most premium models in the 95 %+ efficiency range qualify for energy-saving rebates from the State of Tennessee or local utilities, improving the return on investment.
Is my Jonesborough home a good candidate for a tankless water-heater installation?
Most homes in the Jonesborough area can be retrofitted successfully. The key factors we evaluate during a free in-home assessment are: (1) Available gas supply or electric service—tankless gas units need a ¾-inch gas line and 120 V outlet; electric models require 150–200 amp service. (2) Venting path—high-efficiency condensing models use PVC venting that can often run through an exterior wall or roof. (3) Water hardness—well water in Washington County may need a scale-reduction filter to protect the heat exchanger. (4) Desired flow rate—the number of simultaneous fixtures you want running determines unit sizing in gallons per minute (GPM). Our licensed plumbers will perform these checks and present options tailored to your home layout and hot-water demand.
How long does a typical tankless installation take and will my hot water be off for long?
A straightforward replacement of a gas or electric tank with a wall-mounted tankless unit usually takes 4–6 hours. More involved projects—such as upgrading gas piping, running a new 120 V circuit, or relocating the water heater—may extend the job to one full day. Your hot water will be turned off only after the old unit is isolated and drained, typically for 2–3 hours. We schedule installations to minimize disruption and always leave you with one operational bathroom at the end of the day.
Will I need to upgrade my gas line or electrical panel for a tankless unit?
Many Jonesborough homes built before the 2000s were piped with ½-inch gas lines sized for 40–50-gallon tanks. High-efficiency tankless models require a higher BTU input (150,000–199,000 BTU). If the existing meter and interior piping cannot deliver adequate volume, we may run a dedicated ¾-inch line from the meter to the water-heater location. For electric tankless systems, each heating module draws 30–40 amps; whole-house units may need three 240 V breakers. If your panel is under 150 amps, a service upgrade might be necessary. Our estimator provides a firm quote that includes any required gas or electrical work so you’re never surprised by add-on costs.
What kind of maintenance does a tankless water heater require?
To keep the heat exchanger operating at peak 95 %+ efficiency and protect your warranty, manufacturers recommend an annual service. Our maintenance visit in Jonesborough includes flushing the unit with a vinegar solution or citric-acid cleaner to remove lime scale, cleaning the inlet screen, checking burner calibration, updating firmware, and verifying proper venting. In areas with hard water, we may install a scale-inhibitor filter and suggest a biannual flush. With regular care, a stainless-steel heat exchanger can last 20–25 years—about twice the life of a conventional tank.
Are there rebates, tax credits, or financing options available locally?
Yes. Homeowners who install an ENERGY STAR®-certified tankless unit with at least 95 % AFUE may qualify for the federal 25C tax credit—30 % of project cost, up to $600. Tennessee’s state EnergyRight program occasionally offers $100–$300 rebates for high-efficiency natural-gas equipment. Atmos Energy and local co-ops in the Jonesborough area have seasonal incentives that cover $150–$400 depending on efficiency rating. We handle all paperwork, provide model numbers, and issue the forms you’ll need at tax time. Affordable monthly financing is also available through our plumbing company’s partner lender, often with 0 % APR for the first 12 months.
