FAQs
How does a tankless water heater save energy compared to a traditional tank unit?
Traditional water heaters store 40–80 gallons of water and keep it hot around the clock, meaning they cycle on and off even when you are not using hot water. A tankless water heater only heats water when a fixture is opened, eliminating standby heat loss. In Dayton’s mixed-climate zone, that translates to 20–40 % lower energy consumption and utility savings of roughly $80–$150 per year for an average household.
What size (GPM rating) tankless unit do I need for my Dayton home?
Sizing is based on two factors: (1) the total flow rate of fixtures that might run simultaneously, and (2) the required temperature rise, which in Dayton averages 70 °F (groundwater ~50 °F, desired 120 °F). A typical three-bedroom, two-bath home usually needs a whole-house unit rated at 7–9 gallons-per-minute (GPM). Homes with large soaking tubs or multiple showers may require a 10–11 GPM unit or the installation of two smaller units in parallel. A professional load calculation ensures you never run out of hot water or overspend on an oversized model.
Are there local rebates or incentives for installing an energy-efficient tankless water heater in the Dayton area?
Yes. Dayton Power & Light (AES Ohio) periodically offers $100–$300 rebates for ENERGY STAR® certified gas tankless water heaters. Columbia Gas of Ohio also provides incentives on qualifying high-efficiency units. In addition, the federal Energy Efficient Home Improvement Tax Credit (25C) allows you to claim 30 % of the project cost—up to $600—for a qualifying gas tankless heater installed in 2023–2032. Our team will supply all model numbers and paperwork to make claiming these incentives easy.
What venting and gas line upgrades should I expect during installation?
Most gas tankless systems require ¾-inch gas piping to deliver the higher BTU input (150,000–200,000 BTU) needed for on-demand heating. If your existing line is ½-inch, we will upsize it or install a dedicated run from the meter. Venting uses sealed concentric PVC or stainless steel pipe and must terminate outdoors—often through a sidewall in Dayton homes with unfinished basements. We pull all necessary Montgomery County permits, follow ANSI Z223.1/NFPA 54 gas codes, and schedule the final city inspection so you are fully code-compliant.
How much maintenance does a tankless unit require and can I do it myself?
Tankless heaters need annual maintenance: flushing the heat exchanger with a vinegar or citric-acid solution to remove limescale, checking the inlet screen, and verifying combustion settings. Dayton’s moderately hard water (12–15 grains per gallon) makes descaling especially important. Many homeowners perform the flush themselves using a pump/hoses kit, but we offer an affordable service plan that covers the flush, gas calibration, and software update, preserving your 15-year manufacturer warranty.
Will a tankless water heater work during Dayton’s winter power outages?
Gas-fired tankless units still need a small amount of electricity (~50 W) for the control board and ignition. During a power outage they will not operate unless connected to backup power. A 1,000-watt portable generator or a whole-home standby generator will easily run the unit. Alternatively, a battery backup sized for a few hundred watt-hours can keep the water heater functional for several showers during short outages common to southwest Ohio storms.
