FAQs
What are the main advantages of installing a high-efficiency tankless water heater in my Greenback home?
Tankless units heat water only when you open a tap, eliminating standby heat loss and cutting energy use by 20–40 %. They also deliver endless hot water, free up floor space, and typically last 18–20 years—about twice the life of a conventional tank. In Greenback’s climate, these benefits translate to lower monthly utility bills and a reduced carbon footprint.
How do I know what size tankless water heater I need?
Sizing is based on two factors: the maximum flow rate you’ll need at one time and the temperature rise required. We calculate the combined gallons-per-minute demand of fixtures you may run simultaneously (e.g., shower + dishwasher) and compare it to the incoming groundwater temperature in Greenback, which averages 58 °F. For most households, a unit rated at 7–9 GPM is sufficient, but larger homes or those with multiple luxury showers may need 11 GPM or more. We perform a free on-site assessment to recommend the right model.
What is involved in the installation process and how long does it take?
A typical retrofit takes 4–8 hours. We remove the old tank, install wall mounting brackets, upgrade gas or electrical service if required, add dedicated venting, and connect water and condensate lines. Our technicians pull any necessary Greenback permits and ensure the system meets local plumbing and mechanical codes. You’ll have hot water again by the end of the day.
Will my existing gas line or electrical panel need upgrades?
Possibly. Gas-fired units require a larger BTU input (150k–199k BTU) and often need a ¾-inch gas line. Electric models need a 120–200 A panel with multiple 40–50 A breakers. During our site visit we test line pressure, measure wire gauge, and give you a written quote for any upgrades so there are no surprises.
How much maintenance does a tankless system require?
Plan on a simple annual tune-up: flushing the heat exchanger with food-grade vinegar to remove scale, cleaning the inlet filter, and checking venting. Hard water in the Greenback area can accelerate mineral buildup, so some homeowners install a water softener or a scale-inhibiting filter. With regular service, your unit should run at peak efficiency for two decades.
What rebates or incentives are available in Greenback for high-efficiency tankless water heaters?
Many Greenback residents qualify for federal tax credits of up to 30 % of the project cost (capped at $600) under the Inflation Reduction Act. Tennessee Valley Authority (TVA) occasionally offers $100–$200 rebates for ENERGY STAR® models. We provide the paperwork and AHRI certificates needed to claim any incentives and will alert you to current local programs before you commit.
