FAQs
What are the main advantages of switching to a tankless water heater in Farragut?
Tankless units heat water on demand, so you never run out of hot water and you avoid standby heat loss common with storage tanks. Most homes that upgrade see energy-bill savings of 20-40 %, longer appliance life (20+ years vs. 10-15 for a tank), and valuable space gains because the wall-mounted unit is much smaller. In Farragut’s humid climate, tankless models also reduce the risk of tank corrosion and leaking, which helps protect floors and finished basements.
How do I determine the correct size (flow rate and BTU) for my household?
Sizing is based on simultaneous demand—how many fixtures you want to run at once—and incoming groundwater temperature, which averages 55-60 °F in East Tennessee. Our licensed plumbers calculate the required gallons per minute (GPM) for peak use (e.g., shower + dishwasher) and match it to a unit with sufficient BTU output to raise water to 120 °F. A typical 2-bath home needs 7-9 GPM, while larger homes with soaking tubs may need 11-15 GPM or multiple units.
Will my home’s gas or electrical service need upgrading for a tankless heater?
Possibly. High-efficiency gas models often require a ¾-in. gas line and a vent upgrade to 4-in. stainless or PVC. Electric tankless units draw 120-150 amps, so older 100-amp panels rarely have capacity. During our estimate, we inspect gas piping, meter size, vent paths, and breaker panels, then give you a firm quote that includes any utility upgrades needed to meet City of Farragut and Knox County codes.
How long does installation take, and will I be without hot water?
Most replacements are completed in one day. We shut off the old tank in the morning, mount and pipe the new unit, run venting (or chase electrical conductors), perform gas-pressure or load testing, and file the permit with the county inspector. You may be without hot water for 4-6 hours, but we coordinate the changeover so you have service again before evening.
Are there rebates or tax incentives for tankless water heaters in Farragut?
Yes. Tennessee Valley Authority (TVA) often offers $200-$400 rebates for ENERGY STAR® gas tankless units installed by a Quality Contractor Network (QCN) member—a designation our company holds. The federal Inflation Reduction Act also provides a 30 % tax credit (up to $600) for qualifying high-efficiency water heaters placed in service through 2032. We supply all rebate forms and AHRI certificates so you can claim every available incentive.
What maintenance does a tankless unit need, and how long will it last?
Annual service by a licensed plumber is recommended: we descale the heat exchanger with food-grade vinegar, clean the combustion fan, inspect the burner, and check error codes. In Farragut’s moderately hard water (7-10 grains per gallon), flushing prevents mineral buildup that can trigger overheating. With regular maintenance, today’s stainless-steel heat exchangers are warrantied for 15 years and typically last 20-25 years, twice the lifespan of a traditional tank heater.
