FAQs
Why should I choose a tankless water heater for my Collegedale home?
Tankless units heat water on demand, eliminating the standby heat loss associated with storage tanks. That means lower energy bills, unlimited hot water, a smaller footprint, and equipment that can last 20+ years when properly maintained. In Collegedale’s climate, where winters are mild but chilly, a properly sized gas or electric tankless heater delivers efficient performance year-round.
How do I know what size (GPM) tankless water heater I need?
Sizing is based on the total gallons per minute (GPM) of hot water your household may demand at peak times plus the temperature rise needed. In Collegedale, incoming groundwater averages 55-60 °F. If you want 120 °F water, you need a 60-65 °F rise. Add up simultaneous fixtures—for example, shower (2.0 GPM) + dishwasher (1.5 GPM) = 3.5 GPM. We perform an in-home assessment to recommend a unit that meets or exceeds that flow with buffer capacity.
What is involved in converting from a traditional tank to a tankless system?
A licensed plumber will: (1) turn off utilities and drain the old tank; (2) remove the tank and repurpose the space; (3) upgrade gas lines or electrical circuits if necessary; (4) install venting (for gas models) through an exterior wall or roof; (5) mount the compact tankless unit; (6) connect water, gas/electric, and condensate drain lines; (7) test for leaks and proper operation; and (8) register the warranty. Most conversions in Collegedale take 4–8 hours.
Will a tankless water heater save me money on energy bills?
Yes. Because water is heated only when you open a tap, tankless systems can reduce energy use by 24–34 % over traditional storage heaters (U.S. DOE data). Savings vary with household size and water use habits, but Collegedale homeowners typically report $80–$150 annual reductions, offsetting the higher upfront cost over 5–7 years.
Do tankless water heaters require maintenance?
Annual maintenance is recommended: flushing the heat exchanger to remove mineral buildup, cleaning the inlet filter, and inspecting venting and gas pressure. Collegedale’s moderately hard water (average 6–8 grains per gallon) makes descaling especially important. Our service plans include a yearly visit that keeps the warranty valid and ensures peak efficiency.
Are there rebates or incentives for installing a tankless water heater in Collegedale?
Yes. Tennessee Valley Authority (TVA) energy-efficiency programs occasionally offer cash incentives for qualifying ENERGY STAR® gas tankless units. Federal tax credits of 30 % (up to $600) are available through 2032 for high-efficiency models. We handle the paperwork and provide the documentation you need to claim local utility rebates and federal credits.
