FAQs
How does a tankless water heater produce hot water and what makes it different from a conventional storage-tank unit?
A tankless (on-demand) water heater senses flow the moment a hot-water tap is opened, ignites a high-efficiency gas burner or activates electric elements, and heats water as it passes through a heat exchanger. Because water is only heated when you need it, there is no standby tank that continually loses heat. The result is an endless supply of hot water, up to a manufacturer-specified flow rate, and energy savings of 20-40 % compared with most standard tanks.
What are the main benefits of installing a tankless water heater in Huntsville’s climate?
Huntsville’s mild winters and warm groundwater temperatures (≈60–65 °F) allow tankless units to reach set-point with less energy, increasing efficiency. Homeowners typically gain: • Lower utility bills due to reduced standby loss • Space savings—units mount on a wall inside or outside • Longer lifespan (20+ years vs. 8–12 for tanks) • Reduced risk of tank leaks and water damage • Federal tax credits (up to 30 % of the unit cost) and possible Huntsville Utilities rebates for high-efficiency gas models.
How do I know what size (flow-rate) tankless unit my home needs?
Sizing is based on two factors: 1) total flow rate of fixtures you may use at once (shower + kitchen sink + washing machine, etc.), and 2) the temperature rise required—from incoming water temperature to your desired set-point (usually 120 °F). In Huntsville the rise is roughly 60 °F. A typical 2-bath, 3-bedroom home needs a gas unit that delivers 6–8 gpm at a 60 °F rise; larger households or simultaneous soaking tubs may require 9–11 gpm. Our technicians perform an onsite fixture count and load calculation to recommend the right model so you never run out of hot water.
Do I need a permit or inspection for a tankless installation within Huntsville city limits or Madison County?
Yes. The City of Huntsville and Madison County both require plumbing permits for water-heater replacements, and a mechanical/gas permit if the unit is gas-fired. After installation a municipal inspector verifies proper venting, gas sizing, combustion air, and pressure relief discharge. When you hire us, we pull all necessary permits, schedule the inspection, and provide you with documentation for your records and future home resale.
How long does installation take and will my plumbing or gas lines need upgrades?
A straightforward swap of a gas tank for a gas tankless unit in the same location typically takes 6–8 hours, including mounting the heater, rerouting water lines, installing a condensate drain, and completing combustion-air/vent piping. If your existing gas line cannot supply the higher BTU demand, we’ll upsized the line or run a dedicated branch—adding 1–4 hours. Electric tankless retrofits may require a service-panel upgrade because units draw 120–160 amps; we coordinate with a licensed electrician if needed. Before any work begins you receive a written estimate detailing all necessary upgrades.
What maintenance is required and how often should my tankless water heater be serviced in North Alabama?
To preserve warranty coverage and efficiency you should: • Flush the heat exchanger annually (or every 6 months if your water hardness exceeds 12 grains) with a vinegar solution to remove scale • Clean inlet water and air filters quarterly • Check condensate drain and vent for obstructions. Our service plan includes an annual descaling, full diagnostic check, and firmware update where applicable. Regular maintenance keeps efficiency high, extends the heat exchanger’s life, and prevents costly error codes.
