FAQs

What are the main benefits of switching to a tankless water heater in Graysville?

Tankless (on-demand) units heat water only when you open a tap, so you eliminate standby heat loss that conventional tanks experience. Homeowners in Graysville typically see energy-cost reductions of 20–40 %, unlimited hot-water supply for back-to-back showers, space savings (the unit hangs on a wall), and product life spans of 18–25 years—almost twice that of a storage tank. Because the local groundwater temperature is moderate, tankless units operate efficiently here without excessive BTU requirements.

How do I know what size tankless water heater my home needs?

Sizing is based on (1) peak flow rate—how many fixtures you want to run simultaneously—and (2) the temperature rise—the difference between incoming groundwater temperature and your desired hot-water temperature (about 120 °F). In Graysville the incoming water averages 58 °F; therefore you need a 62 °F rise. If you want to run two showers (2.5 gpm each) and a dishwasher (1.5 gpm) at once, you’ll need about 6.5 gpm at a 62 °F rise, which translates to a 180–199 kBTU gas unit or a 27-kW electric model. Our technicians perform a quick whole-house demand calculation during the estimate to recommend the correct unit.

Can a tankless heater be connected to my existing plumbing, gas, or electrical service?

In most cases, yes. We tie the new heater into the existing hot- and cold-water lines with minimal re-piping. Gas models usually need a larger ¾-inch gas line and a Category III or IV stainless-steel vent; we verify your meter and regulator can supply the extra BTUs. Electric models require a 200-amp service panel and dedicated 40–60 amp breakers. During your on-site assessment we check pipe sizes, vent routes, electrical capacity, and code compliance so you know up front if any upgrades are necessary.

How long does installation take and what is the process?

A straightforward replacement of a gas tank with a gas tankless unit takes about 4–6 hours. Complex jobs that involve upsizing gas lines, relocating the unit, or converting from electric to gas can extend to a full day. We start by draining and removing the old tank, mounting the new wall-hung unit, running gas/electric and water connections, installing the vent or condensate line, pressure-testing the system, and finally commissioning the heater to manufacturer specs. Before we leave we show you how to operate the controller and register your warranty.

Are permits, inspections, or rebates required in Graysville?

Yes. The City of Graysville and Jefferson County require a mechanical or plumbing permit for any water-heater replacement. We pull the permit on your behalf and schedule the final inspection. Many customers qualify for Alabama Power or Spire gas utility rebates—typically $250–$500 for high-efficiency models—as well as a federal tax credit of 30 % of the project cost (up to $600) under the Inflation Reduction Act. We provide all model numbers and efficiency documentation so you can submit the rebate forms easily.

What maintenance does a tankless water heater need after installation?

To keep the heat exchanger free of scale, manufacturers recommend a yearly service in areas with moderately hard water like Graysville (about 6–7 grains/gallon). The process involves isolating the unit and circulating white vinegar or a citric-acid solution for 30–45 minutes. You should also clean the inlet screen filter every 6 months and inspect the vent for obstructions. Our plumbing team offers an affordable annual maintenance plan that preserves the warranty, maximizes efficiency, and records service history for future resale value.
