FAQs
What are the main advantages of installing a wall-mounted tankless water heater in my Sequatchie home?
Tankless units heat water on demand, so you never run out of hot water and you eliminate standby heat loss from a storage tank—often cutting water-heating energy use by 25–40 %. Wall mounting frees up floor space and keeps the unit safely above potential flood zones. Because Sequatchie’s building lots can be tight, the compact footprint is a big plus. Most models also qualify for federal tax credits and local TVA incentives, helping offset the initial cost.
How do I determine the correct size (flow rate) tankless water heater for my household?
Sizing is based on peak hot-water demand, expressed in gallons per minute (GPM), and on the incoming water temperature in Sequatchie (typically 55–60 °F in winter). We add up the flow rates of fixtures you might run simultaneously—e.g., shower (2.5 GPM) + dishwasher (1.5 GPM) = 4 GPM—then pick a unit that can raise that water to 120 °F at that flow. For most three-bedroom Sequatchie homes, an 8–10 GPM gas unit or a 6–8 GPM electric unit is adequate; larger families or luxury bathrooms may need 11 GPM or more. Our technicians perform a free on-site assessment to confirm the exact size before installation.
Will a tankless system work with my existing gas, propane, or electrical service and plumbing?
In many cases, yes—especially for natural gas or propane homes—but some upgrades may be required. Gas tankless heaters need a ¾-inch gas line and 4- to 6-inch category III or IV stainless steel venting, plus a condensate drain. Electric models often need a 200-amp service with two or three dedicated 40- to 60-amp breakers and 8- or 6-gauge wiring. Plumbing tie-ins are straightforward; we install isolation valves and a back-flush port without disturbing drywall. During your estimate, we inspect utility lines, panel capacity, vent routes, and wall structure so there are no surprises on install day.
What happens on installation day and how long does the process take?
A standard swap-out from a tank to a wall-mounted tankless unit takes 4–6 hours. We begin by shutting off water and power/gas, draining and removing the old heater, then mounting the tankless unit on a fire-rated backer board. Next we run venting through the nearest exterior wall or roof, connect gas or electrical, and reroute hot- and cold-water lines with isolation and pressure-relief valves. We finish with a combustion analysis or electrical load test, set the temperature, and show you how to operate the unit. Permits and a Sequatchie County inspector sign-off are included in our turnkey service.
How much can I expect to save on utility bills, and does the climate in Sequatchie affect efficiency?
Most customers report annual utility savings of $75–$150 versus a 40- or 50-gallon tank, depending on hot-water usage and fuel type. Gas units are 93–98 % efficient; electric models are 99 %. Because Sequatchie winters are milder than northern states, incoming water isn’t as cold, so the heater works less to reach set temperature, boosting efficiency year-round. For electric customers on TVA’s Time-of-Use program, using hot water outside of peak hours can add another 5-10 % in savings.
What routine maintenance is required, and do you offer service plans for Sequatchie residents?
Tankless heaters should be descaled (flushed with vinegar or food-grade citric solution) once a year to remove mineral buildup from the copper heat exchanger—more often if your home has hard water from Sequatchie’s well sources. We also recommend cleaning the inlet screen filter every six months and performing a combustion check or electrical diagnostic annually. Our ComfortCare plan covers all required maintenance visits, priority scheduling, discount parts, and extends the manufacturer’s warranty to 15 years on the heat exchanger and 5 years on parts for most brands.
