FAQs
What are the main benefits of installing a tankless water heater in Greenback?
Tankless units heat water on-demand, so you aren’t paying to store 40–80 gallons of hot water all day. Homeowners in Greenback typically see energy-use reductions of 25-40 percent, longer equipment life (20+ years versus 10-15 for tanks), endless hot water for showers or tubs, and reclaimed floor space because wall-hung models are compact. In addition, most units qualify for federal tax credits and TVA energy-efficiency rebates available in the Greenback area.
How long does a typical tankless water heater installation take?
For most single-family homes, our licensed plumbers can complete a full removal of the old storage tank, mount the new tankless unit, connect water/gas/electric, and test the system in 4–8 hours. If upgrades such as a larger gas line, new vent penetration, or electrical circuit are required, the job may extend to a full day. We schedule a free on-site assessment beforehand so you know exactly how long your specific install will take.
Will a tankless water heater really lower my utility bills?
Yes. Because a tankless unit only fires when a fixture calls for hot water, it eliminates standby heat loss that storage tanks experience 24/7. In Greenback, the average household saves $80–$150 per year on natural gas and up to $200 on electric models—more if your current tank is older or poorly insulated. Over the 20-year life of a tankless heater, these savings typically exceed the higher upfront cost of the equipment and installation.
What size (flow rate) tankless water heater do I need for my Greenback home?
Sizing is based on two factors: 1) the maximum gallons per minute (GPM) of hot water your household will need at one time (showers, dishwasher, laundry, etc.) and 2) the temperature rise required, which in Greenback is roughly 60 °F (incoming water around 55 °F, desired 115 °F). A family of four that wants to run two showers and a washing machine at once will generally require a 9–11 GPM gas unit. During our consultation we calculate your peak demand and recommend the right size so you never run out of hot water.
Do I need to upgrade my gas line or electrical service for a tankless installation?
Often, yes. Modern gas units need a ¾-inch gas line capable of delivering 120–199 k Btu/h—larger than the ½-inch line many older tanks use. Electric tankless models may require 120–150 amps of dedicated 240-V power, which exceeds what most standard panels can spare. Our estimator checks line sizing, venting clearances, and electrical capacity during the site visit and provides a fixed price that includes any required upgrades to meet Tennessee and Blount/Loudon County codes.
How much maintenance does a tankless water heater need and do you offer service in Greenback?
Tankless units are low-maintenance, but they should be flushed once a year (twice if your water hardness exceeds 7 grains) to remove mineral buildup and keep the heat exchanger efficient. We offer an affordable annual maintenance plan covering descaling, filter cleaning, combustion check, and software diagnostics. Enrolling extends the manufacturer’s warranty, ensures peak efficiency, and gives you priority service from our Greenback plumbing team 24/7.
