FAQs
What are the main benefits of switching from a traditional storage tank to a tankless water heater in Dandridge?
A tankless (on-demand) unit heats water only when you open a tap, so it eliminates standby heat loss and can cut water-heating energy use by 25–40 %. Many homeowners enjoy endless hot water for back-to-back showers, a smaller wall-mounted footprint that frees up floor space, and a life span that averages 20+ years (about twice that of a tank). Because our certified plumbers size and vent every system to local codes, you also gain better safety, lower risk of leaks, and higher resale value.
How do I know what size or flow-rate (GPM) tankless water heater my home needs?
The right size depends on (1) the number of fixtures you expect to run simultaneously and (2) Dandridge’s average groundwater temperature, which is about 55 °F. We add the flow rates of your highest-demand combination—for example, one shower (2.0 GPM) + a dishwasher (1.5 GPM) + a sink (1.0 GPM) = 4.5 GPM—then determine the temperature rise needed to reach 120 °F. A certified plumber uses a sizing chart to match those figures to a unit typically in the 7–11 GPM range for most three-bedroom homes. A free on-site consultation ensures you neither over- nor under-buy.
What is involved in a professional installation, and how long will it take?
Most installs are completed in one working day. Our crew first turns off water, gas, and power to remove your old tank. We then mount the tankless unit on an exterior or interior wall, upsize gas lines or upgrade electrical circuits if needed, install stainless-steel or PVC venting, add a condensate drain, and connect water, gas/electric, and control wiring. Before we leave, we flush the lines, calibrate the thermostat, test for gas leaks and carbon-monoxide levels, and show you how to use the controls. All work is performed by state-licensed, fully insured plumbers and passes a final city or county inspection.
Do I need a permit for a tankless water heater in Dandridge, and will you handle it?
Yes. Jefferson County and the City of Dandridge require plumbing and, for gas units, mechanical permits. Electrical upgrades also need an inspection by the local utility. Our office pulls every permit, schedules rough-in and final inspections, and provides the paperwork for your records, so you stay fully code-compliant without lifting a finger.
How much does a tankless water heater installation typically cost, and are there any Tennessee rebates or tax credits?
Installed prices in Dandridge generally range from $3,200 to $4,900, depending on fuel type (natural gas, propane, or electric), capacity, venting distance, and any gas-line or electrical upgrades. Tennessee homeowners can claim up to a $2,000 federal tax credit on qualifying ENERGY STAR® equipment through 2032. Local utilities such as TVA and Newport Utilities occasionally offer $100–$300 rebates—ask us for the current list. Because a tankless unit can save $80–$150 a year on energy bills, most systems pay for themselves in 6–8 years.
What kind of maintenance does a tankless water heater need, and can your team provide it?
To keep warranty coverage valid, manufacturers recommend an annual service: descaling the heat exchanger with food-grade vinegar (especially important with East Tennessee’s moderately hard water), cleaning the inlet filter, checking the burner or heating elements, and verifying venting integrity. Our plumbing company offers affordable maintenance plans that include a reminder call, a full safety inspection, and a written health report. Regular upkeep prevents mineral buildup, maintains efficiency, and can extend the life of the unit well past 20 years.
