FAQs
How much can I expect to save on my energy bills with a tankless water heater in Sevierville?
On average, homeowners in Sevierville see energy-bill reductions of 20–40 % after switching from a standard tank to an ENERGY STAR®-rated tankless unit. Traditional tanks keep 40–50 gallons of water hot 24/7, so you pay for standby heat loss. A tankless model only heats water when you open a tap, so you stop paying to maintain that large reservoir. Exact savings depend on your household’s hot-water usage, the efficiency of the unit selected (look for a UEF of 0.90 or higher), local electric or natural-gas rates, and whether we replace electric resistance or older gas equipment. We provide an energy-savings calculation during our in-home estimate so you’ll know what to expect before we install.
What size tankless water heater do I need for my Sevierville home?
Sizing is based on two factors: 1) the maximum number of fixtures you may run simultaneously (flow rate measured in gallons per minute, GPM) and 2) the temperature rise required to heat Sevierville’s incoming water (typically 55 °F groundwater to 120 °F setpoint = 65 °F rise). For a family that might shower while running a dishwasher, you’ll likely need 7–9 GPM. Smaller households that use fixtures consecutively may need only 5 GPM. During our free consultation we add up your fixture flow rates, apply the local temperature-rise chart, and recommend the right unit—usually 160k–199k BTU for gas or 15–18 kW for electric. Proper sizing ensures you get endless hot water without paying for excess capacity.
How long does a typical tankless water heater installation take, and will my water be shut off?
Most replacements are completed in one business day. We first turn off water and fuel lines, drain your old tank, and remove it—usually 1–2 hours. Installing the new tankless unit, gas line upsizing or wiring upgrades, venting, and condensate drainage takes another 3–5 hours. We keep water service off only while we tie into your plumbing (about 60–90 minutes). We schedule installations around your routine, and emergency same-day service is available if your old tank has failed.
Are permits required for installing a tankless water heater in Sevierville, and do you handle them?
Yes. The City of Sevierville and Sevier County require plumbing and, when gas lines are involved, mechanical permits. Electrical permits are needed for new 240-V circuits on electric units. As a licensed and insured contractor, Energy Bills Plumbing pulls all required permits, schedules rough-in and final inspections, and provides you with documentation once the job passes. Handling the paperwork ensures your installation complies with the latest International Plumbing Code (IPC), National Fuel Gas Code (NFPA 54), and manufacturer warranty terms.
Does the hard water in Sevierville affect tankless water heaters, and how can I protect my unit?
Sevierville’s municipal water averages 6–10 grains per gallon, which is considered moderately hard. Mineral buildup can reduce heat-exchanger efficiency and trigger error codes. To protect your investment we install a ¾-inch isolation valve kit and flush port with every unit. We also recommend a whole-house sediment filter or a scale-reduction system such as a TAC (template-assisted crystallization) cartridge. Annual descaling with food-grade vinegar or a manufacturer-approved solution keeps your heat exchanger clean, maintains efficiency, and preserves the warranty.
What maintenance is necessary after installation, and do you offer service plans?
Routine tasks include: 1) annual descaling and filter cleaning, 2) flushing the condensate neutralizer (gas models), 3) inspecting the venting for obstructions, and 4) checking error-code history. Most homeowners can perform filter cleaning themselves, but descaling requires a pump and safe disposal of flushing solution. Our Bronze, Silver, and Gold service plans include yearly maintenance, priority scheduling, and parts-and-labor discounts. Regular service not only extends equipment life but also keeps your unit operating at peak efficiency, ensuring you continue to see lower energy bills.
