FAQs
What advantages does a tankless water heater offer over a traditional storage-tank unit?
A tankless (on-demand) water heater heats water only when a fixture calls for it, eliminating standby heat losses that occur in storage tanks. This can cut water-heating energy use by 25–40 %, provide an unlimited supply of hot water (as long as the unit is sized correctly), free up floor space, and typically last 5–10 years longer than a tank model. Because there’s no stored water, risks of tank leaks and related flood damage are also greatly reduced.
How long does a professional tankless water heater installation usually take in a Cowan home?
Most single-family installations are completed in one business day. Our crew arrives with pre-assembled venting, gas and/or electrical components, performs any code-required upgrades, mounts the unit, tests the gas pressure or electrical load, flushes the lines, and commissions the heater. Complex jobs—such as relocating the unit, upsizing the gas line, or adding 240-V wiring—can extend the project to two days, but we’ll outline the schedule during the in-home assessment.
What size (flow-rate) tankless unit do I need for my household?
We size your unit by calculating simultaneous hot-water demand (gallons per minute, or GPM) and the required temperature rise between Cowan’s incoming water (typically 55–60 °F) and your desired 120 °F setpoint. For example, two showers running at once (2 GPM each) plus a dishwasher (1 GPM) requires about 5 GPM. If you need a 60 °F rise, you’d select a gas unit rated at ≥5 GPM at that rise (usually 180,000 BTU) or an electric model rated at 27 kW. During the consultation we measure fixtures, discuss usage patterns, and recommend the most efficient model for your lifestyle and budget.
Will I need permits or inspections for a tankless water heater installation in Cowan?
Yes. Franklin County and the City of Cowan enforce the 2018 International Plumbing and Fuel Gas Codes. A mechanical/plumbing permit is required for new or replacement water heaters, and gas-fired units also need a gas pressure test. Our licensed plumbers pull all necessary permits, coordinate with the local building official, and remain on-site for the final inspection, ensuring your installation meets code and maintains manufacturer warranty coverage.
What maintenance does a tankless water heater require to keep its warranty valid?
Manufacturers recommend an annual service that includes flushing the heat exchanger with food-grade white vinegar or a citric-acid solution to remove scale, cleaning the inlet filter, and checking venting, burner, and condensate drain components. In Cowan’s moderately hard water (6–8 grains per gallon), we also suggest installing a whole-house sediment filter and performing a scale flush every 12–18 months. Routine maintenance prevents efficiency losses, extends the unit’s lifespan, and keeps the warranty—often 12–15 years on the heat exchanger—fully intact.
Are rebates or utility incentives available for tankless water heaters in Cowan?
As of this year, Tullahoma Utilities and Duck River EMC both offer $200–$400 rebates for Energy Star–qualified gas or electric tankless units. Homeowners may also claim a 30 % federal tax credit (up to $600) under the Energy Efficient Home Improvement Credit. We handle the paperwork, provide the AHRI certificate, and guide you through any additional Tennessee Valley Authority (TVA) incentives, helping you maximize savings on your high-efficiency upgrade.
