FAQs
What are the main advantages of switching to a tankless water heater in Maynardville?
Tankless units heat water on demand, eliminating the standby heat loss that occurs with storage tanks. Homeowners typically see energy-use reductions of 25–40 %, endless hot water for back-to-back showers, a space-saving wall-mount design, and life expectancies of 20+ years—roughly double that of conventional tanks. Because our Maynardville technicians size and install the system correctly, you also gain better reliability and a manufacturer-backed warranty of up to 15 years on the heat exchanger.
How long does a professional tankless installation usually take?
For most residential replacements, our experienced team completes the job in one working day (6–8 hours). This time frame includes removing the old tank, modifying gas lines or electrical circuits, installing intake and exhaust venting through an exterior wall or roof, mounting the new unit, and performing a full start-up/commissioning. Complex retrofits—such as relocating the water heater, upgrading a gas meter, or adding a recirculation loop—can extend the project to two days, but we’ll provide an exact timeline during your in-home estimate.
What size (GPM rating) tankless water heater do I need for my household?
Sizing is based on two factors: the peak gallons-per-minute (GPM) demand of simultaneous fixtures and the required temperature rise (the difference between incoming water temperature and your target hot-water temperature). In Maynardville, ground-water temperatures average 55-60 °F. A family of four that runs two showers and a dishwasher at once typically needs a 9–10 GPM gas unit or an 18–27 kW electric model. Our technicians calculate these numbers on site, consider future additions, and recommend a correctly sized heater so you never run out of hot water.
Will a tankless water heater really lower my utility bills?
Yes. ENERGY STAR® data show that gas tankless units save the average household about $95 per year compared with a standard 40-gallon gas tank, while electric tankless models can cut electric water-heating costs by 20–30 %. Savings stem from eliminating standby losses and using high-efficiency (up to 0.97 UEF) heat exchangers that modulate only to the BTU level required. Your exact savings depend on hot-water usage patterns, fuel prices, and the efficiency of the old heater being replaced.
Do you offer maintenance and repair services after installation, and what is required to keep the warranty valid?
Absolutely. We provide annual or bi-annual service plans that include descaling the heat exchanger, cleaning the combustion chamber, checking gas-pressure settings, flushing the inlet filter, and updating firmware (for Wi-Fi-enabled models). Most manufacturers require documented descaling at least once a year in moderate-to-hard water areas—Maynardville falls into this category—to maintain warranty coverage. If you ever experience an error code or performance issue, our on-call technicians carry factory parts for same-day repairs.
Are permits or special code requirements needed for a tankless installation in Maynardville?
Yes. Union County and the City of Maynardville follow the 2018 International Residential Code (IRC) and International Fuel Gas Code (IFGC). A mechanical permit is required for venting alterations, and a plumbing permit covers water and gas line modifications. Gas units must vent horizontally or vertically with category-III/IV stainless or PVC pipe, include a condensate drain, and have a gas supply sized to the manufacturer’s BTU rating. Our licensed plumbers handle all permitting, inspections, and code compliance, ensuring your installation is safe and approved.
