FAQs
How much can I save on energy bills with a tankless water heater in Decatur?
Because tankless units heat water only when you turn on the tap, they eliminate the standby losses of a storage tank. In Decatur’s climate and utility-rate structure, homeowners typically cut water-heating costs 20–40 %, or about $80–$150 per year for a family of four. The exact savings depend on your hot-water use, the unit’s Energy Factor rating, and whether you choose natural-gas or electric.
Is my Decatur home compatible with a tankless water heater installation?
In most cases, yes, but a quick site inspection confirms it. Gas models need a ¾″ gas line (sometimes upsized from ½″), a Category III or IV vent through an outside wall or roof, and a nearby 120-V outlet for the electronics. Electric models may need 150–200 A service and two to three dedicated 40- to 50-amp breakers. We also check water hardness (above 8 gpg calls for a scale filter) and locate an exterior wall for easy venting or condensate drain. Our technicians handle all permitting with the City of Decatur and ensure the installation meets local mechanical and plumbing codes.
What size tankless water heater do I need for my household?
Sizing is based on simultaneous flow rate (gallons per minute) and the temperature rise between incoming ground water and your desired hot-water set point. Decatur’s incoming water averages 60 °F. To supply two showers and a washing machine at once (≈7 GPM) and raise the temperature to 120 °F, you’d look for a gas unit around 180–199 kBTU/h or an electric unit in the 24–27 kW range. We perform a detailed load calculation during the estimate to choose the exact model.
How long does installation take and will I be without hot water?
Most replacements are completed in one working day (4–8 hours). We shut off your old water heater, disconnect utilities, mount and vent the new unit, run gas or electrical upgrades, and commission the system. Hot water is unavailable only during the swap—usually 2–4 hours. We coordinate scheduling so you’re never without hot water overnight.
What maintenance does a tankless water heater require and how often?
A yearly service keeps efficiency high and protects the heat exchanger. We flush the unit with a vinegar or citric-acid solution to remove scale, clean the inlet screen, and check venting, gas pressure, and condensate lines. If your water hardness exceeds 12 gpg, we recommend flushing every six months or adding a whole-house conditioner. Maintenance takes about one hour and costs far less than repairing a scaled heat exchanger.
Are there rebates or tax incentives available in Decatur for upgrading to a tankless unit?
Yes. Atlanta Gas Light currently offers a $400 rebate for ENERGY STAR® natural-gas tankless installations, and Georgia Power provides a $75 bill credit for qualifying electric models. On the federal level, the Inflation Reduction Act extends a 30 % tax credit (up to $600) on high-efficiency water heaters through 2032. We supply all paperwork and model numbers so you can claim local utility rebates and federal incentives.
