FAQs
How does a tankless water heater work and is it right for my Crab Orchard home?
Unlike a traditional storage tank that constantly heats 40–80 gallons of water, a tankless (on-demand) unit uses high-efficiency gas burners or electric elements to heat water only when a hot-water tap is opened. Cold water flows through a heat exchanger and exits at the desired temperature within seconds. That means no standby heat loss, unlimited hot-water supply, and a space-saving wall-mount design—an advantage for both smaller residences and larger homes in Crab Orchard that need multiple bathrooms supplied at once.
What size on-demand water heater do I need?
Sizing is based on two factors: (1) total flow rate you expect to use simultaneously, measured in gallons per minute (GPM), and (2) the temperature rise required (difference between incoming groundwater and the target hot-water temperature). In Crab Orchard, incoming water averages 50–55 °F. For a typical shower (2.0 GPM) plus a dishwasher (1.5 GPM) running together, you’d need 3.5–4 GPM at a 70 °F rise. A family of four often selects a 7–9 GPM gas unit or an appropriately sized electric model. We perform a free in-home assessment to confirm the exact capacity so you never run out of hot water.
How long does installation take and will my water be off?
Most residential installations are completed in one day. We start by shutting off water and gas/electric service to disconnect your old tank. Piping, venting, gas line upsizing (if needed), and electrical work are then completed. The water is typically off for 2–4 hours; we coordinate with you so disruption is minimal. After mounting the new unit, we perform a full system purge, pressure test, and first-run to verify safe, efficient operation before restoring service.
Do tankless units really save money on energy bills?
Yes. ENERGY STAR®-rated gas tankless heaters are 24–34 % more efficient than conventional storage tanks, and efficiency rises to 40 % when you install low-flow fixtures or use moderate demand. For a Crab Orchard household using natural gas, that translates to average annual savings of $80–$150. Electric tankless models avoid standby losses altogether and are ideal if you already have a high-capacity electrical panel or solar PV array.
What kind of maintenance is required and can you service it locally?
Tankless heaters need an annual flush with food-grade vinegar or a descaling solution to remove mineral buildup, especially with our moderately hard Crab Orchard water (about 4–6 grains per gallon). Our licensed technicians provide a maintenance plan that includes filter cleaning, burner inspection, vent check, and software diagnostics. Regular service keeps your warranty valid and extends unit life beyond 20 years.
Are there incentives, rebates, or tax credits available for Crab Orchard residents?
Yes. Federal Inflation Reduction Act tax credits cover 30 % of the installed cost of qualifying ENERGY STAR® gas or electric tankless heaters, up to $600. Mountaineer Gas and AEP Appalachian Power periodically offer $100–$250 utility rebates for high-efficiency water heaters. We handle all paperwork, provide required AHRI certificates, and apply the rebate directly to your invoice so you enjoy instant savings.
