FAQs
What are the benefits of installing a tankless water heater in my Blountville home?
Tankless units heat water on demand, so you never run out of hot water. They’re typically 20–40 % more energy-efficient than storage tanks, take up less space, and often last 20+ years (about twice as long as traditional tanks). In Blountville’s variable climate, this means lower utility bills, consistent hot-water delivery for multiple fixtures, and less maintenance over the long term.
How do I know what size (GPM) tankless water heater I need?
Sizing is based on peak demand in gallons per minute (GPM) and the temperature rise required. We’ll total the flow rates of fixtures you might run simultaneously (for example, a shower at 2.5 GPM plus a kitchen sink at 1.5 GPM = 4 GPM). Then we factor in Blountville’s average incoming water temperature (about 55 °F) and the desired outlet temperature (typically 120 °F), giving a 65 °F rise. Using these numbers we select a unit—often in the 6–9 GPM range for most three-bathroom homes. A professional load calculation ensures you get a model that won’t short-cycle or leave you with lukewarm water.
Can a tankless water heater be installed in place of my existing tank without major changes?
In many Blountville homes, yes, but some upgrades are common. Tankless units require a dedicated gas line (often ¾" or larger) or a 240-V electrical circuit with higher amperage if electric. Venting must be stainless steel or PVC direct-vent, which differs from standard water-heater flues. Our installers evaluate gas supply, vent route, condensate drain, water lines, and mounting location to minimize structural changes while meeting code.
How long does a professional tankless installation take?
Most replacements are completed the same day. A straightforward gas tank-to-gas tankless swap can take 4–6 hours. If significant gas line upsizing, venting through masonry, or electrical work is needed, it may extend to 8–10 hours or require a second visit. We provide a detailed timeline up front so you know exactly what to expect.
What maintenance does my new tankless unit require?
Tankless heaters need annual flushing with a vinegar or descaling solution to remove mineral buildup, especially with Blountville’s moderately hard water. The installer will include service valves for easy flushing. You should also clean the inlet screen filter every 6–12 months, check vent termination for debris, and have combustion settings inspected professionally every 2–3 years to maintain warranty coverage.
Are there local rebates or tax incentives for choosing a tankless water heater in Blountville?
Yes. Many Energy Star–qualified gas tankless models are eligible for a 30 % federal tax credit (up to $600) under the Inflation Reduction Act. Tennessee’s TVA EnergyRight program sometimes offers cash incentives for high-efficiency upgrades, and we’ll handle the paperwork. Additionally, certain utility providers in Sullivan County give bill credits for lowering natural-gas consumption. Ask us for the latest incentive list when you request your quote.
