FAQs
What are the main benefits of switching to a tankless water heater in Charleston’s climate?
Tankless units heat water on demand, so you never run out of hot water during long showers or back-to-back laundry loads. Because Charleston’s winters are generally mild, the incoming water temperature is higher than in many parts of the country, which allows tankless heaters to operate even more efficiently here. Homeowners typically see energy-use reductions of 25–40 %, enjoy space savings because the unit mounts on a wall, and avoid the risk of tank leaks or catastrophic ruptures.
How long does a typical tankless water heater installation take, and will my water service be interrupted?
Most residential installations in the Charleston area are completed in one business day. We begin by shutting off the existing water and fuel lines, remove your old tank, mount the new tankless unit, connect gas/electric, water, and venting, then test the system. Your water service is usually off for 2–4 hours; we coordinate the timing with you so disruption is minimal. If extensive gas-line upsizing or electrical work is required, the job may extend into a second day, but we will communicate that up front.
Do I need to upgrade my gas or electrical service for a tankless unit?
It depends on the model you choose. Gas tankless heaters typically need a ¾-inch gas line and a higher BTU rating than storage tanks. During our free in-home evaluation we measure your existing line pressure and pipe size; if an upgrade is necessary, we’ll include that scope in the quote. Electric tankless units often require 120–150 A of dedicated capacity and multiple 240-V breakers—something many older Charleston homes lack. We’ll provide a load-calculation and, if needed, coordinate with a licensed electrician or Dominion Energy for panel upgrades.
Are permits required in Charleston, and do you handle them?
Yes. The City of Charleston and surrounding municipalities require plumbing and, for gas models, mechanical permits before installation. Proper venting and combustion-air clearances are strictly enforced under the 2021 International Residential Code adopted locally. We take care of all permitting, code compliance, and the final inspection, so you don’t have to navigate city hall or worry about red tape.
How much can I expect to save on energy bills, and are there any local rebates or tax incentives?
Most homeowners see annual savings of $80–$150 compared with a standard 50-gal gas tank, depending on usage. Electric tankless units can save even more if paired with time-of-use rates. South Carolina residents may qualify for a state income-tax credit up to 25 % of the installed cost (SC Code §12-6-3587). Dominion Energy offers a $200 rebate for ENERGY STAR® certified gas tankless heaters, and some cooperatives provide bill credits. We’ll file all rebate paperwork for you and supply the tax documentation at checkout.
What kind of maintenance does a tankless water heater require after installation?
Unlike tanks that corrode inside, tankless units mainly need descaling to remove mineral buildup. Charleston’s water is moderately hard, so we recommend flushing the heat exchanger with a vinegar solution once a year (takes about 45 minutes). We install isolation valves to make this quick and DIY-friendly, or you can schedule us to perform it. Also, clean the air filter and check the condensate line on high-efficiency models annually. With proper care, most tankless heaters last 20+ years—double the life expectancy of traditional tanks.
