FAQs
How do tankless water heaters reduce energy costs compared to traditional tanks?
Traditional storage-tank heaters constantly keep 40-80 gallons of water hot, which means they cycle on and off all day— even when you are at work or asleep. A tankless (on-demand) water heater heats water only when a hot-water tap is opened. Because standby losses are eliminated, most models use 24-34 % less energy than a conventional electric tank and 12-18 % less than a gas tank. In a typical Tullahoma home that spends $400-$600 a year on water heating, that can translate to $75-$150 in annual savings.
Are tankless water heaters suitable for Tullahoma’s water quality and climate?
Yes. Tullahoma’s municipal water is moderately hard (6-7 grains per gallon), well within the range recommended by every major tankless manufacturer. A simple in-line sediment filter and annual descaling keep mineral buildup under control. Our mild winters also mean incoming water temperatures rarely fall below 50 °F, so even mid-sized units can raise water to a comfortable 120 °F without struggling or cycling excessively.
What size tankless unit do I need for my Tullahoma home?
Sizing is based on two factors: 1) flow rate (gallons per minute) of all fixtures you might use simultaneously, and 2) the temperature rise required. In Tullahoma we usually need a 70 °F rise (from 50 °F to 120 °F). A family of four that may run two showers and a dishwasher at once typically needs 7–8 GPM at that rise, so we recommend a 180,000 BTU natural gas or a 27 kW electric unit. Smaller households or those with staggered usage can often use a 4-6 GPM model. Our technician will calculate your exact demand during the onsite assessment.
How long does installation take and will my hot water be disrupted?
Most retrofit installations take 4-6 hours. We start by shutting off water and power/gas, disconnecting the old tank, mounting the new compact unit, upgrading gas line or electrical circuit as needed, then running venting and condensate drains. You’ll be without hot water for only 2-3 hours. We schedule work at your convenience and always test the system before we leave so you have reliable hot water that same day.
What maintenance is required to keep a tankless water heater efficient?
Maintenance is simple: 1) Flush the heat exchanger with a vinegar solution once a year to remove scale; 2) Clean or replace the inlet filter every 6 months; 3) Inspect venting and condensate drain yearly. These tasks take about 45 minutes and can be done by our technicians or DIY if you’re handy. Proper maintenance can extend service life to 20+ years— nearly double that of a storage tank.
Are there rebates or incentives for installing a tankless water heater in Tullahoma?
Absolutely. As of 2024, TVA’s EnergyRight program offers up to $250 for qualifying ENERGY STAR® natural gas or electric tankless models. Federal tax credits under the Inflation Reduction Act cover 30 % of the installed cost (up to $600). Local utility, Tullahoma Utilities Authority, occasionally runs seasonal incentives of $100-$150. We handle all paperwork and provide the necessary documentation so you receive every available rebate and credit.
