FAQs
What are the main advantages of switching to a tankless water heater in Lookout Mountain?
Tankless units heat water on demand, so you never run out of hot water—even during back-to-back showers after a hike on Lookout Mountain. They’re up to 40 % more energy-efficient than storage tanks, freeing up closet or garage space, and their 20-year average life span is nearly double that of a conventional heater. Because they use less energy, they reduce your carbon footprint and qualify for utility rebates and federal tax credits. The robust freeze-protection built into modern units is ideal for the colder winter nights we experience at higher elevations.
How long does a typical tankless water heater installation take?
Most residential installations are completed in a single day. We arrive in the morning, remove the old tank, mount the new unit, run upgraded gas or electrical lines if needed, install stainless-steel venting, and complete start-up and safety checks. If local permit inspections are required, the total project may extend to two calendar days, but your hot-water downtime is generally limited to 4–8 hours.
Is my existing gas or electrical service sufficient for a tankless unit?
Gas models need a ¾-inch gas line and up to 199,000 BTU/hr, while electric models require 240 V service and breakers up to 150 A depending on size. During our free on-site evaluation we measure line size, meter capacity, and panel load. If upgrades are necessary, we provide clear, upfront pricing and coordinate all electrical or gas work so the installation meets Tennessee code and manufacturer warranty requirements.
What size tankless water heater does my household need?
Sizing is based on simultaneous demand (gallons per minute) and required temperature rise. In Lookout Mountain, incoming water averages 50–55 °F, so to reach a 120 °F setpoint you need a 65–70 °F rise. A family with two bathrooms, a dishwasher, and a washing machine running together typically needs 7–9 GPM. During our consultation we calculate your peak flow rate, review fixture counts, and recommend the right model so you always have enough hot water without overspending on capacity you’ll never use.
How much can I expect to save on energy bills with a tankless water heater?
Homeowners usually see energy-bill reductions of 20–35 %, or about $80–$150 per year, because tankless units avoid standby heat loss. Savings are higher for larger families and for homes that previously kept a 50- or 75-gallon tank cycling all day. With local EPB and Tennessee Valley Authority rebates, plus the federal 30 % Energy-Efficient Home Improvement credit (up to $600), many customers recoup the price difference in five to seven years.
What maintenance is required to keep my tankless water heater running efficiently?
Annual maintenance is simple: 1) isolate the unit, 2) flush the heat exchanger with white vinegar or manufacturer-approved descaler for 30–45 minutes to remove mineral buildup from Lookout Mountain’s moderately hard water, 3) clean the inlet filter, and 4) inspect venting and condensate lines. The process costs far less than replacing a rusty tank and takes about an hour. Endless Comfort Plumbing offers affordable maintenance plans that preserve your warranty and ensure peak performance year after year.
