FAQs
How does a tankless water heater improve energy efficiency compared with a conventional storage tank model?
Traditional water heaters continually heat 40–80 gallons of water so it is ready when you need it—even while you are asleep or at work—causing “stand-by” losses. A tankless unit, by contrast, uses high-output burners or heating elements to warm the water only when a hot-water tap opens. Because there is no storage tank, stand-by losses are virtually eliminated and overall efficiency rises to 82 – 98 percent, depending on the model. For many Cookeville households this translates into 25 – 40 percent lower water-heating energy use and annual utility-bill savings of $75–$150.
Is a tankless water heater a good fit for Cookeville’s climate and water quality?
Yes. Central Tennessee’s moderate groundwater temperatures (typically 55 – 60 °F) keep required temperature rise within the sweet spot of most tankless models, so flow rates remain strong. Cookeville’s municipal water is considered moderately hard at roughly 80 mg/L, which means scale can form over time but is easily managed with an annual flush or an inline scale-reduction filter. Natural-gas service is available in most neighborhoods, but we also install propane and high-efficiency electric units for homes outside the gas grid.
What size (flow rate) tankless unit will my Cookeville home need?
Sizing is based on two factors: 1) the temperature rise between incoming water and your desired hot-water temperature, and 2) the total gallons per minute (GPM) you may draw at one time. A typical family of four in Cookeville, running one shower (2.0 GPM) and a dishwasher (1.5 GPM) simultaneously, needs at least 3.5–4.0 GPM at a 60 °F rise. We perform a free in-home assessment to calculate peak demand, verify gas-line capacity or electrical service, and recommend a properly sized unit—usually 7–11 GPM for whole-house gas models or 14 kW-plus for electric.
What does the installation process involve and how long will it take?
After the sizing visit, we pull the required city or Putnam County permit and schedule a one-day installation. The crew removes your old tank, mounts the compact tankless unit on a wall, upgrades gas piping or electrical wiring if needed, installs stainless-steel or PVC venting, and adds isolation valves for future maintenance. Most jobs take 6–8 hours; complex retrofits or relocations can run into a second day. Before we leave, we test for gas leaks, verify vent draft, set the temperature, and show you how to use the digital controller.
How much does a tankless system cost and are there any rebates for Cookeville residents?
Turn-key installations in our area generally range from $2,800 to $4,500 for a gas unit and $2,200 to $3,500 for an electric model, depending on capacity and site conditions. Homeowners may qualify for a 30 percent federal tax credit (up to $600) on select ENERGY STAR-certified units, plus TVA’s EnergyRight Home Uplift rebates or low-interest financing through local utilities such as CUC. We handle all paperwork and provide itemized invoices so you capture every available incentive.
What maintenance and life expectancy should I expect from a tankless water heater?
With proper care, today’s tankless heaters last 20 + years—roughly twice the life of a storage tank. Annual maintenance is simple: close the isolation valves, circulate food-grade vinegar or a descaling solution for 45 minutes to dissolve mineral buildup, clean the inlet screen, and check the vent for obstructions. Our service team offers a low-cost annual tune-up that keeps your warranty intact and ensures peak efficiency. Because there is no tank, you also avoid catastrophic leaks and 50-gallon floods common with aging conventional heaters.
