FAQs
What are the main advantages of switching to a tankless water heater in Cookeville?
Tankless units heat water on demand, so you’re not paying to keep 40–80 gallons hot all day. In Cookeville’s climate, that typically translates to 20–40 % lower energy bills compared with a standard tank. You also gain virtually endless hot water, a unit that lasts 20+ years (about twice the life of a tank model), and up to 80 % less floor-space usage—ideal if you want to reclaim a closet or basement corner.
How long does a professional tankless installation take, and will I be without hot water?
Most residential installs in the Cookeville area are completed in one business day. We start by safely de-energizing and draining your old tank, mount the new tankless heater, run venting and gas/electrical connections, and finish with start-up calibration. You’ll be without hot water for roughly 4–6 hours; we always schedule work to minimize disruption and test every fixture before we leave.
Do I need to upgrade my gas line, venting, or electrical service?
Sometimes. Gas-fired tankless heaters require ¾-inch gas lines and Category III or IV stainless venting, while electric models may need a 200-amp panel and multiple 40- to 50-amp breakers. During our free on-site assessment, we measure gas pressure, panel capacity, and vent routes. If upgrades are needed, we’ll give you a firm price and handle all work—including permits—so there are no surprises on installation day.
What size tankless water heater should I buy for my household?
Sizing is based on simultaneous demand (gallons per minute) and temperature rise. For example, in Cookeville the incoming water is about 55 °F. To supply 2 showers and a dishwasher at once (about 6 GPM) with 120 °F water, you need a unit that can raise water 65 °F at 6 GPM—roughly a 180,000 BTU gas model or a 27 kW electric model. Our technicians calculate your exact needs so you never run out of hot water or overpay for a unit that’s too large.
Are there rebates or tax incentives available for tankless water heaters in Tennessee?
Yes. Through 2024, ENERGY STAR–qualified gas tankless models meeting ≥0.95 UEF can earn a federal tax credit of 30 % of project cost, up to $600. Tennessee Valley Authority often offers $200–$300 bill credits for high-efficiency gas units, and many local natural gas utilities serving Cookeville offer $100–$250 rebates. We provide all paperwork and documentation so you can claim every available incentive.
What maintenance does a tankless water heater require after installation?
Unlike tanks, a tankless unit doesn’t store water, but mineral scale can still build up on the heat exchanger. Manufacturers recommend a yearly flush with food-grade vinegar or descaling solution, especially in Cookeville’s moderately hard water. The process takes about an hour and keeps efficiency high and your warranty valid. We offer low-cost maintenance plans that include annual flushing, full system inspection, and priority service.
