FAQs
How does a tankless water heater provide endless hot water?
Unlike storage-tank heaters that hold a finite volume of pre-heated water, a tankless (on-demand) unit contains a high-capacity heat exchanger that activates only when a hot-water tap is opened. Cold water travels through the exchanger and is heated instantly—typically within 2–5 seconds—so the supply continues for as long as water flows through the unit. When the tap closes, the burner or electric elements shut off, eliminating stand-by heat loss and ensuring you never “run out” the way you can with a tank.
What size tankless water heater do I need for my Sunbright home?
Sizing is based on two factors: (1) the maximum simultaneous flow rate you expect—calculated by adding the gallons per minute (GPM) requirements of fixtures you might use at the same time—and (2) the required temperature rise, which in Sunbright is usually 70 °F (groundwater averages 55 °F and you typically want 120–125 °F hot water). For most three-bedroom homes, a gas unit rated at 7–9 GPM or an electric unit rated at 5–7 GPM is sufficient. Larger households, spa tubs, or multiple showers may require 10–11 GPM. Our technicians perform a free in-home assessment to confirm the right model before installation.
How energy-efficient are tankless water heaters compared to traditional tanks?
The U.S. Department of Energy reports that gas tankless models are 24–34 % more energy-efficient for homes that use less than 41 gallons per day and 8–14 % more efficient for heavier-use households. Electric tankless units can reach energy factors (EF) of 0.95-0.99. Because there’s no standby loss, annual utility savings in Sunbright typically range from $85–$150 for gas units and $60–$100 for electric models, depending on usage and local utility rates.
What is involved in installing a tankless unit in an existing Sunbright property?
1. Load & venting evaluation: We verify gas line diameter or electrical service capacity (most gas units need a ¾″ supply; electric models may require 120–200 amps). We also plan venting routes for combustion gases or air intake. 2. Permits & code compliance: Morgan County and the City of Sunbright require permits and inspection; we handle the paperwork. 3. Removal of old tank: We drain, disconnect, and haul away the storage tank. 4. Mounting & connections: The compact tankless unit is wall-mounted, then tied into water, gas or electrical, and venting lines. 5. Commissioning: We program temperature set-points, test for leaks, and demonstrate operation. Most conversions are completed in one day.
How much maintenance does a tankless water heater require?
Routine care is minimal but important. Sunbright’s water hardness averages 5–6 grains per gallon, so we recommend: • Annual descaling/flush with a vinegar solution to dissolve mineral buildup on the heat exchanger. • Cleaning the inlet filter every 6–12 months. • Checking venting and gas pressure annually. A service visit typically takes 60–90 minutes and keeps the unit under warranty, which is usually 12–15 years on the heat exchanger.
Are there rebates or incentives in Sunbright or Tennessee for upgrading to a tankless system?
Yes. As of 2024, Tennessee residents can claim a 30 % federal tax credit (up to $600) for qualifying ENERGY STAR® tankless units. Local utility companies such as Plateau Electric Cooperative periodically offer $100–$300 bill credits for high-efficiency gas or electric installations. We provide all paperwork and will alert you to current promotions when we prepare your estimate.
