FAQs

How long does a tankless water heater installation typically take in Farragut?

Most residential installations in Farragut can be completed in one business day (6–8 hours). This includes removing the old tank-type unit, upgrading gas or electrical lines if needed, mounting the new tankless heater, venting it to code, and performing a final start-up and safety check. Complex situations—such as relocating the unit or upsizing gas service—may extend the job to two days.

Do I need to upgrade my gas or electrical service before installing a tankless unit?

Possibly. Gas-fired tankless models require a higher BTU input (120,000–199,000 BTU) than most storage tanks, so we verify that your home’s gas meter and supply line can deliver the additional volume and pressure. Electric tankless units demand 120–150 amps of dedicated 240-V capacity. During our free on-site estimate, we measure your existing service and let you know if an upgrade is necessary before installation.

What is the average cost of a tankless water heater installation in the Farragut area?

For a typical 3-bedroom home, a professionally installed gas tankless system ranges from $3,200 to $4,800, including the heater, venting materials, gas line modifications, and labor. Electric units run $2,200–$3,500, but may require a panel upgrade that can add $800–$1,200. We provide a firm, itemized quote after evaluating your site, fuel source, and hot-water demand.

Will a tankless water heater really save me money on energy bills?

Yes. Because tankless systems heat water only when you open a tap, they eliminate standby losses associated with storing 40–50 gallons of hot water. In Farragut’s climate, ENERGY STAR®–rated gas models typically cut water-heating costs 25–40 % compared to a standard tank, yielding $80–$120 in annual savings for a family of four. Electric unit savings depend on your usage pattern and local utility rates.

How does the hard water in Farragut affect maintenance of a tankless heater?

Knox County water measures 4–6 grains per gallon—classified as moderately hard. Over time, mineral buildup can reduce heat-exchanger efficiency. We install an isolation valve kit with every heater so you can flush the unit with white vinegar or a manufacturer-approved descaler once a year. A 30-minute flush keeps warranty coverage intact and extends service life well beyond the 15-year average.

What warranty and post-installation support do you provide?

All major brands we install (Rinnai, Navien, Rheem) carry a 12- or 15-year limited warranty on the heat exchanger, 5 years on parts, and 1 year on labor. Our company adds a 2-year workmanship guarantee, meaning we’ll address any installation-related issue at no charge. We also offer optional annual maintenance plans that include system flushing, filter cleaning, and a full safety inspection.
