FAQs
What are the main advantages of switching to a tankless water heater in La Follette?
Tankless (on-demand) water heaters heat water only when you open a tap, eliminating stand-by heat loss from a storage tank. This can trim 20–40 % off your water-heating bill, give you virtually endless hot water, free up valuable floor space, and typically last 18–20 years—almost twice the life of a conventional tank. Because our region’s groundwater temperature is moderate, tankless units perform very efficiently in La Follette and may qualify for local utility rebates and federal tax credits.
How do I determine the correct size tankless unit for my home?
Sizing is based on two factors: peak hot-water demand (measured in gallons per minute, or GPM) and the temperature rise needed to reach 120 °F. In La Follette, incoming water is usually around 55 °F, so you need a 65 °F rise. Add up the flow rates of fixtures you might use simultaneously—for example, a shower (2.0 GPM) plus a dishwasher (1.5 GPM) equals 3.5 GPM. A typical three-bedroom, two-bath home often needs a 7–9 GPM gas unit or a 24–27 kW electric unit. Our technicians perform a free load calculation on-site to ensure the unit we install keeps up with your household’s real-world demand.
How long does a professional tankless water heater installation take, and will I be without hot water?
Most straightforward replacements are completed within 4–6 hours. If we need to upsize a gas line, run new venting, or upgrade an electrical circuit, the visit can run 6–8 hours. You’ll be without hot water only on the day of the installation—usually no more than half a day. We schedule installations at a time that minimizes inconvenience and haul away your old tank at no extra charge.
Do I need a permit for a tankless water heater install in La Follette, and who handles it?
Yes. Campbell County and the City of La Follette require plumbing and (if gas-fired) mechanical permits, along with a final inspection. As a licensed and insured plumbing contractor, we secure all necessary permits, coordinate any utility shut-offs, and arrange the inspection, so you don’t have to wrestle with paperwork or code requirements.
What maintenance does a tankless water heater require?
Unlike a tank that can rust out, a tankless unit mainly needs an annual flush with a vinegar or descaling solution to remove mineral buildup—especially important with our moderately hard water. We also clean the inlet screen and inspect the vent and gas-pressure settings. Homeowners can handle flushing with an inexpensive pump kit, or you can enroll in our yearly maintenance plan, which includes the flush, a multi-point safety check, and priority service discounts. With proper upkeep, your unit can deliver reliable hot water for two decades.
What does it cost to install a tankless water heater in the La Follette area, and are rebates available?
Installed prices vary with fuel type, brand, and any line upgrades. A whole-home gas unit typically runs $3,200–$4,800, while an electric model starts around $2,000. Costs rise if we must extend a gas line, add Category III venting, or upgrade your electrical panel. We offer 0 % financing for up to 12 months, accept all major credit cards, and will help you claim any incentives—currently a federal 30 % tax credit (up to $600) under the Inflation Reduction Act and a TVA energy rebate of $100 for qualifying ENERGY STAR® models.
