FAQs
How does a tankless water heater provide endless hot water?
Unlike traditional tanks that heat and store 40–80 gallons at a time, a tankless unit uses high-output gas burners or electric elements that activate the moment you open a hot-water tap. Cold water flows through a heat exchanger, is heated instantly, and travels directly to the fixture. Because the water is heated on demand and not stored, the supply continues for as long as the tap stays open, giving you virtually unlimited hot water.
Will a tankless unit meet my household’s hot-water demand in Apison?
Yes—when the unit is properly sized. We calculate the peak flow rate you need (for example, a shower plus a dishwasher running at the same time) and the temperature rise required (groundwater in Apison averages 58 °F, so to reach a 120 °F set point we need a 62 °F rise). A single whole-house unit often handles 5–7 gpm, enough for two showers and a sink simultaneously. Larger homes can use a high-capacity model or multiple smaller units in parallel to cover every fixture without pressure or temperature drops.
What are the energy savings and costs associated with switching to tankless?
The upfront investment is higher—typical installed costs in the Apison area range from $2,500 to $3,800 for gas and $1,800 to $3,200 for electric—but tankless heaters operate 24–34 % more efficiently than storage tanks because they eliminate standby heat loss. The U.S. Department of Energy estimates annual savings of $80–$120 on gas bills for an average-size family, with a life expectancy of 20+ years (compared with 10–12 years for a tank). That means lower replacement frequency and an overall lower cost of ownership over time.
How long does installation take and what does it involve?
Most residential jobs are completed in one day. We start by removing the existing tank, then mount the compact tankless unit on a wall (usually the same utility closet or garage). For gas models, we upgrade the gas line if necessary to supply the higher BTU demand and install category-III or IV stainless-steel venting. For electric units, we verify amperage and may add a dedicated breaker. After connecting water, gas/electric, and venting, we purge air, test for leaks, set the temperature, and demonstrate the controls. Your water is only off for about 1–2 hours during the swap.
Do tankless water heaters require maintenance?
Yes, but it’s simple. Because Apison’s water is moderately hard (around 7–9 grains per gallon), minerals can build up inside the heat exchanger. We recommend an annual 45-minute flush with food-grade vinegar or a citric-acid solution to dissolve scale, along with cleaning the inlet screen. Gas units also benefit from a quick inspection of the burner, vent, and condensate drain. Regular maintenance keeps efficiency high, prevents error codes, and preserves the manufacturer’s 10–15-year heat-exchanger warranty.
Are there rebates or incentives in the Apison area for installing a tankless water heater?
Yes. Tennessee Valley Authority (TVA) often offers $100–$300 rebates for ENERGY STAR® certified gas models. The federal Energy Efficient Home Improvement Credit (2023-2032) gives you up to 30 % of the cost, capped at $600, for qualifying equipment. Some natural-gas providers in Hamilton County provide additional bill credits. Our team stays current on all programs and will file the paperwork for you so you receive every available incentive.
