FAQs
What are the main benefits of installing a tankless water heater in my Cowan home?
Tankless units deliver endless hot water on demand, eliminate standby heat loss from a storage tank, free up floor space, and typically last 18–20 years—about twice as long as a conventional tank. Homeowners in Cowan also appreciate lower energy bills (up to 40 % savings) and the reduced risk of catastrophic tank leaks.
How do I know if my household’s hot-water demand is suitable for a tankless system?
A technician will calculate your peak flow rate—the total gallons per minute (GPM) your fixtures might require simultaneously—and match it to a properly sized heater. Most Cowan households with one to three bathrooms can be served by a single whole-house unit; larger homes may need two units in parallel or a dedicated unit for high-demand fixtures like soaking tubs.
What is involved in the installation process?
We start with a free on-site assessment to evaluate gas or electrical service, venting paths, and water line location. On installation day we remove the old tank, mount the compact tankless heater on the wall, upgrade gas lines or electrical circuits if required, install stainless-steel venting, add isolation valves for easy flushing, and set the digital temperature controller. Most projects in Cowan are completed in one day.
Will my existing gas or electrical service need to be upgraded?
Possibly. High-output gas units may require a ¾-inch gas line and proper combustion air; electric models often need 150–200 amp service with multiple 40–60 amp breakers. During our assessment we measure your current capacity and quote any necessary upgrades so there are no surprises.
How much maintenance does a tankless water heater require?
Annual or bi-annual descaling is recommended, especially with Cowan’s moderately hard water. We connect a small pump to the built-in isolation valves and circulate a vinegar or citric-acid solution for about 45 minutes. This keeps heat exchangers efficient and maintains the manufacturer’s warranty. We also inspect the vent, combustion chamber, and filter at the same visit.
Are there rebates, financing, or warranties available?
Many high-efficiency tankless models qualify for federal tax credits under the Inflation Reduction Act, plus local utility rebates for Tennessee Valley Authority (TVA) customers in the Cowan area. We offer 0 % financing for up to 18 months OAC, manufacturer heat-exchanger warranties up to 15 years, and our own 5-year labor guarantee on every installation.
