FAQs
How do I know if a tankless water heater is the right choice for my Louisville home?
A tankless water heater is ideal if you want endless hot water, lower energy bills, and extra space. Because Louisville experiences both hot summers and cold winters, choosing a properly-sized, high-efficiency condensing unit ensures dependable performance year-round. During our free in-home assessment, Right Capacity Plumbing evaluates your household’s peak demand, gas line size, venting path, and local water quality to confirm a tankless unit will meet your needs before we recommend installation.
What size (flow rate) tankless unit do I need?
Sizing is based on simultaneous fixture use and incoming water temperature. In Louisville, winter groundwater averages 50 °F, meaning the heater must raise water about 70 °F to reach a 120 °F setpoint. We total the gallons-per-minute (GPM) for all fixtures you might run at once—typically 8–10 GPM for a three-bath home. We then match that demand with a unit capable of a 70 °F rise at that flow. Right Capacity Plumbing uses load-calculation software and manufacturer specs to choose the correct BTU and GPM rating so you never run out of hot water.
How long does a professional tankless installation take?
Most residential swaps from a standard tank to a gas tankless system take 6–8 hours. This includes removing the old tank, upgrading the gas line (often to ¾"), installing Category III or PVC venting, adding a condensate drain, mounting the unit, and testing for leaks. Complex relocations or electrical upgrades can extend the job to one full day. We schedule installations at your convenience and always file the required Louisville Metro permits.
Will a tankless water heater lower my energy bills?
Yes. Traditional storage heaters keep 40–50 gallons hot 24/7, leading to standby losses. A high-efficiency (up to 0.97 UEF) tankless unit only fires when you open a tap, saving 20–40 % on gas costs for a typical Louisville family. Over the 20-year life of a tankless system, those savings often exceed the initial price difference compared with a tank unit.
What maintenance does a tankless water heater require in Kentucky?
Hard water in the Louisville area (12–15 grains per gallon) can cause scale buildup. We recommend annual flushing with a vinegar solution or a manufacturer-approved descaling product. Right Capacity Plumbing offers an affordable maintenance plan that includes flushing, filter cleaning, gas combustion check, and software updates. Regular service maintains efficiency, extends warranty coverage, and helps you avoid costly repairs.
Are rebates or financing available for tankless installations in Louisville?
Yes. Many ENERGY STAR tankless models qualify for a federal tax credit of up to 30 % of project cost (max $600). Louisville Gas & Electric (LG&E) periodically offers $250–$400 rebates for high-efficiency natural-gas appliances. Right Capacity Plumbing handles the paperwork and can bundle rebates with 0 % or low-interest financing through our partners, letting you upgrade with little or no upfront cash.
