FAQs
What are the main advantages of switching to a tankless water heater in Tazewell?
Tankless (on-demand) heaters deliver hot water only when you open a tap, eliminating standby energy losses from a storage tank. Homeowners typically see energy-bill savings of 20–40 %, unlimited hot water for consecutive showers, and a unit life expectancy of 20+ years—about twice that of traditional tanks. They also free up floor space and greatly reduce the risk of tank leaks that can cause water damage.
How do I determine the correct size (flow rate and temperature rise) for my tankless unit?
Sizing is based on the peak gallons-per-minute (GPM) you need and the temperature rise between Tazewell’s incoming water (about 50 °F in winter, 60 °F in summer) and your desired hot-water temperature (typically 120 °F). Our licensed technicians add up the flow rates of fixtures you might use simultaneously—e.g., a 2.5 GPM shower + 1.5 GPM kitchen sink = 4 GPM—and select a heater that can provide that flow at a 60-70 °F rise. We perform an on-site evaluation to verify gas line capacity or electrical amperage before making a final recommendation.
Will I need any special maintenance for a tankless water heater?
Yes, but it’s straightforward. Mineral buildup can reduce efficiency, especially with Tazewell’s moderately hard water. We recommend a professional descaling flush once a year (or every 6 months if hardness exceeds 10 grains per gallon). The service takes about an hour and involves circulating a food-grade vinegar solution through the heat exchanger. We also clean the inlet screen filter and run a full diagnostic to ensure peak performance.
Can a tankless system work with my existing plumbing, gas, or electrical service?
In most homes the answer is yes, but some adjustments may be necessary. Gas models often require a ¾-inch gas line and Category III stainless venting; we’ll verify pressure and install new vent pipe if needed. Electric units demand 120–150 amps of dedicated service, so we’ll check your panel capacity. Plumbing connections tie into your existing hot and cold lines, and we add isolation valves to simplify future maintenance. All work is completed to Virginia plumbing and fuel-gas codes, and we pull the required local permits.
How long does a typical installation take, and will I be without water during that time?
Most residential installs in Tazewell are completed in one day—about 4–6 hours for a straightforward replacement in the same location, or up to 8 hours if we need to reroute venting or upgrade gas piping. Your water is usually shut off for only 1–2 hours while we disconnect the old tank, mount the new unit, and pressure-test the lines. We schedule installations at your convenience and restore water service as quickly as safety allows.
Are there rebates or incentives available in Tazewell for installing a high-efficiency tankless heater?
Yes. Appalachian Power customers can qualify for a $400 energy-efficiency rebate on qualifying ENERGY STAR® gas units. If you choose an electric model, the TVA EnergyRight program offers $200–$300 incentives. Federal tax credits of 30 % (up to $600) are also available through 2032 for units with a Uniform Energy Factor (UEF) of 0.95 or higher. Our office handles the paperwork and provides the model numbers, AHRI certificates, and proof-of-installation documents you need to claim these savings.
