FAQs
How much can I expect to save on energy bills with a tankless water heater in Louisville?
Most Louisville homeowners see energy-cost reductions of 20–40 % compared with a standard storage tank. Because a tankless unit heats water only when a tap is opened, it eliminates the 24/7 standby losses of a tank. Savings vary with water-use habits, unit efficiency (look for a UEF of 0.90 or higher), incoming groundwater temperature, and gas or electric rates in Jefferson County.
Is Louisville’s water quality and climate suitable for a tankless water heater?
Yes. Louisville’s municipal supply is moderately hard (12–16 grains per gallon), so most manufacturers simply recommend an annual flush with white vinegar to remove mineral scale. The climate’s wide temperature swings are automatically handled by a modern modulating burner; installers will size the unit based on winter groundwater temps (about 52 °F) to ensure you still get full-flow hot water on the coldest days.
What size tankless unit do I need for my home?
Sizing is based on simultaneous demand (gallons per minute) and required temperature rise. A typical three-bath Louisville home needs 7–9 GPM at a 68 °F rise, which translates to a 180,000 BTU natural-gas model. Smaller condos may only need 140,000 BTU (5 GPM). A site visit lets us tally fixtures, measure water pressure, and check gas-line capacity before recommending the right model.
How long does installation take and will my plumbing need upgrades?
Most retrofits are completed in one day. We mount the wall-hung unit, relocate water lines, and add a condensate drain. Because tankless models require higher BTU input, we often upsize the gas line to ¾ in. or install a dedicated 240-V circuit for electric units. Venting changes to sealed stainless or PVC are also handled during the same visit. You’ll have hot water again before dinner.
What maintenance does a tankless water heater require?
Annual service is quick: we flush the heat exchanger with a vinegar or citric solution for 30–45 minutes, clean the air intake filter, and run a diagnostic. Homeowners can handle basic filter rinsing themselves, but the yearly flush preserves the warranty and keeps efficiency high. With routine care, tankless units last 20+ years—about twice the lifespan of a storage tank heater.
Are there rebates or incentives for installing a tankless water heater in Louisville or Kentucky?
Yes. Louisville Gas & Electric (LG&E) customers can receive a $200 bill credit for qualifying ENERGY STAR® gas tankless models. Kentucky residents may also claim the federal 25C tax credit—30 % of the installed cost up to $600—through 2032. We provide all compliance paperwork and model numbers so you can easily file for both the utility rebate and federal tax incentive.
