FAQs
What makes a tank-style water heater “high-efficiency,” and how does it differ from a standard model?
A high-efficiency (HE) tank water heater uses better insulation, advanced heat exchangers, electronic ignition (instead of a standing pilot on gas units), and often a powered or sealed-combustion vent. These upgrades boost the unit’s EF/UEF (Energy or Uniform Energy Factor) to 0.64–0.90, compared with 0.58–0.62 for many conventional heaters. The result is faster recovery, less standby heat loss, and 15-35 % lower energy consumption while still giving you the large stored volume homeowners expect.
How much money can I expect to save on utilities in Chattanooga’s climate?
Natural-gas rates in Chattanooga average about $1.25 per therm and electricity about 12¢/kWh. A 50-gallon standard gas heater typically uses 180–200 therms per year; an HE model can cut that to 130–150 therms, saving roughly $40-60 annually. On electric units, savings run $60-80 per year. Over the 10-15-year life of the heater, most families recover the entire price premium and often come out several hundred dollars ahead—plus they gain faster hot-water recovery during colder Tennessee winters.
Are rebates or tax incentives available for high-efficiency tank water heaters in the Chattanooga area?
Yes. Tennessee Valley Authority (TVA) periodically offers $50–$150 rebates on ENERGY STAR® high-efficiency electric units purchased through participating contractors. For gas units, Chattanooga Gas provides rebates up to $300 for models with a UEF ≥0.64. In addition, the federal Energy Efficient Home Improvement Credit (25C) can cover up to 30 % of the installed cost (max $600) on qualifying heaters through 2032. We handle all paperwork and will credit any utility rebate directly on your invoice when possible.
What size high-efficiency tank do I need for my household?
Sizing still follows first-hour rating (FHR). In Chattanooga, a family of 2–3 usually does well with a 40- or 50-gallon HE unit (FHR 60-70 gal). A family of 4–5 often opts for a 50- or 55-gallon high-recovery model (FHR 80-90 gal). Because HE heaters recover faster, you sometimes can choose a smaller tank than you had before and still meet demand. We perform a free onsite assessment that factors in simultaneous shower use, bedroom count, whirlpool tubs, and future additions before recommending a capacity.
How long does installation take, and will my existing plumbing or venting need to be modified?
Most replacements are completed in 3–5 hours. If you’re upgrading from a standard gas unit to a condensing HE model, we may install PVC venting and a condensate drain; for electric models, the existing 240-V circuit is usually adequate. We’ll also bring the system up to current code—this can include an expansion tank, seismic strapping, or a vacuum-breaker in Hamilton County. All labor is performed by licensed, bonded plumbers, and we pull the required Chattanooga building permit on your behalf.
What maintenance is required and how long will a high-efficiency tank water heater last?
Plan on an annual flush to remove sediment common in Chattanooga’s moderately hard water and prolong efficiency. Gas units should have their burner assembly inspected and cleaned each year; electric units benefit from a quick element ohm-test. The anode rod should be checked every 3–4 years and replaced when 60 % depleted. With these steps, HE tank heaters routinely last 12–15 years—about the same as standard models—but they maintain higher efficiency throughout their service life.
