FAQs
How does a tankless water heater save energy compared to a traditional storage tank?
Tankless units heat water only when you open a tap, so they avoid the 24-hour standby heat loss that occurs in a storage tank. The U.S. Department of Energy estimates energy savings of 24–34 % for homes that use up to 41 gallons of hot water a day, and 8–14 % for heavier-use households. Because less fuel is wasted, you see lower monthly utility bills and a reduced carbon footprint.
What size tankless water heater do I need for my Harriman home?
Sizing is based on two factors: (1) the total flow rate of fixtures you want to run at once, measured in gallons per minute (GPM), and (2) the temperature rise between the incoming cold water and your desired hot-water set point. In Harriman, incoming water averages 50–55 °F in winter, so to reach 120 °F you need a 65–70 °F rise. Most three-bedroom homes that plan to run two showers and a dishwasher simultaneously need a unit rated for 7–9 GPM at that rise. Our technicians perform a detailed load calculation during your estimate to recommend the right model.
Will a tankless water heater keep up during Harriman’s cold winters?
Yes. Modern gas-fired and electric tankless heaters automatically modulate burner or element output to match colder incoming water. Flow rate does drop slightly in winter, but correct sizing ensures you still get continuous hot water. We also offer recirculation pumps and mixing valves to further stabilize temperatures on frigid mornings.
Are there rebates or tax credits for installing an energy-efficient tankless unit in Harriman?
Absolutely. Through 2032, the federal Energy Efficient Home Improvement Credit covers 30 % of the installed cost, up to $600. Many Harriman-area customers also qualify for Tennessee Valley Authority (TVA) EnergyRight rebates of $150–$300 on qualifying gas models, plus possible incentives from local utilities such as Harriman Utility Board. We handle all paperwork to make sure you receive every available dollar.
How long does installation take and will I be without hot water?
A straightforward replacement of a gas tank with a gas tankless unit typically takes 4–6 hours. Converting from electric to gas or relocating the heater may extend the job to a full day because we have to run gas, venting, or larger electrical circuits. You will be without hot water only during the actual switchover, usually two hours or less. We schedule installations at your convenience to minimize disruption.
What maintenance do tankless water heaters require, and how long do they last?
Plan on an annual flush and descaling to remove mineral buildup, especially with Harriman’s moderately hard water. Our service includes cleaning the combustion chamber, checking the heat exchanger, and updating firmware on smart models. With regular maintenance, a quality tankless unit can last 20+ years—roughly twice the life expectancy of a conventional tank—so your long-term savings continue well beyond the payback period.
