FAQs
How does a tankless water heater provide “endless” hot water compared with a conventional storage tank?
Traditional tanks keep 40–80 gallons of water hot all day, so when the stored supply is depleted you have to wait for it to re-heat. A tankless unit has no reservoir; instead, a powerful heat exchanger senses flow and heats water only when a hot-water tap opens. Because incoming cold water is heated continuously as it passes through the unit, you can shower, do laundry, and run the dishwasher back-to-back without running out—as long as the combined flow stays within the unit’s rated capacity.
Is a tankless water heater a good choice for homes in Lynchburg’s climate and water conditions?
Yes. Lynchburg’s incoming water temperature averages 55–60 °F, well within the design range of modern gas and electric tankless models. Our area’s moderately hard water (about 4–6 grains per gallon) means scale can build up but is easily managed with annual descaling or a simple in-line filter. Local natural-gas availability and relatively low electric rates also make tankless systems cost-effective for most households.
What size or capacity tankless unit do I need for my family?
Sizing is based on total flow rate you expect to use at one time—not the number of bathrooms. We calculate: (1) how many fixtures may run together, (2) their gallons-per-minute (GPM) draw, and (3) the required temperature rise from incoming water to your preferred 120 °F set-point. For example, one shower (2.0 GPM), a dishwasher (1.5 GPM), and a sink (1.0 GPM) running simultaneously would need roughly 4.5 GPM at a 60 °F rise—so a 5-GPM unit would suffice. During a free in-home estimate we’ll measure actual fixtures and recommend the correct model so you never feel a drop in pressure or temperature.
How much can I expect to save on energy bills after switching to tankless?
The U.S. Department of Energy reports that gas-fired tankless heaters are 24–34 % more efficient than storage tanks for households using 41 gallons or less of hot water daily, and 8–14 % more efficient for heavy-use households. In Lynchburg, that usually translates to $80–$150 per year in fuel savings. Because the units last 20+ years—about twice the life of a tank—total lifecycle savings can exceed $1,500, not counting space savings and reduced leak risk. Appalachian Power and Columbia Gas periodically offer rebates of $150–$300, which we’ll help you apply for.
What does the installation process involve and are permits required in Lynchburg?
1) Site visit: We confirm venting options, gas line size, electrical availability, and mounting location. 2) Permits: The City of Lynchburg requires plumbing and, for gas units, mechanical permits. Our licensed master plumbers obtain and close these for you. 3) Upgrade work: Many homes need a larger ¾″ gas line or a 120-V outlet; electric models may need a 100-amp breaker. We handle all modifications. 4) Mounting & connections: The compact unit is wall-hung, then water, gas/electric, and condensate lines are attached. Stainless-steel venting is routed through an exterior wall or roof. 5) Commissioning: We program temperature, check combustion, flush the heat exchanger, and demonstrate operation. Most residential jobs take one day, and your old tank is removed and recycled.
What routine maintenance does a tankless water heater require, and can you service it?
Unlike old tanks, tankless units don’t corrode from stored water, but the heat exchanger can collect mineral scale. We recommend: • Annual descaling/flush using food-grade vinegar or a citric solution (takes about 45 minutes). • Cleaning or replacing the inlet screen filter every 6–12 months. • Checking venting, gas pressure, and condensate drain during the flush visit. Our Endless Hot Water Plumbing team offers affordable maintenance plans that include reminders, service discounts, and priority scheduling, so your unit stays under manufacturer warranty and operates at peak efficiency for decades.
