FAQs
What are the main benefits of installing a tankless water heater in my Cowan home?
Tankless (on-demand) water heaters heat water only when you open a tap, eliminating standby heat loss that occurs with storage tanks. In Cowan’s moderate Tennessee climate that translates into energy-use reductions of 25–40 %, lower monthly utility bills, and a continual supply of hot water—no more running out during back-to-back showers. Tankless units are wall-mounted, freeing up floor space, and their life expectancy (20+ years) is roughly double that of traditional tank heaters. Environmentally, they generate fewer greenhouse-gas emissions and most models qualify for federal or local efficiency rebates.
How long does a typical tankless water heater installation take?
For most single-family residences in Cowan, a straight replacement of a tank unit with a gas or electric tankless model takes 4–8 hours. This time frame covers removal of the old heater, rerouting or upsizing gas, water, and vent lines, mounting the new unit, pressure and leak testing, and final start-up calibration. If electrical upgrades, new vent penetrations, or relocation of the heater are required, the job can extend to a full day. We schedule a pre-site visit so you know the exact scope and time before work begins.
What size (flow rate) tankless water heater do I need?
Sizing is based on simultaneous hot-water demand and incoming ground-water temperature, which averages 55-60 °F in Cowan. We add up gallons-per-minute (GPM) needs for the fixtures likely to be used at once—for example, a shower (2.0 GPM) plus a dishwasher (1.5 GPM) equals 3.5 GPM. To raise 55 °F water to a 120 °F setpoint (65 °F rise), you’d want a unit rated around 7 GPM, giving headroom for peak events. Homes with three or more baths, soaking tubs, or multiple teenagers sometimes benefit from two smaller units in parallel for balanced demand and redundancy. During our consultation we perform a precise load calculation to recommend the right size.
Do I need permits or inspections for a tankless installation in Cowan?
Yes. Franklin County requires a mechanical permit for gas-fired units and an electrical permit if new circuits or panels are added for electric models. Gas line modifications are subject to pressure testing and inspection, and condensing units need approved vent terminations. We handle all permitting, schedule the city/ county inspections, and provide you with the signed-off documents for your records and future home resale. Skipping permits can void warranties and create insurance issues, so we make compliance effortless for you.
How much can I expect to save on my energy bills?
Savings depend on water-use habits and the fuel you switch from. Gas tankless units typically cut natural-gas consumption by 20–40 % compared to a standard 0.60-EF tank, equating to $80–$150 per year for an average Cowan household. Electric tankless heaters avoid standby losses entirely, so customers moving from an aging electric tank often see 25–50 % reductions—about $150–$250 annually at current TVA electricity rates. Adding a recirculation pump with a smart timer or activation button can boost convenience without significantly affecting those savings.
What maintenance does a tankless water heater require and do you service what you install?
Unlike tanks that accumulate rust and sediment, tankless units stay clean internally but their heat exchanger can scale up if Cowan’s moderately hard water (5–7 grains) is left untreated. We recommend a quick annual checkup: • Flush the heat exchanger with a vinegar solution for 45 minutes to dissolve mineral buildup. • Clean the inlet filter and inspect venting, gas pressure, and condensate drain. • Update firmware on models with smart controllers. We offer a low-cost annual service plan that covers all of the above, extends the manufacturer’s warranty, and provides priority same-day repairs if anything ever goes wrong.
