Because a water heater is only as reliable as the system that feeds it, we also inspect surrounding plumbing to catch hidden leaks, corrosion, or venting issues before they turn into costly surprises.

FAQs
What types of water heaters do you install in the Dayton area?
Our licensed plumbers install all major styles, including traditional gas and electric tank-type units (30–120 gallons), high-efficiency condensing gas models, electric hybrid heat-pump heaters, and on-demand tankless systems. We work with leading brands such as Bradford White, Rheem, A. O. Smith, and Navien, so we can match the unit’s fuel type, efficiency rating, and capacity to your household’s needs and local utility rates.
How long does a typical water-heater installation take?
For a straightforward replacement of a similar tank-style heater, the job generally takes 2–4 hours: 30–60 minutes to drain and remove the old unit, about an hour to set and level the new heater, and another hour to complete gas, water, and vent connections, bring the unit up to temperature, and perform the final safety check. Converting to a different fuel source or installing a tankless system can extend the project to one full day because we may have to upsize gas lines, reroute venting, or run a new 240-volt circuit.
How do I know what size water heater is right for my home?
We size water heaters by looking at peak-hour demand, which is the greatest amount of hot water your household uses in any single hour. For tank units we compare that figure to the heater’s first-hour rating (FHR). As a rule of thumb, a family of 2–3 in Dayton usually needs a 40-gallon gas or 50-gallon electric tank, while 4–5 people often require 50–60 gallons. Tankless models are sized by flow rate—gallons per minute at a 70 °F rise—so we calculate how many fixtures you want to run at once and the winter groundwater temperature here (around 48 °F). During your free estimate we take these factors, along with space constraints and energy-efficiency goals, into account to recommend the ideal unit.
Do I need a permit to replace my water heater in Dayton, and will you handle it?
Yes. The City of Dayton and surrounding Montgomery County townships require a mechanical permit for any water-heater replacement, whether tank or tankless. This ensures the unit meets current plumbing, gas, and venting codes for safety and efficiency. We take care of the entire permitting process—application, fee payment, scheduling the inspection, and meeting with the inspector—so you don’t have to. Once the job passes inspection, you’ll receive the final approval paperwork for your records.
Can you provide same-day or emergency water-heater installation?
Absolutely. Our technicians are on call 24/7 for no-hot-water emergencies. If you call before noon, we can usually secure the permit, pick up the correct replacement unit from our local supplier, and have hot water restored the same day. After-hours and weekend installations are available for an additional service fee, which we discuss up-front so there are no surprises.
What warranties and maintenance options do you offer?
All new water heaters we install come with the manufacturer’s tank and parts warranty—typically 6- to 12-year coverage for tanks and heat exchangers, plus 1-year parts. Our labor is warrantied for a full year. You can extend protection with our optional Comfort Club plan, which includes an annual flush, anode-rod check, combustion analysis (gas units), and priority service. Regular maintenance can double the lifespan of a tank-type heater and keeps tankless units free of mineral buildup common in Dayton’s moderately hard water.
