FAQs
What advantages does a tankless water heater offer over a traditional storage tank for Hixson homeowners?
Tankless units heat water on demand, so you never run out of hot water during long showers or when multiple fixtures run simultaneously. Because they don’t keep 40–50 gallons of water hot all day, they use 25–40 % less energy, lowering monthly utility bills. Their compact wall-mounted design frees up floor space and eliminates the risk of a catastrophic tank leak. With Hixson’s relatively mild winters, a properly sized unit also performs very efficiently because inlet water temperatures do not drop as dramatically as they do farther north.
How do I determine the correct size (flow rate and temperature rise) for my tankless water heater?
Sizing is based on two factors: 1) the total gallons-per-minute (GPM) you expect to use at one time, and 2) the temperature rise needed to reach your desired hot-water temperature. We add up the flow rates of all fixtures you might run simultaneously—for example, a shower (2 GPM) plus a dishwasher (1.5 GPM) equals 3.5 GPM. In Hixson, incoming water averages 60 °F. If you want 120 °F water, you need a 60 °F rise at 3.5 GPM. A unit rated around 7 GPM at a 45 °F rise would comfortably meet that demand, leaving a cushion for peak usage. Our technicians perform this calculation during your on-site evaluation to recommend the optimum model.
Will I need plumbing, gas, or electrical upgrades when switching to a tankless system?
Often, yes. Gas units generally need a larger gas line (¾″) and a Category III or IV stainless-steel vent because they fire at a higher BTU rate. Electric models require 120–240 V service with dedicated breakers that can handle 100 A or more, which many older panels cannot provide. On the plumbing side, we install isolation valves and a service port to make future maintenance easy, and we may reposition water lines to reach the new wall location. Before work begins we give you a fixed-price proposal that covers any necessary upgrades so there are no surprises.
How long does installation take, and what should I expect on the day of service?
Most residential conversions are completed in one business day. We start by draining and removing your old tank. Next we hang the new tankless unit and run any required gas, water, condensate, or electrical lines. Then we install the venting, pressurize and test the system, and program the digital controller to your comfort settings. Finally, we show you how to adjust temperature, perform quick maintenance checks, and register the warranty. Our team protects floors with drop cloths and cleans the area before leaving so you can start enjoying endless hot water immediately.
What maintenance does a tankless water heater require in the Hixson area?
Tankless heaters should be flushed annually to remove scale, especially in Hamilton County where water hardness averages 6–8 grains per gallon. We connect hoses to the isolation valves and circulate a vinegar solution for about 45 minutes, then rinse, check the burner or heating elements, and clean the inlet screen filter. This simple service keeps efficiency high, prevents error codes, and preserves the 15- to 20-year life expectancy. We offer an affordable maintenance plan that schedules the flush automatically each year and records service for warranty purposes.
Are rebates or tax incentives available for installing a tankless water heater in Hixson?
Yes. Tennessee Valley Authority (TVA) occasionally runs energy-efficiency rebates of $200–$500 for qualifying gas tankless installations, and many natural-gas providers offer bill credits as well. In addition, the 2023 federal Energy Efficient Home Improvement Credit provides a tax credit of 30 % of the project cost, up to $600 for gas units meeting the highest efficiency tier. We supply the manufacturer’s certification and detailed invoice you’ll need for your tax preparer, and we’ll help you complete any utility rebate paperwork at no extra charge.
