FAQs
What are the main advantages of switching to a tankless water heater in Chattanooga?
Tankless (on-demand) units heat water only when you open a tap, eliminating standby heat loss from a storage tank. That typically cuts energy use 20–40 %, which translates to lower EPB, EBP, or TVA electric/gas bills in Chattanooga. You also gain endless hot water—great for large families—plus a space-saving wall-mounted design and a life expectancy of 18–25 years (5–10 years longer than most tank models). Many homeowners also qualify for federal tax credits and local utility rebates that further reduce the net cost.
How do I determine what size tankless water heater my home needs?
Sizing is based on two factors: (1) the total flow rate of fixtures you might run at the same time (showers, dishwasher, washing machine, etc.), and (2) the “temperature rise” required—how much we must heat incoming water to reach 120 °F. In Chattanooga, groundwater averages 55–60 °F, so we plan for roughly a 60–65 °F rise. A typical three-bathroom home needs 6–8 gallons per minute (GPM). Our technician will calculate fixture flow rates, discuss lifestyle habits, and recommend the exact BTU and GPM rating so you never run out of hot water.
What is the typical cost of a tankless installation in the Chattanooga area, and when will it pay for itself?
Installed pricing usually falls between $3,200 and $4,800, depending on gas vs. electric, venting requirements, recirculation pumps, water-quality treatment, and any code upgrades (like new shut-off valves or expansion tanks). Because tankless units are 20–40 % more efficient and last almost twice as long, most homeowners see $125–$250 in annual energy savings. Combined with current 30 % federal tax credits (up to $600) and occasional EPB or Chattanooga Gas rebates, the simple payback period is typically 5–7 years—often sooner for larger families with higher hot-water demand.
How long does installation take and will I be without hot water?
A straightforward replacement of a gas tank water heater with a gas tankless unit usually takes 6–8 hours. Converting from electric to gas or relocating the heater can extend the job to a full day due to gas line upgrades or new venting. Your hot water will be off for only 2–4 hours while we disconnect the old unit and tie in the new one. We schedule convenient start times, bring all materials, pull the required Hamilton County permit, and handle final code inspection so you experience minimal disruption.
Will a tankless water heater handle Chattanooga’s colder winter inlet-water temperatures?
Yes. Modern high-BTU condensing units adjust flame intensity to deliver the set-point temperature even when winter groundwater dips into the low 50s. For very large homes or simultaneous multi-shower use, we may recommend either a higher-capacity model, parallel units, or a small buffer tank to ensure peak-demand flow. We also offer built-in or add-on recirculation loops so hot water reaches distant fixtures quickly, conserving water and adding comfort during chilly mornings.
What maintenance is required after installation, and do you offer service plans?
Tankless heaters need an annual 45-minute service: descaling the heat exchanger with food-grade vinegar (or citric solution), cleaning the inlet screen, and checking the burner, vent, and condensate drain. Chattanooga’s moderate hardness (4–6 grains) means scale can build up, especially on gas units, so staying on schedule preserves efficiency and warranty coverage. We offer affordable maintenance plans that include the annual flush, priority scheduling, and discounted repair rates. Most manufacturers require proof of professional service to honor their 10- to 15-year heat-exchanger warranties.
