FAQs
What are the main advantages of switching to a tankless water heater in Tazewell?
Tankless units heat water only when you open a tap, so they eliminate standby heat loss that comes with traditional storage tanks. Homeowners in Tazewell typically see energy-use reductions of 20–40 %, limitless hot-water supply for back-to-back showers, and space savings because the wall-hung unit is roughly the size of a small suitcase. With proper maintenance, most quality tankless heaters last 20+ years—about double the life expectancy of a conventional tank.
How long does a professional tankless installation usually take?
Most standard change-outs in single-family homes are completed in one business day (4–8 hours). The timeline covers removal of your old tank, mounting the new unit, running new venting, gas or electrical connections, programming the controller, and performing start-up diagnostics. If significant gas-line, electric-service, or vent modifications are required, the job may extend into a second day, but we’ll let you know after the on-site survey.
Will a tankless system lower my utility bills?
Yes. Because tankless heaters don’t keep 40–50 gallons of water hot 24/7, the U.S. Department of Energy reports savings of 24–34 % for households using 41 gal or less per day and 8–14 % for heavy-use homes. In Tazewell, where winter groundwater temperatures can dip into the 40s, the efficiency benefit is still significant because the burner or heating elements fire only on demand rather than cycling all day.
Do I need to upgrade my gas line or electrical panel?
Possibly. Gas-fired tankless units typically require a ¾-inch gas supply line and higher BTU input (150k–199k) than a standard tank, so undersized lines must be upsized. Electric tankless models often need multiple 40–50 amp breakers and #6 wiring. During our free estimate we measure gas pressure, pipe size, and panel capacity to confirm whether upgrades are necessary and provide a firm quote before we start.
How often should I service a tankless water heater given Tazewell’s water quality?
The calcium hardness in Tazewell’s municipal and well water averages 4–8 grains per gallon, which can create scale inside the heat exchanger. We recommend an annual flush with a vinegar or citric-acid solution to maintain peak efficiency and preserve the warranty. Homes with water softeners can stretch the interval to every 18–24 months. We also clean the intake filter, inspect venting, and run a combustion analysis at each visit.
What size tankless unit do I need for my household?
Sizing is based on peak hot-water demand (gallons per minute, GPM) and incoming water temperature. In Tazewell, winter inlet temps average 45 °F, so a three-bath home that might run two showers (2 GPM each) and a dishwasher (1.5 GPM) simultaneously would need roughly 5.5–6 GPM at a 70 °F rise—equating to a 180k–199k BTU gas unit. We calculate your specific demand during the consultation to prevent undersizing and ensure continuous hot water.
