FAQs
What are the main advantages of choosing a high-efficiency tankless water heater for my Corryton home?
Tankless units heat water on demand, so you’re not paying to keep 40–50 gallons hot all day. This can cut water-heating energy use by 25–40 %, extend equipment life to 20+ years, free up floor space, and provide an endless supply of hot water as long as the unit is properly sized.
How do I know what size (flow rate) tankless water heater I need?
Sizing is based on the simultaneous fixtures you want to run. We calculate total gallons-per-minute (GPM) needed—e.g., shower (2 GPM) + kitchen sink (1.5 GPM) = 3.5 GPM—and factor in groundwater temperature in Corryton (about 55 °F). A professional load calculation ensures the unit can raise that water to 120 °F at the required flow without temperature drop.
What is involved in the installation process and how long does it take?
Most residential swaps are completed in one day: (1) we shut off gas, water, and power; (2) remove your old tank; (3) mount the new wall-hung unit; (4) upsize gas line or add a dedicated 240-V circuit (electric models); (5) install Category III/IV venting or concentric PVC; (6) flush and test the system. Permits and final inspection by Knox County codes are included.
Will my existing gas line or electrical service need to be upgraded?
Possibly. Gas tankless units often require ¾″ lines and up to 199,000 BTU/h. If your current line is undersized, we’ll run a new branch from the meter. Electric models demand 120–150 A dedicated breakers, so homes with 100-A service usually need a panel upgrade. We evaluate this during the free on-site estimate.
How much maintenance does a tankless water heater require in Corryton’s water conditions?
Annual service is recommended. Corryton’s moderate water hardness (6–8 grains) can cause scale, so we perform a 45-minute vinegar or citric-acid flush, clean the in-line filter, and check combustion settings. With routine maintenance, you preserve efficiency and protect the heat exchanger warranty (often 10–15 years).
Are there rebates, tax credits, or financing options available locally?
Yes. High-efficiency gas models (≥0.95 UEF) qualify for a federal 25C tax credit of 30 % up to $600. TVA’s EnergyRight program and Knoxville Utilities Board periodically offer $200–$400 rebates for ENERGY STAR® units. We also provide 0 % APR financing for up to 18 months with approved credit, making the upgrade more affordable.
