FAQs
How does a tankless (on-demand) water heater work and what benefits does it offer Alcoa homeowners?
A tankless unit senses water flow the moment you open a hot-water tap. A powerful gas burner or electric element instantly heats the water as it passes through a heat exchanger, delivering a continuous supply of hot water until you close the tap. Because there is no storage tank, you avoid standby heat loss, which can cut water-heating energy use by 25–40 %. For Alcoa residents, that means lower utility bills, freed-up floor space, and no risk of a ruptured tank flooding your basement.
What size tankless water heater do I need for my household in Alcoa?
Sizing is based on two factors: (1) the flow rate of the fixtures you want to run simultaneously (measured in gallons per minute, or GPM) and (2) the temperature rise required, which in Alcoa is typically 70 °F (groundwater averages 55 °F; you generally want 120–125 °F hot water). A typical family of four that may run two showers and a kitchen sink at once needs roughly 7–9 GPM. Our technicians calculate your home’s exact peak demand and recommend a unit that can reliably meet it without short-cycling or overheating.
Is a gas or electric tankless heater better for my Alcoa home?
Both work well, but each has trade-offs: • Natural gas/propane models deliver higher flow rates (up to 11 GPM) and handle multiple fixtures better. They do, however, require proper venting and, if propane, on-site storage. • Electric units are compact, vent-free, and easier to install, but they need large electrical service (often 150–200 A total for the home) and may struggle to serve more than one major fixture at a time. We review your utility availability, existing gas line or panel capacity, and hot-water demand to help you choose the most cost-effective option.
What is involved in the installation process and how long will it take?
1. In-home assessment to confirm sizing, venting path, gas/electrical requirements, and permit needs. 2. Permit application with the City of Alcoa Building & Codes Department (usually 1–2 business days). 3. Installation day: we shut off water and utilities, remove the old tank, mount the new unit on a wall, run vent and fresh-air piping (for gas models), upgrade gas/electrical lines as needed, and connect water lines with isolation valves and flush ports. 4. System start-up, combustion or electrical testing, leak check, and demonstration. Most jobs take 4–8 hours, and you are without water for only a small portion of that time.
Are there local codes or permits required for a tankless water heater installation in Alcoa?
Yes. The City of Alcoa and Blount County follow the International Residential Code (IRC). A mechanical or plumbing permit is required for gas lines, venting, and water piping changes; an electrical permit is needed if circuit upgrades are performed. Our licensed plumbers pull all necessary permits, schedule inspections, and provide the homeowner with final approval documents so you stay fully code-compliant and maintain warranty coverage.
How much maintenance does a tankless unit need and how long will it last?
With proper care, a quality tankless heater lasts 20–25 years—roughly double the lifespan of a tank. Because Alcoa’s water is moderately hard (about 4–6 grains per gallon), we recommend a yearly service that includes descaling the heat exchanger with a vinegar solution, cleaning the inlet screen, and checking venting and combustion. We install isolation valves to make flushing quick and mess-free, or you can enroll in our affordable annual maintenance plan to keep warranty requirements intact and efficiency high.
