FAQs

How does a tankless water heater work and what benefits does it offer compared with a traditional storage tank?

A tankless (on-demand) water heater uses high-output gas burners or electric elements to heat water instantly as it passes through a heat exchanger. Because there’s no storage tank, standby heat loss is eliminated, giving you 20–40 % energy savings. Additional benefits include an endless supply of hot water, a much smaller wall-mounted footprint that frees up floor space, and service lives that often exceed 20 years—about double that of a conventional tank.

Is a tankless water heater a good fit for my home in Lenoir City?

Most single-family homes and many condos in Lenoir City can convert to tankless. Key factors are available gas line capacity (or adequate electrical service for whole-house electric models), venting routes to the outdoors, water hardness, and your household’s simultaneous hot-water demand. During our free on-site assessment, we measure flow rates at fixtures, inspect the gas meter or electrical panel, and map out venting options to confirm feasibility before you commit.

What size tankless unit will I need, and how do you determine it?

Sizing is based on two numbers: (1) the maximum gallons per minute (GPM) your family will use at one time and (2) the required temperature rise, which is the difference between groundwater temperature (typically 55–60 °F in Lenoir City) and your desired hot-water temperature (usually 120 °F). We add the flow rates of the fixtures you might run simultaneously—such as a shower (2.0 GPM) plus a dishwasher (1.5 GPM)—and then select a heater that can supply that combined GPM at a 60–65 °F rise. For most three-bedroom homes here, that lands in the 7–9 GPM range.

How long will installation take and will my water service be down for the whole day?

A straightforward replacement of a gas tank with a gas tankless unit typically takes 4–6 hours. Conversions that require upsizing the gas line, adding a condensate drain, or running new venting can extend the job to a full day. Your water will be off only during the final tie-in—usually about 1–2 hours. We schedule work to minimize disruption, and you’ll have cold water available from other lines most of the time.

What maintenance does a tankless water heater require after installation?

To keep your warranty valid and performance high, manufacturers recommend a yearly service: flushing the heat exchanger with a mild descaling solution to remove mineral buildup, cleaning the inlet filter, and checking venting and gas pressures. Lenoir City’s moderately hard water makes this especially important. We offer a low-cost annual maintenance plan that includes all labor, descaler, and a multi-point safety inspection.

How much does a tankless water heater installation cost and are there any rebates available in Lenoir City or Tennessee?

Installed prices vary with capacity, fuel type, and site conditions, but most projects fall between $2,800 and $4,800 for gas units and $2,200–$3,500 for electric units. Tennessee homeowners may qualify for up to $600 in federal energy-efficiency tax credits (IRC 25C) and occasional manufacturer rebates. Some local utilities, such as Lenoir City Utilities Board, also offer bill credits for high-efficiency gas appliances; we’ll prepare all rebate paperwork for you at no charge.
