FAQs
Why should I consider a tankless water heater for my Signal Mountain home instead of a conventional storage tank?
Tankless units heat water on-demand, so you eliminate standby heat loss from a 40–50 gal tank. In Signal Mountain, where winter nights can dip below freezing, a tankless heater with built-in freeze protection ensures you still have hot water without wasting energy keeping a full tank warm. Homeowners typically see energy savings of 20–40 %, enjoy unlimited hot water for long showers after hiking the Cumberland Plateau, and free up valuable basement or crawl-space square footage.
Does the cooler incoming water temperature on the mountain change the size or model I need?
Yes. Ground-water temperatures on Signal Mountain run 5–10 °F cooler than in the valley, which means the heater must raise the water temperature more degrees per minute. We perform a detailed load calculation that factors in: (1) the lowest recorded supply water temp here (about 50 °F), (2) the desired outlet temp (120 °F for most homes), and (3) the number of simultaneous fixtures you want to run. This sizing process often points to a 180,000 BTU gas unit or a 27 kW electric unit for a three-bath home, whereas the same home in Chattanooga proper might need one step smaller.
Which fuel type—natural gas, propane, or electric—works best on Signal Mountain?
• Natural gas is the most cost-effective if you already have municipal service through Chattanooga Gas. • Propane is common for homes past the gas main; we can install an external tankless model and tie into your existing propane storage. • Whole-home electric tankless systems are possible, but the home must have at least 200 amp service and space in the panel for multiple 40–50 amp breakers. In areas where power outages are a concern, many customers pair electric units with a backup generator. We’ll compare fuel costs, available utilities, and your electrical capacity during the site visit so you select the most economical option long-term.
What is involved in a professional tankless installation on the mountain?
1. Permit & Code Compliance – Hamilton County requires a mechanical/plumbing permit and inspection; our licensed plumbers pull all paperwork for you. 2. Gas Line or Electrical Upgrade – Tankless gas units need a ¾" gas line and sometimes a 2-psi meter; electric models may require a service-panel upgrade. 3. Venting & Combustion Air – We route Category III/IV stainless or PVC vent pipe to meet the longer horizontal runs often needed in split-level mountain homes. 4. Water Quality Treatment – Signal Mountain’s well and municipal supplies can be slightly hard; we install a scale-inhibitor filter to protect the heat exchanger. 5. Start-Up & Calibration – We verify flow rate, temperature rise, and activate freeze-protection mode for winter.
How much will I save on my utility bills and what is the typical payback period?
Gas tankless owners on Signal Mountain report $80–$150 in annual savings compared with a 50-gallon atmospheric tank, thanks to 0.93+ Uniform Energy Factor ratings and no standby loss. Electric unit savings depend on TVA’s residential kWh rate but average 15–25 %. Upfront costs run $3,200–$4,800 installed (gas) and $2,800–$3,600 (electric) after available EPB/TVA rebates. Most families recoup the investment in 5–7 years; larger households with high hot-water demand see payback in as little as 3–4 years.
What maintenance do tankless water heaters require, and do you offer service plans?
Annual maintenance keeps your warranty valid and efficiency high. We perform a complete checklist: (1) flush the heat exchanger with food-grade vinegar to remove mineral scale, (2) clean the inlet filter screen, (3) test ignition and freeze-protection circuits, and (4) update error-code history. For homes with very hard water, we may recommend a bi-annual flush. Our Gold Service Plan includes this maintenance visit, priority same-day hot-water service, and a 10 % discount on any future repairs.
