FAQs
How does a tankless water heater provide endless hot water?
Unlike traditional storage tanks that continually re-heat 40–50 gallons of water, a tankless (on-demand) unit contains a powerful gas burner or electric element that activates the moment you open a hot-water tap. Cold water passes through a heat exchanger and is delivered at the set temperature within seconds. Because the unit keeps heating as long as water flows, you never "run out"—you get a continuous supply until you shut the tap off.
What size tankless water heater do I need for my Rogersville home?
Sizing is based on two factors: 1) the maximum number of fixtures you might use at one time (showers, dishwasher, washing machine, etc.), and 2) the temperature rise required—how many degrees the incoming water must be heated to reach your desired output (usually around a 60–70 °F rise in Rogersville). We calculate total flow rate in gallons per minute (GPM). For example, two simultaneous showers and a sink might need 6–7 GPM. During our in-home assessment we measure your incoming water temperature, discuss usage habits, and recommend the properly sized gas or electric model so you always have adequate hot water without overspending on capacity.
Are tankless water heaters energy-efficient and how much can I save?
Yes. Because they heat water only when you need it, tankless units eliminate the standby heat losses that storage tanks experience while keeping 40–50 gallons hot 24/7. ENERGY STAR® reports savings of 24–34 % for families using 41 gallons per day and 8–14 % for higher-use households. In real dollars, Rogersville homeowners typically save $70–$120 per year on utility bills, and high-efficiency condensing models can boost savings even further. Lower energy use also means reduced carbon emissions, making tankless a greener option.
How long does installation take and what disruptions should I expect?
A straightforward replacement of a gas tank with a gas tankless unit usually takes 4–6 hours. If we need to upsize gas lines, add venting, or convert from electric, the job can extend to a full day. Our licensed technicians handle permits, remove and recycle your old heater, install new water and gas connections, mount or hang the unit, and test for leaks and proper combustion. Water will be off for 1–3 hours; we always schedule at your convenience and leave the workspace clean.
What maintenance does a tankless unit require and can you handle it?
To maintain efficiency and honor the manufacturer’s warranty, a yearly service is recommended. We flush the heat exchanger with a mild vinegar solution to remove mineral scale, inspect the burner, clean the air intake filter, and run a system diagnostic. Hard-water areas around Rogersville may need service every 6–9 months. Endless Hot Water Plumbing offers affordable maintenance plans and can notify you when it’s time for service, ensuring peak performance and long equipment life (20+ years).
Are there rebates or incentives for installing a tankless water heater in Rogersville?
Yes. Many Rogersville utility customers qualify for rebates of $150–$350 for ENERGY STAR® certified gas tankless models. Federal tax credits under the Inflation Reduction Act offer up to 30 % of the installed cost (capped at $600 for non-condensing and $2,000 for qualifying high-efficiency condensing units). We handle the paperwork, provide proof of purchase, and guide you through claiming any state or local incentives so you get the maximum savings possible.
