FAQs
What size tank water heater is best for a typical Charleston household?
Sizing depends on the number of people and simultaneous hot-water uses. In Charleston, a 40–50-gallon gas unit or a 50–55-gallon electric unit usually handles a family of 3–4. Larger families (5–6 people) may need 66–80 gallons. We calculate demand by looking at peak-hour usage, number of bathrooms, laundry loads, and any soaking tubs. During your estimate we perform a quick Gallons-Per-Hour (GPH) analysis and recommend the smallest model that meets your needs to keep both upfront and energy costs down.
How long does a tank water heater installation take and what should I expect on installation day?
Most standard replacements are completed in 2–4 hours. We: 1. Shut off water, gas or electricity, and drain the old tank. 2. Disconnect and haul away the old unit. 3. Bring the new heater in, set it on a code-approved drain pan, and connect water, gas, or electric lines with new flexible connectors. 4. For gas models we install a new vent or line it to meet S.C. Mechanical Code and perform a leak test. 5. Fill, purge air, adjust temperature to 120–125 °F, and relight or energize. 6. Obtain City of Charleston inspection if required. We protect floors, clean the work area, and review the warranty and maintenance tips before leaving.
Do I need a permit to replace or install a tank water heater in Charleston?
Yes. Both the City of Charleston and Charleston County require a plumbing/mechanical permit for water heater replacement or new installation—gas or electric. Homeowners can pull a permit for their own occupied residence, but most choose a licensed master plumber to handle the paperwork, scheduling, and the final inspection. Our team secures the permit, installs to the 2021 International Plumbing & Fuel Gas Codes adopted by South Carolina, and coordinates the inspector’s visit so you stay fully compliant and protected by insurance.
What does a typical tank water heater installation cost in the Charleston area?
For a like-for-like replacement the average total ranges from $1,200–$2,200, including the heater, permit, labor, and haul-away. Pricing varies by: • Fuel type (gas units cost a bit more than basic electric models). • Tank size and efficiency rating (standard vs. high-efficiency or heat-pump units). • Required code upgrades—seismic strapping, expansion tank, drain pan with drain line, or new venting. • Accessibility (tight crawlspaces or an attic lift can add labor). We provide a written, no-surprise quote after an on-site assessment.
Are high-efficiency or heat-pump water heaters a good choice for Charleston’s climate?
Absolutely. Charleston’s mild winters and long cooling season make hybrid electric heat-pump water heaters very cost-effective—often cutting water-heating costs by up to 60 %. Rebates from Dominion Energy or Santee Cooper can offset $400–$800 of the upfront price. For gas, look for ultra-low-NOx burners and 0.64–0.70 UEF ratings. We compare operating costs for all options so you can see the payback period before you decide.
How do I maintain my new tank water heater near the coast?
Salt-laden air and Charleston’s slightly hard water can shorten a heater’s life if ignored. Follow these tips: • Drain 2–3 gallons from the tank every 6–12 months to flush sediment. • Have the anode rod inspected after year 3 and replaced when more than 6 inches of core wire is exposed. • Test the T&P relief valve yearly. • Keep combustion air screens (gas) and exterior heat-pump filters clean. • Maintain 2 feet of clearance around the unit and check for leaks on the cold-water inlet and relief line. Our Comfort Club includes an annual tune-up that keeps your warranty valid and helps your heater reach or exceed its 10–12-year expected lifespan in Charleston’s coastal environment.
