FAQs
How does a tankless water heater provide endless hot water?
Unlike traditional storage tanks that heat a limited volume of water and then wait to re-heat, a tankless (on-demand) water heater activates only when a hot-water tap is opened. Cold water flows across high-efficiency heat exchangers powered by gas or electricity, raising the temperature instantly. Because the unit heats water continuously as it passes through, it can supply hot water for as long as the fixture is running—no storage tank means no running out.
Is a tankless water heater right for my Corryton home?
Most Corryton homes are excellent candidates, especially if you have ¾" gas lines, adequate venting options, and a 200-amp electrical panel (for electric models). We perform a free on-site assessment to check gas supply, water quality, water pressure, and the number of simultaneous fixtures you typically use. Even older homes can usually be retrofitted with minimal modifications.
What are the installation costs and potential savings?
Installed pricing in the Corryton area generally ranges from $3,200–$4,800 for a high-efficiency gas unit, including permits, venting, water treatment, and labor. Electric units start around $2,100. Although the upfront price is higher than a conventional tank, ENERGY STAR® tankless models are 24%–34% more efficient, often saving $80–$120 per year on utility bills. With proper maintenance, they last 20+ years—about twice the lifespan of a tank—so lifetime cost is typically lower.
How long does the installation take and will I be without water?
Most replacements are completed in a single day (6–8 hours). We shut off your water and gas only during the final tie-in, usually for 1–2 hours. If new venting or gas line upgrades are required, we stage those tasks to minimize downtime. You’ll have full water service before we leave the job site.
What maintenance does a tankless water heater need?
To keep your warranty valid and maintain efficiency, we recommend an annual service that includes descaling the heat exchanger, cleaning the inlet filter, checking gas pressure, and updating firmware on newer smart models. In Corryton’s moderate-hard water, descaling is especially important; we can install a small, affordable scale-inhibitor filter to reduce mineral buildup between services.
Are there rebates or incentives available in Corryton?
Yes. Tennessee homeowners may qualify for a federal 30% tax credit (up to $600) on ENERGY STAR®-certified gas and electric tankless units. Knoxville Utilities Board (KUB) also offers occasional bill credits or low-interest financing for high-efficiency water heaters. We handle the paperwork and provide all model and installation documentation you need to claim these incentives.
