FAQs
How does a tankless water heater work, and why is it more energy-efficient than a traditional tank?
A tankless (on-demand) water heater senses flow when you open a tap, ignites a high-efficiency burner or activates electric heating elements, and heats water as it passes through a heat exchanger. Because it only runs while you’re actually using hot water, it avoids the 24/7 standby losses of a storage tank. ENERGY STAR® models can reach efficiencies of 95 %+ and typically cut water-heating energy use by 25–40 %, translating into lower utility bills and a reduced carbon footprint for Duff homeowners.
Will a tankless unit supply enough hot water for my Duff home?
Yes—provided the unit is sized correctly. Unlike a tank that holds a fixed volume, a tankless heater is rated by flow rate (gallons per minute, or GPM). We calculate the combined flow of the fixtures you’re likely to run at the same time (e.g., shower + kitchen sink). Modern gas condensing units can deliver 8–11 GPM, more than sufficient for most single-family homes. For large households, we can install parallel units or a dedicated point-of-use heater. A pre-installation assessment ensures you’ll never run out of hot water, even during peak demand.
What size tankless water heater do I need?
Sizing is based on two factors: 1) the temperature rise—the difference between incoming groundwater (often ~50 °F in Duff) and your desired outlet temperature (120 °F is standard), and 2) the maximum simultaneous flow rate required. For example, a shower (2.5 GPM) + dishwasher (1 GPM) needs 3.5 GPM at a 70 °F rise. A 160,000 BTU natural gas unit or a 27 kW electric unit would meet that load. During your free consultation we measure groundwater temperature, inventory fixtures, and recommend a model that meets your exact needs while leaving room for future additions.
How long does installation take, and what’s involved in replacing my current water heater?
A straightforward swap generally takes one business day: 1) We drain and remove your existing tank. 2) Gas piping or electrical service is upgraded, if necessary, to supply the higher input rating. 3) We mount the compact tankless unit on the wall, run sealed combustion venting to the exterior, install a condensate drain (for high-efficiency gas models), and connect water lines with isolation valves for easy maintenance. 4) The system is pressure-tested, purged of air, and electronically commissioned. We handle all Duff permitting and code inspections; you’re left with reclaimed floor space and instant hot water.
What is the expected lifespan and what maintenance is required?
Tankless heaters last 20–25 years—roughly double the life of a storage tank—because they avoid constant thermal stress and corrosion. Annual maintenance is simple: flushing the heat exchanger with food-grade vinegar to remove scale, cleaning the inlet filter, and checking the condensate neutralizer (gas units). Our Duff service plan covers these tasks, maintains your warranty, and keeps efficiency at peak levels. Many manufacturers offer 12- to 15-year heat-exchanger warranties when maintenance records are kept.
Are there local incentives or rebates in Duff for installing an energy-efficient tankless water heater?
Yes. Duff residents served by the Tennessee Valley Authority (TVA) may qualify for $200–$500 rebates on ENERGY STAR® gas or electric tankless units through the EnergyRight program. Additionally, the federal Inflation Reduction Act offers a 30 % tax credit, up to $600, for qualifying installations completed in 2024. Our team handles the paperwork, provides AHRI certification numbers, and supplies itemized invoices so you can easily claim both local and federal incentives, maximizing your return on investment.
