FAQs
Why should I choose a tankless water heater instead of a storage-tank model for my Greenback home?
Tankless units heat water on demand, so you never run out of hot water and you avoid the standby heat loss common with storage tanks. In Greenback’s mild climate, the incoming water temperature is moderate, which allows tankless heaters to operate very efficiently. Homeowners typically gain 20–40% energy savings, reclaim closet or garage space, and enjoy a product life expectancy of 20+ years—almost double that of a tank unit.
How long does a professional tankless water heater installation take?
Most single-family installations are completed in one day. Our Greenback plumbing team arrives with the unit, venting materials, gas or electrical fittings, and any required permits already in hand. We begin by isolating and removing your old tank, upgrading gas or electrical lines if necessary, hanging and venting the new unit, and then testing for leaks and proper flow. Complex projects—such as relocating the heater or integrating a recirculation loop—can extend the timeline to two days, but we will outline the schedule for you in advance.
What size (flow rate) tankless water heater do I need?
Sizing is based on the peak gallons-per-minute (GPM) demand in your home and the temperature rise needed. In Greenback, groundwater averages about 55 °F. If you want 120 °F at the tap, that’s a 65 °F rise. We’ll add up the fixtures you might run simultaneously—e.g., two showers (2.0 GPM each) and a dishwasher (1.5 GPM) equals 5.5 GPM. We’d recommend a 6–7 GPM unit to cover that demand with some margin. Our technicians perform this calculation during a free in-home assessment to guarantee the correct model.
Will a tankless water heater really lower my utility bills?
Yes. Because tankless units only fire when you open a hot-water tap, they avoid the round-the-clock standby heat losses of storage tanks. ENERGY STAR data show an average household saves roughly $100 per year (gas) or $44 per year (electric). Many Greenback customers report 20–40% reductions on their gas bills. Over a 20-year lifespan, the savings offset the higher upfront cost and can exceed $2,000, especially if you also qualify for the current federal tax credit of up to $600 for high-efficiency equipment.
What maintenance does a tankless water heater require, and do you offer service plans?
An annual flush with food-grade vinegar or a manufacturer-approved descaling solution removes mineral buildup and keeps the heat exchanger efficient—especially important with the moderately hard water in Loudon County. We also clean the inlet filter, check venting, and perform a combustion analysis. Our Greenback service plan covers this yearly maintenance, extends the labor warranty to five years, and provides priority scheduling should you ever need repairs.
Do I need to upgrade my gas line or electrical service for a tankless installation?
Possibly. Gas tankless units often require ¾-inch gas lines and a higher BTU input (150k–199k BTU) than many tank heaters. We evaluate your existing line size, meter capacity, and regulator. If an upgrade is needed, we handle permitting and installation. Electric tankless models demand 120–150 amps of dedicated 240-V service, which many older Greenback homes lack. Our licensed electricians can add sub-panels or service upgrades as part of the project so your new water heater operates safely and efficiently.
