FAQs
What are the main advantages of installing a tankless water heater in my New Tazewell home?
Tankless (on-demand) units heat water only when you open a tap, eliminating standby heat loss. This typically delivers energy savings of 20–40 % compared with a standard storage tank. You also gain an unlimited supply of hot water, a compact wall-mounted design that frees up floor space, and a life expectancy of 18–20 years—roughly twice that of a tank heater. In New Tazewell’s moderate climate, these benefits translate to lower monthly utility bills, more usable square footage, and fewer replacement costs over time.
How do I choose the correct size (flow rate) for a tankless water heater?
Sizing is based on simultaneous demand, measured in gallons per minute (GPM), and the required temperature rise (the difference between incoming groundwater and desired hot-water temperature). In New Tazewell, incoming water averages 55–60 °F. If you want 120 °F water, you need a 60–65 °F rise. Add up the flow rates of fixtures you may run at once—for example, a shower (2.0 GPM) + dishwasher (1.5 GPM) = 3.5 GPM. We use manufacturer tables to match this demand to an appropriately powered gas or electric model, ensuring you never run out of hot water even during winter cold snaps.
Will my existing gas, electric, or venting infrastructure support a tankless unit?
Many homes need minor upgrades. Gas models often require a ¾" gas line to deliver 150–200 k Btu/h and a Category III or direct-vent exhaust system. Electric models demand 120–150 A of dedicated 240 V service. During our in-home assessment we measure gas pressure, inspect the panel for available amperage, and map a vent route that meets the 2023 International Fuel Gas Code adopted by Claiborne County. We provide a turnkey quote that includes any necessary piping, breaker, or venting modifications so you know the total cost up front.
What will the installation cost and how quickly will I recoup the investment?
For most New Tazewell residences, installed pricing ranges from $2,900–$4,800 for a high-efficiency gas condensing unit and $2,400–$3,600 for a whole-house electric model. Utility savings average $100–$150 per year on electric water heating and $70–$120 on propane or natural gas, depending on usage. Factoring in the current TVA energy-efficiency rebate ($200 for ENERGY STAR® gas tankless heaters) and reduced maintenance/replacement expenses, typical payback is 6–8 years, after which the energy savings go straight to your pocket.
How long does installation take and will I be without water?
A standard replacement—removing the old tank, installing the tankless unit, upgrading gas/electric service, and setting up venting—takes about one business day (6–8 hours). We coordinate to keep hot-water downtime to a minimum, usually just 2–3 hours. Our technicians protect floors, clean up debris, and conduct a full start-up procedure that includes adjusting flow, testing CO levels, and training you on the digital controller before we leave.
What maintenance does a tankless water heater require and do you offer service plans?
Annual maintenance preserves efficiency and warranty coverage. We flush the heat exchanger with a mild vinegar solution to remove mineral scale (especially important with New Tazewell’s moderately hard water), clean the inlet filter, inspect the burner or elements, and verify combustion settings. Our Plumbing Protection Plan costs $149 per year and includes this flush, priority scheduling, and 10 % off any repairs. With regular care, your tankless unit can reliably serve your household for two decades or more.
