FAQs
How does a tankless water heater work and why is it a good option for Ten Mile homes?
A tankless (on-demand) water heater senses water flow and instantly activates a high-output heat exchanger—either gas-fired or electric—to raise the water temperature as it passes through the unit. Because it heats only the water you use, it eliminates standby losses associated with storage tanks. In a moderate-climate area like Ten Mile, incoming ground-water temperatures are rarely extreme, so the heater can reach setpoint quickly and operate very efficiently. Homeowners typically see energy-use reductions of 20–40 % and enjoy an endless supply of hot water without the risk of tank leaks.
Is a tankless system compatible with Ten Mile’s water quality and plumbing codes?
Yes. Most homes here are supplied by either the Watts Bar Utility District or a private well. Municipal water in Ten Mile is considered moderately hard (5–7 gpg), which is well within the tolerance range of modern tankless units. If you’re on a well with higher hardness or iron, we simply add a sediment filter or softener to protect the heat exchanger. Ten Mile follows the 2021 International Residential Code (IRC) and the National Fuel Gas Code; our licensed plumbers secure all required permits and handle venting clearances, gas line sizing, and electrical disconnects to ensure a fully code-compliant installation.
What size tankless water heater do I need for my household?
Sizing is based on two factors: (1) your peak hot-water demand in gallons per minute (GPM) and (2) the temperature rise needed to reach your desired output (usually 120 °F). In Ten Mile, incoming water averages 58–60 °F, so you need about a 60 °F rise. A typical three-bathroom home with two simultaneous showers and a dishwasher running might require 6–8 GPM at that rise, which translates to a 180,000 BTU gas unit or a 27-kW electric model. Smaller households or those who use low-flow fixtures can often use 140,000 BTU or 18-kW units. During your free estimate we measure actual fixture flow rates and recommend the exact model to match your lifestyle.
What is involved in the installation process and how long will it take?
Most retrofits are completed in one day. We start by isolating and draining your old tank, then mount the compact tankless unit on the wall—usually in the same utility area to minimize piping runs. Next, we upsize or re-route the gas line (for gas models), install stainless-steel concentric venting through an exterior wall or roof, add a condensate drain if the unit is condensing, and connect water and electrical lines. Finally, we flush the system, program the controller, and show you how to use it. All debris is hauled away, and you’ll have hot water before we leave.
What maintenance does a tankless water heater require?
Routine care is simple. Once a year we recommend: 1) flushing the heat exchanger with a 5-gallon vinegar solution to remove mineral scale; 2) cleaning the inlet screen filter; 3) checking the condensate trap and venting for obstructions; and 4) running a diagnostic test on the control board. These steps take about an hour and can be done by the homeowner or scheduled as part of our annual service plan. With proper maintenance, a quality tankless unit should last 20–25 years—roughly double the lifespan of a conventional tank.
Are there rebates or incentives for installing a tankless water heater in Ten Mile?
Yes. TVA’s EnergyRight program currently offers a $150 credit for ENERGY STAR® certified gas tankless water heaters installed by a Quality Contractor Network (QCN) member—our company qualifies. In addition, the federal Inflation Reduction Act provides a tax credit of 30 % of the project cost, up to $600, for high-efficiency gas units and up to $2,000 for qualifying electric heat-pump water heaters. We supply all documentation and will even file the TVA rebate paperwork on your behalf to maximize your savings.
