FAQs
Why should I choose a tankless water heater for my Cookeville home instead of a traditional tank?
Tankless units heat water on demand, so you never run out of hot water—a big plus for families or homes with large soaking tubs. Because they don’t keep 40–50 gallons of water hot all day, they typically cut water-heating energy use by 25–40%. In Cookeville’s moderate climate, the incoming groundwater temperature is well within the efficient operating range for most models, allowing faster payback on utility savings. Tankless heaters are also wall-mounted, freeing up floor space and reducing the risk of catastrophic tank leaks.
How long does a typical tankless installation take and will my hot water be off for very long?
Most residential replacements are completed in one day. We start by safely disconnecting and removing your old tank, then mount the new tankless unit, upgrade gas or electrical service if needed, and install venting. Your water will usually be off 1–2 hours and gas/electric service interrupted only while we make final connections. We schedule installations Monday–Saturday in Cookeville and surrounding Putnam County, and we always test the system and show you how to operate it before leaving.
What size (GPM) tankless water heater do I need?
Sizing is based on the total gallons per minute (GPM) of hot water your household may use at once and the temperature rise required. In Cookeville, incoming water averages 55–60 °F; most people want 120 °F hot water, so we need a 60-65 °F rise. If you might run two showers (2.0 GPM each) and a dishwasher (1.5 GPM) together, you’d want at least a 5.5 GPM unit at a 60 °F rise. During our free in-home estimate, we’ll count fixtures, measure flow rates, and recommend an appropriately sized gas or electric model so you get endless hot water without overspending on capacity.
Will a tankless water heater really lower my utility bills?
Yes. ENERGY STAR®-qualified gas tankless models are up to 34% more efficient than new storage tanks and up to 50% more efficient than older, poorly insulated tanks. Many Cookeville homeowners report saving $80–$150 per year on natural gas. Electric tankless units eliminate standby heat loss entirely and can shrink electric bills by 15–25%, depending on usage. Over a 20-year lifespan, those savings often exceed the higher purchase price, and local TVA energy-efficiency rebates can shorten payback time even more.
Do I need to upgrade my gas line, venting, or electrical service?
Possibly. High-output gas units often require a ¾-inch gas line and Category III or IV stainless-steel venting. During your estimate we’ll check gas pressure, line size, and venting routes to give you a firm quote that includes any needed upgrades. Electric tankless units draw 80–120 amps, so older 100-amp panels usually need to be upgraded to 200 amps. We are licensed Cookeville plumbers who coordinate any electrical work with a licensed electrician to meet state and city codes, ensuring safe, code-compliant installation.
What maintenance is required and how is hard water in Cookeville handled?
Tankless heaters should be flushed with a vinegar or citric-acid solution once a year to remove mineral scale, which is especially important because Cookeville’s water hardness averages 5–7 grains per gallon. We install isolation valves to make this quick and simple, and we offer affordable annual maintenance plans that include flushing, filter cleaning, and a full system check. Most manufacturers provide 5-year parts and 12-year heat exchanger warranties; by following the recommended maintenance schedule, you keep that warranty intact and maximize unit life—typically 20+ years.
