FAQs
How does a tankless water heater differ from a traditional storage tank heater?
A tankless (on-demand) water heater heats water only when you open a tap, using high-output gas burners or electric coils. Because there’s no storage tank, standby heat loss is eliminated, leading to energy savings of 20–40 % compared with conventional tanks. You also enjoy an unlimited supply of hot water—as long as the unit’s flow-rate capacity isn’t exceeded.
Is a tankless water heater suitable for Charleston’s climate and water conditions?
Yes. Charleston’s moderate winters mean incoming water temperatures are not extremely low, so a tankless unit can reach the desired hot-water temperature with less energy. Although the Lowcountry’s water is considered moderately hard, modern tankless systems include scale-reduction technology and are easily paired with a whole-house filter or softener to maximize lifespan.
What size (flow rate) tankless unit will my home need?
Sizing depends on how many fixtures may run simultaneously and their flow rates. We calculate the gallons per minute (GPM) demanded at peak usage—showers, dishwasher, washing machine, etc.—and select a model that can deliver that total GPM at Charleston’s average incoming water temperature of 65 °F. For most three-bathroom homes, an 8–10 GPM gas model or a 27 kW electric model is adequate, but we perform a site-specific load calculation before recommending equipment.
How long does installation take and will my plumbing need major changes?
A straightforward replacement of a gas tank unit with a gas tankless heater typically takes one working day. We reroute water lines to the new compact unit, install upgraded venting or concentric flue pipe, and add a condensate drain if it’s a high-efficiency model. Converting from electric tank to gas tankless can take 1½–2 days because we run a new gas line and venting. Electric-to-electric conversions usually require a service-panel upgrade, which we can coordinate with a licensed electrician.
What kind of maintenance does a tankless water heater require in Charleston?
Annual maintenance is recommended. We flush the heat exchanger with a vinegar solution to remove mineral scale, clean the inlet filter screen, and verify burner or heating-element performance. Charleston’s mild climate means fewer freeze-protection issues, but if the unit is in an unconditioned space, we winterize it by draining or adding insulation to exposed piping.
Are there incentives or rebates for installing a tankless water heater in South Carolina?
Yes. Dominion Energy South Carolina offers up to a $400 rebate for qualifying ENERGY STAR® natural-gas tankless installations. Federal tax credits under the Inflation Reduction Act provide 30 % of project cost, up to $600 for gas units and $2,000 for qualifying heat-pump water heaters. We handle all paperwork and provide the AHRI certificate so you can claim these incentives.
