FAQs
What are the main advantages of installing a tankless water heater in my Dayton home?
Tankless (on-demand) units heat water only when you open a tap, eliminating the standby losses of traditional storage tanks. Homeowners in the Dayton area typically see energy-use reductions of 20–40 %, saving $80–$200 per year on utility bills. You also gain unlimited hot-water supply, a unit that lasts 18–20 years (versus 10–12 for tanks), and about 12–15 ft² of recovered floor space—an important perk in older Miami Valley basements and utility closets.
How do I know what size tankless water heater I need?
Sizing is based on flow rate (gallons per minute) and temperature rise. In Dayton, incoming groundwater averages 50–55 °F in winter, so to reach a comfortable 120 °F you need a 65- to 70-degree rise. Add up the simultaneous fixtures you want to run—for example, a shower (2 gpm) plus a dishwasher (1.5 gpm) equals 3.5 gpm. We calculate this during a free in-home evaluation and recommend the proper BTU rating (150k–199k for gas or 18–36 kW for electric) to ensure you never run out of hot water even on the coldest February morning.
What does a professional tankless installation cost in the Dayton market, and how long does it take?
For most single-family homes, fully-installed pricing—including the unit, venting, gas or electrical upgrades, and permit fees—ranges from $3,200 to $4,800 for gas models and $2,800 to $4,200 for electric. Complex retrofits (long vent runs, major gas-line upsizing) can add $500–$1,000. A straightforward replacement takes 4–6 hours; first-time conversions usually finish within one business day. We provide firm, up-front quotes so there are no surprises.
Do I need a permit or inspection to install a tankless water heater in Dayton?
Yes. The City of Dayton and surrounding townships classify water-heater replacement as a regulated plumbing alteration. A licensed Ohio plumber must pull a mechanical/plumbing permit, and a city or county inspector will verify gas-line sizing, vent termination, electrical bonding, and pressure relief discharge before final approval. We handle the entire permitting process and schedule inspections to ensure your installation is 100 % code-compliant.
Dayton has moderately hard water—will that damage a tankless unit?
The Miami Valley’s water averages 9–12 grains of hardness. Mineral scale can reduce efficiency and eventually clog the heat exchanger. We include a stainless isolation valve kit so the heater can be descaled annually. A quick 45-minute vinegar or citric-acid flush keeps the unit running at peak performance and preserves the manufacturer’s 12- to 15-year heat-exchanger warranty. Homes above 15 grains benefit from a whole-house softener, which we can install at the same visit.
Can a tankless water heater use my existing natural-gas or electrical service?
Gas units need ¾-inch—or sometimes 1-inch—gas lines delivering 150,000–199,000 BTU/h, plus Category III or IV stainless venting. Many post-1990 Dayton homes already meet these specs; older properties may require gas-line upsizing or a dedicated 2-inch PVC vent through the rim-joist. Electric models draw 18–36 kW and require two to four 40-amp, 240-volt breakers and #8 copper conductors. During our site survey we measure gas pressure, inspect your panel capacity, and quote any upgrades so your system meets code and performs flawlessly.
