FAQs
How long do traditional tank water heaters last in Charleston’s coastal climate?
Most conventional tank water heaters last 8–12 years, but Charleston’s salty air, high humidity, and moderately hard municipal water can shorten that span if the unit is not maintained. Annual flushing, anode-rod inspections every 2–3 years, and installing a thermal-expansion tank can help you reach—or even exceed—the upper end of that life expectancy.
What size water heater tank do I need for my household?
A quick rule of thumb is 30–40 gal for 1–2 people, 40–50 gal for 3–4, and 50–80 gal for 5 or more. If you have a soaking tub, multi-head shower, or frequent guests, you may need to upsize. A local plumber will calculate your "first-hour rating" based on peak-hour demand, fixture flow rates, and incoming winter water temperature (around 65 °F in Charleston) to recommend the right tank size and recovery rate.
Are there energy-efficiency incentives for new tank water heaters in Charleston?
Yes. South Carolina offers a $250–$700 rebate through Dominion Energy for ENERGY STAR®-certified heat-pump (hybrid) electric units. Gas utilities provide $50–$150 credits for high-efficiency condensing models (UEF ≥0.81). Federal tax credits of up to 30 % (max $600 for gas, $2,000 for electric heat-pump) are also available under the Inflation Reduction Act. A local expert can file the paperwork and ensure your model meets the required Uniform Energy Factor (UEF) ratings.
How often should I flush my tank water heater, and why is it important here?
Charleston’s water registers 5–7 grains per gallon—technically “moderately hard.” Minerals and sediment settle at the bottom of the tank, forming an insulating layer that forces the burner or elements to work harder. Flushing the tank once a year removes this buildup, restores efficiency, reduces rumbling noises, and extends the life of the tank and heating elements. A plumber can perform the service in about 45 minutes and inspect the pressure-relief valve at the same time.
What signs indicate my tank water heater needs repair or replacement?
• Water that looks rusty or has a metallic taste (likely a failing anode rod or corroded tank) • Popping or rumbling noises even after flushing (hardened sediment or scale) • Moisture or pooling water around the base (possible tank leak) • Fluctuating water temperatures or lukewarm showers • Higher energy bills with no other explanation If your heater is over 10 years old and shows any of these symptoms, replacement is usually more cost-effective than repeated repairs.
Can I install a new tank water heater myself, or should I hire a professional plumber?
Charleston requires a plumbing permit—and, for gas models, a gas-line pressure test—before a new water heater can be placed in service. DIY installation can void the manufacturer’s warranty and may lead to scalding, carbon-monoxide, or flood hazards if regulations aren’t met. A licensed plumber handles permitting, correct venting, T&P valve placement, thermal expansion control, drip-pan drainage, and safe disposal of the old unit. Professional installation also provides labor warranties and ensures you pass the final municipal inspection.
