FAQs
How does a tankless water heater save energy compared to a traditional storage-tank model?
Standard tanks keep 40–80 gallons of water hot all day, losing heat through the tank walls and flue. A gas or electric tankless unit heats water only when a tap is opened, so there is no standby loss. The U.S. Department of Energy estimates that households using 41 gallons or less of hot water daily can cut water-heating energy use by 24–34 %, and even heavy-use homes still save 8–14 %. Fayetteville customers also benefit from fast recovery times, meaning less wasted water while you wait for hot water to arrive.
What size tankless unit do I need for my Fayetteville home, and how is it determined?
Proper sizing is based on two numbers: 1. Peak flow rate – the total gallons per minute (GPM) your fixtures might demand at once (shower ≈ 2.0 GPM, kitchen sink ≈ 1.5 GPM, washer ≈ 2.5 GPM, etc.). 2. Temperature rise – the difference between incoming cold-water temperature and your desired hot-water setpoint. In Fayetteville ground-water averages 60–65 °F, so to reach 120 °F you need roughly a 55 °F rise. Multiply the desired flow rates, then match to a heater that can deliver that GPM at a 55 °F rise. A typical 3-bathroom home usually needs a 7–9 GPM gas unit or a 5–7 GPM electric unit. Our technicians perform an on-site audit to confirm the exact model that meets both your demand and the local gas/electric service capacity.
Are there rebates or tax incentives available in Fayetteville or North Carolina for installing an energy-efficient tankless water heater?
Yes. As of 2024, North Carolina residents can claim a 30 % federal tax credit (up to $600) on qualifying ENERGY STAR® natural-gas tankless models under the Inflation Reduction Act. Duke Energy Progress and Piedmont Natural Gas also periodically offer $150–$350 rebates for high-efficiency installations. The City of Fayetteville’s PWC has a low-interest loan program for energy-saving upgrades. Programs change yearly, so we handle all paperwork and will apply eligible rebates to your invoice upfront whenever possible.
How long does a typical tankless water heater installation take, and will my water service be interrupted?
Most residential replacements are completed in one day—about 6–8 hours for gas and 4–6 hours for electric models. During the swap-over, water is off for 1–2 hours and gas/electric is off for 30–60 minutes while we reroute piping, install venting, and test the new unit. If we are moving the heater to a new location or upsizing the gas line, add a few hours. We schedule work around your routine and always leave at least one bathroom usable until final tie-in.
What maintenance does a tankless water heater require, and can I do it myself?
Tankless units have no anode rod to replace, but they must be descaled yearly in areas with moderate to hard water—Cumberland County averages 5–7 grains per gallon. Maintenance involves closing service valves, circulating a white-vinegar or manufacturer-approved cleaner through the heat exchanger for 30–45 minutes, cleaning the inlet filter, and then flushing with fresh water. Handy homeowners can do this with a pump kit, but most customers schedule our $99 annual tune-up, which also includes combustion analysis, vent inspection, and firmware updates (for Wi-Fi models). Regular service preserves the warranty and keeps efficiency high.
How much does it cost to install a tankless water heater in Fayetteville, and what factors affect the price?
Installed prices typically range from $3,000–$4,500 for a whole-home natural-gas unit and $2,200–$3,500 for an electric model. The final cost depends on: • Capacity (GPM) and efficiency rating (UEF) • Whether you need a new dedicated gas line or upgraded electric circuit/breaker • Venting requirements—stainless, PVC, or concentric direct-vent • Relocating the heater for code clearance or convenience • Optional add-ons like a recirculation pump or Wi-Fi control • Available rebates and tax credits We provide free on-site estimates outlining each cost component and the estimated annual energy savings so you can make an informed decision.
