FAQs
What are the main advantages of a tankless water heater compared with a traditional tank unit?
A tankless (on-demand) water heater heats water only when you open a tap, eliminating standby heat loss and saving 20-40 % on water-heating energy use. Because there is no storage tank, you also gain virtually endless hot water, a unit that is roughly the size of a suitcase (freeing up floor space), and equipment that typically lasts 18-20 years—about twice as long as a standard tank. Many Gatlinburg homeowners also like that tankless models reduce the risk of catastrophic leaks associated with aging storage tanks.
Do I really need a licensed plumber to install a tankless water heater in Gatlinburg?
Yes. Tennessee plumbing and mechanical codes require that any gas, propane, or electric water-heating appliance be installed by a state-licensed and properly insured contractor. A licensed technician ensures safe gas-line sizing, correct venting through combustible cabin walls, compliance with electrical load calculations, and permitting with the City of Gatlinburg or Sevier County. Using an unlicensed installer can void the manufacturer’s warranty and may lead to safety hazards or fines if your home is inspected or sold.
How long does a typical tankless water heater installation take and what does it involve?
For most single-family homes in the Gatlinburg area, a straightforward replacement takes 4–6 hours. The crew will 1) shut off water, power, and fuel supply; 2) remove the old tank; 3) upgrade gas or electrical service if needed; 4) mount the tankless unit to an exterior or interior wall; 5) install category-III or polypropylene venting through the roof or sidewall; 6) connect water, recirculation, and condensate lines; 7) perform leak, combustion, and electrical tests; and 8) obtain final inspection. More complex jobs—such as relocating the heater or adding a dedicated 240-V circuit—can extend the project to a full day.
Are there special permits or code requirements for tankless water heaters in Gatlinburg or Sevier County?
Yes. The International Residential Code (IRC) as adopted by Gatlinburg requires a mechanical permit for gas or propane units and an electrical permit for units over 12 kW. Venting must terminate at least 3 ft from windows and 10 ft from mechanical air intakes. Gas piping must be sized for the appliance’s BTU input plus existing loads, and condensate from high-efficiency units must drain to an approved location. Our licensed technicians handle all permit applications and coordinate final inspection so you don’t have to navigate the paperwork.
How do I know what size (GPM and BTU) tankless water heater my home needs?
Sizing is based on peak hot-water demand and incoming water temperature. Our technicians calculate the total gallons per minute (GPM) your fixtures may use simultaneously—typically 6–8 GPM for a three-bath Gatlinburg cabin—then factor in winter inlet temperatures (about 50 °F). A 199,000-BTU gas unit delivering 9-10 GPM at a 70-degree rise is common for larger homes, while a 150,000-BTU model might suffice for smaller residences. Electric tankless units require substantial amperage and are usually recommended only for point-of-use or small apartments. We provide a free on-site evaluation to make sure the unit we install matches your household’s needs and your utility capacity.
What does a tankless water heater installation cost in Gatlinburg and are rebates available?
Installed prices range from $2,700–$4,500 for standard-efficiency natural-gas models and $3,500–$5,800 for high-efficiency or propane units, depending on capacity, venting complexity, and required utility upgrades. Electric units cost $900–$1,800 installed but may need expensive panel upgrades. Local utility Sevier County Electric System offers a $200 rebate for ENERGY STAR gas models, and TVA’s EnergyRight program provides low-interest financing for qualifying energy-efficient upgrades. Federal tax credits of 30 % up to $600 are also available through 2032 when you install an ENERGY STAR certified tankless heater with at least 0.95 UEF. Our office completes the rebate paperwork and furnishes the IRS form so you get every dollar you’re eligible for.
