FAQs
What are the main benefits of installing a high-efficiency tankless water heater in Ducktown?
Tankless units heat water on demand, so they eliminate standby heat loss and can reduce energy costs by 20–40 % compared with storage-tank models. Because they are compact, they free up floor space and can be wall-mounted almost anywhere. With proper sizing, they provide a continuous supply of hot water, so you never “run out,” even during back-to-back showers. Many models also qualify for state and federal efficiency rebates, lowering the net installation cost.
How do I know what size (flow rate) tankless water heater I need?
Sizing is based on the total gallons per minute (GPM) of hot water you expect to use at peak times and the required temperature rise from Ducktown’s incoming water temperature (typically 50–55 °F). We calculate the GPM of each fixture—e.g., 2.5 GPM for a shower, 1.5 GPM for a sink—add them up for simultaneous use, then match that to a unit that can supply the needed flow at a 70 °F rise. During your consultation we measure fixture flow, discuss usage habits, and run sizing software to recommend the correct model.
Will a tankless water heater work with my existing plumbing and gas/electric service?
In most Ducktown homes the water lines tie in easily, but gas and electrical upgrades may be required. Gas units often need a ¾-inch gas line and up to 200 k Btu/hr capacity, while electric models require a 240-V supply with 120-200 A service depending on size. We’ll inspect your current utilities, identify any necessary upsizing or breaker additions, and include those changes in a transparent quote before work begins.
How long does installation take, and will I be without hot water?
A typical retrofit installation takes 6–8 hours. We keep your old heater online until we’re ready to switch over, so hot water downtime is usually under one hour. If venting, gas line, or electrical upgrades are extensive, the job may extend to a second day, but we’ll outline the schedule in advance so you can plan accordingly.
What maintenance does a tankless water heater require in Ducktown’s water conditions?
Because Ducktown has moderate hardness (about 5–7 grains per gallon), annual descaling is recommended to keep the heat exchanger efficient. Maintenance involves flushing the unit with a vinegar or citric-acid solution for 45 minutes, cleaning the inlet screen, and checking venting and burner components. We offer a low-cost yearly service plan that includes the flush, safety inspection, and software update to maintain warranty coverage.
Are permits and inspections required for a tankless water heater installation in Ducktown?
Yes. The City of Ducktown Building Department requires a mechanical permit for any water heater replacement, plus a plumbing and/or gas permit if new lines are installed. Our licensed technicians handle the paperwork, schedule the city inspection, and ensure the installation meets the latest ICC and local code requirements. Final sign-off protects your homeowner’s insurance and assures the manufacturer that the unit was installed to spec.
