FAQs
What advantages does a tankless water heater offer compared with a traditional storage tank in Fayetteville?
Tankless units heat water on demand, so you are not paying to keep 40–50 gallons hot all day. That translates to energy savings of 20–40 % for the average Fayetteville household. Because there is no storage tank, you also free up floor space and eliminate the risk of catastrophic tank leaks. In addition, tankless models typically last 18–25 years—roughly twice as long as a tank heater—and most carry longer manufacturer warranties.
How do I determine what size (flow rate) tankless unit my home needs?
Sizing is based on the total gallons per minute (GPM) you want to deliver at peak demand and the temperature rise required for Fayetteville’s groundwater, which averages 55–60 °F. We add up the GPM of fixtures you might use at the same time—e.g., shower (2.0 GPM) + kitchen sink (1.5 GPM) + washing machine (2.0 GPM) = 5.5 GPM. Then we select a unit that can raise incoming water from ~57 °F to 120 °F (63 ° rise) at that flow rate. During our free in-home estimate, our licensed plumber will measure actual flow rates and recommend the right model so you never run out of hot water.
Will my existing gas line, venting, or electrical service need to be upgraded?
Possibly. Most whole-house gas tankless heaters require a ¾-inch gas line and 120 V outlet, and they exhaust through sealed stainless or PVC venting. If your current tank heater is served by a ½-inch line, we may need to upsize a section of pipe to supply the higher BTU load. For electric tankless units, you often need multiple dedicated 240 V breakers. During the site visit we check gas pressure, vent routing options, and panel capacity so you know exactly what modifications—if any—are necessary to meet Fayetteville building code and manufacturer specs.
What does the installation process involve and how long will it take?
On installation day we first shut off and drain your existing water heater, disconnect gas/electric and water lines, and remove the old tank. We then mount the new tankless unit on the wall, run any new gas, water, or condensate lines, install code-approved venting to the exterior, and connect wiring. Finally, we purge air, set the temperature, and run performance checks. A straightforward swap typically takes 4–6 hours; projects requiring gas or electrical upgrades can extend to a full day. You will have hot water again before we leave.
How much does a tankless water heater installation cost in Fayetteville, and are rebates available?
Pricing depends on unit capacity, fuel type, and any piping or venting upgrades. Most residential gas installations fall between $3,200 and $4,800 installed, while electric units range from $2,200 to $3,500. Fayetteville Public Works Commission often offers $200–$350 rebates for ENERGY STAR® gas models, and federal tax credits of 30 % (up to $600) may apply. We provide firm, written quotes beforehand and offer low-interest financing so you can spread the investment over time.
What maintenance is required and how long can I expect my tankless unit to last?
To keep the heat exchanger free of mineral scale, manufacturers recommend an annual flush with a vinegar or citric-acid solution—especially important in Fayetteville’s moderately hard water. Our maintenance plan covers this service, inspects the burner, checks venting, and updates firmware on smart models. With regular maintenance, gas tankless heaters routinely last 20+ years and electric models 15–20 years, delivering reliable, endless hot water for decades.
