FAQs
Why should I choose a wall-mounted, tankless water heater for my Graysville home?
Wall-mounted, tankless units free up valuable floor space, supply endless hot water on demand, and can cut energy use by 25–40 % compared with traditional tanks. Their sealed combustion and direct-vent design are also ideal for the mixed winter/summer climate in Graysville because they lose far less standby heat than a tank that sits in an unconditioned crawlspace or garage.
What size tankless water heater do I need?
Sizing depends on the peak flow rate you expect and the incoming groundwater temperature. In Graysville, winter inlet water can be as low as 50 °F, so a typical three-bath household usually needs a unit that can raise 4–6 gpm by 70 °F (about 160–199 kBtu/h). We perform a fixture-by-fixture audit during your estimate to confirm the correct model so you never run out of hot water.
How long does a professional installation take?
Most straightforward replacements take 4–6 hours, including mounting the unit, running the new Category III vent, upgrading gas lines to ¾″ or 1″ where required, and flushing the system. If we are relocating the heater or upgrading the electrical service, installation can extend to a full day. We schedule City of Graysville inspections immediately after completion so you’re never without hot water overnight.
Do I need special permits or code compliance?
Yes. Graysville follows the Alabama Plumbing & Fuel Gas Code, which requires permits for gas-fired appliances, combustion air verification, and pressure testing of new gas piping. Our licensed plumbers pull all permits, coordinate with the Graysville Building Department, and provide the final inspection report and manufacturer’s commissioning checklist for your records.
How do I maintain a wall-mounted tankless unit?
Annual maintenance is simple: (1) isolate the heater with its service valves, (2) circulate a 5-gallon vinegar solution for 45 minutes to remove mineral scale, (3) clean the inlet filter, and (4) check the condensate neutralizer. We offer low-cost yearly service plans, and performing these tasks keeps the heat exchanger warranty (usually 12–15 years) valid.
What is the typical cost and payback period?
In Graysville, installed prices run $2,800–$4,200 depending on gas line length, venting route, and whether you choose a recirculation pump. Compared with an electric 50-gal tank, the average household saves $100–$150 per year in energy and another $50–$70 by eliminating sacrificial anode replacement. Most customers see a 6–8-year payback, well within the 20-year life expectancy of quality tankless units.
