FAQs
Why should I choose a tankless water heater for my Collegedale home?
Tankless units heat water on demand, eliminating the standby energy losses of a storage tank. You’ll benefit from endless hot water for back-to-back showers, up to 40–60% lower energy costs compared with older tank models, and a wall-mounted design that frees up floor space. Collegedale’s moderate climate also helps tankless heaters operate at optimal efficiency year-round.
How do I know what size tankless water heater I need?
Sizing is based on two factors: the flow rate you need (measured in gallons per minute, or GPM) and the temperature rise (the difference between incoming water temperature and your desired hot-water temperature). In Collegedale, incoming water averages 55–60 °F. For simultaneous use of two showers and a kitchen sink, you may need 6–8 GPM with a 60 °F rise. Our plumbers perform a load calculation on site to recommend the correct model so you never run out of hot water.
What is involved in converting from a tank to a tankless water heater?
A licensed plumber will remove your existing tank, install a mounting bracket for the new unit, and upgrade gas or electrical service if necessary. Most gas tankless units require ¾" gas lines and Category III stainless-steel venting, while electric models may need 200-amp service and dedicated breakers. We also install isolation valves for easy future maintenance and flush the lines to clear debris before startup. The average conversion in Collegedale takes one business day.
Will a tankless water heater work with my hard water?
Yes, but hard water shortens heat-exchanger life if left untreated. Collegedale’s water hardness ranges from 100–130 ppm, which is considered moderately hard. We recommend adding a whole-home water softener or a point-of-use scale inhibitor to minimize mineral buildup. Regular annual descaling—often included in our maintenance plans—keeps your warranty valid and maintains peak efficiency.
What maintenance does a tankless water heater require?
Unlike tanks that simply need periodic flushing, tankless units should be descaled annually and have their inlet screens cleaned to remove sediment. We run a vinegar or manufacturer-approved solution through the heat exchanger for about 45 minutes, inspect the burner (gas) or elements (electric), and update firmware on Wi-Fi–enabled models. Our Collegedale customers can enroll in an affordable service plan that schedules this visit automatically.
Are tankless water heaters eligible for rebates or tax credits in Collegedale?
Yes. Tennessee’s Valley Renewable Energy Standards offer up to $300 in local utility rebates for ENERGY STAR-qualified gas tankless models. Additionally, the 25C federal tax credit covers 30% of the installed cost, up to $600, for qualifying units placed in service through 2032. We complete the rebate paperwork and provide the AHRI certificate so you can claim the incentives without hassle.
