FAQs
Why should I choose a tankless water heater for my Duff home instead of a traditional storage‐tank model?
Tankless units heat water on demand, so you never run out of hot water and you avoid the standby heat losses that come with a 40- or 50-gallon tank. In Duff’s moderate-to-cool climate, that translates to energy savings of 20-40 % a year, lower utility bills, and a smaller carbon footprint. You also free up floor space, gain a unit that typically lasts 20+ years (about twice the life of a tank), and become eligible for federal tax credits and local utility rebates when you install an Energy Star–certified model.
What size and fuel type of tankless water heater do I need?
Proper sizing depends on (1) the number of fixtures you want to run at once, (2) the flow rate of each fixture, and (3) incoming groundwater temperature—which averages 55-60 °F in Duff. We calculate your peak gallons-per-minute (GPM) demand and match it to a gas or electric model that can raise that water to 120 °F. A typical three-bathroom home in Duff needs a 9–11 GPM natural-gas unit or a 27 kW electric model. During your free in-home assessment, our technician measures actual flow rates and reviews gas, propane, or electrical service to recommend the most efficient, code-compliant option.
Will I need to upgrade my gas line or electrical service?
Possibly. High-efficiency gas tankless heaters draw 120,000–199,000 BTU/h and often need a ¾″ gas line instead of the ½″ line serving a tank heater. Electric models can require a 120- to 150-amp dedicated breaker set and 4- or 6-gauge wiring. During our site visit we perform a load calculation, check meter capacity, and examine your panel or propane regulator. If an upgrade is necessary, we provide a detailed quote and coordinate all gas, electrical, and venting modifications so the new unit performs safely and meets Tennessee Mechanical and Fuel Gas Codes.
How long does a professional tankless installation take and will I be without hot water?
A straightforward replacement in Duff usually takes 4–6 hours for gas units and 6–8 hours for electric units that need new wiring. You’ll be without water for roughly 1–2 hours while we reroute plumbing connections. We schedule installations at your convenience, arrive with all parts on the truck, test every connection, and haul away the old tank so you can enjoy endless hot water the same day.
What permits, inspections, and warranties apply to a tankless install in Duff?
Campbell County (Duff) requires a mechanical/plumbing permit for any water-heater change-out and a separate electrical permit if wiring is added or modified. Our office handles the paperwork, pays the fees, and schedules the county inspector. We provide a workmanship warranty of 2 years on labor, the manufacturer supplies 5-year parts and 15-year heat-exchanger coverage, and registering the unit within 30 days secures the full warranty period.
What ongoing maintenance does a tankless water heater need and how long will it last?
Because Duff’s water measures about 5–7 grains per gallon of hardness, we recommend a yearly descaling/flush to remove mineral buildup and keep efficiency high. The process takes about one hour and costs far less than replacing a scaled heat exchanger. You should also clean the inlet filter every 6 months and check the condensate drain (for condensing models). With regular maintenance, tankless water heaters average 20–25 years of service life—roughly double that of tank units—making them a smart long-term investment.
