FAQs
How does a tankless water heater work and what advantages does it offer over a traditional storage tank?
A tankless (on-demand) water heater uses high-efficient gas burners or electric elements to heat water only when a hot-water tap is opened. Because it doesn’t keep 40–50 gallons of water hot all day, it eliminates standby heat loss, cuts energy use by 20-40 %, and can provide an endless supply of hot water as long as the unit’s flow-rate capacity is not exceeded. Tankless models are also more compact, have a service life of 20+ years (about twice that of a tank), and reduce the risk of a catastrophic tank leak.
Is a tankless water heater a good fit for my home in Seymour?
In most Seymour homes the answer is yes, but a short site visit helps us confirm. We look at your household’s peak hot-water demand, available natural-gas or electrical service, venting routes, and water hardness. Modern condensing tankless units operate efficiently in our Mid-Indiana climate, and outdoor-rated models can be used if the heater is mounted within the home’s heated envelope or a freeze-protection kit is added. Homes with 3 or more simultaneous hot-water uses (e.g., shower + dishwasher + laundry) may need either a higher-capacity unit or two smaller units in parallel.
What size tankless unit do I need?
Sizing is based on flow rate (gallons per minute, GPM) and temperature rise—the difference between incoming groundwater temperature (about 50 °F in Seymour most of the year) and the desired hot-water temperature (120 °F). For example: a shower (2.0 GPM) + kitchen sink (1.5 GPM) running together require roughly 3.5 GPM at a 70 °F rise. We add a safety margin and recommend a 7–9 GPM gas unit for most three-bath homes, while smaller households often do well with a 5–6 GPM model. Electric tankless units may be viable for one-bath dwellings but typically need a 150–200 A electrical service.
How long does installation take and what is involved?
A straightforward replacement of a gas tank with a gas tankless heater usually takes one working day. The process includes: (1) draining and removing the old tank, (2) upgrading the gas line to the higher BTU demand if necessary, (3) installing stainless-steel or PVC venting through an exterior wall or roof, (4) mounting the tankless unit and connecting water lines with isolation/flush valves, (5) purging air, testing for leaks, and setting temperature, and (6) hauling away the old unit. Electric models often require new breakers and wiring, which we coordinate with a licensed electrician and the city inspector.
What regular maintenance does a tankless heater need?
To keep efficiency high and maintain the manufacturer’s warranty, flush the heat exchanger with a vinegar or citric-acid solution once a year (every 6 months if your water is very hard). Our plumbers install service valves that make this a quick 45-minute job. We also recommend cleaning the inlet screen filter twice a year and checking the vent termination for debris. During an annual service visit we inspect gas pressure, condensate drain, and controller diagnostics to catch small issues before they become costly repairs.
Are there rebates or energy-savings incentives available in Seymour?
Yes. Jackson County REMC and Duke Energy customers can qualify for $150–$300 rebates on ENERGY STAR® certified gas tankless models. Indiana’s NIPSCO gas customers may receive up to $400. Additionally, the federal Energy Efficient Home Improvement Credit (Section 25C) allows a tax credit of 30 % of the installed cost, up to $600, for qualifying units placed in service after January 1, 2023. We handle all paperwork, provide AHRI certificates, and guide you through local permit requirements so you capture every available savings.
