FAQs
What is a tankless water heater and how does it give me “endless” hot showers?
Unlike a storage-tank heater that repeatedly heats 40–50 gallons of water, a tankless (or on-demand) unit activates only when a hot-water tap opens. Cold water passes through a heat exchanger—gas-fired or electric—and is heated instantly, so there is no finite supply to run out. As long as the unit’s flow-rate capacity is not exceeded and utility service is available, you can shower for as long as you like without waiting for a tank to re-heat.
Will a tankless system work with my existing plumbing and water demands in Jellico?
In most homes the answer is yes, but we verify three things during an on-site visit: 1) the total gallons-per-minute (GPM) your fixtures can draw; 2) available natural-gas line size (or electric service capacity); and 3) venting or condensate drain routes. Smaller households (1–2 baths) often need only one whole-home unit, while larger homes may need a higher-BTU model or parallel units. Because Jellico’s incoming water temperature can drop to the low 40s °F in winter, we size equipment to ensure adequate hot-water output even on the coldest days.
How much can I expect to save on energy bills by switching to tankless?
The U.S. Department of Energy reports gas-fired tankless heaters can be 24–34 % more efficient for homes that use up to 41 gallons of hot water per day, and 8–14 % more efficient for heavier use. In Jellico, typical families see $80–$150 in annual utility savings compared with a standard 50-gallon tank, depending on local gas or electric rates and usage habits. Eliminating standby heat loss (keeping a full tank hot 24/7) is the main source of savings.
What size or capacity tankless water heater do I need?
Sizing is based on simultaneous demand, not the number of gallons stored. We total the flow rates of fixtures you are likely to use at the same time—e.g., a shower (2 GPM) + dishwasher (1.5 GPM) + laundry (2 GPM) = 5.5 GPM. Then we account for winter groundwater temperature to determine the required temperature rise. Most Jellico homes need 160,000–199,000 BTU gas units (or a 24–36 kW electric model) to deliver 6–8 GPM at a 70 °F rise. Our technician will perform the exact calculation and recommend a model that matches your lifestyle and budget.
What does the installation involve and do I need permits in Jellico?
A typical retrofit takes one day. We disconnect and remove your old tank, mount the new compact unit on a wall, upgrade the gas line or electrical circuit if needed, run stainless-steel venting (or PVC for condensing models), and connect water lines with isolation valves for easy service. The City of Jellico and Campbell County require plumbing and, for gas units, mechanical permits. As a licensed plumbing contractor, we secure the permits, schedule inspections, and ensure the installation meets local code, including back-flow prevention and proper combustion air supply.
What maintenance is required and how long will a tankless heater last?
Expect 20+ years of service—about double a conventional tank—when properly maintained. We recommend: 1) annual flushing with a vinegar solution to dissolve mineral scale (twice a year if you have hard water), 2) cleaning the inlet screen filter, and 3) inspecting the vent and condensate line. Our Jellico customers can join an affordable maintenance plan that covers these tasks and extends the heat-exchanger warranty up to 15 years on most brands.
