FAQs
What are the main advantages of switching to a tankless water heater over a traditional storage-tank heater?
Tankless units heat water on demand, so you never run out of hot water and eliminate stand-by heat loss from a storage tank. In Elizabethton, that typically lowers energy use by 20–40 %, which can translate into noticeable savings on your utility bill. Tankless models are also compact, freeing up floor space, and have a life expectancy of 20+ years—about twice that of a conventional tank. Certified installation ensures the unit is properly sized and vented, maximizing performance and safety.
Is a tankless water heater a good fit for homes in Elizabethton’s climate and water conditions?
Yes. Our region’s incoming water temperature averages 50–55 °F in winter and 60–65 °F in summer, well within the operating range of modern gas and electric tankless units. Our certified technicians measure your home’s flow-rate demand and temperature rise to match you with a model that maintains steady output even on the coldest days. We also test local water hardness; if it exceeds 7 gpg, we recommend and can install a small scale-reduction filter to protect the heat exchanger.
How long does a professional tankless water heater installation take and what should I expect?
A straightforward replacement of a gas tank water heater with a gas tankless unit usually takes 4–6 hours. The process includes: 1) safely draining and removing the old tank, 2) upgrading gas line size if needed for higher BTU demand, 3) installing Category III/IV venting or an outdoor direct-vent model, 4) mounting the unit and connecting water, gas, condensate and electrical lines, and 5) commissioning the system (combustion analysis, leak check, programming). Homes converting from electric to gas, or moving the unit to a new location, may take a full day. Our technicians pull required city permits and arrange final inspection with Elizabethton Codes Enforcement.
What size (flow rate) tankless water heater do I need?
Sizing is based on two factors: the maximum gallons-per-minute (GPM) you’ll need during peak use and the temperature rise between incoming cold water and your desired hot-water set-point (usually 120 °F). For example, if you regularly run a shower (2.0 GPM) and dishwasher (1.5 GPM) at the same time, you need at least 3.5 GPM at a 60–70 °F rise in winter. We perform a detailed fixture count, review simultaneous use habits, and select a unit—often 160–199 kBTU for gas or 18–27 kW for electric—that delivers that flow without dropping below 120 °F. Proper sizing prevents ‘cold-water sandwich’ issues and maximizes efficiency.
What maintenance does a tankless water heater require and do you offer service plans?
Manufacturers recommend an annual inspection to keep the warranty valid. Our maintenance includes descaling the heat exchanger with food-grade vinegar or citric solution, cleaning the combustion chamber and fan, flushing the condensate trap, checking gas-pressure and CO levels, and updating firmware on smart models. In areas with moderate hardness, we may suggest servicing every 18–24 months instead of annually. We offer affordable service agreements that provide priority scheduling, discounted parts, and 24/7 emergency support from our certified technicians.
Are there rebates, tax credits, or financing options available for tankless water heaters in Elizabethton?
Yes. Tennessee homeowners can currently claim a 30 % federal tax credit (capped at $600) for qualifying ENERGY STAR gas tankless units installed in 2023–2032. Local utility BrightRidge offers up to $300 in rebates for high-efficiency electric models. We’re a TVA EnergyRight partner, so we handle the paperwork and apply the rebate as an instant discount. We also provide 0 % APR financing for 12 months or low-interest plans up to 60 months (subject to credit approval) so you can spread the investment over manageable payments.
