FAQs
What are the main benefits of switching to a tankless water heater for my Fayetteville home?
Tankless units heat water on demand, so you never run out of hot water and you eliminate standby heat loss from a storage tank. Homeowners typically see energy-bill savings of 20–40 %, and the compact wall-mounted design frees up floor space. Because the heat exchanger is replaceable, many models last 18–25 years—about twice as long as a conventional tank. They’re also safer: no large tank of stored water means virtually zero risk of catastrophic leaks or tank ruptures.
How long does a professional installation take, and will I be without water?
Most residential installations are completed in one work-day (4–8 hours). We usually shut off water and, if applicable, gas or electricity for 1–2 hours while we remove the old tank, hang the new unit, run venting, and make final connections. We coordinate with you in advance so you can plan around the brief service interruption, and we always test every fixture before we leave.
Do I need to upgrade my gas line or electrical service before installing a tankless heater?
It depends on the model and your existing utilities. Gas-fired units often require a ¾-inch gas line and Category III or IV venting; many older homes in Fayetteville have ½-inch lines that need upsizing. Electric tankless units draw 120–160 A, which can exceed a typical 200-amp service panel. Our licensed plumbers do a site survey, calculate BTU or amp requirements, and tell you whether a line or panel upgrade is necessary before you commit to the project.
How much does a tankless water heater installation cost in the Fayetteville area, and are there rebates?
Installed prices start around $2,800 for a mid-efficiency gas unit and average $3,500–$4,800 for high-efficiency condensing models, including labor, venting, and minor gas-line extensions. Electric units range from $2,200–$3,200 installed. Fayetteville PWC, Ozarks Electric, and some natural-gas utilities periodically offer $150–$400 rebates, and federal tax credits of 30 % (up to $600) are available on Energy Star–certified models through 2032.
How often does a tankless water heater need maintenance, and can your plumbers perform it?
Manufacturers recommend a full service once a year: descaling the heat exchanger with food-grade vinegar, cleaning the inlet screen filter, and checking venting, ignition sensors, and condensate drain. Fayetteville’s water averages 4–6 grains per gallon, which is moderately hard, so annual descaling is important to maintain efficiency and protect your warranty. Our licensed technicians offer affordable maintenance plans and keep digital records to document service history.
What size (gallons-per-minute) tankless unit should I buy for Fayetteville’s climate?
Sizing is based on simultaneous hot-water demand and incoming water temperature. Fayetteville’s winter ground-water temp averages about 55 °F. To supply three fixtures at once—a shower (2 GPM), a dishwasher (1.5 GPM), and a sink (1 GPM)—you need 4.5 GPM at a 65 °F rise, which equals roughly a 180,000 BTU gas unit or a 27 kW electric unit. During summer, warmer inlet temps increase capacity. We perform a whole-home load calculation to recommend the right model so you never experience a drop in water pressure or temperature.
