FAQs
What are the main benefits of installing a tankless water heater in my Evensville home?
A tankless (on-demand) unit heats water only when you open a tap, so it eliminates standby heat loss and can cut water-heating energy use by 25–40 %. Because there’s no storage tank, you also enjoy endless hot water—great for large families or homes with soaking tubs. Tankless heaters mount on a wall, freeing up floor space in basements or utility closets. In addition, most models have replaceable parts and a serviceable heat exchanger, which can extend usable life to 20+ years, nearly double that of many tank units.
How do I determine the correct size (flow rate) for a tankless unit?
Sizing is based on the total flow rate (gallons per minute, GPM) you’ll need at peak demand and the temperature rise between incoming cold water and your desired hot water setpoint. In Evensville, winter ground-water temperatures average 50–55 °F, so achieving a 120 °F outlet temperature requires a 65–70 °F rise. Add up the GPM of fixtures that may run simultaneously—e.g., shower (2.0 GPM) + kitchen sink (1.5 GPM) + washing machine (2.0 GPM) ≈ 5.5 GPM. A gas unit rated around 160,000–180,000 BTU/h or an electric model with at least 24–27 kW may be appropriate. Our technicians perform a load calculation on-site to make sure you select the most efficient model without overspending on capacity.
What is involved in the installation process and how long does it take?
Most residential change-outs are completed in one day. We start by shutting off utilities, draining and removing your old tank, and verifying gas line or electrical service capacity. Tankless heaters require a larger-diameter gas line (usually ¾ inch) or a dedicated high-amperage electric circuit, plus Category III/IV stainless-steel venting for gas units. We mount the new unit on the wall, connect water, gas or power, install condensate and isolation valves, then flush and pressure-test the system. Finally, we program temperature settings, register the warranty, and show you how to operate and maintain the heater. All work complies with Rhea County and Tennessee plumbing/mechanical codes.
Will a tankless heater work with Evensville’s water quality and my existing plumbing?
Yes. Evensville’s municipal supply is considered moderately hard (5–7 grains per gallon). Gas and electric tankless units operate efficiently in this range, but we recommend installing a simple inline scale-inhibition filter or performing an annual vinegar flush to keep the heat exchanger free of mineral buildup. The new heater ties into your current hot- and cold-water lines; no re-piping is needed unless you want a dedicated recirculation loop for instant hot water at remote fixtures. We can also integrate the unit with well systems or booster pumps if your home is outside city limits.
What maintenance does a tankless water heater require?
Plan on a yearly service visit. Our technician will descale the heat exchanger, clean the inlet screen, inspect the burner or heating elements, test the pressure-relief valve, and update firmware when applicable. Homeowners can help by occasionally wiping the air intake screen and checking for error codes on the display. Proper maintenance preserves efficiency, prevents costly heat-exchanger corrosion, and keeps your warranty valid—many manufacturers require documented service records each year.
Are there rebates or tax incentives for installing a high-efficiency tankless unit in Evensville?
Yes. Through the Inflation Reduction Act, qualifying ENERGY STAR gas tankless models with ≥0.95 UEF may earn a federal tax credit of 30 % of project cost up to $600. Tennessee Valley Authority (TVA) occasionally offers additional rebates for electric heat pump water heaters; while gas tankless incentives change periodically, we’ll check current programs on your behalf. Local utility companies sometimes provide $50–$100 bill credits for high-efficiency upgrades. We supply all documentation—model certification, AHRI reference numbers, and installation invoices—so you can easily claim incentives when you file your taxes or rebate forms.
