FAQs
What are the main benefits of installing a tankless (on-demand) water heater for my Fayetteville home?
A tankless unit heats water only when you open a tap, so it eliminates standby heat loss, delivers virtually endless hot water, frees up floor space, and typically lasts 18–20 years—about twice as long as a storage tank. Because Fayetteville’s climate has moderate groundwater temperatures, tankless heaters reach set temperature quickly, improving efficiency and lowering utility bills by 20–40 % compared with a conventional tank.
How much should I budget for a professional tankless water heater installation in Fayetteville?
Installed prices in the Fayetteville area generally range from $2,800 to $4,800 for a whole-home gas unit and $2,200 to $3,800 for an electric model. The total depends on capacity (GPM rating), gas line or electrical upgrades, venting requirements, and any code-mandated permits. We provide free on-site evaluations and a firm, line-item quote so you know exact costs before work begins. Local utility rebates (currently up to $300 from Black Hills Energy) and federal tax credits can reduce your net investment.
How do I choose the right size (GPM) tankless water heater?
Sizing is based on two numbers: the maximum flow rate of fixtures you may run simultaneously and the temperature rise needed (difference between incoming water and desired hot-water temperature). For most Fayetteville homes, incoming water averages 55–60 °F. If you want 120 °F water, you need a 60–65 °F rise. Add the flow rates of appliances you use at once—for example, a shower (2.0 GPM) + dishwasher (1.5 GPM) = 3.5 GPM. We calculate your peak demand during the estimate visit and recommend a unit, typically 6–9 GPM for a three-bath house.
How long will the installation take and will I be without hot water?
A straightforward replacement of a gas tank with a gas tankless unit normally takes 6–8 hours. Converting from electric to gas or relocating the heater can extend the job to 1–1½ days. You’ll be without hot water only during the final tie-in (1–2 hours). We schedule installations at your convenience and always leave one bathroom cold-water line active so toilets and sinks remain functional.
Do I need permits or inspections for a tankless water heater in Fayetteville?
Yes. The City of Fayetteville requires plumbing and, for gas units, mechanical permits. Our licensed plumbers pull all necessary permits, coordinate with city inspectors, and ensure the installation meets Arkansas Mechanical Code, vent-clearance rules, and combustion-air requirements. You receive a copy of the passed inspection for your records, which also protects manufacturer warranty coverage.
What maintenance does a tankless heater require and do you provide it?
Manufacturers recommend an annual inspection and descaling (flushing) to remove mineral buildup, especially with Fayetteville’s moderately hard water. The service includes checking burner or heating elements, cleaning the inlet filter, verifying vent integrity, and updating firmware on smart models. We offer affordable maintenance plans that include the annual flush, priority scheduling, and extended labor warranty—helping your unit run efficiently and stay under warranty for up to 15 years.
