FAQs
What are the main advantages of installing a tankless water heater in Crossville compared with a traditional storage-tank unit?
A tankless (on-demand) water heater heats water only when a fixture is opened, eliminating standby heat losses that occur with a storage tank. In Crossville’s moderate climate this can translate into 25–40 % lower annual energy use. Tankless models are wall-mounted, freeing up floor space, and they deliver an endless supply of hot water as long as the unit is properly sized. In addition, most units have a life expectancy of 20+ years—almost double that of a tank heater—so you save on replacement costs and reduce landfill waste.
How long does a professional tankless water heater installation usually take and will I be without water during the process?
For a straightforward replacement of an existing gas or electric tank heater, a licensed Crossville plumber can typically complete the job in 4–6 hours. A new installation that requires upsizing the gas line, adding venting, or upgrading the electrical circuit may take one full workday. Your water service is usually shut off for only 1–2 hours while we disconnect the old unit and tie the plumbing into the new one. We schedule installations at a time that minimizes disruption and always test the system before we leave.
Do I need a permit to install a tankless water heater in Crossville, TN, and who handles the code compliance?
Yes. Cumberland County and the City of Crossville both require permits for water heater replacements or new installations to ensure gas, electrical and venting work meets the 2021 International Residential Code and local amendments. As a licensed plumbing contractor we secure all necessary permits, coordinate the city inspection, and provide you with the final approval documentation for your records, so you don’t have to worry about paperwork or compliance issues.
What size tankless water heater should I buy for my household?
Sizing is based on maximum simultaneous hot-water demand (gallons per minute or GPM) and the temperature rise needed to reach 120 °F. In Crossville, ground-water temperature averages 55 °F, so you need roughly a 65 °F rise. A family of four that may run two showers (2 GPM each) and a dishwasher (1.5 GPM) at the same time would need a unit that can deliver about 5.5 GPM at a 65 °F rise—generally a 180,000 BTU gas unit or a 36 kW electric model. We perform a free in-home assessment to calculate your exact requirements and recommend the best unit for efficiency and comfort.
How much can I expect to save on energy bills with a tankless water heater?
According to the U.S. Department of Energy, homes that use 41 gallons of hot water or less per day can see energy savings of 24–34 % with a tankless system; heavier-use homes see 8–14 % savings. In practical terms, many Crossville homeowners report reducing their natural-gas bill by $8–$15 per month or their electric bill by $10–$20 after switching to tankless. Savings are higher when you pair the unit with low-flow fixtures and insulate hot-water lines.
What maintenance does a tankless water heater require and do you offer service plans?
Tankless units need annual maintenance to keep them performing efficiently, especially in Crossville where moderately hard water (5–7 grains per gallon) can cause scale buildup. The service includes flushing the heat exchanger with a mild vinegar solution, cleaning the inlet filter, and checking gas pressure, venting, and electrical connections. We offer an affordable yearly service plan that covers the tune-up, priority scheduling, and a 10 % discount on any repair parts, helping you protect your investment and maintain the manufacturer’s warranty.
